In cooperation with the United States Navy, this project was undertaken to examine the feasibility of computer assisted instruction in clinical malaria recognition, to train a small group of Naval personnel in techniques of creating and presenting such material, and to evaluate the course by giving it to a representative sample of Naval medical officers and laboratory corpsmen. Students were to learn to prepare blood smears, to recognize malarial parasites and artifacts in 2 X 2 micrographs, and to use the microscope on prepared 35mm slides. The course was constructed in five short segments. Positive feedback from live demonstrations held in Philadelphia, Washington, D.C., and Cambridge encouraged the development of course segments as initially conceived. The diagnostic test, the instructional segment, and a portion of the drill segment have been completed and tested by Naval medical personnel at Bethesda. Revisions to portions of the instructional segment are now being made on the basis of student performance records. The course will be translated from the language of the IBM 1410 to Coursewriter II.
