This paper has analyzed the problem of the inequality unit in 7th National curriculum 8-Ga stage from the following points. First, in respect to the written questions of the inequality unit over every textbook of 7th National curriculum, how are they allocated according to subject matters and what are their weak points? Second. how many of them are related to the authentic daily life or other subjects and what kind of subjects are they? Third, what are the problems related to the authentic daily life situation or what are the problems that have some inter-sentential errors, and what kinds of measures for their improvement can be taken? In keeping with view points above, we have analyzed the contents in current 16 different textbooks on th basis of their subject matters and especially put the emphasis on the relation to daily life and other subjects. Consequently, we found there are many textbooks that do not include various subject matters and that can not be related to various other subjects. It is necessary to connect mathematics to various daily life matters and other subjects to improve students' creativity and to make students understand the practicality of mathematics.

Recently, for solving a math problem, and I reflect back, so much emphasis on activities which reflect the activities conducted in schools is necessary to look for. In this study, the 7th Mathematics Curriculum textbooks (10 - a, b) and 7th in mathematics and modification of curriculum textbooks (math) in the reflection type of activities that explore the resulting problems and the measures we discuss are. Therefore, textbooks reflect the type of activities were analyzed before and thinking strategies, and we will examine various types of reflective activities.

As an attempt to systematize environmental education in the 7th curriculum, this study extracted the contents of environmental education to which science can approach in the science lessons. This study analyzed these contents from the goals of environmental education and from its contents and, as a result, it found out the followings : (1) in the aspect of ‘knowledge’ and ‘skills’, the goals of Science environmental education have direct relations with each other, and (2) the science can be taught in the aspect of ‘natural environment’, ‘environmental ethics’, ‘environmental pollution’, ‘resources’, and so on. By utilizing various teaching and learning methods of science education the science subject on, however, approach the goals of environmental education, of ‘attitudes’ and ‘participation’.

Now, mathematics textbook is being developed in accordance with the 7th educational curriculum. It is expected that qualified textbook reflecting 'differentiated education' concept be developed and published. But there are still many limitations of textbook authorization system to develop 'such' textbook. Many authors of textbook have difficulty in developing creative and qualified textbooks in their own way. In this paper, we deal with what the authors should keep in mind and could reflect related on textbook authorization system in developing textbook. For this purpose, focusing on new 'content principle' of mathematics textbook authorization, the paper presented its educational background.

The purpose of this study is to survey the status of the 7th elective-centered curriculum and find problems in operating the system. 485 students in the tenth and eleventh grade were randomly selected as subjects. The results are as follows. (1) Among the students, 29% of them selected their science subject without considering their future jobs, 48% did it without enough overview of the system, and 25% did without clearly understanding the details the choice centered curriculum. (2) Among the students who participated in the survey, 65% of them showed positive responses concerning the needs of individual choice centered curriculum and 96% said it increased their participation in class. However, only 39% believed that operating this type of curriculum is realistically possible. (3) 89% of students selected their science subjects accordingly with the college preparatory courses and 14% selected based on their hopes. (4) The percentage of science subjects chosen are 40% for chemistry, 25% for biology, 22% for Physics, and 13% for earth science, but 74% of students wanted to change their choices. These results showed that students recognized the object of the 7th curriculum, but selected science subjects as a means of getting into college entrances, rather than carefully considering their future and aptitude.

This study was composed of series of guidance contents in the sub-field of spatial sense from the 7th curriculum according to the series theory by the level by Gagne & Briggs. As for the guidance contents in this field, this study discovered that it had ‘experiencing the various space senses’,‘operating it mentally (internalization)’, and ‘utilizing and expressing the space sense mathematically’ in order largely. The contents of series constitution by the subject and by the stage, a result of this research, will be helpful to the establishment of achievement standard and valuation standard by the stage.

With advancement of computer and network, world wide web(WWW) as a medium of information communication is generalized in many fields. In educational aspect, applications of WWW as alternative media for class teachings or printed matters are increasing. In this article, we demonstrate a web-based electronic text on the 'probability and statistics' which is one of six fields of mathematics in the 7th curriculum. This text places importance on comprehension of concepts of probability and statistics as an applied science.

The goals of this study is to analyze develop the materials which help students develop spatial sense in elementary school and to investigate its effects. To accomplish those goals, the 7th National Curriculum was analyzed to identify the contents of spatial sense. After analyzing the 7th National Curriculum, the principle for developing the teaching aids focusing the realization of the contents in the spatial sense was set up. And then various teaching materials which can enhance students' spatial sense was developed. It is consist of 17 kinds of concretely operating materials, 7 kinds of tangram papers, one web-material. To verify the effect of the materials, surveyed the usability of the materials and two classes was selected and tests were administered before and after the treatment. Through this application, several conclusion were drawn. First, a survey result says that teachers thought materials developed would be effective in developing spatial sense. Second, the materials developed were effective to develop spatial sense. The score gained by the experiment group after the treatment was statistically meaningfully higher than the control group. This means that the materials developed helped children to develop spatial sense.

One of the biggest changes in the 2015 revised mathematics curriculum is shifting to the second year of middle school in Pythagorean theorem. In this study, the following subjects were studied. First, Pythagoras theorem analyzed the expected problems caused by the shift to the second year middle school. Secondly, we have researched the reconstruction method to solve these problems. The results of this study are as follows. First, there are many different ways to deal with Pythagorean theorem in many countries around the world. In most countries, it was dealt with in 7th grade, but Japan was dealing with 9th grade, and the United States was dealing with 7th, 8th and 9th grade. Second, we derived meaningful implications for the curriculum of Korea from various cases of various countries. The first implication is that the Pythagorean theorem is a content element that can be learned anywhere in the 7th, 8th, and 9th grade. Second, there is one prerequisite before learning Pythagorean theorem, which is learning about the square root. Third, the square roots must be learned before learning Pythagorean theorem. Optimal positions are to be placed in the eighth grade 'rational and cyclic minority' unit. Third, Pythagorean theorem itself is important, but its use is more important. The achievement criteria for the use of Pythagorean theorem should not be erased. In the 9th grade 'Numbers and Calculations' unit, after learning arithmetic calculations including square roots, we propose to reconstruct the square root and the utilization subfields of Pythagorean theorem.
