A practicum was developed to create a high school television production that would develop and improve the broadcast journalism students' critical thinking skills. A 5-minute daily newscast (written, produced, and telecast by the students) was initiated during a 10-week period. Students had the opportunity to become involved in a variety of the following roles: news director, producers, timers, floor director, floor manager, studio production crew, remote production crew, news reporters/anchors, video engineer, and lighting engineer. Additionally, pre- and postcritical thinking skills tests were administered to the 150 participating students, asking the subjects to identify inferences and to evaluate the meaning in an ambiguous news story. Results of the program implementation and testing revealed improved skills in organizing information; analyzing the content of materials gathered for a news story; synthesizing and ordering facts in an understandable presentation for a high school audience; and evaluating content and visually presenting ideas for a fair, accurate and balanced news report. (Twenty appendixes containing testing data, production criteria, broadcast format, instructional objectives, lesson plans, and class assignments are attached.) (KEH)
