지난해부터 인터넷 분야에서 가장 확실한 수익 모델을 갖춘 사업 분야로 e-Learning 분야가 손꼽히면서 많은 온라인 교육 서비스가 우후죽순처럼 등장해 이미 1,000여 개의 서비스가 각축을 벌이고 있다. 그러나 e-Learning은 무엇보다도 학습용 컨텐츠의 품질이 그 성패를 좌우한다 할 때 한국의 온라인 학습 컨텐츠의 품질은 부실하기 이를 데 없다는 게 중론이다. 이는 S/W 공학에서 S/W 품질 보장을 위해 개발 방법론이 중요한 것으로 인식되는 것과 이를 지원하기 위한 Method II등 여러 도구들이 보급되고 있는데 비해 학습 컨텐츠는 그 중요도와 개발이 복잡하고 정교함이 요구됨에도 불구하고 개발 방법론에 대한 인식과 개발방법론을 지원하기 위한 도구가 없음에 기인하는바 크다 할 수 있겠다. 아직까지 국내에서는 MacroMedia Director나 ToolBook, Authorware등 일반적인 저작 도구나 웹 기반의 컨텐츠를 제작하는 Dreamweaver등의 HTML Editor만 있으면 컨텐츠가 만들어 질 수 있는 것으로 착각하고 있는 경우가 많다. 교육 학습용 컨텐츠의 개발 주기를 살펴보면 요구 분석->교수 설계->저작->평가->배포의 단계를 거치게 되는데 이때 학습 컨텐츠의 품질은 사실 요구 분석과 교수 설계 단계에서 결정되게 되며 이 학습 컨텐츠의 품질을 결정하는 단계에서는 IT 분야 지식보다는 오히려 교육 공학적 지식이 더욱 요구된다. 그러나 현실적으로 이 단계의 절차적 복잡성과 전문성으로 인해 거의 대부분의 학습 컨텐츠들이 제대로 개발 주기를 거치지 못하고 검증되지 않은 스토리 보드에 의한 저작 단계로 바로 돌입하고 있는 것이 한국의 실정이라 하겠다. 따라서 본 프로젝트에 의해 개발 된 교수 설계 도구는 교육/학습 컨텐츠의 품질 보증을 위한 방법론인 교육 공학의 체제적 교수 설계 이론 Model (Instructional System Design Model), 특히 그 중에서도 이 분야의 사실상의 표준 이론(de facto standard)인 Dick & Carey 교수와 Gagne 교수의 인지주의 ISD Model을 기반으로 정교한 교수 설계와 코스 맵 설계를 가능하게 함으로써 학습 컨텐츠의 품질 보증 활동을 지원 할 수 있는 도구로 개발하였다. 특히 Linux 기반에서 PHP로 개발 함으로써 Platform에 구애받지 않은 사용 환경을 구현 하였으며 향후 많은 e-Learning Platform에 교수 설계 모듈로 장착 함으로써 기존의 e-Learning Platform들의 가치를 높일 수 있는 계기가 될 것으로 생각한다.

The purpose of this study is to derive a curriculum environment for operating various student-centered teaching and learning methods, and the following results were derived: First, most of the lectures, discussions and consultations, data search, report preparation, presentation, work exhibition, and others were commonly derived, regardless of the types of long-term and short-term project classes for each subject. In particular, the necessity of operating various classes at the same time was suggested, indicating the need for an integrated teaching and learning operation environment in the unit subject class. Second, considering that practical classes are linked concurrently to lectures and discussion classes to conduct one subject class, it is necessary to switch to a specialized curriculum system that allows various classes such as lectures to be carried out at the same time. Third, as a result of grasping the appropriateness of the space size of the subject class for realizing different class types in the future, it can be seen that the space size of the practice room, including the space for practice and the area for exhibition, should be expanded. Based on the research results, the spatial environment for the operation of future teaching and learning classes is based on the public curriculum classroom system, and whether professional curriculum classes, such as lecture rooms and discussion and presentation rooms, are secured according to the number of students.

I studied on the relations of constructivism and school library assisted instruction in this paper. Constructivism is the most important goal of the modern schooling. In constructivism they insist that knowledge is constructed by the learner individually and subjectively. So in constructivism they focus their attention on setting authentic environment of learning for each individual learner. Constructivism was developed into the learner-centered instruction in schooling nowadays. In constructivism the following instructions are very important for achievement its' goal ; problem based learning, project based learning, discussion based learning etc. These instructions are supported commonly by resource based learning. Educational resources are managed in school library totally. School library assisted instruction is the most effective one for resource based learning. And information literacy instruction by teacher librarian relates closely meta cognitive learning of reflections in constructivism. School library assisted instruction is the essential element for the practice of constructivism in schooling.

This study investigates the influence of project-based learning method on the problem-solving ability and communication ability of students taking the 'Reading Guide' course in Library and Information Science(LIS). During this study, two tests measuring students' problem-solving ability and communication ability were conducted, containing 30 items divided into 5 steps of problem-solving processes and 45 items divided into 15 categories of communication ability, respectively. By utilizing the correspondence sample T-test during this study, significant differences were found in the 5 steps problem-solving processes. However, no difference was found between the pre-test and the post-test results in all 15 categories of communication ability. Subsequently, an in-depth interview was conducted, inquiring into the students' perspectives on the difficulty of attending classes, the content of lectures, the appropriateness of assignments, the validity of the evaluation method, the relationship with their team members, and the benefits acquired from completing the projects. Finally, an intensive analysis was conducted in the categories of problem-solving ability and communication ability.

In order to improve computational thinking, elementary schools have been using 'Scratch' to provide basic programming education. However, the study on evaluation of computational thinking is at an early stage. Therefore, this study evaluated the conceptual level of computational thinking using the scratch code analyzing. For this, Dr. Scratch was used to analyze 179 scratch projects. The results showed that the conceptual level of computational thinking of most elementary students was at the developing level, and that it varied according to gender and production style, showed the lowest level of logic and abstraction, and improved computational thinking during programming. This study is meaningful in that it provides implications for the improvement of teaching methods and self-directed evaluation in learning.

Software Defect Prediction (SDP) is a field of study that identifies defective modules. With insufficient local data, a company can exploit Cross-Project Defect Prediction (CPDP), a way to build a classifier using dataset collected from other companies. Most machine learning algorithms for SDP have used more than one parameter that significantly affects prediction performance depending on different values. The objective of this study is to propose a parameter selection technique to enhance the performance of CPDP. Using a Harmony Search algorithm (HS), our approach tunes parameters of cost-sensitive boosting, a method to tackle class imbalance causing the difficulty of prediction. According to distributional characteristics, parameter ranges and constraint rules between parameters are defined and applied to HS. The proposed approach is compared with three CPDP methods and a Within-Project Defect Prediction (WPDP) method over fifteen target projects. The experimental results indicate that the proposed model outperforms the other CPDP methods in the context of class imbalance. Unlike the previous researches showing high probability of false alarm or low probability of detection, our approach provides acceptable high PD and low PF while providing high overall performance. It also provides similar performance compared with WPDP.
