The purpose of this study was to analyze the trends of domestic research on teacher knowledge in mathematics in terms of its conceptualizations of teacher knowledge, topics, methods, subjects, and content domains. For this purpose, the papers published in 9 professional journals during the recent 14 years (1999-2012) were analyzed by 5 criteria. The results of this study showed that the concept of PCK was the most frequent, whereas its subcategories appeared in different forms. The most frequent research topic was survey of teacher knowledge. The qualitative research methodology was more frequently used than the quantitative methodology, whereas mixed one was hardly used. The subjects for research included a little more elementary school teachers than secondary counterparts, but did similarly both pre-service and in-service teachers. Whereas both the research on number and operations in elementary mathematics education and the research on function in secondary were active, the rest of content domains were not. On the basis of these results, this paper provides several implications for future research direction in teacher knowledge in mathematics.

Recently, various attempts have been made to change traditional lecture classes such as flipped learning and blended learning, and their effectiveness has been verified in various fields. On the other hand, the 2015 revised curriculum enables students to participate in self-directed learning by encouraging student participation. Teachers should also try to change the teaching method, and to improve the teaching methods by confirming the advantages and disadvantages of such new teaching methods in accordance with the demands of the times. The purpose of this study is to analyze the case of applying Blended learning class to teach mathematics education for elementary education 1 class which is one of the required subject in university of education.

The purposes of this study are to identify how university's entrance examination system is related to private education, and to explore how to improve the university of education entrance system in order to reduce private education costs. For these purposes, 116 teachers of senior students in high school in Daegu and Gyeongbuk and 107 pre-service teachers who had experienced the entrance of the university were surveyed in order to find out the perception of the relationship between admissions elements and private education. As a result, it is possible to concentrate more on school education by strengthening high school grades in the entrance examination. However, there was other opinion that the strengthening high school grades in the university entrance could lead to the further increase in the cost of private education. As there are big differences in the perception of the screening factors between rural areas (Gyeongsangbuk-do) and large cities (Daegu), it is necessary to introduce the entrance examination system considering the characteristics of each region. Third-year teachers in high schools argued that university admissions should reduce the rate of the College Scholastic Ability Test (CSAT) and increase the rate of interviews. The results of this study suggest that the improvement of the university entrance examination system to reduce the cost of private tutoring requires securing fairness of document evaluation, strengthening interviews, and opening interview questions.

The purpose of this study was to design a 'Form of Abduction' which is the 'guide form used in generating hypothesis through abduction', and to analyze the features of the hypotheses generated with the 'Form of Abduction' compared with those generated without any special guide form. Through a review of Peirce's literature regarding the meaning and frame of abduction, a 'Form of Abduction' was designed as a three step format as follows: (i) writing down what is doubted, (ii) wiling tentative explanations which replace what is doubted with what is believed, (iii) writing the tentative explanations as hypotheses. The thirty four pre-service elementary teachers were asked to generate hypotheses without a 'Form of Abduction' at first, and then were asked to do so again using the form. The results of analysing the features of the hypotheses were as follows: in the case of using a 'Form of Abduction', firstly, the types of misunderstanding or mis-adapting the meaning of hypothesis were found to be rare, and secondly, the types of 'giving explanation about the cause of problematic situations through analogical inferencing from the existing knowledge' were found to be double the rate of when no special guide form was used. In conclusion, the hypotheses generated with the 'Form of Abduction' had the features of satisfying the original meaning of hypothesis, i.e. 'explaining the cause of phenomenon and leading to knowledge expansion'. These results also showed that using a 'Form of Abduction', although its form was simple, could be a way of helping students generate hypothesis properly in science classes.

In this study, we reviewed educational trend of Puzzle-Based Learning Contents and case studies at domestic and international, and have developed Puzzle-Based Learning Contents with the contents using fundamental concepts of computer science. Thirty one prospective elementary school teachers were applied to this contents, total thirty two sessions for four months, and Torrance Tests of Creative Thinking(TTCT) verbal and figural tests were performed to evaluate the changes in creativity. The result showed that there were significant improvements in two subscales of verbal creativity, verbal creativity index, and three subscales of figural creativity, figural creativity index. In this paper, on the basis of proven effectiveness, we introduce the Puzzle-Based Learning Contents as the alternative computer science education.

As a way to improve the software education ability of the pre - service teachers, we conducted programming learning using two types of programming tools (Python and Scratch) at the regular course time. In programming learning, various types of errors, which are factors that continuously hinder interest, achievement and creativity, were collected and analyzed by type. By using the analyzed data, it is possible to improve the ability of pre-service teachers to cope with the errors that can occur in the software education to be taught in the elementary school, and to improve the learning effect. In this study, logic error (37.63%) was the most frequent type that caused the most errors in programming in both conventional language that input text and language that assembles block. In addition, the detailed errors that show a lot of differences in the two languages are the errors of Python (14.3%) and scratch (3.5%) due to insufficient use of grammar and other errors.

Educating qualified elementary school teachers depends on excellent pre-service education. The high quality of education is accomplished by various interactions between teachers and learners, as well as active participation by students. In the present study, online problem-based learning and an e-portfolio were used to examine the effect on the computer-curriculum education to reflect social and individual needs, and to enhance the quality of instruction at universities. Students (n=105) participated in six different problem-based learning sessions. At the same time, they developed Blog e-portfolios as individual and group products, and wrote reflective journals that focused on their learning processes and results. A qualitative analysis method was employed to analyze the reflective journals. The results of the analyses showed the following: 1) Increasing the understanding of the computer-curriculum education, 2) enhancing students' competence in using ICT potentially, 3) cultivating student-centered teaching and learning strategies on ICT, and 4) enhancing competence of future teaching activities through experiencing e-portfolio as a performance-assessment tool.

In this study, I explored the possibility of using ChatGPT math education. For this purpose, students' problem-solving outputs and conversation data between pre-service teachers and a student were selected as an analysis case. A case was analyzed using ChatGPT and compared with the results of mathematics education experts. The results that ChatGPT analyzed students' problem-solving strategies and mathematical thinking skills were similar to those of math education experts. ChatGPT was able to analyze teacher questions with evaluation criteria, and the results were similar to those of math education experts. ChatGPT could also respond with mathematical theory as a source of evaluation criteria. These results demonstrate the potential of ChatGPT to analyze students' thinking and teachers' practice in mathematics education. However, there are limitations in properly applying the evaluation criteria or providing inaccurate information, so the further review of the derived information is required.

Ray drawing in geometrical optics is an effective method for visible imagery of light. In this study, we developed peer instruction materials for in-service teachers' training concepts on the refraction of light including drawing rays. And then we applied these programs to 29 pre-service teachers and 21 in-service primary teachers and evaluated the degree of conceptual change in correct points from the pretest and the post one. As a result of pretesting, in spite of experiences for learning this topic in elementary and secondary education courses, most participants in the study did not well understand the path of refracted light before instructions. However, the result of post testing after the application of peer instruction materials shows that they have practiced ray drawing, which is helping visible imagery. Accordingly, in learning geometrical optics, we suggest that peer instruction with ray drawing activity for teachers' training program would be effective. We also suggest that similar approaches would be applied to other context.
