We have developed two media mix designs marked with hypermedia. One is teacher-support model, and the other is learner-reflection model. Teacher-support model has three stages, each stage involving a set of information processes; gathering, modifying and delivering information. These stages form a spiraled structure, and multi-dimensional thinking with hypermedia is located in the third stage. Learner-reflection model consists of four sessions; two information-gathering sessions, information-producing session and information-organizing session. Children use hypermedia to reflect their experiences in the second of information-gathering sessions. We have organized media systems based on these models, and applied them to the learning units "Man and Forest." Subjects of the study are 28 5th-grade children and 13 6th-grade children in Kanazawa, Ishikawa Pref. Pre-, in- and post-unit researches were implemented as instructional evaluations. Tools used for the evaluation were image map tests and interviews. Results of the evaluation are as follows; our subjects have attained the procedure of a multi-dimensional thinking about the man and forest. Moreover, some of them have improved their media-literacy.
