This study investigated the influences of an instructional method related to problem solving. The new instruction consists of a four-stage problem-solving strategy emphasizing 'planning' and 'checking' stages, and a think-aloud paired problem solving in order to check students' performances in solving problems. Two high school classes (n=91) were randomly assigned to the treatment and the control groups. Prior to the instructions. students' perception of involvement and self-efficacy were examined, and their scores were used as covariates in the analysis. Students' problem-solving ability, perception of involvement. and self-efficacy were examined after the instructions. The test scores of the treatment group were significantly higher than those of the control group in the problem-solving ability and the perception of involvement. However, there was no significant difference between the scores of the two groups in the self-efficacy.

The purpose of this study was to examine the change in the classes of beginning science teachers through the collaborative mentoring program that induce reflective thinking practice. Participants in this study were three mentor-teachers, two teachers in doctor's or master's course, one university professor, and three mentee-teachers who have less than four years of teaching experience. We collected data such as video recordings of the mentee-teachers' classroom teaching and transcription, lesson plans, recording of one-on-one mentoring and transcription, mentor and mentee's journals, and RTOP classroom teaching observation reports. RTOP was used for the analysis of classroom teaching and mentee-teachers' recognition and changes in their classes were found out through journals and one-on-one mentoring interview materials. According to mentee-teachers' recognition and changes in their classes during the mentoring program, they themselves recognized their teacher-centered teaching style, misconception, and lack of content knowledge. Furthermore, there were changes in the mentee-teachers' classroom teaching through their reflective practice and improvement. As a result of this study, the interactions with mentor-teachers through collaborative mentoring program stimulated mentee-teacher's reflections on their teaching. Therefore, these reflections led to their reflective practice that showed progressive changes in their teaching behavioral activities. The extent of these changes varied according to the mentee-teachers' individual disposition toward reflection and the issue of whether mentee-teachers' reflective practice was in accordance with priorities in motivational ZDP or not. Also based on the results of this study, the teachers' reflection was not all accompanied by reflective practice even if the beginning science teachers made some partial changes in reflective practice through reflection. It means that it is hard to lead reflective practice for mentee-teachers through mentoring in a short period of time. Therefore, we consider that a systematic and long-term mentoring program is necessary for beginning science teachers.

Recently, research using robots as a learning tool has increasingly been conducted in K-12 education area. It has been known that hands-on robots give positive educational effect not only on science and mathematics, but on STEAM activity, and help improve the abilities necessary in the 21 century, such as critical thinking, creativity, communication skills, and team work. Despite many research achievements, there is still few research on robot based curriculum to improve the instrumental application of robots in the primary and secondary education fields. In other words, there is a lack of studies of systematic educational contents, educational methods and educational evaluation to increase the instrumental application according to schools and class years. Therefore, this study analyzed domestic and foreign robot based curriculums and relevant cases to develop 'robot' related educational programs in primary school and middle school, suggested the achievement objectives in the robot area as a sub category of the computer science curriculum which will be revised, and proposed teaching-learning method and evaluation method.

Since most people experience mathematics anxiety(MA), the research on mathematics anxiety has been the main theme in the research of mathematics education. The study of brain science related to MA has recently been begun due to the advent of apparatuses so this study might have revisited MA as time passed and aimed to obtain realistic implications for the future study. For this purpose, we analyzed previous studies how to measure MA and how to develop the intervention to reduce MA. As the result, the researchers based on brain science studied the relevance of specific parts of the brain according to the degree of MA using only simple computational tasks. The research for developing the MA scale has upgraded how to measure both the cognitive and affective domains with more efficient ways. The research on intervention for MA has developed the programs using systematic desensitization, clinical counseling, STAD teaching method, writing methods, etc. However, we realized that more specified and reliable studies to solve the MA must be done in the future.

Valid and effective science education would require research-based decisions on multiple aspects of science education including policy decisions, science curriculum development, designing teaching resources and methods. However, this has not been the case. In order to provide a research base for science education practices and policy-making, this study reviewed research articles published in major science education research journals in South Korea in the last ten years. The analysis was focused on 8 areas including student conceptions, student thinking, inquiry, affective domain, student ideas about science, science curriculum, students' learning and classroom activity, and student learning in informal settings. General research trends found include: First, science education research conducted for the past decade focused on a certain limited topics/areas. Second, research participants were also limited to certain grade levels or types of students. Third, rather than examining developmental processes descriptive research was prevalent. Fourth, there was a lack of research on developing new areas of study or research on generation of new perspectives, theories or tools. Fifth, many studies were related to school science learning while relatively less studies were about other areas that would impact students' future. Based on the results, we suggest several implications for science curriculum development, policy development, science teaching and learning resources, and others.

This study, as an attempt to integrate mathematics and information for convergence education, was conducted to develop teaching-learning materials on mathematics education combined with coding education, which has recently been emphasized. We chose the subject of digital signature for coding education, and used SageMath as a coding program. In this study, we overview mathematics used in the elliptic curve digital signature algorithm, one of the many methods for digital signature, and developed the teaching-learning materials on the algorithm for mathematics education integrated with information education based on coding. The elliptic curve digital signature algorithm utilized in transactions of Bitcoin, which many people recently are interested in, is a good example, showing students that mathematics is applied to problem-solving in the real world and provides an optimal environment for implementation by coding. Accordingly, we expect that a class on algorithm will provide a specific teaching-learning program to achieve the goal of integrated mathematics education. By comprehensively considering the opinions of mathematicians, mathematics teachers and mathematics education experts, we expect that the teaching-learning program will be realized as a meaningful class in science high schools, high school's math clubs, and 'number theory' class in colleges.
