Little is known of the role of classroom instructors in televised college courses. Student achievement may be affected by classroom instructors' behaviors during the presentation of the televised lecture and during face-to-face discussion afterward. It was hypothesized that student achievement would be greater when classroom instructors were present during the lecture but did not conduct discussion than when classroom instructors were absent during the lecture but conducted discussion. The hypothesis was supported ( p < .01). Possible distortion of previous instructional television research findings due to novelty, Hawthorne, and time effects was discussed.
