Abstract
Instructors and the teaching practices they employ play a critical role in improving student learning in college science, technology, engineering, and mathematics (STEM) courses. Consequently, there is increasing interest in collecting information on the range and frequency of teaching practices at department-wide and institution-wide scales. To help facilitate this process, we present a new classroom observation protocol known as the Classroom Observation Protocol for Undergraduate STEM or COPUS. This protocol allows STEM faculty, after a short 1.5-hour training period, to reliably characterize how faculty and students are spending their time in the classroom. We present the protocol, discuss how it differs from existing classroom observation protocols, and describe the process by which it was developed and validated. We also discuss how the observation data can be used to guide individual and institutional change.Entities:

Figure 1.Descriptions of the COPUS student and instructor codes.
Figure 2.A comparison of how two observers coded the student code “Ind.” (A) When the code was described as “Ind: Individual thinking/problem solving in response to assigned task,” observer 2 marked this code more often than observer 1 did. (B) Coding after description of the code was revised.
Information on the courses observed using the final version of the COPUS
| Institution | Number of classes observed | Number of different STEM departments | Percentage of courses at the introductory levela | Percentage of classes with >100 students |
|---|---|---|---|---|
| UBC | 8 | 4b | 100 | 63 |
| UMaine | 23 | 7c | 96 | 35 |
aSTEM courses at the first- and second-year levels.
bBiology, chemistry, math, and physics.
cBiology, molecular biology, engineering, chemistry, math, physics, and geology.

a“SP: Presentation by students” and “TQ: Test/quiz” were not selected in any of the observations at UBC or UMaine. This result likely occurred because when we asked UBC and UMaine faculty members if we could observe their classes, we also asked them if there was anything unusual going on in their classes that day. We avoided classes with student presentations and tests/quizzes, because these situations would limit the diversity of codes that could be selected by the observers.
