In relation to differentiated mathematics education, Russia has a longer experience in research and practice than Korea. The mathematics curriculum for 10-11 grades currently in use in Russia is a level-specific curriculum and consists of a basic level and an advanced level. And in Russia mathematics textbooks for 10-11 grades are also textbooks for each level. In this study, we analyzed basic level textbook and advanced level textbook written by the same author group among the textbooks 'Algebra and Introduction of Mathematical Analysis' of the 10th grade in Russia. To analyze the main learning contents and textbook descriptions that were added in advanced level the 'real numbers' and 'complex numbers' sections were studied. The main contents of basic and advanced level textbooks for 'functions', 'trigonometric functions', 'trigonometric equations', 'conversions of trigonometric expressions', and 'derivatives', which are included in both basic and advanced textbooks were compared and analyzed, and the descriptive characteristics of the definitions and theorems presented in the two levels of textbooks were also compared and analyzed. From the results of this study, it is expected that various information on the contents of various level textbooks of mathematics, the differences between textbooks for each level, and strategies for the composition of textbooks for various level can be accumulated.

The purpose of this study was to examine the effects of the level-differentiated laboratory activities suggested by the 7th national curricula compared to the in-depth level activities only and supplementary level activities only. Two hundred 7th grade students attending a coed middle school were selected for this study and divided into three groups; level-differentiated, in-depth, and supplementary group. In each group, the students were subdivided into the in-depth level and the supplementary level by the formative test after completing the basic learning course. The in-depth and the supplementary laboratory activities were developed and engaged to the respective students in the level-differentiated group for one semester, while only the in-depth activities were engaged to the in-depth group and only the supplementary activities were engaged to the supplementary group. To examine the effects of treatments, the science knowledge test and the inquiry process skill test were administered before and after treatments and the students' opinions about the level-differentiated instruction were surveyed. The results showed that there were significant differences in the science knowledge achievements between the groups while no significant difference was found in the inquiry process skills. Post hoc analysis showed these differences were found between the level-differentiated group and the supplementary group. After the activities, most students in the level-differentiated group responded positively on doing level-differentiated activities except a few students in the supplementary level, These results justify the effectiveness of the level-differentiated laboratory activities compared to the supplementary only laboratory activities in middle school science classes.

We've run leveled intense and supplementary study groups connected with JAVA regular classes for more effective learning of computer programming. We performed the test for evaluating learning understanding degrees between before and after study to analyze learning effect for three leveled study groups and a non study group, and we also analyzed the differences of learning understanding degrees among 4 learner groups by computer programming areas. As a result, we can reach the result what programming areas are effective to be operated by intense and supplementary study groups. Those areas are the area to improve the ability of programming applying concepts through in-depth understanding of concepts, and the area of programming through mixed knowledges related each other. The study group for low-leveled learners has most improved of four groups. Low-leveled group was behind the other study groups on programming application ability, but the group was more excellent than non study group in most programming areas.

The purposes of this study are to investigate the school science high achievers' achievements in enrichment physics, logical thinking level, and to analyze the relationship between logical thinking level and the achievement in enrichment physics of high achievers in science. The subjects were 357th and 8th graders who achieved highly in school science. To assess their achievements in enrichment physics, we developed a new test consisting of descriptive problems which were based on middle school curriculum. Those problems require one or two steps of thinking process, not simple knowledge of science. To assess logical thinking level, we used the instrument called GALT(Group Assessment of Logical Thinking) developed by Roadranka et al. The results showed that the school science high achievers' average achievement in enrichment physics was low, 56.3 out of 150, which indicated that they had not done much of enrichment learning beyond middle school science curriculum. Just only 54% of the school science high achievers are in formal logical thinking level. From the analysis of relationship between their logical thinking level and the achievement in enrichment physics, the value of the correlation coefficient was 0.174, which means that they are not almost correlated. Therefore, it is not desirable to judge science gifted children just from achievement in school science or enrichment physics, so both(logical thinking and the achievement in enrichment physics) tests should be taken for selecting gifted student.

The purpose of this study is to analyze the actual realization of the opportunity to learn given to students by examining students' cognition for enrichment mathematics textbook tasks' levels of cognitive demand. First, we analyze characteristics and limitations based on the theoretical framework. Second, we examine students' cognition about the distribution of the mathematics textbook tasks' levels of cognitive demand. And we analyze how the opportunity to learn actually work. Third, in the sense that enrichment textbooks are textbooks for science school students, we analyze whether the opportunity to learn for gifted is offered. The conclusion is as follows: First, with respect to levels of cognitive demand, PNC tasks account most. Second, students also cognize that PNC tasks account most. Third, tasks for gifted are not offered and students also cognize that opportunity to learn for gifted is lacked.

The purpose of this study was to examine the effects of the application time of differentiated instruction in terms of learners' science academic knowledge achievement and their attitudes toward science. The findings of the study were as follows: First, the experimental group was significantly higher than the control group (p<.05). Second, the academic knowledge achievement of high ability students of two subgroups was not different (p>.05), but the achievement of low ability students was higher in experimental group than in control group (p<.05). Third, the experimental group showed higher improvement in attitude toward science than the control group in three areas of the Test of Science Related Attitudes (TOSRA) (p<.05): 'Adaptation of Scientific Attitudes', 'Enjoyment of Science Lessons', and 'Career Interest in Science'. However, there was no significant difference between the experimental and control groups in the area of 'Attitude to Scientific Inquiry' and 'Leisure Interest in Science'.

This study aims to describe the status quo of the social studies curriculum of universities of education in Korea, to extract the questions at issue, and to suggest new directions for improvement. To approach these purposes, the author grasps the viewpoints that the intensifying course of the department of social studies is investigated with relation not only to the national curriculum on elementary social studies but also to both specialization course and liberal arts course. Intensifying course have been organized to strengthen the teaching-teaming abilities on the subject matter contents since the beginning. But the present day, intensifying course meets several problems waiting solution: problems in reference to overlap with specialization course, to disconnection with liberal arts course, and to the internal disequilibrium. So, the author proposes six solutions for the problems.

The basic tenet of science education by the 7th national curriculum for middle school students is teaching by learner's academic levels. It is a kind of new approach to both of teachers and students, but there has been little preparation in school fields for the new approach. Therefore, this study reviewed the characteristics and constraints of the approach, and suggested the types of learning methods for the approach. And then this study explored the guidelines for writing a lesson plan for the science education by the 7th national curriculum. Specifically, this study presented an example of lesson plan for a unit of middle school chemistry.
