The EBS teaching coaching program, '선생님이 달라졌어요' broadcasted about 30 dramatic teaching improvement cases. The TV program has gained great attention and been used widely as a good example for making some meaningful improvements in teaching. However, there has not been an attempt to research and gather the series beyond the individual coaching examples for the viewers (mainly teachers) to obtain more comprehensive educational insights of the results. This study, therefore, reviews the program and conveys how the overall coaching actually took place, examines changes in classrooms, and discusses the implications the results with theoretical foundations. The researcher selected 12 teachers' coaching cases among 30 ones. Then the reviewers reviewed the program with the 6 categories. According to the results, the coaching took place 6-8 months for each individual teacher. The common difficulty teachers shared was a big gap between teachers' effort for teaching versus 'students problematic behaviors' in class. The overall direction for the coaching solution was 'to improve the relationship with students' first rather than to mainly focus on teaching the content. Students changed and actively participated in the learning process when teachers improved their relationships with the students. The researcher discussed how building good relationships with students greatly affects the improvement in teaching with the 'Needs Hierarchy' and 'Brain Science' theories.

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.

This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.

Despite the importance of mathematics education, many students in high school have lost their interests and felt difficulties and they don't have 'mathematical' experience with meanings attached because of the entrance examination. This paper attempted to resolve these problems and find the teaching-method with which students can study by themselves with more confidence. Nowadays students' use of Internet is very popular. After develop 'the development of mathematical power' program based on mathematics history, history, science, the application of problems in real world, and self-evaluation, I made students repeat them after making teaching lessons in classroom as moving pictures. Through this processes, I attempted to develop the Self-Directed Learning' ability by making public education substantial. First of all I analyzed the actual conditions on 'Self-Directed Learning' ability in mathematics subject, the conditions of seeing and hearing in Internet learning program, and students' and their parents' interests in Internet education. By analyzing the records, I observed the significance of the introducing mathematics history in mathematics subject in early stager, cooperative-learning, leveled-learning, self-directed learning, and Internet learning. Actually in aspect of applying 'the development of mathematical power' program, at first I made up the educational conditions to fix the program, collected the teaching materials, established the system of teaching-learning model, developed materials for the learning applying Internet mail and instruments of classroom, and carried out instruction to establish and practice mathematics learning plan. Then I applied the teaching-learning model of leveled cooperation and presentation loaming and at the same time constructed and used the leveled learning materials of complementary, average, and advanced process and instructed to watch teaching moving pictures through Internet mail and in the classroom. After that I observed how effective this program was through the interest arid attitude toward mathematics subject, learning accomplishment, and the change of self-directed learning. Finally, I wrote the conclusion and suggestion on the preparation of conditions fur the students' voluntary participation in mathematics learning and the project and application on 'the development of mathematical power' program and repeated learning with the materials of moving pictures in classroom.

Developing computational thinking ability is crucial for those living in the 21st century. However, the current computational education system cannot satisfy this need. Current computational education tends to be limited to the teaching of the use of application programs or the teaching of the programming language. This is why the primary puzzle-based learning program was developed. This program promotes the development of the learner's computational thinking ability and understanding of the principles of the computer science as opposed to the fragmented, uniform programing education. In order to prove the effectiveness of this newly developed program, a 35-hour study was conducted to 41 students from grade 3 to 6 classrooms in Jeju Province. It was proved that this program brings positive changes in creativie problem-solving ability and problem-solving abilities in computer science. This paper is to provide the ground for the development of an educational program and to prove the effectiveness of thereof, and finally introduce the Primary Puzzle-Based Learning Program as the alternative computational education.
