This study tried to look into what are happening in the 'class for the talented in invention' using COS-R developed by VanTassel-Baska. Teaching and learning activities within the classroom were observed and analyzed in terms of teacher's observation and teacher's observation, respectively. Based on results of this study, conclusions are as follows. First, it was founded that there are some commonalities between teacher observations and student observations. Based on teacher observations, differentiated teaching activities considering individual characteristics are rarely observed, and for students, it was true. Therefore, supplying a special training program for teachers are needed in order to make teachers and students engage in changing their teaching and learning behaviors. Second, on the side of teachers, they usually emphasize the importance of curriculum planning and implementation, problem solving, creative thinking et al. However, they barely stress the characteristics of research methods, critical thinking, and considering individual characteristics and the level of intellectual ability. Third, on the side of students, they frequently respond to solving problems and critical thinking at the same degree. On the other hand, systemic efforts of considering individual differences and adapting to them have been less regarded in both teaching and learning. In sum, for the successful 'Invention gifted classroom', establishing an educational environment to consider individually guided instruction and taking a balance among various factors embedded in teaching and learning situation should be required.

The purpose of this study was to develop a rubric for assessing students' scientific argumentation. Through the analysis of relevant literature related to argument in science education for developing rubric, the procedure in development and the category in assessment for rubric were elicited. According to the general procedure in developing rubric, the standard for evaluating the argumentation derived three categories such as a form, contents, and attitude. The form category was further segmented into sub-functions composition, claim, ground, and conclusion in the whole. The category for contents was segmented into sub-functions understanding, credibility, and inference. And the category for attitude was set to sub-functions participatory level and openness. The standard for evaluating sub-functions in each of the categories formed in this way was minutely suggested with five stages. The rubric, which was developed on the basis of literature, was inspected through a regular seminar in one expert in science education and fellow researchers. The rubric, which was developed in the early days, was again modified by being verified on problem and improvement matter after being entrusted to four experts in scientific education. And, the finally-completed rubric indicated to be high with 0.96 in the content validity index by being verified the validity by the four experts in science education. The developed rubric will lead to being able to increase the understanding about demonstration in students, and to being available for being utilized as the criteria for developing the argumentation process program and for evaluating the argumentation activity.

The purposes of this study were to develop and apply on learning on geological field trip utilizing the social construction of scientific model. We developed field trip places by considering not only Orion (1993)'s novelty space but also the achievement standards of 2015 national curriculum. The subjects of the study were 8 in the 'G' science gifted education center. We conducted a study using the theme of 'How was formed Mt. Gwanak?' on 5 lessons including a series of 2 field trip lessons and 3 lessons utilizing the social construction of scientific model. Students participated in pre- and post-test on the understanding of scientific knowledge about formation of mountain. Semi-structured interview was used to analyze students' learning about geological field trip in terms of affective domain. Results were as follows. First, there were 2 places of upper-stream valley and down-stream valley separately. They contained outcrops gneiss, granite, joint in the valley, xenolith, fault plane, mineral in the valley. Second, pre- and post-test and semi-structure interview were analyzed in terms of what scientific knowledge students learned about and how Mt. Gwanak was formed. Seven students explained that Mt. Gwanak was volcano during pretest. Seven students described how granite was formed to form Mt. Gwanak. They also understood geological time scale, i.e., metamorphic rock. Third, the geological field trip was effective to low achievement geoscience students as they engaged in the activities of field trip. Using positive responses on affective learning was effective on learning on geological field trip when utilizing the social construction of scientific model. This study suggests that teachers use an example 'model' on geoscience education. This study also suggests that teachers apply the social construction of scientific model to geological field trip.

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.

This research examines how PBL(Problem-based Learning; PBL) system affects to 'Self-directed learning ability', by developing and applying it to the participants of "Science Cyber Conference" - the web based on-line debating learning program - among those students of the Affiliated Institute of Science gifted education of K University, for 16weeks. With this, also the cognizance of learners for the PBL class process are looked into together. After conducting the program applied with the web-based PBL strategy, the participants 'Self-directed learning ability' showed the remarkable change statistically (p<.05). Especially it showed the meaningful changes in six sections (p<.05), among those subdivided seven sections of 'Self-directed learning ability', with the one exception, 'Self-confidence as a Learner'. They also showed the positive response to the class which adopted the web-based PBL strategy.

The purpose of this paper is to find a method of measuring mathematical creativity reasonably. In the pursuit of this purpose, we designed four multiple solution tasks that consist of two kinds of open tasks; 'tasks with open solutions' and 'tasks with open answers'. We collected data by conducting an interview with a gifted fifth grade student using the four multiple solution tasks we designed and analyzed mathematical creativity of the student using Leikin's model(2009). Research results show that the mathematical creativity scores of two students who suggest the same solutions in a different order may vary. The more solutions a student suggests, the better score he/she gets. And fluency has a stronger influence on mathematical creativity than flexibility or originality of an idea. Leikin's model does not consider the usefulness nor the elaboration of an idea. Leikin's model is very dependent on the tasks and the mathematical creativity score also varies with each marker.

In this paper we investigate several properties and characteristics of the generalized Fibonacci sequence $\{g_n\}$={a, b, a+b, a+2b, 2a+3b, 3a+5b,...}. This concept is a generalization of the famous Fibonacci sequence. In particular we find the identities of sums and the nth term $g_n$ in detail. Also we find the generalizations of the Catalan's identity and A. Tagiuri's identity about the Fibonacci sequence, and investigate the relation between $g_n$ and Pascal's triangle, and how fast $g_n$ increases. Furthermore, we show that $g_n$ and $g_{n+1}$ are relatively prime if a b are relatively prime, and that the sequence $\{\frac{g_{n+1}}{g_n}\}$ of the ratios of consecutive terms converges to the golden ratio $\frac{1+\sqrt5}2$.

In this study, the models described in the textbooks related to floating and sinking phenomena in the chemical domain were evaluated based on the aspect of nature related to the generation of models. To achieve this, we were targeting statement of textbooks from 7th curriculum to 2009 revised curriculum. Analysis of textbooks was performed for science of elementary school (total 2 textbooks) and science of middle school (total 21 textbooks) which dealt with these phenomena. According to the textbooks analysis, characteristics of statement way were (1) No description of the model's prerequisites, (2) Statement based matter viewpoint, (3) Lack of pattern principle, (4) Inadequacy of the case covered. Although the education about the model for the students should be preceded by the education related to the process of model creation rather than the activity using the model, the education about the nature of the model is insufficient. In order to solve this problem, we propose the model statement in textbooks and the development of the model evaluation tool related to model creation.
