Urinalysis by modular learning.

A self-instructional approach to the entry-level presentation of urinalysis in a written modular format was used by a class of medical laboratory technician students. The course consisted of 13 modules based upon behavioral objectives. The modules used no audio or visual media but required "hands-on" performance of laboratory procedures. The achievements of a test sample of 12 students were compared with those of a previous class in which the same material was presented in lectures. Evaluation by written tests given to both classes showed no statistical difference. The self-instructed students performed adequately in their practical laboratory work, but the overall learning time was increased by 50 percent when self-pacing was used. A measurement questionnaire revealed that the students preferred instructor-led courses to self-instructional units for a variety of reasons which lead to some further considerations.
