Teaching Science Using Interactive Videodisc: Results of the Pilot Year Evaluation of the Texas Learning Technology Group Project
A computer-based interactive video was developed in 1985 for the Texas Learning Technology Group (TLTG) Project, a partnership formed by the Texas Association of School Boards, the National Science Center Foundation, and 12 Texas school districts in response to the national and state crisis in science, math, and technology education. A pilot test of a semester-long high school chemistry curriculum delivered by TLTG was conducted during the 1987-1988 school year, in part to investigate teacher attitudes and teacher implementation behavior. Twenty-six teachers participated in the interactive videodisc (IVD) study, which also made use of records of 2,297 students and achievement data collected from a sample of the students (N = 338). The major findings revealed that IVD students generally achieved higher scores than non-IVD students; IVD students indicated a greater degree of intention to enroll in an elective science course than control students; most teachers liked using the curriculum and found it easier to teach than the traditional curricula; all teachers used supplemental materials in conjunction with the curriculum; and all teachers felt that their students had learned more using the TLTG curriculum than they had learned in previous years. Both videotaped classroom observations of the TLTG curriculum and staff visits to all of the school districts using the curriculum were made during the pilot year. A new evaluation plan has been formulated for the field test year of the TLTG evaluation (1988-1989), and data are being collected on the actual on-site implementation of the TLTG field test curriculum.
