This quasi-experiment examined how incorporating an instructor narrative into teaching augmented students' recall, affect, and sustained attention. One hundred and ninety-four undergraduate students were assigned to one of two teaching conditions in a college classroom: a lecture that included an instructor narrative summarizing the lesson's key…

Guided by self-determination theory, we conducted a live lecture experiment in two 50-min college courses to manipulate autonomy-supportive instruction (i.e., the amount of choices and rationales offered to students). Participants were 201 undergraduate students who either attended a lecture where the instructor gave students choices over the…

This study tested the notion that the effect of instructor clarity on learning is conditioned upon students' motivation. We randomly assigned 128 participants to a video of a clear or an unclear lecture and asked them to report their motivation to deeply process lecture material. Results indicated that even with clear instruction, test scores were…

Guided by assumptions from the cognitive-affective theory of learning with media, we conducted a teaching experiment to corroborate past correlational research that suggested instructor misbehaviors, in the form of antagonism toward students, impede students' cognitive learning. Participants were 472 undergraduate students who were randomly…

Three studies (N = 1119) were conducted to replicate and expand upon Kearney, Plax, Hays, and Ivey's seminal research on instructor misbehaviors. In study 1 (n = 233), a replication of Kearney et al.'s study revealed 43 categories of perceived instructor misbehaviors; 27 of the misbehaviors were originally identified by Kearney et al. and 16 new…
