An Analysis of Multi-dimension of Students' Interest in Learning Physics
Im, Sung-Min ; Pak, Sung-Jae ;
Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 491~504
Recent research has shown that students' interest in learning physics is not a simple one. In this study the dimensions of students' interest in learning physics have been identified. These are the topic being taught, the activity in which the students are involved, and the motive of the students for learning physics. A Likert-style pilot questionnaire was constructed for identifying these dimensions and given to 13 year-old 162 students. A factor analysis of the results indicates that there are meaningful sub-dimensions in interest. In other words, while there were no specific sub-dimensions in topic dimension, motive dimension could be divided into intrinsic motive and extrinsic motive, and activity dimension could also be divided into receptive, experiential, high cognitive, and interactive activity.

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 505~509
The kinetic structure of the content of instructions at the unit of 'heart and circulation' in "the common science", which was respectively given by two teachers majored in biology and two teachers majored in earth science was investigated. Concerning of the mean of the fundamental coefficient (B1), the mean of weighted coefficients (B2) and the progression of instruction (P), T4 (B1, 0.14; B2, 0.82; P; 0.86) teacher showed relatively lower kinetic structure and faster progression than those of the others. The other teachers showed a different level of the kinetic structure and progression: T1(B1, 0.21; B2, 0.86; P; 0.79), T2 (B1, 0.02; B2, 0.85; P; 0.80), and T3 (B1, 0.22; B2, 0.83; P; 0.78). T1 teacher who showed the largest total frequency of verbal elements, the great number of sorts of verbal elements and secondary span, had a higher level of the kinetic structure, but T4 teacher showed the lowest level of total frequency of verbal elements, the great number of sorts of verbal elements and secondary span. The main reason why T4 teacher's instruction achieved a lower level of kinetic structure was estimated that he neglected to reorganize teaching materials and he showed a small number of discourse units. In addition, the unit of 'heart and circulation' was less related to T4 teacher's major and T4 teacher had a shorter teaching experience than those of the others. T4 teacher also took charge of only one class, and this did not allow to instruct repeatedly.

Choi, Kyung-hee ; Cho, Hee-Hyung ; Kim, Dai-Shik ; Kim, Sung-Won ;
Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 510~518
The purpose of this study was to develop learning materials for the discussion and examine the effects of the discussion learning over the students' conceptual change on force and motion. The subjects consisted of 360 middle school students, comprising of 5 discussion groups of 185 students and 5 traditional learning groups of 175 students. The results indicated that students in the discussion groups showed higher achievement than those in the traditional learning groups. Therefore this study supported the importance of discussion in conceptual change. However further research should be conducted to examine other educational effects of discussion.

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 519~526
In this study, the effects of visual organization and cooperative learning in problem-solving strategy were investigated. Three classes (N=127) at a high school were assigned to SV (Strategy-Visual organization) group, SVC (Strategy-Visual organization-Cooperative learning) group, and control group. After instructions, students' multiple-choice problem-solving ability, strategy performing ability, anxiety about chemistry learning, perception of involvement, and motivation to learning science were examined. Although multiple-choice problem-solving ability was not different significantly, there was a significant main effect in strategy performing ability. The scores of the SV and SVC groups were significantly higher than those of the control group, especially in the subcategories of problem understanding and recalling related principles. In the tests of perception of involvement and motivation to learning science, the scores of the SV and SVC groups were also significantly higher than those of the control group. However, problem-solving strategy using visual organization could not alleviate anxiety about chemistry learning.

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 527~541
The purpose of this study was to find out the characteristics of learning contents structure of K-12 science textbooks. The characteristics are related to 7 main concepts of matter properties; reaction rate, other reaction, density, solution, state change, absorption, and surface property. The contects are analyzed into 5 types of characteristics; type of concept extension, type of concept deepness, type of same level concept, type of confusion with other concepts, and type of concept interruption. First two types are positive content structures, but the others are negative structures. The findings are as follows. First, a lot of learning contents have the characteristic of 'type of same level concept'. There are few which have the characteristic of 'type of concept deepness'. Second, there are a lot of concepts related to 'properties of matter' which are not represented any more in middle and high school science textbooks. Those concepts are importantly taught in early childhood education and elementary school science. Most of the learning contents don't represent 'type of concept deepness'. Therefore the science textbooks needs to be restructuring.
An Investigation of the Relationships among College Backgrounds in Science, Attitudes toward Teaching Science, Science Teaching Self-Efficacy Beliefs, and Instructional Strategies of Elementary School Teachers (I) - Based on a Quantitative Data Analysis -
Park, Sung-Hye ;
Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 542~561
The purpose of this study was to investigate the relationships among elementary school teachers' high school and college backgrounds in science, their attitudes toward teaching science, their science teaching efficacy beliefs, and their instructional strategies. Both quantitative and qualitative research methodologies, were utilized in this study. This paper, however, presents only the results of the quantitative data analysis while expecting to report the qualitative data analysis outcomes afterwards. Four instruments were used to ascertain information concerning teachers' backgrounds in science(the number of high school science courses they took and the grades of courses, the number of college science courses and grades, the number of college science methods courses and grades), attitudes toward teaching science, science teaching self-efficacy beliefs(personal science teaching efficacy and science teaching outcome expectancy), and their instructional strategies(indirect, direct, and mixed methods). A sample of 340 practicing elementary school teachers participated in this study. To determine statistically significant results, Pearson's correlation coefficient was used to relate teachers' backgrounds in science, attitudes toward teaching science, science teaching self-efficacy beliefs and their instructional strategies. The correlation coefficients were statistically significant regarding four variables, teachers' backgrounds in science, attitudes toward teaching science, science teaching self-efficacy beliefs, and instructional strategies investigated in this study. These results can be interpreted that programs of teacher preparations and trainings which include science and science methods courses should help prospective and practicing teachers change in their attitudes and beliefs toward science teaching. It is expected that future studies concerning teachers' attitudes, beliefs, and behaviors toward teaching science can help to improve science teacher education in Korea.

Practical research, as well as theoretical research, about performance assessment is important for the successful application of performance assessment in school. To do this, two school teachers with professional educators studied theoretical basics of performance assessment for several months. As a result, 4 categories of issues for designing performance assessment were generated and described by teachers. Based on those issues, 5 directions for development were established, and finally, 7 types of performance assessment were developed. Developed items were disseminated to other two middle school teachers for application in school. After application during several months, interviews with them were conducted to obtain the informations and implications about the practical application of performance assessment.

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 572~581
Teachers' perceptions about curricular objectives are very important to achieve given educational objectives. This study examined teachers' perceptions about priority and hinderance of science objectives. The national science curriculum stated four areas of objectives: inquiry, knowledge, attitude, and STS. A total of 76 elementary and 217 secondary teachers were responded to questionnaire developed for this study. Non-parametric statistics, such as Friedman test, Kruskal-Wallis test, and chi-square test were used by using SPSS/PC program. Teachers in general ranked the inquiry first among the four areas at their perception on the national curriculum, on themselves, and on their instructions. Elementary teachers ranked inquiry higher than secondary science teachers, while secondary science teachers ranked knowledge higher than elementary teachers. As factors hindering teachers from achiving the objectives, elementary teachers pointed out overcrowded classroom and secondary science teachers pointed out college and university entrance examination respectively.
Development of a Value Inquiry Model in Biology Education

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 582~598
There are many bioethical issues in line with the rapid advance of biology. In this situation, it is important for students to make a rational decision on value problem. In this study 'value inquiry in biology education' is defined as 'the process of rational value judgement and wise decision-making in the biology-related value problem' and the model was developed. To develop the model, value inquiry models were reviewed. Value clarification model is helpful for the formation of the personal value as the process of individual value inquiry, but it isn't helpful for clarifying the value conflicts. Value analysis model focuses on the rational solution of value problem through the logical procedure. But it has the limitations that overemphasizing the logical and systematic aspects results in devaluating students' affective aspects. So it is necessary to coordinate psychological and logical aspects of value inquiry. In this regard, the model was developed, including identifying and clarifying value problem, understanding biological knowledge related to conflict situation, considering on the related persons, searching for alternatives, predicting the consequences of each alternative, selecting the alternative, evaluating the alternative, and final value judgement and affirming it. The educational objectives of value inquiry were selected in consideration of the ability to carry out the steps of the developed model. And the selected contents were animal duplication, test-tube baby, genetic engineering, growth hormone injection problem, brain death, organ transplant, animal to be experimented and were organized on the basis of the 6th and the 7th science curriculum. And the suitable instructional models for the value inquiry education were selected: bioethical value clarification decision-making model, group presentation according to the value analysis model, role play and debate, and discussion through web forum. And the interview was considered to be suitable to evaluate the students' value inquiry ability and the rubric was made to evaluate the attainment of the educational objectives for value inquiry.

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 599~610
In this study, a questionnaires survey was administered to Korean and Japanese junior high school science teachers in the capital area to investigate the extents of Science-Technology-Society(STS) education practiced in science classroom. The responses of 69 Korean teachers and 33 Japanese teachers were analysed. The results showed that most of teachers in both country knew well about the meaning and the purpose of STS education. Also they realized the needs of applying the STS education in science class and had wills to do it. However, only about a half of teachers - more than a half of Japanese and less than a half of Korean - were practicing the STS related subjects, activities and assessments in the class. Teachers in both country responded that their science textbooks did not contain enough amounts of STS related contents and other STS education materials available were not much. Therefore, it is needed to include more STS related contents in the science textbooks and to develop various STS education materials and circulate them as well as to establish adequate teaching and assessment methods for STS education. Also activating teachers' meetings to circulate the informations and materials and improving the school environments are recommended.

The cooperative learning movement began as parts of the desegregation process in America, aiming at increasing academic achievement and social skills among diverse students. Cooperative learning may be defined as a classroom learning environment in which students work together in small heterogeneous groups. Although many studies have shown the effectiveness of cooperative learning in a variety of subjects, relatively few have focused on biology. In this study, we investigated the effects of cooperative learning on students' achievement and attitude of middle school biology students. For this purpose this study compared three sections. In one section, a cooperative learning strategy was used. Second section was taught in small groups and the third section was instructed in the traditional method. The unit 'Structures and functions of animals' was used. A total of 188 students were included in this study. These classes were treated for 10hours during 10weeks from September 1 to November 28, 1999. The pretests-posttests control group design was applyed. An analysis of covariance(ANCOVA) was used as the data analysis procedure. Significant differences were found in the achievement and the attitude of students using cooperative learning strategy(p<.05) when compared to traditional classroom structure and small group learning. Cooperative learning was more effective in the low-ability and average-ability students than the high-ability students in the science achievement. Cooperative learning is effective in both male and female students. And students in the cooperative group achieved better than those in other groups in affective, behavioral, and intention-cognitive domain of science attitude.

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 624~633
This study investigated students' verbal behaviors in paired think-aloud problem solving. High school students in chemistry classes were asked to use 4 stage problem-solving strategy through paired think-aloud problem solving, and their small-group behaviors were audio/video taped. Verbal behaviors of the solvers and listeners were classified into 8 categories. Solvers frequently exhibited the behaviors of 'require agreement', 'provide', and 'modify', and listeners frequently exhibited the behaviors of 'agree', 'ask', and 'point out'. With behaviors exhibited frequently, the verbal interaction between solvers and listeners were also investigated. In studying partial correlation between verbal behaviors and the improvement of problem-solving ability, listener's 'agree' and 'point out', and solver's 'modify' were positively related with listener's improvement. However, there was negative correlation between listener's 'point out' and solver's improvement. In a perception questionnaire, many students were found to perceive that the paired think-aloud problem solving helped them to be aware of the problem-solving processes. However, some listeners also perceived that it was difficult to know solver's problem-solving processes.

The degree of cognitive conflict, conceptual change, and the retention of conception in studying 'the cause of rising water at burning a candle in a bottle' with anomalous data were compared by age and gender. According to 'change of belief in initial theory', 7 types of responses to anomalous data were ordered by 4 levels. In comparing the results by age, producing cognitive conflict by anomalous data, conceptual change, and the retention of conception were found to be more effective for older students than younger students. However, the degree of cognitive conflict was not significantly correlated with the conception and retention tests scores. The results of Mann-Whitney U test revealed that there were no significant differences by gender in the degree of cognitive conflict, conceptual change, and the retention of conception.

Choi, Kyung-Hee ; Cho, Hee-Hyung ; Kim, Ji-Hyun ;
Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 642~651
The purpose of this study was to examine the effect of teaching science ethical issues relevant to the middle school science curriculum. The experimental subjects were 132 second grade middle school students in Seoul, who were divided into two groups without any statistical differences. The results of this study indicated that teaching ethical issues in science had a positive influence on students' attitudes toward science and fostered a positive impression of science education. Also, the students showed a positive attitude in dealing with ethical problems in science and technology. Regardless, the results of this study suggest that ethical education in science classes is effective in increasing positive attitude toward science and the ability of the students in addressing and resolving ethical problems in science and technology. As such, we strongly recommend that the science curriculum for middle school students be changed to integrate ethical issues in the science class.

Lee, Wha-Kuk ;
Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 652~666
The purpose of this study is to analyze high school chemistry curricula in Korea and China in order to identify possible implications for the improvement of the Korean curriculum. The school curricula of Korea and China had been developed by the Ministry of Education of both countries as national curricula. The 1996 Chinese high school chemistry curriculum, and the 7th Korean high school chemistry curriculum announced in 1997 were compared in respect to the characters, objectives, history, time allotment, structure, subject contents, and assessment plans. Based on the comparative analysis of the curricula, some of the ideas, which provide implications for the improvement of Korean chemistry curriculum, were identified. The identified ideas were elaborated to seek directions for the solutions of current problems in chemistry curriculum. such as common science subject. tentative implementation of curriculum, compulsory provision of chemistry, subjects in science course, enlargement of curriculum, and methods of assessment.

Park, Jong-Won ;
Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 667~679
One of the major activities in scientific inquiry, as well as in the process of conceptual change, is the generation of scientific hypothesis. In this study, the definition and the characteristics of scientific hypothesis are analyzed. Especially, differences between explanatory hypothesis and scientific explanation, predictive hypothesis and scientific prediction, and scientific hypothesis and the inductive generalization are analyzed. And the process of making scientific hypothesis is suggested as 4 stages, and the role and the characteristic of the abductive thinking, which can be viewed as one of the scientific inferences needed to generate hypothesis, are discussed. In analysis, concrete examples from integrated science textbook of high school are used for application to the classroom teaching.

Journal of The Korean Association For Science Education, volume 20, issue 4, 2000, Pages 680~692
An assessment instrument dealing with secondary students' views on the nature of science was developed in this study. The features in aspects of the nature of science are generally accepted as characterizing the scientific enterprise and we have focused on are: 1) the purposes of the scientific enterprise, 2) the nature of scientific enquiry, 3) the nature and status of scientific knowledge, and 4) the nature and functioning of the scientific community. The questionnaire is made of three sections; that is, "Scientific Question", "Experiment", and "Belief". The Scientific Questions probe was designed to examine the ways in which learners mark out science as a particular domain, and particularly the types of questions that they think are open to scientific investigation. The Experiment probe was designed to throw light on the ways in which learners may think about theories and their relationship to evidence in a range of contexts. A related aim concerns the sorts of activities that learners consider to be experiments, and their reasons for this. The Belief probe was designed to see whether students are able to articulate the grounds for their acceptance of a proposition and, if they are, to explore the nature of these grounds. The reliability of the instrument developed in this study was found to be 0.86.
