In this study, MBL experiments in the Korean secondary science textbooks and chemistry textbooks under the 2007 and the 2009 curriculum revision were analyzed in terms of curriculum revision era, grade, context of experiment in the textbook, field of science, topic, sensor, and publisher. As a result, 25 MBL experiments were found in the science textbooks under the 2007 revision, and 29 experiments under the 2009 revision (19 for middle school textbook and 10 for high school textbook). MBL experiments in middle school textbooks were not increased after curriculum revision while those in high school textbooks appeared for the first time. Most of them were in the textbooks for grade 7 and presented as an essential experiment rather than optional one. Motion sensor and temperature sensor were used most frequently, and oxygen sensor and carbon dioxide sensor were followed. In aspect of publishers, a frequency of MBL experiment was decreased in most textbook and some publishers didn't include MBL experiment at all. Based on these results, educational implications were discussed.

본 연구의 목적은 광합성과 관련하여 한국 국민학교 5학년과 중학교 2학년 학생들이 갖고 있는 오개념을 조사하고, 학생들의 개념이해 정도, 논리적 사고능력, 그리고 학생배경변수들 사이의 상호관계를 조사하는 것이다. 세가지의 도구들이 이 연구를 위해 개발되었다. 광합성 개념검사 (Photosynthesis Concepts Test)는 광합성과 관련된 개념들의 이해를 평가하기 위해, 삐아제의 논리적 사고력 검사(Piagetian Cogical Reasoning Test)는 PCT에 포함된 3종류의 논리적 사고들, 변인 통제, 조합적 사고력, 상관관계 사고능력을 평가하기 위해, 그리고 실문서는 학생들의 배경변수들에 대한 정보를 얻기 위해 개발되었다. 이 도구들은 20명 의 국민학교 5학년, 239명의 중학교 2학년 학생들에게 시행되었다. 이 연구의 결과는 두집단의 학생들이 "먹이를 만든다"는 의미, 먹이의 정의, 식물에 의한 빛의 사용, 식물 뿌리와 잎의 기능들, 광합성 산물, 그리고 광합성을 위한 조건들과 관련하여 오개념을 갖고 있음을 보여 주었다. 국민학교 5학년과 중학교 2학년 사이의 개념 이해의 향상은 식물에 의한 빛 이용의 본질, 한 체계내에서 생물들간의 물질 교환, 포도당, 지방, 단백질 등에 대한 지식에서 보여졌고, 그래프를 해석하는 능력에서 또한 중학교 2학년 학생들이 앞섰다. 향상을 보인 항목들은 교과서에서 보다 많은 강조점을 두거나 상위의 논리적 사고능력을 요구하는 것들이었다. 희귀분석 결과, 전년도 과학성적과 논리적 사고력이 PCT 성취도에 가장 예견력이 높은 두 변수이며 5학년의 경우 성취도의 약 22%의 변량을, 중2의 경우 성취도의 약 40%의 변량을 설명하였다. 후속연구로서 내용의 추상성, 적절성, 그리고 요구되는 논리적 능력면에서 교수조건의 변형을 통한 오개념의 변화와 감소에 대한 실험적 연구가 제시되었다.

The purpose of this study was to investigate errors on written tests of science, matters, in middle school 7th grade. Errors were defined something you have done which is considered to be incorrect or wrong, or which should not have been done. We found and classified errors, and then examined the frequency of types of errors on the written tests. A total of 167 test items from 10 middle schools were analyzed for this study. Errors on the written tests were classified into 5 types: insufficient information; unnecessary information; inaccurate information; information against curriculum; and unclear information. A total of 81 errors were counted out of 167 test items. The results of this study are expected to help teachers develop written test items to convey definite meanings by text and would be used as basic information for improving written test item standards.

The purposes of this study were to analyze problems in the experiments for comparing properties of a mixture with a compound of iron and sulfur and then to suggest the improved experiments. For this study, the experimental methods in 9th science textbooks described were analyzed and middle school science teachers were asked to conduct the experiment according to the process of the textbook and to point problems of the experiment. Two alternative experiments, which improves the problems of the toxic and provocative experiment and of distinction between a mixture and a compound by magnetic properties, were proposed. The two experiments were applied to the 10 science teachers and 60 students from a “S” middle school. They responded that the experiments were suitable for comparing properties of a mixture and a compound and helpful to understand the concept.

Purpose of this study is to investigate on the attitude toward science of science gifted and talented(G/T) middle school students. The inventory instrument used for study was a revision of TOSRA which consisted of six domains. Subjects were 131 students who had entered into Center for Science G/T Education, Seoul National University in 1999. This center is composed of five divisions: mathematics, physics, chemistry, biology, and earth science. There was no difference between genders totally, but the attitude level of male was higher than that of female in 'career interest in science' domain. Compared among domains, while the attitude score toward leisure interest in science' was the highest, 'normality of scientist' was the lowest. Whereas the attitude level was no difference among divisions except chemistry, that of chemistry division was higher than mathematics in 'adoption of scientific attitudes' domain. Thus, it is needed to provide social and national encouragement for superior science G/T students as well as to develope special programs for them so as to achieve their dreams and to contribute to scientific development of nations.

This study attempts to explore the nature of science anxiety experienced by science-gifted middle school students based on Giorgi's phenomenological research method. Among the first-year middle school students selected by the University-affiliated Science Education Institute for the Gifted, six science-gifted students with high levels of science trait anxiety and science state anxiety experience were selected. Two interviews related to experience of science anxiety were conducted with participants. As a result of the analysis, science anxiety experienced by science-gifted students was caused by setting the ideal self-concept, lack of confidence, past experiences, difficulty in contents, and something valuable. Students complained of physical·physiological, cognitive, emotional·psychological discomfort when they felt science anxiety, and recognized it as an opportunity for growth. In addition, science-gifted students were shown to cope with various ways such as confronting uneasy situations directly or refining their minds to overcome various uncomfortable symptoms that arise when science anxiety is triggered. Some students thought that no special efforts were required to lower their level of anxiety because anxiety was relieved over time. The students had both negative and positive meanings for science anxiety. The results of this study will help teachers in-depth understanding of middle school science-gifted students who experience science anxiety and provide a theoretical basis for what kind of educational environment should be created and educational programs should be provided in relation to science anxiety.
