지난 십여년 동안 학생들의 자연 현상에 대한 직관적 견해가 활발하게 연구되어 왔다. 그러나 지구과학 분야에서는 소수의 개념만이 연구되었다. 학생들의 직관적 견해 연구 대상으로 지구과학의 가능성이 이론적 및 실증적 견지에서 고찰되었다. 그 결과 지구과학의 연구 대상인 여러 자연 현상에 대하여 학생들이 많은 직관적 견해를 보유하고 있을 가능성이 매우 큰 것으로 밝혀졌다. 이미 발표된 지구과학 분야의 직관적인 견해에 대한 연구들이 현재 이 분야의 연구 진척 상황의 이해 및 지구과학 교수 학습에 활용을 위해 소개 되었다. 직관적 견해의 과학 학습에의 중요성과 지구과학의 전국민의 과학적 소양 함양 및 초·중등과학 교과 과정에서의 중요성, 지구과학 분야에 대한 학생들의 직관적 견해 보유 가능성, 그리고 대부분의 지구과학 분야에 대한 직관적 견해 연구의 부족함 등을 감안하면 앞으로 지구과학 분야에 대한 학생들의 직관적인 견해는 계속적인 연구가 요청된다.

1. The aim of this study is to find the theoretical foundation of science education and to offer a basic materials and efficient suggestions for the 2000s Earth Science by analyzing and comparing the new curriculum amended in 1988 and the old one amended in 1981. 2. The main contents of this study is to find the problems in curriculum and to suggest the way to improve the curriculum by analyzing and comparing the new and old curriculum. 3. The problems that may appear in the new curriculum are as follows. (1) It's hard to expect the normal Earth Science Education in high school because Earth Science is designated as an optional subject in natural course. (2) It is contradictory to relation in learning to unify the Earth Science I and Biology I into Science I in new curriculum. (3) If the new curriculum goes in effect it is natural that Earth Science teachers quality should be lowered because able students will avoid entering the Department of Earth Science Education in university. 4. The suggestions to help improve the Earth Science curriculum in 2000s are as follows. (1) For the normal Earth Science Education, Earth Science should be designated as a required subject in civic science course as well as in natural course in high school. (2) The aim of Earth Science Education should be amended not to be dicipline centered curriculum but to satisfy the future society or individual's desire (3) The intergrated science should be researched profoundly and it is necessary to name Earth Science Geophysics, which is unified with physics. (4) Natural science curriculum should be amended by the committee constituted with the specialist in science education, scientists, and science teachers ; it is not proper that science curriculum be reached and discussed by an reorganization in which a few specialists in science education join.

The aim of this study is to provide useful advices and basic data for the future Earth Science Education by analyzing the High School Earth Science textbooks. The analysis included 1) whether the contents of the textbook are properly selected suiting with Piaget's Intellectual development stage 2) whether the basic concept and successive concept are properly selected and organized. This study arrived at the following conclusions. 1) The greater part of highschool students are not able to think the formal operation when they are in need of thinking power in formal operation in the study of 48.696 of curriculum. 2) The contents of Earth Science textbook should be developed naturally from the concrete operation stage to the formal operation stage, but the methods of approaching curriculum are scattered through out the textbook. 3) There are many lessons that can't be practiced in laboratory. The textbook should be developed naturally from the simple structures to the complicated ones. Also it is necessary for teachers to conceive those problems and to be able to help the students approach the curriculum easily.

The plate tectonics is the theory which can systematically interpret various kinds of changes of crusts on the earth surfaces. If the concepts of this theory is taken a triangular position and systematically played up at the curricula of the earth science in the high school, this theory may be able to become the most adequate subject for students to interest in the earth science. The aim of this study is the making out the expanded model of the unit of plate tectonics for the purpose of the more effective teaching-learning of the plate tectonics and the improvement of curricula on the plate tectonics in the high school.

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.

The general aspects of the selection of science subjects for the enterance examination of college and the factors affecting on tendency of the selection were investigated by using the data of registration records from a preparatory school for examinees. Major findings of this study are as follows. Firstly, most of the students choose biology and the rest of them chemistry, earth science and physics in order. Secondly, the difference of the tendency of selection of subjects for male and female students are not found. Thirdly, the correlation between the score of the national preliminary enterance examination for college and that of the trial examination in preparatory school is neglibibly small.

Four observational astronomical item, have been pilottested with a 150mm refracting telescope in order to layout the detailed procedures for the suggested (inquiry) activities listed in the high school earth science curriculum and to contrive some adequate instructions for students stressed on how to make proper treatments with the collected materials. The tested items were of sunspots' motion, the size of lunar craters, the Galilian satellites' revolution, and the galactic distribution of stars. Following series of activities are suggested with respect to the way of collecting observational data and of giving proper instruction to students in class: 1) Photography and other material, he made by teacher and/or extracurricular group of students; 2) Replicas (xeroxed, photographs, Or slides) he made from the collected materials, '0 that they are available to all the students in class; 3) Quantative analyses, be taken as student' activity.

This study aims at giving effective suggestions for future Earth Science Education by making a theoretical teaching-learning model for inquiry science. The main subject of this study is to establish the learning system, educational goal and guide theory of Earth Science Education. Through above mentioned, following suggestions are presented: (1) The experiments and observations should be more emphasized than lectures in Earth Science Education. (2) It is necessary to retrain Earth Science teachers in order to improve their ability to guide the student's experiments. (3) Well designed laboratory equipments and kids of good quality and resonable price should be supplied. (4) Every teacher should work on positive line, extending the range of information through participating in the Korean Earth Science Education society, Earth Science meetings and various science education seminars.

The papers of earth science examinations given during the first semester of 1981 academic year were collected from the seventy five high schools randomly chosen all over the country. The examination questions were analyzed and evaluated in order to grasp the current state and issues of earth science education. Some critical remarks and suggestions are made for improvement of the earth science education at the secondary school level.

The purpose of this study is to classify and to analize the instructional objectives in teacher's guides of high school earth science course. The Romey's definition of instructional objectives was based for classification. The results of the study show that approximately 77 percent of total action verbs appeared in all teacher's guides are classified as level NO and level O. The dominant usage of such non-inquiring words may prevent the students from doing investigative activities. The level NO verbs reveals the vagueness of instructional objectives of the guide books themselves. Also, the frequent appearance of level O verbs mean that the books emphasize students recall behavior more than experimental, observational, interpretative and synthetic behaviors. Meanwhile, even the words requiring investigative activities are also mostly classified as low levels and fail to lead the students to grasp major concepts or to show original thoughts. The repeat usage of some particular words in stating instructional objectives, which is prevailing tendency of most book, exposes the monotony in instructional functions of those teacher's guides.

This study aims at identifying the characteristics of current science curriculum in several countries in terms of its format, aims and objectives, contents and guidelines. Each country has its own characteristics of science curriculum, also common characteristics among many countries. Firstly, the format of sicence curriculum in Eastern countries is very different from that of Western countries. Western countries have the curriculum format which includes characteristics and needs of science education, philosophy and background, characteristics of learner, teaching strategy and teaching materials, but Eastern countries have the curriculum format which includes only objectives, contents, and guidelines. Secondly, the aims and objectives of science curriculum in Eastern countries focus on scientific knowledges and concepts, while those of Western countries emphasize scientific methods and attitudes. Thirdly, the contents of science curriculum are very similar regardless of eastern countries or western countries. In other words, all countries included in this study emphasize biological science and earth science at lower grade level and physical science at upper grade level. Especially the observations and learning through curiosity are suggested at lower grade level, and logical reasoning is emphasized at upper grade level. Finally, the guidelines of science curriculum in eastern countries do not suggest specific information about teaching contents, experimental methods, teaching-learning activities, evaluation methods, and teaching and learning materials, while those of western countries provide more specific information about them which teachers can utilize effectively.

This study aims to present an effective basic material and data for the future earth science education by analysizing earth science curriculum of Korean high school. The method used in this study is based on comparison and analysis of the related reference materials. The main subject of this study is to find the changing history of earth science curriculum and compare the Korean earth science curriculum revised in 1982 to the American and Japan curriculums. Based on these studies following suggestions are presented for the future earth science education; 1) The laboratory education in earth science should be more emphasized than lecture. 2) It is urgent need to publish laboratory manuals for students. 3) Well designed laboratory equipments and good quality kits of reasonable price should be supplied.

An implementation study was conducted by analyzing the science curricula, surveying of the classroom activities, and the contents of the current science text books. Through this investigation, it was found that exist a discrepancies between the science curricula and current text books, the contents of the text books are just listing of informations and too hard compare the level of students activities. Furthermore, the current text books were prepared under the laboratory oriented approaching methods by emphasizing the inquiring processes. However, (at present. situations) the most schools could not carry out the objects of the current text books due to lack of instruments, laboratory facilities, and laboratory work books.
