The objective of this study is to explore the meaning generated through discourse in three different types of 1st-grade middle school textbooks in Korea and CMP textbook in the United States, specifically focusing on histograms. Through a discursive perspective, the study aims to analyze the characteristics of questioning within the stages of statistical problem-solving found in histogram tasks. The findings highlight several significant points. Firstly, variations exist in the definitions of histograms between Korean and US CMP textbooks. Secondly, diverse discursive structures contribute to the interpretation and understanding of histograms in textbooks. Thirdly, limitations are observed in the stages of statistical problem-solving reflected in histogram tasks. Lastly, distinctions are identified in the types of questioning employed in histogram tasks between Korean and US CMP textbooks. Building on these insights, the study suggests concrete ideas for enhancing the process of defining histograms and refining the questioning in histogram tasks.

This study is focused on the trends in education and polices for women in Korea. First, historical background of education for women in Korea revealed that a biased view of education for women was deeply rooted. Next, several findings such as international comparison of performance on the PISA, TIMSS, and National Assessment including gender differences especially in Mathematical and Science performance were analyzed. In international assessments, female students perform better in reading literacy, but still fall behind male students in mathematical and scientific literacy, and the gap between the genders are wider than most OECD countries. The change in status of women in contemporary Korea is examined focusing on educational system and women's educational and vocational performance, etc. Additionally, policies planned by Ministry of Science and Technology which show the many execution plans for training and supporting female professionals were presented. Finally, possible reasons for gender differences in educational performance is examined and some suggestions are provided to reduce the gender gap in mathematical and scientific literacy of Korean students.

로봇은 지식기반사회에서의 요구하는 기초 능력과 문제해결력 함양을 위한 학습을 충족시켜줄 것으로 기대된다. 또한 로봇교육은 공학적으로 여러 기술이 관련되어 있으므로 통합적인 기초 교육이 가능하게 할 것이다. 그러나 학습 내용, 학습 방법 및 학습 교재에 대한 연구가 부족하므로 외국에서 실시하고 있는 로봇교육과정을 분석하였다. 해외 사례 분석 결과 로봇을 통해 기초 능력과 문제해결력을 함양하기 위한 교육목표를 체계적으로 달성하기 위해서는 학교 교육과정으로 운영되어야 하며 로봇의 특성과 관련된 과학, 수학, 기술, 공학의 내용 요소들을 추출하며 로봇소양에 대한 내용뿐만 아니라 로봇활용에 대한 내용으로도 구성해야 하며 로봇 창작 시스템을 이용하여 단순한 로봇 조립보다는 창작 및 프로그래밍의 과정이 이루어질 때 효과적으로 학습의 성과를 거둘 수 있을 것이다.

The Ministry of Education (2015) announced the "2015 Revised Curriculum for Elementary and Secondary Schools" and announced that SW (Software) training for elementary and junior high school students to develop Computational Thinking will be gradually introduced from 2018. In addition, 'problem solving' and 'programming' have become important areas. Furthermore, the ability to analyze and utilize big data is becoming more emphasized. We developed and applied the statistical - Python programming convergence curriculum based on the idea that convergence education combining information and mathematics, programming and statistical literacy is needed according to current trends. Before and after the experiment, problem solving ability test and programming / mathematical interest test were conducted and compared with the corresponding sample t-test. According to the analysis results, there were significant differences in the pre- and post-test on problem solving ability, programming interest and mathematical interest at the significance level of 0.05.

The purpose of this study is to develop students' creativity and artistic sensitivity by developing a convergence education program that links various subjects, including mathematics, science, and art based on design. Design is done in almost every human activity that pursues beauty and implements cultural value through patterns and images. We have developed three programs for elementary school students and two programs for middle school students, taking into consideration the achievement standards and curriculum content appropriate for the 2015 revised curriculum. It was assessed by a panel of five educational experts during the development and demonstration courses to evaluate the feasibility of the development program. The development program can enhance the design literacy and design sense of elementary and junior high school students and can be used convergent educational contents that can be applied in the free-semester system activities of junior high school. Through this program, adolescents who will lead the future design society will be able to acquire the sense of design, literacy, and design ability as design consumers and producers.

Mathematics was the main domain of PISA 2012, and both paper-based and computer-based assessment of mathematics (CBAM) were conducted. PISA 2012 was the first large-scale computer-based mathematics assessment in Korea, and it is meaningful in that it evaluated students' mathematical literacy in problem situations using dynamic geometry, graph, and spreadsheet. Although Korea ranked third in CBAM, the use of ICT in mathematics lessons appeared to be low. On the other hand, this study focused on Singapore, which ranked first in CBAM. The Singapore Ministry of Education developed online programs such as AlgeTools and AlgeDisc, and implemented the programs in classes by specifying them in mathematics curriculum and textbooks. Thus, this study investigated influential factors on computer-based assessment of mathematics by comparing the results of Korea and Singapore, and aimed to provide meaningful evidence on the direction of Korea's ICT-based mathematics education. The results showed that ICT use at home for school related tasks, attitudes towards computers as a tool for school learning, and openness and perseverance of problem solving were positively associated with computer-based mathematics performance, whereas the use of ICT in mathematics class by teacher demonstration was negatively related. Efforts are needed to improve computer use and enhance teaching techniques related to ICT use in Korean math classes. Future research is recommended to examine how effectively teachers use ICT in mathematics class in Singapore.
