A general model of instructional communication is advanced and the linkages of four components in the model are tested. Data were drawn from college teachers and college students through a split‐class design which permitted collection of unique data from teachers and two sets of their students. Using by‐class analyses of data it was determined that teacher self‐reported temperament is significantly correlated with students' perceptions of the teachers' communication behaviors and the students' evaluation of teachers' source credibility and task attractiveness. All of these measures were also found to predict learning outcomes and teacher evaluations of another group of students. The results support the general model and provide a foundation for future research in instructional communication.
