초등학교 영재들은 여러 사설 교육기관이나 국립기관 그리고 개인 교습을 통하여 많은 양의 선수학습을 행하고 있다. 이들 중 일부는 방법과 이유를 아는 관계 이해를 하기보다는, 주어진 규칙을 적용하여 정답을 찾아내는 도구적 이해를 하고 있다. 그들은 수학을 능동적이기보다는 수동적인 입장에서 받아들이기에 새로운 수학적 지식을 창출하지 못하는 성향을 강하게 보이고 있다. 이에 본 연구자는 이러한 문제의 해결을 위해 초등학교 영재들이 가지고 있는 수학적 스키마와 선생님들이 가르치는 스키마 사이의 간격에 초점을 맞추어 연구하였다. 대전에 있는 영재교육기관에 등록된 초등학교 3학년 영재들을 대상으로 하여 연구한 결과, 스키마와 스키마 사이의 간격이 멀수록 학생들이 방법과 이유를 아는 관계적 이해를 하기보다는 주어진 규칙을 적용하여 정답을 찾아내는 도구적 이해를 하고, 그 간격을 줄일수록 수학에 흥미를 느끼고 고학년의 수학내용까지도 스스로 파악하고 이해하려는 성향이 나타난다는 사실을 발견하게 되었다. 그 간격이 적을수록 학생들은 교사로부터 학습받은 내용을 자신의 지식으로 재구성하여 새로운 문제에 적용을 쉽게 하였다. 본 발표에서는, 학생들의 수학적 스키마와 선생님들이 가르치는 스키마 사이의 간격을 줄이는 것이 학생들이 수학을 관계적 이해를 하는데 큰 도움을 줄 수 잇음을 보이려고 한다.

This study investigates the actual domestic and overseas cyclewear wearing conditions for male high school cyclists. The study results provide factors and degree of dissatisfaction as basic data for cyclewear development. This study was conducted on 35 male high school cyclists (freshman to seniors) by a questionnaire and interview method. Study results were: Male high school cyclists considered functionality as most important when they bought cyclewear and the brand they most often bought was a cheap domestic brand. Dissatisfaction with the crotch, thigh circumference and minimum leg circumference was higher than other parts during wearing. A cyclist is more sensitive to wear because they require more lower body motion than other parts. Cyclewear should be: less transformed even by frequent laundering, made of breathable material and use a sewing technique that minimizes air resistance and increases fit the body. Functional pads ergonomically designed with high tactile materials should be developed to prevent 'saddle sore' and groin soreness region that happens because of a lower body bending posture when cycling. A follow-up study is recommended to further develop excellence in cyclewear functionality and dimension suitability for male high school cyclists through the size system.

The purpose of this study was to develop a concept test tool for seasonal change with reliability and validity, and to objectively observe and analyze sub-concepts and misconceptions related to the concept of seasonal change to explain the relationship between variables. The development process of the conceptual change concept inspection tool consisted of the development of the inspection tool development plan, the development of the inspection tool draft, the modification of the preliminary inspection and inspection tools, the development of the final inspection tool, and the implementation of this inspection. The developed test tool can be used to provide students with appropriate learning and help by examining students' degree of seasonal change concept formation and analyzing the cause of the difficulty in concept formation. As a result of regression analysis of 198 students in 6th grade using the developed test tool, it was found that the understanding of pre-learning concept and correction of misconception had a statistically significant effect on the concept learned in the seasonal change unit, and misconception had greater effect. Correction of misconceptions had a significant effect on students above the average score among the two sections created and cut based on the average score, and on the students below the average score, the understanding of pre-learning concept had a significant effect.

본 연구는 수학 교사가 수학 교과에 대한 학습부진 학생의 이해와 적절한 교수-학습 방법의 탐색을 위한 기초 자료를 제공하기 위해 두 가지 유형의 질적 자료를 중심으로 자료를 수집하고 심리검사, 일반 학습습관, 수학 학습습관, 수학 교과에 대한 태도 등 4가지 선문지를 사용하여 여고생을 대상으로 부진요인 분석에 그 목적을 두었다. 본 연구에 따르면 대표적인 부진 요인은 의문 해결을 위한 의지 결핍과 장기 기억방법을 알지 못하고 수학교과목 자체를 싫어하는 경향이 있는 듯 하였다. 스스로 수학 문제를 풀 수 없다는 선입감 때문에 해답을 보고 문제를 풀게 되고, 검산을 하지 않는 특성을 보였다. 이들 수학 학습부진 학생들을 지도할 때는 선수학습을 반드시 확인하는 수업을 고려해야 하며, 수학적 의사 소통 능력 등 보다 수학적인 내용과 과정에 대한 후속 연구가 필요하다고 본다.

This study attempted to illustrate in-depth light on the process of experiencing the campus life of university life of students specialized in golf who are forming new exercise culture in a transitional state students based on the grounded approach. For this, it selected 10 athletic students as research participants majoring in golf in A University in Chungcheong-do and collected data through in-depth interviews. As for the data analysis, the coding paradigm was composed to derive concepts and clarify the relations between concepts according to the grounded theoretical analysis suggested by Strauss and Corbin (1990), and the research results are as follows: First, 117 concepts, 16 subcategories, and 10 upper categories were deducted in the open coding. Second, the causal conditions were categorized into "University Life of Contactless Classes," contextual elements into "Practical Exercise," and "Participation in Classes," and the central phenomenon was regarded as the "Meaning of University Life as a University Athletic Student (golf)." As a result of reviewing the process of exercise and study at the same time, the conditions of arbitration were summarized as "Relation Formation" and "Ability Improvement," and the action/interaction strategies were categorized as "Academic Research" and "Negative Thinking," and at last, the results were composed of "Looking Back at the Past University Life," "Identity," and "Future Design." Based on these research results, the model of doing exercise and study at the same time of the university athletic students (golf) was categorized by the grounded theoretical paradigm procedure, and the university athletic students (golf) continued their university life without rest as their exercise life was influenced positively by academic life, and in addition, policy implications for enhancing the competency of student athletes who can encompass both exercise and study were presented.

Seligman argues that an optimistic athlete wins based on a study of US professional baseball and professional basketball players.(trans. Choi, 2008). So, the purpose of this study was to investigate whether optimism can predict the performance of badminton youth representatives. 60 high school students were divided into two groups according to their performance. We used the revised Life Orientation Test (LOT-R) developed by Scheier, Carver and Bridges(1994) and translated into Korean version by Shin Hyun-sook(2005). For this study, the data were analyzed by frequency analysis, reliability analysis, and independent t - test. As a result, there was a statistically significant higher level of optimism in the excellent group than in the non-excellent group. So, in order to improve sports performance, we need psychological skills training that can improve optimism as well as physical training and skills training.

전통적인 수학교육은 간단한 수학적 사실을 이해하고 활용하는 측면에 있어서는 효과적일 수도 있지만, 수학적 개념, 원리, 법칙을 학생 스스로 탐구, 발견하고 창조하는 능력을 기르는 데는 적절하지 않다. 이러한 능력을 기르기 위해서는 학생들 스스로가 관찰, 조작, 분석, 종합하는 활동을 강화할 필요가 있다. 구체적 조작물을 학습도구로 활용하는 경우, 수학 학습에 대한 흥미와 자신감을 길러 주고, 자신의 수준에 맞는 내용을 자기 주도적 학습을 통하여 성취감을 가지게 하며, 학생 스스로 탐구 활동을 활발히 하는데 도움이 된다. 삶의 질이 급격히 향상되는 정보사회에서는 사이버 공간의 등장으로 공간감각 기능의 필요성이 더욱 절실한 바, 현행 수학교과서에서 제공되는 각종 공간 도형들은 3차원 공간에서 이루어지지 않고 평면도형으로 처리함으로써 아동의 도형인지 능력 향상에 큰 효과를 기대하기 어렵다. 이에 본 연구에서는 아동의 인지발달 단계를 고려, 도형인지능력 향상을 위한 선 및 점대칭 관련 동기유발, 선수, 기본, 보충, 심화, 평가, 도움말 관련 프로그램을 개발, 적용한 결과 학습자의 동기가 유발되고, 도형 인지능력 향상에 유의미한 결과를 얻었다.

SENKs (Students who Emigrated from North Korea to South Korea) are exposed to the general problem of Su-Po-Ja(mathematics give-uppers) as well as their own difficulty in learning mathematics. In this study, we conducted the FGI (focus group interview) in order to examine the recognition on mathematics teaching and learning in South Korea with 6 SENKs and 3 teachers who teach the SENKs. As a result, it was found that SENKs' had difficulties in understanding math because of the differences in math terminology used in South and that in North Korea, the unfamiliar problem situation used in math lesson, and the shortage of time for solving math problem. And the teachers reported that they had difficulties in teaching great deal of basic math, SENKs' weak will to learn math, and SENKs' lack of understanding about problem situation because of the inexperience about culture and society in South Korea.
