Some effects of training on teaching effectiveness of untrained university teaching assistants

This paper presents an assessment of the effects which a brief training program had on teaching effectiveness of graduate teaching assistants (TAs). Twenty-two inexperienced and previously untrained university TAs from economics, geography, and business administration were assigned to a training or control group by a stratified random method with stratification based on TA departmental affiliation. Teaching experts rated two videotapes of each Ta's university class, one tape made before training and one following training. Ratings were obtained on two factors: (1) planning instruction to meet clear goals and organizing meaningful content in a logical fashion, and (2) involving students in instruction. Results from analyses of covariance indicate that the training group received significantly higher final ratings than the control group on the total score and on each of the two factors when final scores were adjusted for group differences in initial ratings. Teaching experience alone did not result in significantly higher ratings for control group TAs. Participants in training evaluated most topics and the overall program favorably both immediately after training and one semester later.
