In this study, we present an analysis framework based on the 2015 revised curriculum to analyze how mathematical contents and achievement standards for domains of numbers and computations have changed in the curriculum of elementary mathematics in Korea. Based on this, we classified the achievement standards by type and investigated their characteristics. The achievement standards for numbers and computations can be divided into the successive, the extinctive, and the additive achievement standards depending on their characteristics. The successive achievement standards are the ones that have consistently existed without being removed from the 1-st curriculum to the latest revision in 2015. The extinctive achievement standards are the ones that have been removed at some point during the revisions of nine times and do not remain in the current revision in 2015. The characteristics of the extinctive achievement standards were analyzed to be different before and after the 4-th curriculum. The additive achievement standards refer to the ones that have been newly added to the curriculum or that have been removed at a certain moment but added back in later and thus exist in the current revision in 2015. The characteristics of each type according to the changes of the achievement standards can be thought to be the results that the revision for the mathematics curriculum in Korea has been faithfully conducted. Based on the results of this study, we suggest some implications for organizing the achievement standards in the future curricular development.

The purpose of this study was to analyze the characteristics of students' academic achievement of middle school science curriculum achievement standards in the 2009 revised national curriculum and to generate implications for curriculum improvement. Based on the results of the 2015-2018 National Assessment of Educational Achievement (NAEA), we analyzed middle school students' mastery of 84 curriculum achievement standards. In the analysis, we used representative item information by achievement level and correct answer rate and checked the validity of the determination of mastery. According to the results of the analysis, 15 of the 84 achievement standards could not determine the degree of achievement. In science, many achievement standards could be mastered only by above-average group students. By achievement level, there were six achievement standards that advanced achievement-level students did not achieve, 38 achievement standards judged to represent mastery by advanced achievement-level students, 23 achievement standards judged to represent mastery by proficient achievement-level students, and two achievement standards judged to represent mastery by basic achievement-level students. By content area, the number of achievement standards corresponding to advanced and proficient levels was similar in the areas of motion and energy and earth and space domains. In the material and life domains, there were more achievement standards corresponding to advanced levels. Accordingly, it is necessary to reinforce customized teaching and learning activities in relation to achievement standards that were under-achieved.

This article examines psychological factors that contribute to educational achievement of Korean adolescents. By reviewing empirical research, three core areas are outlined. First, positive and negative roles that Korean society play on academic achievement are analyzed. Compared to other countries, Korean society places a high premium, pressure an investment on educational achievement. This has contributed to the rapid economic growth and development, but at the same time it has created numerous social problems. Second, psychological and relational dynamics of investing in and achieving success in education are delineated. Through indigenous psychological analysis, the role parents play in motivating and regulating their children to succeed academically is reviewed. In addition, the role of teachers and friends and the coordinated efforts of Korean society are outlined. Third, future directions and transformations in education that are needed in Korean society are discussed. Although Korean adolescents are high achievers in high school, this is not the case at the university level. Since Korean students are interested in entering a prestigious university, they have developed skills in doing well in standardized tests. Educational reforms need to take into consideration individuals' personal interests, skills and creativity to ensure that the knowledge that they acquired can be used to further their career and improve their subjective well-being. Educational transformation does not imply simply adopting Western models, but developing indigenous models that can maximize human and cultural potential and stimulate curiosity, diversity and creativity that are necessary in the global era.

In this study, we analyzed how the content and achievement criteria of the Geometry domain of Korean elementary school mathematics curriculum have changed. To this end, based on the analysis framework based on the 2015 revised curriculum, the achievement standards for each period were classified into continuous, extinct, and additional types, and their characteristics were examined. In the domain of Geometry, continuous achievement standards accounted for 51% of the total, and there were many achievement standards that remained unchanged in grade and domain. The extinctive achievement standard is 20.4% of the total, and the mathematics contents that were rapidly introduced due to the modernization of mathematics in the 3rd curriculum were eliminated the most from the 4th curriculum, and after the 7th curriculum, With the introduction of staged curriculum and the system of school year group, the contents of learning were either integrated or moved to middle school. The additional achievement standard was 28.6% of the total, and the achievement standard was added the most with the introduction of spatial sensory development in the 7th curriculum. The GAct that the additivel achievement standard is more than the extinction achievement standard in the Geometry domain is the result of the efforts to actively introduce the geometric contents appropriate to the times despite the great flow of curriculum revision of the curriculum reduction. It is hoped that the results of these studies will be used as basic data in the formation of new achievement standards in future curriculum development.

A characteristic of the national mathematics curriculum revised in 2007 is to repeal the level-oriented individualized curriculum and choose substance of individualized teaching and learning based on the student's achievement level and quality. To do this we first have to think through how to compare students' achievement and differentiate classes. In this paper, we introduce the (modified) Angoff method as a method for comparing students' achievement and the concept of representative items for each achievement level in the National Assessment of Educational Achievement of Mathematics, and discuss how to use them in individualized teaching and learning, especially comparing students' achievement.

This study analyzed the effects of the educational contextual variables on fourth grade students' mathematics achievement in five East Asian countries(Singapore, Hong Kong Taiwan, Japan and Korea) using TIMSS 2015 data. There are four findings of this study. The first is that the common student-home-level variables that give significant influence on the mathematics achievement in all 5 countries are 'Home resources for learning' and 'Parents' educational expectations'. But 'Literacy and numeracy activities before entering a school' and 'Parents' attitude for mathematics and science' are not common variables. The second is that 'Students' interest in math learning' gave significant influence on the mathematics achievement of in all 5 countries. The third is that 'Teaching limited by student needs' does not give significant influence on the math achievement in Korea, Taiwan, and Japan but in Singapore and Hong Kong. The fourth is that 'Student economic background' gave more significant influence in Korea, Taiwan, and Japan than Singapore and Hong Kong. Suggestions to improve elementary school mathematics teaching and learning are discussed in the conclusion.
