The purpose of this study is to provide base line data to the educational settings so that more improved occupational core competencies could be taught under the formal curriculum of the technical highschool than before through the inquiry into 'the need for the consolidation of education that principals of technical highschool perceive'. Initial occupational key competencies had been prepared through the literature review on the occupational core competencies and the review on the key competencies by the experts in the field of technical industry had been performed to achieve the purpose of this study. The survey instrument consisting of final 9 occupational key competencies had been developed with the careful consideration for the calculation of the need for the consolidation of education using the Borich's model. The results show that principals for the technical highschool perceive the strong need for the educational consolidation regarding the all 9 occupational core competencies in the whole. However, for the specific key competency of understanding the organization and the mathematical competency, the principals of the technical meister highschool perceive somewhat differently from the principals of the specialized technical highschool. The principals in the meister highschool perceive not much need for the consolidation of education regarding the competency of understanding the organization and the mathematical competency.

The purpose of this study is to investigate the international trends of how the core competencies are reflected in mathematics curriculum, and to find the implications for the revision of Korean mathematics curriculum. For this purpose, the curriculum of the 9 countries including the U.S., Canada(Ontario), England, Australia, Poland, Singapore, China, Taiwan, and Hong Kong were thoroughly reviewed. It was found that a variety of core competencies were reflected in mathematics curricula in the 9 countries such as problem solving, reasoning, communication, mathematical knowledge and skills, selection and use of tools, critical thinking, connection, modelling, application of strategies, mathematical thinking, representation, creativity, utilization of information, and reflection etc. Especially the four most common core competencies (problem solving, reasoning, communication, and creativity) were further analyzed to identify their sub components. Consequently, it was recommended that new mathematics curriculum should consider reflecting various core competencies beyond problem solving, reasoning, and communication, and these core competencies are supposed to combine with mathematics contents to increase their feasibility. Finally considering the fact that software education is getting greater attention in the new curriculum, it is necessary to incorporate computational thinking into mathematics curriculum.

영재의 특성은 다양한 분야에 대한 관심과 재능을 가지고 있으며 지적 호기심에 대한 도전의식이 강하다. 영재교육프로그램은 이러한 영재들의 지적호기심을 자극하여 영재로서 갖추어야할 제반 능력들을 균형 있게 길러 줄 수 있어야한다. 그러나 현재까지 개발된 대부분의 영재교육프로그램들은 여전히 논리와 이론을 중시하여 수리능력, 창의적 문제해결력 등 대부분 지적 능력신장에 치중하는 경향이 있다. 이러한 프로그램만으로는 교과별 학습을 통하여 얻게 되는 개념과 원리들을 생활과 관련지어 이해하거나 다양한 분야에 적용하는 능력을 길러주는데는 한계가 있다. 따라서, 영재아들의 잠재능력을 계발하고, 교과간의 연결능력을 길러 새로운 분야를 창의적으로 개척할 수 있는 능력을 신장하기 위해서는 수학분야에 집중된 주제를 다루기보다는 개방적인 주제를 다루는 간학문형 프로그램 개발이 필요하다. 본 연구에서는 수학분야나 지적영역에만 국한되는 편협성을 탈피하여 보다 창의적인 역량(creative competency)을 신장할 수 있는 수학과 관련성이 있는 간학문형(間學文型, inter-disciplinary)프로그램 개발 방안과 그 사례를 제시하고자한다.

To combine the science and technology creativity necessary in the era of the 4th Industrial Revolution, it is necessary to cultivate talents who can discover new knowledge and create new values by combining various knowledge with self-directed mathematical competencies. This research attempted to lay the foundation for the curriculum for fostering future creative convergence talent by preparing, executing, and reflecting on the learning plan after learners themselves understand their level and status through self-directed learning. Firstly, We would like to present a teaching-learning plan based on the essential capabilities of the future society, where the development of a curriculum based on mathematics curriculum and intelligent informatization are accelerated. Secondly, an educational design model system diagram was presented to strengthen the self-directed learning ability of mathematics subjects in the electronic engineering curriculum. Consequently, through a survey, we would like to propose the establishment of an educational system necessary for the 4th industry by analyzing learning ability through self-directed learning teaching methods of subjects related to mathematics, probability, and statistics.

There is no single definition of mathematical creativity. But creativity is a key competency to adapt and live in the future. So, there are so many attentions to develop students' mathematical creativity in school mathematics. In special, mathematical problem posing activity is a good method in enhancing mathematical creativity. The purpose of this paper is to analyse on the students' mathematical creativity using problems which are made by students in problem posing activities. 16 children who consist of three groups(high, middle, low) are participated in this study. They are trained to make the problem by Brown & Walter's 'What if not' strategy. The results are as follows: Total creativity is proportional to general achievement levels. There is a difference total creativity between items contents. The number of problems differs little according to the general achievement levels. According to the qualitative analysis, students make the problems using the change of terms. And there is no problem to generalize. Based on this paper, I suggest comparing the creativity between problem posing activity and other creative fields. And we need the deeper qualitative analysis on the students' creative output.

This study constructed an experiment group and a comparative group, composed of high school students preparing for "Na" type math exam and provided one-to-many tutoring cooperative learning. This study tested the differences between group and between pre- and post-treatment scores by group using non-parametric statistics techniques. Moreover, this study conducted an open-type survey twice and had individual interviews to examine the affective domains of students. The difference in scores between the experimental group and the comparative group was not significant. However, the difference between pre- and post-treatment math scores was only significant in the experiment group among the three groups. Additionally, the student-teacher could reflect on him or her and improve self-efficacy while teaching other ordinary students. The ordinary students were more interested and motivated in the lessons and became more confident. In terms of mathematics competency, we could see that communication, problem-solving, reasoning, and attitude & practice were improved.

As the 2022 revised mathematics curriculum emphasizing competency cultivation was announced, the researcher analyzed the connection between competency, content system, and achievement standards in elementary school mathematics curriculum. The results of the analysis of the link between the competency of the curriculum revision research report, its sub-elements, the 'process and skills' of the curriculum content system, and the achievement standard verb are as follows. First, most of the five curriculum competencies (problem solving, reasoning, communication, connection, and information processing) of the mathematics department are implemented as "process-skills" of the content system, which is further specified and presented as an achievement-based verb. Second, the five competencies were not implemented with the same weight in all areas, and the appropriate process-skills were differentiated and presented according to the content of knowledge-understanding by area/grade group. Third, verbs of the achievement standards were more rich than before in the 2022 revised elementary school mathematics curriculum. Fourth, 'understanding' throughout the entire area was still presented as the highest proportion. Through the research results, the researcher discussed clearly establishing the meaning of problem-solving capabilities in the future and developing and presenting "understanding" as a more specific process or skills.

In this study, considering the OECD's DeSeCo and 2030 projects, the curriculum to develop competency was expected to be more emphasized, and the evaluation standards of the 2015 revised mathematics curriculum for elementary school in Korea and the Australian curriculum were analyzed in depth. To this end, the capabilities newly emphasized in the OECD 2030 Project were examined in detail and examined how the Australian elementary school mathematics curriculum included capabilities in achievement standards and content descriptions. The achievement standards of elementary school mathematics curriculum in Korea and Australia were matched, and the contents of number and arithmetic domain were compared and analyzed, and the skill verbs included in the achievement standards were analyzed and compared to see how their competencies were reflected in the achievement standards. Based on the results of the analysis, implications for improving math achievement standards were derived to faithfully reflect the capabilities into the mathematics curriculum.
