The purpose of this study is to analyze high school chemistry curricula in Korea and China in order to identify possible implications for the improvement of the Korean curriculum. The school curricula of Korea and China had been developed by the Ministry of Education of both countries as national curricula. The 1996 Chinese high school chemistry curriculum, and the 7th Korean high school chemistry curriculum announced in 1997 were compared in respect to the characters, objectives, history, time allotment, structure, subject contents, and assessment plans. Based on the comparative analysis of the curricula, some of the ideas, which provide implications for the improvement of Korean chemistry curriculum, were identified. The identified ideas were elaborated to seek directions for the solutions of current problems in chemistry curriculum. such as common science subject. tentative implementation of curriculum, compulsory provision of chemistry, subjects in science course, enlargement of curriculum, and methods of assessment.

The purpose of this study is to compare and analyze the science curriculum of Korea and Estonia with a focus on the chemistry domain, and draw implications for reference when revising the next curriculum. To this end, the overall curriculum design centered on science subjects and the core concepts of chemistry covered in subjects corresponding to the common curriculum of the two countries were compared. As a result of the analysis, first, Estonia specifically suggested how the core competencies suggested in the general lecture were specifically connected to science subject. In addition, there was a characteristic that the inquiry function, attitude, and value were specifically presented in the curriculum document. Second, as a result of analyzing the core concepts of chemistry, most of the concepts dealt with in Korea were also dealt with in Estonia. However, Estonia has a tendency to deal more qualitatively with broader concepts. The concepts covered in the chemistry subject exceeded the level of the common curriculum in Korea, but this subject also had the characteristic of attempting a qualitative approach.

The purpose of this study is to analyze the relationship between the eight topics in TIMSS 2019 8th grade chemistry domains and the Korea 2009 Revised Science Curriculum and the 2015 Revised Science Curriculum. For this purpose, four elementary and four secondary teachers participated in physics, chemistry, biology and earth science majors, and two science education experts participated in analyzing in which grades the content elements of the TIMSS 2019 science framework are covered in the Korean science curriculum. The study also analyzed whether the content of the Korean science curriculum matches the 246 items of 8th grade in the TIMSS 2019 assessment and reflects in which grades the eight topics are covered. The results of this study are as follows. First, among the TIMSS 2019 evaluation topics, topics not covered at all in the Korean middle school curriculum were periodic table, matter and energy in chemical reactions, the role of electrons in chemical bonds. Second, the topic of "the periodic table as an organizing principle for the known elements" needs to be introduced in the Korean middle school curriculum, and topics such as "familiar exothermic and endothermic reactions" and "factors affecting the reaction rates" need to be discussed in consideration of the flow of international curricula. Third, the next science curriculum should be structured so that the sequence of chemistry contents and scope, especially core concepts to be included in the elementary, secondary, and higher education curriculum is linked to continuity.

This study compared and analyzed the chemistry curriculum of South Korea and Singapore. The analysis revealed that Korea's achievement standards in the chemistry subject comprised knowledge and skills, whereas Singapore's achievement standards comprised knowledge, skills, values, and attitudes. The scope of knowledge and skills of the Singaporean achievement standards-wherein each element was explicitly presented-were more extensive than that of Korea. The elementary school curriculum in both countries was structured to help students qualitatively understand materials in real life, whereas the middle school content was structured such that students could understand the topic of particles. Additionally, several differences were found in specific content elements; for example, the periodic tables were included only in the Singaporean content, whereas changes in the volume of gas according to temperature and pressure were included only in the Korean content. The Singaporean academic achievement standards, integrating knowledge, skills, values, and attitudes in science curriculum, can be used as a reference for adjusting and restructuring the Korean curriculum.

This study was to analyze the educational objectives of evaluation of practice quizzes and learning objectives of chemistry I textbooks for the 2009 revised curriculum by Klopfer's taxonomy. The result revealed that the objectives of science education indicated in the 2009 revised curriculum were contained the educational meaning of all categories except 'manual skills' of Klopfer's taxonomy of educational objectives. The learning objectives of chemistry I textbooks laid mostly on 'the knowledge and comprehension' and 'the process of scientific inquiry'. It showed that 'the objectives of scientific knowledge and methods', 'manual skills' and 'scientific attitude and interest', 'orientation' seemed to be taken in a relatively careless way. The result on the practice quizzes in textbooks, they also laid stress on 'the knowledge and comprehension' were covered much, even though they were emphasized in the other objectives of the curriculum. It was concluded that the educational objectives of the science textbooks did not reflect much on educational objectives of the 2009 revised curriculum.

purpose of this study was to analyze high school chemistry teachers perception of the Chemistry I & Chemistry II in the 7th national curriculum and their demands on the revision of curriculum. A nationwide survey was administered to obtain the responses from 108 high school chemistry teachers. More than half of the participants thought the current curriculum of Chemistry I and Chemistry II needed revising. As the results, a major drawback of Chemistry I was a difficulty in explaining phenomena due to absence of basic concepts, and that of Chemistry II was an excess of the contents for high school science courses. Unfortunately, it was found out that inquiry activities existed only in name, especially in case of Chemistry II. Regarding the manner of content organization of Chemistry I in new curriculum, demand on a concept-based approach outnumbered theme-based approach. For revising Chemistry, the majority of participants demanded basic chemistry concepts to be introduced, without supplementation of quantitative approaches and deepening level of concepts. An urgent request for Chemistry II was reducing content by shifting relevant concepts to Chemistry I. Implications for high school chemistry education including revising curriculum were discussed.

The purpose of this research is to estimate the chemistry teacher's perceptions of Chemistry I course based on the 7th national curriculum through actual class teaching situations and interviews and teaching guidance of an actual class through a lesson and an interview. For this research, four chemistry teachers who have had an experience teaching the chemistry I course were selected. As the results of the research show, chemistry teachers had the correct understanding of the purpose of the Chemistry I course, but they were teaching the concepts of Chemistry II . They thought the reason for the teaching was the national scholastic aptitude test. But according to analysis, the contents of the previous tests were hardly beyond the limit of Chemistry I course. For this research, the chemistry teachers looked for the purpose of Chemistry I course based on the 7th curriculum only at the superficial views, and the teacher's wrong understanding about the tests disturbed the revelation of the spirit of Chemistry I course of the 7th national curriculum.

The purpose of this study is to compare the contents of chemistry textbooks developed according to the 2015 revised curriculum with the contents of the 2009 revised curriculum to research the change in "the development and use of models". To do this, we analyzed 8 kinds of Chemistry I textbooks and 6 kinds of Chemistry II textbooks from the 2015 revised curriculum and compared them with 4 kinds of Chemistry I textbooks and 4 kinds of Chemistry II textbooks from the 2009 revised curriculum. The scope of the analysis was the explanations of the textbooks related to aqueous electrolysis experiments. In order to compare the contents regarding electrolytes when the same experiments are interpreted with different models, we analyzed contents of 4 kinds of middle school science textbooks from the 2015 revised curriculum and 9 kinds of middle school science textbooks from the 2009 revised curriculum. As a result of the analysis, the same experiment was explained by different models according to the grade level and unit, and all explanations were limited to a single model. Also, the tendency to limit the kinds of electrolytes for controlled experimental results is more pronounced in the 2015 revised curriculum than in the 2009 revised curriculum. From this results, we suggest that efforts are needed to reflect the "development and use of models" in chemistry textbooks developed according to the 2015 revised curriculum.

The purpose of this study was to analyze chemistry textbooks and teachers' guidebooks from the perspective of 'Ignorance', one of the important features of model. This is because the emphasis is on developing modeling capabilities for students in the 2015 Revised Curriculum. For this, Arrhenius model and Brønsted-Lowry model were selected as acid and base models in neutralization reaction which are important contents in chemistry curriculum. The analysis criteria of this study were extracted by analyzing previous studies and four general chemistry textbooks dealing with 'Ignorance' related to acid and base neutralization reaction. Based on the analysis criteria, we analyzed nine chemistry I textbooks and teacher's guides and six chemistry II textbooks and teacher's guides of the 2015 revised curriculum. In addition, we analyzed contents of four chemistry I textbooks and teacher's guides and three chemistry II textbooks and teacher's guides in the 2009 revised curriculum for comparison according to revised curriculums. We analyzed the contents related to the concept of 'neutralization reaction', 'neutrality', 'quantitative relation of neutralization reaction', 'degree of ionization', and 'ionization constant'. Based on the results of this study, we proposed a way to present 'Ignorance' of the models in teachers' guidebooks that chemistry teachers can understand 'Ignorance' of model and teach modeling capabilities for students.
