The main purpose of this paper was to identify the problems of existing classroom process and to search for instructional improvement To accomplish this purpose, studies on various instructional aspects including teacher's instructional planning, classroom control and instructional management, teaching methods and strategies, interaction between teacher and students, and instructional evaluation were performed in terms of ethnographic methods(narrative observation, participant observation, in-depth interview). According to classroom observations and interviews with teachers, much variables in instructional process are assumed to interact in various modes. In partiqular, teacher variables, student variables, and context variables(or environment variables) are effected on teaching-learning activities in a dynamic interactive process on another. And thus, in order to do the proper study on classroom process, there is a need to analyze the instructional events with consideration those variables simultaneously. For our opinions, it is judged that the present instructional practices in elementary school are not only inappropriate for desired learning experiences of learners, but also ineffective in view of good teacher's teaching behaviors. Most of existing instructional activities in the classroom are proceed in a mechanistic and injective teaching style and in a passive and static learning style. It can be said that the fundamental reasons for these problems are teacher's non-professional teaching competencies as well as learners' non-subjective learning activities. In view of the results of this study, it is very important that instructional process in classroom is ougth to proceed with consideration the followings as a whole context; 1. preparing the instructional planning & readiness(analyze of objectives and learning tasks, diagnosis of learner's characteristics) 2. operationg the classroom control & instructional management(praisng and punishing mechanism, structured cues and advanced organizers, instructional atmosphere) 3. teaching methods & strategies(instructional model, media, and techniques) 4. implementing the interaction between teacher and learners(pattern & level of questions/answers, teaching -learning styles) 5. evaluating instructional activities(summative evaluation, formative evaluation, diagnosis evaluation, and self evaluation).
