What are the identification criteria elementary school teachers prefer? What are the characteristics of students that teachers consider when nominating them to gifted programs? Will those criteria of identification/nomination differ as to teacher experiences related to gifted education or teacher involvement in the professional development? This study aims to find the answer to these questions. For this purpose, a total of 511 elementary school teachers with a varying degree of experiences with gifted education were recruited from 23 schools in 11 school districts in Seoul. The results show that teachers generally preferred task commitment, creativity, curiosity, and domain specific talents as criteria for identifying gifted students, while perceiving achievement records, total grades, leadership, and general intelligence as less important. Teachers experienced in gifted education or having been involved in professional development perceived curiosity, task commitment, and creativity as more important than teachers without such experiences. The importance-performance analysis of identification criteria indicates that teachers reported high importance on task commitment, curiosity, and creativity, but those factors were less considered in actual nomination. On the contrary, teachers reported low importance on quick learning and achievement(total grades, subject grades), but those were highly considered in nomination. A similar pattern was found in both experienced and nonexperienced teachers although the importance-performance gap was higher for the latter. Implications for teacher nominations and professional development were discussed.

The Purpose of this study is to investigate and suggest a counseling strategy and practice for solving interpersonal problems of elementary school students that elementary school teachers are now confronted with. In this study, first of all, the actual conditions of interpersonal problems of elementary school students were examined focusing on interpersonal aggressions(violence and victim). The features and problems of existing approaches for solving interpersonal problems of elementary school students were indicated. Although existing approaches for solving interpersonal aggression problems took temporary and external changes, they failed to notice psychological hurts that victims and aggressive victims got. As a fundamental and systematic way for overcoming problems of existing approaches, forgiveness counseling education based on empirical-scientific forgiveness researches was discussed. The Purpose of forgiveness counseling education is to make victims(aggressive victims) overcome the negative responses derived from interpersonal conflict(hurts and victims) and to facilitate them to response positively through experiencing forgiveness psychological process. Lastly, necessary assignments and topics to use forgiveness counseling education as an effective personality education approach were discussed.

기후변화는 범지구적으로 당면한 과제로서 국제적으로도 이에 대한 저감 완화대책 수립 및 시행에 힘쓰고 있다. 이러한 세계적 관심에 따라 최근 우리나라도 국가 물 안보에 대한 보고서 등의 개정에 관심을 기울이고 있는 실정이다. 그러나 이러한 당면한 문제에 대한 계획을 수립하기 위해서는 무엇보다도 직면하고 있는 사실에 대한 이해가 필요하다. 특히 우리나라의 경우에는 비록 국토가 좁은 나라에 속하지만 호우의 계절적 지역적 편차가 큰 편이기 때문에 무엇보다 지역별 변화에 대한 연구가 필요한 실정이다. 지금까지의 수문학 분야의 기후변화에 대한 영향 연구는 대부분 유역을 중심으로 수행되어 왔다. 이는 자연현상을 모의하기 위해서이나 실제적으로 국가예산 계획수립 및 투입은 주로 지자체단위로 이루어지기 때문에 지자체별 영향에 대한 연구도 매우 중요하다. 따라서 본 연구에서의 지역적 범위는 지자체단위로 하였다. 이러한 지역별 분석의 범위는 최소 단위의 의사결정자들을 위한 범주가 되면 이상적이겠지만 실제적으로 이는 여러 가지 이유로 어려운 점이 있기 때문에 본 연구에서는 우리나라의 광역지자체를 공간적 범위로 설정하였다. 또한 기후변화 시나리오는 IPCC(Intergovernmental Panel on Climate Change) 4차 보고서의 탄소배출 시나리오 중 널리 사용되고 있는 3종(A1B, A2, B1) 선정하였으며, GCM은 4종(CNRM: CM3, CSIRO: MK3, CONS: ECHO-G, UKMO: HADCM3)을 적용하였다. 최종적으로 각 광역자 치단체별-시나리오별-GCM 별로 4개의 기간 구간 (2080-2009, 2010-2039, 2040-2069, 2070-2099)으로 나누어 평균 일최대강우량 및 연총강우량의 변화를 분석하였으며, 이러한 분석법은 일본 국토교통성의 경우 이러한 방법에 일최대강우량에 적용하여 미래 기후변화로 인하여 치수안전도 변화 분석에 활용한 바 있다.

The paper explored the limitations of anecdotal records in kindergarten and presented the challenges toward authentic records. The data was collected from 7 teachers working at private kindergartens through focus group interviews (FGI) and individual follow-up interviews. The participants' conversation in the FGI and their responses in the individual interviews were analyzed according to the principles of thematic coding. The participants described the barriers from recording a child anecdote in private kindergarten and at the same time their voices implied the possibilities to overcome the difficulties. All descriptions of the participants were converged on the 3 themes with rhetoric of "from A to B". For becoming anecdotal records in kindergarten, in summary, the records at the present should be changed 1) "from formal and faithless documentation to fluent resources of children's development", 2) "from disconnectedness between the records and curriculum to recursive circulation for improving pedagogical realities", and 3) "from canned documentation written by a struggling teacher to meaningful writing produced by a teacher like researcher".

Recently, there has been a lot of research on utilizing Language Models, and Large Language Models have achieved innovative results in various tasks. However, the practical application faces limitations due to the constrained resources and costs required to utilize Large Language Models. Consequently, there has been recent attention towards methods to effectively utilize models within given resources. Curriculum Learning, a methodology that categorizes training data according to difficulty and learns sequentially, has been attracting attention, but it has the limitation that the method of measuring difficulty is complex or not universal. Therefore, in this study, we propose a methodology based on data heterogeneity-based Curriculum Learning that measures the difficulty of data using reliable prior information and facilitates easy utilization across various tasks. To evaluate the performance of the proposed methodology, experiments were conducted using 5,000 specialized documents in the field of information communication technology and 4,917 documents in the field of healthcare. The results confirm that the proposed methodology outperforms traditional fine-tuning in terms of classification accuracy in both LoRA fine-tuning and full fine-tuning.

What does mean the statement that scientific reasoning is logical? In this study, we clarify the logical structure of the scientific explanation, prediction and the process of hypothesis testing. To simplify and identify the structure of scientific explanations and prediction more clearly, we used syllogism and presented various concrete examples. Especially, we showed that the logical structure of scientific explanation was well reflected in dynamics. Based on this analysis, it can be said that the deficit of students' understanding of dynamics is because that many scientific activities are focused on prediction rather than explanation. To explain the process of hypothesis testing, we reinterpreted the Wason's selection task as two stages: the process of prediction of experimental phenomena based on the presented hypothesis, and the process of the hypothesis testing based on the predicted experimental phenomena. And we suggested the reason of the logical fallacy of 'affirming the consequent' in science was because that many scientific relationships between the variables is one-to-one relationship, and compared this suggestion with the Lawon's multiple hypothesis theory. To check out the effect of content on the deductive reasoning, we reviewed some researches about psychology and psychology of science. And to understand the role of deductive reasoning in student's scientific activities, we reviewed researches about the analysis of students' responses in the task of conceptual change or evaluation of evidence and so on.
