Reported are some findings from a study designed to discover the opinions of science educators about the procedures they used in the development of audio-tutorial (AT) lessons and/or minicourses. (PEB)

This study was designed and conducted to determine the effectiveness of audio-tutorial minicourses in increasing achievement in the biological sciences at the college freshman level. In 1971, 75 randomly selected students in the experimental group attended regular lecture and laboratory periods in addition to completing 10 minicourses. The 79…

Compares a self-paced laboratory to a conventional laboratory; the students in the self-paced group achieved significantly higher grades and were enthusiastic about the format. (MLH)

Determined was the effect of autotutorial instruction in the laboratory portion of a general biology course designed for nonbiology majors. Results indicate positive effects in enrollment, increased retention, and improved student achievement. (CS)

This is a report of the development of four self-study units in physics for college nonscience majors. The topics of the units are Waves and Sound, The Radiant Energy of Sunlight, Infrared Radiation, and Acceleration. Each unit includes an inexpensive, portable kit; a student manual containing all requisite background information, self-test,…
