설명 기반 학습은 시스템 성능향상에 필요한 탐색 제어 지식을 학습하는 방법으로 많이 이용되고 있다. EBL은 과거의 문제풀이 과정을 일반화하여 학습한 다음 이와 유사한 상황이 발생할 경우, 문제풀이를 거치지 않고 학습된 해답을 신속하게 제시하여 성능을 향상시킨다. 그러나 새로운 문제 해결이 과거 문제 풀이 해답에 의존할 경우, 그에 대한 해답을 신속히 구할 수는 있지만 해답의 질은 학습 결과에 의존하지 않을 때보다 오히려 못할 수 있다. 이러한 현상을masking효과라고 한다. 본 논문에서는 의존성 구조를 학습, 이용하여 이러한 masking 효과를 축소하고자 한다. 의존성 구조는 현 상태에서 선택된 연산자가 이후의 문제 풀이에 끼치는 영향을 포함하는 구조로서, 이후 유사한 상황에 대해 선택될 연산자의 적합성 및 효율성을 평가하는 기준으로 사용될 수 있다는 점에서 masking 효과를 축소할 수 있다.

이 연구는 실무능력이 중시되는 맥락에서 유용한 능력기반 학습환경의 구축방안을 모색해보고, 그 효과성을 실증적으로 탐색하는데 목적이 있다. 이를 위해 기존의 교수설계 패러다임의 발전동향을 토대로 능력기반 학습환경 구축원리를 도출하고, 이른 토대로 일반대학의 교직과목의 하나를 선정하여 구체적인 교수학습 환경을 개발하고, 기본적 실험설계의 틀에 그 효과성을 분석해 보았다. 그 결과 원래 해당 과목이 지향한 3개의 능력 중 2개 능력에서 실험집단이 비교집단보다 향상의 가능성을 보였다. 후속 연구에서는 이 학습환경 모형의 정련화와 아울러 효과검증 방법론을 보다 정련화하고, 표본수 증대를 통한 통계학적 검증이 요청된다.

The objective of the present study is to systematically examine the effects of on the cognitive and affective domains of elementary, middle, and high school students by conducting a meta-analysis. To this end, this study selected 31 research papers that had analyzed the effects of applying, and performed a meta-analysis of the findings presented in each research paper. The results obtained from the meta-analysis are presented as follows. First, both the collaborative learning program and the peer tutoring program for underachieving students in math manifested an above average size of effect in the cognitive domain. In particular, the effect was the greatest at the elementary school level, and out of the two programs, peer tutoring was identified to have a sizable effect. Second, both programs displayed an above average size of effect in the affective domain, and peer tutoring was identified to have a higher effect than collaborative learning. In addition, when the programs were compared based on school levels, the size of effect was highest at the elementary school level followed by middle school and high school, in that order. When compared based on the criteria of the affective domain, self-efficacy in math, learners' attitude toward math, and learners' interest in math were identified to. Finally, this study presented suggestions for teaching underachieving students in math and conducting follow-up studies based on the analysis results.

When human beings acquire and develop knowledge through education, their prior knowledge influences the next learning process. As this is a fact that should be considered in machine learning, we need to examine the effects of controlling the order of training sequence on machine learning. In this research, the role of the supervisor is extended to control the order of training samples, in addition to just instructing the target values for classification problems. The supervisor sequences the training examples categorized by SOM to the learning model which in this case is MLP. The proposed method is distinguished in that it selects the most instructive example from categories formed by SOM to assist the learning progress, while others use SOM only as a preprocessing method for training samples. The result shows that the method is effective in terms of the number of samples used and time taken in training.

This study purpose to empirically investigated the effects of Learning Presence perceived by university students at general universities who took Remote Classification in the first semester of 2020 on Learning Outcomes and the mediating effects of Learning Immersion. A total of 293 students were surveyed by conducting an online survey for about a month from Sep. 15, 2020, targeting college students attending general universities in Seoul and Gyeonggi-do. The results of the study are as follows: First, Learning Presence had an effect on Learning Immersion and Learning Outcomes, and Learning Immersion had an effect on Learning Outcomes. Second, Learning Immersion had a mediating effect on the relationship between Learning Presence and Learning Outcomes. This study is meaningful in that it verified the relationship between Learning Presence, Learning Outcomes, and Learning Immersion perceived by college students who took Remote Classification in COVID19 response dimension.

The purpose of this study is to examine the effects of team efficacy and perceived loafing on learning outcome in team-based project learning. For this purpose, questionnaire survey was conducted to 58 students who enrolled the adolescent welfare class in 2019 at H University. A hierarchical regression analysis was conducted for the effects of team efficacy and perceived loafing on learning outcomes and the interaction effect between two variables. Main results of this study were as follows. Team efficacy had a positive effect on learning outcomes. Second, perceived loafing did not have a statistically significant effect on learning outcomes. Third, the interaction effect of perceived loafing and team efficacy on learning outcomes was significant. In particular, the negative effect of perceived loafing on learning outcomes was reduced by team efficacy. Based on the research results, a plan to increase the learning outcome of team-based project learning was discussed.

This study is prepared to provide fundamental data for constructing learning system to reinforce learning facilitation and improve learning effect for adult college students by testing the medium effect of learning motivation in the relation of social support, service quality of university education, and learning engagement. For this objective, A survey was conducted with 573 adult college students attending 2-to-3-year colleges and universities located in Daegu metropolitan City and Gyeongsangbuk-do. The analyzed research results are as follows. First, learning motivation had partial medium effect in the relation of social support and learning engagement. Second, learning motivation seemed to have complete medium effect in the relation of service quality of university education and learning engagement. The above research results suggest that continuous development and efforts are needed to establish various support systems and improve educational services in order to increase adult college students' immersion in learning.

최근 스마트 컴퓨팅 시대를 맞아 스마트 러닝 시스템에 대한 관심도가 급증하고 있다. 스마트 러닝의 개념은 크게 2가지로 스마트 단말기를 이용한 학습 방법과 학습을 위한 스마트 학습 기법으로 나누어 볼 수 있다. 스마트 학습 기법은 학습자에게 좀 더 효율적이면서 학습의 효과를 증대시키기 위해 학습자의 성향과 학습자의 프로파일, 학습 상황 등을 인지하여 분석하고 적용할 수 있는 기법을 말한다. 본 논문에서는 학습자에게 스마트 러닝을 위한 스마트 학습 기법을 적용한 시스템 설계를 제안하고자 한다. 본 연구에서 제안하고 있는 스마트 러닝 시스템은 학습자에게 적합한 교수학습 모형을 자동으로 적용하여 학습의 효과를 극대화하고, 학습의 유형과 학습 패턴의 변화에 따라 시스템이 학습자에게 지능적으로 대처할 수 있도록 하는 것이다. 교수학습 모형이 학습자에게 자동변화 되기 위해서는 학습자의 성향분석 그리고 형성평가, 사후평가 등의 데이터 분석을 수집하고 자동으로 분석하여 적용 할 수 있는 스마트 학습 에이전트(SSA:Smart Study Agent)가 필요하다. 따라서 본 논문에서는 SSA 설계를 기반으로 스마트 러닝 시스템의 필요성과 향후 연구 발전에 따른 이러닝(e-learning) 교육 혁신에 기여하고자 한다.

기존의 텍스트만 제공하던 학습방법에서 발전해 텍스트, 이미지, 사운드 동영상 자료를 제공함으로써 시각적 청각적인 학습효과를 증가시킬 수 있었다. 하지만 많은 경우 2차원 화면상에 문자나 사진 정보만을 제공함으로써 일상적이고 수동적인 학습에 지나지 않았다. 최근에 들어서는 이러한 문제를 극복하려는 한가지 방법으로서 가상현실을 이용한 체험학습을 통하여 보다 능동적이고 효과적인 교육을 시도하려는 연구가 진행되고 있다. 따라서 본 논문에서는 PC상에서 몰입감을 느낄 수 있는 HMD(Head Mounted Display)와 3차원 마우스를 사용하여 가상현실의 태양계를 탐험하고 이를 바탕으로 학습활동을 함으로써 학습 효과를 높일 수 있는 가상천체 학습 시스템을 구현하였다.
