master teacher summer institute

This week starts a new beginning in my journey. I checked in through Human Resources at the State Department of Education as the new Science Director. As soon as I got done, it was off to the National Center for Employment Development in Norman, OK to begin the Master Teacher Summer Institute.

This program is an exciting one in which teachers work in their content area for part of the time and in their geographical region for the rest of the time. There is a strong focus on building relationships and that is something I appreciate the most. We spent most of yesterday with Tina Boogren from Solution Tree (Richard Marzano's company) working through the book, "The Highly Engaged Classroom". Tina is a fantastic speaker and educator who has something to share with teachers from all content areas and all grade levels. I really enjoyed learning some new strategies on how to "hook" students and then keep them engaged in the learning process.

This morning, several of the other Curriculum Directors presented on the idea of Multiculturalism in Education. They worked through about 3 hours of information, sharing strategies for building community in a diverse classroom throughout. The most interesting to me was Bafa' Bafa', a simulation in which learners engage in role play as people from different countries. This simulation really magnifies the cultural clues and hidden meanings that exist within different cultures. It's quite enlightening and I recommend it highly! (Good Lord! I just realized I've linked to the site for purchasing the program. Expensive, but worth it.)

Finally, this afternoon, we were able to work as content areas and Tiffany Neill brought some great inquiry lessons to us. Not only did we do some inquiry, we spent time taking it to the next level and thinking about what everyone else did with the data we gathered. Everyone collected data (a skill on which every student needs to work) and then we were told to create a representation of the entire class set of data to share. 4 different groups = 4 different representations. We spent time going around looking at what each thing represented (or at least what we thought it represented) and giving a critique, as well.

Here's where things got interesting. Groups went back and read what had been said for a critique and had the chance reflect/modify or to defend what they had done. This part of the process is SO important! We have to work on more opportunities to give students the chance to take a stand and argue their point. It is almost like debate. They present evidence to support their position. This is the next level of learning; it is beyond the content and takes students to a higher level of thinking and a deeper level of understanding. This is where the Common Core will take us: increased rigor at a deeper level. Remember the Sunday School song "Deep and Wide?" That is not the Common Core, its only deep, not wide.

Tomorrow, we will finish up our content time and then work together as groups for Regional Conferences. I'm interested to see exactly what that Regional Conference is going to look like. I'm definitely learning something everyday. I might even be beginning to wrap my brain around bits of this job.

new beginnings

This has been a week of transition. I have accepted the position of Science Curriculum Coordinator for the Oklahoma State Department of Education. I've said for a long time that teaching physics at Putnam City High School was the last job I would ever want, meaning it is literally the last job I ever wanted to have. However, sometimes opportunities present themselves and you feel like you cannot pass them by (lest they do not return!)

In my next to last Master's class, I was working with a group of people and one of them said, "You know that the Science Curriculum Director position is open? You would be awesome at that, you should apply!" I said, "No, I didn't know that. I'm not sure that's something I would want to do. I mean, I'd have to leave my classroom!" So I went down home that evening after class and talked to @mishelleyb and we decided that the only way I would know if I wanted to do that job was to apply and interview. So, in April I applied. Knowing how little experience teaching I have had, I did not think I had any chance at even interviewing for the job. Honestly, once I applied, I totally forgot about it.

I moved forward with the State Teacher of the Year application and focused on teaching to the best of my ability. I didn't give Science Director another thought. As we were on our way to Philadelphia for the International Society of Technology in Education Conference, I received a phone call from the Asst. Superintendent of Curriculum about presenting at a conference in Oklahoma City. In the course of that conversation she mentioned my application and assured me that I would be called for an interview. This was completely out of left field as I was so nervous about making the finals for State TOY. At that time, I was informed that there might come a time when I would have to choose between TOY and Science Director. Uh, can you say no-brainer? TOY is a big honor. In fact, for me, its been huge. However, to be able to influence teachers beyond my district and to be able to affect change in science education versus being a spokeperson for the vocation of teaching? Yeah, not really a difficult decision.

What was a difficult decision was leaving my classroom. It was incredibly hard to think about leaving my students to be taught physics by someone else. However, knowing I would have some influence on that teacher and others who teach science across the State of Oklahoma helped make this much less difficult. In the course of the interview I learned that a significant part of this job is focused on teaching teachers, e.g. conducting professional development. This is something about which I am passionate. In fact, I'm as passionate about that as I am about teaching physics and earth science, so how could I say if they offered?

To make a long story short, I interviewed for the job last week and they offered the position to me on Monday and I have accepted.

I start next Monday and I believe I am going to hit the ground running. We are conducting Master Teacher Academy 3 days of next week and then I am going to a workshop to begin assisting in the process of developing a STEM plan for the State of Oklahoma. I mean, really? That's the kind of responsibility I have now? Oh, my. What have I gotten myself into? I've certainly moving out of my comfort zone. It feels like starting over in teaching. I feel like I'm about to start my first year again.

I do know this, I am going into an office in which there are other Directors who are experienced and are excited about me coming to work with them. We are moving towards the Common Core and we have already re-done our science standards and I'll be helping to implement those. The team I am going to work with is awesome from what I hear.

I'll be continuing this blog in its current format. I'm continuing my education and this will simply be a place to share what I am doing in my teaching (I'm still adjuncting 3 classes for SNU) and my learning (I am beginning to understand just how much I don't know). If you enjoy reading, I hope you will continue to do so.

Critical Thinking in Mulitcultural Education

The chapter on "Promoting Democracy and Critical Thinking" in Choosing Democracy really hits a note with me. I am a firm believer in teaching critical thinking and I think many (if not most) students graduate from high school with inadequate critical thinking skills. This leaves them at a major disadvantage when it comes to being a productive citizen (working, voting, making everyday decisions) or continuing their education (the ability to be successful in higher education).

This comes as a result of teachers who have preconceived ideas about their students. That or they are so lazy, the easy way to do things is to continue on with the same old curriculum, doing the same drill and practice exercises and having students memorize the same stuff they have been doing for the last 20 years.

Students need to be able to take control of (or at least have a say-so in) their education. This is quite difficult for high school teachers, since students are coming to us from middle school where they are being taught "the right answers". I don't mean to lay the problems of the education system squarely at the feet of the middle school teachers. But in my school, a very large number of students come to me without the proper foundation to adequately draw conclusions, evaluate the validity of evidence, or otherwise make decisions regarding scientific investigations. Therefore, I am drawing my own conclusions.

But, I'm not here to crucify the middle school teachers. What I want to know is what to do about it. In my experience, the only thing I can do is try to teach students the critical thinking skills needed to make them more successful in life. This comes about in my class through leveled questions (with resultant class-wide conversations), graphic organizers (teaching chart building skills), and encouraging students to think for themselves. I purposely give students problems to which I do not know the answers. This way, I am not able to give clues other than guiding their questioning, relying on the basic concepts.

I prefer to think of it as teaching students to swim by pushing them off into the end of the pool. Fortunately, I am waiting there in the water to help keep their heads above water if things get a bit too deep.

This subject is especially appropriate right now since we are watching Contact in Earth Science. Students are confronted by some ideas that make them squirm a bit in their seats. I believe Piaget called this a "cognitive dissonance" or "disequilibrium". I have many students who are members of some religious sect, but are only so because their parents are. I try to challenge students to begin to think for themselves. One of the questions I pose to students is "But why do you believe that?"

In science, as in any discipline, its important for students to recognize that there is a major difference between belief in something and acceptance of something. Facts are things we accept: the birth/death of a friend, the beginning/end of a relationship, etc. I've known people who choose not to accept the facts (some of them related to my examples!)But belief requires an additional ingredient: faith. The ability to buy into an idea without any facts. It is based on emotion, feelings, ideas, but there is no evidence to support it.

So many students come to high school without the knowledge of the difference in these two concepts. This misconception handicaps them (sometimes for life) if they are not able to learn to think for themselves. I am happy to have students talk about religion in my classroom (in fact I have mentioned my faith on more than one occasion, when asked), but I try to get students to look inside themselves and determine why they believe the way that they do and get away from the tried but false adage of "because I was raised that way".

I've grown up a lot over the last 6 or 7 years and don't necessarily agree with everything I was taught as a child. This is due in no small part to my experiences in higher education. I've learned to think for myself and hope to instill this idea in my own children and my students. Its a very hard balance. I admit, in my parenting and in my classroom, I feel as though I am walking a tightrope trying to respect the ideas of my student's parents, while trying to persuade them to think for themselves and "question everything." I'm probably overstating the case there, but I get as close to the "question everything" line as I can without crossing it.

I would argue that critical thinking (and therefore democracy promotion) is the most important aspect of any student's educational experience. Students who miss out on this part of an education (as I stated earlier) can be handicapped for life. How can we expect them as citizens to vote responsibly if they are not able to evaluate the validity of the evidence presented in favor of, or against, a candidate?

Would it be out of the realm of possibility to consider critical thinking (or a lack of it) is the reason our educational system is in its current state? I mean, if students can't think critically and therefore cannot be informed voters, how do we know we have the best possible people running our government? For that matter, if they are not good critical thinkers, they are more likely to be apathetic about government anyway. A select few choose the people who make all the decisions that matter most to people who are in poverty. What is going on here?

Life as I know it

Right now, life as I know it is about to get incredibly busy. Is this a problem? No, I don't think so. Life as I know it is getting busy because I have purposely chosen to do things that are important to me. They are activities about which I am passionate. No surprise that they all revolve around education.

I'm working on my syllabus for Physics for the upcoming year and thinking about my kids (yes, my own children) being my students for the upcoming year. One of those two will be a Senior here at Putnam City HS. (How many people have the opportunity to spend every single school day of their child's Senior year with them? Hooray!) I initially was thinking, "I've got to make this the best year ever", just for Jess' and JC's sake. But then I realized, why should this year be special for them? I want this year to be the best, but really I want it to be the best year for ALL of my students. I hope to build deeper relationships, get to know my content at a deeper level, and motivate students like never before. School starts on Thursday of next week. But, between now and then, it's going to be crazy.

I've already started teaching at SNU as an adjunct professor in their Bridge program. I'm driving to Tulsa once a week, on Monday nights, to teach Earth's Natural Disasters. I have another class, by the same name, here at the Bethany campus that starts a week from this Monday. Teaching adults is definitely a new experience for me and I am really enjoying it. I have been able to pass on my passion for Science through this experience and hopefully, it's just the beginning! (I'll be learning to be an Instructor in Astronomy and Geomorphology during the month of December).

I'm continuing in my Master's program in Curriculum and Instruction and that one night a week keeps me busy every weekend with lots of writing, reading, and thinking about my classes. This really is the reason I'm a bit stressed about the next school year. I have so many ideas and new things to try that I've been learning over the summer that it's going to be like starting from scratch. In some ways its exciting to think about a brand-new group of students with whom I can share my passion for Physics. In other ways, I feel a bit overwhelmed.

I'm going to try to take 6 hours as a "traditional graduate" student in some "by arrangement" classes to make up for my decision not to do National Board Certification. I need the hours to finish the Master's. That won't happen until the Spring, but I'm trying to get it all "lined out" so we are on track to walk at graduation in May and be done with degree #2.

I've been asked to teach several professional development classes between now and next Thursday. I'm doing an in-house webpage class, talking about assessing students through technology integration, and I'm trying to work on integrating our school calendar into all teacher webpages. It's really a lot of fun to be given a problem and asked to solve it using technology integration. I am learning that is something at which I can be successful. I have some really great colleagues that I am able to collaborate with on projects and that makes it a wonderful experience.

Science. Technology. Education. Those are three things I can get excited about! When someone asks me to share about any of those? How can I refuse? Even if it means I am (possibly) over-extending myself, I can't say no.

I have learned so much about myself over the last 5 years. My education at SNU and my experience teaching Physics at Putnam City has been the most rewarding vocational time of my life. Have I made mistakes? Sure! Will I still make mistakes this year? More than likely. Will I learn something new every single day? I sure hope so. If you see me in the halls and I seem a bit distracted, please don't take it personally. Just know that I am thinking about the next opportunity to share my passion.

why should students take ap classes anyway?

I have my own opinions on the matter and plan to share them here. In case I forget to ask, I'd love to hear what you have to say. I'll admit, my opinion won't be the popular one, but it is, after all, just an opinion and is not based in research or even very much experience (this is my 3rd year to teach).

I teach AP Physics. Wait, let me go back a little further. AP classes are supposed to be taught at a college level. The AP stands for Advanced Placement and is designed to prepare students for a test that can gain them college credit in the class taught, i.e. psychology, calculus, biology, spanish, etc. I'd love to hear input from some college freshmen that took AP classes their senior year and then took an equivalent class during their first year of college. Was it on the same level? Was it harder? Easier? Was the workload the same?

So, whether you are ready for my opinion or not, here it comes. Students taking AP classes should not be trying to take the class to get credit in college. Sure. College credit is a great benefit of taking the class, but should it be the primary objective? When I asked student in my AP physics class to tell me why they were taking the class, the overwhelming majority of them told me "so I can get college physics credit". However, most of these students will be entering college as a science or math major. My class is probably not (quite) up to the rigor of a college class, because of that fact, I am constantly trying to improve it and make it more like the post-secondary level it should be.

Bear in mind there are students in my class who have never made anything less than an "A" on their transcript. The parents of these students call and complain when they are making a "B" or (heaven forbid) even a "C". This is the argument I hear, "my student has NEVER made less than an "A", why are you not teaching them well enough so that they can be successful (meaning get an "A") in your class?" I hate to break it to you parents, there are a lot of students who go to college and don't make all "A's"! There is a serious problem called grade inflation and probably needs to be addressed in a separate post.

In my opinion, the purpose of my class is to prepare students for the appropriate class at the college level. If I am teaching physics, they should be able to continue their studies of physics in college and be successful (maybe even make an "A"!) Would I love to have all of my "precious ones" make 5's on the test? Of course! Since that won't ever happen, would I at least love to have them all pass with at least a 3? Yes! But honestly, I could care less about the test. Because the College Board says I have to teach to the test I do (which screwed us all this year since typically rotational motion is supposed to be about 20% of the test and my class is designed as such, but this year probably 50% of the test was rotational). But in reality, my underlying (sometimes not so subtle) goals are to increase student's problem solving abilities and prepare them for college.

That's it. If you are mad about that, too bad. However, I hope I have taught students something and given them a glimpse of what they will see in college. At least in their introductory classes. I think many students will be surprised at the amount of independent study will be required of them when they enter freshman-level classes. If memory serves (I only just graduated 3 short years ago and am currently working towards my master's) the professor doesn't spoon feed the information to students. They are supposed to be studying 2 hours for every hour they are in class each week. That means more than going over the notes the professor gave. In fact, most will give you their PowerPoint, so what's the use in taking notes, right? Maybe students should just read over the PowerPoint and then skip class? If I give the benefit of the doubt, and say students should only study an hour, not wait, a half hour for every hour they are in my class, then there should be about 8 hours per week of independent study going on. Oh and this does NOT include homework. Students are supposed to be studying that much in addition to the homework given by the instructor. I wonder how many of my students did that? Even on average? I dare say none.

I guess I didn't foster an environment that encouraged independent study. I think I started out doing pretty well at that, but then for some reason gave the idea that it would be okay just to get the notes in class, do the homework, and everything would be okay. The great thing about teaching is that there is always next year to change up what you are doing and try to make things better.

teacher vs. parent

No, this is not about a fight between a parent and a teacher. Maybe I need to think about that as a fundraiser for Physics and Astronomy Club. This is just a little reflection on the day.

Today I have been working as both teacher and parent. Instead of working on schoolwork, both for the classes I am teaching and for the classes I am taking, I have been working as a parent. Studying grades, visiting with students, i.e. having discussions about make-up work and test re-takes, you know all of the stuff that makes being a parent fun.

I must admit, sometimes it can be a sticky situation, since my children tell me one thing and then a colleagues tell me other things, meaning the stories don't always agree. Its difficult. In many ways I love having my kids here at school with me; I wouldn't want to change it. Then, in other ways, such as the one discussed here, it would be so much easier if they were simply a teacher at another district school.

Its really much easier to treat it like a normal parent would by just emailing the teacher. I could easily talk to them at lunch, but why ruin lunch with talk of business? There's enough of that going on at lunch anyway.

I'll just keep trying to be a teacher/parent and make the best of it. After all, what more can anyone ask? Its all I ask of my own kids and my own students.

Thanks for reading.

everyone loves a tesla coil

Wired.com posted a great video with Dr. Megavolt. Dr. Richards, as his alter-ego is known, lives a normal life as a particle physicist working on the AMANDA telescope, which interacts with neutrinos instead of visible light. In the video, Dr. Megavolt performs a some cool demos with his metal suit and Tesla Coil, reminiscent of Nikola Tesla's shows, way back in the day. It's a spectacular show and I believe I need to find out when he plans to come to the Science Museum of Oklahoma. I'm sure this type of demo leave a lasting impression on the viewer, especially when you consider that Tesla did his demos without a metal suit. No wonder people thought he was crazy and we now realize he was a genius. Probably mentally ill in some capacity, as well.


Check out the video and then go get out your Tesla Coil and light up some light bulbs or something! I can't wait to get mine out in class. The students never forget it.

What's the point, Mr. Bowie?

This was the question posed to me this week when we were discussion particle physics and the Large Hadron Collider in our classroom by an exceptionally bright student. She followed it up with "This just seems like an enormous waste of money."  I surely see her point. When you have friends at school who come from homes were there's not enough to eat or when they can't (or won't) keep the electric bill paid.


I imagine its also due (at least in part) to the idea students have that "everything that can be known, is".  As a student in high school, a person who has a constant inflow of information everyday, its easy to think the world is pretty well all figured out. I would say this is not the case, nor will it ever be. That doesn't mean we shouldn't stop questioning.  In fact, even if we, as scientists, think the world is all figured out, it would be a huge mistake to stop asking questions. According to Humphrey Davy: "Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer." It is worth mentioning that Davy was the mentor of Michael Faraday, who produced the theory that electrical force and the magnetic force are the same thing. This was the first Unified Theory of Physics, which laid the groundwork for all other unification theories in Physics. So in essence, we can thank Davy for everything we know about Physics, for without his encouragement of Faraday, we might not understand physics much better than we did back in the 1800's.


I think Albert Einstein said it best: "The important thing is not to stop questioning".  That is the point! That is why we do research. All of the technology we gain from particle physics research is just a bonus. The reason to do the research is for the knowledge gained.


Thanks for reading.

For the Love of Science!

Caution: this may be the most random, crazy post so far. Continue at your own risk. Don't say I didn't warn you.


Do you know anything about quantum mechanics? Well, that's good, because I don't really either. I once heard a quote by Richard Feynman: "If you think you understand quantum mechanics, you don't understand quantum mechanics" (insert dramatic pause for effect, followed by laughter).  Actually, I know some of the basics of quantum mechanics, but being able to recite something, is a far cry from actually understanding it.


In quantum mechanics, there is an interpretation of the mathematical formulas, which seems to indicate that the observer of anything, affects the object. You can do a little research on Schrödinger's cat to get a little better understanding. Basically, the way his thought experiment worked, the only way to observe whether the cat is alive or dead, would kill the cat. Now I've been thinking about this for a couple of years now and I am just beginning to be able to wrap my brain around it (albeit not very tightly). So if you don't get it on the first go around, don't sweat it. Keep thinking about it. If you don't accept this basic tenet of quantum mechanics, stop reading now, because what follows is based on your acceptance of a theory which has some experimental evidence. To understand that evidence, you'll need to have a basic understanding of Young's double-slit experiment.


I know! What's the point? Right? Actually, I do have one and it goes something like this: if observing the Universe changes the condition of the Universe, how in the world do we know the condition of anything? Most of this thought applies to quantum mechanics, but we could also apply it to, say, a classroom. How many teachers have asked a principal to come observe a particularly rowdy class, only to find when the principal enters the classroom, the students act in a completely different manner? Okay, I know its a stretch, but that's why they are called analogies.


I'm asking these questions, not because I want you to do some thinking, although that is part of my purpose. I'm asking these questions because I really want to know some answers.  I'm not sure what the answer to the question is. The problem with even asking the questions is that humanity is intrinsically connected to the very thing which they are trying to understand. Its kind of like walking by a mirror and thinking, "That's not really what I look like! Is it?" Based on Snell's, you are seeing an exact representation of yourself being reflected back from the mirror. For many of us, we have picture in our heads of what we look like. This is our reality, but once we actually observe our reality, we change it. (I can almost hear the crickets from my vantage point.)


As usual, I always understand things better after I process them through writing. Even though I didn't talk specifically about quantum entanglement, I think I understand it better than I used to.


Any thoughts? As always, thanks for reading.

In my classroom

Today we had a special speaker in our Pre-AP Physics class, Dr. Flera Rizatdinova (who is originally from Moscow and has a very strong Russian accent, which makes the talk much more interesting) from the Oklahoma State University Dept. of Physics. She is a scientist working on the ATLAS collaboration at the Large Hadron Collider. She shared some of the writing she has been doing for the DOE (which I mistakenly confused with the Dept. of Ed. initially) towards the end of her presentation. She was writing for them about the "benefits of particle physics research" which is a subject that arises frequently in my class. I hear something like "Mr. Bowie, isn't this just an enormous waste of money?"

Dr. Rizatdinova talked extensively about what the questions the LHC is trying to answer (see previous post). This was the deepest part of the presentation and was probably a little above level of my students (but if I don't set the bar high, they won't achieve as much, right?).  At the end, she took some questions which was really good for the students. I'm glad they have some opportunities to interact with college professors/scientists.

There wasn't really any ground-breaking material in her talk. I have been keeping up with the goings-on of the LHC recently and did some research over the summer with Dr. Rizatdinova, so much of this was a review for me. I'm not sure how the students will react to it, I'll try to get some feedback tomorrow.  I was simply excited about having a real, live scientist in my classroom and wanted to share the experience!

Why are we here?

Literally, why are we here? What was the cause of our existence? I'm not asking "what is the meaning of life?" I'm asking "what is the mechanism which causes our Universe to exist?" This is the goal of the LHC: to find the reason our Universe is ordered the way it is. Many talk about this as "The Hunt for the Higgs Boson". I learned today (via a special guest speaker in my classroom) the only particles needed to build our Universe are two types of quarks, electron neutrinos, and electrons. Wow.  Our physics research (worldwide) wants to know "why do these particles exist?" "What causes our these particles to exist?" "What is it that tells those particles to form?"


Talk about some big questions! Its a really difficult issue to wrap your brain around. In fact, I'll admit, I can't do it. I'm not sure I could ever be a part of the collaboration(s) which are trying to study this. Its some big picture thinking, and I'm not great at that. I try, in class, to impress on my students the level of thinking at which top scientists work. I admit freely to them that I am not capable of this level of thinking. I suspect that every now and then I will run across a student who is and I hope I can inspire them to choose an area of physics which suits their level of thinking.


I realize you came here to get an answer to this post, but I have only raised more questions. That is part of my job as a teacher, not to answer questions, but to encourage students to ask "the right questions" (see critical thinking).  So, have I done my job? Do you have more questions now than you did a minute ago? Go ask the right questions!

I was interviewed for the Yearbook

Below is an excerpt from an interview I did about how I assign projects in my class. I am different than other teachers in my school. I use a lot of technology, especially when it comes to projects for students.


When I assign projects, I use my discussion board http://tinyurl.com/bowies-board and have students sign up for the person/subject area. This way, there is no favoritism, no arguing, and no discussion about who gets what. It’s a first come, first served basis, so you have to be “on the ball” to get the person in which you are interested.


When we do a research project, students turn nothing in to me. We do it paperless. All students in my classes learn to contribute to a wiki. Each student, after choosing a person or subject area, creates a page in our class wiki and begins to add to that page. They add information, pictures, and videos. Whatever they want to make it their own. I encourage information synthesis. This is the process in which students research and choose information they feel is important, run it through their “worldview filter”, and put it on their wiki page. The address for our classroom wiki is http://thescienceclassroom.wikispaces.com. I have gotten a really good response from students on this project. We work on it for about 6 weeks, one day a week, with the rest of the work time done as homework, on their own.


I always request that students use technology when doing presentations. I have told them “I don’t come in and present information to you with a piece of cardboard, so you shouldn’t either”. I want students to recognize that the use of technology is required in college, so they need to start using it now. They will also encounter many different forms of technology when they finally get into their career, so the earlier they learn to use it, the better!

Who knew Science was so dangerous? (aka my 100th post)

I think its very appropriate this post is the 100th to make to my blog. So, without delay, let's get to what I want to share: a day in the life of Bowie's Physics classes.

my trip to the ERToday was a crazy day. It started out like any other. I was able to remember that I had duty, so I went down there and "did my duty", literally.  First block went of without a hitch. We covered some homework and then proceeded to an activity I learned at an AP conference. Students stand one meter apart, stopwatches in hand, while another student (or myself) walks/runs/jogs past. Since they have all started their stopwatches at the same time, they stop their watch when I pass them. We use this data to make a graph of position vs. time. We interpolate and extrapolate. We find the slope of the line, which just happens to be the velocity. I show them how you can have a negative velocity. Literally, the activity is everything that is right about physics. Unless, of course, something goes wrong.

Like today, during second block. Things went horribly wrong. I changed things up a bit. Problem  #1: we did the activity inside, normally we do this outside, like we did in 1st block. Problem  #2: I was the person doing the walking/running/jogging, normally a student or two are the ones doing the running/walking/jogging (I'm no spring chicken anymore). Problem #3: I was wearing my most comfortable shoes, which also happen to be the worst shoes in which to run. Note to self: either wear your running shoes, or wear a helmet next time!

Trials 1-4: I walked, I jogged, I walked really slow, I walked backwards (negative velocity). Everything was fine. Trial 5: I decided to move at a variable velocity by starting at a walk, increasing to a run, then slowing back to a walk. And then it happened: I ran out of room when I got to the part where I should have been slowing to a walk. I put the brakes on and started to stumble. I had no more breaks, lost all control, and fell. My only thought was, "Hmmmm, there's the greenhouse (made of metal and glass) right in front of me. I'm going to go straight through the glass. This is going to be really bad." I went down and negatively accelerated my head in a very short amount of time, thereby splitting the back of my ear open. I immediately said a few words, which were hopefully not heard by my students, and  got up to sit on the bench in front of the greenhouse. I realized later this was the same bench that just a second ago was in contact with my ribs. I put my hand to the side of my head and thought, "Okay, this isn't that bad. But boy does this hurt!"

I looked up at my students and said, "Why don't we just skip Trial 6?" I looked down at my hand, upon removing it from the side of my head and realized I might have a couple of small cuts there, since I noticed some blood, but not an enormous amount. No problem. "Could someone get me some tissue?" Strangely enough, only one or two students were actually moving. (I think they were stunned that I was that clumsy.) Tissue arrives.

We returned to the classroom, I got them started entering their data into the excel spreadsheet. Standard operating procedure for this activity. I walked over to the stunned look of my department head and asked would he mind keeping an eye on my class while I walked to the nurse to get a band-aid on these little cuts on my ear. Of course, that was after an abbreviated description of what had just transpired. I look in on my students and said, "I'll be back in a little bit. Mr. Stark is across the hall if you need someone."

I proceed to the nurse's office, all the while noticing there is now a considerable amount of blood on my tissue. Concern begins to set in. I arrived, again to the stunned look of the school nurse. I explain. She says, "Let me see!" I remove my hand and she informs me that I have a "gaping hole back here". I immediately go into shock. I begin to sweat. The color, all of the color, leaves my face. I don't feel so well. I lay down. She recommends that I go to an after hours clinic. Then, upon further inspection and a pupil exam, she thinks I may need to go to the emergency room. I really begin to panic a bit. I show panic by the above listed symptoms. My symptoms increase, which does nothing to alleviate my panic (or my symptoms).

Michelle (my wonderful and amazing wife) decides to come take me when the word ER is mentioned. Initially, Jessica (my exceptional daughter) was going to drive me. We decide against that. I talk the nurse. It is worth mentioning that Michelle is on pain killers for some dental work which she had done yesterday. She may be over the legal limit as far as narcotics and driving goes. We're not really sure and frankly don't want to know.

By this point, I have talked the nurse out of calling an ambulance. She rolls me out to the student pick-up area in the wheelchair. My symptoms begin to resurface as they had subsided after laying down for a bit. I feel worse. I really begin to feel terrible. I tell my caretakers, the nurse and Teri Voss (an asst. principal) that, "I'm just going lay down here on the ground". In front of the school. On the concrete. Is that weird? As I begin to get to the ground (on all fours) Michelle rounds the corner to pick me up. I'm sure her first thought upon seeing my condition, head wrapped bandage and all, was "Oh Lord! He's practically dying. I'm just in time to say goodbye!"

To make a long story (somewhat) short, we get to the hospital. The doctor reassures me that I do not have a nasty head trauma and that I will be fine. I just need, oh about 15 stitches. Yes. From the top of my ear to the bottom, I am stitched. My ER experience was quite jovial, once I realized I wasn't going to die or forget who Michelle is (at least not anytime soon). I twittered while there. I even twitpic'ed.

The doctor and nurses were very understanding and made my time almost enjoyable. It takes an amazing person to do their job. Next time you talk to a doctor or a nurse, thank them for me. After all, someone has to pick up the pieces after we are done doing dangerous science!


Update: Breaking Video!

I was able to get some video of my accident. Enjoy!

skepticism

I find, in my life experience, skepticism is healthy.  This trait can become a crutch or that which makes you a better scientist. I'm looking to encourage the latter. I try quite hard, in my classes, to teach my students to be skeptical of pretty much everything, save their beliefs. I teach that belief requires some measure of faith and that there is no room in The Science Classroom for faith. Don't get me wrong, I don't mean people of faith (read religious leanings) have no place in science; quite the contrary, I am not ashamed to tell students that I am a Christian.


My understanding of history is that Man first began looking around him at the Universe to look for God. They wanted to grasp the enormity of God and how He fits in the Grand Scheme (or how the Grand Scheme fits Him). So, I am NOT teaching students to be humanists or atheists or any other "anti-religion", although that may be a result of things that I teach.


What I try to do is get the point across that there is no place in the DOING of science for any kind of faith. There is a great quote from 1905 by Henri Poincaré in his book "Science and Hypothesis" which says: "Science is built up of facts, as a house is built of stones; but an accumulation of facts is no more a science than a heap of stones is a house." Its one of my favorite quotes and I think it says a lot about what science is and what it is not. Science is intrinsically a human endeavor. There WILL be errors because scientists are human. However, science is not simply a collection of facts (that's called wikipedia). I would define science as a collection of EVIDENCE and the interpretation of said evidence.


This is why I teach students to leave their beliefs at the door and search for the evidence. The human part comes along with the interpretation of that evidence. I can give them evidence that the Earth is flat. Just go outside and look at it and explain to me how you "know" Earth is round. I doubt any student (or reader) would "believe" me when I say the Earth is flat, but I also doubt they could give me evidence to the contrary. I could give students evidence that that Sun is revolving around that Earth and that all of the planets are following suit. In fact, the data collected in the early days of Astronomy (circa Tycho Brahe) would support that assertion even better than the data would support a Copernican (Sun centered) system. So, I ask you, which is correct? Is Earth at the center of the Solar System? Why do you think that? What evidence do you have? Why does the data support a geocentric instead of heliocentric solar system? (hint: check out Kepler's Laws for the answer).Image courtesy of EditorB on via http://www.flickr.com


My goal is to have students question everything they have been taught.  And by everything, I mean everything! We begin class in this way. I call it "the Nature of Science". We play some games, take some notes, and generally discuss what misconceptions or preconceived ideas they have about science. One of the tools I use is an open-source program called Stellarium. Its (obviously) free and is a great virtual planetarium for those days when the Sun makes looking at The Stars difficult. In case you are confused, that's everyday since we attend school only during a time when the Sun is above the horizon. What I do with this program is this: I ask the students what their ideas are about Astrology (not Astronomy, there's a big difference). Most, if not all, know their astrological sign but fail to realize what it means to be born under a certain sign. Some have ideas about positions of the planets and Sun, but don't know that being a Sagittarius means the Sun was (should have been) in that constellation on the day they are born. Enter Stellarium, rewind time to the date of their birth and show them (~97%) that they have been taught wrong their whole life! They are actually NOT the sign they thought, but the zodiac is shifted by one astrological symbol. I also introduce them to the much overlooked 13th astrological sign. Maybe you are learning something new?


Here is the crux of my thought: even after showing students that astrology is a bunch of bunk, many still go out of the classroom "believing" the horoscope they read in the newspaper (or now on the internet). Why is this? Why are we raising a generation (or two or three) who refuse to have any skepticism, even a healthy dose? Many teachers talk about students being "vessels to be filled". I disagree! They are full enough! (I won't say of what.) Some of what they "know" needs to be poured out and replaced with a whole new body of knowledge. Maybe its the teacher's fault. Maybe they have passed this "vessel perception" on to students so they sit there like sponges, soaking up everything coming out of whatever information giver they happen to be sitting before at a given time. We need to teach students to digest information.


Application. Analysis. Synthesis. Evaluation. These skills are at the top of Bloom's Taxonomy. Did these teachers who just fill students up miss those pedagogy classes? Isn't that what we were taught to teach? Come on educators! Get with it! You do your students a disservice when you just spout information AT students. We need more discrepant events! Only then will students begin to learn.

the downfall of humanity

I lost my wallet yesterday. Dumb. My fault. The only thing I can think of is that I pulled my keys out of my pocket and it pulled my wallet out, which consequently fell to the ground. This must have happened at the gas station yesterday morning. Yes, I should keep better control of my personal effects, but the fact remains that someone else found my wallet.


What would you do if you found a wallet with $6 and three credit cards and a debit card inside? Would you try to contact the person? They had my address. It was on my license. Recently I found a purse in the middle of the street. I returned it. As you can see from the title of this post, that was not the case with my wallet. They took the wallet, proceeded to a convenience store about 3 miles away and charged $100 worth of who-knows-what. This is extremely aggravating to me. Fortunately, I won't have to pay for the charges because I promptly reported the card lost which became stolen status thereafter.


Here are my questions. Feel free to comment. Why could the person or persons finding my personal stuff not return it? Why do you have to take something that doesn't belong to you at the expense of other's misfortune?


Now a tie in to science...I recently finished reading "Angels and Demons" by Dan Brown. Great book, very interesting, I highly recommend it, especially if you liked "The DaVinci Code". In "Angels and Demons", the question of whether science is too far ahead of morality is raised. In other words, can technology, as a result of science, police itself? Does it need the church to "help out" in that area? I guess I have to say "Yes!" Based on the events of the last day or so, people are basically not honest. Not good citizens. I know, I am generalizing here, but I am simply analyzing the evidence as it is presented to me. Give me more evidence to disprove my hypothesis. In case I haven't stated it, my hypothesis is this: people are bad and science is too far ahead of humanity for its own good. How can science be expected to "take care of itself" when people are at the root dishonest? I know this is a stretch, but how many of you have ever done something dishonest at someone else's expense? (I am point the finger at myself and will gladly admit I have been dishonest before.) If science is a human endeavor, which is one of it's basic tenets, how can it be expected to do the right thing when new technology is produced? Who even decides what is right? If we can create anti-matter (we can just not in the amounts in the fictional "Angels and Demons"), should we? If we can clone species (we can just not humans) should we? I posit that there is an argument for both sides. I could argue either question from either point of view and be reasonable.


Solution? I don't know. Maybe the church needs to do a better job of being relevant? I'm talking about the  church as a whole, I feel the church I attend IS relevant, otherwise I would look elsewhere. Maybe science needs to do a better job of policing itself? Maybe people need to put the needs of others before themselves? Maybe I need to maintain control of my stuff? Of course these are all good answers, but none will be the end-all solution (except maybe the last one for my immediate problems). I guess what I really needed here was a rant. Mission accomplished.

Teaching Science in the language of Mathematics

Those of you who have never taught math or science may not understand what we go through on a day to day basis here in the blurred world of science/math (aka Physics).  Let me give you some insight into my plight today while I was teaching centripetal acceleration.  I have students who are actually better at math than I am.  I know, I know.  I shouldn't be teaching physics if I don't know more about math than my students, but here we are!  I am learning so much everyday.


So, I had a student ask me a question like "where did the radians go?"  We were converting between tangential velocity and angular velocity and I was doing the unit conversion, just like I always do and I thought "Yeah!  Where DID the radians go?"  Honestly, I don't remember.  I told my students that, too.  "I really don't know."  I couldn't tell them.  I am sure there is some technical phrase like complementary adjacent angles that would perfectly describe what happens (I know its not complementary adjacent angles, so don't even go there); but I just had to tell them: "I don't know".  So, I read in the text.  I can't understand it.  I read again.  I am STILL not satisfied with the explanation to the extent that I am comfortable explaining it to students.


You may be saying about now..."So what happened Bowie?  Tell us! Tell us, please!"  Well, I will:  In walks another teacher who teaches Biology but knows a lot about units analysis (my term for it and I know Biology people do it too, I just don't think about them doing it.)  He and I start to talk about it and are still not entirely able to figure it out to our satisfaction.  Enter E.R. (his initials, not the Emergency Room), the brother of one of my best students from last year and proceeds to give us the vital piece of information required to connect the dots.  Voila!  I understand!  It was as if the light was turned on in my head.  It was something like what I imagine happens on a regular basis to my students when it all "comes together".  The vital piece was that I had never been taught (surely I didn't forget) what the definition of a radian is.  I just simply never bothered to find out! I never had a reason. Now I understand the "why" of the equation C=2πr for the circumference of a circle! I have known the how for a very long time.  I just never knew the why!


No big surprise that I learned something new.  My students never cease to amaze me by teaching me new stuff everyday.  I guess its just as amazing that I am willing to learn it.  Prayer: Lord please keep me willing to learn something new.


Thanks for reading.

This morning in physics...

Immediately following my previous blog post I saw this commercial. I mentioned to @mishelleyb that I found it interesting that there was no data given in the commercial. I found it remarkable that BK is so bold as to expect us to "swallow the Elephant whole". Burger King expects us to buy into the idea that 31 seconds of information is enough evidence to show that the Whopper "tastes" bettter than the Big Mac. My bias against the Big Mac notwithstanding, there is just not enough information in this short commercial to settle the issue. Besides, how do you measure taste anyway? BK's use of the commercial as a good argument against the Big Mac is something akin to using this rap video as a good argument to fund the LHC.

After watching the commercial, @mishelleyb came up with the brilliant idea of asking my students to analyze Burger King's experimental design. What was wrong with it? What was right with it? I also asked them to analyze the manner in which the data was presented. We had a very productive discussion during which my students found some flaws with Burger King's methods, in both design and presentation. We then went here and got some more information about their "cultural experiment" and revisited our tasks. We decided that while Burger King was not completely free from fault by serving us this ad, we at least got a view of a larger section of their data set and were able to mark a few of the issues we had with their methods off of the list.

It was very rewarding to collaborate with @mishelleyb, who teaches english, on a critical thinking assignment as well as discussing critical thinking with my students. As I told them, one of my goals in physics class is to make them better at analyzing evidence and sometimes just getting them to dig deep enough to find it. I'm afraid some of them may be dangerously close to being cynics and not accepting ANY evidence; but I do think I am at least pushing them towards "looking closer at evidence" before drawing a conclusion. Some of their cynical issues are mostly due to their maturity level; I think most of that will work itself out as they get older.

Overall, a rewarding day. Don't even get me started on Physical Science.
