It has already been fifty years since the Korean peninsula was divided into two nations, South and North Korea. Owing to forming different political and social structures with each other, we can conjecture that there are much heterogeneity in education. On the assumption that education plays important role in coming to an accommodation and in restoring homogeneity of the Korean race after unification, we consider the investigation of the contents of mathematics text-book of secondary schools as a meaningful research to make provision against unification. In this paper, we shall investigate the learning contents, and the learning substances and sequences in mathematics of secondary schools between South and North Korea by falling into four regions; algebra and statistics, analysis and geometry. By grasping the special features of terms, learning subject matters and learning substances, and clarifying their distinctions, we shall present some reforms measure of distinctions.

The purpose of the study was to suggest a few fundamental ideas to secondary mathematics teachers regarding using LOGO in their classrooms. Even though this software is "classic" in mathematics lessons in the States and western countries, Korean secondary mathematics teachers did not have much opportunities to become familiar with this software and its applications in their classrooms. This article offered a few suggestions with the specific guidelines. Basic commands were also listed for those who are not familiar with this software. Since the current Korean educational curriculum do not allow to use LOGO in regular classrooms as substitute lessons, it is recommended to implement these ideas in extra curriculum lessons or "Math Club" as trial basis.

The purpose of this study is to examine the mathematical creativity problem-solving ability of middle school students gifted in mathematics. For this research, we examined and analyzed the responses to two multiple solution problems of the gifted students with classifying the four categories; fluency, flexibility, originality, and elaboration which are the factors of the creativity, and comparing with responses of usual students.

This article is to advance the connection between students` achievements and meditation and to explore the direct relationship between two factors by performing meditation in class, which has not been researched. As a result of study, I am convinced that meditation has a positive relation with achievements and many further experiments and researches (This article suggested many kinds of meditation.) will surely confirm this fact.

This study has its purpose to develop an optimal teaching model in math class leading to an effective device of open education in mathematics being transformed from the current teacher-centered teaching to the individually specified student-centered one on the basis of the definitions and methods of open education learned from sundry literature references. Accordingly, this paper established several patterns of effective open math class for teaching specific math`s contents, followed by developing applicable teaching-learning models for class situation rested on each math lesson`s features. Unit learning models for open education in mathematics, which were made step by step according to each unit`s contents were also presented to be applied to real class situations.

In this paper, we analyze strategies and error patterns in solving word problems of linear equation for middle school students. From a test conducted to the sampled 106 second grade middle school students, we obtain the following results: (1) The most difficult types of word problem are velosity and density related problems. The second one is length related problems and the easist one is number related problems. (2) Regardless of the types of word problem, the most familiar strategy is the constructing algebraic equations. However, the most successful strategy is the trial and error. (3) Most likely error patterns are the use of inadequate formulas and wrong trial and errors. Based on these results, a teaching program with various schema is developed and shown to be effective for mid level students in classroom.

A multimedia CD title is developed for learning simple closed curve and Mobius band which are one of mathematics contents in the first grade of middle school. This title visualizes various figures through graphics and animations so that students can easily understand the relevant concepts and learn them with fun. It is shown that 88.6% of 30 sampled teachers are positive for the title and that 86.7% want to use it as a teaching tool in their classes.
