  • This study developed the sex education program based on the 'reproduction and development' unit of the middle school science, and examined its effectiveness on middle school boys' sex-related knowledge and attitude towards sex. The sex education program consisted of six topics of the structures and functions of generative organs, the importance of life, abortion, the human generation process, venereal diseases and AIDS, and responsibility of self-determination on sexual behavior. The results indicated that the experimental group demonstrated the statistically higher scores of the knowledge on sex than the control groups' scores, especially in the subcategories of 'pregnancy and delivery' and 'sex-related health'. However, both groups did not display any statistical difference on the attitude toward sex. In the subcategory of the attitude towards sex, the experimental group showed the statistically higher scores on 'self-determination and selection' and 'a health relationship'. In addition, the Pearson correlation results indicated the strongest relationship between the attitude toward sex and 'the self-determination and selection'. These results implicated that the sex education program related to the unit of reproduction and development in the middle school science helps the middle school boys develop the better knowledge and attitude towards sex.

  • Mathematics education is accomplished by systems such as mathematical curriculum and tools such as a textbook which reflects such systems. Human beings make such systems and tools. Therefore, a viewpoint of mathematics of those who make them is an important factor. The view point of mathematics is formed during doing and learning mathematics, but the already formed viewpoint of mathematics affects doing and teaching mathematics. Hence, it will be a factor which affects basically that those who employ themselves on mathematics education have a certain viewpoint of mathematics. This article presents dialectical materialistic viewpoint as the viewpoint of mathematics which affects fundamentally on mathematical teaching-learning practice. The dialectical materialism is carried through the process and result of mathematics development. This shows that mathematical knowledge is objective. Mathematical knowledge has developed according to three basic rules of dialectical materialism i.e. the transformation of quantity into quality, the unification of antagonistic objects, and the negation of negation. This viewpoint of mathematics should offer the viewpoint of mathematics education which is different from the view point of absolutism, relativism or formal logic. In this article I considered mathematics separating standpoint of mathematics into materialistic viewpoint and dialectical viewpoint. 1 did so for the convenience of analysis, but you will be able to look at the unified viewpoint of dialectical materialism. 1 will make mention of teaching-learning method on another occasion.

  • A fraction is one of the most important concepts that students have to learn in elementary school. But it is a challenge for students to understand fraction concept because of its conceptual complexity. The focus of fraction learning is understanding the concept. Then the problem is how we can facilitate the conceptual understanding and estimate it. In this study, Moore's concept understanding scheme(concept definition, concept image, concept usage) was adopted as an theoretical framework to investigate students' fraction understanding. The questions of this study were a) what concept image do students have\ulcorner b) How well do students solve fraction problems\ulcorner c) How do students use fraction concept to generate fraction word problem\ulcorner By analyzing the data gathered from three elementary school, several conclusion was drawn. 1) The students' concept image of fraction is restricted to part-whole sub-construct. So is students' fraction understanding. 2) Students can solve part-whole fraction problems well but others less. This also imply that students' fraction understanding is partial. 3) Half of the subject(N=98) cannot pose problems that involve fraction and fraction operation. And some succeeded applied the concept mistakenly. To understand fraction, various fraction subconstructs have to be integrated as whole one. To facilitate this integration, fraction program should focus on unit, partitioning and quantity. This may be achieved by following activities: * Building on informal knowledge of fraction * Focusing on meaning other than symbol * Various partitioning activities * Facing various representation * Emphasizing quantitative aspects of fraction * Understanding the meanings of fraction operation Through these activities, teacher must help students construct various faction concept image and apply it to meaningful situation. Especially, to help students to construct various concept image and to use fraction meaningfully to pose problems, much time should be spent to problem posing using fraction.

  • Mathematics was the main domain of PISA 2012, and both paper-based and computer-based assessment of mathematics (CBAM) were conducted. PISA 2012 was the first large-scale computer-based mathematics assessment in Korea, and it is meaningful in that it evaluated students' mathematical literacy in problem situations using dynamic geometry, graph, and spreadsheet. Although Korea ranked third in CBAM, the use of ICT in mathematics lessons appeared to be low. On the other hand, this study focused on Singapore, which ranked first in CBAM. The Singapore Ministry of Education developed online programs such as AlgeTools and AlgeDisc, and implemented the programs in classes by specifying them in mathematics curriculum and textbooks. Thus, this study investigated influential factors on computer-based assessment of mathematics by comparing the results of Korea and Singapore, and aimed to provide meaningful evidence on the direction of Korea's ICT-based mathematics education. The results showed that ICT use at home for school related tasks, attitudes towards computers as a tool for school learning, and openness and perseverance of problem solving were positively associated with computer-based mathematics performance, whereas the use of ICT in mathematics class by teacher demonstration was negatively related. Efforts are needed to improve computer use and enhance teaching techniques related to ICT use in Korean math classes. Future research is recommended to examine how effectively teachers use ICT in mathematics class in Singapore.

  • This study investigated the effects of the 'Meeting With Scientists' program on children's stereotypical images of scientist. To do those, 36 children of a fifth grade class participated in the program for one month. The program consisted of two main activities:(l) participating in scientists' lectures and exchanging e-mail with them; and (2) visiting web sites about scientist and science, and exchanging e-mail with scientists at the sites. The results of the study can be summarized as follows: First, after participating in the program, children showed the significant decrease of several stereotypical items, such as facial growth of hair(bald hair beard), symbols of research, and age of the scientist. Second, the most popular source of the images was the visual media at the pretest but the source was changed to the visiting and participating scientist's lecture, and internet at the posttest. The latter items appeared a significant difference between the pretest and the posttest, The results indicate that the program is effective to decrease of children's stereotypical physical image of scientist.

  • It was proposed that proper problem solving practice should improve students' questioning in physics. In the previous researches, improvement in students' questioning was observed after practice of making questions given the examples of desirable questions. In this study, the problem solving strategies used by experts were introduced to students in the form of step-by-step guide to follow in problem solving practice. The directions in the guide were concrete and operational for students to understand the expected behaviors explicitly. It was assumed that students could pinpoint the difficulty specifically through this guide, which would result in positive effects on students' recognition and expression of their own questions. The subjects in this study were college freshmen enrolled in the introductory physics for science or engineering major. The physics problems from the textbook were solved and practiced in the traditional way for controlled group. Worksheets designed to follow experts' problem solving strategies were used for the experimental group. Two groups were taught in the same way during lecture part of the class. Students were asked to describe the difficulties they had during homeworks or tests. Questions in this study means these descriptions written by students although they were not necessarily in the form of interrogative sentences. The questions were analyzed both in quantity and quality. Quantitatively, more students spontaneously turned in their questions in the experimental group than in the controlled group. Regarding the quality, there were more students in the experimental group than in the controlled group who described their difficulties in detail or recognized the need for the procedural knowledge.

  • Student understanding of the nature of science is necessary not only because it is helpful for solving everyday problems with growing science literacy, but also because it influences students' science learning. Therefore, it was necessary to investigate student views on the nature of science under the 7th national curriculum and compare with those before the 7th national curriculum in order to probe the elements which contribute to changes in student views on the nature of science. A significant number of differences were found between subdimensions of views on the nature of science through the comparison. High school students under the 7th national curriculum had more relativistic, instrumental, and deductive but less process-oriented views than high school students before the 7th national curriculum. The differences between mean values which showed high school student views on the nature of science under and before the 7th national curriculum were significant, except for the subdimension of instrumentanlism/realism. In particular, high school students under the 7th national curriculum possessed a contextual view, whereas those before the 7th national curriculum possessed a decontextual view. Although other factors might be the cause for differences found in this study, we argued by discussion that differences among textbook contents seemed to be the major factor.

  • This study aims to explore the usefulness and the way of practical use of dilemma episodes in science teacher education by the responses of teachers on the given dilemma episodes and connected discussions. The research based on the idea of constructivist teacher education, the assumption that dilemmas can provide teachers with an open investigation context, an understanding of nature of science education. The dilemmas episodes in Wallace and Louden(2002) were introduced and discussed in order during graduate course to 11 elementary teachers. Perception on the reality and importance of given dilemmas differed by topics, but many of them were very similar to their experiences, brought active discussion on the issues. Some could not arouse sympathy because of cultural differences. The teachers recognized the dilemma episodes provided thoughtful reflection on their own teaching, opportunity of sharing experience and knowledge with peers, overall view for science education. Most of them gave positive opinion on the use of dilemma episodes in teacher education. Upon these teachers' responses and exploratory research experiences, some practical suggestion were made for science teacher educators.

  • In this study, with the problem of "What is the desirable illustrations?", the problem points of the existing textbooks were analyzed, and the opinions of experts concerning desirable illustrations were examined through questionaire survey, and by developing 'Analysis Framework of Illustrations', and Korean-Japanese 'science' textbooks were analyzed and compared with. The conclusions for the direction of korean 'science' textbooks are summarized as follows : 1) The numbers of korean illustrations should be more about two than one of per one page of the existing textbooks. 2) The korean illustrations for the 6th grade should be more largely inserted. 3) The more econmic space utilizing measure should be groped for looking at from the such side. 4) Though the kinds of Korean illustrations are mostly composed of photographs, pictures, illustrations, cartoons, etc. should be positively utilized. and the shapes of photographs should be diversified by such as square, round shape,omissions of background and others. 5) The distribution of players by sex should be considered envenly for male and female from the ascendency of male (1.5: 1). 6) It was found that it is desirable for the formation of role of illustrations of 20% for motive inducement, 45% for guidance for experimentation, 30% for presentation of data, and 5% for presentation of the results of experimentation. 7) The illustrations for guidance for experimentation should present important stages of experimentation process regardless the number of illustration. 8) It would be advantageous for motive induction to find the subject matters as possible as from the children's close actual life. 9) It is necessary to induce more freely method in utilizing Printing plate for inserting illustrations. 10) It is the result of research that the existing Korean textbooks are not suitable in inducing interest, and the positive strategy to induce interest is demanded. 11) It is required to select their location freely in accordance with the content regardless the. 12) In order to develop such illustrations, it is required to cultivate expert illustrators, and more economic investment is required for development of illustrations. The emphasis matters of revision of the 6th educational process of 'Inducement of study motive and emphasis on interest' is the change of presenting form and method of illustrations, which is expected to be rewarded with much good fruits.
