The purpose of the study was to analysis the relation between academic achievement and mathematical creativity and self-efficacy of students in specialized high school. To analysis those, academic achievement, mathematical creativity, and self-efficacy were investigated from papers. In addition, their relationship was revealed in terms of mathematics education.

The purpose of the study was to reveal teaching mathematics underachievers by application of concrete materials. For this purpose, 2 student was selected in middle school and they were interviewed after they was teaching with concrete materials by teacher in geometry field. As a result, teaching underachieve students with concrete underachieve implied efficient teaching method.

In this study, we examined the relevant parts of technical instruments for all grades in middle school mathematics textbooks that based on 2011 revised curriculum. Then we analyzed them by grade level, content areas, technical instruments types, types of teaching and learning, degree reflects the content of the curriculum. As a result, the goal of this study is to suggest a direction for how to take advantage of the technical instruments in middle school mathematics textbooks. The results of this study are as follows. First, the relevant parts of technical instruments in middle school mathematics textbooks had been concentrated in certain area, this area is a geometric area and a function area. Second, the technical instruments that is used in most of textbook were equal in each content area. Third, the teaching and learning types for the use of technical instruments were concentrated in the "inductive intended to explore", and the technical instruments were only used to guide to follow the simple steps. Fourth, it was found that in the relevant parts of technical instruments which reflects the information presented in the 2011 revised curriculum. It had been concentrated in "Understanding the principles of mathematics" and "Understanding the concepts of mathematics", but "understanding the laws of mathematics" and "problem solving ability improvement" were rare.

The purpose of the study was to investigate the math underachiever student due to individual differences and peculiarities of mathematics. Math underachiever divided into two types. Overall sluggish underachiever in all subjects, a low-alone mathematics underachievers math achievement compared to other subjects. It analyzes the features on the cognitive domain and affective domain in terms of communication in the cooperative learning of this type of mathematics underachievers. And to find a solution accordingly.
