Final report : investigating, developing, adapting, and testing interactive videodisc science instruction for LDC"s

A low-cost, integrated videodisc/computer system was developed by the Nebraska Videodisc Design/Production Group for use in the classroom. The videodisc was designed to be the primary source of information for two lessons which are part of the standard freshman science curricula, one in chemistry and one in physics. The computer system allowed each student to control the pace of the lesson and to answer questions posed in the instruction. The computer also judged the correctness of the answer and either required that the student re-evaluate his/her response if it was incorrect or allowed the student to proceed if the answer was correct. Of the 90 students involved in the field test at the Institut Teknologi Bandung in Indonesia, nearly all responded positively to videodisc instruction. Both the students and teaching assistants strongly agreed that science laboratory instruction via videodisc held students" interest, and the majority of students felt they learned as well or better via the videodisc instruction than they did with regular laboratory instruction. As a result, they encouraged the use of more videodisc science instruction. The equipment was reliable and did not interfere in any significant way with instruction. Based on these results, it is recommended that additional research be conducted in developing low-cost, computer-controlled videodisc science instruction for LDC"s.
