We fitted latent growth models of attitude towards science using the Korea Education & Employment Panel 2004-2007 data with 343 high school students. The growth model show better fit indices compared to the no growth model. The intercept and slope showed significant variances, and thus, we added control variables of the number, ratio of advanced courses, and variety in science elective subjects, and the achievement percentile for middle school. In the conditional growth model, the previous achievement has significant positive effects on the intercept and the ratio of the advanced courses and variety of science subjects show significantly positive effects on the slope. Based on the results, it supports the 2022 Revised Science Curricular that high school credit system should provide students with basic 'Physics,' 'Chemistry,' 'Biology,' and 'Earth Science,' credits in 'general electives', various integrated subjects in 'converged electives', and highly advanced subjects in 'career electives.'

The purpose of this study is to survey the status of the 7th elective-centered curriculum and find problems in operating the system. 485 students in the tenth and eleventh grade were randomly selected as subjects. The results are as follows. (1) Among the students, 29% of them selected their science subject without considering their future jobs, 48% did it without enough overview of the system, and 25% did without clearly understanding the details the choice centered curriculum. (2) Among the students who participated in the survey, 65% of them showed positive responses concerning the needs of individual choice centered curriculum and 96% said it increased their participation in class. However, only 39% believed that operating this type of curriculum is realistically possible. (3) 89% of students selected their science subjects accordingly with the college preparatory courses and 14% selected based on their hopes. (4) The percentage of science subjects chosen are 40% for chemistry, 25% for biology, 22% for Physics, and 13% for earth science, but 74% of students wanted to change their choices. These results showed that students recognized the object of the 7th curriculum, but selected science subjects as a means of getting into college entrances, rather than carefully considering their future and aptitude.

In this study, we investigated the elements of knowledge and information processing competence of science inquiry activities in grades 3-6 science textbooks. For this purpose, the elements of knowledge and information processing competence were extracted and a framework for analysis was created. Analysis of eight science textbooks for grades 3-6 in elementary school was carried out using the analysis framework. The following results were obtained by the analysis framework: First, we divided the knowledge and information processing competence into five elements: 'collection,' 'analysis,' 'expression,' 'selection,' and 'evaluation.' Second, the elements of knowledge and information processing competence of science inquiry activity of elementary science textbooks were not evenly composed. The science inquiry activities of elementary science textbooks focused on 'collection' and 'analysis' among the five elements of the knowledge and information processing competence, followed by 'expression,' 'selection,' and 'evaluation.' As a result, we found that a science inquiry model or a science instruction model is needed to develop the knowledge and information processing competence in elementary school science curriculum.

The purpose of this study is to compare the concepts and inquiry activities of textbooks in Korea and Singapore textbooks focused on the field of geology, and to provide implications for the future development of Korean curriculum and textbooks. For the study, it was selected as the 2015 revised science textbook in Korea and 'My pals are here' that is the most used textbook in Singapore. The results of this study are as follows: First, Korea had a lower level of concept than Singapore. Second, we could confirm that Korea is composed of 'inquiry' centered compared to Singapore. Third, Korea deal with only one concept in one grade, however Singapore is structured so that concepts are divided hierarchically into several grades. Fourth, Singapore has been instructing students to learn how the learned concept interact with the Earth, which is different from Korea. These results may give implications for the curriculum composition and textbook development in Korea.

The purpose of this study was to investigate high school students' perceptions on chemistry subjects: reasons for choosing chemistry, learning volume and content difficulty, interests, teaching/learning methods, preferable classes etc. A total of 1,087 students who took chemistry subjects at 126 high schools by proportional stratified sampling were voluntarily participated in the survey. The main reasons the students chose chemistry subjects were interests and interests in chemistry, foundation to science, relevance to college majors, and so on. Students recognized that the learning volume and content difficulty as normal level was about 60%. Reasons why chemistry was difficult was that, although there was a difference in degree, chemistry was difficult in itself and had too much things to memorize. In the case of interests in chemistry subjects, students of 43.9% of Chemistry I and 52.0% of Chemistry II recognized the level as normal. The reason why not interested in chemistry subjects was that it was the nature of chemistry contents, or students had neither interests and enjoyment of chemistry nor foundation for chemistry. Classes were mostly lectures but the students preferred mainly experimental activities, or explanation with real-life examples or science stories. The frequency of experimental activities was found to be 1 to 5 times per semester, or not experimented. Research and efforts will be necessary to improve classes and environments for students' experimental activities.

Science textbook is the most frequently used teaching material in elementary schools of the United States and Korea. Elementary science textbooks of the United States and Korea are analyzed to find out the educational objectives and characteristics of contents shown in textbooks. About 100 pages each in the first grade and fourth grade science textbooks each nations are selected randomly for educational objective analysis. Life science contents of 1st to 6th grade are analyzed from elementary science textbooks of the United States and Korea. The analyzed textbooks in Korea are 'Wise life,' an integrated subject with social studies and science, and 'science.' The analyzed elementary science textbooks of the United States are Harcourt Science, which is one of the frequently used textbooks. The educational objective framework used includes science knowledge, scientific inquiry, scientific attitude, STS, and philosophy and history of science. The results show science textbooks of the United States emphasize scientific knowledge more than scientific inquiry. Korean science textbooks emphasize scientific inquiry more than scientific knowledge. Elementary science textbooks of the United States present some life science topics redundantly and expose more difficult topics than Korean.

This study compared junior high school science textbooks(for grade $7{\sim}9$) of the USA, Australia, Japan, and Korea. Specifically, the amount and pattern of knowledge, process skills, activities, contexts, nature of science, and integration topics were compared in terms of country, grade, and content. The results of analysis are as follow: 1) Physics, chemistry, biology, and earth science were equally distributed in textbooks of Korea and Japan. In Korean textbooks, "law" was more emphasized compared with other countries' textbooks. 2) The most popular process skills were proportion and controlling variables in Korea's textbooks. Correlation, cause/effect, and proportion in Japan's textbooks. Controlling variables and data transformation in textbooks of USA and Australia. 3) Experiment and observation were the most popular activities in textbooks of Korea, Japan, and Australia. In textbooks of the USA, observation, experiment, survey, practice, and measurement activities were used evenly. 4) In textbooks of Korea and Japan, pure science and natural environment contexts were the most popular. 5) There was no chapter dealing with nature of science in textbooks of Korea and Japan. 6) Integration topics between science and technology were the most popular. Based on these findings, several implications on Korean science textbooks were discussed.

The purpose of this study is to explore ways to change high school earth science elective courses with the introduction of the high school credit system in 2025, and ways to restructure them in preparation for the next curriculum revision. For this purpose, Delphi surveys with earth science education experts, a survey with in-service earth science teachers, and in-depth interviews with experts were conducted. According to the results, we need to consider four keywords such as cultivation of earth science literacy, connection with student career paths, emphasis on the fun of earth science itself, and student selection rate and college entrance exam in restructuring Earth science electives. Based on this direction, we composed four subjects: Earth System Science emphasizing earth science literacy, and three such subjects reinforcing career connection as Solid Earth Science, Atmospheric and Ocean Science, and Space Science. To resolve concerns about falling selection rate of earth science courses with the introduction of the high school credit system, it is necessary to re-establish the status of the earth science subjects including enhancing the career connection of the earth science electives. Follow-up studies are necessary to elaborate and publicize the titles and core concepts of Earth science electives.

Unlike Korean science curriculum's continued push for "relevance of contents" to reduce the burden of learning on students, IB DP (International Baccalaureate Diploma Programme) is chosen in many countries and the number of IB world schools continues to grow, although it contains not only a large amount of learning but a substantial amount of content that requires quantitative calculations. Through this study, we suggest implications for Korean science curriculum and textbook, by comparing the constructions of chapters, the achievement standards, the learning contents, and the formulas of physics textbook, focusing on the 'relativity' unit of the 2015 revised national curriculum and IB DP, and by analyzing the questions of college scholastic ability test (CSAT) and external assessment (EA).
