Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 201~209
DOI : 10.14697/jkase.2012.32.2.201
This study aims to explore patterns and characteristics of coordination between evidence and theories which were found in pre-service elementary teachers' writing for their science inquiry. Five science inquiry activities and a total of 115 writings of the participant teacher at the elementary teacher preparation university in Korea were collected and analyzed for this study. Based on the writing analyses there were found four types of coordination between the evidence and theory. We proposed four types as: Type 1-Consistency of evidence and theory; Type 2-Consistence of evidence and theory including more extension or elaboration of theory; Type 3-Inconsistence of evidence and theory Type 4-Inconsistence of evidence and theory followed by coordination of them. Firstly the findings indicated that the most to least frequent types were Type 1, Type 3, Type 2, and Type 4. The most frequent type was Type 1. It is interpreted that theory in the inquiry questions were frequently figured out by participants and they selected supporting evidence out of data found. There were rarely found relations between activity topics and frequencies of coordination types except in activity 1. The findings in this study will connect to the point of how students collaborate their previously owned knowledge with experiment planning, data analysis and interpretation and making of their own scientific claims.

Park, In-Suk ; Kang, Soon-Hee ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 210~235
DOI : 10.14697/jkase.2012.32.2.210
The purpose of this study was to develop a valid and reliable assessment tool for measuring scientific creative problem solving ability for middle school students. To achieve this aim, an assessment framework, four assessment items, and detailed rubrics for scientific creative problem solving were developed. The assessment framework had three dimensions (i.e. science contents, inquiry process, and thinking skills) and sub-elements for each dimension. The assessment items were tested with 320 middle school students in order to determine reliability, difficulty, and item discrimination. Science teachers and experts in science education checked the validity of the items and the rubrics. The results proved that the assessment tool was reliable enough to evaluate students' scientific creative problem solving skills.
Sub-Component Extraction of Inquiry Skills for Direct Teaching of Inquiry Skills
Lee, Eun-Ju ; Kang, Soon-Hee ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 236~264
DOI : 10.14697/jkase.2012.32.2.236
The purpose of this study is to provide teachers with sub-components of inquiry skills and help them to give direct instructions on the skills to their students. Inquiry skills and strategies are considered by-products of science and inquiry instruction by most of the science teachers. On the other hand, much research shows that many students are not familiar with the way that they can use inquiry skills therefore direct instruction on the inquiry skills is needed. The lack of guidance on the sub-components for the inquiry skills, however, results in science teachers' ignorance of the inquiry skills. As shown in the previous studies which suggest that without teachers' guidance, students cannot acquire the intended skills, and it is necessary to inform science teachers of the necessity for direct instruction on the inquiry skills and strategy as well as give them the sub-components of the inquiry skills. On the basis of the results from the previous research on the inquiry skills, this study presents the sub-components of basic inquiry skills (observation, classification, measure, prediction, and reasoning) and integrated inquiry skills (problem recognition, hypothesis formulation, control of variables, data transformation, data interpretation, drawing conclusion, and generalization).

Kwon, Nan-Joo ; Ahn, Jae-Hong ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 265~278
DOI : 10.14697/jkase.2012.32.2.265
The purpose of this study is to investigate research trends about convergence and integrated science education through the analysis of theses published from January, 2000 to June, 2011 in the scientific journals. For the analysis of the theses, we set standards of analysis including the number of theses, integrated types, research methods, the designs of study and the objects of study. The number of theses used for the analysis were 110 volumes and these were limited to the Journal of KASE (The Korean Association for Science Education) and Journal of KESES (The Korean Society of Elementary Science Education). The results of the study are as follows. First, in the analysis of theses according to the published year, we discovered that the volumes of theses related to convergence and integrated science education were only about 10% of theses published in the journals. Second, the theses about STS education and integration type were the most common type in the integrated types, and the next things were integration type with other scientific fields, and integration type with other subjects. Third, 50% of theses have focused on the 'analysis of effect' as research methods and 45.5% of the theses have used 'quantitative research' as the designs of study. Fourth, the most common study in the theses was to target elementary school students, then it was middle school students, then high school students, literature, teachers, would-be teachers, and the general public. On the basis of the results of this research, we suggest that various studies can develop student's creativity and teacher's recognition through STEAM education and must be presented for the successful STEAM education.

Yoon, Heo-Jeong ; Yoon, Won-Jeong ; Woo, Ae-Ja ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 279~292
DOI : 10.14697/jkase.2012.32.2.279
Prospective high school students and science teachers' perceptions of 'advanced material', which was first introduced in the science textbooks of the 2009 revised curriculum, were surveyed. One thousand four hundred and ninety nine students and 123 teachers from Seoul, Incheon, and the Kyeonggi areas participated in this survey. The results are as follows. First, the attitude of students and teachers towards 'advanced material' was positive, but their interests in 'advanced material' was low. Also, some teachers mentioned that 'advanced material' was one of the difficult subjects to teach. Second, the perception of 'advanced material' was relatively low for both students and teachers. Both of them had heard of 'advanced material' through various routes, however not many of them thought that they knew what 'advanced material' was exactly. Also there were some teachers who didn't understand the detailed information of 'advanced material'. Third, both students and teachers agreed that 'advanced material' was worthwhile to learn and teach. However, each party had their own desire of 'what to learn', 'what to teach', 'how to learn' and 'how to teach'. Based on the results, some suggestions were made for effective teaching of this new subject.

Lee, Eun-Mi ; Kim, Beom-Ki ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 293~305
DOI : 10.14697/jkase.2012.32.2.293
The purpose of this study was to analyze the secondary school students' reasoning types in regards to measurement and to get implications for science education. The subjects were 197 middle school students and 200 high school students. The PMQ1 written instrument was used to explore students' ideas. Students' ideas about measurement were classified in two types of point and set reasoning. The reasoning types distribution were analyzed by grade and measurement step such as data collection, data processing, and data comparison. Reasoning types distribution by measurement step indicated that set reasoning type showed high figures in data processing, but point reasoning type appeared in data collection, and data comparison. Set reasoning type increased significantly by grade in data comparison. The majority of students recognized that the true value of the measurand can not be determined.

Woo, Ju ; Rhee, Hyang-Yon ; Choi, Kyung-Hee ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 306~319
DOI : 10.14697/jkase.2012.32.2.306
The purpose of this study was to investigate high school students' learning style, perception of types of laboratory instruction, and the relationship between the learning style and preferred type of laboratory instruction. The participants of this study were 19 female high school students, from Incheon in Korea, who showed outstanding science grades. Dunn et al's revised Learning Styles Inventory (1997) was used for testing students' learning style. The students were asked to choose preferred and not preferred types of experiments and describe the reason of the choices after implementation of 4 types of experiments: verification, discovery, explorator, and investigation laboratory instructions. The findings of this study were as follows: Firstly, the students had a certain common learning style irrelevant to their personal characteristics, i. e; they showed high (self, teacher, parents) motivation and structure stimuli that was common in Korean students. Second, outstanding students prefer unstructured and open laboratory instructions. And those students were highly influenced by sociological and emotional stimuli. Third, students' learning style was related to their preferred type of laboratory instruction. Students preferring unstructured and open laboratory were influenced by sociological and emotional stimuli, while those preferring structured and closed laboratory were influenced by physiological stimuli.

DOI : 10.14697/jkase.2012.32.2.320
Understanding the relation between basic science and applied science is important for students in understanding the importance of learning science, the relationship between scientific knowledge and human life, and for enhancing their science motivation. In this study, we evaluated the statistical validity of this hypothetical model and explored the effect of gender and students' preferred courses (e.g., humanities, science, and art) on four dependent variables. We also evaluated the differences of students' understanding across scientific domains and students' understanding concerning basic and applied scientific knowledge. Three hundred and twenty five 10th grade students participated in this survey research. Statistically, we employed bivariate correlation, partial correlation, path analysis, two-way ANOVA, and repeated measures ANOVA. Our findings illustrated that our hypothetical model was statistically valid. In addition, the significant interaction effects of gender and students' preferred courses on each dependent variable were shown. Students have different levels of understanding of the convergence of basic and applied science, the relation between scientific knowledge and human life, and the importance of learning science across scientific domains (e.g., physics, chemistry, earth science and biology).
A Case Study on the Use of Mentoring as a Method of Improving Novice Teachers' Teaching Professionalism in Secondary Science-Gifted Education
Noh, Tae-Hee ; Kang, Seok-Joo ; Kang, Hun-Sik ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 331~345

As a case study on the use of mentoring as a method of improving novice teachers' teaching professionalism in secondary science-gifted education, this study investigated the characteristics of mentoring science instructions for science-gifted students at the plan, performance, evaluation, and post-mentoring stages of the classes. One mentor and two mentees were selected, and mentoring in each mentee's instructions was conducted during nine classes over three times. We observed the total classes, and analyzed taped videos, the materials, the transcripts for mentoring and in-depth interviews, and field notes. The analyses of the results indicated that the characteristics of mentoring instructions, at the planning stage of the classes, exhibited the construction of more systematic classes, the escape from the schema that science instructions for science-gifted students were instructions using somewhat difficult experiments and the uses of diverse teaching strategies, the influence of the psychological burdens on developing science-gifted education programs, and the increase of the time preparing the classes. At the performance stage of the classes, the characteristics included the improvement in the quality of the classes, the influence of the psychological burdens on teaching the classes, and the inducements of some confusion on performing them. At the evaluation stage of the classes, the characteristics included the provision of the opportunities in deeply reflecting my own classes, and the provision of the practical power for improving the classes. Finally, the characteristics at the postmentoring stage could be attributed to the increase of mentees' self-confidence about their instructions and some development of mentors' teaching professionalism/mentoring skills.

Shin, Dong-Hee ; Shin, Ha-Yoon ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 346~371
DOI : 10.14697/jkase.2012.32.2.346
The purpose of this study is to investigate the possibilities of science ethics education with history of science (HOS) and to develop its teaching and learning model for secondary school students. A total of 72 cases about science ethics were extracted from 20 or more HOS books, journal articles, and newspaper articles. These cases were categorized into 8 areas, such as forgery, fabrication, violation of bioethics in testing, plagiarism and stealth, unfair allocation of credit, over slander, conjunction with ideologies, and social responsibility problems. The results of this study are as follows. First, research forgery, occurring in the process of the research, was the most frequent in HOS. Second, we developed eight teaching lesson plans for each area. Third, we proposed a teaching and learning model based on the developed lesson plans as well as related teaching and learning models in the fields of science ethics education, ethics education, and history education. Our model has five steps, 'investigating-suggesting casesclarifying problems-finding alternatives-summarizing'.

This study aims to identify unique small group norms and their influence on the process of constructing a scientific model. We developed instructional materials for the construction of a model of blood flow in the heart and conducted research on eighth-grade students from one middle school. We randomly selected 10 small groups, and videotaped and recorded their dialogues and behaviors. The data was categorized according to the types of interaction and then analyzed to investigate the characteristics of group norms and models in one or two representative groups for each type. The results show that the types of interaction, the quality of the group models, and the group norms were different in each group. Even though one teacher guided students through the same task in the inquiry context, each group revealed different patterns of discourse and behavior, which were based on norms of cognitive responsibility, the need for justification, participation, and membership. With the exception of one group, there was little cognitive responsibility and justification for students' opinions. Ultimately, these norms influenced the model construction of small groups. A group that forms norms to encourage the active participation and justify members' opinions with cognitive responsibility was encouraged to do inferential thinking and construct a group model close to the target model. This study has instructional implications for the establishment of a classroom environment that facilitates learning through small group activities.
Development of a Theoretical Model for STEAM Education
Kim, Sung-Won ; Chung, Young-Lan ; Woo, Ae-Ja ; Lee, Hyun-Ju ;
Journal of The Korean Association For Science Education, volume 32, issue 2, 2012, Pages 388~401
DOI : 10.14697/jkase.2012.32.2.388
This study attempted to propose a theoretical model for STEAM education, entitled to the Ewha-STEAM education model, which could provide more concrete guidelines for science educators and curriculum developers to execute STEAM ideas. We identified key knowledge and key competencies to nurture future creative/convergent human resources. Key knowledge included an understanding of core ideas cutting across traditional disciplinary boundaries as well as the nature of different disciplines. And additionally, key competencies implied such abilities as to explore the scientific world, to resolve problems, and to communicate and collaborate with others. We also added creativity and character as an essential part of key competencies. In order to provide more specific guidelines when developing, implementing, and evaluating STEAM curriculum, we suggested three elements of convergence to consider: 1) unit of convergence (i.e. concept/skills, problem/phenomenon, activity), 2) degree of convergence (i.e. multi-disciplinary, inter-disciplinary, extra-disciplinary), and 3) context of convergence (i.e. personal, societal, global). It is expected that the Ewha-STEAM education model would contribute towards diverse education communities understanding the direction of STEAM education and its educational potentials.

This study investigated the effects of the instructions using analogies in learning the concept of saturated solution by the analogy presentation types and the verbal learning styles upon the mapping understanding, the mapping errors, and the perceptions of the instruction. Fifth graders (N=123) at an elementary school were selected and assigned to VA (n=63) and VPA (n=60) groups. As a pretest, a test on the verbal learning style was administered. The students in the VA group learned the target concept with a verbal analogy, while those in the VPA group learned it with a verbal/pictorial analogy. After the students learned it, a mapping understanding test was administered. The students in the VPA group also administered the test on the perceptions of the instruction and some of them were interviewed in depth. The results revealed that the scores of the students with strong verbal learning preference in the VPA group were significantly lower than those in the VA group in the mapping understanding test. However, the scores of the students with weak verbal learning preference were not significantly different between the two groups. Five types of mapping errors were identified: failure to map, mismapping, rash mapping, impossible mapping, and mapping of a surficial feature. According to students' verbal learning styles, there were some differences in the frequencies of mapping errors in the two groups. Many students in the VPA group, regardless of their verbal learning styles, had positive perceptions of the instruction in various cognitive and motivational aspects. However, some of them also pointed out a few difficulties of the instruction. Educational implications of these findings are discussed.
