Classroom observation data using tools such as the Classroom Observation Protocol for Undergraduate STEM (COPUS) are frequently collected in instructional settings for large-scale research studies and program assessment. While COPUS data may be provided to instructors, it is often provided with little or no guidance on how the data can be used to inform teaching practice. This communication is designed to serve as a guide for chemistry instructors to understand the COPUS data from their course, facilitate engagement with the results, and provide strategies for making meaningful changes in response to the data.
