By definition, geophysics is the application of the principles and practices of physics to the solution of problems related to the earth. American Geophysical Union classified geophysics into eight subdivisions, namely meteorology, hydrology, oceanography, seismology, volcanology, geomagnetism, geodesy arid tectonophysics. The science of geophysics came into being as a result of the need of the geologist for new tools. Every earth scientist, especially the geologists, should be familiar with the various ways in which geophysics can help him understand the earth. Geophysical exploration may be defined as prospecting for oil, natural gas, mineral deposits and geologic structures by surface measurements of physical quantities. Geophysical exploration methods may be broadly classified under two beadings: major and minor. There are four· maior geophysical methods; gravitational, magnetic, seismic and electrical, and six minor methods; acoustic, dynamic vibration test, strain ganging, geothermal detection, gas detection and radioactivity mesurement. At present, the greatest use of geophysical exploration is male in oil exploration. It is also broadly used in the mining industry. A third major field for geophysical work is that of engineering, encompassing civil engineering, engineering geology, and allied fields such as mililary, structural, gas, and pipe-line engineerings, and the like. Geophysics and geophysical exploration, as new branchs of earth science have shown outstanding development in the fields of theory, exploration equipment, exploration technique and data interpretation. The development of computer and data processing technique have done a great role in the development of geophysics. As long as man has desire to understand the earth, and to seek the natural resources for his own existence, he should perceive the necessity and merit of geophysics, and also should do his best to develope it.

Since 1968, earth science has been a compulsory course in high school, along with physics, chemistry and biology. Our nation's current auricular was prepared in 1963 with the sprit of John Dewey's theory of education, it emphasized the science of life and science of production but not science as science itself. The present movent to amend science curricular has seen the publication of PSSC physics, CHEMS chemistry and BSCS biology text books. These were the textbooks in line with the new ideas on science education emphasize the followings: 1) Science as inquiry 2) Basic concepts, theories and investigations of the interactions among the natural phenomena The earth science curriculum project (ESCP) organized for the purpose of writing a new earth science textbook and preparing other educational meterials that would bring the earth science curriculum into conformity with the new movement in science education. The amendment of the present korean earth science curriculum is a matter of necessity and urgency for the following reasons, 1) The national charter of education calls for sweeping reforms of nations education. 2) The modernization of Korea is impossible without rapid advance in natural science and technology. 3) The present curriculum is very far from conformity with the spirit of science education 4) Changes in korean educational system demend corresponding changes iff curricula to be taught The purpose of this study are to gain an understanding of the new spirit in earth science education, to identify the differences between ESCP and the present korean earth science curriculum, and this to determine what need to be corrected, in preparing a better earth science curriculum and textbook. As a result of the study, the author concluded that: 1) There is an urgent need to prepare a better textbook and curriculum in earth science 2) The revised curriculum must be designed te emphasize science as science itself and to help achieve the national goal of education in Korea as set forth in the national charter of education 3) The present earth science textbook with its emphasis on technology and de-emphasis on the process of science, failed to show the structure of knowledge of earth science. The new textbook must make greater efforts to show the structure of scientific knowledge and interrelationship among physics, chemistry, biology and earth science. 4) The revised curriculum should contain laboratory work, which is inevitable in helping the students to develope intuitive thinking, inquiry and active studying process.
