A Developmental Study on Biological Curriculum and Teaching Materials for General High Schools in Kangwon Rural Areas
Cho, Hee-Hyung ;
Journal of The Korean Association For Science Education, volume 12, issue 2, 1992, Pages 1~18
The curriculum especially in Korea plays a crucial role in developing instructional materials. It serves as a criterion for selecting and organizing content of teaching materials. Therefore, the validity of a curriculum can be justified through testing effectiveness of an instructional material developed in accordance with the curriculum. This paper presents an instructional method and material developed based on the current tendency of educational thoughts that emphasize STS and students - centered teaching strategies in science education. The instructional material was organized around the concept and its subconcept of "nutrition" as presented in the high school biology textbooks now in use in the nation as well as in a few world-wide countries. It was also organized by the use of biological events and phenomena which high school students in rural areas can easily encounter through their everyday lives. The significant findings in this study are :
The achievement levels in experimental groups were higher than one in controlled groups.
The students as well as the teachers involved in this study showed positive attitude toward the instructional method developed in the process of this study.
The greater part of the students among the controlled groups hoped that biology would be taught by this kind of teaching procedure and materials.
A Comparative Discussion on the Instructional Procedure and Strategies in Learning Scientific Concepts
Kwon, Jae-Sool ;
Journal of The Korean Association For Science Education, volume 12, issue 2, 1992, Pages 19~29
In this study, five learning models were compared and discussed in terms of their learning procedures and learning strateies. After a brief introduction of each model, the author discussed the differences and similarities among the five learning models. As a result, Kwon's procedual learning (Kwon, 1989) seemed to encompass almost all the learning models proposed by the other four author. All the models emphasized the importance of cognitive conflict. However, I. K.Kim(1991), Park(1992) and Y.M.Kim(1991) seemed to be concentrated their attention on the cognitive conflict between concepts ; while Hashweh and Kwon emphasized cognitive conflict between cognitive structure and environment. The study also suggested more study on the empirical evidence of the three kinds of the cognitive conflicts proposed by Kwon(1989) and on the development of learning strategies to induce and overcome the cognitive conflicts.

The purposes of this study were to find out the degree of formation of the concept of density for the junior high students. The changing pattern of concept in acquiring the concept of density and the degree of development of INRC transformation ability related to the concept of density were also analyzed according to cognitive level and teaching method. The results of this study were as follows. 1) The experimental group were more effective than control group in the formation of the concept of density. 2) Even though students had been taught the concept of density, the various types of preconception were remained and persisted. Especially, the students at concrete level had persisted misconceptions and these misconceptions had been changed to the other misconceptions. 3) In the degree of the formation of the transformation ability of INRC group related to the concept of density in solid phase, the experimental group developed much better on both the abilities of Reciprocal transformation, Correlative transformation and the abilities to manipulate two variables such as volume and mass than control group. 4) The correlation coefficient between GALT score and achivement of the concept of density was 0.67. The correlation coefficient between achivement of the concept of density and the formation the transformation of INRC group related to the concept of density was 0.78.

The purpose of this study was to investigate children's(K-5) conceptions about light in Korea. The two aspect of children's conceptions about light were identified : the sources of light, the nature of vision. Data were collected from 92 children by a mixture of writing, drawing and interview, and were analysed by systematic networks. The major findings of this study were as follows : 1. Children showed an awareness of a wide variety of sources of light. The predominant sources exampled by children were primary sources. 2. Children explained vision as intentional activity of seeing Seeing. means action that move their heal or eyes to the objects. Infants(K-1) did not recognize that light are needed for vision. 3. A notable features in children's conceptions about light were context-dependent.
The Acid-Base-Concepts of Korean Secondary Students
Kim, Hwa-Sook ;
Journal of The Korean Association For Science Education, volume 12, issue 2, 1992, Pages 55~65
The purpose of the study is to compare the learning contents of theme acids and bases that are commonly dealed with in elementary, middle and high schools m Korea and to investigate the acid-base-concepts of secondary students. The results of the study were as follows: 1) Many students did not have an interest in the chemistry and they pointed out the necessity of many experiments and practices and its application to the practical life. 2) It is found that most of textbooks used in the elementary school are written to make the students have an interest in the science through the experiments and pratices. However the textbooks used in the secondary school are too theoretically written so that many students are likely to lose the interests in the chemistry. 3) Although students had already learned Arrhenius's acid-base-concept, many students tried to solve the question with Liebig's theory as a acid-base-concept. This misconception might be caused by learning by cramming and teaching too theoretically. Accordingly, it is necessary that the education of science is carried out to make the students have an interest in the science by providing the students with the much more experiments and practices and also applying it to the practical life.

Journal of The Korean Association For Science Education, volume 12, issue 2, 1992, Pages 97~107
ln this study, we analyzed 5 science textbooks currently used for the 7th graders quantitatively by using the science textbook rating system of Collette and Chiappetta(1986), making meta-analysis of the results of 17 graduate school students of Seoul National University. The rating system consists of 11 categories with detailed items respectively : content, organization, reading level, instruction approach, illustrations, end-chapter teaching aids, laboratory activities in text and/or accompanying manual, teacher aids, indices and glossaries and mechanical makeup of text. Each item in the checklist is to be given between one and five points and the total number of possible points in this rating system is 290. It was shown that 5 science textbooks currently used for 7th-year-students were all "poor" in terms of total points and had, at large, uniformed results especially in 10 items; 7 items concerning moral and ethical implications of science, vocabulary lists, accompanying laboratory manual, annotated editions for test, supply list for laboratory program, student workbook and glossary with low points, while 3 items concerning facilities needed for laboratory activities, activities relevant to the content and textbook size with high points. A Science teachers could get a broad view with a correct impression of the books usefulness in making an evaluation of available textbooks.

Elementary science textbooks are the major instructional materials which contain sceientific objectives to be acquired by students. The purpose of this study is to analyze the development system, to evaluate the inquiry activity in current elementary science testbooks, and to make suggestions for the improvement of them. The questionnaires were administered to 116 subjects that participated in development of the 5th elementary science textbooks, and 86 of the subjects responded. Based on the data gathered and analyzed in this study, the major findings are as follows. First, regarding the analysis and evaluation of elementary science textbooks. 1. The instructional objectives in elementary science textbooks are analyzed. The proportions of comprehension objectives is 38%, scientific inquiry process objectives 21%, experimental skills objectives 7%, scientific attitudes and interests objectives 4%. 2. The science concepts in elementary science textbooks of the 3rd grade required the preconcrete operational level(82%) and of the 6rd grade required the postconcrete operational level (73%) by J. Piaget 3. The inquiry activities in elementary science textbooks are emphasizing gathering and organizing results and evaluation, and hypothesizing and designing an experiment Inquiry index of the elementary science textbooks is 76. This is significantly higher than 35
50 of America and U.K.. 4. The number of questions per class hour is mostly three, and most of them require the students to explain phenomena in nature or in experiment Second, regarding the development system of elementary science textbooks. 1. The budget for and the period of the development of elementary science textbook should be expanded. 2. For the improvement of elementary science textbooks, more abundant resources and time should be used for the basic study and the field trial of textbooks. 3. The elementary science textbook must include the affective objectives as well as the scientific knowledges and scientific inquiry skills. 4. It is not desirable to assign equal number of pages to the content of physics, chemistry, biology, and earth science. 5. Closer cooperation system is needed among the ministry of education, development research center and the field trial schools.
