Call for jurors: 2024 Conceptual Physics Tournament, on May 19. We pay $100.

In my school's conceptual physics program, we give cumulative written tests after the first and second trimesters.  In lieu of a final exam*, we are once again running the Woodberry Forest Conceptual Physics Tournament!  This is a competition for 9th graders, to be held at 1:00 on Sunday May 19 2024.  We've done this before, including the last two years after a pandemic-enforced break.  We're happy to be back to annual.

*No, to be clear to all, we're not giving an A to the winner and an F to the person in last place.  That's silly.  We're just having a fun, competitive tournament, to determine a winner.  Jurors engage in discussion and conversation with participants about their problems.  Jurors then award scores and write comments for the participants; jurors aren't assigning grades!

How does this tournament work?

On May 1, I will reveal a slate of three problems to the 64 participants.  These problems will be in the style of AP Physics 1 "paragraph response" questions.  Except, rather than just answer in a paragraph, the students will spend the month of May setting up experiments to provide evidence for their answers. By tournament time, each student will be expected to be prepared to discuss the solution to two of the three problems, with both theoretical and experimental support.

At the tournament, each student will participate in two "physics fights."  Think of these physics fights like a miniature version of a graduate thesis defense.  Students will have a strict limit of two minutes to present their solution to a group of two or three jurors, who then will engage each student in conversation about the problem for five minutes.  The students are evaluated by the jurors not only on the quality of their solution, but also on their ability to discuss the solution, to confidently hold a conversation with the jury.

Importantly, jurors are explicitly instructed on their primary role - to find out how much the students DO know, not merely to expose what they don't know.  

How do the students prepare?

Starting on May 1, all conceptual physics classes the rest of the year will be devoted to tournament preparation.  They'll work together to set up experiments in class, they'll be assigned to write up their solution as homework, they'll practice presenting.  They'll get intense instruction and guidance from the conceptual physics teachers, from their peers in the AP classes, from those who've been through this tournament before.

We need jurors.

The key, I think, to any class project is external assessment.  I and the other conceptual physics teachers will play the role of coach and advocate, always encouraging and helping the students to deepen their understanding of the problems and to improve their presentations.  Our relationship will be purely supportive, enthusiastic, positive.  

We can't then turn around and grill these same students as examiners!  That'd be like our football team's coaching staff refereeing the state finals.  Even -- especially -- if their officiating were fair, the coach-student relationship, both in before and after the game, would be irrevocably compromised.

So we need jurors.  We can pay.

Would you like to come to Woodberry on May 19 to be a juror?  We'd ask you to arrive at 11:30.  We'll have a meeting of all jurors in our beautiful dining hall over lunch.  

Then we'll ask you to be a juror for a couple of hours' worth of physics fights.  You'll be partnered with several other examiners over the course of the afternoon, getting to know a diverse set of fun folks from all over.  When all students have presented their two physics fights (to two separate juries), we'll gather the jurors for conversation, coffee, snacks, and their paycheck.

In any case, our goal is to be done by 3:30, or possibly 4:00 if there are logistical issues.  No later -- our students will be attending the final seated meal with their advisors that night followed by study hall, so we can't run late.

We will pay you $100 plus lunch for your time.  (If you're coming from more than a few hours away, we can put you up on campus on Saturday or Sunday night - please let me know if you're interested in this option!) I think you'd find that the camaraderie among the jurors and the engagement with the students will make the trip worthwhile.

Who's eligible as an juror?

Anyone who has passed a college-level physics class.  This includes alumni of your advanced physics class, even if they're still juniors or seniors in high school - we've had several teachers bring a caravan of students, and they've had an awesome time.  We've had local college or graduate students on juries, we've had parents, alumni, colleagues who teach other subjects, grandparents, friends... Anyone willing to engage in conversation about physics at the high school level, as long as you can recognize good and bad physics, we'd love to have you.  We are looking for a diverse juror pool, which especially includes diversity in age - truly, we want folks in their teens as well as folks in their 70s, and everywhere in between. When I ran the USIYPT, I found the mixture of undergraduate / graduate / professor / high school teacher / industrial physicist / retired physicist on the juror panel allowed some amazing relationships to develop.  I'd love to create a similar vibe here.

How can I sign up?

Send me an email via greg dot jacobs at woodberry dot org.  I'll send you more information, including the three problems, and our current draft of the scoring rubric.

We would like to get 45 jurors - pretty much the first 45 who sign up.  I can't wait to see some blog readers!  I'll even introduce you and your students to my pet hippopotamus, Edna.  :-)

April 8 2024: Free AP Physics 1 exam prep live show! (Archive link available)

McGraw-Hill, publisher of the 5 Steps to a 5 AP prep book series, is sponsoring a free live physics show for students and teachers.  I'll be presenting from my lab on Monday April 8, from 3:30-5:00pm eastern time.

All are welcome!  The way to join is, teachers (preferably) should "register" for free at this link.  They won't ask for you to make a username and password, nor to receive marketing emails.  Just give your last name and email.  Then, you'll get a message with the link to join - a link you can share with all your students, colleagues, friends, whoever.*

*McGraw-Hill would prefer not to be in the business of collecting student emails.  So they ask for a teacher's email, and ask the teacher to share the link.  They're trying to be entirely above board here!  There's no sneaky agenda to get your personal info!   The only agenda is, they want your students to buy the 5 Steps book.  :-)

I haven't planned the show yet, other than the general vibe, which will be similar to my 2020 live shows or my AP classroom videos (for Physics 1, units 2 and 3).  My pet hippopotamus Edna is excited for the event, and no doubt will make an appearance.

Do you have any requests?  My initial brainstorms are perhaps to set up experiments based on the 2023 P1 exam questions 1 and 2 - about harmonic motion, and a cart rolling down a ramp.  And I'll definitely leave plenty of time for improv, in which Bob the master of ceremonies will read the chat, and relay questions or requests to me.  However, I'm open to all sorts of suggestions now.  Post in the comments, or contact me via email or Bluesky!  I can do a lot in a 90 minute live show.  Tell me what you and/or your students want to see, and I'll try to make it happen!

And spread the word.  Last year, this Physics 1 live show was the best-attended of all of the subjects they offered... by a factor of about 20.  Let's keep that momentum going!  See you on April 8.

AP Summer Institutes 2024 - will the new exam content and structure be discussed?

Of course it will!  

I'm doing several online and in-person P1 institutes in summer 2024 - see the sidebar to the left for details.  Please sign up!  The institute will certainly discuss content and structure changes for the 2025 exams.

What, specifically, will we do?

  • We will do a number of fluids demonstrations and lab activities, including all three major fluids topics.
  • We will do demonstrations with the three minor content changes in P1: parallel axis theorem, quantitative understanding of elliptical orbits, and center of mass location.
  • We will discuss the new exam format - though I will emphasize that in P1, preparing students for the 2025 exam format looks exactly like preparing students for the 2015-2024 exam format.
Of course, the institute will still do all the AP Summer Institute things that you expect.  I'll give an overview of the AP program, the course audit, and AP classroom.  Much more interestingly and importantly, I'll discuss give you access to my course files, problem sets, laboratory activities, quizzes, tests, and a day-by-day planner.  Teachers new to AP Physics 1 can use these verbatim to get themselves started; veterans can use the materials to supplement and inform what they already do well.

The highlight of the in-person institutes is the "studio time" in lab on the final day, in which we all work together to set up and develop laboratory exercises based on released AP questions.  You'll come away with a dozen or more pre-tested new lab ideas!  In the online institutes, which are broadcast live from my actual classroom, we'll instead do "improv time" - challenge me to set up an experiment, or to show how I use demonstrations to teach any topic on the exam.
