Introductory Lab Course (In-Person)

PER Fiber Optics

We transformed our introductory physics lab course to better prepare students for future courses and careers. We began by soliciting input from a variety of university stakeholders including faculty and staff from both physics and the College of Engineering and Applied Science. The consensus learning goals are listed below.

(1) Students鈥 epistemology of experimental physics should align with the expert view.

(1a) Alternative Definition: Student鈥檚 beliefs about the nature of experimental physics should align with expert physicists. This includes understanding that physics is an experimental science, what makes for a valid measurement, and how knowledge is gained through experiments.

(2) Students should have a positive attitude about the course.

(3) Students should have a positive attitude about experimental physics.

(4) Students should be able to make a presentation quality graph showing a model and data.

(5) Students should demonstrate a set-like reasoning when evaluating measurements.

(5a) Alternative Definition: Students should understand that a measurement has an associated uncertainty and is not the 鈥渢rue鈥 value. They should understand that repeated measurements form a distribution with a mean and a standard deviation.

The course is designed around four three-week modules: Experimental Skills, Mechanics, E&M and Optics. Students work on guided inquiry labs in pairs. They record their predictions, data, analysis, and outcomes using an electronic lab notebook (OneNote) on a tablet provided for them in the lab.
