This report describes research on the use of interactive video in elementary schools which was carried out in the comprehensive school at the Institute for Education Research and the Department of Teacher Education in the University of Jyvaskyla, Finland. The research is based on students' attitude ratings of different working modes in the comprehensive school and observations videorecorded in learning situations where students worked with interactive video. The students rated interactive video as a very popular working mode in science and art education. The observations of the videorecorded learning situations indicated a very high activity level and few cases of disturbing behavior among students. This research showed that interactive video will change the role of teachers and teaching materials. The student will actively search for and modify information with the new medium, thereby taking a measure of control over learning. It was found that levels of student participation in and motivation for learning increased through the use of interactive video. Nine of the 26 references listed are in Finnish, most of them with English summaries. A student response sheet is appended. (Author/DB)
