  • 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 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.

  • 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.

  • In this study, the contents of the electron transfer model presented in the 4 chemistry I and the 4 chemistry II textbooks of 2009 revised curriculum and 9 chemistry I textbooks and 6 chemistry II textbooks of 2015 revised curriculum were analyzed in the viewpoint of model's Ignorance. In addition, 3 questions were developed to find out whether 24 pre-service teachers were perceived of the Ignorance of the electron transfer model. As a result, Most textbooks explain the redox reaction of covalent bond substances, which is an inconsistent context of the electron transfer model, with mixing oxidation number change and electron transfer or with electron transfer. In addition, the change to the development and use of the model emphasized in the 2015 revised curriculum was not clearly revealed in the curriculum comparison. Most pre-service teachers incompletely perceived or did not perceive Ignorance of the electron transfer model. Only 1 pre-service teacher perceived Ignorance of the model. In conclusion, the textbook description needs to be improved so that Ignorance of the model is revealed when the textbook describes the inconsistent situation of the electron transfer model. And through the education for pre-service teachers, it is necessary to provide an opportunity for pre-service teachers to perceive Ignorance of the electron transfer model.

Analysis of Curriculum and Textbooks of Chemistry I and Survey of Chemistry Education Major Teachers' Conceptions Related to Electron Movement Model and Oxidation Number Change Model (전자 이동 모델과 산화수 변화 모델에 대한 화학 I 교육과정과 교과서 분석 및 화학교육전공 교사들의 인식 조사)

  • In this study, we analyzed the descriptions of the electron movement model and the oxidation number change model presented in the 2009 revised curriculum and textbooks. We also investigated chemistry education major teachers' conceptions of limitations of each model. The electron movement model and oxidation number change model were presented in the curriculum and the textbooks. However, hybrid model was also presented which fail to grasp the limitation of each model. The hybrid model explains redox reactions of covalent bond compounds by electron movement model or even if it explains redox reactions by oxidation number change model, this explanations have the problem of confusing the virtual electron movement with the actual electron movement. A questionnaire and interviews were conducted to investigate chemistry education major teachers' perceptions of redox reactions. As results, many teachers did not recognize the limitations of each model and had difficulties to distinguish redox reactions from acid-base reactions because of the hybrid model.

  • The purpose of this study was to investigate the inscription of North Korean Higher-Level Middle School 1 chemistry textbooks in the era of North Korean leader Kim Jong-un to understand North Korean chemistry education. The types and functions of inscription for each unit of the North Korean Higher-Level Middle School 1 Chemistry textbook were analyzed and compared with the inscription of the 'Chemistry I' textbook in South Korea. Inscriptions were analyzed by constructing an analysis frame based on previous studies. The analysis results were as follows. First, as for the types of inscription used in North Korean textbooks, photographs and illustrations were used the most, and graphs were used the least. Second, the functions of inscription used in North Korean textbooks had many exploratory and exemplary functions, and decorative functions were used the least. Third, there was no significant difference in type and function of textbook inscriptions from North and South Korea. The results of this study may be helpful in understanding North Korean chemistry education.

Analysis of Problems in the Submicro Representations of Acid·Base Models in Chemistry I and II Textbooks of the 2009 & 2015 Revised Curricula (2009 개정교육과정과 2015 개정교육과정의 화학 I 및 화학 II 교과서에서 산·염기 모델의 준미시적 표상에 대한 문제점 분석)

  • We analyzed the representations of acid-base models in 4 kinds of Chemistry I and 4 kinds of Chemistry II textbooks of the 2009 revised curriculum, and 9 kinds of Chemistry I textbooks and 6 kinds of chemistry II textbooks of the 2015 revised curriculum in this study. The problems of the textbook were divided into the problems of definitions and the representations of the logical thinking. As a result of the study, the lack of the concept of chemical equilibrium had a problem with the representation of reversible reactions in the definition of the Brønsted-Lowry model in the Chemistry I textbooks of 2009 revised curriculum, it also appeared to persist in Chemistry I textbooks of 2015 revised curriculum which contains the concept of chemical equilibrium. The representations of logical thinking were related to particle kinds of conservation logic, combinational logic, particle number conservation logic, and proportion logic. There were few problems related to representation of logical thinking in Chemistry I textbook in 2009 revision curriculum, but more problems of representations related to logics are presented in Chemistry I textbooks in 2015 revision curriculum. Therefore, as the curriculum is revised, the representations of chemistry textbooks related to acid and base models need to be changed in a way that can help students' understanding.

  • This study analyzed the research papers published in three (2 domestic and 1 foreign) journals, in order to understand the recent trend of chemistry education research. We selected Journal of the Korean Chemical Society (JKCS) and Journal of the Korean Association for Science Education (JKASE) as the domestic journals, and Journal of Chemical Education (JCE) as a foreign journal. The papers published from 2000 to 2009 were analyzed. As the result, the chemistry education research theme focused on 'teaching method and education technology', 'learner's characteristics', and 'chemical concept and experiment' in the order of frequency. The research on 'curriculum and textbooks' was performed often in JKCS reflecting Korean social environment. The most researched chemistry education goal was the 'conceptual understanding/change' followed by 'achievement/grade' in JCE and 'experiment/inquiry skill' in JKCS, and 'attitude/interest/motivation' in JKASE. The research subjects were focused to 'middle or high school students' in JKCS, in contrast to the 'university students' in JCE. More concern to the higher education is required in the domestic research. The most frequently used research method was 'survey/ examination' followed by 'experimental research' in JCE and JKASE and 'data/material analysis' in JKCS. We discussed the implication on future chemistry education research.
