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.

본 연구는 예비 지구과학 교사들이 가지고 있는 빅뱅에 대한 구체적인 개념을 알아보는 것을 목적으로 하고 있다. 선행 연구를 통해 다양한 대안 개념들을 갖고 있을 것으로 예상하고, 5문항으로 이루어진 개방형 검사를 적용하여 빅뱅에 대한 예비 지구과학 교사들의 개념을 조사하였다. 이 연구는 국립 사범대 4학교에서 지구과학교육을 전공하는 학생들 중 천문학 강좌를 이수하였거나 수강 중인 118명의 예비 지구과학 교사들을 대상으로 이루어졌다. 연구에서 사용된 질문지는 미국에서 수년간 천문학을 가르쳐 온 Lineweaver와 Davis가 학생들이 갖고 있는 몇 가지 공통된 대안 개념들을 경험적으로 발견하여 개발한 문항들을 번안하여 우리나라 학생들이 이해할 수 있는 수준으로 진술하였다. 예비 교사들의 개념을 조사한 결과, 빅뱅의 공간 팽창 개념에 대한 이해가 불확실하게 정립되어 있으며 다양한 대안 개념이 나타남을 확인하였다.
