The purpose of this study was to develop curriculum of the elementary, and secondary school home economics that integrates three systems of action and to prepare a plan for convergence education in home economics curriculum. To achieve this goal, the characteristics of elementary, secondary school dietary curriculum integrating three systems of action, the focus of development, core competencies, and goals were derived through the review of literature. In this study, we set up perennial and sub-practical problems and selected content elements. The contents system of the developed curriculum was modified and supplemented by examining the validity of experts, and the achievement standard of the middle school home economics dietary education curriculum was developed by integrating the three systems of action. The content system of the elementary, and secondary school home economics curriculum that integrated the three systems of action is centered on practical problems, and the perennial problem is 'What should we do to practice healthy dietary life?' There are five areas of this curriculum: 'health and diet', 'food planning', 'food purchase and management', 'cooking', and 'meal', and the scope of curriculum is repeatedly expanded to 'personal and family', and 'social'. The practical problems in the five areas are composed of 10 practical problems in the two dimensions (personal & family, and society), and the practical problems and contents elements are spiralled by applying the principle of integration. The contents of this curriculum were compared with the achievement standards and learning elements of the dietary life in the 2015 elementary school practical arts, middle and high school 'technology & home economics', and the 'home economics science' curriculum. The results showed that the developed curriculum encompassed additional content beyond all the content already included in the 2015 revised curriculum.

The Ministry of Education announced plans to introduce SW education to elementary and secondary schools in the 2015 curriculum. However, if we examine major foreign countries where SW education strongly implemented it is found that they stress not only coding education but also real life SW education. Especially they emphasized convergence with other different fields. Therefore, it can be concluded SW education in Korea should be differentiated based on levels of students. For the common basic curriculum, it is needed basic concepts and thinking skills of SW development, but for the enriched curriculum, it should be emphasized SW development education that can be applied to real life experiences and other difference fields as well. Therefore, it is necessary to plan SW intensive education to develop programs for the enriched program. In this study, I explored how virtual reality programming education can be applied to the level of elementary and secondary school students as an enrichment program.

The purpose of this research was to survey and compare the status of science preference of elementary school students with that of middle school students. Preference for science was defined theoretically. According to theoretical model, a questionnaire was developed with piloting and consisted of three parts. First part was for background information, second part, for measurement of science preference and third for measurement of the relevant factors of science preference. The questionnaire was modified for primary school students. In July 2002, the questionnaire was administered to one class per grade of randomly selected 8 elementary and 8 middle schools all over the country and analyzed result of collected 696 elementary school students and 819 middle school students. Middle school students' science preference was low compared with elementary school students, especially in 'emotional response and 'valuational comprehension'. The preference for science became lower especially from 4th to 5th grade and from 8th to 9th grade. The differences of mean science preference were significant by gender. perception of science achievement. and future career choice. The average of science preference relevant factors of middle school students also became lower than elementary students, especially in 'educational factor'. Multiple regression analysis on the science preference showed that important factors were personal ability, the personal traits, rewards in school science and contents of school science, slightly different in elementary and secondary school. The way to promote students' preference for science was suggested on the analysis result.

This study aims to discuss the basic foundations to set levels and language skills for developing a Korean Proficiency Test for young and adolescent learners. Recently, there has been an increase in demand regarding young and adolescent learners from multicultural and overseas backgrounds. However, the current Korean Proficiency Test lacks the appropriate means to determine the Korean proficiency of young and adolescent learners with general purposes of language learning. Therefore, there is an urgent need for developing a specialized and new form of language assessment for young and adolescent learners who are exposed to a foreign language or a second language learning environment. The study examines and analyzes cases of foreign language examinations for young & adolescent learners; furthermore, the objectives and target were set based on the results of a needs analysis and in-depth interviews conducted among teachers and education officials in overseas Korean Hangeul Schools, international schools, elementary and secondary schools. Finally, the levels and language skills appropriate for the objectives of a proficiency test and target learners have been suggested.

The purpose of this study is to investigate teachers' perception of core competencies and affective aspects in mathematics. For this purpose, a nationwide survey was conducted. The survey questionnaire consists of three core competencies including problem solving, reasoning and communication, and two affective aspects including good human nature and attitudes. The survey results were further analyzed based on school level, teaching experience, location of schools, and types of high schools. As a result, four findings were identified. First, elementary school teachers tend to put more emphasis on core competencies and affective aspects than secondary school teachers do. Second, in elementary school level, longer teaching experience is correlated with more positive perception of core competencies and affective aspects. However, there was an opposite tendency in secondary school level. Third, teachers working at schools in metropolitan cities tend to emphasize core competencies and affective aspects more than those at schools located in mid-sized cities and rural areas. Fourth, the school types in high school didn't seem to affect the teachers' perception on core competencies and affective aspects.

The purpose of this study was to examine the status and science teachers' perceptions of classes for those gifted in science in elementary school. For this purpose, a number of questions were posed to teachers : 27-item-questionnaires were given to 38 teachers of students gifted in science in elementary schools located in Incheon province. The results of this study were as follows : 1. most elementary teachers were in charge of classes containing students gifted in science, but this was the case with only a few secondary teachers. Therefore, it appears to be more necessary to educate elementary teachers who majored in science content and gifted education. 2. In addition, most teachers had positive perceptions of the needs, attitudes and environments needed for gifted education. Most of them attended 60-hour training programs on gifted education. They thought that it was helpful in understanding the characteristics of gifted students, but they wanted to learn more about actual pedagogical methods through such programs. 3. The teaching methods used in classes for those gifted in science were mainly experimental activities, but there were few opportunities for creative problem solving and project learning. This may be due to limited class time of about one hour every two weeks in this class. 4. When the materials used in class were first developed, they mainly used materials made by the city board of education and selected the theme of interest by themselves. Therefore, there may be problems of duplication of materials or systems regarding the science contents for one year. 5. Furthermore, the themes of the materials used were mostly related in terms of the contents of textbooks than more generally. When planning and managing the classes for those gifted in science, the above points should be considered in order to improve the education of those students gifted in science.

Recently, parents and teachers consider physical education as a minor subject for students in elementary and secondary schools. Physical education performance has become increasingly significant as parents and schools pay more attention to physical schooling. The sports mining with distribution analysis model considers different factors, including the games, comments, conversations, and connection made on numerous sports interests. Using different machine learning/deep learning approach, children's athletic and academic interests can be tracked over the course of their academic lives. There have been a number of studies that have focused on predicting the success of students in higher education. Sports interest prediction research at the secondary level is uncommon, but the secondary level is often used as a benchmark to describe students' educational development at higher levels. An Automated Student Interest Prediction on Sports Mining using DL Based Bi-directional Long Short-Term Memory model (BiLSTM) is presented in this article. Pre-processing of data, interest classification, and parameter tweaking are all the essential operations of the proposed model. Initially, data augmentation is used to expand the dataset's size. Secondly, a BiLSTM model is used to predict and classify user interests. Adagrad optimizer is employed for hyperparameter optimization. In order to test the model's performance, a dataset is used and the results are analysed using precision, recall, accuracy and F-measure. The proposed model achieved 95% accuracy on 400^th instances, where the existing techniques achieved 93.20% accuracy for the same. The proposed model achieved 95% of accuracy and precision for 60%-40% data, where the existing models achieved 93% for accuracy and precision.
