  • This paper aims to review the overall development of constructivist approaches in science education research from two different perspectives, that is a summary of the past development in science education in general and a report of the outline of a recent research project on students' physics misconceptions in particular. In the summary of the past development of constructivist science education the introduction of constructivism as well as its psychological and philosophical backgrounds are briefly reported. Then main findings of the researches of constructivist approach are discussed in terms of the features of students' misconceptions, of the ways of effective conceptual change, of the implications toward school science education, and of the criticisms given to the constructivist approach. In the report of a recent development in addition to its background necessity and implications, the research structure and the format of the data analysis of the study on the map of students' physics misconceptions are presented. It is particularly emphasized that the practical informations and suggestions for actual teaching of school science, such as the database(DB) of students' misconceptions and teaching guides, are of most practical and effective values in order to maximize the advantage of the constructivist approach to science education.

  • The purpose of this study is to investigate the misconceptions and the understanding of students on diffusion and osmosis, and to examine the shifts in concept development that result from maturation and additional instruction. In addition, the textbooks were assessed for the sources of the misconceptions. The subjects of this study were 195 students in middle school, 191 students in high school and 195 students in university in Seoul. And the multiple-choice test developed by Odom and Barrow(1995) was used. The results were analyzed by two-way ANOVA in the statistical packages SAS. The major findings of this study are as follows. 1. The mean score of the understanding on the concepts of diffusion and osmosis of junior high school students was 31, that of high school students was 51 and that of university students was 67. In this study, the higher grade students got the higher scores, and it showed significant difference(p<0.01). 2. The mean score of girls was higher than that of boys in all grades. And the difference of the score according to gender showed great difference in high school(p<0.01). 3. An analysis of the patterns of misconceptions about diffusion and osmosis indicated that certain misconceptions prevail across grade levels. 4. An analysis of the contents of textbooks indicated that textbooks may be the source of students' misconceptions about diffusion and osmosis.

  • The purpose of this study was to investigate misconceptions regarding the structure of flowers and the function of the course based on the 'Flower' section of 5th grade elementary school science courses. It also sought to investigate how misconceptions are changed before and after the application of a Driver learning model, and finally analysing any differences in the correction of misconceptions. A questionnaire was created for 199 5th grade elementary school pupils. The major results before and after using an applied Driver learning mode teaching plan are as follows: In the response for questions, 13.6% and 14.5% of misconceptions were corrected for male and female pupils, respectively. For rural and urban pupils, 14.8% and 11.2% of misconceptions were corrected, respectively. In the comparison of male and female pupils according to the reasons for selection of responses before and after using an applied Driver learning model teaching plan, 27.8% of male and 30.0% of female pupils scientific conceptions showed improvement. For rural and urban schools, 26.6% and 32.2% of scientific conceptions were improved, respectively. Data from this study may help teachers to reconsider their own conceptions regarding the study of the flower as it is presently conducted in elementary school.

  • 본 연구는 학습자들이 수학과 디지털교과서를 사용해 자기주도적 학습을 할 때 겪는 문제점이 무엇인지를 파악하고, 그 원인을 분석하여 추후 디지털교과서 설계와 관련된 시사점을 도출해 보고자 하였다. 이를 위해 수학 [6-나] 디지털 교과서의 '분모가 같은 분수의 나눗셈' 단원을 초등학교 6학년 8명의 학생이 자기주도적으로 학습을 하는 과정을 think aloud 방법을 통해 관찰하고 분석하였다. 학습이 끝난 후 학생들은 사후평가지를 작성하였으며, 연구자와의 면담에 참여하였다. 실험 결과 디지털 교과서를 이용한 동분모 분수의 나눗셈 학습에서 학생들이 나타내는 오류의 유형은 크게 '수학교과서 특성상의 오류'와 '디지털교과서 기능 및 설계상의 오류'로 나눌 수 있었다. 특히 디지털교과서의 잘못된 설계는 오히려 학생들의 오개념과 오류를 유발하는 것으로 나타났다. 이는 디지털교과서 설계시 학습자의 오개념을 유발할 수 있는 요소를 고려해야 함을 시사한다.

  • 이 연구에서는 5개 사범대학의 화학교육과 4학년 87명을 대상으로 중학생들의 오개념에 대한 지식과 인식, 그리고 교육요구를 조사하였다. 검사 도구는 학생들의 화학 오개념에 대한 지식 검사지 및 인식 검사지와 학생들의 오개념을 접한 경험과 관련 교육요구에 대한 교육요구 검사지로 구성되어 있다. 지식 검사에서 대부분의 예비 화학교사들은 물질의 입자성과 관련된 학생들의 오개념 유형을 충분히 인지하지 못하였다. 인식 검사에서는 학생 오개념에 대한 지식의 필요성을 높이 인식하고 이를 수업에서 활용하려는 의지가 컸다. 그러나 구성주의적 관점에서 오개념 활용 방안을 제시한 예비 화학교사들은 적었다. 학생들의 오개념은 주로 사범대학 화학 교과교육학 강의 및 강의 자료를 통해서 접했으며, 과제 수행이나 수업 시연 및 교육실습에서 학생들의 오개념 유형과 대처 방안에 대한 지식 및 관련 교수-학습 자료 등의 부족으로 인해 어려움을 겪고 있었다. 또한, 오개념 관련 강의 및 실행에 대한 교육요구가 높았다. 이에 대한 교육적 함의를 논의하였다.

  • The purpose of this research is to provide useful data in forming sound scientific concepts by investigating elementary students' non-scientific concepts related to their concepts of biological adaptation, and by analyzing the general inclinations and causes of some misconceptions. Twenty-four objective questions were designed to be given to 5th and 6th grade elementary students in order to investigate their concepts of biological adaptation. According to the test results, they formed scientific concepts in most questions. But they appeared to have many misconceptions in some parts which should be guided by the teacher's additional explanations rather than by the education curricula's focus. There are some cases where the 6th grade students had more misconceptions than the 5th grade students who were not systemically taught the concepts of biological adaptation, for the reasons of strengthening or maintaining the misconceptions by confusing the contents of learning. Male and female students have different scientific concepts of different questions according to their interest and attention. Therefore, it is necessary to develop various teaching-learning data which can help the teachers' additional explanations about the concepts of biological adaptation and invoke students' interest and attention, and to seek appropriate measures to form sound scientific concepts among teachers as well as students.

  • The aims of this research are to analyze elementary preservice teacher's conception and causes of their misconceptions on biological reproduction and inheritance. In future, it would be also to provide useful data for the effective teaching-teaming method in the elementary school as well as opportunities to correct their misconceptions, which help elementary preservice teachers have the appropriate scientific conceptions. Thirty kinds of test questions were designed in science curriculum for elementary students and biology textbook for university students in order to develop reproduction and inheritance's concepts. The questionnaire was given to 166 junior students of university of education in a local city. All statistical analysis was performed using SPSS version 10.0 program. The major results are as follows: Among 30 test questions, 2 questions in plants, 5 questions in animals and 2 questions in gene were appeared as misconceptions over $50\%$. The major reason to hold the misconceptions was influenced by 'learning up to now' category. The selection reasons of response were significantly different between scientific conceptions and misconceptions in 10 questions by analysis of variance. The gender also showed statistically significant differences between scientific conception and misconception in 3 questions by $\chi^2$ test. The selection reasons according to gender were significantly different between male and female students in 5 questions. For the reasons in forming misconceptions, they may cause by stereotype, conscious priority, differences of experiences, interest or attention, lack of professional Knowledge, and so on. Therefore, it was concluded that this research may help elementary preservice teachers to reconsider their conception for reproduction and inheritance and to be successful in science instructions fur elementary students.

  • This study evaluates on students' understanding and misunderstanding of homeostasis, classification of animals and plants, and food production in plants, and analyzes the teacher factor as a possible source of students' misconception. A total number of 863 students and 47 biology teachers at the middle and high school were randomly selected. Students' conceptions and misconceptions were measured with concept evaluation statements (CES) which was translated into Korean by author. The CES was developed and validated by Simson and Marek (1988). Teacher's misconceptions were investigated the way in which teachers marked students' work. The supposed answer given to the teachers to mark was based on misconceptions held by students tested in concept evaluation statements. The results of this study are as follows : 1. 0% of 7th Grade students, 4.5% of 9th Grade students and 5.4% of 11th Grade students understood homeostasis. There was a significant difference at the level of students' understanding of homeostasis according to schools and gender(P<0.05). Many students had a tendency of understanding the conception of the homeostasis by experiences and unscientific use of everyday language rather than a scientific concept. 2. 0.4% of 7th Grade students, 3.1% of 9th Grade students and 2.9% of 11th Grade students understood classification of animals and plants. There was a significant difference at the level of students' understanding of classification of animals and plants according to schools and gender(P<0.05). Students classified animals and plants through personal experiences and observations instead of trying to classify through microscopic analysis of animals and plants cell. 3. 1.2% of 7th Grade students, 10.3% of 9th Grade students and 19.4% of 11th Grade students understood food production in plants. There was a significant difference at the level of students' understanding of food production in plants according to schools and gender(P<0.05). Students had a misconception that food production in plants was done by an absorption of nutrients from soil not by photosynthesis. 4. A large proportion of teachers surveyed in this study appear to have misconceptions about homeostasis (38.1%), classification of animals and plants (34.1%), food production in plants (40.4%). The male teachers had. more misconceptions than female teachers(P<0.05). However, they didn't show any significant differences according to schools and teaching experience(P<0.05). 5. According to the investigation of teachers' perception, 29.8% of the teachers acknowledged that they might be a cause for students' misconceptions. This study shows that 38.3% of teachers did not understand the analyzed biological concepts precisely. By comparing the data of students and teachers, it turned out that teachers participate in the students' misconceptions. And teachers themselves acknowledged that students' misconceptions could be caused by them. Therefore. teachers' right understanding of fundamental biological concepts should precede to students' biology education. New training programs for biology teachers seem to be urgent.
