본 연구는 중학생을 대상으로 협동 학습에서 사용하고 있는 기존의 집단 구성과는 달리 학생들의 학습 양식에 따라 집단을 구성하여 협동 학습의 효과성을 보이고자 하였다. 학습양식(Learning Style)에 따라 집단을 구성한 협동 학습의 결과는 다음과 같다. 첫째, 학습양식에 따라 구성한 협동 학습 집단( I, II, III, IV)이 일반학습 집단(V)에 비하여 수학 성취도에 있어서 유의한 효과를 보였다(p<.001). 둘째, 학습양식에 따라 구성한 협동 학습 집단( I, II, III, IV)이 일반학습 집단에 비하여 수학에 대한 긍정적인 태도로의 변화가 있었다(p<.001).

Currently, most of the science and engineering students who enter the university are required to take general chemistry and general chemistry experimental subjects. However they have different learning bases about learning basic science subjects. Regarding college entrance examinations, the current system is used for selection, so they have different levels of basic knowledge. But, without considering this situation, all of the students in science and engineering are participating in the same basic science class, some learners are relatively easy to adapt to learning, while others experience extreme difficulties and suddenly give up. This is true. The purpose of this study is to develop a scale to measure the ability to learn general chemistry of freshmen in science and engineering at H University in the Seoul Metropolitan area and to analyze what kind of learning backgrounds are related to learners. The results show that gender and major are not related to general chemistry learning major, and it we found that there is a close relationship to the relationship between their major and chemistry, the level of the chemistry learning in the high school, and the selection of chemistry in college entrance examinations. In addition, it was found that the degree of feeling that pre-learning is beneficial to current learning and that it is common with current learning is also a factor related to general chemistry learning aptitude. Therefore, in this study, we propose two ways of presenting and promoting a guide for learning by majors, and establishing a step-by-step learning system considering the level of students.

This study compared the difference of learning style, self-regulated learning, learning flow, analyzed the learning style impact on self-regulated learning and learning flow between gifted and normal student. The subjects of this study were 118 sixth grade gifted students and 124 general students who showed academic achievement of the same level. According to the results of this study, gifted elementary children had more than the general independent, competitive, participatory learning style and they used personal, behavioral and environmental self-regulation strategies more often. Also they had a higher degree of learning flow than the general. Both gifted and general students, the more independent and participatory learning style, the more increased self-regulated learning and learning flow. And the more used self-regulated learning, the more increased learning flow. The learning flow of the gifted children was higher the more independent, the more participatory, the more used behavioral and personal self-regulated learning strategies. The learning flow of the general elementary children was higher the more participatory, the more used environmental and personal self-regulated learning strategies.

본 연구에서는 고등학교 학생을 대상으로 탐구학습 과정에서 수학적 태도와 수학 창의성에 어떤 변화가 일어나는지를 살펴보았으며, 그 결과는 다음과 같다. 첫째, 문제해결방법에 탐구학습을 투여한 학습집단은 일반 학습집단보다 수학 창의성에 있어서 유의미한 효과를 보였다(p<.05). 둘째, 탐구학습 집단과 일반학습 집단의 수학적 태도는 사전 및 사후의 두 검사에서 모두 유의미한 차이를 보이지 않았다(p<.05).

The present study was investigate the effects of feedback on mathematical achievement and attitude toward mathematics. Referring to the improvement of mathematics achievement, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there found no significant differ between group I and II(p>.05). As for the poor level of mathematics achievement, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there for fine level, found no significant differ between feedback group(group I and II)and the normal learning group(group III)(p>.05). Referring to the improvement of attitude toward mathematics, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there found no significant differ between feedback groups(group I and II)and the normal learning group(group III)(p>.05). As for the level(find or poor) of mathematics achievement, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there found no significant differ between feedback group(group I and II) and the normal learning group(groupIII)(p>.05).

본 논문에서는 독립변수들의 차원을 감소시켜 일반회귀 신경망의 성능을 개선하는 방법을 제안하였다. 제안된 방법에서는 적응적 학습 알고리즘의 주요성분분석 기법을 이용하여 독립변수 패턴의 특징을 추출하고 이를 일반회귀 신경망의 학습데이터로 이용하였다. 이는 주요성분분석 기법이 가지는 대용량의 입력 데이터를 통계적으로 독립인 특징들의 집합으로 변환시키는 속성을 살려 학습데이터의 차원을 감소시킴으로서 고차원의 학습데이터에 따른 일반회귀 신경망이 가지는 제약을 해결하기 위함이다. 제안된 기법의 일반회귀 신경망을 3개의 독립변수 패턴을 가진 암모니아 제조공정문제와 10개의 독립변수 패턴을 가진 자동차 연비문제에 각각 적용하여 시뮬레이션한 결과, 기존의 일반회귀 신경망에 의한 결과와 비교할 때 더욱 우수한 학습성능과 회귀성능이 있음을 확인할 수 있었다. 그리고 커널함수의 평활요소 설정 면에서도 우수한 특성이 있음을 확인할 수 있었다.

The purpose of this study is to provide the basic pedagogical resources for designing the optimum teaching and learning environment in e-Learning through the survey study on learning behavioral styles (LBS) of the gifted students and ordinary students who have experienced e-Learning. And the major results of the study are as follows: The Major field made a very strong difference to the learning behavioral styles between the gifted students and the ordinary students in e-learning environment. On the basis of the study, the LBS sequence of gifted students is the 'passive learning behavioral style', 'environment-dependent and self-directed learning behavioral style', 'positive and cooperative learning behavioral style', 'environment-independent and self-directed learning behavioral style', and the LBS sequence of ordinary students is the 'passive learning behavioral style', 'positive and cooperative learning behavioral style', 'environment-dependent and self-directed learning behavioral style', 'environment-independent and self-directed learning behavioral style'. Simultaneously, there are some individual difference in the learning behavioral style by gender, grade, and the time of using computer between the gifted students and the ordinary students.

The Purposes of this study were to compare the level of study habits and test anxiety between gifted middle-school students and non-gifted and to find out the correlation between study habits and test anxiety in two groups. The total participants of this study were 437 middle school students. One hundred eighty three students (127 boys, 56 girls) belonged to gifted group who were enrolled in Cyber Education Center for Math & Science Gifted Students of KAIST in Daejeon. And two hundred fifty four (128 boys, 126 girls) were non-gifted group who were from the middle school in Seoul City and Gyeonggi province. The results revealed that the level of study habits of gifted middle school students was higher than that of non-gifted. And gifted group felt lower level of test anxiety than non-gifted group. Additionally gifted boys showed significantly higher level of study skills application behavior than gifted girls.

The purpose of this study was to compare the difference of semantic network about sedimentary environment between science gifted students and non-gifted students through field trip. The fifteen high school science gifted students and non-gifted students were participated in the field trip for this study. The geological field trip was performed in Chaseokgang, which suitable learning place for sedimentary environments. Data included field trip observation and students' inquiry activity reports. The inquiry activity reports were analyzed using the semantic network analysis method. The results of this study were as follows: First, the semantic network of science gifted students was larger and complex structures than that of the non-gifted students. Second, science gifted students were interpreted that changes of sedimentary environment was connected with the sorting and the roundness. On the other hand, semantic network of non-gifted students were become fragmented because they were not interpreted sedimentary environment related to scientific concepts.

본 논문에서는 신경망과 유전자 알고리즘의 장점을 결합하고, 개선된 유전자 알고리즘 기반의 역전파 신경망 알고리즘을 이용한 신경망 학습 효과를 살펴 본다. 유전자 알고리즘을 이용한 신경망 학습은 비선형 함수를 이용하여 발생시킨 모의 자료를 통하여 수행하고 학습 수렴의 정도와 학습 속도 등을 비교할 수 있는 모의실험 결과를 일반 신경망 학습 결과와 함께 제시한다. 모의실험의 결과로서 유전자 알고리즘을 적용한 신경망 제어기가 일반 신경망 학습 결과보다 수렴 정확도 및 학습 속도에서 더 좋은 결과를 나타내 주고 있다.
