학생의 과학 지식 성취도에 대한 장기간의 경향성은 과학 교육 정책의 효율성을 점검하는데 매우 중요한 요인이다. 그러나 지금까지 우리 나라 학생들의 학업 성취도의 경향성을 이해해보려는 진지한 노력이 현실적으로 거의 없었다. 최근까지 한국교원대학교 과학교육연구소에서는 전국에 있는 초·중·고 학생들을 대상으로 학생들의 과학 지식 성취도를 알아보기 위한 연구를 진행시켜왔다. 연구의 첫 단계에서는 평가 문항을 개발하였다. 두 번째 단계에서는 개발된 문항을 전국적으로 투입하고 그 결과를 수집하여 2년간의 변화를 분석하는 것으로써, 이 논문은 두 번째 단계에 관한 내용을 담고있다. 이 연구에서는 권재술 등(1998)이 개발한 국가 수준의 과학 지식 평가 도구를 일부 수정하여 사용하였다. 1997년에는 전국적으로 8,766명의 학생을, 1999년에는 4,398명의 학생을 조사 대상으로 하였다. 조사 대상은 지역별, 성별 등을 고려하여 우리 나라 전체 학생의 모집단을 대표할 수 있는 표본으로 선정되었다. 연구 결과, 2년 동안 초·중·고 학생들의 과학 지식 성취 수준의 서로 다른 변화를 확인할 수 있었다. 초등학생의 경우는 성취도가 감소하였으나, 고등학생의 경우는 증가하였고 중학생의 경우는 두 시기에 의미 있는 차이가 없었다. 과학 지식 영역의 하위 영역별 분석 결과를 보면, 초등학생의 경우 개념 체계에 대한 지식 수준을 유의미하게 향상되었으나, 사실과 원리에 관한 지식 수준은 낮아졌다. 반면 고등학생의 경우는 지식 수준이 향상되었으며 특히, 사실 영역에서 크게 향상 되었다. 연구에서는 이 자료를 성별, 지역별, 행동 목표 수준 그리고 검사 문항의 상황 등으로도 나누어서 분석하였다. 한국교원대학교 과학교육연구소에서 개발한 과학 성취 수준 점검 시스템은 국가 수준에서 학생들의 과학성취도를 점검하는데 효과적인 도구가 될 것이다. The long term trend of studensts' science achievement is a very important factor to check the effectiveness of science educational policy. However, up to date no such effort to understand the trend of Korean students' science achievement has been put into action. Recently, the Science Education Center in Korea National University of Education has been attempted to collect nation wide data for students' science achievement. The first part of the effort was to develop item pools. This study was the second part to collect nation wide data and to check any change during the two year time interval. In this study, the item pools developed by Kwon et. al.(1998) were used with some modification. The data were collected two times; February 1997 and March 1999. The subjects collected nationally were 8,766 students in 1997 and were 4,398 in 1999. The subjects were collected randomly but stratified by region and sex. As the results, the trends of achievement change during the two years were different from elementary to high school. The achievement scores were decreased in elementary schools and increased in high school. In case of middle schools, the change was not significant. However, even in elementary schools the knowledge on theory was increased significantly while knowledge on facts and principles were decreased. In contrast, the knowledge on fact showed the most increase in high schools. In this study, the data were analysed in light of region, sex, behavioral objective levels(ability) and context of test items. The science achievement monitoring system developed by the Science Education Center in Korea National University of Education can be an effective tool for monitoring students' achievement on the national level.

관성개념에 대하여 자기의 생각과 불일치하는 상황의 유형에 따른 학생의 반응

권재술,이경호 한국과학교육학회 1999 한국과학교육학회지 Vol.19 No.4

이 연구의 목적은 자신의 생각과 불일치 하는 관성현상에 대한 학생들의 반응을 알아보는 것이었다. 불일치 상황은 과학개념 변화 모형(권재술, 1989)을 참고하여 두 가지로 정하였다. 면담을 통하여 세가지 관성관련 문항에 대한 학생의 사전 개념과 불일치 상황에 대면한 후의 반응을 조사하였다. 연구결과, 불일치 상황 1에서 많은 학생들은 새로운 상황을 설명하지 못하였으며, 일부학생들은 자신의 선개념을 버리고 새로운 개념으로 그 상황을 설명하였다. 그러나 이들 학생들의 새로운 개념은 대부분 비과학적인 개념이었다. 불일치 상황 2에서 대표적인 학생 반응은 자신의 선 개념을 부분적으로 수정하면서도 본질적으로는 변화하지 않는 동화전략이었다. 한편, 학생들의 개념은 물항에 따라 다양하였으며, 불일치 상황에 대면한 후에 이전보다 더욱 다양한 개념 유형을 보여주었다. The purpose of this study was to find out the responses of students confronted with discrepant situation about inertia concept. We had developed two discrepant situation patterns according to conceptual change model(Kwon, 1989). And we examined the students' responses to the discrepant situations of the 3 inertia problems by interview method. In the result of this study, many students in discrepant situation 1 failed to explain the situation Some students gave up their preconception and showed new conception that was different from preconception. But most of their new conceptions were not scientific conception. In discrepant situation 2, the major characteristics of students responses were the assimilation strategies. Many students modified their preconception in some part but didn't change it. After discrepant situation, students' conceptions were changed more diverse conceptions than preconceptions.

학문 중심 과학 교육의 문제점과 생활 소재의 과학 교재화 방안

권재술 한국과학교육학회 1991 한국과학교육학회지 Vol.11 No.1

The new movement in science education in America and Europe has been heavilly oriented into technological and soceital aspect of science since 1970. However, this spirit has not been well informed in Korea and not adapted in science education. This paper aimed to arouse Korean science educators attention to everyday situation as a science education context. In this paper, the discipline centered science education was briefly reviewed and problems related to the philosophy was pointed out. At the same time the researcher introduced STS context as a science education objective, and elaborated the three elements(physical situation, technological situation, and societal situation) of the context. In the paper, the advantages of the use of everyday context in science education were examined. The advantages were analysed in terms of the nature of science, learning psychology, integrated science, and societal aspect of science education. The paper also suggested the criteria to select teaching materials from STS context. The suggested criteria were the degree of science concepts involvement, frequency of experience, strength of experience, and possibility of direct experience.

Pascual - Leone 의 신 피아제 이론에 의한 오개념의 본질에 대한 심리학적 접근

권재술,안수영 한국과학교육학회 1995 한국과학교육학회지 Vol.15 No.2

The purpose of this article is to find out psychological mechanism on the core of misconceptions. Theoretical frame to search for the core of misconceptions is based on the Pascual-Leone's neo Piagetian theory. Although Pascual-Leone's theory is a cognitive developmental theory, its psychological mechanism gives us new insights on misconception. According to the comparison between Pascual-Leone's psychological mechanism and the common specifics of misconceptions and their items, conclusions could be summarized as follows: 1) Children's misconceptions and LC learning structures have the same nature. 2) Structures in items of misconceptions and misleading factor structures in cognitive tasks affect mental process with the same mechanism. 3) LC learning structures was activated preferentially in knowledge structures by F operator, with the same activation mechanism, the process children's misconceptions was activated firstly among other conceptions could be explained.

대학수학능력시험에서 과학탐구 영역의 분석

권재술,김상철 한국교원대학교 과학교육연구소 1994 청람과학교육연구논총 Vol.4 No.1

The Ministry of Education established the plan to adopt a new college enterance examination system, so called Scholastic Ability Test for college, from 1994. The National Board of Educational Evaluation had carried out 7 experimental trials for the new examination system. Eventhough, the governmental officials advertised the purpose and characteristics of the new examination system, many students and parents did not understand the essential point very well. In this study the researcher tried to analyze the 7 trial examination items and the first Scholastic Ability Test for college carried out 1993. In this study, the researcher tried to find out all the items appeared in the 7 trials. In the analysis, all the individual items from the 1st trial to the 7th trial were used. The research results showed that the items were evenly distributed in all the four areas(Physics, Chemistry, Biology and Earth Science) of science content; however, they were heavily concentrated on data or information analysis categoris in the inquiry domain. In the domain of context, laboratory context was the major item context. The scores were also analyzed. The results showed that no significant difference between male and female students. However, science track students showed higher achievement scores than the non-science track student. The examination result showed high correlation with the tests routinely have carried out in schools. The over all analysis showed the new examination system showed very different characteristics to the conventional tests. Therefore, for the student to get successful result in the Scholastic Ability Test, they should change the way of study. They should try to understand scientific concepts rather than to memorize them. They should invest their time to carry out real experiments rather than to focus on the princples and laws of science. One of the most important thing would be for the student to apply what they learned to real life situations.

통합 과학 과정의 접근 방법에 관한 비교 연구 : 개념 중심 방법과 과정 중심 접근 방법을 중심으로

권재술,박범익 한국과학교육학회 1978 한국과학교육학회지 Vol.1 No.1

In this study, concept centered approach and process centered approach in developing integrated science curriculum were compared and compromised between two approaches. It seems that two approaches are in antagonistic relations. The superficial conflictions getween two approaches are not because they are antagonistic in their nature, but because their interesting points are different. The concept centered approahc is interest in fundamental scientific concepts and the process centered approach is interested in scientific enquiry. If science is the composition of enquiry processes and concepts produced by enquiry processes, scientific enquiry process and scientific concept must not be inconcistant. Although concepts are not unchangeable, new concepts and advanced concepts are based on the old concepts. Enquiry activity which is not based on concepts also cannot be significant enquiry. Although fundamental concepts in science is very important, in order to apply concepts, to various phenomena, and to understand concepts more deeply the student should understand concept through the process by which the concepts are derived. As we have discussed above, only the concept centered approach or the process centered approach itself is not complete. Comparing these two uncomplete approaches to integrated science curriculum, we can find out that two approaches are in complementary relations. Because integrated science is based on the idea that natural phenomena should not be understood in fragments, but should be understood as mutually related system the integrated science curriculum includes both the fundamental scientific concepts and scientific enquiry processes.
