Background Phenomenography suggests that more variation is associated with wider ways of experiencing phenomena. In the discipline of mathematics, broadening the 'lived space' of mathematics learning might enhance students' ability to solve mathematics problems Aims The aim of the present study is to: 1. enhance secondary school students' capabilities for dealing with mathematical problems; and 2. examine if students' conception of mathematics can thereby be broadened. Sample 410 Secondary 1 students from ten schools participated in the study and the reference group consisted of 275 Secondary 1 students. Methods The students were provided with non-routine problems in their normal mathematics classes for one academic year. Their attitudes toward mathematics, their conceptions of mathematics, and their problem-solving performance were measured both at the beginning and at the end of the year. Results and conclusions Hierarchical regression analyses revealed that the problem-solving performance of students receiving non-routine problems improved more than that of other students, but the effect depended on the level of use of the non-routine problems and the academic standards of the students. Thus, use of non-routine mathematical problems that appropriately fits students' ability levels can induce changes in their lived space of mathematics learning and broaden their conceptions of mathematics and of mathematics learning.

분수 나눗셈은 교육과정에 따른 교과서마다 문제 상황이나 해결 방법에서 변화가 있었고, 교과서 내용은 학생들의 학습에 직접 영향을 주기 때문에 중요하다. 본 연구에서는 우리나라의 최근 3개 교육과정과 그에 따른 교과서에 제시된 분수 나눗셈의 교육과정 성취기준, 수식 유형 및 문제 상황, 비표준 및 표준 알고리즘의 도입 과정을 분석하였다. 분석 결과, 교육과정 성취기준의 차이는 거의 없었으나, 교과서의 학년별 내용 제시에 변화가 있었다. 수식 유형에서는 교육과정별 교과서마다 차이가 있었고, 문제 상황은 다양해지는 변화가 나타났다. 해결 방법은 표준 알고리즘을 강조한 것에서 최근 교과서에서 비표준 알고리즘과 표준 알고리즘을 병행하는 방향으로 변화하였다. 제언으로 나눗셈 유형별로 내용을 세분화하기보다는 문제 상황별로 유목화할 수 있는 방안과 비표준 알고리즘과 표준 알고리즘의 연계 및 표준 알고리즘 도입 과정의 공통적 속성에 따라 일반화와 정당화를 추구하는 방안 마련이 필요함을 제시하였다.

This survey was carried out to investigate the effect of self-consciousness of nutrition knowledge and health on the nutrition knowledge and on food habits between two groups of college women, a nutrition majors and a non-majors. Questionnaires were completed by 214 nutrition majors and by 145 nutrition non-major, Nutrition majors group scored significantly higher than nutrition non-majors in the nutrition knowledge. And nutrition non-majors scored significantly higher than nutrition majors in the food habits. Most of the subjects belonged to 'Fair' and 'Poor' food habit group. And also there was a significant correlation between the nutrition knowledge score and food habits score in nutrition majors and non-majors. There was a significant and positive correlation between nutrition knowledge score and food habits score in majors but it was not observed in non-majors. The higher majors had a self-consciousness of nutrition knowledge, the higher they had habit score and nutrition knowledge score, but in non-majors it was not observed. And non-majors who had a self-consciousness of health were healthier, they were higher in the food habits scores than the jai ors. The main curriculum it is important for a good food habits that one has a responsible nutrition education in main curriculum. For the Improvement of nutrition education program we should transmit the nutritional information through an effective mass media (i.e. Radio, TV, Newspaper).

The software centered world following the fourth industrial revolution is rapidly approaching us. Countries around the world attach importance to software's ability as one of the key elements for training future human resources. In order to train software centered human resources, each university has designated Software Education as an essential curriculum for not only major but also non-majors. In the past Software Education was an education for a major, but recent Software Education was changed to the essential education that is necessary for all living in the software centered world. In the past the curriculum was focused on software development and implementation-oriented education, but recent curriculum emphasizes sequential arranging and thinking of problem solving. In order to reflect trends in recent Software Education in detail, we integrate Software Education with major concept of Computational Thinking. In this paper, we analyzed the effect of the main concept of Computational Thinking on Software Education for non-majored learners who received Software Education based on Computational Thinking (here refers to learners who major in humanities, social sciences and arts). In addition, research models of satisfaction, self-efficacy, and occupational change was established as the elements of Software Education, and it was found that there was a relation between Computational Thinking and Software Education.

This study aimed at identifying the characteristics of current science curriculum in several countries in terms of its format, aims and objectives, contents and guidelines and discussed about therm. The curricula were collected from 9 countries- The United States of America(5 states), Canada(4 Provinces), England, West Germany, France, Australia, Newzealand, Japan and the republic of China. Each country had her own characteristics of science curriculum, but there also common characteristics among several countries. First, the format of science curricula in eastern countries were very different from those of western countries. The western countries had the curriculum format which included characteristics and needs of science education, philosophy and background, aims and objectives, contents, characteristics of learners, teaching and learning strategy, teaching materials, guide of experiments, evaluation methods, and other concrete informations while eastern countries had the curriculum format which included only objectives, contents and guidelines. I think that the format of science curriculum in western countries is more recommendable than that of eastern countries. Second, the aims and objectives of science curricula in eastern countries focused on scientific knowledges and concepts, while those of countries emphasized scientific methods and attitudes. Third, the contents of science curricula were very similar regardless of eastern countries or western countries. In other words, all the countries in this study emphasized life science and earth science at lower grade level and physical science at upper grade level. Especially the observation and concrete learning activities were suggested at lower grade level and logical reasoning was emphasized at upper grade level. I think that the integrated (topic-centered) science curriculum is more recommendable than our current non-integrated science curriculum in lower grade levels. Finally, the guidelines of science curriculum in eastern countries did not suggest specific information about teaching contents, experimental methods, teaching-learning activities, evaluation methods, teaching and learning meterals, while those of western countries provided more specific information which teachers could utilize very effectively.

In accordance with the tendency of Modern Mathematics laying emphasis on Mathematical structure, that is, on axioms, it is necessary for students to be interested in structure of Geometry on Mathematics Education. In fact, it is of importance not only to obtain new ideas but also to forget old ones in the development of Mathematics. Most students do not understand the Mathematical significance of axioms, and do not know what Mathemetical truth is. Now Non-Euclidean Geometry offers opportunity to understand the essence of Mathematics better, and is no less effective than Euclidean Geometry in training student in logical inference. This thesis is a study with regard to what should be taught and how student should be guided at High school Mathematics. Chiefly Hyperbolic Geometry is discussed in connection with Abosolute Geometry. As Non-Euclidean Geometry has not appeared in our curriculum, some experiments are required before putting it into actual curriculum to find out how much students understand and how much pedagogically useful it can be. This is only a. presentation of a tentative plan, which needs to be criticized by many teachers.

The purpose of this study is to assist understanding the integrated subjects and to obtain implications required on the actual operation of curriculum by analyzing content elements and basic inquiry activities in the revised "wise lift" curriculum 2007. The result of this study is as follows. First, the formation of elements in contents of "wise life" deals with the passage of time based on changing seasons, myself and family in the 1st grade and the concept of space based on home and a village in the 2nd grade. Six main subjects and twelve activity subjects are presented per each grade. Second, number of activity subjects and content elements are reduced as compared with 7th curriculum so that the responsibility of operating classes based on activities is reduced and the purpose of rationalizing contents is somewhat fulfilled. Third, eliminating a relevant domains decisively when presenting the activity subjects assures the identification and purpose as the integrated subject focused on inquiry activities. Fourth, the result of analyzing the course-relevance on content elements shows that the allotment per each domain and course is less considered but the relevance of social studies is higher regardless of non-course characteristics as the integrated subject. Fifth, according to the component ratio of basic inquiry activities, 'Observing' and 'Debating' were presented as the most essential activities, and 'Measuring' and 'Making' were relatively low. By considering characteristics of course requiring balanced and various experiences of inquiry activities, additional discussions are required on appropriateness of the component ratio. Sixth, 'Observing' was increased and 'Debating' and 'Making' were decreased on the main activities in this revised curriculum as compared with 7th curriculum.

Purpose: This study purposed to examine the effect on health educational curriculum by grasping knowledge, attitude, and the extent of practicing it after giving a health education curriculum for 17 hours. Methods: This study was a non-equivalent control group pretest-posttest conducted with the first-graders enrolled in a middle school students in Gyeonggi Province. A total of 191 completed questionnaires from the test group and the control group each were used for the final analysis. The survey period was from March 5 to March 13, 2009 before the education was given from July 20 to July 25, 2009 after the education. A total of 38 questions were used to measure knowledge and a total of 39 questions were used to measure attitude and practice. This study used $x^2$ test, ANOVA, and t-test, Paired t-test. Results: After the health education curriculum was given, the test group s knowledge of health education was found higher than that of the control group. There was a difference between two groups, but considering the perfect score of 38, the knowledge scores of both groups were not high. With regard to each group s attitude and practice of health education, the study compared the scores obtained before and after the education and found that the test group had higher scores than the control group, showing a significant difference. Conclusion: In order for a health education curriculum to successfully have favorable influence on the health of teenagers, the curriculum should be offered for a more extended period of time than 17 hours and as a compulsory course, not a selective one, so that all the students can develop their health management capabilities.
