The purpose of this study is to investigate the mathematical disposition and mathematical communication level of elementary school students in the process of applying mathematical journal writing activities. For this study, 21 third grade students in elementary school were observed when they participated in mathematical journal writing activities while studying number and operation area. According to the Mathematical disposition pre-test and post-test results, mathematical confidence, mathematical flexibility, mathematical will, and mathematical reflection increased and it was statistically proved. Expression and explanation level of the mathematical communication writing area also increased as the mathematical journal writing activity continued. Thus, mathematical journal writing activities can help to enhance the core competencies of the 2015 revised mathematics curriculum while make students 'to develop and transform mathematical expressions' and 'to express oneself'. Also, it provides implications of including active writing activities such as mathematical journal writing activities into mathematics classroom. Furthermore, the change in mathematical communication level according to mathematical disposition level was not statistically significant. Therefore, when providing active writing activities including mathematical journal writing activities into classroom, it is necessary to understand students' individual characteristics and to encourage communication to be active rather than giving feedback based on one's mathematical disposition level.

This study was conducted to examine the effects of mathematical activities with online mathematical contents on children's arithmetic development and attitudes toward mathematical activities. Pre- and post-tests were administered to 62 5-year-old children. Differences of children's arithmetic development level and attitudes toward mathematical activities were found between the experimental group using online mathematical contents and the control group using offline mathematical contents. All findings proved that online mathematical contents were effective and had positive influences on children's arithmetic development and attitudes toward mathematical activities. This supports the proposition that online mathematical contents can provide an important means to the improvement of children's mathematical development and attitudes toward mathematical activities.

본 연구는 고등학교 2학년 학생을 대상으로 수학일지 쓰기가 수학적 태도에 어떠한 영향을 주는가를 알아보는 데 있다. 실제로 수학일지 쓰기를 통해 고등학생들은 성취감을 느끼고 반성적 사고를 하게 되며, 수학적 이해과정에 도움을 받는 것으로 나타났다. 또한 수학일지 쓰기가 학생들의 학습태도를 긍정적으로 바꾸며 수업에 적극적으로 참여하게 하였다. 반면 자신의 생각이 노출되는 것에 대한 부담을 느끼는 것으로 나타났다.

In recent years, the term core literacy has been popular in educational circles all over the world, and there are more and more research on core literacy. At the same time, the mathematical culture has also been highly valued on a global scale. The mathematical culture is a part of college students' cultural quality, and then, what is the connection between the mathematical culture and mathematical core literacy? How to improve the mathematical core literacy of contemporary college students? This paper gives the corresponding answers to these two questions. By illustrating the concrete implementation of the course "Mathematical Culture" offered by Yanbian University, this paper discusses various measures for cultivating students' core qualities in Chinese universities. It must be useful and promote the research on mathematical core literacy for the educators in various countries.

The purpose of this study was to examine the factors influencing their mathematical learning abilities and mathematical learning potential in an attempt to assist their learning at the preschool level. The findings of the study were as follows : First. the female children performed at a much higher level than their male counterparts in terms of mathematical learning ability and mathematical learning potential training. The young children generally improved in their mathematical learning abilities and mathematical learning potential with age. Second, it was found that the participants had higher levels of both mathematical learning ability and mathematical learning potential when their mathematical attitudes and learning motivation were better. Third, there were significant differences in terms training-test and transfer-test scores between the 4 groups based on their relative levels of mathematical abilities and attitudes.

The purpose of this paper is to reconsider the meaning of mathematical literacy based on the investigation of the nature of mathematical knowledge communicated in university level mathematics classes. The analysis of classroom discourse has revealed three different kinds of mathematical knowledge circulated in mathematics class, which include 'factual mathematics', 'mathematical fantasy', and 'mathematical savior faire.' The fact that a mathematics teacher delivers diverse categories of mathematics knowledge suggests that the mathematical literacy is not confined to the development of technical competence. More specifically, the kinds of mathematical knowledge identified above tell that mathematical literacy developed through learning mathematics reflects the cultural norms and values of doing mathematics. This means that mathematical literacy is not merely involve with technical competence but rather with cultural competence. In this regard, this paper highlights the meaning of mathematical literacy as a cultural identity, which has been underestimated in the theory and practice of mathematics education dominated by technocracy of the twentieth century In particular, the notion of mathematical savior faire implies that teaching and teaming mathematics ultimately deals with a system of cultural meaning. Hence, through learning mathematics, a learner gets transformed as a whole person according to the cultural norms and values. In this regard, it is concluded that mathematical literacy can be considered as a necessary condition to become a competent member of mathematics community sharing cultural norms of doing mathematics as well as a repertoire of mathematical skills.

This study was planned to investigate the effects of mathematical games with motion on young children's development. The study was performed to compose mathematical games with motion and just mathematical games for young children. The games were set up to be executed 16 times for 8 weeks. The results of this study were as follows: Mathematical games with motion had a significant effect on young children's mathematical problem-solving ability. Mathematical games with motion had a significant effect in every category on young children's ability for motion competence and mathematical games with motion had a significant effect on young children's socio-emotional development. There were significant differences between the control group and the experimental group except for the independence from teachers and peer interaction. Mathematical games with motion had a significant effect on young children's language ability.

The flexible mathematical thinking - the ability to generate and connect various representations of concepts - is useful in understanding mathematical structure and variation in problem solving. In particular, the flexible mathematical thinking with the inventive mathematical thinking, the original mathematical problem solving ability and the mathematical invention is a core concept, which must be emphasized in all branches of mathematical education. In this paper, the author considered a case of flexible mathematical thinking with an inventive problem solving ability shown by his student via real analysis courses. The case is on the proofs of the equivalences of three different definitions on the concept of limit superior shown in three different real analysis books. Proving the equivalences of the three definitions, the student tried to keep the flexible mathematical thinking steadily.
