He purpose of this study is to design and apply a pilot assessment tools for scientifically gifted and talented elementary school students with lower grades. The assessment tool consists of three parts: homeroom teachers' recommendation, paper and pencil test and performance tests. The tools are verified whether they are suitable for unique characteristics of young children and enable to attract active participation. For suitability check, students' performance tests were inductively analyzed and 30 behavioral patterns were shown which were included and partially exceeded the level of lower elementary students' performance expectation in NGSS. As a result, we concluded that assessment tool developed in this study will be effective in discriminating young pupils' scientific talents. Then for participation check, we compared the number of coding references as an indicator of participation. Two cases were found that students with high interest participated passively in performance tests. We found these 'passive participants' had excessive scientific experiences and extremely narrow region of interest, during the process of complex interpretation between the results of this assessment tool and in-depth interviews with homeroom teachers. We found out in this study that newly developed tools can be used in school scene after modifying and elaboration through accumulation of more case studies.

Korean 7th national curriculum gave the right to elect the advanced subject such as physics II, chemistry II. Students could elect the subject by their aptitude and interest. But, actually, the choice was constrained by school circumstances such as the number of teacher and the number of class. high school students. We investigated the demand about school science and perception about scientifically specialized high school in which the students could have all advanced science subjects by the survey of 336 middle school students including 148 students in the science education center for the gifted, 220 high school students, and 70 science teachers in capital region. As results of this study, most of the high school opened chemistry and biology advanced subjects, but only 37.1% of them opend physics advanced subject. This constrained students' right of elect the subject by their interest. While most of middle school and high school students normally demanded the more experiment in the class and the easier science content, the students in the science education center for the gifted demanded more science class time. The students who wanted to have science career had very positive recognition of scientifically specialized high school and science teachers agreed to running the scientifically specialized high school.

The purpose of this study was to examine the validity of Multiple Intelligence Scales for Young Korean Children (MIS-YKC). Participants of this study were 357 children's parents and teachers from Seoul, Gyeongdo, Jeonlado & Choongchungdo. Data were analyzed by confirmatory factor analysis, Pearson's r and Cronbach's ${\alpha}$. Results are as follows. (1) Confirmatory factor analysis of MIS-YKC for parents MIS-YKC revealed that fit indices such as $X^2$=365.712 (df=168, p=.000), RMSEA=.057, SRMR=.047, NNFI=.935, CFI=.948. and MIS-KYC by teacher's evaluation $X^2$=436.765 (df=168, p=.000), RMSEA=.066, SRMR=.051, NNFI=.917, CFI=.934. (2) Correlations between multiple intelligence scales and IQ were significant. (3) Cronbach's ${\alpha}$ ranged from .80 and .86 for seven intelligence scales and .95 for the total scale by parents' evaluation. Cronbach's ${\alpha}$ is ranged from .76 and .91 for seven intelligence scales and .95 for the total scale by teacher's evaluation. All these results show that the multiple intelligence scales for young Korean children parents and teachers are quite reliable and valid.

The purpose of this study was to explore the factors that are critical for successful scientific inquiry activity in the classroom and to analyze the students' abilities of 'Doing' scientific inquiry. Two hundred and forty gifted science students in grades $7^{th}$ and $8^{th}$ participated in this study and demonstrated their abilities of framing questions and designing investigation through a survey questionnaire. The survey was developed for measuring factors in terms of personal and interactive variables that are needed for 'Doing' a successful scientific. Additionally, two other questionnaires were developed to measure students' abilities of framing testable questions and designing the investigation in a sequence. The results were as follows: Students' learning motivation factors as personal variable (self-confidence about group and inquiry activity, views about inquiry value) also considered as influential for students' group inquiry activity. Other four components of interactive variable (grouping, kinds of task, physical context, and teachers' role) were found to be influential in successful students' 'Doing' group inquiry activity. In students' evaluation of group inquiry activity, the grouping factor was the most critical one for a successful 'Doing' inquiry activity. Participating students showed some level of inability of in the process of framing inquiry question and designing investigation.

The purpose of this study is to figure out gifted elementary science students' improvement in performing open inquiry after peer review. In this study, gifted fifth-grade students performed open inquiry and review of each other as peers after the inquiry. Students' inquiries were evaluated and the influences of the feedback from the peer reviews were analyzed in relation to the inquiry performances. As a result of this study, three key points were discovered: First, the evaluation score increased with frequent feedback or long discussions. On the other hand, with less feedback, the evaluation score didn't rise. Second, there were three types of improvement in inquiry related to peer review: No. 1 was improvement after feedback given by themselves. No. 2 was reflection of feedback given to other groups. As a last type, No. 3 was that the students learned from other groups' presentation without any feedback and improved their inquiry. Third, there were five kinds of giving feedback; (1) feedback understanding the inquiry correctly, (2) insufficiency of peer's inquiry without deep thought. (3) on the usefulness of the inquiry, (4) on the scientific and logic validity through critical thinking, and (5) how to develop the inquiry. In these kinds of feedback, the fourth kind of feedback (4) occurred most frequently but the fifth (5) occurred rarely. It means peer review helps students develop their critical thinking ability and teachers should encourage students to give peers feedback of the fifth kind.

This study analyzed the difference in evaluation results in evaluating identical products by applying two different types of evaluating scales, Creative Product Analysis Matrix (CPAM) and Creative Product Semantic Scale (CPSS) by O'Quin and Bessember (1989). As a result, evaluation based on explicit knowledge scored lower than evaluation based on implicit knowledge, implying that the evaluation becomes stricter. When evaluated with CPSS, which as relatively more segmentalized grading criteria, all sub-dimensions of creativity showed low scores, and it show that when evaluator's first impression or personal evaluation standard on the products is firm, they may not be evaluated by the evaluation tools. Gifted education teachers were giving similar evaluations as experts in creative product evaluation, and understanding the product evaluation tool fully in advance before teaching or evaluating products may lead to the generation of newer, more useful and appropriate, and highly creative product with high solvability.

This study is to explore the Pedagogical Content Knowledge of beginning earth science teachers about the porphyritic texture of igneous rocks, and to suggest the teaching device that can prevent a trial and error of students in earth science instruction. We developed an interview guideline concerned with basic perception on the porphyritic texture, formation condition and formation process of porphyritic rocks, teaching and learning on porphyritic rocks for it. And data was collected from 5 beginning earth science teachers (3 high schools, 2 middle schools) through a group discussion method. In result, despite the porphyritic texture can be found at hypabyssal rocks as well as volcano rocks and plutonic rocks, most beginning earth science teachers cognized that it could be found at hypabyssal rocks only by focusing the formation depth of hypabyssal rocks. Also, the formation of porphyritic texture should be considered the factors such as cooling rate, nucleation density, growth rate, growth time, etc. However they mainly reflected the formation temperature and growth rate as it's parameter. Participants have wrongly perceived that a phenocryst necessarily differs from a groundmass on chemical composition. And they are inclined to discriminate phenocryst from groundmass through their chemical differences, instead of grain size.

This study attempts to analyse mathematical thinking and attitude of students related to mathematization in the problem solving process and provide implication of teachers' roles. For this, this study analyses mathematical thinking and attitude by dividing the process of solving problems of triangular array into several steps. And it makes a proposal for teachers questioning which can help students according to steps. Therefore this study results students' mathematization needs various steps and compositive mathematical thinking and attitude when students solve even a problem. From the point of view of teachers who attempt to wean students on mathematization, it is necessary for teachers to observe and analyze how students have mathematical thinking and take a stand for mathematics in detail. It also indicates that it is desirable for students who can not move on next step to provide opportunities to learn on their own rather than simply providing students mathematical thinking directly. Students can derive pleasure from the process of solving difficult problems through this opportunity and realize usefulness of mathematics. Finally this experience can build mathematical attitude and prepare the ground to be able to think mathematically.

The purpose of this research is to explore preservice earth science teachers' understanding of volcanic systems using a modified version of InVEST Volcanic Concept Survey (InVEST VCS, Parham et al., 2010). Results showed that participants' understanding of volcanic concepts was rather limited. Questions requiring only basic content knowledge (e.g., terminology associated with volcano) received high scoring responses, while questions requiring higher order thinking and deeper conceptual connections as the mechanics of volcanic eruption received low scoring responses. Specifically, the prediction of hazards and impacts on the environment appeared to be poorly understood. VCS results can be applied to improve the subject content knowledge as well as the pedagogical knowledge that instructors may use when they assess students' understanding of volcanism within a solid conceptual framework.
