  • We investigated the effect of Science Writing Heuristic (SWH) on elementary students' concept formation and their retention. Also we explored the interaction effect of those with scientific attitudes. We developed mirrors/lenses lessons incorporating SWH. An experimental group of fifth grade students (n=25) had been instructed with SWH lessons for six periods while a control group (n=25) taught according to the normal science lessons based on the Korean national curriculum using teacher's guides published by the Ministry of Education. Results of pre- and post-test of understanding the concept of mirrors and lenses showed a positive impact of SWH on both male and female students. However, the retention effect after post-test revealed that SWH only had an effect on female students' scientific attitudes. SWH, therefore, could be an effective teaching approach especially on concept formation, retention effects by fostering female students' scientific attitudes.

  • This paper deals with the interfacial effects of silica fume (SF) and styrene-butadiene rubber (SBR) on compressive strength of concrete. Analyzing the compressive strength results of 32 concrete mixes performed over two water-binder ratios (0.35, 0.45), four percentages replacement of SF (0, 5, 7.5, and 10 %) and four percentages of SBR (0, 5, 10, and 15 %) were investigated. The results of the experiments were showed that in 5 % of SBR, compressive strength rises slightly, but when the polymer/binder materials ratio increases, compressive strength of concrete decreases. A mathematical model based on Abrams' law has been proposed for evaluation strength of SF-SBR concretes. The proposed model provides the opportunity to predict the compressive strength based on time of curing in water (t), and water, SF and SBR to binder materials ratios that they are shown with (w/b), (s) and (p).This understanding model might serve as useful guides for commixture concrete admixtures containing of SF and SBR. The accuracy of the proposed model is investigated. Good agreements between them are observed.

  • This study has to do with creative product in mathematics. We analyze Taylor's creative product according to a different developmental level of creativity, Taylor's creative product inventory, Besemer & Treffinger's creative products analysis matrix, O'Quin & Besemer's creative products semantic scale(CPSS) etc. The purpose of this study is to make creative products semantic scale in mathematics. O'Quin & Besemer's CPSS consists of 55 items, bipolar adjective checklist. We confirm that O'Quin & Besemer's CPSS is not fit to use for mathematics creative products. So we develop Creative Product Semantic Scale in Mathematics(MCPSS) which consists of 33 items, bipolar adjective checklist. Our result will provide convenience to mathematics teacher who guides a student make a creative product.

  • 'Science Garden' is a science program that develops acquirements of science & technology at an early stage through experiential study and inspire the spirit of scientific inquiry by carrying out laboratory work, science movie, science lecture, scientific work, outdoor activities, computer classes and science experiment which is hard to do through the regular educational course. It is targeted grade 4,5,6 students during summer and winter vacation. 'Science Garden' is conducted by selective participation freely. It is a wholelistic activity that develops children's potential talents or creativities, improves interest and attitude toward science, and also gives opportunity for self-realization by extending capacity for inquiry to show each student's ability. This study is observed and is compared how it is conducted in elementary school using qualitative study. This study is used narrative observation, in-depth interview and document analysis. Objects of narrative observation are two elementary schools, each from Jellabukdo and Gyeonggido, and 7 teachers were interviewed in-depthly. Here are results of the study. 1 A teacher in school G never takes part in student activities, tends to be indifferent to classes, but focuses on observation and experiment in laboratory. And feedback or evaluation about student's activity is never done. On the other hand, a teacher in school S guides students to understand the principals of science on themselves, and wide variety forms of activities such as role playing, discussion, and games are being done. But an effort to evaluate student's activity is not being made properly. 2. Teachers set a high valuation on the need of 'Science Garden'. Observing the way of conducting 'Science Garden', usually teachers who is in charge of science for official work is selected as a teacher in charge, and groan under a heavy burden of conducting it without anyone's help. Participating students are selected by volunteering or teacher's recommendation, but because of low Participation rate, teachers have difficulty in conducting it. Plan for conducting ‘science Garden’ is made 20 days before it, after getting an official document from Office of Education, refering to booklets produced by National Jungang Science Institute, or data from Office of Education, and internet. Teachers evaluate rarely Most school principals have interest in 'Science Garden' but parents are not well aware of it, The budget is made at the same time with the plan, and scale is varied between 200,000∼500,000 won. Because of the improper way of selecting teacher in charge, difficulty in selecting students, heavy works caused by planning, conducting the program, as well as reporting teacher's work, and lack of parents' awareness, 'Science Garden' has been conducted formally and superficially. Next gives you direction to change, for the right way of conducting' Science Garden'. It is important to motivate competent teachers to instruct students actively. For students' active participation, They should publicize thoroughly beforehand, and develope 'Science Garden' program for teachers to be able to make better use of it. Evaluation of student activities and program should be done in the aspect of developing students’ faculties. Beside of school facilities, they need to put diverse local facilities and places to practical use for immediate natural experience. And not only separate schools but also associated form of schools to conduct it is necessary.

  • 본 연구는 과학 수업 딜레마 사례에 관한 초등 예비교사의 탐구 활동이 교사교육에서 어떠한 효용성을 가지는지 탐색하는 것을 목표로 한다. 구체적으로 딜레마 사례에 관한 초등 예비교사의 탐구 과정의 특징은 무엇이며 탐구를 통해 그들의 교육적 의사결정이 어떻게 변화하는지 자세히 살펴봄으로써 딜레마 사례 활용 교사교육의 효과에 대한 시사점을 얻고자 하였다. 교육대학교 4학년에 재학 중인 초등 예비교사 20명이 참여하였으며 모둠별 프로젝트 학습 형태로 과학 수업 딜레마 사례에 관한 탐구 활동을 7주간 수행하였다. 연구자는 사전·사후 설문지, 모둠별 KWHL 표, 모둠별 탐구보고서, 모둠별 발표 자료 및 모둠별 토론 내용을 데이터로 수집하고 분석하여 예비교사의 탐구 과정의 특징과 의사결정 변화에 영향을 주는 주요 요인을 추출하였다. 예비교사들은 딜레마 사례에서 다루고 있는 과학 주제를 탐구하면서 자신의 과학 학습 과정, 탐구 과정을 의미 있는 것으로 인식하였고 자신이 탐구를 통해 과학을 학습한 것처럼 초등학생도 유의미한 과학 탐구 활동을 할 수 있을 것으로 유추하였다. 또 예비교사들은 수업 주제와 관련하여 실제 초등학생의 사고 과정이나 배경 지식 등을 다양한 방법으로 탐구하였다. 지도서와 교육과정 등의 문서를 조사하고 현장교사나 초등학생과 면담을 통해 '실제' 학생의 사고 과정이나 수준을 파악하고자 했고 이를 교육적 의사결정에 반영하였다. 또한, 딜레마 상황의 해결 방안을 한 가지 대안으로 귀결하지 않고 여러 가지 교수 방법을 비교하며 상황에 따라 다양한 대안이 가능함을 인식하기도 하였다. 이처럼 딜레마 사례는 비구조화된 문제로서 예비교사에게 일종의 문제해결 상황을 제공하였고 예비교사의 과학적 탐구, 학생의 사고에 관한 탐구를 촉발하였으며 예비교사가 교수-학습의 복잡성을 인식하는 데 일조하였다. 이러한 연구 결과를 바탕으로 딜레마 사례 활용 교사교육과 관련된 시사점을 논의하였다.

  • This study is an analysis on how current elementary teachers think about nutrition education, how they are teaching it, and problems that have occurred. The main purpose of this analysis was to deal with future problems in nutrition education by analyzing the present situation . The survey was done on 544 currently working elementary school teachers. from the 9 education departments within Seoul, 2 schools were chosen from each department by stratified random sampling. The survey used a questionnaire that was passed out personally to teachers from September 1, 1997 to the 19th. The 544 usable questionnaires were analyzed by using the teachers had nutrition education training and the average score of nutrition knowledge was 13.30 $\pm$2.73 out of 20. Nutrition education was being taught as apart of other subjects in 87.9% of the schools, and mainly by lecture. Audio visuals aids were used by 53.7% of the teachers and the most common was the VTR. Nutrition education was taught as a part of physical education and 41.5% were using teacher guides to help them. 91.9% of the teachers supported the idea of nutrition education in elementary schools. Nutrition education was supported by 80. 0% of teachers to begin when children are in kindergarten, proving that early nutrition education is supported. The analysis showed that nutrition education should be taught by parents(29.4%) , teachers(29.2%), and nutritionists(25.9%) relating that family , education, and school lunch programs should tie in with each other. 96.7% of the teachers responded that they would teach nutrition education. However, 41.0% disagreed with having a separate course for nutrition education . Proper eating habits, nutrition and its diseases, and growth with nutrition were the main categories within nutrition education and the most effect method was thought to have audio visuals, guides for teachers , and to link the subject matter with school lunch programs. The teachers main responses to problems with children were that they are too much instant food, did not eat in a variety , and had no manners in eating. Ironically, the believed that malnutrition, fainting and growth stunt were not important nutrition problems.

  • Recently environmental problem becomes such a big issue all over the world that the necessity and importance of the environmental education in school has been simultaneously emphasized. While diverse methods for the environmental education have been researched, this paper, especially focused on a teaching-learning model called GBS (Goal-based scenario), aims to provide a new learner-centered approach for the environmental education. For this purpose, this paper first briefly presents two theoretical backgrounds of GBS (i.e., constructivism and Schank's dynamic memory theory), which is followed by specific and concrete strategies and methods of how to apply GBS in class for the teacher. GBS(Goal-Based Scenario) is a learner-centered model in which learners are presented with a reality-based scenario (or task or problem) and go through several stages of 'missions' to get to a final solution of the given scenario. GBS, while completely resonant with other constructivist learning models in terms of learner-centered approaches, is distinctive from others, when it supplies more specific, structured guides of learning, called 'missions', to the students throughout the whole learning process. In a words, GBS ought to be recognized as an unique learner-centered model compromising the contradictory concepts of 'learner control' and 'structure and specifics' in learning environments still without any damage of constructivist learning principles.

  • The objective of this study is to propose the architectural basic data for the planning of kindergarten attached to the elementary school. For this study, we selected and investigated 23kindergartens in Gwangju city. The results of this study are as follows. 1) The elementary school in separated style had the advantage of securing educational space and reducing interference with students of elementary school. But it had the problem in using the facilities of elementary school. So we have to consider the kindergarten to be located near by dinning room, multi-purpose hall. 2) Concentrating the entrance, it makes the inside and outside space use easily. For the actual use, we have to establish facilities for convenience in outer-space. 3) For each room, we suggest guides as follow. The classroom and the playroom have to be combined for flexibility and supervision. In the planning of toilet, it must have sliding door for confirm the inside situation and reasonable height partition to consider the student's body-size. The shape of teacher's room must be open-type for supervising children but protect the entry of children. There is consideration for the material room and the sleeping room for all-day-long class.
