Visual cues, student sex, material taught, and the magnitude of teacher expectancy effects

Abstract
An experiment on teacher expectancy effects was conducted to investigate the simultaneous effects of student sex, communication channel, and type of material taught (vocabulary or reasoning). Magnitude of teacher expectation effects was greater when students had access to visual cues, expecially when the students were females. This channel by sex interaction was greater when vocabulary rather than reasoning material was being taught. Teachers with higher expectations for student performance taught more material, especially vocabulary, to those students.
