Faculty members (N = 39) from two universities had their lectures recorded. From these videos, we selected 5-min vignettes centered on eight dimensions of the Teacher Behavior Checklist. Undergraduate students from two universities (N = 753) viewed three 5-min video clips of college teachers across various disciplines. Ratings on the eight dimensions (knowledgeable, respectful, approachable, realistic, enthusiastic, encouraging, flexible, and creative) were moderately to strongly intercorrelated, and students had high agreement among themselves in rating each instructor’s teaching behaviors. The methodology to establish reliability of student ratings of video clips may be useful in future validity studies to assist in providing evidence-based examples of effective teaching.
