Russia is a country which is interested in mathematics education for gifted students for a long time. Some aspect of education for the gifted students in Russia(for example, mathematics curriculum, contents and activities of study, and selection of students in Russian physio-mathematics school) has already been studied. The purpose of this work was to introduce system of the mathematics education by correspondence for gifted students in Russia. In order to achieve this goal, we analyzed Russian literatures and articles published by the various physio-mathematics correspondence schools for gifted students. In this article, we gave some characteristics of the physio-mathematics correspondence schools for gifted students: various types of mathematics education by correspondence, curriculum, practical materials for mathematics education by correspondence.

The aim of this study is to determine a way to make mathematics textbooks after Korea is reunited. For this, the analysis of curriculum in South·North Korea must be made before unification. Therefore this study compares and analyzes the contents, organization and mathematics terms used in the latest middle school textbooks(1995-1996). And it also compared and contrasted the two textbooks while determining the best points of each. In this way, this study will be a very useful guide for making new educational curriculum and new mathematics textbooks after South and North Korea be unified.

The purpose of our work is to developing the program of math. camp to improve underachiever`s mathematical disposition. To do this, the following research were taken; (1) Analysis of current status of programs for underachievers (2) Analysis of inclination to mathematics(We collected the data from 2 classes of middle schools) (3) Prepare and apply the program of math. camp for the students including underachievers, and then analysis the effect of the math. camp The results of this study is as follows; (1) Only 40% of investigated schools have their own programs for underachivers. But almost all general high schools do not have such programs because students do not want. More than half of the investigated teachers suggested that the most important thing for underachivers is the induction of motivation for mathematics. (2) Many students dislike mathematics from 5-6 grade of elementary school, and more than 50% of students think that `measure` and `equations` items are difficult. (3) After attending the math. camp based on the games and activities in small groups, the students in the middle-ranking group showed more positive reactions against the items of mathematical disposition and attitude tests. The students in the row-ranking group were improved in the `self-confidence` and `will` items of mathematical disposition test and in the `superiority` and `interest` items of mathematical attitude test.

Ability diagnosis is similar to medical diagnosis from a number of perspectives. However, a medical diagnosis is carried out by a direct observation through medical apparatuses, while an ability diagnosis is made by an indirect observation in the form of testing. In this respect, ability diagnosis is more difficult than medical diagnosis. Confined to middle school 1st year Mathematics, we collected survey data in 1996 from monthly tests. The data consist of student responses to diagnosis results on their abilities and of the effects of catch-up guidances for individual students which are provided based on their ability diagnosis outcomes. We analyzed the data and summarized the result in the paper. One of the main results is that the ability diagnosis as used in the paper has a very positive effect on catch-up study. But it is important to note that the effects vary across the ability groups, the effect appearing weaker in the lower ability group than in the higher ability group. This calls our attention to the need that the ability diagnosis and guidance for the catch-up study be differentiated among ability groups.

The purpose of this paper is to find the role of intuition and logic in creative problem solving process. Intuition and logic have played an important role in creative problem solving process. Nevertheless, Intuition has been treated less importantly than logic. Therefore, I intend to review the role of intuition, and then the relationship of intuition and logic, and the role of intuition and logic in creative problem solving process. Although intuition gives an important clue in problem solving process, it may sometimes cause an error. This fact gives an idea that intuition and logic have to be harmoniously cultivated. In fact, Intuition and logic have been playing a complementary role in creative problem solving process. A creative learner is regarded as a mathematician of his age. It must be through intuition and logic that he/she solves the problem creatively, just as a mathematician invents the new mathematical fact through unconscious and conscious process. In this respective, teachers also should make every effort to cultivate intuition and logic themselves.

In this thesis we suggested to use the categorical data model effective to eliminate the disagreement of the experts` ratings for score adjustment and to enhance the reliability of the essay type test. The three sources of imperfection can be generally referred to as differences in severity, disagreement in merit and temporal variation. We could estimate the sizes of reliability of raters by obtaining the estimates of the inconsistency variances, σ＾_a², σ＾_b²and σ＾_c² that were results from those three sources of such imperfection. Especially to eliminate the differences in severity among many raters the randomization procedure of raters sample was very effective in enhancing the reliability of ratings with comparatively small groups of examinees and raters. And we also introduced the new rating methods, i.e. the 2-step diagnostic procedures to check the sizes of the reliability stability of raters and the sore adjustment method to enumerate the optimal mean values in rating the examinees.

This study has its purpose to diversify teaching and evaluation for college mathematics, moreover increasing students learning ability, who dislike or have lower ability to study. Cooperation, level learning and various evaluation make students better reaction in 1999 first term than in 1996 first term. Also we hope more researches for this field could be studied.

Math teachers are very short of computer tools and manipulatives to use in geometry classes of middle schools for the development of spatial abilities. At most, they can ask student to make regular polyhedrons for helping the students to understand by concrete experience, but this experience is not enough to develop spatial abilities in spatial figures including the regular polyhedrons. This article is to introduce instructional materials for development of spatial ability in the regular polyhedrons using computer software, Geometer`s Sketchpad. In this article, students can imagine the whole figure through the parts of a plane figure and think of the parts from the solid figure by free movement from 2 dimensions to 3 dimensions, or from 3 dimensions to 2 dimensions. Also, the instructional materials devised in this article will be good to enhance spatial abilities because the relation of 1-1 correspondence in the movement of the parts can be conserved and observed precisely, which is very hard to demonstrate and visualize by paper-and-pencil. It is recommended that this kind of materials should be developed in various ways for teachers to use them directly in their geometry classes.

Discrete mathematics allows students to examine and explore unique, special problem situations which were not used to solve problems by paper-and-pencil procedures or applying common formulas. The use and integration of accessible computer-related technologies such as `Mathematics` or `Maple` software programs enables students to explore problem situation dramatically. This study shows that it is possible to introduce computer-based discrete mathematics focused on the Leslie matrix model as modeling age-specific population growth to high school students.
