A Lab Skills Diagnostic Test, John Zwart Jul 2020

A Lab Skills Diagnostic Test, John Zwart

Faculty Work Comprehensive List

The American Association of Physics Teachers recommends that physics majors have proficiency in the following lab skills: constructing knowledge, modeling, designing experiments, analyzing and visualizing data, and communicating physics. I have developed a brief multiple-choice questionnaire to assess incoming students’ lab skill level in these areas. It was administered as both a pre-test and post-test for the first semester of introductory calculus-based physics. Preliminary results indicate that little improvement on the skills tested occurs without explicit instruction.

Systematic Errors In Video Analysis, Tim Martin, Kayt Frisch, John Zwart

Faculty Work Comprehensive List

Video analysis helps students to connect physical, mathematical, and graphical models with the phenomena that the models represent and improves student kinematic graph interpretation skills. The wide-spread availability of easy to use software packages like Logger Pro (Vernier), Capstone (PASCO), and Tracker have led to many introductory physics courses adopting video analysis techniques in the classroom. Such uses include high-speed cameras to study rocket launches and other innovative applications. In this paper, we will look at ways in which some common systematic errors can affect outcomes.
