Abstract
Many reports exist of educational practices that introduce experiments and manufacturing into lessons for the purpose of promoting students' motivation for learning, supporting their independent learning, and training their problem solving ability. Various teaching materials are developed to support these teaching and learning activities. We have developed a multimedia learning support system of ultra micro-wind turbines. This system consists of teaching material concerning fundamental knowledge and theory of wind turbines, the database and the software program for predicting wind turbines' performance. Ultra micro-wind turbines of 220-mm diameter are produced from paper; the database is produced based on experimental values of their performance. The software program for predicting wind turbines' performance is developed based on this database. Students learn fundamental knowledge and theory of wind turbines and refer both to results predicted by the software program and to actual data of the database; then they produce wind turbines using paper. Effectiveness of these three kinds of teaching materials is software program was verified through these students' activities.
