Use of class time Measured via COPUS profiles

?

•  What variety of teaching practices are currently used in our program?

•  What are the relationships between specific classroom practices and student learning?

Characterizing Classrooms using COPUS1,2:

During a classroom visit, student and instructor activity codes are checked off in 2-min intervals. Each classroom can then be characterized:

•  Student Performance here is defined as the Percent Normalized Change on the diagnostic test: (postscore-prescore) / (1-prescore) if post > pre.

•  As expected4, classes with higher levels student-centered peer instruction result in higher performance •  There may be a ‘sweet spot’ for the amount of lecturing – need to analyze the rest of the data to see.

Goal: identify these
