Earth Science under the rapid development is so necessary for Various majors of students that the curriculum of Earth Science should Be widely studied and applied for training of science teachers as well As for general education. It is essential that university authorities support Earth Science education and understand its importance. Furthermore the followings are to improve Earth Science education. Textbook must be written in connection with the high school Curriculum. Laboratory equipments and facilities should be expanded. Develpoment and exploitation of A V materials should be demanded.

The purpose of this study is to consider pre-service and in-service elementary school teachers` beliefs about STS (Science-Technology-Society), by investigating their opinions on STS interactions. 222 of the seniors in Jinju National University of Education, namely pre-service elementary school teachers, and 185 of the active teachers in Kyung-Nam Province were selected as the objects for researching these matters. Their beliefs about STS interactions were examined. The results were analyzed with a percentage as an examining tool of TBA-STS(Teachers` Beliefs about Science-Technology-Society). The results were as follows; First, on the nature of science, most of them showed simple opinions. On the nature of technology, most of them also showed simple opinions. most of them recognized the interactions among science, technology, and society affirmatively. They showed simple opinions on the interactions between science and technology. In fact, they didn`t recognize the interactions between science and society, but they knew the influence of technology on society relatively concretely. Second, if one consider the cognitive situation or the distributing route of STS, he can easily find that most teachers never or little know it. At present, pre-service teachers learn STS from the lectures in their universities, and in-service teachers get information about it from science magazines/newspapers and training.

The purpose of this study was to examine whether or not they have been revised corresponding to the purpose of revision by making a comparative analysis of the content and illustration in the 6th and 7th primary science textbooks. The analysis of content was composed of knowledge, inquiry process and attitude. The analysis of illustrations was composed of the kinds of illustrations and the role of illustrations. The findings of this research were as follows: First, as a result of content analysis of the primary science textbooks in the 6th and the 7th national curriculum, the ratio of inquiry process showed the highest frequency, next knowledge and lastly scientific attitude. And the 7th textbooks are greatly emphasized knowledge and science attitude. Second, as a results of the illustration analysis are as follows: There are conspicuous differences in that the illustration number of the 7th science textbooks is about twice the illustration number of the 6th science textbooks and next, they place more weights on pictures and comics hard to discovery in the 6th science textbooks. Therefore, they have tried to induce the interests of students and heighten their understanding by supplementing the role of illustration presented as picture-centered and increasing its number presented as picture. In the results, although they have improved the problems of the 6th national curriculum a lot through the innovation including the interest induction of pupils through comics, the development of its content presentation method, the gradual change of subject number and the cultivation of curriculum according to the level of enrichment and supplementing types, the 7th science textbooks have fallen short of 6.3%, not around 30% in terms of the reduction in the 7th national curriculum. Accordingly, the 7th science textbooks also can be pointed out to have the problems of too much amount of studying compared to the time per week like the 6th science textbooks.

This paper aims to find out how did elementary students understand scientific units in science textbooks. The subjects were 191 students of the 6th grade from 7 elementary schools in 3 different areas, consisting of 70 from 4 village schools of, 64 from 2 town schools of Gyeongnam province, and 57 from one city school in Ulsan Metro City. A test was developed based on the analysis of scientific units in the science textbooks and teacher`s manuals constructed according to the 6th and 7th National Science Curriculum. The understanding of elementary students` on the scientific units(Temperature, Length, Weight, Volume, Speed, Plane Angle)were surveyed. The result are as follows: Regarding the temperature unit, the students generally well understand why to measure and how to read temperature, but had some problem in recording it, in confusion with the plane angle sign. As for the length unit, they obtained high scores in understanding the purpose of measuring length as well as recording and reading it. Which indicates that they are well aware of and use the unit appropriately. With respect to the weight unit, they got high scores in reading and recording weight, which means most students have no problem using the unit. However, it was found that they do not understand why to use the plate balance scale. The unit of speed is the most difficult one for children`s of science to understand, presumably, because it is an derived unit from two basic units. It is also assumed that the students got the highest score in the plane angle unit because they studied the unit immediately before the test. From the children`s understanding of science units above the teacher`s understanding and teaching methods presumed to play a major role for children to understand and use the science units properly.

남해안 통영시에 분포한 상부 백악기 고성층에서 산출된 공룡 알 화석을 Macroelongatoolithus goseongensis oosp. nov.와 Dictyoolithus neixiangensis로 기재하였다. M. goseongsis는 길이가 39 ㎝에 이르는 크고 신장된 공룡 알화석이다. 신장 지수(elongation index)는 0.3이고 알 껍데기의 두께는 2.3-3.1 ㎜이다. 연속층과 유상층의 비는 4.8:1이다. M. goseongsis는 M. calylei와 연속층과 유상층의 비가 다르며, M. zhangi와 크기, 신장 지수 및 연속층과 유상층의 비가 다르고, M. xixiaensis와는 신장 지수와 연속층과 유상층의 비가 다르다. D. neixiangensis는 120 ㎜의 직경을 갖는 둥근 공룡 알 화석이며, 알 껍데기의두께는 1.5-1.7 ㎜이다. 알의 외부 표면은 입상으로 매끄러운 상태이다. D. neixiangensis는 두개 또는 세개의 알 껍데기 단위(eggshell units)가 중첩된 불규칙한 망상 구조를 보이는 알 껍데기의 기본 미구조(basic microstructure)가 특징적이다. M. goseongnsis는 Macroelongtoolithus의 네번째 oospecies이며, 이 oogenus의 고생물지리적 분포를 확장시키는 증거이다. 또한 M. goseongnsis의 산출은 M. goseongnsis의 주인공으로 생각되는 오비랩토사우루 또는 오비랩토사우루와 유사한 수각류 공룡이 백악기의 경상 분지에 서식하였음을 지시한다. 상부 백악기(Campanian)의 고성층에서 산출된 Dictyoolithus neixiangensis는 Dictyoolithus의 표식지인 남동 중국 해난 이외의 지역에서 처음으로 기록된 것이며, 이 알 화석 종류의 층서적 산출 범위를 전기 백악기에서 후기 백악기로, 그리고 고생물지리적 분포를 남동 중국에서한국으로 확장하는 증거를 제공한다. Dinosaur eggs found from the Upper Cretaceous Goseong Formation of Tongyeong City, southern coast of Korea are herein described as Macroelongatoolithus goseongensis oosp. nov. and Dictyoolithus neixiangensis. M. goseongensis is large (39 ㎝ in length), elongate egg. Elongation index is 3.4 and shell thickness is 2.3-3.1 ㎜. Continuous layer to mammillary layer ratio ranges up to 4.8 : 1. M. goseongensis differs from M. carlylei in continuous to mammillary layer ratio, from M. zhangi in egg size, elongation index, and continuous to mammillary layer ratio, and from M. xixiaensis in elongation index and continuous to ma㎜illary layer ratio. D. neixiangensis is a spherical egg with a diameter of 120 ㎜. Shell thickness is 1.5-1.7 ㎜. Outer surface of egg is smooth with grainy forms. It is characterized by basic microstructure of eggshell which displays irregular reticulate composed of two or three superimposed eggshell units. M. goseongensis represents fourth oospecies of Macroelongatoolithus and provides an evidence for extending paleobiogeographic distribution of this oogenus. Occurrence of M. goseongensis also suggests oviraptosaur or oviraptorosaur-like theropod, possible maker of M. goseongensis, lived on the Gyeongsang Basin of Korea during the Cretaceous. Occurrence of Dictyoolithus neixiangenesis from the Upper Cretaceous (Campanian) Goseong Formation represents the first record of Dictyoolithus outside of type locality, Henan, southeast of China and provides an evidence for widening its stratigraphic range from Early Cretaceous to Late Cretaceous and its paleogeographic distribution from southeast China to Korea.
