The earth science was set down as a regular subject of high-school curricilum in 1956 and has been constantly transited since then. This study is to discover the theoretical basic of science education by analyzing the background of formation of the curriculum and the process of transition. The aim of this study is to give an important suggestions for the future Earth Science Education. The summary of the study and suggestions for the sixth amendment of Earth Science curriculum are as follows 1. To promote the development of Science Education, Science subjects should be decided to be a compulsory subject by authority and supported financially. 2. It is necessary that the Earth Science be selected as a required subject in both human and natural course ; at least 4 unit for the human study course, and 8 unit for the natural course. 3. In the sixth amendment of curriculum the Earth Science should be fixed as a regular compulsory subject and both experiment and practice should be reinforced.

Punch Bowl basin is analysed for the earth science and terrain factors such as geology, geophysical features, topography and water systems. The study area is composed of two kinds of rocks : Jurrasic granite in the central part and Precambrian metamorphic complex in the marginal part of she basin. The depth of the base rock is about 20 to 40 meters below the surface at the center of the basin. The process which has formed the basin may be the differential weathering of the rocks. The morphology of the slope of the basin is concave and the slope is about 20° above the nickpoint and about 5° below it. The water system of the region is very poor in drainage pattern.

The purpose of the present study is to figure out the characteristics and differences among eight textbooks of high school Science I B (Earth Science) among all currently used high school Earth Science textbooks (Science I B and Earth Science) published in accordance with the fifth amended high school curriculum by comparing and analysing the contents in them The conclusions are as follows 1. The contents of each unit are not much different among textbooks since they are written according to the curriculum ordinance and textbook guidelines of the Ministry of Education. However, the contents and the sizes of the newly introduced unit 1 on $quot;Exploration of the Earth$quot; are found to vary significantly from one to another. This unit is also found to be rather formally and inattentatively written. 2. In many instances certain identical concepts and phenomena are found to be described using different terminology in different textbooks. 3. Some physical quantities are found to be described in different ways for the identical conceps and phenomena in different textbooks. 4. The amount of pages devoted to each field is found to be ordered as follows : Geology, Astronomy, Meteorology, Geophysics, Oceanography, etc. However, the relative amounts vary significantly among different textbooks with exceptions of textbooks A and D. This is believed to be caused by preponderence of authors in certain fields instead of balanced composition. Therefore, the education authorities are urged to unify the terminology and physical quantities that are used differently for identical concept and phenomena by consulting with textbook writers and professional institutions so that efficient teaching and learning can be achieved in the school. In addition, considering the multi-science nature of Earth Science which emphasizes the interdisciplinary approach as well as the importance of Earth Science as a basic science, the textbook should be written without preponderating of certain field over others.

Research studies about students' intuitive ideas in earth science were classified into two categories, classical and actional views, according to researchers perspectives on prior knowledge. The topics of the studies reviewed here are $quot;the earth and the sun$quot;, $quot;earth science$quot;, $quot;season$quot;, $quot;air pressure$quot;, and $quot;water in the atmosphere.$quot; Several intuitive ideas showed quite strong stability across task context. Cultural influence on a few intuitive ideas were reported and should be studied further. Students may commonly hold various intuitive ideas about some instruments used for instruction. For example, humidifier may be used for the relative humidity class. Students views about humidifier seems to be quite different from those of the teachers, and should be studied further.

One of fundamental bases for the desirable Science Education is effective evaluation, and the objectives of the Science Education can be used for the reasonable basis of this evaluation. In this paper, to study the current state of the high school Earth Science Education, comparison was made between the objectives of Education proposed by textbook and those to be measured by Scholastic Achievement test, and the result was analyzed. 1. The objectives of both the textbook and Scolastic Achievement test are highly oriented to obtain theory and comprehension. 2. The objectives which measure the Process of Scientific Inquiry are to some extent satisfied by the textbook but not by the Scholastic Achievement test. Consequently the future evaluation process should be modified in order to evaluate properly the ability for the process of Scientific Inquiry of the students properly.

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.

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 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.
