The purpose of this exploratory study was to investigate the influence of pre-service science teachers' selection of earth science I, II in the high school and their college major on their self-perceived attitude and academic achievement in general earth science lecture at university. The participants in the study were 273 who enrolled in the division of science education, college of education and took the general earth science lecture from 2012 to 2015. The data was analyzed with two-way ANOVA by using SPSS 23.0. The results indicated that there was no significant difference of students' attitude and examination difficulty in general earth science lecture between earth science major and other subject major. However, students who took earth science I and/or II in high school showed positive attitude toward the lecture and higher achievement scores than students who didn't take earth science I, II in their high school. The results of the study imply that it is essential to consider students' attitude toward science and achievement in pre-service science teacher education.

Both Earth science II and Korean geography textbooks emphasize the importance of content related to 'geology of the Korean Peninsula'. This study aimed to analyze the differences in the content related to the 'geology of the Korean Peninsula' presented in the textbooks, and to find out whether these differences are consistent with the latest scientific knowledge in any inconsistencies are found. For this purpose, seven textbooks (four Earth science II and three Korean geography) published under the 2015 revised curriculum were selected as the subject of analysis, and the difference in the description of the tectonic provinces of the Korean Peninsula, geologic time scale, and explanatory texts of geological characteristics between Earth science II and Korean geography textbooks were compared. As a result of the analysis, there are some cases of inconsistencies between Earth science II and Korean geography textbooks in terms of terminologies, names, and distribution ranges related to the tectonic provinces of the Korean Peninsula. The Korean geography textbooks had inconsistencies in the geochronologic data of the rocks as they cited outdated data. In addition, inconsistencies were found in the explanatory texts describing the 'distribution of rocks on the Korean Peninsula', 'characteristics of the Pyeongan Supergroup', and 'great hiatus of the Paleozoic Era'. Both Earth science and Geography have many concepts in common, therefore, effort is needed to minimize the differences in content. It is important to select the content appropriately which should reflect the latest scientific knowledge and presents the concepts consistently.

Numerical data of the geological time scale in Earth Science I, II textbooks and those of University textbooks of Korea and other countries are briefly reviewed. Numerical data of the geologic time scale shown in Earth Science I, II textbooks are mostly out of date and many of them follow those in the University textbooks of Korea. The same situation is apparent for introductory Earth Science or Geology textbooks of other countries as old data exist in their text books as well. There are many new data in the International Stratigraphic Chart (ISC 2000) and International Geologic Time Scale (IGTS 2003) recently updated by International Commission on Stratigraphy (ICS) and A Geologic Time Scale (GTS 2004). Among the new data, some important things are Paleogene and Neogene Periods of Cenozoic Era, Mississippian and Pensilvanian Epochs of Carborniferous Period, Paleoproterozoic, Mesoproterozoic, and Neoproterozoic Eras of Proterozoic Eon, and Eoarchean, Paleoarchean, Mesoarchean, and Neoarchean Eras of Archean Eon. These new data should be used in the new Earth Science textbooks.

제7차 교육과정에 따라서 집필된 지구과학 I, II 교과서와 국내외 각종 지구과학 교재의 지질 연대 자료를 검토하였다. 지구과학 I, II 교과서의 자료는 대부분 최신의 자료가 아니며, 많은 자료들은 지질학 원론과 지구과학 개론 등의 국내 대학 교재에 제시된 수 십년 전의 자료를 그대로 따랐다. 또한 외국 대학의 지구과학 또는 지질학 개론서의 경우에서도 유사하게 수 십년 전의 자료를 제시하고 있다. 최근 국제 층서 위원회(ICS)에 의하여 연구 제시된 국제 층서 챠트(ICS 2000), 국제 지질 연대표(IGTS 2003) 및 지질 연대표(GTS 2004) 등의 많은 새로운 자료들이 제시되어 있다. 새로운 자료 중에서 중요한 것들에는 신생대의 고제3기와 신제3기, 석탄기의 미시시피아세와 펜실베니아세, 원생이언의 고원생대, 중원생대 및 신원생대 그리고 시생이언의 시시생대, 고시생대, 중시생대 및 신시생대를 들 수 있다. 이들 새로운 지질 연대 자료는 새로운 지구과학 교과서 집필시 인용되어야 할 것이다.

This study investigated the trends in the number of applicants and mean score and applicants’ responses on the test items of Earth Science in the College Scholastic Ability Test (CSAT) implemented for 3 years (1999-2001). The percentage of applicants of science track were 43.14% in 1995, but reduced through 29.5% in 2001 to 26.92% in 2002 CSAT For elective subject, about 22% of science track students applied to Earth Science II which ranked third to Biology II and Chemistry II. In 1999, test items were developed to have the expected difficulty 40 ${\sim}$ 59% (6 items) to 60 ${\sim}$ 79% (10 items). But in 2001 every 16 items were developed to have difficulty 60 ${\sim}$ 79%, which was caused by the policy of so called ‘easy CSAT’. Thus the mean score of ‘Earth Science II’ was increased from 50.26 in 1999 through 64.47 in 2000, to 67.58 in 2001. Applicants were generally very good at solving test items focusing on process skills only and familar items but poor at solving test items related to the motion of the earth and planets and sea wave, especially items calling two or more concepts. Thus special measures to cope with the decrease in applicants of science track should be provided. And it is recommended to develop test items with wider range of difficulty and to reduce test items calling process skills only. And special consideration should be given to teaching the content area with poor achievement and high actual difficulty compared to the expected.

In this study, searched how science museum reflects personality of course of study and target comparing display contents of science museum with high school earth science Ⅰand Ⅱ of the 7th curriculum. Result of this study is as following. First, area that earth science contents of course of study are exhibited has been less than 50%, and is preponderated by unit. Second, earth science course of study reflection degree of science museum is middle.(2.8 points of perfect score 5 points) Third, number of average mark of contents that is exhibited by science museum in significance level 0.05 lows is difference, and it is no difference by unit.

On the basis of Sternberg's theory of mental self-government, this examined the difference in thinking style between gifted science students and non-gifted students, and their earth science concepts by the different types of thinking styles. The subjects were consisted of 120 students from the Busan Science Academy and 122 students from two general high schools in Busan, Korea. All participants responded to the Thinking Styles Inventory which is a self-report test consisting of 65 items, and essay questions for examining the students' earth science concepts. The results are as follows. First, the gifted science students prefer legislative, judical, anarchic, global, and liberal styles, where non-gifted students prefer executive, oligarchic, and conservative styles. Second, Type I thinking style group prove to have more complex concepts in relation to the geological and astronomical areas than those of the Type II thinking style group in both of the gifted and non-gifted students. This indicates that Type I thinking style students use a deep learning approach where Type II thinking style students use a surface learning approach.

This study is the analysis of the effects of Jigsaw II Cooperative Learning upon the academic achievement and upon the ability of self-directed learning, compared to lecturing. It made it experimental target for two male and two female classes of students in the 2nd grade of humanity high school in Ulsan metropolitan area. One male and one female classes conducted Jigsaw II cooperative learning by making up a small group heterogeneously from the aspect of learning ability, and the other male and female classes carried out the lecturing focusing on a teacher. As for the academic achievement of science, Jigsaw II cooperative learning was shown to be effective compared to the lecturing. As for the ability of self-directed learning, Jigsaw II cooperative learning was indicated to be effective compared to the lecturing. As for the ability of self-directed learning for Jigsaw II cooperative learning, it was indicated to be effective compared to the lecturing. Given seeing this, it was identified the necessity for Jigsaw II cooperative learning to be applied to a school field as an alternative plan for the lecturing.
