The purpose of this study is to survey and analyze difficulties in teaching and learning elementary school science on the chapter titled 'electric circuit'. 28 elementary school teachers who teach 5th grade science and 73 5th grade students in elementary school were taken part in this survey. The pilot questionnaire was distributed to find out both the degree and the reason of difficulties in teaching and learning. The answers are analyzed with four areas to extract elements which make class difficult; Learner factors (L), Instruction factors (I), Curriculum & textbooks factors (C), and Environment factors (E). The results are as follows. (1) It can be seen that both students and teachers feel the highest difficulty in 7th lesson 'the direction of current', while they felt little difficulty in lesson 3 'conductor and nonconductor' and lesson 8 'the safety of electricity'. (2) The most mentioned reason of difficulties in teaching and learning was Learner factors (L). (3) Teachers felt many difficulties in experimental environment. On the other hands, students didn't think experimental failures as serious trouble. (4) Students felt many difficulties in new terms and hazy concepts or expressions. (5) Teachers felt a lot of difficulties in those from Curriculum & textbooks factors.

The purpose of this study is to investigate the psychological hierarchy structure of science concepts and to determine the effective teaching order by comparing the teaching effects of the psychological hierarchy order with those of teaching order of the current text in order to inquire validating evaluation framework of science curriculum sequence. Key concepts were selected by tasks analysis in the seven units of elementary and secondary school curriculum. Concept formation tests were developed to evaluate each concepts achievement,. The test items were made according to each of the concepts based on 12 prototype tasks developed by Frayer(1969). To identify the students' psychological hierarchy the test items were administrated to elementary and secondary school students. Ordering theory was used to identify the students' psychological hierarchy. Nonequivalent control group pretest-posttest design was used in this study as an experimental design. Teaching with psychological hierarchy order was applied tp experimental group and teaching with concept order described in the current text was applied to control group. The major results of this study are as followings: 1. The students' psychological hierarchy structures are different from logical hierarchy structures. 2. The science teachers' psychological hierarchy structures are different from not only logical hierarchy structures but also students' psychological hierarchy structures. 3. The mean score of experimental group applied psychological hierarchy order is significantly higher(p<.05) than the control group in the concept achievement.

이 연구에서는 2000년 여름부터 2001년 여름까지 1년여 동안 실시된 순환학습/STS 과학교사 현직 교육을 받은 한 과학교사의 수업 지도안 개발 과정을 기술하고, 그 과정에서 구성주의와 일치하는 방향으로 그 교사의 과학, 과학 학습, 과학 수업 관점의 변화를 알아보았다. 참여 교사는 개념에 기초한 실험 중심의 수업 지도안에서 실생활을 적극 반영한 학생 활동 중심으로 수업 내용을 바꾸어 갔다. 동기 부여 측면에서 학생들이 쉽게 경험할 수 있는 실생활의 소재를 활용하였고, 학생들의 오개념을 반영한 수업을 위해 간단한 실험에서 학생들의 의견을 많이 듣고 개념 변화로서의 학습을 고려하였다. 그 교사의 이러한 구성주의적 반응은 현직 교육 기간 동안에 긍정적인 방향으로 증가하였다. 실제 수업 지도안에 반영된 변화는 면담을 통해서 그 교사가 과학, 과학 수업, 과학 학습 등에서 확인되었다. 특히 7차 교육과정이 학생 활동을 강조하는 방향으로 개편된 점을 감안할 때 순환학습과 STS에 기초한 수업 지도안 개발은 현장에서 더욱 요구되는 사항으로 생각된다.

It is simply not true that anyone who can speak English can teach it. Language teaching is both a science and an art; its methods are based on a theoretical foundation and implemented by techniques. However, at a time like the present, when the scientific justification for our methods seems to be uncertain, we should concern ourselves less with theory and more with developing techniques that work with our students. The success of language teaching must be evaluated by the effectiveness of the techniques used. The purpose of the present study is to suggest some useful techniques that the teacher can utilize in teaching English as a foreign language in the elementary school. The techniques suggested are based on the investigation of the characteristics peculiar to children. The investigation takes into account cognitive, affective, and linguistic factors affecting specific techniques. The goal of language teaching is communication and all techniques should move toward this end. The resourceful teacher will provide techniques which exact more and more from the students and less and less from the teacher.

The purpose of this study was to investigate the change of elementary school students' conception on the movement of the moon, after teaching a lesson about the lunar phase which focused on concrete activities. The 396 subjects in this study consisted of intact groups of second, third, fourth, fifth, and sixth grade students. Pre-test and post-test instrument concerning on the conception in the movement of the moon were developed after reviewing the related literature and curriculum. Prevailing conceptions were identified by frequency of each conception. Then, the pattern of change and consistency of each conception were analyzed in comparison pre-test with post-test. To figure out the effect of teaching, the GEFT and the GALT instrument were administered to analyze it by gender, cognition mode and level. SPSS/WIN programs were used to process the data. The result showed that teaching 'movement of the moon' was the most effective in fourth grade. The effect of teaching 'changes in shape of the moon' was effective regardless of their sexes. Teaching 'changes in shapes of the moon' was more effective for the students whose cognitive modes were field-independent, than those filed-dependent. But the improvement by the teaching was not significantly different. The pre-score by cognitive level was significantly high in the order of the formal operational, transitional stage and the concrete operational stage. But the improvement of conception after teaching was high in the order of the concrete operational, transitional stage and the formal operational stage. That is to say, teaching was more effective as the cognitive level lowered.
