A study examines the effectiveness of two major types of instructional technology used in a majority of federally supported bilingual education programs, computer assisted instruction, and video instruction. The videotape technologies examined were bidirectional or interactive television and videotape. The variations of computer technology examined were determined by the configuration of the computing equipment. The study found that technology can have a significant positive effect on limited-English-proficient (LEP) students. In the case of video, the effect was concentrated in two areas: bidirectional television was found to make scarce resources available to geographically dispersed students, and videotape brought the outside world into the classroom while giving the teacher a versatile tool. Computers were found to have the potential for permitting students to learn at their own speed in a highly motivating and non-threatening environment. It is suggested that to maximize the computer's potential, administrators and teachers need training structured for computer application to educational problems. The major impediment to the use of video technology in schools was found to be cost; impediments to the use of computer technology were the lack of instructionally and technologically sound software and lack of training in computer use and planning.
