Measuring Teacher-Centered and Student -Centered Teaching Introduction of a Classroom Teaching Observation Sheet

There is a lack of instruments for measuring teaching behavior in academic learning. This article introduces an observation sheet (BEO-LV) that allows for a descriptive measurement of teacher-centered and student-centered teaching. To facilitate teachers' acceptance of data collection, observations may also be used to support professional development activities. Here we present two studies examining the psychometric properties of the BEO-LV: (1) The interrater agreement and interrater reliability in an observation-based study were found to be satisfactory. (2) The interrater agreement and internal validity in a video study were found to be satisfactory for observers with advanced didactic knowledge. The results indicate that the BEO-LV is suitable for measuring teaching behavior. To achieve good psychometric results, the observer must have detailed insight into the operationalized definitions of the items.
