“…Introductory psychology is the most popular course in psychology with an estimated annual enrollment in the United States of 1.2–1.6 million students (Steuer & Ham, 2008) and the second most popular college course, second only to English composition (Landrum & Gurung, 2013). Because 98% of teachers use textbooks for the introductory course and the majority of introductory teachers, even at top-ranked liberal arts colleges, do not assign reading beyond the textbook (Miller & Gentile, 1998; Oldenburg, 2005), it would appear that introductory teachers likely “teach the text.” In this context, “teach the text” means that introductory teachers allocate the amount of lecture time for the various textbook chapter topics in about the same proportions as their coverage in introductory textbooks. Therefore, topics receiving more coverage in introductory textbooks receive more coverage in lecture.…”
