The current 2007 Mathematics Curriculum in Korea emphasizes mathematical problem solving, advanced mathematical thinking and effective mathematical communicating. Therefore, in order to assess and evaluate these important thinking attributes, performance evaluation using descriptive and essay type of assessments are emphasized. In this paper, analysis of the elementary mathematics curriculum is used to develop descriptive assessment problems and grading rubrics that could be used objectively and consistently by teachers of the grade 6 school mathematics. The assessment problems were developed, pilot tested, revised, implemented and analyzed in detail to understand the overall effectiveness of the descriptive evaluation method in school mathematics.

Mathematics anxiety is a term for emotional and physical resistance to mathematics. Understanding students' mathematics anxiety is important not only in terms of improving mathematics academic achievement, but also in nurturing mathematics manpower necessary for the future society. In particular, mathematics anxiety is most likely to occur in elementary school, and it has a negative effect on subsequent learning. Therefore, it is important to understand the aspects of students' mathematics anxiety in elementary school. In this study, I presented the patterns of changes in students' mathematics anxiety over time and statistically verified them. As a result of a follow-up survey of 249 elementary school students' mathematics anxiety for 3 years from 4th to 6th grade, it was found that, rather than having a special pattern related to the formation of math anxiety, it may increase and decrease and vary depending on individual confirmed. Later, in this study, five patterns of Mathematics anxiety patterns were identified through statistical analysis. In addition, I confirmed that the students' interest about teachers' mathematics lessons was consistently influencing the change in mathematics anxiety. The results of this study will increase students' understanding of the formation of mathematics anxiety and can be used as basic data for the development of teaching and learning materials related to mathematics anxiety in the future and subsequent research.

Elementary textbook ${\ll}Mathematics\;4-2{\gg}$ first published in 2014 according to the 2009 elementary mathematics curriculum has been dealing with concave polygons which were not treated in elementary textbooks according to the previous curriculum. However, n the present paper, to show that there is a need to reconsider the handling of the concave polygons, after discussions about the polygon, problems in handling the concave polygons were discussed in next two viewpoints: Does 2009 elementary mathematics curriculum allow handling of the concave polygons? are there any logical leaps in handling of the concave polygon? And the following reasons to reconsider the handling of the concave polygons are presented as conclusions. First, there was no process of publicizing the handling of the concave polygon. Second, the evidences that will justify the handling of the concave polygon can not be found in 2009 elementary mathematics curriculum. Third, there are logical leaps in the handling of the concave polygons. Fourth, there is no consistency in handling the concave polygons.

The demand for private education in Korea is steadily increasing every year, and the participation rate of private education is increasing as the grade goes down. In order to empirically verify the effectiveness of private education, it is necessary to analyze through longitudinal data that has been mainly investigated over a long period of time. This study investigated the longitudinal changes in mathematics academic achievement and participation time in mathematics private education using longitudinal data from 2013 (4th grade in elementary school) to 2017 (2nd grade in middle school) of the Seoul Education Longitudinal Study. The students were divided into groups in which mathematics academic achievement changed similarly as the grade went up, and the effect of mathematics academic achievement was examined according to the change of participation time in private mathematics education for each group. As a result of the study, it was found that the participation time of private math education of all students continuously increased from the 5th grade of elementary school to the 2nd grade of middle school, and the participation time of private math education by group was different. In addition, the effect of private tutoring by group was different according to the group.

Illustrations and letters are two components of school textbooks. In the case of low grades of elementary school, textbook's illustrations play an important role in learning because many parts of curriculums(lessons) are represented by the visual forms through illustrations. So elementary mathematics textbook's illustrations have to make clear mathematical concepts and principles by visual simplification and bring out of the interest and motivation of elementary school students' learning. In this paper, we analysed the external and content aspects of textbook's illustrations, focusing on the textbook of the second grade. We investigated number, kindness, size, ratio, and clearness of illustrations in regard to external aspects. On the aspects of content, we analysed the role of illustrations and the degree of agreement with contents. Also we classified types of error in the textbook's illustrations and presented examples of errors which was found.

Since arithmetic is the foundation of school mathematics, it needs to be taught meaningfully in the direction of improving arithmetical thinking levels of students beyond the fluency of computing skills. Therefore, in this study, the arithmetical thinking levels of 100 students in 5th grade were analyzed by applying the arithmetical thinking level test. As a result, 82 students were at 1st level and 15 students were at 2nd level of the arithmetical thinking. I analyzed the characteristics of arithmetical thinking and types of errors and misconceptions made by the students, and derived some didactical implications for arithmetic education in elementary school mathematics.

The 4th grade storytelling-based mathematics textbook according to the 2009 revised curriculum was introduced in 2013. This study analyzed and investigated their perceptions regarding the storytelling teaching and learning, the effects of the introduction of storytelling, the reconstruction of storytelling, the problems and improvements of the textbook and their feelings of the storytelling lessons. For this objective, we administered the open and multiple choice surveys to fifty 4th grade teachers who had taught storytelling mathematics in 2013~2014 school years, four of them gave in-depth interviews as well. The purpose of this study is to obtain implications for the effective and reliable settlement of the storytelling teaching and learning.

The purpose of this study is to analyze teachers' understanding of the number and operations area of grades 3 to 6 in elementary school mathematics curriculum and to derive implications for improving teachers' understanding of the mathematics curriculum. To this end, elementary school teachers were asked to develop items to evaluate curriculum achievement standards at each grade level, and then the teachers' understanding of the curriculum was examined based on the collected items. As a result of the study, there was a misinterpretation of the achievement standards in approximately 25% of the questions collected. Typically, cases where the content covered by each grade was confused when using textbooks as a standard, or cases where the difference between the content covered by the two achievement standards could not be completely distinguished were found.

Story corners in elementary school mathematics practice activity books are newly given for students not only to have interests in mathematics, but to solve story problems related to already learned mathematical contents. In this study, we investigate the story corners in third grade mathematics practice activity books to analyze the contents according to their utilizations. We also suggest their implications. Based on our analysis, we have the following results. First, there are cases where the contents of the story are not related to the corresponding learning contents. Second, there are cases where some the contents or the posed problems related to the story are hard to be understood by students. Third, there are cases where the posed problems are not related to the corresponding learning contents.

In this study, an experimental elementary school mathematics textbooks in use in the effects of the storytelling investigated. For this purpose, three different elementary schools teachers and students to a group of grades 3-4 mathematics textbooks for the effects of the storytelling questionnaire study. Survey, teachers were given an overall rating of storytelling in mathematics textbooks were positive recognition. Specifically, learning motivation and communication have significant positive recognition and learning of mathematics content that was helpful. The students are given an overall rating of storytelling textbooks showed a positive reaction. Grade 3 students were more positive than the four-year students. More specifically, mathematics is interesting storytelling. That public education was more fun than private supplementary education. But for storytelling low-level math students need measures showed insignificant changes.
