The purpose of this study is to investigate the educational effects of pre-service mathematics teacher's teaching experiment on problem solving process and to give some suggestions in teacher training curriculum. The central theoretical background of this study is Palya's mathematical problem solving theory. In this study, we selected 21 pre-service mathematics teachers as research subject. And we conducted classroom activity that is constructing their problem-solving teaching design. We collected research data as observation materials, documents, video-service records etc. From these research data, we analysed that pre-service mathematics teacher's teaching experiment on problem solving process showed many significant educational effects. Therefore, we proposed that we need to serve many opportunities of teaching experiment on problem solving process to pre-service mathematics teacher in teacher training curriculum.

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.

The purpose of this research is to draw some implications for reducing gender differences in educational achievement of mathematics by inquiring those in mathematics-related attitudes. For this purpose, this article analyzed the gender difference in mathematics-related attitudes of the elementary, middle, and high school students. Also, mathematics-related attitudes according to achievement levels was analyzed. The findings of this study are as follows. Firstly, in the scores on mathematics-related attitudes, male students were significantly higher than those of female students. Secondly, in the evaluation of the subordinate factors of mathematics-related attitudes, gender differences were shown a little bit larger in the areas of interest and self confidence than in the area of perception of mathematics value regardless of grades. Thirdly, in all schools, the higher achievement level is, the higher the score of mathematics-related attitudes is. Lastly, gender differences on mathematics-related attitudes in advanced level group is bigger than those in other level groups.

In this paper, we tried to examine the didactical transpositions of the mathematical knowledges in the computer-based environment for mathematics learning and teaching, and also analyse the extreme didactical problems Computer has been regarded as an alterative that could overcome the difficulties in the teaching and learning of mathematics and many broad studies have been made to use computers in mathematics teaching and learning. But Any systematic analysis on the didactical problems of the computer-based environment for mathematics education has not been tried up to this time. In this paper, first of all, we analysed the didactical problems in the computer-based environment, and then, the mode of using computer for mathematics teaching and learning.

Variable concept plays a crucial role in understanding not only algebra itself but also school mathematics which is algebra-oriented. It solves as an essential means in applying mathematics to the real world because il enables us to describe varying phenomena in the real world. In this study, we examined some matters related to the learning of variable concept in school mathematics. In Particular, we discussed on the teaching of variable concept in the [7-first] stage of the 7th Mathematics Curriculum. We analysed the textbooks in the [7-first] stage and attempted to explain concretely the contents and teaching methods of variable concept which be taught in school mathematics. After reconsidering the practices on variable concept teaching, we pointed out the problems of formalistic teaching method and then proposed the direction in which variable concept teaching should go.

The constructivism is an important stream of the recent trends of mathematics education. In order for students to construct their knowledge for themselves, above all, it should be a prerequisite that they participate in actively, Using games helps students to participate in learning mathematics actively. I think, up to now, mathematics teachers use games mainly for motivation and it does not connect to true learning mathematics through using games. So, the purposes of this study are developing the mathematical games connecting to mathematical contents closely, designing the teaching models to connect game activities to learning mathematics, and developing several teaching plans using games to mathematics class. In this study, I propose what conditions 'good' game should have, classify games as practice game, concept learning game, and strategy game, and develop 43 games from 1 to 6 grade. And I design the teaching models depending on the game types and develop the teaching plans.

The purpose of this study is to conceptualize 'proof' school mathematics. We based on the assumption the following. (a) There are several different roles of 'proof' : verification, explanation, systematization, discovery, communication (b) Accepted criteria for the validity and rigor of a mathematical 'proof' is decided by negotiation of school mathematics community. (c) There are dynamic relations between mathematical proof and empirical theory. We need to rethink the nature of mathematical proof and give appropriate consideration to the different types of proof related to the cognitive development of the notion of proof. 'proof' in school mathematics should be conceptualized in the broader, psychological sense of justification rather than in the narrow sense of deductive, formal proof 'proof' has not been taught in elementary mathematics, traditionally, Most students have had little exposure to the ideas of proof before the geometry. However, 'proof' cannot simply be taught in a single unit. Rather, proof must be a consistent part of students' mathematical experience in all grades, in all mathematics.

This study attempts to identify the characteristics of the structure of mathematics textbooks of North Korean high schools. The previous researches on the mathematics textbooks of North Korea show that North Korean mathematics textbooks have a linear structure, which is different from a spiral structure of South Korean textbooks. However, this study found that the textbooks of North Korea published after 1994 indicate that some sections reveal a spiral structure. In addition, most sections of North Korean mathematics textbooks are collectively composed, particularly so in the section of algebra.

This study focuses on the criteria for lessons that develop secondary students' creativity and character in mathematics classes. Literature used in this study is related to the future direction of education (e.g., Core competencies, Information and Communication Technology, Constructivism education) and intent of the revised mathematics curriculum. Lesson criteria for developing students' creativity and character include educational content associated with the real-world contexts, use of tools and resources, active participation and interaction, problem-solving skills, teachers' attitudes, and the classroom environment. This study suggests ways to implement mathematics lessons that build students' creativity and character.

The graph unit(chapter) is a good example of a topic in elementary school mathematics for which computer use can be incorporated as part of the instruction. Teaching graph can be facilitated by using the graphing utilities of computers, which make it possible to observe the property of many types of graphs. This study was concerned with utilizing an educational software Graphers as an instructional tool in teaching to help young students gain a better understanding of graph concepts. For this purpose, three types of instructional activities using Graphers were shown in the paper. Graphers is a data-gathering tool for creating pictorial data chosen from several data sets. They can represent their data on a table or with six types of graphs such as Pictograph, Bar Graph, Line Graph, Circle Graph, Grid Plot and Loops. They help students to select the graph(s) which are the most appropriate for the purpose of analyzing data while comparing various types of graphs. They also let them modify or change graphs, such as adding grid lines, changing the axis scale, or adding title and labels. Eventually, students have a chance to interpret graphs meaningfully and in their own way.
