The purpose of this study was to design the coaching strategies for the problem based learning and examine 'the problem situation' to analyze the process of learning as it applies to the students' perception on problem based learning. The steps of this model were as follows: 1) presentation of the problem situation 2) confrontation of the problem 3) know/ need to know 4) definition of the problem statement 5) collection and sharing of information 6)generation of possible solutions 7) assessment of the best fit of solutions 8) presentation of the solution. Problem-based learning steps and coaching strategies were designed and implemented to 2nd grade high school students for the environment teaching unit. The results demonstrated that group discussion in the know/need to know step was most helpful for students to review what they know and generate solutions. At first students tend to state problems widely but through repeated group discussions they gradually clarified the problems. In the students' personal reflection notes and perception questionnaire of problem-based learning, many students especially showed difficulties in defining the problem statement. In contrast they participated actively in the learning process and express their opinions enthusiastically. Therefore, this study suggests that developing problem situation based on real context is of great importance for implementing a problem based teaming model continuously.

The purpose of this study is to investigate the evaluation scores among various evaluators such as tutor, peer, and self evaluation, the lenience and central tendency among these various evaluators, and the correlation between evaluation scores among the various evaluators and the paper test score in the Problem-Based Learning (PBL). For the research, tutor, peer, and self evaluations were carried out with PBL effectiveness evaluation tool for the 105 nursing students taking classes using PBL, and paper test was conducted after the PBL class ended. The collected data were analyzed by SPSS WIN (V. 12.0). The study results showed that peer and self evaluation scores were higher than tutor evaluation score. Also lenience and central tendency were higher and stronger in peer and self evaluation than in tutor evaluation. Paper test score had a significant correlation with tutor evaluation score, but not with peer or self evaluation scores.

The purpose of this study was to verify that the practical skill instruction of the heat treatment and the tensile strength test using the problem-based learning is more effective than the traditional skill instruction in improving the key competencies. For the study, various literature researches were reviewed intensively about problem solving process, problem -based learning, and learning principals. The process of the practical skill instruction using the problem-based learning was composed with planning, executing, testing and evaluating. Based upon the conclusion of this study, the practical skill instruction using the problem-based learning was more effective than the traditional practical skill instruction of the heat treatment and the tensile strength test in improving the key competencies.

In this research, we proposed a learner tailoring question recommendation system for web based learning evaluation system. For teaming evaluation process, this system used the item difficulty Each question was stored and managed to the question bank. Item difficulty was recalculated during teaming process and feedback in next course. For learner tailoring question recommendation, learner could choice the teaming part and set the learning difficulty. In application result of proposal method, almost learner could improve learning score by controling teaming difficulty.

In this paper, 1 design a mode of educational contents for Problem Based Learning(PBL) fitted education using ICT. I design a teaching and loaming schedule for PBL using ICT. I search pertinent items of educational contents to provide to student in PBL and design a mood fitted them. ,also, 1 design a pertinent mode of system to carry out a teaching and teaming schedule. Therefor, a teaching and learning schedule designed in this paper will apply easily. Because PBL manages ill-structured problem reflected the actuality and is high ratio which student participate in instruction, 1 expect that we take the effect of instruction using ICT in PBL.

This thesis focuses on developing the appropriate model for teaching Internet ethics based on problem-based learning. In the new learning model, participation of students such as discussion and writing methods is considered important. The research applied the new method at class and analyzed the change in Internet ethics. The result of research shows that internet ethics of learner improved in the voluntariness, respect, participation, responsibility area. Especially, the voluntariness and responsibility areas showed statistically meaningful improvement.

Educating qualified elementary school teachers depends on excellent pre-service education. The high quality of education is accomplished by various interactions between teachers and learners, as well as active participation by students. In the present study, online problem-based learning and an e-portfolio were used to examine the effect on the computer-curriculum education to reflect social and individual needs, and to enhance the quality of instruction at universities. Students (n=105) participated in six different problem-based learning sessions. At the same time, they developed Blog e-portfolios as individual and group products, and wrote reflective journals that focused on their learning processes and results. A qualitative analysis method was employed to analyze the reflective journals. The results of the analyses showed the following: 1) Increasing the understanding of the computer-curriculum education, 2) enhancing students' competence in using ICT potentially, 3) cultivating student-centered teaching and learning strategies on ICT, and 4) enhancing competence of future teaching activities through experiencing e-portfolio as a performance-assessment tool.

This study aims to develop and apply problem Based learning classes through skin beauty basics and practical classes to foster experts close to the beauty care field. Students are presented with a problem to solve in practice in the field of skin care, and in order to solve the problem, intellectuals try to come up with a solution to solve the problem jointly. Conduct skin beauty learning classes that apply problem-based learning to students, and analyze the effects after taking the classes. As a result of this study, by presenting actual problems in the field, scientists were able to actually do what experts do, and it was possible to come up with various solutions to a given problem in the future, and to share parts to expect problem-solving abilities. These results suggest that problem-solving and the problem-centered learning process for problem-solving have a positive effect on improving his problem-solving ability.

Problem-Based Learning(PBL) is one of constructionism's model which is learner-centered learning. In this paper, a role-play base PBL using character is proposed to study importance of information security. It is different from the other PBL models in that it reflects the characteristics of learners, learning task. And it is learning support system which the learners preside their own learning activities using Internet and mobile devices. By experimental result showed that proposed method was more effective than traditional teacher-oriented teaching method about information security in self-directed learning, cooperative learning, contents-making and attraction.
