Students' emotional attitude not only affects their achievement in a meaningful way but also is an important educational goal in its own right. This research investigated how students' interest in science varies among elementary, middle and high-school students based on a survey and reviews of previous research results. We analyzed students learning attitude in terms of interest in and enjoyment of science, instrumental motivation in science, science learning anxiety, and self-concept in science. Major findings are students showed more negative attitudes in intrinsic motivation, instrumental motivation, value perception of science, and confidence in science as they move in to a higher school level. According to students' explanation, science classes got bored in a higher grade because of difficult contents, lack of experiments and activities, and teachers' monotonous explanations. Based on the results, recommendations on how to improve students' attitudes towards science are suggested. First of all we need to secure more science instructional hours in the school curriculum than the 7th national curriculum to implement improved science teaching and learning methods.

The purpose of this research is to analyse the composition of theories and practical activities in clothing and textiles in Technologyㆍ Home economics textbooks in the 7th National Curriculum and find out learning requirement of students in the area. For this research, a survey was conducted using questionnaires with 280 high school students living in Daegu and the rate of response was 78.9%. The results of this study are as follows. 1. After analysing the curriculum of Practical Arts subject in elementary school and Technology´ Home Economics subject in secondary school, we could find out that more emphasis is put on practical activities in elementary school and high school. On the other hand, theories are considered more important in middle school. 2. Students have similar preference both for theories and for practical activities as a way of learning in class and show positive responses to practical activities unless they´re giving too much pressure as a part of performance test. 3. According to their learning requirement. several teaching-learning contents in clothing and textiles in Technology Home economics are selected such as materials,. clothes designs, how to set dressed well, how to make a reasonable purchase on clothes, and the process of manufacturing various clothes, etc. Therefore it would be desirable to provide the students with the learning opportunity to the extent where even the students who haven´t chosen the selected-advanced course can take part in class actively.

Currently science and technology are changing so fast and college mathematics becomes more and more important. But the downturn of freshmen's scholastic performance has been intensified and this phenomenon leads to serious problems in managing college curriculums. During the recent years at a middle level engineering college, many freshmen had a lot of difficulties in their mathematics courses. In consequence, many of them had hard time to survive at their major curriculums. In this point of view, we analyse the situation of mathematical scholastic ability among engineering majored freshmen through the research on the actual state of mathematical background, mathematical scholastic ability test, college mathematics scores, and scholastic aptitude test scores. We study the relation between the mathematics score of scholastic aptitude test for the college entrance and mathematical scholastic ability of freshmen of a middle level engineering college. From this study we conclude that the essential reasons for the above situations are the curriculum of middle school mathematics and the system of scholastic aptitude test and the entrance examination of university. In order for improving mathematical accomplishment. we give suggestions such as a learning ability improvement program in mathematics.

The purpose of this study is to improve the experiment of dihydrogen production which was newly added to the 7th curriculum of the elementary science education. For this study, the teachers who had taught 6th grade students were asked about the difficulties they ever had in the dihydrogen production experiment by questionnaire. And the contents of the science textbook and teachers' guide book were analyzed. According to this investigation, the following controversial points were found. First, they didn't have exact explanations about the concentration of hydrochloric acid and the quantity of hydrochloric acid and magnesium in the science textbook and teachers' guide book. Second, the experiment which can show well the nature of dihydrogen was not included because of the safety problem. So this paper presents the ideal condition for the production of dihydrogen and an experimental method to show the nature of dihydrogen. The most ideal condition of dihydrogen production includes 40 mL of 2 molarity hydrochloric acid and 1 g of magnesium. It took 5' 42＆apos; on average to gather two bottles (250 mL) of dihydrogen. In this condition it was possible to reduce the risk of accidents and to economize the materials. This paper proposes the experiment of dihydrogen explosion with a test tube and a film box which is not included in the 7th scince textbook. If teachers show the experiment of dihydrogen explosion with a test tube or film box to students at a class, it will be more interesting for students. And they will be able to help students to understand that dihydrogen can be gathered.

The purpose of this study was to analyze hierarchy for high school students' concepts about genetics. The assessment of genetics related concept was conducted for 10th and 11th grade students and a hierarchy map was schematized based on the evaluation result using Knowledge State Analysis Method. Some differences were found when comparing the result of whole students' hierarchy with hierarchy on 7th national science education curriculum. In analyzing hierarchy by grade, concepts of highest and lowest level turned out same but some concepts of middle level changed. In case of analysis of hierarchy for concepts about genetics by score, as score was higher, the number of concept in lower level became larger and the relationship among concepts became more structurized. Following studies are required to develop specific teaching strategies for having effective genetics concept and conduct case study of applying the concept hierarchy through this method to class in the field.

The expansion of open education and the 7th revision of educational curriculum have brought big changes in the school facilities. In response to the integrated curriculum for the first and second grades of elementary school, various plans, such as open classroom, expanded classroom size, and the installation of multi-purpose space, have been attempted. However, such plans have appeared in the form of an open classroom--a uniform spatial composition. As a result, a plan for unit learning space to support the educational curriculum and activities for low grade levels is still insufficient. In the case of advanced countries, a lot of studies on space are being actively conducted to develop the creativity of children and to facilitate free-style learning, and such space is actually applied to a real educational environment. Therefore, this study will analyze the spatial composition of unit learning space for low grade level elementary schools in Korea. From the cases of advanced countries, a more concrete proposal will be suggested to diversify unit learning space for low grade levels.

The purpose of this paper is to find out the full extent of abilities of elementary students on area of operations and the effects on student's affective domain toward mathematics, after providing 3rd grade students with Skemp's play activities instead of providing activities suggested in the textbook of 7th curriculum. For this study, we will first analyse new elementary mathematics curriculum of 3rd grade and then explore mathematical factors for play activities related to operational sections. The play activities are revised from that of Skemp's for our classroom circumstances, but the ideas included from Skemp's such as thinking aloud were not changed. The experimental group while consists of 39 students were taught Skemp's play activities instead of usual textbook activities for 30 hours for the second term. In all other area, both the experimental group and the comparative group were taught the same contents. Statistical data is as follows 1) In addition and subtraction, the experimental group had 5.6% higher score than the comparative's, but the difference of mean of the both groups is not significant within 5% level. 2) In multiplication and division, the experimental group had 7.8% higher score than the comparative's and also the difference of mean of the beth within 5% level is significant. 3) When measured the effects in affective domain, the interests, attitude, and values for mathematics had about 10% higher score after the experiment than before the experiment. So we conclude that Skemp's activities are more effective than the activities suggested in the textbook on the area of operations, especially in multiplication and division.

In this study, the models described in the textbooks related to floating and sinking phenomena in the chemical domain were evaluated based on the aspect of nature related to the generation of models. To achieve this, we were targeting statement of textbooks from 7th curriculum to 2009 revised curriculum. Analysis of textbooks was performed for science of elementary school (total 2 textbooks) and science of middle school (total 21 textbooks) which dealt with these phenomena. According to the textbooks analysis, characteristics of statement way were (1) No description of the model's prerequisites, (2) Statement based matter viewpoint, (3) Lack of pattern principle, (4) Inadequacy of the case covered. Although the education about the model for the students should be preceded by the education related to the process of model creation rather than the activity using the model, the education about the nature of the model is insufficient. In order to solve this problem, we propose the model statement in textbooks and the development of the model evaluation tool related to model creation.

In this research we diagnosed the actual status of the 7th National science elective curriculum and suggested a way to select and organize the content of the new science elective curriculum. The first science education reform was grounded in the structuralism where the structure of discipline was valued above everything else. On the other hand, the second science education reform suggested alternative interpretations of students' opportunity to learn, putting a brake on the structuralist thinking. According to the survey result, the majority of the science elective courses are in need for revision because the contents are overcrowded, too difficult in light of students' learning readiness, failed to draw students' interest in science, and are overlapped and repeated among the 10th grade science, high school science I and II. In particular, Earth Science II and physics II are the most unfavorable courses among students. Thus, we recommended a fundamental change be made in the new curriculum in addition to the optimization of the content. In this paper, we suggested 'topic-centered content organization' for the science elective course I, i.e., Physics I, Chemistry I, Biology I and Earth Science I that is designed for both science track and non-science track students. Since curriculum provides students with an 'opportunity to learn', a curriculum study should focus on what the 'opportunity to learn' is that students ought to be offered. Based on the result of this study, we recommended one way to select and organize the content of high school elective curriculum.

In order to examine the change in mathematical inclinationn of middle level engineering college freshmen, we analyse the change of mathematical inclination between 2011 year and 2015 year freshmen who took college scholastic ability test which are based on the national mathematics curriculum 7th and 7th revision, respectively. In medium-sized D university, 2011 year and 2015 year engineering freshmen were taken the test for mathematical inclination, the survey for mathematical background and the recognition of college mathematics and basic mathematical ability test. The outcomes of this survey are followings: Firstly, between 2011 year and 2015 year freshmen, the mean of confidence and flexibility are same, but the 2015's mean of willpower, curiosity, value and esthetics are greater than 2011's. Secondly, in the mean of flexibility, willpower and curiosity, natural science's mean is greater than humanity's. Thirdly, the mean of mathematical inclination's factors is depend on college mathematics goal. Fourthly, there is little correlation between mathematical basic ability and mathematical inclination. Moreover for 2011 year and 2015 year freshmen, the mean of mathematical inclination's factors except value is proportional to mathematical basic ability. For the success of college mathematics in engineering college, this study suggests that high school mathematics curriculum and college scholastic ability test must contain calculus. We also suggest that college mathematics class must be focused on mathematical inclination improvement.
