Journal of The Korean Association For Science Education, volume 27, issue 9, 2007, Pages 765~777
Investigations into how the status of prior learning on the textbook of science were conducted, and the effects of prior learning on students' attitudes towards science class were carried out. The investigations for the status of prior learning were performed with a number of students who experienced prior learning, (self-directed and unself-directed prior learning), a selfless intention as the starting motive for prior learning, the problem solving strategies used by students in prior learning, and the important factor that influenced prior learning. The effects of prior learning on student attitude towards science class were also examined with respect to four categories, including confidence, interest, learning intention, and value (effect). The effects of prior learning on the four categories were analyzed on the basis of the students' level of scientific achievement, the types of prior learning, the starting motive for prior learning, and the extent of the students' understanding of the content on prior learning. The analytical results for the effects of prior learning on students' attitudes towards science class showed that the mean values of confidence, learning intention, and value among the students in the self-directed prior learning group were higher than those of the students in the unself-directed prior learning group. These findings are the result of positive recognition, such as the possibility that the students experienced with self-directed prior learning can do, the induction of an inherent motive based on their level of achievement in science class, and the operant learning of strategies for solving problems in science class. Meanwhile, by the effects of having a teacher lead the science class and the consensus formed between friends, the mean level of interest was higher in the unself-directed prior learning than in the self-directed prior learning.

This study investigated the effects of analyzing mapping errors on conceptual understanding, mapping understanding and perceptions of the instructions in learning chemistry concept with analogy. Seventh graders (N=121) at two middle schools were assigned to the comparison and the treatment groups, and were taught about 'states of matter and arrangement of molecules.' The students in the comparison group were taught in the Teaching-With-Analogy (TWA) model, while those in the treatment group Were taught in the instructional model that changed 'mapping similarity' and 'indicating difference' of the TWA model into 'analyzing mapping errors.' Analysis of the results revealed that the scores of the conception test and the mapping test for the treatment group were significantly higher than those far the comparison group regardless of field dependence-independence. It was also found that most students in the two groups positively perceived the instructions with analogy, but the students in the treatment group had difficulties in analyzing mapping errors, Educational implications are discussed.

The purpose of this study was to examine the effects of experimental learning using Small-Scale Chemistry (SSC) on science achievement and scientific attitude of high school students. SSC experiments were devised for 5 experiment themes of high school science textbook. Two classes were chosen from a high school in Busan and adopted into the comparison group and the experimental group; one group with thirty-four students participated in the class with an experimental learning using the SSC (experimental group), and another group with thirty-seven students participated in the class with the traditional learning (comparison group). The major discoveries of this study were as follows: Experimental learning using SSC has shown a significant difference between two groups in the science achievement of the students. Also there was a statistical difference between these two groups in the test which was conducted after a month to find out the durability of the experiment. Thus, the learning using SSC is assumed to be durable. Furthermore, there was a significant difference in scientific attitude between the two groups. It seemed that the learning using SSC had a good influence on fanning students' scientific attitude. In conclusion, an experimental learning using SSC has a positive effect on scientific achievement, the durability and scientific attitude of the students. We hope to develop suitable and various experimental learning materials using the SSC program that can be adopted in the classroom soon.

There are various definitions of Science Culture nowadays. In this study we redefine Science Culture as a union between Science and Culture. We also develop the Framework of Science Culture Indicator (FSCI). which consists of five fields; History of Science, Philosophy of Science, Literature and Art of Science, Scientific Social Activity and Scientific Media. In this study we also investigated the level of the Science Culture of secondary school teachers, and compare them by teachers' majors: Science, Liberal Arts and Social Studies. To analyze the data, the Kruskal-Wallis Test is adopted. It is found that there are significant differences in the level of Science Culture by teachers' major, and the group of science teachers has the highest level of science culture.

The purpose of this research was to investigate the nature of the science views of science teachers and high school students as well as the views expressed in 10th grade science textbooks. The subjects were a high school science teacher, 18 male students and 11 female students in a 10th grade class located in Gyeongbuk Province, Korea. The data were analyzed in terms of three main categories of the nature of the science: the definition of science, the development of science, and the method of science. In the results, it was found that the textbook had an inductivism point of view, and that the teacher had a falsificationism point of view in terms of the definition of science. However, the teacher presented the inductive point of view of the textbook in the class. After the class, the students showed an inductive point of view. In terms of scientific development, the textbook represented a relativism point of view briefly, and the viewpoint of the teacher also expressed relativism. The teacher taught briefly from the relativism point of view, as in the textbook. The viewpoints of the students were inductivism and were not affected by the textbook or the explanations of the teacher. In terms of scientific methods, the viewpoints of the textbook and the teacher were falsificationism, and the teacher represented falsificationism views in her classes. The views of the students also showed falsificationism after their classes. However, before conclusions can be made, it is necessary to find concrete proof of the teaching effect on the viewpoints of the students in continuing research.

Recognizing the importance of abductive inquiry in Earth science, some theoretical approaches that deploy abduction have been researched. And, it is necessary that the abductive inquiry in a geological field excursion as a vivid locale of Earth science inquiry should be researched. We developed a geological field trip based on the abductive learning model, and investigated students' abductive inference, thinking strategies used in those inferences, and the impact of a teacher's pedagogical intervention on students' abductive inference. Results showed that students, during the field excursion, could accomplish abductive inference about rock identification, process of different rock generation, joints generation in metamorpa?ic rocks, and terrains at the field trip area. They also used various thinking strategies in finding appropriate rules to construe the facts observed at outcrops. This means that it is significant for the enhancement of abductive reasoning skills that students experience such inquiries as scientists do. In addition, a teacher's pedagogical interventions didn't ensure the content of students' inference while they helped students perform abductive reasoning and guided their use of specific thinking strategies. Students had found reasoning rules to explain the 01: served facts from their wrong prior knowledge. Therefore, during a geological field excursion, teachers need to provide students with proper background knowledge and information in order that students can reason rues for persuasive abductive inference, and construe the geological features of the field trip area by the establishment of appropriate hypotheses.

The purpose of the study was to analyze and interpret parent-child dyadic discourses in depth with emphases on the ZPD system in a museum, an informal learning setting. Second graders and their parents from Seoul and its environs were voluntarily participated in the study. Data were collected from the museum documents, the photos of exhibits, and the video recordings of dyadic discourses at and between exhibits. The documents and the photos were analyzed to investigate what the topics, medium and goals of the exhibits were. The video recordings were all transcribed and analyzed to understand what and how they talked to each other through the lens of the ZPD system; situation definition, intersubjectivity, and semiotic mediation, The results of the study consisted of two parts. First, it showed that parent-child dyadic discourses were categorized in four: (1) within the actual developmental level; (2) in the zone of proximal development; (3) toward the potential developmental level; and (4) out of developmental level. The most common categories were the dyadic discourses within the actual developmental level and in the zone of proxima I development. Second, the representative cases in each categories were described and interpreted to understand the nature of parent-child dyadic discourses. It can be concluded that we gained some important understandings of an intrinsic attribute of parent-child discourses in a museum, an informal learning setting. Based on the results of the study, it can be suggested that museums make efforts to cultivate the affordance of exhibit environment to promote visitor's learning.

The purpose of this study was to investigate the relationships among scientifically gifted students' science related attitudes, learning motivation and learning strategy. Subjects were 135 middle school students enrolled at a Center for Science Gifted and Talented Education. There was no difference among talented divisions according to science related attitudes. But the score of the female students were higher than that of the male in learning motivation and learning strategy. Some significant correlation coefficients were between learning motivation and learning strategy. Also significant correlation coefficients were among 'career interest in science' domain, 'leisure interest in science' and 'social implication of science.'

In this study, we investigated secondary science teachers' internalization of constructivistic science teaching who participated in a collaborative program between teachers and researchers designed by researchers according to constructivist views. The program consisted of lecture, workshop, and small group activities. New trends in science education and framework for science teaching were introduced during lectures, and understanding about the framework were deepened by analyzing school science classes recorded during workshops. In small group activities, participating teachers and researchers cooperated to design science lesson plans using science teaching frameworks. Five secondary science teachers participated in collaborative workshops. Collaborative programs were video-taped. Semi-structured interviews were conducted before and after workshops. All data recorded were transcribed and analyzed. In the process of internalization, participating teachers attended on different parts. Various and discernable factors such as there own background, beliefs, values, and school context produced tensions with or facilitated internalization of constructivistic science teaching. Teaching experiences and student understanding affected teachers' lesson planning activities. Teachers also showed different understandings on inquiry, application, and model from the framework, and they interpret those concepts in the framework based on their prior understanding. They perceived that too much content should be dealt within relatively limited time. Therefore, they tended to separate science class into two parts when developing science lessons: explaining science content by lecture and science laboratory as a constructivistic activity. The results of the study provide meaningful implications to the constructivist teacher education and professional development.

The purpose of this study was to understand the change and characteristics of interactions in a heterogeneous group in scientific inquiry experiments. For this purpose, the process of students' interactions in small group activities were analyzed. This study focused on two, small heterogeneous groups of eighth graders. Students were involved in 13 scientific inquiry experiments for one year and students' interactions in each experiments were observed and recorded using video/audio and the data recorded were transcribed. The analysis of data was based on the method of making a note by looking and listening to the data repeatedly. Students' interactions in heterogeneous group changed toward that 3A (early formal operation student solved the problems by oneself and other students only listened to 3A student's explanation or copied the answer. The least able student was alienated from peers' interactions. In the meantime, new interactions of two middle level students were shaped. Educational implications of the progression of activities emphasizing interactions and the organization of grouping were drawn.

This study is aimed to classify teachers' questions and feedbacks as well as students' responses in term, of type and frequency, and speculate the distinctive features of verbal interactions including teachers' questions and feedbacks performed actively in the classes of the gifted in science. The 24 hours of the classes made for the 8th grade science-gifted students were observed and recorded. In addition, the mutual conversations between the teacher and the students were transcribed and analyzed, and the interviews with the teachers also were made. It is found that the teachers usually use the question methods of memory recollection, perception and memorization, together with an instant feedback method, while the students prefer to respond with rather short answers. The characteristic features of the class by the teachers who lead the active class show that they use the open questions at the beginning, raise the level of the questioning, use the questions 'why and how' frequently, and to ask evaluative questions. Their feedbacks to the students interestingly indicate that they show the students the attitude of accepting and receiving students' replies, invite different responses from other students by reserving instant answers or judgements to the students, and give the students the confidence of solving the next problems, by praising and encouraging them.

Journal of The Korean Association For Science Education, volume 27, issue 9, 2007, Pages 893~906
The purposes of this study are to understand pre-service science teachers' areas of practice concern and reflections on the science classes during student-teaching, and to grasp the factors affecting their concerns and reflections. Four pre-service science teachers participated in this study. Data were collected from four pre-service science teachers' practice journals, instructional materials, and semi-structured individual interviews after their student-teaching. The results are as follows: firstly, the pre-service teachers' concern is focused on the teaching environment and strategies, particularly classroom atmosphere and class management. On the other hand, they pay little attention to science content. Secondly, pre-service teachers' reflections are confined within the limited areas such as classroom management, the proper role as science teachers, or various teaching materials. The level of their reflections is low, mostly concentrated on 'routine' or 'technical' level. Higher levels of reflections, such as 'dialogic' or 'transformative' are not revealed at all. Thirdly, the mentor teachers have the biggest influence upon the concerns and reflections of pre-service teachers during student-teaching.

This study was conducted to explore key factors of expertise development of talented scientists who achieved outstanding research performance according to the stages of expertise development and dimensions of individual-domain-field. To fulfill the research purpose, 31 domestic scientists who were awarded major prizes in the field of science were interviewed in-depth from March to September, 2007. Stages of expertise development were analyzed in light of Csikszentmihalyi's IDFI (individual-domain-field interaction) model. Self-directed learning, multiple interests and finding strength, academic and liberal home environment, and meaningful encounter were major factors affecting expertise development in the exploration stage. In the beginner stage, independence, basic knowledge on major, and thirst for knowledge at university affected expertise development. Task commitment, finding flow, finding their field of interest and lifelong research topic, and mentor in formal education were the affecting factors in the competent stage. Finally, placing priority, communication skills, pioneering new domain, expansion of the domain, and evaluation and support system affected talented scientists' expertise development in the leading stage. The meaning of major patterns of expertise development were analyzed and described. Based on these analyses, educational implications for nurturing scientists were suggested.

Lee, Kyu-Bae ;
Journal of The Korean Association For Science Education, volume 27, issue 9, 2007, Pages 919~929
Some Korean terminologies related to the structures of vascular tissues in plant morphology, written differently depending upon textbooks and dictionaries, were analysed to propose properly expressed Korean terminologies. A total of 14 university textbooks such as general biology, plant biology, and plant morphology were selected and investigated. The terminologies on the xylem structures, i.e., apotracheal parenchyma, paratracheal parenchyma, tylose, and tangential (longitudinal) section; and on the pit structures i.e., simple pit, bordered pit, aspirated bordered pit, and pit aperture; and on the stelar structures, i.e., haplostele, actinostele, plectostele, and solenostele were examined. The definition and etymology of the terminologies were traced in 4 textbooks of plant anatomy and 2 dictionaries of biology and botany written in English. And then reasonably expressed Korean terminologies, mostly written in Chinese characters, were suggested. The terminologies were compared with those that appeared in the Iwanami dictionary of biology published in Japan. It was expected that the results would contribute to promote mutual understanding between teachers and students in learning plant biology.

Journal of The Korean Association For Science Education, volume 27, issue 9, 2007, Pages 930~943
The purpose of this study was to investigate if students may actually experience scientific reasoning based on an epistemology of authentic science during authentic open inquiry. The samples were 86 10th graders in a science-high school in Seoul. The experimental group practiced authentic open inquiry and the control group practiced traditional school science inquiry in five weeks. Then, the questions students asked while performing inquiry tasks were analyzed. The frequency of the questions asked by students was almost same between two groups, however, the types of questions were different. The frequency of thinking questions in experimental group was higher than the control, and the difference was statistically significant (P<.01). Particularly, the frequency of expansive thinking questions and anomaly detection questions was much higher in experimental than the control group. Judging from the result, with the students from the experimental group asking questions reflecting on the epistemology of authentic science such as scientific methods, anomalous data, and uncertainty about reasoning, students may understand authentic science features during the activities of open authentic inquiry. The result from comparing questions according to the inquiry subject showed that more openness caused the higher frequency of anomaly detection questions and strategy questions, but that inductive thinking questions and analogical thinking questions were connected to inquiry subject rather than the openness of the inquiry.
