The purpose of this study is to analyze the student`s modeling patterns of modeling experiments. The 1st year students who were taking the general chemistry laboratory course performed three modeling inquiry experiments and submitted laboratory reports. Students expressed the model in a formula form and/or a written form. Student`s modeling patterns could be classified by five types; `Refining tentative modeling`, `Accepting alternative modeling`, `Discarding tentative modeling`, `Failing to find causes`, `Disbelieving results`. This modeling experiment provides for students the opportunity for understanding how a scientific model is created and what the nature of scientific modeling is.

The purpose of this study was to investigate the educational factors on career choice of science-gifted students to science and technology bound universities and the difference of perception in regards to group factors. In addition, this study aimed to examine the effects of science-gifted education and critical events in relation to career choice to science and technology bound universities. For the study, 104 university freshmen, 75 males and 29 females, were sampled from UNIST (Ulsan National Institute of Science and Technology), that many science high school graduates entered this year. The survey was conducted with questionnaires to do with the perceptions concerning career choice and educational factors that cause them to choose such career directions. The educational factors on career choice to science and technology bound universities were classified as 3 main categories such as educational environment factor (teaching-learning factor), human factor, attitude towards science factor and the subcategories within each category. The research findings are as follows: First, the factors were closely connected with each other and `the project centered classes` were highly interrelated with other educational environment factors such as `the experiment activity and environment for the activity` and `influence of teachers (professors).` Second, the female students and graduates of the science high school were more positively influenced by the educational environment and human factors on their decision for career than male students and graduates of the general high school. Third, this research found that historical scientific knowledge, perception of scientists` social status and job applications in the science field gave less influence rather than other factors on their decision for career. As a result of examining critical events for science-gifted education in relation to career choice to science and technology bound universities, numerous students mentioned that the extracurricular science activities such as science camps and field trips gave significant effects on students` career choices to science and engineering fields.

Educational communities around the world have concentrated on integrative efforts among science, technology, engineering and mathematics (Science, Technology, Engineering, and Mathematics: STEM) subjects. Korea has focused on integrative education among STEAM (Science, Technology, Engineering, Arts, and Mathematics) school subjects to raise talented human resources in the fields of science and technology. The purpose of this study was to analyze secondary school science, technology, and mathematics teacher`s perceptions and needs toward integrated education and integrative STEM education. A total of 251 secondary school teachers from all areas of the country who have taught science, mathematics, and technology were surveyed by using a self-reported instrument. The findings were as follows: First, teachers have used little integrated education in their classes due to insufficient time in the actual preparation of the integrated education and the lack of expertise, teaching experience, and teaching-learning materials for the integrated education, while they have positive thoughts about the need of integrated education. Second, they presented several needs to facilitate the integrated education: development of a variety of integrated programs, school administrative and financial support, and in-service teachers` training. Third, overall perception toward integrated STEM education was not sufficient, but most teachers perceived the need toward integrated STEM education due to students` development in their creativity, thinking skills, and adaptability. Fourth, they perceived that it was imperative to develop the various integrated STEM education programs, distribute the materials, and help STEM teachers` understanding toward integrated STEM education. Fifth, they perceived that the most relevant method to integrate STEM subjects was the problem solving approach. In addition, they appreciate that the integrated STEM education is highly efficient in not only developing integrated problem solving skills and STEM related literacy, but also in positively impacting the rise of talented human resources in the fields of science and technology. In order to increase the awareness of STEM-related secondary school teachers and vitalize the integrated STEM education, it is necessary to develop and spread a variety of programs, effective teaching and learning materials, and teachers` training programs.

Journal of The Korean Association For Science Education, volume 32, issue 1, 2012, Pages 46~63
DOI : 10.14697/jkase.2012.32.1.046
The purpose of this research is to explore factors which influence visitors` attention on exhibition panels by analyzing visitors` attention according to topic types and visitor group types. The subjects of this research are exhibition panels of a Tesla Coil exhibition in the Gwacheon National Science Museum. The exhibition panels` topic are basic concepts, explanations of phenomena, operating principles, applications and historical background. These topics are selected through a survey of visitors` intellectual needs for a Tesla Coil. Five new exhibition panels according to the topics are developed and visitor groups` behaviors in front of the panels are recoded in natural situations. The total participant groups are 586 groups, which includes individual student (30.0%), individual adult (20.6%), student group (28.2%), adult group(2.4%), and family group (18.8%). Visitors` attention to exhibition panels is sub-categorized into attracting power and holding power. Attracting power is defined by the percentile of group numbers who attend to an exhibition panel more than 3 seconds to the total group numbers who attend to an exhibition panel for more than a glance. Holding power is defined by average attention time and decay time. The attracting powers of historical background and application panels are 72.3% and 68.8% respectively, while that of the basic concept panel is 47%. Average attention times of explanation of phenomena and operating principle are 37.0 and 34.2 seconds, while those of historical background and application panels are 25.4 seconds. The decay times of each panel shows the same patterns of average attention times. Attracting powers of panels easy to approach and holding powers of panels with in-depth scientific concepts seems to be high. Attracting powers of the individual adult, family, and student group are 66.9%, 66.4% and 62.4% respectively, while the attracting power of the adult group and individual student are 57.1%, and 55.7%. Average attention times of the student group, family, adult groups are 34.0, 33.0, 31.6 seconds respectively, while that of individual student is 19.5 seconds. The decay times of each group shows the same patterns of average attention times. Both of attracting powers and average attention times of the student group and family group are high, while both of individual student are low. Tentatively, attracting powers of exhibition panels seems to be influenced more by topic types of panels, and holding power seems to be influenced more by group type. But these results are very limited and further studies are needed.

DOI : 10.14697/jkase.2012.32.1.064
The purpose of this study was to analyse middle school students` images and perceptions about scientist, technician and engineer and to compare the images of male students with those of female students. Fralick et al.(2009)`s "Draw a scientist at work and draw an engineer at work" was modified and administered to 110 middle school 3rd grade students (43 male students, 67 female students) from 5 middle schools. They drew the figures at work and took explanation of what the person was doing in a drawing. The results of this study were as follows; First, the representative image of scientist was the man with glasses and lab gown performing the chemical experiment. There were no significant differences between the male students and female students in terms of the scientist images. Second, the representative image of technician was the man who was fixing a car and working with his hands. The technicians were illustrated as working with tools such as wrench, hammer and so on. There were no significant differences between the male students and female students in terms of the technician images. Third, the students involved in this study frequently perceived male engineers as working indoors. But perceptions about performance of engineers were significantly different between male students and female students. A majority of male students recognized that engineers should design, invent and create the products, however many female students perceived the engineers as car mechanics. Fourth, the students perceived differently the scientists` task compared with the technicians`, but they had difficulty in distinguishing the scientists` task from the engineers` task.

Journal of The Korean Association For Science Education, volume 32, issue 1, 2012, Pages 82~94
DOI : 10.14697/jkase.2012.32.1.082
In this study, epistemological views of middle school students on scientific inquiry were investigated. The Views of Scientific Inquiry Questionnaire was administered to 141 9th graders. The questionnaire consists of five open-ended items concerning the contexts of scientific investigation, the methods of scientific investigation, the interpretation of data, and the data and evidence. Analyses of the results indicated that their epistemological understanding of scientific inquiry were not adequate on the whole. Although the students suggested a variety of factors influencing scientists` decisions on the questions and the methods of investigation, many of the factors were minor. Only a few students specifically described the activities of scientists and the constituents of "scientific" activity, and students did not demonstrate adequate understanding of experimentation in science and multiple scientific methods. Moreover, the percentage of students who possessed the informed view that data can be variously interpreted was found to be low. The students also did not understand the distinctions between data and evidence. Educational implications are discussed.

The research evaluated the effects of the improvements in scientific inquiry for elementary school students and focused on the development and application of the explicit and reflective learning strategy through observation and classification. The explicit and reflective learning strategy was modified and completed with the review of the experts after the development of the draft based on the theoretical approach. The students were evaluated for their academic achievements in scientific inquiry skills before and after taking the course. The results were as follows: First, the steps of the developed learning strategy (1) to motivate, (2) to explore reflectively, (3) to guide explicitly, (4) to inquire explicitly, and (5) to verify reflectively were set to reflect the verification. Second, the results of applying the developed model to the lessons based on the quantitative analysis was effective for observation and classification skills in the quest for improved performance of the whole (the sum of observation and classification, inquiry skills) and the observed features, but there was no effect on classification. Also, the lessons applied the developed teaching strategy and showed effectiveness in improving academic achievement. Particularly in analyzing the relationship between the academic achievement and exploration capabilities, in order to improve academic achievement, the importance of improving inquiry skills was found. Third, the qualitative analysis of teaching and learning strategy developed by applying the lessons of this teacher guide and small group activities through the explicit and reflective observation and classification of the student learning activities showed the significant improvement of ability of the scientific inquiry skills. In addition to the improvement in the abilities of the classification showed after the formation of the most basic observation skills of the scientific inquiry.

This study explored to what extent Korean science teachers perceived socioscientific issues (SSI) as an effective instructional tool for creativity and character (CreActer) education; which was recently announced as a main goal for the Korean National Science Curriculum 2009. The guiding research questions were as follows. (1)How do science teachers conceptualize the relationship between creativity and character in the context of science classes? (2) What do science teachers think about the possibility of CreActer education through SSI in science classrooms? Thirty science teachers participated in individual interviews (each lasted 20-90 minutes). In the results, the teachers` perceptions on CreActer education and SSI for CreActer education were categorized into four profiles. Eleven teachers in Profile A thought that creativity was positively correlated with character education because their understanding of creativity and character embraced a very broad range of elements. They mentioned that addressing SSI in the science classes would be satisfactory to cover those elements of CreActer education. Six teachers in Profile B mentioned similar elements of creativity and character of Profile A, but reported that, in their experience, creativity was often inversely correlated with character. However, they responded that addressing SSI would be a good way to integrate creativity and character in the science classes. Ten teachers in Profile C believed there was no relationship between creativity and character, but took a positive stance on CreActer education through SSI. Unlike Profile A and Profile B, they tended to regard character as only an interpersonal virtue. And three teachers in Profile D had a narrow perspective on CreActer education. Not only did they think creativity had no relationship with character, but also disagreed that CreActer education would be activated by addressing SSI in science classrooms. The results imply that SSI could be used as an effective instructional tool for CreActer education, but this can be possible when science teachers expand their view on CreActer education.

This study investigated factors of creativity and interaction between factors that are revealed when gifted students designed scientific experiments. For this, we firstly developed items which required the written process of designing experiments to explore creativity factors. Then, we used these items as a part for letters of self-introduction to students who applied for 2011 correspondence education of general physics for the Korea Physics Olympiad. 513th letters of self-introduction which were analyzed to investigate factors of creativity in view of creativity definition after researchers` consultation, which specifically means a combination of divergent and convergent thinking. The results were as follows; (1) in the step of hypothesis building, we could not only find Originality and the Flexibility & Fluency, which were factors of divergent thinking, but also Coherency and Elaborateness, which were factors of convergent thinking. (2) in the step of the hypothesis testing, we could explore Originality, Flexibility & Fluency in divergent thinking and Coherency, Reliability, Clarity, Elaborateness in convergent thinking. (3) we also figured out three creativity types of gifted students from the viewpoint that creativity is a consequence of interaction between divergent thinking and convergent thinking; a) Type A showed divergent and convergent factors of creativity in the step of hypothesis building. However, type A did not include divergent factors of creativity on the process of the hypothesis testing. b) Type B had divergent and convergent factors of creativity on the process of the hypothesis testing, but it had not convergent factors of creativity on the step of hypothesis building. c) Finally, in Type C, only divergent factors of creativity appeared on the process of the hypothesis testing, but convergent factors of creativity could be found on the step of hypothesis building and hypothesis testing.

The purpose of this study was to examine the relation between students` reflective thinking and providing the reading framework in implementation of argument-based inquiry using the Science Writing Heuristic (SWH) approach. Participants of this study were 60
grade students (two classes). One class (31 students) was assigned to an experimental group and the other class (29 students) was assigned to a comparative group. For the experimental group, five activities using the reading framework with SWH writing template were implemented, while three activities using the reading framework with the SWH writing template and two SWH activities without the reading framework were implemented for the comparative group. The result of this study showed that there was no significant difference in students` reflective thinking between both groups. However, results indicated that providing the reading framework with SWH approach facilitated students` reflective thinking. Therefore, the findings show that providing the reading framework consistently in the SWH approach was effective when it came to facilitating students` reflective thinking.

DOI : 10.14697/jkase.2012.32.1.160
The purpose of this study is to understand raters` errors in rating performance assessments of science inquiry. For this, 60 middle school students performed scientific inquiry about sound propagation and 4 trained raters rated their activity sheets. Variance components estimation for the result of the generalizability analysis for the person, task, rater design, the variance components for rater, rater by person and rater by task are about 25%. Among 4 raters, 2 raters` severity is higher than the other two raters and their severities were stabilized. Four raters` rating agreed with each other in 51 cases among the 240 cases. Through the raters` conferences, the rater error types for 189 disagreed cases were identified as one of three types; different salience, severity, and overlooking. The error type 1, different salience, showed 38% of the disagreed cases. Salient task and salient assessment components are different among the raters. The error type 2, severity, showed 25% and the error type 3, overlooking showed 31%. The error type 2 seemed to have happened when the students responses were on the borders of two levels. Error type 3 seemed to have happened when raters overlooked some important part of students` responses because she or he immersed her or himself in one`s own salience. To reduce the above rater errors, raters` conference in salience of task and assesment components are needed before performing the holistic scoring of complex tasks. Also raters need to recognize her/his severity and efforts to keep one`s own severity. Multiple raters are needed to prevent the errors from being overlooked. The further studies in raters` tendencies and sources of different interpretations on the rubric are suggested.

There is growing recognition that secondary students must be given the opportunity to write in their science classrooms as well as in scientific inquiry based learning situations, yet the development of writing education standards for secondary school science teachers still needs to be addressed. The primary objective of this research was to explore the writing education standard for secondary school science teachers. The research objective was attained through the use of literature analyses. Drawing upon those results of the related literature analyses, this study suggests a list of writing education standards for secondary school science teachers. The list consists of 17 education standards and includes 42 sub-standards in total across four education areas.
