The introductory class in higher education: Some old problems and new considerations.

The traditional text and lecture format has remained the norm in introductory college courses despite evidence, such as the personalized system of instruction, that other practices could improve what is learned and retained. The growth of distance learning provides new opportunities to implement effective teaching practices. Unfortunately, an adequate comparison of various teaching practices is not possible (even with regard to the teaching of behavior analysis). Few practices have been assessed with respect to course-end effects (final exam performance), and longer term effects remain almost wholly unexplored. Studies of the retention of academic materials, the practice required for mastery or fluency, and the relation between verbal repertoires and correspondent everyday behaviors suggest course outcomes more modest than those hoped for earlier. Suggestions for changing current practices have little credibility until the size of the gap between present and possible learning outcomes is much better known, and the personal, social, and economic consequences of bridging that gap (or not) are assessed.
