The Texas Learning Technology Group (TLTG) is a non-profit organization formed in 1985 by the Texas Association of School Boards, the National Science Center Foundation, and 12 Texas school districts. Believing that science education had become characterized by a shortage of qualified physical science teachers, a high failure rate, a lack of student motivation, and a decreasing number of students enrolling in advanced science courses, the organization established a three-fold mission: (1) to develop high-quality curriculum programs that integrate educational technologies into instructional delivery systems; (2) to evaluate the educational effectiveness of technology-based curricula; and (3) to educate teachers in the use of new technologies and provide support to schools implementing these new curricula. The core of the resulting 15-unit TLTG science program is its interactive video-based instruction. Robbins Secondary School was selected as a site for the TLTG physical science program to determine if interactive video instruction could also enhance the learning of at-risk students. An evaluation of the program found that most students evinced a positive attitude toward the technology provided, felt comfortable using the computer assisted instructional system, enjoyed learning science that way, and felt they were learning the material better using this technology. Survey results also indicated that, despite positive student attitudes, they did not express an interest in continuing science classes. Finally, students' grade equivalent scores on the TAP Science Test were lower than typical for their grade and lower than those of other students at Robbins. A copy of the attitude survey instrument is appended. (3 references) (DB)
