This paper is based upon the presentation by the author on the above title at the poster session of 18th Annual International Conference on November 22,1992 at Tokyo International University, Kawagoe, Japan. The display consists of 38 exquisitely illustrated, handmade learning materials generated by college students. Themes reflect a wide range of students' interests, including daily life, nature, body language, proverbs, sports, the information of the world (oceans, stars, countries, states, cities, populations, national currencies, flags, products, etc.) and Japanese culture and geography. They were made to contribute to learners of English and also to non-native speakers of Japanese in Japan. They are suitable for learning and practicing vocabulary, grammar, and communicative usage. They were made to help acquire both English language competence and general knowledge on the world and on your daily life. In this paper I would like to discuss why and how I stimulated students to generate learning materials and what materials they generated and what they have learned in the process.
