프로젝트 학습은 구성원간의 협동을 통해 문제를 해결해 나가는 학습형태로 학습자의 문제해결력을 높일 수 있는 방법이며, 프로젝트 학습에서의 평가는 교사의 조언과 지도를 통해 학생의 학습 능력을 향상시키는데 도움을 준다. 그러나, 협동학습에서는 일명 '무임승차'라는 문제점이 발생할 수 있어 오프라인 상태에서의 학습활동시 교사가 학생 개개인의 프로젝트 학습 능력을 측정 및 관리하기가 정확하게 이루어지기에 한계가 있다. 이에 본 연구에서는 웹상에서 이루어지는 프로젝트 학습시, 학습자에게 효과적으로 조언과 지도를 통하여 학습수행능력을 향상시킬 목적으로 개별 학습자의 프로젝트활동을 효과적으로 평가할 수 있는 평가시스템을 설계하고자 한다. 평가는 프로젝트 중 평가와 프로젝트 후 평가로 이루어지며, 단계별 평가 기준 관점은 Chard가 제시한 프로젝트 활동 평가 준거를 참고하여 정하였고, 루브릭 평가 방법을 도입하여 세 가지 단계로 제시하였다.

The purpose of this study is to improve the effectiveness of Course Embedded Assessment(CEA) program through the development and application of the Program Outcomes Assessment System. This is a methodological study which is developing the Program Outcomes Assessment System based on Web-based CEA and applying it to assess the achievements of students by professors teaching them The Web-based CEA system has been developed by implementing a software development life cycle. First, a demanded survey was conducted for the system development, and the results were applied for developing the Web-based CEA. The CEA was used for assessing the achievement of students by professors charging them. Finally, another survey was performed to evaluate the effectiveness of the CEA in professors who experimented it. By implementing the Program Outcomes Assessment System, it is possible to monitor the achievement of the program outcomes and CQI of individual students at the time of graduation. Also It makes it possible to check the unaccomplished achievements of students, analyze the causes regarding uncompleted works, and find ways to enhance students to improve their ability.

정보화 시대의 요구에 대한 교육적 대응은 학습자 중심의 교육이며, 정보통신기술을 기반으로 한 원격교육이다. 특히 인터넷에서 가장 활발하게 사용되고 있는 웹은 그 특성상 구성주의 학습 원리를 실현하는데 적절한 환경을 제공하고 있으며, 교육 시스템의 변화를 가져오고 있다. WBI(Web Based Instruction)는 웹을 매체로 활용하여 원거리에 있는 학습자를 교육시키는 형태로서 교수자와 학습자간 상호작용을 가능하게 하고 다양한 형태의 학습자료를 제공하며, 공간적 제약을 극복할 수 있다는 장점이 있다. 본 논문에서는 웹에 기반한 교육적 활용의 한 모델로서 학습자의 자기 주도적이고 적극적인 학습을 촉진하기 위한 자기 주도적 학습이론과 학습자의 개인차를 고려한 수준별 학습이론을 적용하여 효율적인 웹 기반 학습이 가능하도록 하였으며 이러한 학습이론을 웹에 기반한 정보처리 기능사 필기시험에 적용함으로써 실업계 고등학교 교육현장의 비효율성과 기존의 문제은행 시스템의 문제점을 보완하여 시험준비에 보다 효율적으로 대비하도록 설계 및 구현하였다.

The purpose of this study is to develop an automatic classification system for recommending appropriate books of 9 enneagram personality types, using book information data reviewed by librarians. Data used for this study are book review of 501 recommended titles for children and young adults from National Library for Children and Young Adults. This study is implemented on the assumption that most people prefer different types of books, depending on their preference or personality type. Performance test for two different types of machine learning models, nonlinear kernel and linear kernel, composed of 360 clustering models with 6 different types of index term weighting and feature selections, and 10 feature selection critical mass were experimented. It is appeared that LIBLINEAR has better performance than that of LibSVM(RBF kernel). Although the performance of the developed system in this study is relatively below expectations, and the high level of difficulty in personality type base classification take into consideration, it is meaningful as a result of early stage of the experiment.

The purpose of this research is to suggest the direction of using blog in e-PBL. In this research we used blog for supporting individual self-regulated learning activity. We distributed space for individual learning and collaborative learning by using blog and community. 39 students participated during the 16 weeks, which includes 8 weeks of traditional e-PBL and 8 weeks of Blog based e-PBL. We conducted questionnaires and interviews, and analyzed learners' reflection notes. Data show learners feel comfortable with using blog in their independent learning activity. And blog activated learners' reflective activity and motivated their self-regulated learning.

본 논문은 사용자 수준에 적합한 맞춤형 학습코스를 추천하여 학습효과를 향상시킬 수 있는 추천모델을 개발하고, 효과분석을 위한 방안을 제시한다. 학습자 개개인의 학습수준이나 학습내용 등에 따라 적합한 학습주제를 선정하여 제공하는 것은 중요하나, 일반적인 추천은 전문가 그룹을 활용한 사람중심의 추천으로 시간이 오래 걸리는 등 자원의 비효율적 한계점[1]을 가지고 있다. 이를 극복하기 위해, TF-IDF를 이용해 단어별 가중치를 계산하여 고빈도 단어를 추출하여 벡터 공간에 배치시키고, Cosine Similarity 기법을 이용해 벡터간의 유사도를 측정하였다. 학습자 프로파일을 분석하고, 학습스킬간의 연관성을 고려하여 맞춤형 학습코스를 추천하기 위해, 워드 임베딩 기법을 적용하였고, 이를 위해 오픈소스 Gensim[2]을 이용하였다. 맞춤형 학습코스 추천 모델의 효과를 분석하기 위한 실험을 설계하고 평가 문항지를 개발하였다.

Major Characteristic of the 7th National Curriculum in science is to provide deep and supplementary learning, depending on the level of each learner. In the level-oriented curriculum, coursewares are used to present teaching materials to various levels. In most coursewares, however, they provide their contents at a uniform level and hence it is hard to expect level-oriented learning. This paper presents learner's modeling for developing student's level-oriented dynamic tutoring system for science class , Instructional module of this system made by component unit is able to be reconstructed dynamically. Learning module is constructed using a hybrid model mixed of Overlay and Bug model. Testing module interprets diagnostic errors to be established by given differentiated weight in accordance with item's difficulty and discrimination. Through ITS student modeling, this system presents various problem solving methods reconstructed by learner's level differentiated.

The purpose of this study is to provide statistical analysis based suggestions on effective methods to take advantage of social network service (SNS) for educational purposes based on investigations of undergraduate students with high utilization of SNS. To achieve this, we conducted an open questionnaire survey and qualitatively analyzed the data using NVivo 10 program. Additionally, to visualize the analysis by education subject of the SNS educational methods, we have divided the data into 3 categories of teacher, student and common area. As a result, our analysis showed that the exchange opinions and discussions, information sharing and learning of contents of questions and answers, surveys, intimacy formation, counseling etc. were of the common area. Furthermore, teacher area included the notice announcement, teaching materials sharing, real-time assessment (quiz), attendance check, assignment grading and feedback, etc. Finally the student area was of project activities (group/individual), prepare and review the shared data, video self learning, peer review and feedback of projects, lecture evaluation, etc.

This study exploratively investigated the cultural disposition of undergraduates in LIS and their collaborative learning. To identify the cultural disposition, this study employed the Triandis' scale identifying four dimensions including horizontal individualism, vertical individualism, horizontal collectivism, vertical collectivism. Additionally, their collaborative learning was analyzed by self- and peer-evaluation surveys. The findings showed that 66.7% LIS students had the horizontal collectivism and their contribution to the collaboration was higher than other groups. Additionally, the gender difference indicated that female students actively participated in the collaboration and gave more contributions than male students. However, the female students had low satisfaction to the collaboration. These results can be used to improve LIS students' collaborative learning.

The purpose of this study is to analyze the satisfaction and effective variables in online learning for low-income students. An Web-survey was conducted to measure its satisfaction and effectiveness. 285 students participated in the study. T-test and ANOVA were used to analyze the data. The result of satisfaction was fairly positive. In addition, there were differences in effectiveness. In specific, the each group of female, elementary school, higher level of achievement, and higher level of self-regulated learning group students showed higher satisfaction than the others. Suggestions and future research are discussed.
