이 연구의 목적은 초등학교 6학년 학생의 분류활동에서 나타나는 사고 유형, 과정과 특징을 분석하는 것이다. 이러한 목적을 달성하기 위하여 분류활동 수행에 적합한 2가지 도구를 개발하였다. 첫 번째는 속성이 분명하게 드러나는 인공자극카드이고, 두 번째는 속성이 잘 드러나지 않는 자연자극카드이다. 서울시 영등포구 소재 D초등학교 6학년 8명을 대상으로 질적 연구를 수행하였다. 자료는 피험자의 과제 수행과정을 녹화한 비디오테이프, 피험자의 분류 기록지, 연구자의 피험자 행동 관찰, 피험자와의 면담 등 자료 삼각측정법에 의해 획득하였다. 연구결과, 6학년 학생들은 분류활동에서 속성 관찰, 속성 평가, 예비 점검, 기준 선택, 샘플 동정의 다섯 가지 유형의 사고를 하였으며, 모든 항목을 분류할 때까지 속성 관찰 $\rightarrow$ 속성 평가 $\rightarrow$ 예비 점검 $\rightarrow$ 기준 선택 $\rightarrow$ 샘플 동정의 과정을 반복하였다. 그리고 인지 경제성을 활용하여 분류하여 분류하였다. 이상의 연구 결과는 과학 분류 학습 지도에 다음과 같은 시사점을 줄 수 있다. 첫째,교사가 학생들의 분류 사고과정을 이해한다면, 보다 효과적인 분류학습 지도가 가능할 것이다. 둘째, 분류사고 과정의 각 단계를 고려한 단계별 학습지도가 필요하다.

Interviews with 24 pupils in grade 1-2 were used to investigate awareness of the relation between situation and computation in simple quotitive and partitive division problems as informally experienced. Then it was suggested how to connect children's informal knowledge and formal knowledge of division. Most subjects counted cubes or made drawing, and related these methods to the situation described in the problems. In result, quotitive division was experienced as a dealing situation, where the number of items represented by the divisor was repeatedly taken from the whole number. And estimate-adjust was the most frequently displayed way of experiencing partitive division. Therefore, partitive division with its two measurement variables can be related to a measurement model. And children should be taught column algorithms for division with estimated-adjust which pupils used for partitive division problems.

There arc numerous techniques available to appraise pupil achievement in elementary school mathematics. The teacher must utilize a variety of approaches to assess pupil growth in the mathematics curriculum. Each evaluation technique has its strengths as well as weaknesses. Thus, a specific evaluation technique may be utilized as a check on other approaches to appraisal. Pupil achievement must be assessed in terms of stated relevant understandings. skills, and attitudinal objectives. It is not adequate to appraise pupil growth in terms of understandings objectives only. Pupils must also be assessed in terms of skills objectives. The understandings acquired by learners must be utilized; thus, skills objectives need to be stressed adequately in ongoing units of study in elementary school mathematics. Adequate emphasis also needs to be placed upon pupils achieving attitudinal goals. Desireable attitudes on the part of learners aid in achieving understandings and skills objectives. A defensible program of evaluation would then stress that pupil achievement be adequately appraised in terms of understandings, skills, and attitudinal objectives.

As 10th energy consumption country in the world, it is very important to educate the importance of the energy to the elementary school students. The purpose of this class is to let the pupils understand the mechanisms and performances of tidal power generation as a renewable energy application system. To satisfy the educational goals, a lecture material and a simple type of tidal power generator kit is developed. As the survey result after lecture and experiments which include assembly and test, 'Well understood' is marked as 90% among 58 elementary students, and moreover 70% among them feel to participate in higher level course. This project shows the possibility and effect of the renewable energy education course as a service engineering, which is managed and carried out by undergraduates for pupils under the professor's guide.

The purpose of this study was to know that the 'Thinking Science' activities affects the enhancement of critical thinking skill by the logical thinking skill about pupils in the $5^{th}$ and $6^{th}$ grade of elementary school in Korea. The 19 activities of 'Thinking Science' as the teaching materials was implemented to 40 pupils in elementary school over 13 weeks. Results indicated that the experimental group presented statistically meaningful improvement in logical thinking skills(p<.05). Those teaching materials contributed to improve 3 logical sub-elements significantly(p<.05) as the proportional logical element, the probabilistic logical element, and combinational logical element. But, there was no significant improvement in conservational logical element, control of variable element, and correlational element(p<.05).

There is a question, 'Which is beautiful, a flower or a star?'. Its answer is different from one person .to another. It is only a matter of what one is interested in. It is very difficult for most school pupils, who will have non-scientific jobs, to understand science courses taught currently in school, because each science (physics, chemistry, biology, and earth science) is independently taught from the other sciences. Therefore, their knowledge of sciences obtained during their school period does not significantly help their understanding of global environmental problems. I am proposing that several scientific stories should be prepared to connect all the related scientific phenomena in order to give those pupils ideas in understanding global environmental problems. I believe that astronomy is able to play an important role in this context.

The difference between "open" mathematics education and education of "open mathematics" arises from the difference of tearcher's understanding on the meaning of "teaching and learning mathematics" in the paper. Discusses the agreements and the worries of the researchers, the teachers, the students in korea, about open educationism, firstly, Three practical cases in mathematics lesson in korea are reviewed and analyzed in the respect of learning principles, secondly. Thirdly, the paper examines how to be modified two main learning principles, individualised learning and self-regulation of learning by teachers in the process of instruction. Finally, open mathematics advocated by Fisher(1984) and closed mathematics are compared especially in the probability unit. It concludes that the open approaches in mathematics lessons in korea need to improve with respect to teacher's attitude for didactic contents or mathematical knowledge. It is argued that teacher's open or flexible understanding of mathematical knowledge is no less important than that of their pupils.ant than that of their pupils.

Understanding the nature of science is being emphasized recently among the major goals of science education. The nature of science is concerned with aims of scientific work, the status and nature of scientific knowledge, and science as societal institution. This is a review on how to investigate the pupils' ideas about the nature of science, which was suggested by Driver et al. in their book 'Young people's images of science (1996)'. The purpose of this review is to consider the methodological problems of investigating the pupils' ideas about the nature of science, and to get the implications of developing the instruments about it. The instruments, developed by Driver et al., are described as a model and their suggestions are surveyed. Several hints are given this article to develop the similar instruments.
