본 연구의 목적은 고등학교 지구과학 I의 단열변화 주제에 관한 교과서별 내용을 분석하여 향후 교과서 집필 방향에 시사점을 제공하기 위한 것이다. 연구를 위하여 8종의 고등학교 검인정 과학 교과서 중, 일선 학교에서 많이 사용하고 있는 6종의 교과서를 분석 대상으로 선정하였다. 교과서 분석에는 전주시 소재의 교원 양성 대학교에 재학 중인 예비교사 35명이 참여하였다. 먼저 연구자가 사전에 6종의 분석대상 교과서를 살핀 후, 분석관점을 단열변화에 대한 개념 정의, 단열변화에 대한 삽화, 단열변화에 대한 실험의 세 부분으로 범주화하였다. 이를 바탕으로 6종의 교과서를 분석한 후 각 범주별로 가장 우수한 교과서를 선정하였다. 연구 결과 단열변화에 대한 개념정의는 교과서 A, 단열변화에 대한 삽화는 교과서 C, 단열변화에 대한 실험은 교과서 B가 우수한 것으로 선정되었으며, 6종의 교과서 모두 불완전한 부분이 있음이 확인되었다. 이러한 교과서의 부정확성, 부적절성은 학생들이 단열변화를 이해하는 데 어려움을 초래할 수 있으며, 더 나아가 오개념을 형성하도록 하는 문제점을 가져올 수 있다. 따라서 단열변화에 대한 보다 체계적이고 정확하며, 완전한 내용이 담겨지도록 교과서의 내용을 재구성할 필요성이 있다.

We investigate the forms, the inquiry levels and the objective types in the inquiry activities of the Earth Science text book (Science I HA) that was reorganized at March, 1988 from the eight publishers, according to the reference of Schwab's(1966) inquiry level of experiment and the Klopfer's (1971) classification of objectives of science education. Ninty seven percents of the experiments belong to the 1st level of the Schwab' s(1966) inquiry level and there are no activities of the 3rd level. On the basis of Klopfer's classification, ninty eight percents of the inquiry objectives are included in the only four kinds (A.O, B.O, D.O, G.O) of the nine objectives, and the rest (C.O, E.O, F.O, H.O, I. O) of the important objectives that are indispensable to the inquiry process seems to be exclusive. Conclusively speaking, the inquiry ability of the students may not be cultivated by the experiments in present text-book.

The aim of this study on analysis of curriculum of high school Earth Science is; 1) To investigate whether experiment and observation unit are properly organized. 2) To provide useful materials for reorganization of Earth Science curriculum in future. 3) To suggest that the curriculum be operated properly in the era of 2000s. This study reaches the conclusions which are as follows; 1) After classifying the course of experiment and observation, we have found it difficult to help the students inquiry learning for they are organized only to be explained by teacher on the purpose of passing entrance exam. 2) It is difficult to help students make an experiment because of laboratory's lack. So it is necessary for the education authority to require the situation and to support its system actively. 3) Lack of experimental equipments and classroom schedule for experiment make it difficult to make an experiment in most schools(For example 89.1 % of the whole school lack implement, 52.7% lack prepared hours, 73.6% perform less than 5 hours a week). 4) It is not proper to divide the curriculum into Earth Science(I) and Earth Science(II). Most of teachers tell that the teaching material is somewhat difficult for the students to understand and the quantity of those is too much(80.9%). 5) Those who study liberal course are inclined to choose Biology(82.7%) and those who study natural science, Chemistry(76.4%) or Biology(79.1). In most high school they are forced to run curriculum unfairly on account of this present condition.

This study aims to present an effective basic material and data . for the future earth science education by examining the present condition of scientific laboratory and observation unit of earth science test books. The method used in this study is based on the questionnaire obtained from the earth science teachers throughout the nation and an analysis of reference material related. The main subject of this study is the basic qualification of earth science teacher, the present condition of laboratory equipment, the status of scientific experiment and the problems of earth science experiment kits. Based on the above investigations, suggestions are presented for future earth science education: (1) The laboratory and observation education should be more emphasised than lecture. (2) A team should consists of 10 students at laboratory. (3) It is in urgent need to publish a laboratory manual for the student. (4) Well designed laboratory equipments and good quality kits of reasonable price should be supplied.
