Grade Students, Pre-service Teachers and Science Teachers' Views on the Dissolution of Salt in a Liquid
Won, Jeong-Ae ; Kang, Dae-Hun ; Paik, Seoung-Hey ;

In this study, a survey was conducted of students in grades 7 through 12, student teachers enrolled in their senior year at teachers' colleges, and science teachers. Subjects were surveyed on their conceptions of phenomenon related with dissolution, saturation, and extraction. The models and analogies used by student teachers and science teachers to explain dissolution were sought. The highest percentage of students thought of dissolution as a phenomenon in which particles broke into the spaces between other particles. The models or analogies used by the highest percentage of science teachers were similar. They generally conceived of dissolution phenomenon through what we call the 'space conception'. A conception of dissolution phenomenon as 'hydration through attraction of solvent and solute' was held by more student teachers than science teachers; there were some differences, however, according to their academic background. The percentage of teachers professing this view decreased when they attempted to explain the process of extraction of matter in a solution after other matter had dissolved or after the solution was cooled, indicating that the 'hydration' conception was not firmly established in the student teachers' cognition. Therefore, it can be inferred that the conceptions of dissolution as 'hydration' were transformed into the conceptions of dissolution as 'space' after teaching dissolution phenomenon as practicing teachers. This finding should be considered in teacher-training courses.
Cases and Features of Abductive Inference Conducted by a Young Child to Explain Natural Phenomena in Everyday Life
Joung, Yong-Jae ;
Journal of The Korean Association For Science Education, volume 28, issue 3, 2008, Pages 197~210
The purpose of this study is to explore the cases and features of the abductive inference used by young children when trying to explain natural phenomena in everyday life. From observing a 5-year-old's daily activities with his family, and analyzing the data according to the criterion extracted from the form of abductive inference described by C. S. Peirce, a few cases where the child used abductive inferences to explain natural phenomena were found. The abductive inferences in the cases were conducted: (a) based on figural resemblance and behavioral resemblance (b) under the influence by individual belief and communal belief, then (c) resulted in new categorization accompanied by over generalization. Such features of the abductive inference showed the 'double faces'; sometimes encourages and sometimes discourages children's generating better scientific hypotheses and explanations. These results suggest that even young children use abductive inference to explain doubtful natural phenomena in everyday life, although we need to consider carefully with the double aspects of the features of abductive inference for the practical applications to the fields of science education. Finally, several suggestions and following studies for science education are proposed.
Analyzing Science Teachers' Understandings about Scientific Argumentation in terms of Scientific Inquiry
Park, Young-Shin ;
Journal of The Korean Association For Science Education, volume 28, issue 3, 2008, Pages 211~226
The purpose of this study was to investigate science teachers' understandings about scientific argumentation in the classroom. Seven structured interview protocols were developed, asking the definition of scientific inquiry, the differentiation between scientific inquiry and hands-on activity, the opportunity of student argumentation, explicit teaching strategies for scientific argumentation, the critical example of argumentation, the criteria of successful argumentation, and the barrier of developing argumentation. The results indicate that there are differences and similarities in understandings about scientific argumentation between two groups of middle school teachers and upper elementary. Basically, teachers at middle school define scientific inquiry as the opportunity of practicing reasoning skills through argumentation, while teachers at upper elementary define it as the more opportunities of practicing procedural skills through experiments rather than of developing argumentation. Teachers in both groups have implemented a teaching strategy called "Claim-Evidence Approach," for the purpose of providing students with more opportunities to develop arguments. Students' misconception, limited scientific knowledge and perception about inquiry as a cycle without the opportunity of using reasoning skills were considered as barriers for implementing authentic scientific inquiry in the classroom.
Assessment of Students' Cognitive Conflicts and Anxiety

Cognitive conflict is well recognized as an important factor in conceptual change and is widely used in developing constructivism-based curricula. However, cognitive conflicts can also contribute to student anxiety during learning, which, when not properly addressed, can have negative impacts on students' motivation and achievement. Therefore, instructors need to be aware of the impacts of introducing cognitive conflicts in their instruction. We need a practical instrument that can help identify the existence and features of cognitive conflicts introduced by the instruction and the resulting anxiety. Based on the literature on studies of cognitive conflicts and student anxiety, we developed a quantitative instrument, the In-class Conflict and Anxiety Recognition Evaluation (iCARE), and used it to monitor the status of students' cognitive conflicts and anxiety in Physics by Inquiry (PBI) classes. In this paper, we introduce this instrument and present the types of information that can be obtained. Research and pedagogical values of this instrument are also discussed.
Perception of the Scientifically Gifted and Long-term Effects of Science Gifted Education Program - from the Students' Perspectives

Journal of The Korean Association For Science Education, volume 28, issue 3, 2008, Pages 241~252
The purpose of this study is to investigate the impacts of a science gifted education program. 155 students who experienced the SNU science gifted education program were interviewed. The interview questions consisted of eligible questions from 'Interview Protocol of Hertzog' (2003) based on 'Recommended Practice in Gifted Education (Shore, Cornell, & Ward, 1991)'. All interviews were immediately transcribed and analyzed qualitatively. It was found that scientifically gifted students had similar concepts of the gifted to what scholars consider as the gifted. Comparing the programs to school education program, the students agreed that the science gifted education program provided more experiments opportunities, higher and deeper level of contents, and more active interactions. Regarding long-term effects, it was found that program influenced on students' decisions for the future, stimuli and expansion of horizons, school work and entrance examinations. Students gained self-confidence and became more interested in science. Some pointed out that they felt greater stimulated, although some indicated an elevated level of self conceit. Implications of science gifted education were found based on these results.
Articulating Science Teachers' Values and Convictions for Teaching Socioscientific Issues: Based on Essentialist Methodology
Lee, Hyun-Ju ;
Journal of The Korean Association For Science Education, volume 28, issue 3, 2008, Pages 253~268
This paper has two major purposes. One is to introduce the essentialist methodology as a way to articulate subjective aspects of human beings (e.g. teachers' personal values and concerns, philosophies, subjective experiences, etc.) at a deeper level. And the other is to present two portraits, as examples, of science teachers who actively address socioscientiifc issues (SSI) out of their own motivations. The primary data source was consecutive in-depth interviews with two science teachers, Jenna and Thomas, and the interviews were conducted on the basis of the principle of the "participant as ally" (Witz, 2006). The articulation based on the essentialist methodology shows that teachers' deep-rooted values and convictions often play a significant role as a personal social capital enough to expand their teaching practice (i.e. teaching SSI). Namely, this study confirms that teachers who are motivated out of their own convictions are likely to actively develop their own personal practical knowledge, and to implement particular topics or teaching strategies.
