Abstract
The purpose of this study was to obtain the basic information about instructional activities for development of knowledge and information sharing system. At the first stage, we collected and classified descriptions of instructional activities for class teaching from five books of Japanese Language Teaching Methods. Major findings were as follows: 1) 294 instructional activities were classified into eight categories (level, area, skills, purpose, method, type, environment, resource) But some categories were not applicable to every instructional event. 2) Descriptions of instructional activities were classified into three types: steps of instructional procedures, concrete examples, and learners' problems. Half of instructional activities were described by means of concrete examples. 3) In the description of instructional activities, concrete examples were mainly used at basic level, but both instructional procedure and concrete examples were used at intermediate and advanced level.
