This study intended to explore the instructional effects of e-PBL which means an expansion of availability of PBL using technology. To achieve the goal of this study, a major selective subject was redesigned systematically so that e-PBL activities could be implemented for 4-weeks during the entire semester. Participants' reactions to the e-PBL experience during the experiment period were collected and analyzed. Results of analysis showed that participants could overcome the difficulties and frustrations at an early stage, adapted and assimilated to the e-PBL based instructional environment progressively, and satisfied at the e-PBL activity experiences in overall. They participated in solving the authentic problems with ownership and could solve them effectively and efficiently through frequent communication and collaboration with teammates. Results of this study showed the possibility of instructional innovation of a teacher development institute through e-PBL. Follow-up studies which extend the analyses of the effects of e-PBL based on this study are necessary to additionally verify the effects of e-PBL.

The importance of algorithm education has been emphasized for creative problem-solving capability. Especially, algorithm teaching materials related with mathematics and science are under development to enhance logical thinking. However, there are not enough teaching-learning models applicable in the field of education. Therefore, this paper proposed a teaching-learning model for effective algorithm education. The teaching-learning model reflects two characteristics : an algorithm learning process is spiral, and algorithm education is based on logical thinking. Furthermore, a survey was conducted for students' satisfaction, and the result was a mixed teaching-learning model with PBL, SDL, and peer tutoring. Based on the proposed model, examples of classes for mathematics and science are suggested to show the feasibility of effective algorithm education.

This study is to setup a mathematics PBL model that is right for elementary students. PBL models are developed and applied to actual courses and analyzed. So, a specific plan and practical understanding of PBL mathematics textbooks will be presented. But in order for this to happen, first the mathematics PBL model, that can realize 7th revised curriculum's goal, needs to setup and divided into knowledge, skill and attitude domains. Through this study, the general PBL model and the PBL model appropriate for elementary mathematics was amended and supplemented, this was then applied to courses and analyzed, and the below conclusions were realized. First, mathematical idealization stage is needed for mathematical PBL model. Since an elementary student is shortcoming in problem understanding and mathematical activity, a middle step that allows the student to understand the problem situation mathematizing and find a solution mathematically is desperately needed. Therefore, in this study, we named it the mathematical idealization stage and had it setup. Second, a mathematics information collection stage needs to be prepared for a successful PBL. Through this stage, the students will have an opportunity to gather the necessary information needed and restructure it to solve the problem. Third, the organization stage in mathematical PBL model needs to be strengthened. PBL is not just completed, through the best use of mathematics subject matter to solve the problem. Organization time is needed to allow the students to grow to a more deepened and advanced level. In conclusion, there is significance in providing a specific plan for mathematical PBL model, which can be seen through this study on applying and analyzing elementary mathematics and appropriate PBL models.

This paper explores effectiveness of integrating Problem-Based Learning with Web 2.0 technologies in Computer subject matter education for improving quality of lessons and adapting of social needs for pre-service teachers. Students have studied about computer subject matter for 4 times. The process of leaning have recorded by Web 2.0 tools that is one of the cloud services. Also the students have written reflection journals about experiences of PBL process and results. The PBL process and reflection journals have been analyzed by qualitative data analysis. Conclusions are drawn as to potential for the use of Web 2.0 tools for PBL in computer subject matter. The results of the analyses showed the following: 1) Increasing the understanding of the computer subject matter education, 2) enhancing students' competence in using ICT potentially, 3) cultivating teaching and learning strategies on Web 2.0 environment and 4) enhancing competence of future teaching activities through experiencing e-portfolio as a performance-assessment tool.

현대사회는 지식정보의 사회로서 이러한 사회에서는 지식을 단순히 암기하는 것보다 주어진 지식과 정보를 이용하여 새로운 지적 가치를 창출할 수 있는 자율적이고 창의적인 인재가 필요하다. 창의성 신장의 측면에서 볼 때, 수학은 문제 해결의 다양성, 사고의 유연성을 길러주므로 매우 중요한 과목이다. 하지만 많은 학생들이 수학의 가치와 필요성을 인식하지 못하고 흥미를 잃어가고 있다. 이에 자발적인 학습을 유도할 수 있는 PBL학습을 도입하고자 한다. 그리고 컴퓨터 프로그래밍은 수학 학습에서 학습자의 알고리즘적 사고력을 향상시킨다. 따라서 본 연구자는 수학 흥미도를 향상시키기 위해 스크래치를 활용한 PBL기반의 수학 학습 컨텐츠 개발을 제안한다.

현대사회는 지식정보화 사회이다. 사회는 점점 복잡해지고 개인은 여러 문제를 만나게 된다. 이러한 사회에서는 지식을 단순히 암기하는 능력보다 생활 속에 부딪히는 문제들을 지금까지 배워온 지식과 정보를 활용해서 해결해 나가는 능력이 절실히 요구된다. 기존의 주입식 교육에서 벗어나서 학습자 스스로 필요한 지식을 찾고 적용하는 능력을 키우기 위해 PBL학습을 도입하고자 한다. 그리고 스크래치언어를 활용하여 프로그램을 작성함으로써 초등학생들의 문제에 대한 고찰능력과 사고력을 향상시키고자 한다. 따라서 본 연구에서는 스크래치를 활용한 PBL기반 학습프로그램을 개발하였다.

The education of radiological technology in Korea is provided lots of information but are low effectiveness of studying due to attach importance to traditional lecture preparing for the national exam of radiological technologist. With a critique about traditional education, a new method of teaching, PBL(Problem based learning) can meet with the workplace through problems and see the real world of occupation objectively taking part in a self-directed learning and cooperative discussion process. And when become a radiological technologist as a member of current society can build up solving problems and ability of communicative competence. We suggest problem-based learning for the education of radiological technologist, hope to see make for cultivating radiological technologist of ability and improve the quality of education.

In the 21stcentury, teachers must welcome new technology to ensure the best learning in virtual classrooms, aside from the physical classroom. Google Classroom provides a vital chance to promote blended learning and professional development. The purpose of this study is to specify the procedures in problem design when employing blended problem-based learning (BPBL) and to design problems for learning the contents of the subject. The design of problems is crucial for effective BPBL. The underlying theory of BPBL is that learning is most effectively initiated and facilitated by posing and solving real-life problems that interest the learner, because working on such problems makes learning meaningful and motivates students. Ineffective problem-based learning (PBL) could affect students when acquiring sufficient domain knowledge, activating appropriate prior knowledge, and properly directing their own learning. The procedures for designing good problems are composed of the selection of educational content, figuring out the learner's characteristics, finding problems, setting up roles and situations, and writing down problems. Using these procedures, we designed five integration problems covering the contents of management subjects. Planned management subjects based on BPBL in a Mongolian university focuses on the process of designing problems.

The study analyzed effects of the problem-based learning utilizing cognitive algorithms in elementary mathematics education in terms of academic achievement and math attitude changes. In order to solve the research questions, a cognitive algorithm-based PBL model was derived based on N. Landa's algorithm-based instructional design theory. And the model was applied to a part of second semester math curriculum for 4th grade of an elementary school located in Seoul. The results showed that the PBL utilizing algorithms can be said to have effects on academic achievement. The PBL model is also considered to have positive effects in enhancing mathematical attitudes of the learners.
