According to the $7^{th}$ reform of high school education curriculum, contents on probability and statistics in mathematics of high school curriculum have been expanded compared to the previous curriculum. Thus if the curriculum contains the contents to achieve the goals for probability and statistics, more efficient education on statistics is expected to meet the needs of information age. In this thesis, we studied through network analysis if contents on probability and statistics in mathematics of high school curriculum are composed to achieve the goals. We reviewed contents on probability and statistics in mathematics of the $7^{th}$ reform of high school curriculum whether they are conformed the purpose and direction of the reform or not. As a result, the concept of probability distribution and statistical estimation with a random variable was described clearly. But, census and sample survey were not connected with other items. In a part, there were expressional mistakes.

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.

Teaching of fractions is very challengeable for elementary and middle school teachers. Many teachers feel uncomfortable teaching the subject. How shall we introduce the concept of fractions? Shall we focus more on concept development or computational procedures and skills? What methodology can be used in teaching those important topics? These are the kind of questions many teachers and researchers try to answer. In this article, the authors are to look at this issue from a cross nation perspective, by examining how the Chinese mathematics curriculum and the Chinese teachers deal with this subject.

The students in secondary schools have been taught calculus as an important subject in mathematics. The order of chapters-the limit of a sequence followed by limit of a function, and differentiation and integration- is because the limit of a function and the limit of a sequence are required as prerequisites of differentiation and integration. Specifically, the limit of a sequence is used to define definite integral as the limit of the Riemann Sum. However, many researchers identified that students had difficulty in understanding the concept of definite integral defined as the limit of the Riemann Sum. Consequently, they suggested alternative ways to introduce definite integral. Based on these researches, the definition of definite integral in the 2015-Revised Curriculum is not a concept of the limit of the Riemann Sum, which was the definition of definite integral in the previous curriculum, but "F(b)-F(a)" for an indefinite integral F(x) of a function f(x) and real numbers a and b. This change gives rise to differences among ways of introducing definite integral and explaining the relationship between definite integral and area in each textbook. As a result of this study, we have identified that there are a variety of ways of introducing definite integral in each textbook and that ways of explaining the relationship between definite integral and area are affected by ways of introducing definite integral. We expect that this change can reduce the difficulties students face when learning the concept of definite integral.

Korea, where the national curriculum is run, can change school education by specifying basic competence in the common curriculum of elementary and middle schools for students to pursue school learning and real life. The numeracy as a basic competence should not be limited to mathematics, so it needs to be specified in the national curriculum covering several subjects and guided through various subject curriculums. To this end, the study proposed concepts, components, and levels of numeracy and proposed ways to reflect them in the national curriculum and other subjects' curricula. To ensure its validity, the UK, Canada and Australia curriculum are analyzed, and the results of the survey are proposed for various education experts. This study proposed two ways to briefly state the numeracy in the national curriculum and to imply the contents related to the numeracy in each subject curriculum, and to present the concepts, components and levels of numeracy in the national curriculum in detail and to describe numeracy code in each subject curriculum. These suggestions obtained high consent from experts.

This research is that concern in mathematics education of Technical high school Department of Electricity in the 7th educational curriculum. Indicated problem of mathematics education of Technical high school Department of Electricity at 7th educational curriculum as that compare mathematics subject contents with difference of Technical high school mathematics education in the 6th and the 7th educational curriculum. And examine major subject contents, analyzed contents of mathematics that must supplement and mathematics which use in major subject. Established contents of electricity mathematics education that need to major learning to satisfy target of technical high school technical education that is presented in the 7th training courses with this analysis

Since modern mathematics textbooks were introduced in the late 19th century Korea, arithmetic experts started to teach modern mathematics using Arabic numerals at village schools and churches. After the Gabo Education Reform of 1894, western mathematics education was included in public education and the mathematics textbooks began to be officially published. We explored most of Korean mathematics textbooks from 1895 to 2016 including the changes of mathematics curriculum through 1885-1905, 1905-1910, 1911-1945, 1945-1948, 1948-1953, 1954-1999, and 2000-2016. This study presents the characters of modern mathematics textbooks of Korea since 1885.

The purpose of this paper is to show how much the subjects based on the mathematics and statistics contribute to the curriculum and the education of the students majoring in engineer of the Computer-Software department, and to recognize the roles of mathematics and statistics in the Computer-Software department. In order to advance the world-class Computer-Software department, it is necessary for Math/Stat to ensure the role as a basis for the Computer-Software majors as well as to extend its role to relate the core studies of the Computer-Software majors. Consequently, the recognition of Math/Stat in the Computer-Software major will enable to establish the short or/and long-tern plan for student education.

Researchers have been attending to the potential of curriculum materials as resources for professional development. In order for a curriculum material to fulfil such purpose, curriculum authors should intentionally attend to educativeness of the material. A feature of educative material is that its voice speaks to teachers. In this study, I explore educativeness of Algebra teacher guides by attending to their voice. In particular, I focused on the use of pronouns, modality, and imperatives. Findings indicate that some teacher guides have more educative voice than the others and that the amount each guide talk to teachers were less than sufficient. Implications for future research and practice are discussed.
