The Institute for the Study of Adult Literacy developed and field-tested a curriculum and instructional materials for teaching occupationally specific vocabulary in the health care field. The materials, which are in the form of a narrative about a woman who learns medical terminology from a friend, were designed to serve as a vehicle for training students to use structural analysis to understand vocabulary relevant to the responsibilities of beginning licensed practical nurses (LPN). Project staff reviewed existing medical vocabulary texts and assembled a list of medical vocabulary word parts that were then each reviewed by three working registered nurses to determine their relevance to a beginning LPN. A pretest/posttest format was used to field-test 11 adult learners at two sites in Pennsylvania. The mean pretest score was 6.91 out of 45 (range, 3 to 15), and the mean posttest score was 39.27 (range, 33 to 44). Both the instructors and adult learners who used the new curriculum and materials reacted positively to them when interviewed. (MN)
