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.

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 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 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.

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.

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.
