The purpose of this study was to identify heuristically how abduction was used in a context of solving an earth-environmental problem. Thirty two groups of participants with different institutional backgrounds, i,e., inservice earth science teachers, preservice science teachers, and high school students, solved an open-ended earth-environmental problem and produced group texts in which their ways of solving the problem were written, The inferential processes in the texts were rearranged according to the syllogistic form of abduction and then analyzed iteratively so as to find thinking strategies used in the abductive reasoning. The result showed that abduction was employed in the process of solving the earth-environmental problem and that several thinking strategies were used for inferring rules from which abductive conclusions were drawn. The strategies found included data reconstruction, chained abduction, adapting novel information, model construction and manipulation, causal combination, elimination, case-based analogy, and existential strategy. It was suggested that abductive problems could be used to enhance students' thinking abilities and their understanding of the nature of earth science and earth-environmental problems.

One of the main factors that affect the improvement of G/T education is the number and the level of quality of the professionals who are working for the gifted. The professionals vary depending on the role they play for the gifted from the classroom teacher, coordinator, to consultant. Since the legislation of the law for the enhancement of the gifted education in Korea, the in-service training for the classroom teacher has been expanded in number throughout the country. Nowadays, the gifted education is about to be expanded into the general school population, and it becomes more necessary that the training at the level of university graduate program be expanded beyond the short-term in-service training so far. In this vein, the number of universities in Korea that offer the staff development for the gifted education at the graduate level has been increased. However, the problem is whether those programs meet the need to produce the quality professionals. Based on this problem awareness, the study analyzed the graduate programs of 8 universities in Korea by comparing their course descriptions with the graduate-level training program standards of the United States and Europe. It was found that most of the universities fulfilled the areas that both standards commonly consider import, such as "concept and development of giftedness", "curriculum development for the gifted", "teaching methods for the gifted." However, the number of the offered subjects was different among the universities, which indicates that it is suspicious that the universities equally satisfy the areas both standards require. Furthermore, it was also found that the universities differ in satisfying the other standards, From these findings, several suggestions were made for the improvement of the university graduate programs in Korea.

Outdoor play for young children can promote the development of physical development, emotional development, and creativity development. However, due to safety accidents that occur in outdoor play, outdoor play is not progressed sufficiently. In this paper, we have developed smart functional educational games for AR education which can be easily used in early childhood education. In order to maximize the educational effect of the developed game and to provide customized education on the field, we conducted a focus group interview with a group of in - service child care teachers in the game design stage. Through this, we developed a functional game with AR system and verified the educational effect.

In this paper, we developed an artificial intelligence literacy education program to strengthen the AI convergence education capacity and cultivate literacy of in-service elementary and secondary teachers, and verify the effect on the degree of interest in artificial intelligence convergence education by applying it. As a test tool, the level of interest questionnaire scale developed by George, Hall & Stiegelbauer(2006) was used based on the center of interest acceptance model of Hall et al.(1979). As a result of analyzing the degree of interest in artificial intelligence convergence education before and after the application of the artificial intelligence literacy education program, the types of non-users were found both before and after the application of the program, but the overall degree of interest increased compared to before application. As a result of analyzing the satisfaction result of the artificial intelligence literacy education program, a response that was satisfied in most areas was derived, but there was a tendency to be somewhat less satisfied with the case of convergence and application of artificial intelligence and industry.

This study analyzed 3,114 articles published in KCI journals and 1,636 articles published in SSCI journals from 2000 to 2019 in order to compare domestic and international research trends of mathematics education using a topic modeling method. Results indicated that there were 16 similar research topics in domestic and international mathematics education journals: algebra/algebraic thinking, fraction, function/representation, statistics, geometry, problem-solving, model/modeling, proof, achievement effect/difference, affective factor, preservice teacher, teaching practice, textbook/curriculum, task analysis, assessment, and theory. Also, there were 7 distinct research topics in domestic and international mathematics education journals. Topics such as affective/cognitive domain and research trends, mathematics concept, class activity, number/operation, creativity/STEAM, proportional reasoning, and college/technology were identified from the domestic journals, whereas discourse/interaction, professional development, identity/equity, child thinking, semiotics/embodied cognition, intervention effect, and design/technology were the topics identified from the international journals. The topic related to preservice teacher was the most frequently addressed topic in both domestic and international research. The topic related to in-service teachers' professional development was the second most popular topic in international research, whereas it was not identified in domestic research. Domestic research in mathematics education tended to pay attention to the topics concerned with the mathematical competency, but it focused more on problem-solving and creativity/STEAM than other mathematical competencies. Rather, international research highlighted the topic related to equity and social justice.

The purpose of this study was to develop the hiring and retraining program for interior design teaching staffs of vocational high school. The survey has been made by interviewing 12 teachers from 2 vocational high school. The major finding of this stuffy are as follows; First, it is found that newly hired interior design teaching staffs are required to have interior design majors in university and minimum 1 year field experience. In case of having no field experience, it is required for them either to have an interior design associated certificates or to pass certain field test. Second, the retraining program should include drafting, perspective and rendering, architectural and interior materials, architectural structure, space and interior design, furniture design and fabrication, CAD, interior construction, housing and interior design in general. Third, the retraining program will be total 255 hours program. The number of hours for each specific subject are varied perpending on subject, For example, 15 hours an allocated for drafting and 60 hours for CAD.

This paper proposes and evaluates empirically a new recommendation method in order to improve the learning achievement of learners using case-based method. In this paper, we first carried out a survey targeting teachers who work currently in Gyeongbuk area, and constructed learning cases depending on critical factors of learning. We next recommended differentiated learning methods to learners classifying according to learning cases by achievement level through this survey. The students of a middle school took part in the experiment in order to evaluate empirically the proposed learning cases. The students were divided into three groups by their achievement level and three separate learning cases were applied to each group. The weights among learning improvement elements applying to each group were added through the survey result of teachers. The experiment using the proposed case-based recommendation method showed that the learning achievement of learners is improved considerably compared to the previous one.

Software education is drawing attention as an education for fostering future talents who will lead the 4th industrial revolution. The purpose of software education for everyone from kinder to adults is not simply to develop programming skills, but to develop "Computational Thinking," a problem-solving ability that effectively solves real-world problems based on computing. Therefore, how to cultivate and evaluate computational thinking is a very important issue. This paper proposed a method of applying a process-based performance evaluation method to evaluate computational thinking ability in the process of solving learners' problems. The developed contents were revised and supplemented through two Delphi surveys by a group of experts consisting of five university professors and five incumbent information teachers majoring in computer science and computer education to verify the effectiveness of the final model. I hope This paper can contribute to the study of evaluating computer thinking ability from the perspective of problem solving.
