I was at the NSTA National Conference in Chicago today. My students did something different while I was gone. My colleagues and I have been working on a series of measurement and analysis assessments. We plan to administer these to the AP Physics 1/2/C classes and track how students do throughout the year and from year to year. We defined the following standards:
- Retrieve quantitative data from an experimental source and organize it in a data table denoting; units, dependent/independent variable.
- Properly plot data and determine type of fit, fitness of fit, establish mathematical model with proper units.
- Properly analyze and make sense of the slope and intercept of the derived mathematical model.
- Apply the model to a different situation.
For the first assessment we used the Direct Measurement video of the Ping Pong Cannon.
