"Saturday Subway Ride," a program designed to teach pupils creative thinking techniques and positive attitudes toward creative ideas, is a 92-page workbook in a story-exercise format. Secondary objectives for the product include improving verbal fluency and creative writing. Three classrooms 61 sixth graders and 34 fifth graders at two Wisconsin schools, used the program for two months. The purpose of this paper is to report the results of this initial field study. The major findings included information on the usability of the product and student attainment of product objectives. Teacher annotations, on-site visitations and rated pupil workbooks indicated that considerable reworking of the exercises was needed, although the teachers gave satisfactory ratings to the program overall. Ratings of the exercises showed that only some pupils learned adequately the five techniques of creative thinking: Part-Changing, Checkerboard, Checklist, Find-Something-Similar, and Brainstorming Methods. Changes from pre-test to post-test on the 22-item attitude survey and the verbal fluency tests were both significant and positive. Finally, ratings of short writing samples showed improvement for girls but not for boys from pre-test to post-test. (Author)
