본 연구는 2015년 교육과정에 명시된 정보교과의 운영방침과 중등학교 소프트웨어 교육 현황을 분석하고, 이에 대한 문제점을 해결 할 수 있는 방안으로 창의적 문제 해결력을 통한 소프트웨어 교육 모형을 제안한다. 창의적 문제 해결력은 확산적 사고와 수렴적 사고를 통해 학생들이 문제 해결에 필요한 사고를 키울 수 있는 모형이다. 이에 본 논문에서는 컴퓨팅 사고력을 가진 창의·융합 인재 육성이라는 소프트웨어의 교육 목표를 달성하기 위해 기존의 CPS모형과 CT의 요소간의 유사점을 확인하고 이를 바탕으로 새로운 CPS-SW 모형을 제안한다. CPS-SW 모형으로 컴퓨팅 사고력과 창의적 문제해결력을 키울 수 있으며, 이를 통해 미래 사회에 필요한 인재육성을 위한 소프트웨어 교육의 발전에 기여하고자 한다. 또한 CPS-SW 모형을 적용할 수 있는 프로그램과 학생들이 창의적 문제해결력을 키울 수 있는 학습에 대한 연구가 필요할 것으로 예상한다.

In the knowledge based society, it is very important to have an ability to solve problem with knowledge and information. In addition, the number of problems that can not be solved only with existing knowledge are increasing. Therefore, we developed an informatics education program that enhances creative problem solving abilities through systematic collection of information. This program designed to enhance both divergent thinking and convergent thinking. The developed program improves the problem solving ability with learner's internal knowledge as well as new information that is collected from external world. More practical and effective program can be provided through continuous program improvement.

The purpose of this study was to introduce the practical model on the enhancement of the divergent and convergent thinking skills through inquiry instruction in science class. In this study, the creative thinking skill has been defined by divergent thinking skill as the narrow sense. In the science field, the problem solving thinking skill is just same as the inquiry thinking skill. Also, the problem solving thinking skill has been defined by convergent thinking skill as the critical thinking skill. This new instruction had been used for the college student in the class of general chemistry laboratory for the one semester. The first results had been founded that the students' divergent thinking skill had been increased significantly. Especially, the skills of recognition of problems, the skills of making hypothesis, and the skills of transformation and interpretation of data had been increased significantly. The second results had been founded that the students' convergent thinking skill had been increased significantly. Especially, the skills of making hypothesis, the skills of transformation and interpretation of data, and the skills of making conclusion and generalization had been increased significantly. The third results had been founded that the students' the creative and problem solving thinking skill had been increased significantly. Especially, the rest of all skills exception the skill of control variables had been increased significantly.

It has been understood that Confucian culture only blocks creative problem solving(CPS). However, it is claimed that Confucian culture exerts positive and negative influence on nurturing CPS. Confucian culture fosters CPS by urging strong motivation for learning, and building rich base of knowledge and skills in general and in specific domains through teaching joy of learning and hardworking fueled by parents' education fever. Confucian culture has negative influence on CPS with emphasis on obedience and conformity. Keju system, as a part of Confucian culture, resulted in excessive private tutoring to prepare for the high-stakes test, delimitation of students' experiences to matters to be tested, and students' weak interest, self-concept, and self-directed learning. Negative influence from Confucian culture on CPS is analyzed and some suggestions are provided for revising educational policies and educational practices in order to maximize the creative problem solving in Confucian countries.

General form of the programing education is finding and realizing algorithm to solve problems faster and more efficiently. In other words, it is based on convergent thinking. However, the programming education must have different characteristics to education targets. For elementary school students, it is needed to provide various experience-centered investigation environments. They should learn how to find the most efficient problem solving method by themselves. This study had adopted divergent thinking strategy where divergent thinking and convergent thinking can be repeated at the same time to suit a programming education with great importance of convergent thinking to elementary school leaners, and analyzed its effects. This study was applied to 5th graders, and 12 times of experimental measure classes were conducted by dividing them into the control group that conducted general programming class and the experimental group that conducted a programming class including divergent thinking of CPS model. As a result, CPS model had significant effect on the subordinate elements of creative problem solving skills, self-assurance, independence, and divergent thinking.

This study examined the relation between the quality of constructive play and convergent and divergent problem solving. The subjects were 48 five-year-old children. Unit blocks were used to test the quality level of constructive play; a 40 piece puzzle and pattern blocks were used to test convergent problem solving; the pattern blocks also were used to test divergent problem solving. Children's block play was videotaped and pictures were taken of constructions made by children. Data were analyzed by correlation and stepwise multiple regression. Results showed statistically significant correlations between the quality of constructive play and convergent and divergent problem solving. Among the sub variables of constructive play, social play patterns affected convergent problem solving; diversity affected divergent problem solving.

The purpose of this study was to develop teaching materials using Pyramid model of divergent thinking, Inverse pyramid model of convergent thinking and Diamond model of divergent-convergent thinking. And the teaching materials was implemented to 120 students in middle school over 10 weeks. Results indicated that the experimental group presented statistically meaningful improvement in creative thinking skills, especially in fluency and flexibility(p<.05). Also the teaching materials contributed to improve critical thinking skills, especially in inquiry process of recognizing problems, making conclusion and generalization(p<.05). Moreover, academic achievement was improved(p<.05). But, there was no significant improvement in creative personality(p<.05).

The purpose of this study was to develop problem-solving inquiries for the science gifted and to analyze the effects of problem-solving inquiries. The problem-solving inquiries were composed of scientific knowledge, scientific inquiry skills and creative thinking. The problem-solving inquiries were applied to the science gifted attending the institute of the gifted education. The test of science-creative problem solving (TSCPS) was used to know effects of improvement of science-creativity and the result of TSCPS showed the improvement of science creativity. The analysis of student-student dialogues during experiments showed that the type of dialogue was different on the type of problem-solving inquiry. The dialogue of convergent thinking was frequently showed up on the problem-solving inquiry needed logical thinking whereas that of divergent thinking on the problem-solving inquiry needed idea generation. The problem-solving inquiries had a positive effects on the improvement of the science-creativity.

This study is to analyze the effects of geography class using taboo games on developing student's ability to think. After playing taboo games in which students explain keyword without using presented taboo words, worksheets of participants were analyzed with interviews to demonstrate what kind of thinking skills are working. The results of the analyses are as follows. First, while divergent thinking is applied to students who explain keyword in taboo games, convergent thinking is applied to students who listen to and guess them. Second, as groups play a role as explainer or answerer in turn, they can learn divergent and convergent thinking together. Third, students seem to improve high-order thinking ability like decision-making, critical thinking, metacogniton through taboo games. Fourth, students have a tendency to use a variety of direct and/or indirect experiences (especially, from media) as well as cross curricular knowledge in order to explain keyword without using taboo words.
