This study analyzed the difficulty level of class on the seasonal change unit for 84 students at a university of education. The conclusions of this study are as follows. First, if we first present the four topics that make up the seasonal changes in elementary science, the subjects that have the greatest difficulty in teaching for prospective elementary school teachers are 'Why do seasonal changes occur?' (Teaching difficulty level 4.05), 'The sun changes depending on the season' What is the difference between the southern altitude and the length of day and night?' (difficulty level of class, 3.12), 'What is the relationship between the altitude of the sun, length of shadow, and temperature during the day?' (difficulty level of class, 2.85), 'How does the temperature change depending on the season?' (class difficulty level 2.80). As a result, in the elementary science season change unit, the class on the four topics 'Why do seasons change?', which is classified as a class topic that requires the concept of spatial perception, showed a higher level of class difficulty than other units. Second, in the seasonal change unit, various factors of class difficulty appeared depending on the class topic. When pre-service elementary school teachers look at the factors that make class difficult when teaching a lesson on seasonal changes in order of frequency, 42 (50%) said 'Experimental instruction for comparing the altitude of solar masculine according to the tilt of the axis of rotation', followed by 'Solar masculine'. 38 people (45%) answered 'Difficulty in explaining mid-high altitude and the length of day and night', 27 people (32%) answered 'Difficulty in explaining the concept of mid-high altitude', and 24 people (32%) answered 'Difficulty in explaining seasonal changes in the sun's position.' 29%), 20 people (24%) said 'Explain the reasonable reason why the height of the light should be adjusted when measuring the solar altitude', and 16 people (19%) said 'It is difficult to explain the reason for the discrepancy between the solar altitude and the maximum temperature'. ), 'difficulties in measuring sand (ground) temperature' were mentioned by 12 people (14%). Third, when analyzing the factors of class difficulty, there were more curriculum factors than teacher factors. In this context, the exploratory activities on 'Why do seasonal changes occur?', the fourth topic of the seasonal change unit in which elementary school pre-service teachers showed the greatest difficulty in teaching, need improvement in terms of the curriculum.

Philosophical and social backgrounds and inquiring into new direction of Practical Arts and Home Economics Education is done through this paper. The overall review of the related documents, records, books has been done, and research findings are presented as follows; Thought(Educational theory and Philosophy) for Korean Practical Arts Education is based on Learning to Labor, Practical Science and Pragmatism. Korean curriculum for Home Economics were originated in Confucianism background, which stressed the importance of different gender roles for men and women. However, Korean Home Economics based on Home Economics Subject Matter has been developed without philosophical base unlike that of American Pragmatism and Critical Theory. Therefore, scientific recognition in a section of value recognition was separated and developed so far. Thus, we could not answer to social missions about keeping values of life corresponding with changing environment I also observed the analysis of revision curriculum of the mentioned subject, and the changes of concepts of Work and Prasix, necessity of Home Economics Education for fixing about a basic life education and a basic life skill, and reinforcement of the function in Home. And then, new directions is proposed that the role of Home Economics Education in school be reinforced for the upcoming low birth rate and the aging society(high proportion of the aged people). Because Characters on correct values of children and youths might be nurtured in home foremost.
This study aims to suggest implications on develop and operate NCS curriculum by analyzing of differences in perception and educational needs of university students, graduates, human resource managers(HR managers) on NCS basic job skill. The respondents of survey are composed of 533 university students in K university, 730 graduates and 106 HR managers. The major findings are as follows: first, the results showed that the importances of all competencies recognized by HR managers was higher than those of university students and graduates. And graduates perceived their level of competencies as higher than those of university students. Second, the needs for self-development skill, technical skill, and problem-solving skill was the highest within the students and graduates, meanwhile, the needs for the mathematical skill, resource management skill, and the organization understanding skill were low. In contrast, the results of this study showed that the HR managers has the high needs for self-development skill, communication skill and problem-solving skill. Also, HR managers has the low needs for mathematical skill, resource management skill, information skill, technical skill, organizational understanding skill, and job ethics. Based on the above results, we proposed the necessity to develop and apply the NCS curriculum considering the education needs recognized by current students, graduates, and HR managers.

This study was performed the analysis of four kinds of common science textbooks based on the 6th curriculum. Particularly, inquiry activity part was analyzed by the three dimension framework which consists of inquiry content dimension, inquiry process dimension and inquiry context dimension. In the analysis of the inquiry content dimension of inquiry activities, the contents revised by 6th curriculum of common science textbook was accomplished through various inquiry activities. The number of inquiry activity in four textbooks was similar as about 16. The For the analysis of inquiry process dimension, 'interpreting data and formulating generalizations' category (39.1%) was most emphasized and the categories of 'observation and measuring'(30.8%), and 'building, testing and revising the theoretical model' (16.5 %), 'seeing a problem and seeking ways to solve it' (13.5%) follow in order. As for the analysis of the inquiry context dimension, the proportion of STS related contents in inquiry activities was only 18%. So, we propose that STS related contents would increase the proportion for the following textbook.
Purpose: This study was undertaken to provide the framework for development of a genetic counseling training program, and an accreditation and certification process suitable for non-M.D. genetic counselors in Korea. Materials and Methods: Global standards of genetic counseling curriculums, training program accreditation (TPA), and the certification process for genetic counselors (CPGC) in the U.S.A and Japan were reviewed, and a questionnaire survey was performed to elicit opinions among health-care providers including physicians, nurses, technicians, researchers, and educators. In addition, input from professional communities, including the Korean Society of Medical Genetics (KSMG) and Institute for Genetic Testing Evaluation, was sought in formulating the framework of this study. Results: Comparison of U.S.A. and Japan educational systems showed similarities in curriculum, accreditation, and certification programs. Analysis of 117 respondents opinions showed a high level of agreement in the area of global standards; 88% indicated that KSMG should be in charge of TPA and CPGC, while 77% favored a certification exam composed of both written exam and interview components. Conclusion: Based upon this study we propose that the KSMG should be in charge of providing the TPA and CPGC for non-MD genetic counselors. Requirements for the entrance to a Master's degree genetic counseling program should be open to successful four year undergraduate students in all areas, provided the candidates demonstrate the abilities to master the graduate level of study in human genetics, clinical genetics, statistics, psychology, and other required subjects. Eligibility for certification should include qualified candidates of genetic counseling with no formally approved education, but a sufficient amount of clinical experience, in addition to accredited program graduates. Certification examinations should be carried out every two years and the certification should be good for five years, as is the case in Japan.
The 2009 revised curriculum emphasizes science writing as a way to foster scientific thinking, creative thinking and communicative abilities. This research attempted to find out the aspects of science writing in science textbooks by analyzing seven versions of the 2009 revised science textbooks. The results of the analysis are as follows. First, it was found that the proportion of science writing pages is small and the amount of science writing differs a lot depending on the kind of textbook. Also, science writing is generally located in the wrap-up part of each unit, and the amount and the number of science writing vary substantially from unit to unit depending on the textbook. Second, it was found that 'scientific knowledge-explanation' statements have the largest proportion and 'STS-assertion' statements have the second largest proportion in terms of topics and styles of science writing in science textbooks. Some 'scientific knowledge-explanation' statements are not appropriate to foster scientific ability because they evaluate reading comprehension of the suggested passage as nonliterary writing, not the writing itself as a method to learn science. Third, it was found that there are many predicates that do not indicate a clear purpose of the science writing contained in science textbooks.

This study analyzed the trends in home economics education research using the language network analysis method, focusing on papers published in the KCI list for 20 years from 2000 to 2019. A total of 501 home economics education papers analyzed through word cloud, centrality analysis, and topic modeling using NetMiner 4.4, and the results are as follows. First, the number of papers in home economics education published in the KCI listing increased gradually to 186 in the 2000s and 315 in the 2010s. The academic journals in which home economics education papers were published have been diversified to 16 in the 2000s and 22 in the 2010s. 60% of all papers were published in the 'Journal of Korean Home Economics Education Association', and since 2018, the number of papers published in the 'Journal of Learner-Centered Curriculum and Instruction' has increased dramatically. Second, in the 2000s and 2010s, home economics education studies published in KCI were categorized into home economics education content analysis, home economics educational program development & application, curriculum analysis, perception survey & direction exploration. In the 2000s, 'Home Economics Teacher' appeared as the main keyword, and a lot of perception survey & direction exploration were conducted. Relatively, the influence of 'development' increased in the 2010s, and many studies were conducted to analyze home economics education contents and develop and apply home economics programs. This study has significance in that it analyzed the research trend of HEE by expanding the analysis target and analysis period of the existing studies.

Size/scale is a central idea in the science curriculum, providing explanations for various phenomena. However, few studies have been conducted to explore student understanding of this concept and to suggest instructional approaches in scientific contexts. In contrast, there have been more studies in mathematics, regarding the use of number lines to relate the nature of numbers to operation and representation of magnitude. In order to better understand variations in student conceptions of size/scale in scientific contexts and explain learning difficulties including alternative conceptions, this study suggests an approach that links mathematics with the analysis of student conceptions of size/scale, i.e. the analysis of mathematical structure and reasoning for a number line. In addition, data ranging from high school to college students facilitate the interpretation of conceptual complexity in terms of mathematical development of a number line. In this sense, findings from this study better explain the following by mathematical reasoning: (1) varied student conceptions, (2) key aspects of each conception, and (3) potential cognitive dimensions interpreting the size/scale concepts. Results of this study help us to understand the troublesomeness of learning size/scale and provide a direction for developing curriculum and instruction for better understanding.
In this study, we analyzed the causes of decrease in the number of students taking Chemistry ? in the College Scholastics Ability Test (CSAT) by analyzing the adequacy of the Chemistry I question in the CSAT and the recognition survey of students and teachers about the Chemistry I choice. We analyzed some questions in Chemistry I of the CSAT from the year 2014 to 2016. The questions were analyzed to determine whether they were appropriate to the curriculum content, achievement standard, and achievement level. The target of the survey for perception was 452 senior high school students and 68 science teachers. The result of the study showed that the questions in Chemistry I are somewhat difficult compared to the depth and achievement level required by the curriculum, and it also requires mathematical thinking ability. Students recognized the mathematical thinking and complex mathematical skills are needed to solve problems in Chemistry I. Teachers also thought that the choice of Chemistry I is unfavorable in aspect of meeting the minimum academic ability standard, and accordingly, they did not actively recommend students to take Chemistry I. Moreover, most of the teachers recognized that it is necessary to improve the direction of writing questions for Chemistry I. Therefore, setting questions that can be solved using chemical knowledge, not mathematical ability need to be addressed.

The purpose of this study is to investigate the influences of Science Core schools on students' positive experiences about science (PES) through in-depth interviews with teachers in charge of science core schools. In-depth interviews with teachers were conducted to explore the factors that led to the effectiveness of science core schools in improving the student's PES in light of operational characteristics of science core schools as leading schools, characteristic factors of science core schools on students PES, and improvement plans and requirements of science core schools as leading schools, as well as implications for general high schools. In the case of science core schools, the teacher's enthusiasm for science teaching encouraged students' participation in science classes, promoted students' interest in science other than science-core classes, improved students' inquiry and research skills, increased students' competencies such as communications and collaboration by improving science instructions, and affected career search and exploration based on interests in science experiences. Based on the results, ways to spread the characteristics of science core schools to general schools' curriculum implementation are suggested including providing opportunities to experience the value of science study, to experience science and engineering careers through senior students, to participate in team projects and self-regulated science inquires, and so on.
