The purpose of this study was to analyze the current implementation states of the differentiated curriculum at the middle school and to propose ways to improve it. For that purpose this study conducted a survey and had the interviews with the middle school mathematics teachers. The items of survey and interviews consisted of the two main parts: current states and needs about the special supplementary courses and enriched supplementary courses. The results showed that there were discrepancies between the current states and the needs of the differentiated curriculum. This means the efforts to improve the current states are needed. The strategies for improving the implementation of the differentiated curriculum are as follows: 1. The use of various standards including the subject-achievement level and students' or parents' opinions is needed in selecting the students of special supplementary course. 2. More relevant special supplementary materials need to be developed and utilized. 3. The ability grouping is recommended for the differentiated instruction. 4. The deliberation of developing the enriched and supplementary texts is requested. 5. The study for differentiated evaluation of students is demanded.

The purpose of this paper is to improve the curriculum efficiently and to raise the level of students's satisfaction by studying the correlation between MSC and major courses. For this, we compared the student's grades for those courses. Furthermore the level of satisfaction of the MSC subjects was surveyed. We found that one of dissatisfactions was due to the student's low recognition about the Accredited Program. So efforts to raise the student's satisfaction abouts the program should be done continuously and an in-depth study about MSC and major courses is necessary instead of just offering the required subjects.

In the era of wireless internet, we are apt to use a mobile phone for learning mathematics, besides the pc computer and the notebook computer. This study was to investigate the effect of M-learning when students were given a wireless mobile phone in terms of their perspectives towards the use of a mobile phone, achievement and attitudes towards mathematics. They were the 3th grader in a high school, who were expected to take Aptitude Test for the entrance of the university level. The most students who took an ubiquitous environment of M-learning showed it as a benefit for learning mathematics and did not spend time at other activities such as listening to music, sending text-message, playing games, etc, but at the M-learning activities. The students who engaged in the M-learning activities were improved a significantly higher score at Aptitude Test than the students who took the make-up courses in the school and also did a significantly higher disposition towards mathematics which was caused by curiosity among 7 components of the mathematical disposition.

The purpose of this study is to analyze the effects of parental educational involvement and mathematical attitude perceived by students on math motivation and math anxiety. The results showed that parents' educational involvement had effect on students' motivation to learn mathematics and had a significant effect on mathematics anxiety. In addition, the parents 'mathematical attitude has a significant effect on the motivation of the students, and the higher the mathematical attitude of the parents, the lower the mathematics anxiety of the students but the higher the students' mathematics anxiety. This suggests that even if the parents are educated, the parents can influence their motivation to learn mathematics, rather the more the achievement pressure becomes, the higher the educational involvement. In addition, the parents' mathematical attitude is independent of the degree of educational involvement, and parents can expect to increase their motivation to learn mathematics by nurturing with positive and positive perceptions and attitudes. In order to do this, it is a time when parents' education for the recognition of parents' right mathematics courses and their interest in education and the role of education are positively required.

With the importance and necessity of using AI in the field of education, this study aims to explore elementary school teachers' perceptions of using Artificial Intelligence (AI) in mathematics education. For this purpose, we conducted a survey using a 5-point Likert scale with 161 elementary school teachers and analyzed their perceptions of mathematics education with AI via four categories (i.e., Attitude of using AI, AI for teaching mathematics, AI for learning mathematics, and AI for assessing mathematics performance). As a result, elementary school teachers displayed positive perceptions of the usefulness of AI applications to teaching, learning, and assessment of mathematics. Specifically, they strongly agreed that AI could assist personalized teaching and learning, supplement prerequisite learning, and analyze the results of assessment. They also agreed that AI in mathematics education would not replace the teacher's role. The results of this study also showed that the teachers exhibited diverse perceptions ranging from negative to neutral to positive. The teachers reported that they were less confident and prepared to teach mathematics using AI, with significant differences in their perceptions depending on whether they enacted mathematics lessons with AI or received professional training courses related to AI. We discuss the implications for the role of teachers and pedagogical supports to effectively utilize AI in mathematics education.

In this paper, we consider a center of gravity of convex polygon which could be an enriched topic for the gifted in mathematics(7th grades) and suggested a case that the gifted experienced a center of gravity. Based on properties of Archimedes' center of mass, we define it as a point which make a polygon be in counterpoised with its area and explain how to find that point through using integral calculus or internal division. Then we consider that the gifted would experience various kinds of mathematical thinking and apply diverse ways of problem solving 3s searching for this topic. As this research, the teacher would be able to conduct the gifted with penetration into center of gravity and to let them participate in advanced learning courses which value ma-thematical thinking while they undergo similar experiences such as mathematicians.

Taking samples of data and using samples to make inferences about unknown populations are at the core of statistical investigations. So, an understanding of the nature of sample as statistical thinking is involved in the area of statistical literacy, since the process of a statistical investigation can turn out to be totally useless if we don't appreciate the part sampling plays. However, the conception of sampling is a scheme of interrelated ideas entailing many statistical notions such as repeatability, representativeness, randomness, variability, and distribution. This complexity makes many people, teachers as well as students, reason about statistical inference relying on their incorrect intuitions without understanding sample comprehensively. Some research investigated how the concept of a sample is understood by not only students but also teachers or preservice teachers, but we want to identify preservice secondary mathematics teachers' understanding of sample as the statistical literacy by a qualitative analysis. We designed four items which asked preservice teachers to write their understanding for sampling tasks including representativeness and variability. Then, we categorized the similar responses and compared these categories with Watson's statistical literacy hierarchy. As a result, many preservice teachers turned out to be lie in the low level of statistical literacy as they ignore contexts and critical thinking, expecially about sampling variability rather than sample representativeness. Moreover, the experience of taking statistics courses in university did not seem to make a contribution to development of their statistical literacy. These findings should be considered when design preservice teacher education program to promote statistics education.

Linear system is a basic subject matter of school mathematics courses. Even though elimination is a useful method to solve linear systems, its fundamental principles were not discussed pedagogically. The purpose of this study is to help the development of mathematical content knowledge on linear systems conceptions. To do this, various representations and translations among them were considered, and in particular, the basic principles for elimination method are analyzed geometrically. Rectangular representation is used to solve word problem treated in numbers of things in elementary mathematics and it is useful as a pre-stage to introduce elimination. Slopes and intercepts of lines associated linear equations are used to obtain the Cramer's formula and this solving method was showing the connection between algebraic and geometric procedures. Strategy deleting variables of linear systems by elementary operations is explored and associated with the movements of lines in the family of lines passing through a fixed point. The development of mathematical content knowledge is expected to enhance pedagogical content knowledges.
