Invited Talk: “Changes in the Teaching of Introductory Physics at Stanford” Chaya Nanavati or Stanford University
Chaya discussed the existing structure that has an instructor that leads lectures and has Head TAs, Discussion TAs and Lab TAs that assist the smaller groups. Often we encounter several barriers to change: Administration or Colleagues are often resistant to change and need convincing, materials and time are necessary for change. She suggests using the already developed resources from Maryland University, Harvard, CU Boulder, etc. on group work and student-centered learning. Eric Mazur has lots of resources and evidence that interactive engagement increases the post-test gain on the Force Concept Inventory test. Read more »

Join us at Foothill College in Los Altos Hills, CA (just 16 miles NW of San Jose, 40 miles south of San Francisco) for the spring conference of the Northern California/Nevada Section of the American Association of Physics Teachers. Starting with a social and physics show, and observatory tour Friday evening, followed by a full day of physics education speakers and workshops on Saturday.
The second draft of the Next Generation Science Standards have come and gone (comment period was in January 2013). The January 2013 draft version has been removed from the official website, but you can still find it here.

All of David’s material related to the Physics of Baseball are available on his website: Phys.csuchico.edu/baseball
David demonstrated the Physics of the Baseball bat including the progression of the baseball bat. He explained how to find the center of percussion of the baseball bat as well as the center of vibration. The “sweet spot” of a bat is where the center of percussion and the center of vibration meet which means that the player will minimize the jarring force of the bat. David showed us many high speed videos from the playoffs that show the compression of a baseball bat being hit and the reaction of the bat after the impact. David demonstrated his rubber bat that has no internal support so that it can create a standing wave. By putting together that information, your students can choose the correction direction that the bat will swing and even guess where the baseball will break if it is outside or inside of the sweet spot.
Pablo shared the physics of the splash hits in the San Francisco Giants Stadium. The ballpark has been designed for maximum home runs and the majority are hit to right field, where the ballpark meets the bay. He discussed the geometry of the park and where a home run is most likely hit.
He has more materials on the change in velocity of a ball hit on different planets, the Physics of a home run, etc. Visit his website for additional materials and videos.
Tom showed us a conducting experiment (picture to come) with two cans and a two copper wires that do not touch and attach to a coup of water. After the cup of water is filled a small neon bulb that that is connected to one of the two copper wires can discharge repeatedly. Tom’s best guess as to why it flashes is that one of the metal cans becomes randomly charged, say negatively, and that negative charge travels up the conducting materials to the water and repels electrons through the other wire to the other side that builds up potential.

Join us at Sierra College in Rocklin, CA (just 20 miles NE of Sacramento) for the fall conference of the Northern California/Nevada Section of the American Association of Physics Teachers. Starting with a social and planetarium and museum tour, followed by a full day of physics education speakers and workshops on Saturday.
Are you interested in presenting at our November 3, 2012 Section conference at Sierra College in Rocklin, CA?
If so, submit your proposal here.
Deadline for submitting is Monday, September 17th.
Members are encouraged to present novel teaching methods, their research studies/results, or other topics you believe would be valuable to other members. For those of you who haven’t presented yet, compared to a National AAPT conference our section conference is a good place to do your first presentation because: Read more »
