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, directions for the experiment and questions; and a teacher's guide with answers to the questions in the manual, a list of learning objectives and a quiz. Student attitudes and study procedures were determined by means of questionnaires and personal interviews. Student learning outcomes were assessed from quizzes, interviews, and student reports. The data showed that most students achieved the important learning objectives. Significant differences were found between quiz scores of students using the units and an equivalent control group.
