Changes in education or curriculum are based on the needs of the times and needs to address changes in knowledge. The purpose of this study was to provide implications regarding the general guidelines of the national curriculum by analyzing changes made in the high school informatics curriculum in which both needs are inherent. The study involved an analysis of the general guidelines to the national curriculum that involved the revision years 2007 and 2009, the composition of the 2015 revised curriculum, change in the status of the informatics curriculum, and the size of the informatics subject. As a result of the analysis it was found that several improvements are necessary, namely (1) the units need to be better clarified, (2) career electives need to be more appropriately composed, and (3) definitions of terms need to be better clarified. The significance of this study lies in the fact that it considered the viewpoint of software education emphasized in various countries around the world, and the general guidelines to the national curriculum were examined to learn what kind of organization and operation should be proposed for high school informatics.

Objectives: The purpose of the study was to examined the demand for the change in Korean dental hygiene curriculum. This study compared the dental hygiene curriculum of domestic and overseas university and tired to provide the basic data for the development of standard curriculum that meets the education policy changes. Methods: Data were obtained from a cross-sectional survey of 1,192 participants including dental hygiene professors, dental hygienists and students. Data were collected by mail, telephone call from the professors and research assistants, email, and direct visit from June 10 to August 10, 2013. The questionnaire consisted of 4 questions of general characteristics of the subjects and 13 questions of dental hygiene curriculum. Results: The professors answered the development of integrated dental hygiene curriculum as the first priority(48.9%) and dental hygienists(51.6%) and students(42.6%) chose the development of new dental hygiene curriculum(p<0.001). In the analysis of validity of dental hygiene curriculum, the professors gave 3.29 to the validity of evaluation for basic job performance, and the clinical dental hygienists and the students gave 3.05 and 3.26 points, respectively(p<0.001). In relation to the necessity of the change of the dental hygiene curriculums, the professors gave 4.17 points which implied that curriculum change is the most important and necessary thing to do. The clinical dental hygienists and the students gave 3.90 and 3.47 points, respectively(p<0.001). Conclusions: The above-mentioned findings suggest that the revision of the current Korean dental hygiene curriculums is required. Therefore organizations related to dental hygiene including professor association and Korean Dental Hygienists Association should carefully rebuild the curriculum to improve the competency of dental hygienists. They should take the initiative in the development of a standardized curriculum.

Teacher reeducation is required to be comfortable with the 'Integrated science' subject as introduced in the 2015 revised curriculum. In this research, we designed in-service teacher training programs according to the types of secondary school science teacher's certificates, and developed ways to improve in-service science teachers' competencies. Through Delphi surveys with 22 science education experts, we investigated the features of the 2015 revised 'Integrated science' curriculum in light of its characteristics, purposes, contents system, contents, and so on, and explored teachers' competencies to teach the subject. Based on the analysis of the features of each type of secondary school science teachers' certification and required teacher competencies for teaching 'Integrated science', we developed three types of teacher training programs: in-service training courses for understanding the 2015 revised 'Integrated science' (Type A), in-service training courses for 'Integrated science' (Type B), and in-service teacher training certificate program for 'Integrated science' (Type C). For each teacher training program, we suggested the target of the training program in light of teacher certificates, operation systems, and ways to organize the program. In addition, we also suggested ways to improve 'Integrated science' teacher education programs for pre-service as well as in-service teachers, and examined ways to improve educational requirements for qualification in 'Integrated science' teaching based on the opinions of experts. Discussed in the conclusion are ways to design in-service teacher training programs for 'Integrated science' teaching and ways to improve 'Integrated science' teacher training.

The purpose of this study is to analyze application status about the process-centered assessment in elementary school science classes. For this purpose, a survey was conducted with 133 teachers and 2,089 students in elementary schools, and in-depth interviews with eight teachers were conducted. Elementary school teachers had a positive attitude toward the adoption of the process-centered assessment of 2015 revised science curriculum. After applying 2015 revised science curriculum, teachers used more performance assessments and less traditional ones in science classes. Elementary school students recognized that they receive feedbacks from their teachers more often with the implementation of the 2015 revised science curriculum. Through in-depth interviews, it was possible to confirm the difficulty of applying the process-centered assessment of elementary school teachers, such as lack of understanding of process-centered assessment and lack of time for its application. Based on the results of the study, the necessity for improving teacher understanding of process-centered assessment and the need to disseminate process-centered assessment materials are suggested.

The goal of this study is to investigate the features of Korean eighth graders' achievement and its trend in Chemistry in TIMSS 2011 and TIMSS 2015, and to explore its implications for Korean science curriculum and in teaching science. With three science educators and six science teachers, we analyzed the characteristics of Korean eighth graders' achievement in Chemistry by test-curriculum matching analysis. According to the trend analysis of science topics with released items for Chemistry in TIMSS 2015, Korean students' percentage for correct answers has dropped in topics such as regularities in chemical reactions, oxidation-reduction, etc. since these topics are covered after the ninth grade in the 2009 revised curriculum. For science cognitive domains, Korean students showed weaknesses in 'applying' domain in TIMSS 2015. Based on the results, we suggested implications for improvement in middle school chemistry curriculum and how to improve science teaching and learning for students' better science competencies and real-world application of science knowledge.

This study aims to propose the future direction of research of the Nuri-Curriculum, a national level curriculum, analyzing the subjects, the research methods, and the contents of Nuri-Curriculum studies, and current research trends. For these purposes, 102 Nuri-Curriculum articles in major child care-related journals from 2012-2015 are reviewed. PASW 18.0 program was used to calculate frequency and percentage rate. The major findings are as follows. First, a considerable amount of research has been carried out despite a relatively short implementation period. Second, many research topics dealt with include curriculum-related material. Third, 74.5 percent of the articles used quantitative methods, and content-analysis was the most widely used method among them. On the contrary, there was relatively less research which used the experimental method applying the curriculum to real practice, observational or qualitative method. Fourth, most of the research contents focus on the direction of making of the curriculum. Therefore, this paper proposes the necessity of supplementary research including its application to real practice as the research approaches on the Nuri-Curriculum performed so far have been limited.

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.

In recent years, astronomy has been snowballing: including Higgs particle discovery, black hole imaging, extraterrestrial exploration, and deep space observation. Students are also largely interested in astronomy. The purpose of this study is to discover what needs to be improved in the current astronomy curriculum in light of recent scientists' researches and discoveries. We collected keywords from all papers published from 2011 to 2020 in four selected journals-ApJ, ApJL, A&A, and MNRAS- by R package to examine research trends. The curriculum contents were extracted by synthesizing the in-service teachers' coding results in the 2015 revised curriculum document of six subjects (Science, Integrated Science, Earth Science I, Earth Science II, Physics II, Convergence Science). The research results are as follows: first, keywords that appear steadily in astronomy are 'galaxies: formation, galaxy: active, star: formation, accretion, method: numerical.' Second, astronomy curriculum includes all areas except the 'High Energy Astrophysical Phenomena' area within the common science curriculum learned by all students. Third, it is necessary to review the placement of content elements by subject and grade and to consider introducing new concepts based on astronomy research keywords. This is an exploratory study to compare curriculum and the field of scientific research that forms the basis of the subject. We expect to provide implications for a future revision of the astronomy curriculum as a primary ground investigation.

New Zealand had reformed their national curriculum with competence and are applying the revised curriculum. As the 2015 revised national curriculum is clothed with competency-based curriculum, New Zealand may have important implications for the study of the Korean revised curriculum. In this study, we examine characteristics of the education system and the national curriculum in New Zealand. In addition, we analyze the standards into the New Zealand national curriculum in terms of 'curriculum connectivity' that is one of important curriculum criteria for improving the quality of education. For this, we look an overview of the relation between the New Zealand curriculum and NCEA, which is the core of the student-centered education system in New Zealand, and analyze the correspondence between the New Zealand curriculum and the Korean curriculum. And we establish analysis framework of curriculum connectivity based on these comparison analysis contents, and analyze Korean mathematics standards with corresponding levels from among the New Zealand mathematics curriculum. According to the results of this study, the New Zealand curriculum includes the most of standards which Korean high school students who want to enter university of natural sciences of engineering need to require. In addition, the New Zealand curriculum highlights statistical research activities for developing problem-solving ability in real life. From perspective of curriculum connectivity, 'in-depth contents' adding on to repeating mathematical concepts or contents are included in the New Zealand curriculum.

In this study, we investigated how 'Scientific Inquiry Experiment,' a newly introduced subject under the 2015 revised curriculum, was implemented to identify the difficulties that science teachers face in the process of teaching the subject and to explore how to support them through online survey and interview methods. A questionnaire of the survey, which consisted of environmental factors of class, preparation and execution of class, teacher self-evaluation of class, and direction for the subject, was developed, and the online survey was requested with a response from one teacher per school from 1674 high schools nationwide. We analyzed the results from 814 teachers who answered all required questions, and we also conducted interviews and online advisory discussions to ensure the validity of our analysis. In the results of the study, teachers complained of lack of time for preparation and execution of the subject, and they demanded laboratory assistants and quality teaching materials. In addition, in order to achieve the goal of the subject, they agreed the necessity of using the 'block scheduling' though they also agreed the difficulties of its implementation. Meanwhile, the alteration of guidelines for evaluation, which was changed from 9-grade system to 3-grade system, was positively recognized by teachers. As a result of this change, the percentage of performance assessment increased in 2019 compared to 2018, but there were no significant changes in the number of 'hands-on activity.' Finally, we proposed ways to support 'scientific inquiry experiment'.
