With advancement of computer and network, world wide web(WWW) as medium of information communication is generalized in many fields. In educational aspect, applications of WWW as alternative media for class teaching or printed matter 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 7th curriculum. This text places importance on comprehension of concepts and fundamentals of probability and statistics as applied sciences and not on simple calculations of probability and statistics.

Some discussions are made about practices which take places in some aspects of instructions from the viewpoints of traditional and reform based instruction. This kind of discussion is needed to be done, because there is no evidences to show that reform based instruction is mainly implemented among teachers even through reform based instruction has continued to be stressed since the 7th national curriculum was released. Some suggestions was made for consideration of further deep discussions based on the practices discussed earlier.

The challenge of education reform and the demand for textbook revision were inevitable as to help people manage changes in the twenty-first century. The 7th educational program not only has different educational goals, purposes and methods compare to the previous 6th program, but also introduces an epochal plan so called "free-choice learning" which involves considerable choices on the part of the learner as to what and which subject to learn. For the education on mathematics, applying computer and calculators to the studies were one of the goals educational process. This research encompasses ways to approach computer application in the 7th high school s on mathematics. The main contents of our paper are analysis of 16 different kinds of high school textbooks, its status of uses in each textbooks, math relating programs, use of computers, use of programs, use of computers in each textbooks and use of internets.internets.

The purpose of this study was to investigate the effect of STS modules reflecting Ansan's geological characteristics in Chemistry I on high school students' science related attitudes and preference for STS lessons. The subjects were 10th grade students from K High School in Ansan and comprised 71 students in the experiment group and 78 students in the control group from 2 classes each. Pretest-posttest control group design was employed for the purpose of research. Four STS modules with lesson plans and teaching materials with themes of water, air, and energy, all of which are closely related to high school Chemistry I were developed and applied to the experiment group. The science related attitudes and preference for STS lessons were then examined in pre- and post-tests. The science related attitudes of the experiment group were significantly high in three out of five domains compared to the control group who was taught traditionally. The preference for STS lessons of the experiment group were highly positive in all five areas and were particularly high in the area of 'relation to society'. Such results imply that in order to make effective high school Chemistry I curriculum units related to STS, emphasized by both the 7th National Curriculum and the Revised 7th National Curriculum, it is necessary to use episodes reflecting local characteristics in which students show greater interest and active participation.

As a theoretical background for this research, the literatures which focus on teaching and loaming of connecting with mathematics and science were investigated. And the rationale of integrated curriculum on the basis of the 7th mathematics curriculum and the goal of mathematics education and the forms of integrated curriculum and the integrated curriculum in foreign school were investigated. Depending on this review, the implement method of the integrated curriculum of mathematics and science in Korea school is suggested as the following: It requires designing inter-disciplinary into-grated problem or various teaching and learning materials which are based upon concept, skill, and principle by commonality found across the subject matter. Based on the analyses upon described above, three inter-disciplinary integrated teaching and learning materials were developed. And then, based on the case stud)', the research questions were analyzed in depth. Students could understand the developing process of linear function, develop the formula and grape representing the relationship between time and velocity, time and distance, and interpret realistic meaning of the slope.

The purpose of this study is to develop and implement an alternative elementary science curriculum to enhance creative problem solving abilities. The curriculum consisting of three main elements was developed. The three elements are content knowledge, process knowledge and creative thinking skills. The curriculum was validated by more than 10 science educators, scientists, and curriculum specialists. In order to implement the curriculum, three lessons for 5th grade were developed and taught by a problem-based-learning(PBL) method in an experimental group during the second semester. For the comparison group the ordinary lesson based on the 6th national science curriculum was taught by the same science teacher during the same period. Performance assessment was developed and used for the pre and post test. Two-way ANOVA, and T-test were used to check whether there are any significant differences between the gains of scores(pre-post test) of the two groups. The results of the test showed that the experimental group increased significantly in the total creative thinking problem solving skills, but the comparision group did not.

The purpose of this study was to compare the illustrations used in elementary science textbooks of Korea and BSCS in USA, and analyze the types, role, and characteristics of the illustrations. For the analysis, we used 8 elementary science textbooks of the 7th curriculum of science education in Korea from 3rd through 6th grade, and 16 volumes (stage 2 to stage 5) used in BSCS in USA. We examined types of illustrations, including photograph, picture, graphic, cartoon, chart, and their 4 roles such as, motivation, introducing the lesson activity, providing the materials, presenting the learning result. The results were as follows: First, Korean textbooks have more "photograph" type of illustration than BSCS. In BSCS textbooks, diverse types of illustrations were used compared to Korean textbooks. Second, large portion of illustrations in Korean textbooks took a role of providing materials. In BSCS textbooks, the roles of illustrations were more diverse. In BSCS, there were many illustrations to describe students working together with the disabled children, and to explicitly encourage cooperative learning. Considering the findings in this study, educational implications were discussed.

To examine the effect of students' Cognitive level upon their achievement on Science. the students' cognitive levels were tested by using GALT(Group Assessment of Logical Thinking) and examined the Correlation between the cognitive level and achievement According to the results, most students were still in the conerete level. Only 60% of 9th grade students could handle the logic of displacement volume. In case of proportional logic and logic of probability, only 40% of 9th graders could handle them. Only 10% of the students could understand Correlational logic. Cognitive level and students achievement were estimated to be in a very closely related. Students who were in a high cognitive level showed better achievement scores on knowledge, comprehensive, inquiry, and application items than those who were in low cognitive level. Therefore, this study suggests that the content of the current middle school science should be revised in away to match the students' cognitive level.

The era of the Fourth Industrial Revolution calls for creativity - convergence talent. In addition to having mathematical knowledge, they can create new technologies by linking them to other fields. This social trend is also reflected in the 2015 revised curriculum, and plans to further expand the STEAM education emphasized since 2011. Many teachers who had previous experience with STEAM training were satisfied with the STEAM teaching effectiveness. However, the reality is that the lack of expertise in other subjects is causing a burden on the ongoing implementation of convergence education. One way to alleviate these teachers' burden is to find the STEAM elements and then apply. Since the convergence education is required continuously, it is necessary to analyze the textbook according to the 2015 curriculum. In this study, we examined how the elements of the STEAM were apply in 7th grade textbooks. Based on the classification framework proposed by Yakman (2008), a new classification framework was devised and applied to the analysis.

In this paper, a highly effective learning model that can be applied to the 7th level-based curriculum, which will begin in high schools in the year 2002, will be proposed. Two learning models that have different perspectives on dividing the students into level groups(diagnostic evaluation model and formative evaluation model) were introduced, and teaching materials for each model were developed. After applying the teaching materials to actual classes, the achievement rate of the students was analyzed. According to the results of this research, the achievement rate of students is affected by the point of time at which they are divided into level groups, and formative evaluation proved to be the superior learning model dividing students into level groups.
