Summer Reading

One of my goals this summer was to do more reading. I return to school is 21 days; so, I decided to capture what I’ve read so far since I probably won’t read too much more in the next few weeks.

I always fall behind on my magazines during the school year. So, every summer I skim the backlog and make notes for articles to reference later if they are relevant to a topic in class or a project to build. Over the years, I’ve reduced the number of magazines I faithfully read (or at least skim) to the three from which I learn the most: [Scientific American](http://www.scientificamerican.com/sciammag/), [MAKE](http://makezine.com/magazine/), and [The Physics Teacher](http://tpt.aapt.org/).

*The Grand Design* by Stephen Hawking and Leonard Mlodinow

I’ll read anything Hawking writes. After all, *A Brief History of Time* is what sparked my interested in physics and cosmology back in high school. I found *The Grand Design* interesting, enjoyable, and useful in unexpected ways. While the idea of M-Theory is interesting, I found the description of models and model-dependent realism excellent. In fact, I’m going to start AP Physics B with several quotes from the book on this topic as students really struggle to reconcile reality and models (“What is an electron, really?” “Are virtual particles actually present?” “How can light be both a wave and a particle?”). I also found their description of Feynman’s “sum over histories” particularly clear, and I hope that helps me teach quantum effects better next year.

*Black Holes and Baby Universes and Other Essays* by Stephen Hawking

Not having my fill of Hawking, I remembered this much older book that my brother had given to me. It was enjoyable to read Hawking’s essays that were written over a period of decades and reminded me of what an amazing period of time it has been, and continues to be, for the field of cosmology.

*Physics for Future Presidents* by Richard A. Muller

While I had read selected chapters from *Physics for Future Presidents*, I hadn’t read the entire book. This book is incredible in that it makes such an authentic connection between physics and the greatest technological, society, and political challenges that we have in a manner that is digestible by high school students. We are fortunate to have a classroom set and I hope we find more ways to utilize this book next year.

*Publishing with iBooks Author* by Nellie McKesson and Adam Witwer

I downloaded this [book for free](http://shop.oreilly.com/product/0636920025597.do) from O’Reilly. I wanted a quick read to familiarize myself with iBooks Author as I was writing [my AP Physics B review iBook](https://pedagoguepadawan.net/wp-content/uploads/pdfs/AP-Physics-B.pdf). If you are familiar with the iWork apps, you can figure out iBooks Author, but this ebook sped me through a few of the the app’s rough edges.

*Learning Java* by Patrick Niemeyer and Jonathan Knudsen

I will be teaching AP Computer Science for the first time this fall. I haven’t written anything in Java in a very long time. Whenever I need to learn a technology quickly, I turn to [O’Reilly](http://oreilly.com/). I admit that I only read the first twelve chapters. However, this book was perfect for refreshing my memory, filling in the missing pieces, and updating me on what has transpired over the past fifteen years.

*Five Easy Lessons* by Randall D. Knight

Dr. Knight was kind enough to send me a free copy of his book after a [Global Physics Department](http://globalphysicsdept.org/) meeting where he spoke. I started reading it shortly after receiving it, but it remained on the bedside table unopened as the semester became more hectic. There is so much wisdom and practical advice within its pages. I’ve made a note to remind myself when planning each unit next year to reference the appropriate chapter in *Five Easy Lessons* to see how I can improve my pedagogy. I still have a few more chapters to read before school starts.

*Squirrel Seeks Chipmunk* by David Sedaris

While all of the above books were enjoyable to read, occasionally it is good to read something not directly related to science or technology. I had received Sedaris’ latest book as a gift. It is uniquely Sedaris and a wonderful read.

*Marvel Comics: The Untold Story* by Sean Howe

This book isn’t released until October 9th, but I’ve read some great reviews already. I hope to make time to read it during the fall semester. Sean and I grew up reading comic books together and I can’t wait to see what he has written!

What have you read worth sharing this summer? Let me know!

AP Physics B Assessments

As I’ve [mentioned](https://pedagoguepadawan.net/193/preparing-for-new-ap-physics-b-course/), I’m spending some time this summer preparing for the AP Physics B course that we will be teaching for the first time this fall. I recently finished creating the assessments for this course.

With one exception (fluids multiple choice), all questions are from previous AP Physics B exams. Thanks to the handy indexes available from [Secure PGP](https://secure-pgp.wikispaces.com/), it was relatively easy to review relevant questions and problems and choose those I wanted.

While compiling the assessments, I refined the granularity of the units a bit.

Fall Semester

* Special Relativity
* Kinematics
* Statics and Dynamics
* Fluid Mechanics
* Work, Energy, Power
* Thermodynamics
* Linear Momentum
* Oscillations, Gravity, Waves
* Capstone Project

Spring Semester

* Electrostatics
* Electric Circuits
* Magnetic Fields and Electromagnetism
* Geometric Optics
* Physical Optics
* Particle Physics
* Atomic Physics and Quantum Effects
* Nuclear Physics
* Cosmology

For each unit, I compiled a quiz that contains representative free response problems to be used as a formative assessment. I then created an end-of-unit exam consisting of multiple choice and free response questions. The exam is intended to be completed in a 50-minute class period or less. To support the flavor of standards-based grading that I’m using in this class, I also created a reassessment consisting of multiple choice and free response questions. Scoring rubrics for all free response questions have also been compiled for each assessment.

I [uploaded](https://secure-pgp.wikispaces.com/PDF+and+Word+Problem+banks) the assessments as an archive for each semester to Secure PGP. I included the original Pages documents as well as versions exported as PDFs and Word files. I hope that some of you find these helpful. Please let me know if you find any mistakes.

Preparing for New AP Physics B Course

I will spend a lot of time this summer preparing for a new AP Physics B course. For most of the past five years, I’ve taught an Advanced Physics course which was a third semester of physics after Honors Physics that covered fluid dynamics, thermodynamics, and modern physics topics. This class wasn’t officially an AP Physics B class, but many students took the AP exam and were well prepared.

However, this new course replaces Advanced Physics, will be a two-semester course, and is open to students who have completed either Physics or Honors Physics. So, the students will have covered different topics and approached physics from different perspectives. For example, the Honors Physics class covers a superset of topics but the Physics class emphasizes the development and understanding of Models. Due to this diversity, and now being an official AP course, I’m taking the opportunity to develop new class materials and try a few new approaches.

Topic Sequence
===
We will briefly review or cover all AP Physics B topics in this course. Topics that are review will be used as opportunities to perform more sophisticated labs and explore new representations such as computational models. In addition, there are certain topics that I believe should be part of a college physics class and that are of great interest to students but are not part of the AP Physics B curriculum. We will cover those as well.

Fall Semester

* Special Relativity
* Kinematics
* Statics and Dynamics
* Fluid Mechanics
* Work, Energy, Power
* Thermodynamics
* Linear Momentum
* Oscillations and Gravity
* Waves
* Capstone Project

Spring Semester

* Electrostatics
* Electric Circuits
* Magnetic Fields
* Electromagnetism
* Geometric Optics
* Physical Optics
* Particle Physics
* Atomic Physics and Quantum Effects
* Nuclear Physics
* Cosmology

Components of Each Unit
===
I’m going to try a few new ideas in most units. Some of these are driven by methodologies that I have wanted to try for a while (e.g., computational modeling and peer instruction). Others are driven by new technologies available to my students (e.g., [Canvas](http://canvas.instructure.com/) and iPads).

Topic Summary

I’m currently writing an AP Physics B review guide as an iBook. I wanted a review guide tailored to my students’ experiences and the structure of the class. The review guide is organized by topic but focuses on the models applicable to each topic. In addition to a description of the relevant models, the graphical, mathematical, and diagrammatic representation of those models are included as appropriate. I want students to explore an additional representation of the models to reinforce their understanding and have been very impressed with John Burk’s [use of computational modeling](https://quantumprogress.wordpress.com/computational-modeling/). So, computation models developed using [physutil](https://per.gatech.edu/wiki/doku.php?id=projects:hscomp:physutil) and [VPython](http://www.vpython.org/webdoc/visual/VisualIntro.html) are also included. I hope to include the iBook (also as a PDF) as well as related videos and code snippets in an iTunesU course. I’ve been impressed with iBook Author so far and have exported the first chapter as a PDF.

Labs and Lab Notebooks

Since all students have already had a year of physics, I’m looking forward to doing some more sophisticated labs. Students will be creating electronic lab notebooks as portfolios in our new learning management system, [Canvas](http://canvas.instructure.com/). In addition, since we will have a class set of iPads available, we will be evaluating [Vernier’s](http://www.vernier.com/) new [LabQuest 2](http://www.vernier.com/products/interfaces/labq2/?lq2-home) and the [Connected Science System](http://www.vernier.com/products/interfaces/labq2/connected-science-system/).

Quizzes and Peer Instruction

I have been wanting to explore [peer instruction](http://blog.sciencegeekgirl.com/2012/03/16/ftep-effective-facilitation-of-clickers-workshop/) using clickers and I think the more conceptual questions would be a great fit and prepare students for the multiple choice portion of the AP exam. I found some wonderful existing clicker question at [OSU](http://www.physics.ohio-state.edu/~physedu/clicker/) and [CU Boulder](http://www.colorado.edu/physics/EducationIssues/cts/index.htm). I’m compiling quizzes from existing AP free-response questions and will use the scoring rubrics to provide formative feedback to prepare students for the free response portion of the AP exam.

Exams

[Secure Pretty Good Physics (Secure PGP)](https://secure-pgp.wikispaces.com/) is a great resource for AP Physics teachers. Other teachers have indexed questions by topic which makes creating new exams much easier. I’m compiling an exam and a reassessment exam for each unit based on existing AP multiple choice and free response questions. I plan to post these, along with the quizzes, to Secure PGP when I’m done.

Standards-Based Assessment and Reporting

I’m using a slightly modified version of the SBAR structure that we’ve been using in Honors Physics. The biggest change is that assessments will be scored on a five-point scale, like the AP exam itself. This is a small change for those students familiar with Physics’ four-point scale, but a more significant change for those students familiar with Honors Physics’ mastery system. Another significant change is the granularity of standards. Due to the integrated nature of the AP exam, standards will be very broad, usually one standard for each unit. All of the details of the SBAR structure are enumerated in the class syllabus.

Download (PDF, 62KB)

I hope some of you who are also teaching AP Physics B find something here of use. I know that the work that other teachers have done is incredibly helpful as I prepare for this new course. I plan to share pretty much everything I compile either here or on Secure PGP; so, please stay tuned or ask if I forget to post something.

Inspiring Younger Students with Near-Space Balloons

On Sunday, my school’s Physics Club launched their third annual near-space balloon. It was a fantastic success this year. Our first year, we simply focused on launching and retrieving our payload with photos and videos. [Last year](https://pedagoguepadawan.net/60/nearspaceballoon/), we focused on gathering data (temperature, pressure, radiation). This year, we focused on inspiring younger students in our school district.

High school students in Physics Club contacted former teachers at the elementary and middle schools and asked if they would be interested in collaborating on the design and construction of an experiment to be launched to the edge of space. Four schools accepted the challenge. The high school students visited the classroom to introduce the project and followed up with additional visits in person or via video conferencing.

The ideas generated by the younger scientists were amazing. One elementary classroom wanted to see what would happen to Jello and popcorn throughout the flight. Another explored the effect of pressure on Peeps and sealed rubber duckies containing water or air. One classroom painted craft sticks with nail polish that changes color based on temperature and UV radiation. Another put condiment packages in a payload and filmed them throughout the launch. The final experiment was testing how a battery powered light changes throughout the flight.

We launched from a new location this year to provide a greater buffer between the predicted landing zone and the no-fly zone around Chicago due to the NATO summit. We didn’t want a F-16 shooting down our experiments. We experienced a near-failure due to under filling the 3000-g balloon, but we recovered and had a successful launch. Due to a grant we received from our district’s educational foundation, we were able to purchase new equipment so we could track the balloon throughout the flight. We installed an APRS transmitter on the balloon that sends GPS coordinates over the HAM radio band. This signal is picked up by repeater stations throughout the area as well as by our own rig which we interfaced to a computer to map the location of the balloon. It was quite a different dynamic this year as we knew the location of the balloon every minute. We hung out in a McDonalds and tracked the balloon; the whole group cheered when we passed 100,000 feet. You can export the tracking data from [aprs.fi](http://aprs.fi/) and display it in Google Earth.

Flight path

The balloon reached a maximum altitude of 105,330 feet (~20 miles) and the flight lasted 2 hours and 34 minutes. Here is the video of the flight:

We also created [an album](https://vimeo.com/album/1949045) that contains videos of the preparation for the launch and the analysis of each school’s experiment after the launch.

This year’s project would not have been possible without the support and efforts of many people. The [Naperville Education Foundation](http://www.nef203.org/), [Space for All](http://spaceforall.org/), [Adler Planetarium](http://www.adlerplanetarium.org/investigate/participate/farhorizons/?searchterm=horizons), and W9BKO. In addition, several science teachers from my school contributed and alumni with much needed expertise assisted. Finally, the classroom teachers who accepted the challenge of this project late in the school year made it an amazing experience for all of us.

If you are interested in launching a near-space balloon and have questions, please don’t hesitate to contact me. My colleague and I have [presented our tips](https://pedagoguepadawan.net/170/near-space-ballooning-county-institute-session/) for launching your own near-space ballon which you may also find helpful.

SBAR and Mastery Student Survey

I previously wrote about my [challenges with my Honors Physics class](https://pedagoguepadawan.net/177/help-sbar-challenges/) this year. I received several comments from other teachers which influenced the survey I administered to students this past Friday. While my colleague and I still need to analyze all the data, reflect on the semester, and decide what changes we will make for next year; I thought I’d share some of the more interesting feedback that we received.

**Homework**

The biggest change that we made this spring semester is that we [no longer provided credit for homework](https://pedagoguepadawan.net/166/no-more-credit-for-homework/). This was motivated by our experience that students weren’t developing good problem solving techniques and that he homework was really just for practice. This change was the most frequently commented on by students. On the survey, only a third of students agreed with the statement that they complete their homework before the unit exam, but 90% said that they would if it directly affected their grade. In addition, half of students agree with the statement that they complete the homework only because it is required before doing 2nd tries (our reassessment opportunity offered before and after school once a week for two weeks following the summative exam). However, 77% of students agree with the statement that they write out the complete solutions as opposed to just answers. So, while students are developing better problem solving techniques, they aren’t doing their homework.

The reasons for this are captured best by the feedback provided by a couple of students:


I liked the way the system worked first semester much better. Even though webassign was normally a stressful night before rush, I always felt significantly moer prepared after completing it and knowing that it was going to influence my grade if I didn’t do it was just enough motivation to complete it each time. This semester, now that there is no required prep before the exam, I find myself preparing less, which I know is ultimately my own responsibility. I know many students are probably in the same situation though, being motivated by hw completion grades. I think requiring prep before first assessments would also help to lower the percent of people who need second tries since they are more prepared for the first try.


I personally think that you should require the graded webassign before the tests, much like first semester. For me, I typically read the book and do a few practice problems before the exam, but I often don’t have enough time to study adequately (my biggest problem this year). I just don’t have enough time to do everything (school work in general) so I prioritize, and graded assignments take priority. Spending time working on assignments is less time for sleeping at night, so very often the most studing I do is a reading of the entire section during lunch. If webassign was graded, I would do it.”

These comments illustrate that students are aware that they need the practice, but feel unable to do so with out the threat of losing points. These comments are indicative of a much broader issue. Is the problem that we don’t motivate students to do homework by awarding credit or that other classes do? If no one awarded points for homework, then students could decide what to do based on what would help them most.

**Preparing for Initial Assessment**

The results of the survey and the comments shared by students demonstrate that the homework change is one of the factors contributing to the lack of preparation for the initial assessment. In addition, a couple of other questions on the survey reinforced my concern.

Only about half of students expect to master the standards on the unit exam and half feel lucky when they do master a standard. 88% of students, compared to 63% of students, say they prepare sufficiently for the second assessment compared to the original assessment.

[Todd Zimmerman](http://talkingphysics.wordpress.com/) and [Kelly O’Shea](http://kellyoshea.wordpress.com/) both suggested that additional formative assessments were needed. I added questions to the survey to solicit feedback on this idea. While only 43% of students want more homework before the initial summative assessment, 68% of students want quizzes with feedback before the unit exam. I think the survey results support [Josh Gates’](http://www.twitlonger.com/show/h1fa8l) idea of providing initial formative assessments for feedback not grades. While there is little to no difference between these assessments and homework, simply presenting it in a different way results in very different reactions in students. So, Todd, Josh, and Kelly’s ideas definitely resonated with students. The challenge will be for my colleague and I to find time to create, administer, and provide feedback on these formative assessments.

**Standards Based Assessment and Reporting and Mastery Learning**

My colleague and I started applying SBAR and mastery learning three years ago for a variety of reasons. The primary one was to help students focus on learning rather than grades and, as a result, better retain the concepts and have less stress.

75% of students agreed with the statement that having the standards enumerated help them prepare for the exam and 62% of students agree with the statement that the mastery system helps them focus more on learning and understanding and less on points and grades. That said, 53% of students say they still focus on their grade in honors physics as much as they do in traditional classes. In addition, while 75% of students said they take 2nd tries to improve understanding, 94% of students said they take them to improve their grade. In general, Honors Physics students are extremely grade conscious. However, in terms of stress, 91% of students find exams less stressful knowing 2nd tries are available.

Another concern that I had was that students weren’t doing their best work but, instead, were putting forth the effort to just barely master the standard. Students disagreed with this assertion. 82% of students said they do the best they can when completing an assignment and only 15% say they do the minimum to achieve mastery. Perhaps this concern of mine was due more to end-of-year malaise than reality.

Most students appreciate the benefits of standards-based assessment and reporting and mastery learning. To provide some context, the initial summative assessment usually consists of a multiple choice portion for some standards and a problem-solving portion for others. On the multiple-choice portion, students can usually miss one or two questions and still demonstrate mastery. On the free response portion, students can make non-critical errors and still demonstrate mastery. Here are some of their comments:


I like the Honors Physics standards system, but sometimes the standards do hurt my grade (if I miss two questions out of 7, it is a 0% instead of a 72%). I really appreciate the second tries for standards because of this. I also feel that the standards system forces students to retain what they learn and helps them be more prepared for the final.


The second tries are extremely beneficial to students because it allows students to relearn a target, which I believe reinforces and strengthens the learning from a topic. I remember second try targets much better than other targets.


I feel as if the class is well oriented in that it helps people to focus more on the concepts rather than having to worry about their grade. It really helps a lot more in the long run.


I honestly loved physics both semesters, second especially, and i actually found that i it was required for me to understand the material by doing the work, and i enjoy that. Not all classes need you to understand, a lot just ask for you to memorize stuff. Also, i heard that this is the type of learning you need for college so this will probably help.


I feel like, while the mastery system is sometimes problematic, it really helps to ease the stress that I have while taking each exam. Knowing that by making one silly mistake, I can still get 100% in a category allows me to stop stressing about every single little thing during tests, which also helps me to focus. It is inconvenient when I don’t master a standard, but I feel like the 0% that results from it furthers my determination to clarify that standard and thus improve my grade during the 2nd tries.


I think that however much you put into the class is what you get. Like all other classes, the advantage is in taking the intiative, regardless of the grading system. I feel the standards system is a keeper though, because as you said it eliminates the hesitance for each individual point and allows the student to focus on the big picture. VURY NICE.


With grades being administered on a pretty consistant schedule, I find that I care less about my grade for this class. The use of standards makes me feel accountable for mastering a topic. That is to say, I don’t feel good if I master a target out of luck on an exam. I think other courses’ grading systems could take the honors physics model! Physics was a pleasure!

However, some students definitely do not like the mastery learning system. While they don’t object to the principles of SBAR, the binary nature of the mastery learning system drives them crazy.


The Mastery system is extremely stressful, because it is possible to miss 4 questions across two standards and fail an exam, while it is also possible to miss 4 question across 4 standards and receive a 100%. This system would be great if it was not tied to the letter grade system, but because it is, it’s extremely detrimental to report cards. (Which do matter, regardless of understanding or not.)

I may use this quote in my introduction of mastery learning next year. I don’t expect every student to agree with my philosophy that the grade for the course should reflect true understanding of a concept regardless of the effort exerted to almost understand it. However, I want every student to understand my perspective.

**Additional Challenges**

Unfortunately, cheating is always a concern of my colleague and I. We asked several questions on the survey about cheating and, unfortunately, I was surprised when 59% of students agreed with the statement that other students cheat on 2nd tries and only half of students disagreed with the statement that they feel pressure from their peers to tell them what is on the exam or 2nd tries.

As in the case with the additional formative assessments, the challenge will be for my colleague and I to find the time to address this issue. However, we have to ask ourselves how to spend our very limited time. Do we spend it to thwart those students who are trying to cheat or do we spent it to help those students who are trying to learn?

**What’s Next?**

I had discussions with several students who suggested that completing homework should not be graded but should be required before the initial summative assessment in order to earn the opportunity for a second summative assessment. This is the policy of another science class and students like that it motivates them to complete the homework before the initial assessment. Personally, this doesn’t ring true for my philosophy.

My colleague has what may be a great solution. He wants to focus on lab notebooks next year. He is proposing that students are permitted to use their lab notebooks, which may contain observations from lab activities and homework problems, on the initial summative assessment and perhaps not on the secondary summative assessments. This may provide sufficient motivation for students to complete the practice that they need before the initial assessment without requiring all students to complete the same amount of practice or penalizing those who don’t complete the practice.

I hope to meet with my Assistant Principal and hear the motivation behind the policy to not allow reassessments unless a student earns less than an 80% on an exam and to cap that reassessment at 80%. I hope to side step this policy entirely, but I am curious as to the motivation behind it. I also want to share these results and our ideas for next year.

We will have a new LMS next year and perhaps that will provide a mechanism to offer more formative assessments and feedback before the summative assessment.

This summer, my colleague and I will sit on one of our decks and figure out what to change for next year. I’m now more confident that we can continue to pursue [our goals](https://pedagoguepadawan.net/37/whysbg/) without taking steps backward.

Reflection and Refraction Activities

We are currently in the midst of the geometric optics unit in my honors physics class and just finished waves, which includes reflection and refraction, in my regular physics class.

My colleagues and I have developed a series of reflection and refraction activities that provide a shared experience that can be leveraged as we explore reflection and refraction of light. In addition, students find these activities engaging and they generate a lot of great questions.

I hope you find a new activity that you can use in class.

Here are the handouts.

I don’t have photos of the reflection activities, but I think they are pretty self explanatory. If not, ask, and I’ll clarify.

I do have photos of the refraction activities. I need to give credit for the first activity which is a recreation of an AAPT Photo Content winner from a few years ago.

The Physics of Art and the Art of Physics

At the end of the year, we make time for a final project in our General Physics class. We purposefully define a very nebulous standard to provide the ultimate flexibility in this project:


Understand the relationships among science, technology, and society in historical and contemporary contexts.

Last year, due to the topical nature of the Fukushima nuclear disaster, we choose the [topic of nuclear energy](https://pedagoguepadawan.net/45/nuclearphysicsproject/).

This year, a colleague had the fantastic idea to choose a cross-discipline topic: the Physics of Art. I suggested extending the topic to include the Art of Physics. This topic: The Physics of Art and the Art of Physics will allow students to explore one of their passions and explore the physics and artistic elements of that passion. I expect some fantastic projects.

My colleague created the following introduction document:

Download (PDF, 55KB)

Another created the rubic:

Download (PDF, 50KB)

I created an exemplar:

Download (PDF, 251KB)

I’m using the new (at least to me) feature of [WikiSpaces](http://www.wikispaces.com/) where I can define a project and teams. Each class is its own team, but they can view and comment on other classes’ projects. This will make maintenance of the wiki manageable over multiple years.

I’ll share some of my favorites and let everyone know how this year’s project goes. I have high expectations!

Help! SBAR Challenges!

My colleague and I have been using standards-based assessment and reporting (SBAR) (a.k.a. standards based grading (SBG)) and a mastery learning methodology for the past three years. We have been very pleased with the results and have continued to evaluate and improve our methodology each year. However, this semester, it appears that the students aren’t drinking the kool-aid. I need some advice.

We are planning on administering an anonymous survey as well as having a class discussion on the topic of SBAR, learning, and assessment. I also plan to talk privately with various students. However, I wanted to solicit the advice from the larger SBAR community first since I expect that will shape the survey and direction of the conversation.

The problems this semester are that students are doing worse on initial assessments and the quality of work has deteriorated. To be fair, this doesn’t apply to every single student, but it does appear to be an overall trend. While I’m not sure of the reasons behind this change and I hope that the survey, class discussion, and individual discussions provide some clarity, I have a hypothesis. I believe that there has been a change in attitude this semester compared to the previous five.

In past semesters, many students would have the following attitude towards class: learn the material as well as possible throughout the unit, do some of the homework, and try to master every standard on the initial exam. If they didn’t master a few standards, they would complete extra practice and take advantage of a reassessment outside of class. These reassessments were best to be avoided, however, since they required extra work and time outside of class.

This semester, I believe many students have the following attitude towards class: try to learn the material only based on in-class activities, do nothing outside of class, and attempt the initial exam. They expect to have to reassess every standard; so, any that they happen to master on the initial exam is considered a fortunate bonus. They then prepare the required extra practice and take advantage of the reassessment outside of class. In addition, since they only have to master a standard, do the bare minimum amount of work or quality of work to meet that expectation.

I still believe our methodology is philosophically sound. However, I fear that this deferred effort approach will result in less understanding and less retention. In addition, this bare minimum approach leads to sloppy and careless work and poor habits. This is not okay regardless of how sound the philosophy is.

I’m considering a couple of changes. One, abandon the mastery system for a 1-5 scale like what I use with my AP-level class. While this allows for more differentiation in terms of quality of student work and depth of understanding, it feels like such a huge step backward in terms of trying to de-emphasize grades. Two, adopt a cap for reassessments. My school is pushing an 80% cap for reassessments. Only students who score less than 80% are eligible to reassess. In addition, the maximum score on a reassessment will be an 80%. While this may motivate students to develop their understanding and practice before the initial assessment, it seems to contradict the very foundation of SBAR.

Perhaps even more importantly that understanding the change in attitude, I’m not sure what has precipitated this change. What is different this semester compared to the previous five? How am I, my student, or my school different?

It is all somewhat depressing since I felt that we really had created something special that was meeting the [goals I set for my students](https://pedagoguepadawan.net/37/whysbg/). Instead, this semester, I feel that our fragile ecosystem has been shattered and I’m not sure we can recover.

Where I’ve Been for Three Months

You may have noticed that I’ve been mostly absent from the intertubes for the past three months. This happens every year from January through March. Why? It was all for a girl named Lucy:

A bit over four years ago, with no prior notice, I was asked by a student I didn’t know to show up in a meeting room at school to discuss a robotics program. A couple of hours later, four students and four teachers had signed the paperwork to found FIRST Team 3061 and participate in the FIRST Robotics Competition.

We just completed our fourth season. It was an amazing year. We rebranded the team with a new logo and a new name: [Huskie Robotics](http://team3061.org/). We secured major funding from Navistar, the Motorola Solutions Foundation, and our high school Boosters Club. We partnered with [Create, Cut, and Invent](http://www.createcutinvent.com/) for fabrication. We had several dedicated mentors working with the students. With our corporate support, we were able to attend two regional competitions. Two weeks ago we participated in the Lake Superior Regional. We didn’t make the elimination rounds, but we discovered and fixed several issues, refined our strategy, and got a lot of practice. This weekend, we participated in the Midwest Regional with teams from the midwest as well as Arkansas and Texas.

We finished the qualification matches with a 9-2 record and ranked 10th! During the alliance selection process where the top teams choose their alliance partners for the elimination matches, we ended up as the captain of the 7th alliance! Thanks to our scouting reports, we were able to make wise decisions and select teams that were under-ranked and overlooked by others. Teams 1710 (Ravonics Revolution) and 1781 (Electric Eagles) graciously accepted our invitation to join our alliance.

As the 7th ranked alliance, we met the #2 ranked alliance, consisting of teams 1625 (Winnovation), 2949 (Pwnage), and 3135 (Robotic Colonels). in the quarterfinals. We won the first match 42-36 and won the second match 38-37 to advance to the semifinals! Both matches were won in the final seconds with all alliance members contributing to the victory.

We met the #3 seed of teams 111 (Wildstang), 71 (Team Hammond), 2151 (Monty Pythons). We lost the first match 35-53. It was actually very close as our alliance almost completed a 20-point double bridge balance in the final seconds. Our alliance had some bad luck in our next match as both our alliance partners had mechanical issues which disabled their robots from driving. We made the best of the situation, scored several baskets during the teleoperated phase, and balanced on the bridge on our own. We ended up losing 38-44. We held our own against some of the most veteran teams in all of FRC as Wildstang has won three national championships and Team Hammond has won four!

While competing as a semifinalist is the most success we have ever had at a regional competition, the team had more accolades coming our way. During the final awards ceremony, Huskie Robotics was awarded the Gracious Professionalism award for outstanding assistance to other teams both on and off the field. FIRST describes Gracious Professionalism as:


Gracious Professionalism is part of the ethos of FIRST. It’s a way of doing things that encourages high-quality work, emphasizes the value of others, and respects individuals and the community.


With Gracious Professionalism, fierce competition and mutual gain are not separate notions. Gracious professionals learn and compete like crazy, but treat one another with respect and kindness in the process. They avoid treating anyone like losers. No chest thumping tough talk, but no sticky-sweet platitudes either. Knowledge, competition, and empathy are comfortably blended.


In the long run, Gracious Professionalism is part of pursuing a meaningful life. One can add to society and enjoy the satisfaction of knowing one has acted with integrity and sensitivity.

We helped several teams by giving them parts and materials and by helping them program their robot. Several team members spent most of the competition assisting a particular rookie team who only had one teacher and one student present. We helped this team rewire their robot, get their ball collector and shooter to be functional, pass inspection, and write all their software. In addition, two members of our team stepped in as field players for this team! Their efforts did not go unnoticed and the judges commented that “while you usually want at St. Bernard to come and rescue you, they would prefer a Huskie!”

None of this comes easily. As one of the three teachers mentoring the team, I put almost everything else in my life on hold for three months. I’ve missed every [Global Physics Department Meeting](http://globalphysicsdept.posterous.com/#!/) this year because I’m at school until 9 pm on Wednesdays with the team. Every Saturday that I’m not at a Science Olympiad Event or a QuarkNet Particle Physics Masterclass at Fermilab, I’m at school all day with the team. I sleep little and spend my nights on the phone or online researching, planning, purchasing, debating, or counseling. I do all of this because I believe that what these students get out this program is the most inspirational, valuable, and rewarding experience of their high school careers. They are inspired to pursue STEM-related careers; they gain the confidence that they can create something remarkable; they learn to lead through influence rather than authority; they embody the spirit of Gracious Professionalism. Every student on the team has the opportunity to go pro in this sport.

If you’ve never witnessed a FIRST Robotics Competition, [go see one](http://www.usfirst.org/roboticsprograms/frc/regional-events); you still have three weeks. [Volunteer](http://www.usfirst.org/community/volunteers/register-to-volunteer) to help a local team or event. Or, if you are just crazy enough and I know that many of you are, start your own FIRST Robotics team.

Near-Space Ballooning County Institute Session

My colleague and I, who advise our school’s Physics Club, volunteered to share our our experiences over the past two years designing, launching, and retrieving near-space balloons. Last year’s balloon reached an altitude of over 100,000 feet and captured amazing photos, video, and temperature and radiation data. We discussed the technologies involved in near-space ballooning such as GPS receivers, microcontrollers, programmable cameras, and sensors. We also shared different approaches to designing near-space balloons that fit a variety of budgets. Finally, we discussed this year’s project in which younger students are designing and building experiments to be launched as part of this spring’s balloon launch.

The slides we presented are below as is our handout with links to various resources. This is a fantastic project for a group of students to tackle. If you decide to try to launch a balloon, please feel free to contact me.
