This comprehensive field test report describes a 1978 impact evaluation of the 3-program "Collecting Information" cluster of ThinkAbout, a series of 60 15-minute instructional television programs for fifth and sixth graders designed to strengthen reasoning skills and review and reinforce language arts, mathematics, and study skills. The ThinkAbout Project and the specific Collecting Information cluster (one of 13 in the series) are explained, as well as the design and implementation of the field test, which assessed the classroom process, student outcomes, and teacher reactions. On the basis of data gathered through observations, questionnaires, story problems, and interviews, it was concluded that classroom use of the cluster met the project expectations. Appendices contain the teachers' guide materials and data collection instruments used in the field test, cognitive structure and multidimensional scaling techniques, agenda for observer training sessions, analysis of variance tables for student questionnaires, and teachers' comments on the cluster.
