Abstract
The Educational Technology Center of Florida State University developed a new model for the Selection of Media for Instruction, based on the R. M. Gagne's Theory of Instruction (Reiser & Gagne, 1983). This model is an integration of the research findigs that the Center conducted for several years. The purposes of this article are: (1) to introduce the new model by Reiser & Gagne, which has been developed in order to select instructional events that can be occured only by using media; (2) to discuss how various factors related to the selection of media for instruction are explained; (3) to clarify that the results of both the theory of development of systematic design and the one of instruction are very important for instruction in classes, as well as practical factors, such as cost or media characteristics. Among many research activities on educational technology, few research results are practical and are useful for teachers or those who have developed instructional curricula. The new model by Reiser & Gagne has an important meaning in the sense that in reformed the Gagne's proceeding theory into the one which can be realised.
