We converted the Teacher Behaviors Checklist (TBC; Buskist, Sikorski, Buckley, & Saville, 2002) to an evaluative instrument to assess teaching by adding specific instructions and a Likert-type scale. Factor analysis of the modified TBC produced 2 subscales: caring and supportive and professional competency and communication skills. Further psychometric analysis suggested the instrument possessed excellent construct validity and reliability, underscoring its potential as a tool for assessing teaching. This instrument clearly identifies specific target teaching behaviors that instructors can alter to attempt to improve their teaching effectiveness.
