Since 2001, we have taught computer in elementary school to become the advanced country of IT in the 21C. However, it is criticized that the contents of information literacy curriculum are weak because they are not the computer science but mainly the computer skills. In 2005, "ICT Education Guide Revision" is published. Thereafter, the curriculum has systematic frame because of the addition of the contents of computer science. However, the curriculum for improving the ability of problem solving which is one of the abilities of human in the information society is somewhat defective. Therefore, in this paper I analysed the curriculums of problem solving field in elementary school level of some countries and proposed the revised curriculum of problem solving field of elementary computer science course.

With a shift in the rural development process toward a bottom-up approach, the need to enhance the endogenous capacity of communities has become the core of rural development. In this regard, scholars have paid close attention to social capital to identify ways to facilitate endogenous rural development but focused mainly on relationships between social capital and local environment. That is, few studies have investigated the relationships between social capital and its various dimensions in the context of rural development initiatives. This study examines the effects of social capital on the problem-solving ability of community residents'rural development initiatives and assesses the types of social capital associated with such initiatives to propose optimal path for improving this ability. To distinguish between major dimensions of social capital, a questionnaire was developed by considering various stages of the rural development process. The survey considered a sample of 59 employees from public rural development institutions. According to the results, four paths were significant at the 5% level. Among these four paths, three set common goals. The effective channel was the path [common goals${\Rightarrow}$network${\Rightarrow}$cooperation${\Rightarrow}$problem-solving ability]. The key factor in improving problem-solving skills, the endogenous ability of community residents to facilitate rural development initiatives. The results suggest that governments should strengthen education and training programs to help residents set their common goals.

A camp program where the theory of inventive problem solving TRIZ is applied to real problems of the industry was developed and taught at a five-day seminar apart from the standard curriculum at a university D in Gyeonggido. This study focuses on the educational effect that the TRIZ method has on the engineering students when their creative problem solving skills are required to solve industry problems on their own with the knowledge from their courses. For five days, the students were educated about TRIZ and assigned a real industry problem "Removal of friction caused by bubble formation in water heating pipelines". By applying TRIZ to the problem, the students developed an "Air removing Air Arrester" which received the evaluation, "with understanding the system architecture and the task objective causes and formation of the problem could be handled which directly helps the company's R&D". In this case, TRIZ offers the students a guideline and knowledge on how to approach problems and as a result the students provided a practical solution. During the process, the TRIZ method instilled confidence in the students and proved to be a motivation. It becomes obvious that this short-term program has a positive effect on students' way of thinking creatively and increasing their problem-solving abilities.

The purpose of this study was to develop forensic science program for the improvement of scientific creative problem-solving abilities in gifted elementary-school students. A program that consists of six sessions (18 hours) is developed in accordance with the CPS model, which has been already proven effective for the improvement of creative problem-solving abilities. This program was applied to sixth-grade 18 gifted students in an elementary school in Gyeonggi province. Examinations of scientific creative problem-solving abilities were performed before and after applying the program in order to determine its effect on gifted elementary students. A qualitative analysis of students' activity sheets, peer assessment and teacher's class journal was made in order to examine the process of improvement of students' scientific creative problem-solving abilities. The results of this study are as follows: First, forensic science program to enhance the scientific creative problem-solving abilities of gifted students was developed. Second, forensic science program is significantly effective in the improvement of scientific creative problem-solving abilities of gifted children of elementary school (p<.05). Third, in early stage of the class, a student, who showed the highest range of change in pre and post tests, revealed the trend of responding in a short answer type. In the late stage of the class, he revealed the capability of producing various creative ideas promptly. On the other hand, students belonging to the upper group of both pre and post test revealed the improvement of divergent thinking skills such as fluency, flexibility, and originality. Fourth, after class, the students responded that the forensic science program developed in this study intrigued the interests and curiosities, and helped them break away from fixed ideas.

In the near future, as artificial intelligence and computing network technology develop, collaboration with artificial intelligence (AI) will become important. In an AI society, the ability to communicate and collaborate among people is an important element of talent. To do this, it is necessary to understand how artificial intelligence based on computer science works. An algorithmic education focused on problem solving and learning is efficient for computer science education. In this study, the results of an assessment of computational thinking at the beginning of the semester, a satisfaction survey at the end of the semester, and academic performance were compared and analyzed for 28 students who received algorithmic education focused on problem-solving learning. As a result of diagnosing students' computational thinking and problem-solving learning, teaching methods, lecture satisfaction, and other environmental factors, a correlation was found, and regression analysis confirmed that problem-solving learning had an effect on improving lecture satisfaction and computational thinking ability. For algorithmic education, if you pursue a problem-solving learning technique and a way to improve students' satisfaction, it will help students improve their problem-solving skills.

Ill-structured problems have drawn attention in that they can enhance problem-solving skills, which are essential in future societies. The purpose of this study is to analyze and evaluate students' spatial reasoning(Intrinsic-Static, Intrinsic-Dynamic, Extrinsic-Static, and Extrinsic-Dynamic reasoning) and problem solving abilities(understanding problems and exploring strategies, executing plans and reflecting, collaborative problem-solving, mathematical modeling) that appear in ill-structured problem-solving. To solve the research questions, two ill-structured problems based on the geometry domain were created and 11 lessons were given. The results are as follows. First, spatial reasoning ability of sixth-graders was mainly distributed at the mid-upper level. Students solved the extrinsic reasoning activities more easily than the intrinsic reasoning activities. Also, more analytical and higher level of spatial reasoning are shown when students applied functions of other mathematical domains, such as computation and measurement. This shows that geometric learning with high connectivity is valuable. Second, the 'problem-solving ability' was mainly distributed at the median level. A number of errors were found in the strategy exploration and the reflection processes. Also, students exchanged there opinion well, but the decision making was not. There were differences in participation and quality of interaction depending on the face-to-face and web-based environment. Furthermore, mathematical modeling element was generally performed successfully.

This research is a case study of the changes of students's problem solving ability and affective characteristics when we apply to general students MG-CPS model which is creative problem solving model for gifted students. MG-CPS model which was developed by Kim and Lee(2008) is a problem solving model with 7-steps. For this study, we selected 7 first grade students from girl's high school in Seoul. They consisted of three high level students, two middle level students, and two low level students and then we applied MG-CPS model to these 7 students for 5 weeks. From the study results, we found that most students's describing ability in problem understanding and problem solving process were improved. Also we observed that high level students had improvements in overall problem solving ability, middle level students in problem understanding ability and guideline planning ability, and that low level students had improvements in the problem understanding ability. In affective characteristics, there were no significant changes in high and middle level classes but in low level class students showed some progress in all 6 factors of affective characteristics. In particular, we knew that the cause of such positive changes comes from the effects of information collection step and presenting step of MG-CPS model.
