Although the acquisition of information may be done individually, knowledge is created from the social context of peers, teachers. And feedback on the appropriateness and effectiveness of their knowledge and skill is commonly received. Learning occures effectively within environment that have shared understanding of problems and various tools to solve problems. The purpose of this study is to apply the main principles of creative Problem solving and develop e-PBL(Problem-Based Learning) to enhance creative problem solving skill. In this research, the group of students who studied by means of e-PBL based on web 2.0 showed much more satisfaction and problem solving skill than the other group of students who did by e-Learning.

In this study, we conducted classroom activities that are exploring and explaining visualized materials for problem solving of school mathematics with pre-service teachers in 2007~2009. After finishing these classroom activities, pre-service teachers recorded an afternote that includes changes of their thinking about mathematics and mathematics education through these activities in this study. We collected various opinions of pre-service mathematics teachers. From the analysis these data, we searched educational effects of our classroom activities. Through conducting the practice like these classroom activities of our study, pre-service mathematics teachers will have an opportunity of a practical training that supports the teaching of mathematical problem-solving. Moreover their PCK will be enhanced. Also, They will learn a good way to realize the aim of school mathematics curriculum.

Problem solving and mathematical applications have been increasingly emphasized in school mathematics over the past ten years. Recently it is recommended that mathematical applications and modeling situations be incorporated into the secondary school curriculum. Many researches on this approach have been conducted in Korea. But unfortunately two thirds of these researches have been studied by graduate students. Therefore, more professional researchers should be concerned with the study related to mathematical modelling activity. This study is planning to investigate and establish i) the concepts and meanings of mathematical model, mathematical modelling, and mathematical modelling process, ii) the properties of problem situations introduced and dealt with in mathematical modelling activity, and iii) relationship between mathematical modelling activity and problem solving activity, and so on. To accomplish this, this study is based on the analysis and comparison of 11 articles published in domestic journals and 22 domestic master papers.

It is important to improve the creative problem- solving ability through subject matter education. Especially, Informatics education is important to improve the problem-solving ability by using computer as well as the general problem-solving ability. This paper identifies the creative problem- solving ability which is required in Informatics education. The cognitive components of the creative problem-solving ability are organized as the result of crossing the problem-solving ability and the creativity. This paper investigated the validity of the contents as judged by a panel of experts. The cognitive components of creativity are the elaboration, sensitivity, and reorganization in the step of 'Understanding and Analysis the Problem'. Also, The cognitive components of creativity are the fluency, flexibility, and originality in the step of the 'Exploring the Problem Solutions'. The cognitive components of creativity are elaboration in the step of the 'Design the Problem Solution' and 'Implementation'. Finally, the cognitive components of creativity are the flexibility and elaboration in the step of the 'Evaluation'.

The purpose of this study was to analyze the effectiveness of Capstone Design Program on creative leadership, problem solving ability and critical thinking of nursing students. The subjects of 18 experiment groups taking course in nursing capstone design of U university in P city and 20 control group of K university in G city. Data were collected before and after nursing capstone design class using self-reported questionnaire. Students Creative leadership and problem solving ability showed significant showed improvements after the Capstone Design Program. Creative leadership, Problem solving ability and critical thinking was positively correlated and then Problem solving abilities appeared to be higher improved critical thinking. Therefore, it is recommended that sufficient repetitive practice is to be made in order to improve Creative Leadership, Problem solving ability and critical thinking.

The purpose of this study was to identify the effect of problem solving ability and critical thinking disposition on communication competency of nursing students. The subjects of this study were 289 students at two universities located in C and G province. The collected data were analyzed by multiple regression analysis. The results showed that communication competency of nursing students was positively correlated with problem solving ability and critical thinking disposition. Communication competency was explained 40.6% of the variance in critical thinking and problem solving ability. Therefore, in order to improve the communication competency of nursing students, it is necessary to develop an educational program that improves critical thinking disposition and problem solving ability.

The purpose of the study was to compare the effects of two instructional methods, which were the instructor-led instruction and the simulation delivery instruction on students' well-structured and ill-structured problem solving performance and motivation. 29 undergraduate students participated in the study and repeated measure design was used. We found significant difference of means in ill-structured problem solving performance and only relevance scale in motivation.

This paper is about the hardness of the Election problem in asynchronous distributed systems in which processes can crash but links are reliable. The hardness of the problem is defined with respect to the difficulty to solve it despite failures. It is shown that problems encountered in the system are classified as three classes of problems: F (fault-tolerant), NF (Not fault-tolerant) and NFC(NF-completeness). Among those, the class NFC is the hardest problems to solve. In this paper, we prove that the Election problem is the most difficult problem which belongs to the class NFC.

Many current researches are limited in the statistics field, which is a part of mathematics class in the secondary school. Moreover, it's hard to apply to the elementary school since they are written in English. To overcome this limitations, the objectives from the unit that is suitable for using EXCEL in the elementary mathematics lessons are selected in this research. And a problem-based learning model for these lessons would be introduced that it can help students to focus on solving substances of the problems by reducing the time for arithmetic calculation.

This paper introduces a model of practice education for creative problem solving, using five steps on CPS. Learners can get the motivation about development of creative thinking and problem solving skill through the theory of CPS. Furthermore, they can apply problem solving skill to various problem. As a result of the study, the learners could realize the importance of the problem definition and the creative problem solving method. We proposed a guideline about five steps of CPS method and a method about idea evaluation. So, we established the education model about leaners can get the creative problem-solving skill more efficiently.
