This study aims to explore a learning progression for eight core concepts of middle school science using constructed response items in the national assessment of educational achievement (NAEA). For this purpose, a total of 7,390 responses of the 9th graders on 8 constructed response items in NAEA conducted in 2015 were inputted by computer and the inputted answers were analyzed and classified into different levels. After completing this process, five levels were set for each construct and a construct map was created according to the levels. In this study, the construct map was written in a progression-based rubric format, which was used as a criterion for leveling the answers of all students. In addition, the Rasch model was applied to measure the scores and achievements of the respondents by means of statistical analysis to correlate the scores of the students with the achievement levels of the constructs. Lastly, a preliminary learning progression was created by revising the construct map reflecting the results of Rasch model application. This study was meaningful in that it explored the possibility of developing the learning process by using constructed response items in NAEA. However, the preliminary learning progression developed in this study is still hypothetical and inferential because it is not longitudinally traced to individual students. Therefore, it is necessary to continually revise and supplement through iterative research process.

The purpose of this study is to analyze what kinds of science education theories are targeted in the "Examination for Appointing Secondary School Science Teachers (EASST)." For the analyses, we extracted the contents related to the science education theories in the question items of the EASST of 2008 through 2012, and categorized those theories into science curriculum, history of science and philosophy of science, scientific inquiry, theory of teaching and learning, model of teaching and learning, and assessment. The results of this study indicated that the theory of teaching and learning appeared most frequently and there were high proportions of question items related to the following topics: contents in science curriculum, scientific method, contemporary philosophy of science, process of inquiry, Ausubel's theory, learning cycle model by Lawson, cooperative learning, criteria of performance assessment, and etc. While we, as science educators, believed that the other categories such as 'history of science' provides important topics for pre-service science teachers, questions items dealing with those were rarely found in the past EASSTs. As EASST has strong influences on the professional developments of pre-service science teachers, more research should be pursued on how much and what domains of science education theories would be appropriate for the test.

The purpose of this study is to look into Various educational supports for the gifted students in science to decide proper career planning through Research of Career Consciousness of the Gifted Students in Science. The subject of this study is new students entered into KAIST from the year of 1996 to 2003. They are approximately 500 students yearly and 3,613 totally and more than 90% of students have answered. The Questions are largely 3 items. One is 5 Q's of entering universities, second is 2 Q's of life plans in the university and the last is 2 Q's of career plans after graduation. As a result, the gifted students in science tend to find out and develop their interest and aptitude early and decide their future much earlier than other students. Nevertheless the gifted students in science worry about their future a lot as well. However they ask their problems to friends, seniors, and parents rather than teachers, professional consultants in general it could say no sufficient systematic guidance and consulting available for them. So it does require that some subjects such as guidance for career planning should be included in university curriculum and furthermore not only schooling but also the systematic structure of persistent consulting about gifted student's general life should be planned as well.

The purposes of this study were: (1) to revalidate the revised Systems Thinking Measuring Instrument (Re_STMI) reported by Lee et al. (2024) among Vietnamese high school students and (2) to investigate the differences in systems thinking abilities between Korean and Vietnamese high school students. To achieve this, data from 234 Vietnamese high school students who responded to translated Re_STMI consisting of 20 items and an Scale consisting of 20 items were used. Validity analysis was conducted through item response analysis (Item Reliability, Item Map, Infit and Outfit MNSQ, DIF between male and female) and exploratory factor analysis (principal axis factor analysis using Promax). Furthermore, structural equation modeling was employed with data from 475 Korean high school students to verify the latent mean analysis. The results were as follows: First, in the item response analysis of the 20 translated Re_STMI items in Vietnamese, the Item Reliability was .97, and the Infit MNSQ ranged from .67 to 1.38. The results from the Item Map and DIF analysis align with previous findings. In the exploratory factor analysis, all items were loaded onto intended sub-factors, with sub-factor reliabilities ranging from .662 to .833 and total reliability at .876. Confirmatory factor analysis for latent mean analysis between Korean and Vietnamese students yielded acceptable model fit indices (χ²/df: 2.830, CFI: .931, TLI: .918, SRMR: .043, RMSEA: .051). Lastly, the latent mean analysis between Korean and Vietnamese students revealed a small effect size in systems analysis, mental models, team learning, and shared vision factors, whereas a medium effect size was observed in personal mastery factors, with Vietnamese high school students showing significantly higher results in systems thinking. This study confirmed the reliability and validity of the Re_STMI items. Furthermore, international comparative studies on systems thinking using Re_STMI translated into Vietnamese, English, and other languages are warranted in the context of students' systems thinking analysis.

The research paid attention to the fact that top 10% high achievers of girls in high schools are not equally provided with opportunities for science gifted education in Korea. For this reason, the research examined gender differences in science achievement and science affective domain through employing PISA 2006 science achievement test and survey of science affective domains. The research subjects of 132 students as top 10% high achievers extracted from those 1,409 students who were nationwidely sampled and responded to the science achievement test and science affective domain survey in July 2008. The responses by 132 students of top 10% high achievers were analyzed. The findings revealed that there is no significant difference of science achievement and most items of science affective domain survey between girls and boys of top 10% population in high schools. Further, it was indicated that top 10% high achieving girls have interest, self-concept, self-efficacy, future job aspiration in science as high as boys. In conclusions, further attentions to provide more opportunities of science gifted education for girls are called for.
