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.

The goal of this study is to explore ways to restructure Convergence Elective Courses in science in preparation for the high school credit system, ahead of the 2022 revised science curriculum. This study started from the problem that the 2015 revised science curriculum has not guaranteed science subject choice for students with non-science/engineering career aptitudes. To this end, a survey was conducted by randomly sampling high schools across the country. A total of 1,738 students responded to the questionnaire of 3 science elective courses such as Science History, Life & Science, Convergence Science. In addition, in-depth interviews with 12 science teachers were conducted to examine the field operation of these three courses, which will be classified and revised as Convergence Elective subjects in the 2022 revised curriculum. According to the results of the study, high school students perceive these three courses as science literacy courses, and find these difficult to learn due to lack of personal interest, and difficulties in content itself. The reason students choose these three courses is mainly because they have aptitude for science, or these courses have connection with their desired career path. Teachers explained that students mainly choose Life & Science, and both teachers and students avoid Science History because the course content is difficult. Based on the research results, we suggested ways to restructure Convergence Electives for the 2022 revised curriculum including developing convergence electives composed of interdisciplinary convergence core concepts with high content accessibility, developing convergence electives with core concepts related to AI or advanced science, developing module-based courses, and supporting professional development of teachers who will teach interdisciplinary convergence electives.

Objective: The goal of this study is to develop an instrument for measuring the quality of teacher support for children's play (age 3-5) based on the Play Practice Resources for Teachers presented in the 2019 revised Nuri Curriculum. Methods: The subjects of this study were 333 early childhood educators. Exploratory and confirmatory factor analysis, as well as correlation analysis were all performed to confirm construct validity and concurrent validity. The reliability of each factor was verified using Cronbach's alpha. Results: The Preschool Teacher Play Support Scale (PTPSS) was finalized with 25 items, which included the following four sub-factors: interaction, play materials, play space, and play safety. The concurrent validity was also confirmed through significant correlations between the existing measures such as the Teacher Self-Efficacy Scale, the Teaching Efficacy Scale for Play, and the Teacher-Toddler Interaction Scale. The reliability of each factor was also desirable. Conclusion/Implications: The PTPSS was verified as a sound measure quantifying the play support behavior of teachers who respect the autonomy and initiative of young children which is being pursued by the 2019 revised Nuri Curriculum.

The purpose of this study was to analysis the home economics education curriculum from the first national curriculum to the 2015 revised curriculum using text mining techniques used in big data analysis. The subjects of the analysis were 10 curriculum texts from the first national curriculum to the 2015 revised curriculum via the National Curriculum Information Center. The major findings of this study were as follows; First, the number of data from the 4th curriculum to the 2015 revised curriculum gradually increased. Second, as a result of extracting core concept of the curriculum, there were core concept words that were changed and maintained according to the curriculum. 'Life' and 'home' were core concepts that persisted regardless of changes in the curriculum, after the 2007 revised curriculum, 'problem', 'ability', 'solution' and 'practice' were emphasized. Third, through core concept network analysis for each curriculum, the relationship between core concepts is represented by nodes and lines in each home economics curriculum. As a result, it was confirmed that the core concepts emphasized by the times are strongly connected with 'life' and 'home'. Based on these results, this study is meaningful in that it provides basic data to form the identity and the existing direction of home economics education.

The purpose of this study is to assist understanding the integrated subjects and to obtain implications required on the actual operation of curriculum by analyzing content elements and basic inquiry activities in the revised "wise lift" curriculum 2007. The result of this study is as follows. First, the formation of elements in contents of "wise life" deals with the passage of time based on changing seasons, myself and family in the 1st grade and the concept of space based on home and a village in the 2nd grade. Six main subjects and twelve activity subjects are presented per each grade. Second, number of activity subjects and content elements are reduced as compared with 7th curriculum so that the responsibility of operating classes based on activities is reduced and the purpose of rationalizing contents is somewhat fulfilled. Third, eliminating a relevant domains decisively when presenting the activity subjects assures the identification and purpose as the integrated subject focused on inquiry activities. Fourth, the result of analyzing the course-relevance on content elements shows that the allotment per each domain and course is less considered but the relevance of social studies is higher regardless of non-course characteristics as the integrated subject. Fifth, according to the component ratio of basic inquiry activities, 'Observing' and 'Debating' were presented as the most essential activities, and 'Measuring' and 'Making' were relatively low. By considering characteristics of course requiring balanced and various experiences of inquiry activities, additional discussions are required on appropriateness of the component ratio. Sixth, 'Observing' was increased and 'Debating' and 'Making' were decreased on the main activities in this revised curriculum as compared with 7th curriculum.

The purpose of this study is to examine implications of pre-service science teacher training by analyzing science field integration and connection between learning content presented in 'Integrated Science' for high school students based on the 2015 revised science curriculum, and in pre-service science learning materials (textbooks) of the college of education. For this study, the 2015 revised 'Integrated Science' curriculum and 11 types of pre-service science teachers' learning materials related to physics, chemistry, biological science, and earth science were selected. The results were as follows. Most of the learning content presented in the 2015 revised 'Integrated Science' curriculum had integrated two or more science fields. Also, almost all learning content presented in the 2015 revised 'Integrated Science' curriculum were included in pre-service science teachers' education content, with educational content for chemistry introduced at the highest rate. The textbooks for pre-service science teachers had the most learning contents of 'Energy and Environment' domain of 'Integrated Science' for high school students. Accordingly, these results suggest that 'integrated science materials' should be developed for proper the curriculum implementation. Also, training courses for science teachers responsible for 'Integrated Science' are required. Furthermore, a revised curriculum for the college of education and a method to link with certification examinations for secondary school teachers are needed.

The aim of this study was to investigate differences in the achievement standards from the 2015 to the 2022 revised national science curriculum and to present the implications for science teaching under the revised curriculum. Achievement standards relevant to primary science education were therefore extracted from the national curriculum documents; conceptual domains in the two curricula were analyzed for differences; various kinds of centrality were computed; and the Louvain algorithm was used to identify clusters. These methods revealed that, in the revised compared with the preceding curriculum, the total number of nodes and links had increased, while the number of achievement standards had decreased by 10 percent. In the revised curriculum, keywords relevant to procedural skills and behavior received more emphasis and were connected to collaborative learning and digital literacy. Observation, survey, and explanation remained important, but varied in application across the fields of science. Clustering revealed that the number of categories in each field of science remained mostly unchanged in the revised compared with the previous curriculum, but that each category highlighted different skills or behaviors. Based on those findings, some implications for science instruction in the classroom are discussed.

This study elucidates the achievement standards statements of the 2022 revised elementary school science curriculum to identify specific achievement standards for the upcoming curriculum. Therefore, the researcher analyzed the statements of the overall elementary school achievement standards based on Bloom's taxonomy of new educational objectives. The results are as follows. First, the achievement standards statements are biased toward certain knowledge and cognitive process dimensions; this aspect is not consistent with the goals of the 2022 revised curriculum and the teaching and learning directions of the science department. Thus, achievement standards that enable various types of activities and inquiry learning should be developed. Second, a need emerges for the hierarchization of knowledge and cognitive levels by grade level. The proportions of low levels of knowledge and cognitive process dimensions increased in the upper grades, such that a systematic hierarchy should be considered. Third, the need to diversify the use of the descriptors of achievement standards is also identified. Although the tendency to rely on specific descriptors decreased during the previous curriculum, approx imately half of the descriptors were only used once or twice. Therefore, balancing the use of various descriptors is necessary. To ensure that the results are reflected in the achievement standards for elementary school science textbooks under the revised science curriculum for elementary schools in 2022, a discussion is required on the design of achievement standards statements. As a follow-up study, the researcher proposes a comparative analysis of the achievement standards of science curricula for middle and high schools to explore the wording of achievement standards appropriate for elementary school science education considering its nature, goals, and contents and to analyze the hierarchy and continuity of the entire science curriculum.

The revised informatics is to be compulsory for middle school students from 2018 according to 2015 revised curriculum. The concept of abstraction in informatics curriculum has common features and differences compared with general abstraction, however there is a mix of concepts in the current informatics textbook. The abstraction of computational thinking needs to connect with automation, so it is difficult to teach correct concept of abstraction with these textbooks. Therefore, this research conducted to investigate several informatics textbooks that were developed by the revised curriculum and to analyze the concept and examples of abstraction. As a result, some textbooks have that there is a mix of concepts about general abstraction and no connection with automation. This research suggests clarified abstraction and educational examples for cultivating computational thinking to improve this situation. This result will be basic recourse for the reconstruction of abstraction lesson to improving computational thinking.

The purpose of this study is to find historical paradigm shift of the environmental subject in Korean school curriculum. For the purpose, two research questions guided this study. First, we would like to find out the changes in environmental education curriculum by interpreting the Korean national curriculum. Second, we want to know about the paradigm shift of environment education in Korea. In this study, curriculum documents, teachers' guide books, textbooks, and other educational materials were used for literature review. The results are as follows: First, Robottom and Hart's frame of three paradigms in environmental education research, positivism, interpretivism and social criticism, was suitable in interpreting curriculum. Second, the curriculum of environment subject has substantially changed from 6th to 2007 revised curriculum. Third, while the 6th curriculum was strongly affected by the positivism and education 'about' the environment, the 7th curriculum had been influenced by the interpretivism and education 'in/through' the environment, and the 2007 revised curriculum is under the influence of the education 'for' the environment and social critical paradigm.
