The American Association of Physics Teachers (AAPT) was formed in 1930, and today it has over 10,000 members in 30 countries. Their educational outreach work is significant, and along with the usual conferences and professional development meetings, it includes this website. Here visitors will find several video guides, including one that documents the well known collapse of the Takoma Narrow Bridge in 1940, which is a commonly used case study in physics and engineering courses. Also, the site includes a seven part instructional series designed to be used with a DVD series. Visitors do not need to have the program to appreciate or use the guides, and they cover over a dozen topics, including kinematics, conversation laws, and electricity. The materials here are rounded out by a PowerPoint presentation on teaching about energy.
