Journal of The Korean Association For Science Education, volume 31, issue 5, 2011, Pages 663~679
This case study focused on three science teachers who participated in the Research Experience for Teachers (RET) program conducted by the Center for Bridging Advanced Science and Education (CBASE). The RET program provides opportunities for participants to experience experimentations in a science laboratory for six months, enabling teachers develop teaching materials based on their experience from the RET program. The purpose of this study was to explore how the teachers had developed their professionalism through participation in the program and which factors promoted the professional development of science teachers. In this research, we defined pedagogical content knowledge (PCK) as the required knowledge for teachers to develop for their professional development. As a result of the RET program, all three participants showed integration of PCK elements: orientation to teaching science, knowledge of science, knowledge of students, knowledge of teaching, and knowledge of sources. The PCK elements which had been developed by the RET program were applied in school context and the teachers' belief became clear and strong. The teachers were able to understand the process of authentic science as they learned it from 'legitimate peripheral participation' in the authentic research context. They also showed dynamic integration between newly established elements of PCK by reflecting on the school context while developing the teaching materials. The professional development of each teacher was different depending on the purpose and PCK, which participants had already possess. This study will provide meaningful implication for the development of professional development program for science teachers based on research experience.

In conceptual ecology, a concept does not exist independently but occupies an ecological niche in ecological environment. Among many biological concepts, genetic concepts are connected to several units including the genetics unit, and within the genetics unit the concepts of sub-areas are highly dependent on one another. For this reason, we analyzed conceptual diversity and conceptual proximity of genetic concepts through the ecological niche approach. For this purpose, we surveyed 995 9th graders. The areas covered in the survey were four genetic concepts: gene, chromosome, mitosis, and meiosis. The questionnaire presented biological concepts or terms related to each area, and the respondent marked the relevance between the presented biological concepts or terms and each area on a scale of 1~30 points. With 9th grade students, we analyzed the change of genetic concepts through class by the ecological niche approach. Through class, the total number of concepts increased in all of the areas, and the increase was smallest in the area of meiosis followed by mitosis, chromosome and gene. Relative density decreased with increases in the number of concepts. The conceptual diversity index also increased through class in all of the areas, and the increase was smallest in the area of meiosis followed by mitosis, chromosome and gene. In addition, difference in the relative density of concepts was reduced after class, and difference in the score of relevance was also reduced and consequently similarity among concepts increased. From these results were drawn conclusions as follows: First, through class, the conceptual diversity of genetic concepts increased. Second, through class, the conceptual proximity of genetic concepts increased.

In this study, we developed tasks including cognitive scaffolding for students to explain scientific phenomena using valid evidences in science classroom and sought to investigate how tasks influence the development of small group scientific argumentation. Heterogeneous small groups in gender and achievement were organized in one classroom and the tasks were applied to the class. Students were asked to write down their own ideas, share individual ideas, and then choose the most plausible opinion in a group. One group was chosen for investigating the effect of tasks on the development of small group argumentation through the analysis of discourse transcripts of the group in 10 lessons, students' semi-structured interview, field note, and students' pre- and post argument tests. The discrepant argument examples were included in the tasks for students to refute an argument presenting evidences. Moreover, comparing opinion within the group and persuading others were included in the tasks to prompt small group argumentation. As a result, students' post-argument test grades were increased than pre-test grades, and they argued involving evidences and reasoning. The high level of arguments has appeared with high ratio of advanced utterances and lengthening of reasoning chain as lessons went on. Students had elaborate claims involving valid evidences and reasoning by reflective and critical thinking while discussing about the tasks. In addition, tasks which could have various warrants based on the data led to students' spontaneous participation. Therefore, this study has significance in understanding the context of developing small group argumentation, providing information about teaching and learning context prompting students to construct arguments in science inquiry lessons in middle school.

The purpose of this study was to identify the differences in classification skills shown in classification activities between the gifted and regular students in elementary schools. The subjects for the research consisted of six gifted students in an institute for the gifted for science annexed to P school district in Gangwon-do and 6 students at B and M general elementary schools. Results were as follows: The time taken for classification activities of the gifted was shorter than regular regardless of subjects for classifying. The number of standards for classifying for the gifted was more than regular students. Coefficient for measuring classification skills of the gifted was higher than regulars regardless of age. Consequently, there was a difference in the time taken for classifying and generating the number of standards and in a numerical index of classification activities performed at science classes between the science gifted and the regular students.

Problem-based learning (PBL) is an effective teaching-learning strategy for enhancing students' motivation, problem solving ability, and creativity. Its educational values coincide with the aim of open-inquiry activity introduced in 2007 revised national curriculum. From this aspect we designed the PBL open-inquiry program and implemented to 202 first year middle school students in Gyeonggi provincial office of education for one semester. We developed an energy related PBL problem. The program was designed in four steps: 'understand the problem,' 'investigate information,' 'solve the problem,' and 'present and evaluate the result.' Through the program, students did such activities as 'make Know/need to know chart,' 'group discussion,' 'search information,' and 'preparation of group report.' After completing the program, a survey was conducted to understand the students' perception of the program. The results are as follows: First, 40.6% of students showed positive attitude toward the program. Especially, students responded that 'make Know/need to know chart' was very useful. However, some students responded that 'search information' and 'preparation of group report' were difficult to perform. Second, male students showed positive attitude toward the PBL program compared to female students. Also students had higher scores in attitude toward science, showed more positive attitude toward the PBL program. Third, there was a significant correlation between attitude toward science and perception of PBL steps. Based on survey results, some suggestions were made for teachers who were planning to implement PBL in open-inquiry program.

Journal of The Korean Association For Science Education, volume 31, issue 5, 2011, Pages 734~744
The purpose of this study was to identify middle school students' mental models on plate tectonics and to compare the mental models of verbal-learning-style students with those of visual-learning-style students. 94 student participants in 9th grade were requested to draw and explain three topics; generation of magma, the formation of the mountain range and the interior of the Earth. The criterions for analyzing the mental models are derived from the data of the drawing task. The research results were as follows: The mental models on the generation of magma were classified as 'unstable model,' 'partial casual model,' 'causal model,' and 'conceptual model.' On the other hand, the mental models on the interior of the Earth were classified as 'static unstable model,' 'dynamic unstable model,' and 'conceptual model.' Students holding 'unstable model' were unable to relate the plate collision and the magma generation. They showed a variety of alternative conceptions of study areas, such as 'magma is generated from the core' and 'the mountain is formed by rising of the plates themselves.' Also, visual-learning-style students showed higher proportion of conceptual models and lower proportion of unstable mental models than verbal-learning-style students on three topics. The findings revealed that the students tend to have different concepts on the plate tectonics depending on their learning style.

In this study, we investigated the interlanguage of ninth graders that was used to classify and explain the phenomena related to the change of the matters in a group discussion and semi-structured interview. The patterns of the interlanguage were classified and analyzed through the change of their understanding of science languages. The analyses of the results suggested that the interlanguage of the students are classified into the three patterns according to its meaning and form. Pattern 1 is science language used in combination with everyday language to express scientific meaning. This was used by most students regardless of the level of understanding of science languages. Pattern 2 is everyday language used to show scientific meaning, which was used by students who had better understanding of science languages than the others. Pattern 3 is using languages with multiple meaning, which was mainly used by students who have superficial understanding of science languages. Educational implications of these findings are discussed.

This study was designed to investigate the relations of motivation to related variables, and the motivation by student's variables basically through measure of motivation system about science learning. For this, 496 fourth-grade students and 425 eighth-grade students were required to accomplish a questionnaire on behavioral inhibition/activation system about science learning (SL-BIS/BAS), and self-efficacy. Based on these materials, SLBIS/BAS by student's variables and relations between the system to self-efficacy were analyzed. The result of this study shows the following:First, the sensitivity about SL-BIS in the eighth-grade was higher than in the fourth-grade. But sensitivity about SLBAS and self-efficacy in the eighth-grade was lower than in the fourth-grade Hence, the difference in sensitivity about SL-BIS/BAS agree with difference in motivation. Second, there were low negative correlation with SL-BIS and self-efficacy, and positive correlation with SL-BAS and self-efficacy. In addition, two systems account for 41% of self-efficacy, it showed that SL-BIS/BAS relates to self-efficacy. Through the results of this study, relations of motivation to related variables, and the motivation by student's variables were identified. These results would be helpful for teachers to understand the difference about motivation by students' variables and to make a plan for the appropriate strategies for learners.

Journal of The Korean Association For Science Education, volume 31, issue 5, 2011, Pages 770~787
The purpose of this study was to analyze science-gifted students' knowledge-generation processes by analyzing students' inquiry journal. As a result, first, science-gifted students showed various knowledge-generation processes, but they were limited to inductive thinking and abductive thinking, and their thinking processes were very simple. Second, most of the knowledge-generation processes of science gifted were simple, repetitive and diagrammatic processes because of observation and empirical situation of a limited scope. And a simple and repetitive diagram was generated by a simple variable selection and design, observation in limited scope, unbiased intervention by subjective thinking, and absence of exploration or finding errors. And they showed often a logical leap of reasoning.

Journal of The Korean Association For Science Education, volume 31, issue 5, 2011, Pages 788~800
The purpose of this study was to investigate the elementary school teachers' perception of science writing. In this study, 10 elementary school teachers who have taught in the 3rd or 4th grade science lesson in 2010 were selected. Researchers constructed interview guide in three parts including the teachers' understanding of science writing, the status of science writing teaching and the difficulties of science writing in their classes. For the investigation, semi-structured in-depth interviews with 10 elementary school teachers were conducted individually. The results showed that the elementary school teachers were unfamiliar with the word ‘science writing’ and considered science writing as a writing using science learning contents. Also, they think that teaching science writing in their science lessons was not needed and didn't assess and provide detailed feedback with the students' written works. Most teachers needed teaching materials and assessment tools for science writing. To develop elementary teachers' understanding of the value and use of writing for learning in science, they will need to participate in science writing programs for in-service teachers and various teaching materials and assessment tools should also be developed.

The purposes of this study were to understand what is physics teachers' perceptions of idealization and to explore their teaching experiences about idealization in their physics classes. In order to achieve these research purpose, we conducted in-depth interviews with ten Korean physics teachers. The interview data was transcribed and analyzed interpretively. The results are as follows: (1) Physics teachers are not familiar with the term of 'idealization' but they understand the meaning of idealization and ideal condition. (2) Physics teachers understand the necessity of explicit mentions of idealization and ideal conditions in physics classes. (3) Physic teachers adapt conceptions of idealization and ideal condition into their lectures, experimental classes and evaluation strategies. Thus, the results of this study can provide theocratical understanding of idealization. It will help develop teacher education programs and physics teaching strategies. This research also suggested follow-up research questions about idealization in the physics education field.

The purpose of this study was to analyze professionals' opinion about science education using history of science. For this purpose, we surveyed professionals in the field of science education and history of science (HOS), 30 professionals in the first survey and 84 professionals in the second survey. The results are as follows: First, they focused the nature of science in the science education using HOS. Second, they suggested the need for development of teaching and learning materials for using HOS in class. Third, they proposed action-based science teacher training for using HOS. Fourth, there appeared differences of professionals' opinion in some areas. Lastly, they did not make a high agreement in the need of history of eastern science including history of Korean science. It is necessary to develop teaching and learning materials in the history of eastern science.
