A program is described in which hospital patients receive videotaped medication instruction that is reinforced by printed information. In a 940-bed hospital, the pharmacy department developed a series of videotapes for closed-circuit television. Each tape covers a medication or drug class and includes use of the drug, precautions, administration instructions, and adverse effects. Pharmacists developed the basic test, and the patient education department revised the language to meet the needs of patients. Pharmacists presented the information on the tapes, which were produced by the hospital's video production department. File cards that paraphrased the script were designed to give patients written information to take home. Each tape is shown once daily. The tape includes the pharmacy phone number and encourages patients to call the pharmacy to obtain a card. A pharmacist delivers the cards and reviews the information. In this program, information can be presented to a large number of patients with minimal use of pharmacists' time.
The purpose of this study was to determine whether computer-assisted instruction (CAI) is as effective as the lecture method of instruction (LMI) for teaching sanitation to hospital foodservice employees. Two dependent variables--gain in sanitation knowledge and amount of time required to complete the training experience--and three independent variables--treatment, age, and level of education--were examined for each treatment group. Attitude toward sanitation training and CAI was appraised for the groups prior to training and for the CAI group after training. A sanitation knowledge instrument was administered as a pre- and post-test, and a Likert-type attitude assessment questionnaire was utilized to provide an indication of participants' attitude toward sanitation training and CAI. Findings indicated that significantly more training time (97 vs. 32 minutes) was required by the CAI group than by the LMI group. Participants younger than 25 attained significantly higher gain scores (X = 11 vs. X = 10) with CAI than with LMI. Gain scores for other age categories tended to be higher for individuals taught by CAI; however, they were not significantly different from the scores of those taught by LMI. CAI group members demonstrated an improved attitude toward CAI and sanitation training. It was concluded that the CAI and LMI methods were equally effective for teaching sanitation for most of the employees who participated in the study.
This study was undertaken to evaluate two methods of instruction, the traditional lecture and the slide-tape method, both used with learning material developed for a course in endodontic diagnosis and treatment planning. Student performance, the amount of time required to complete the work, and the attitude of the students toward the differing methods of instruction were studied. The student sample, consisting of 108 members of the freshman class at the University of Southern California, was divided into two groups; the lecture group received a traditional two-hour lecture, and the slide-tape group had access to two slide-tapes on the same material. Both groups received a pretest and a posttest, and the students evaluated the teaching material. Statistical analysis showed no significant differences in quality of performance, but the lecture group spent more time learning the material, and students in the slide-tape group of instruction had a more favorable opinion of both the instructor (the voice) and the course material.
