The focus of this study was to investigate whether flow occurs during both goal-directed and experiential activities, if experiential and foal-directed flow states differ in terms of various measures and dimensions. Fifty male and eighteen female subjects were participated in controlled, comparative experiment between goal-directed and experiential activities in problem-solving tasks. The findings indicate that subjects experience more curiosity and involvement(focus) in problem solving tasks with experiential activities. However, the results showed subjects experience more enjoyment in tasks with goal-directed activities. Findings of this study suggested that more sophisticated and quantitative measures in various dimensions should be constructed and verified in order to apply flow theory to human-computer interaction.

The purpose of this study is to investigate the features of elementary students' intuitive thinking emerged during problem solving activities as it related to thermal phenomena, focusing on when intuitive thinking appears and how it is related to logical thinking. For this, we presented a problem related to thermal phenomena to nine 5th-grade students, and examined how students' thinking emerged in the activities. We conducted clinical interviews to investigate the thinking process of students. The results of this study are as follows. First, students made their own solutions and justified it later during the emergence process of intuitive thinking. It was also found that students connected concrete materials and abstract concepts intuitively. They solved the problem by making predictions even when information is insufficient. Second, it was shown that intuitive thinking can emerge through the intended strategies such as drawing a mental image, thinking from a different perspective, and integrating methods. These results, which are related to the students' intuitive thinking has received little attention and will be the basis for helping students in the context of discovery of their problem solving activities.

With the introduction of the 2015 revised curriculum, software education became mandatory in elementary school. The practical subject in the content for the software education consists of information ethics, algorithms, programming, and computer science. Especially, elementary school encourages the unplugged activities. Unplugged activities are preferred among the teachers in the education field as a teaching-learning method. However, those teachers pointed out that the lack of suitable unplugged activity materials was the biggest challenge. In addition, it was pointed out that the existing materials were not suitable for achievement standards, and there are many simple playing-oriented educations that are not linked to computing activities. In this study, we developed an unplugged activity-oriented robot that can be used for the elementary students to learn the basic control structure suggested in the achievement criteria SW education and to develop creative problem solving ability through various activities using sensors. The effectiveness was verified through the software class using the developed robot in this study.

The purpose of this study is to examine a theoretical framework for the interactions of learning in a small group setting of mathematical problem solving. Many researchers already have described the theoretical background for the small group settings in problem solving. However, most of the literatures merely have reported findings of achievement and rising of test scores. They ignored the observation of process taken during the small group work and have not determined how various psychological, social and academic effects are created. As results of the study, two types, mutual collaboration and asymmetric collaboration, of interactions are observed as the interactions of learning, which are conceived as the cores of authentic mathematical activities.

In mathematical modeling tasks, where students are exposed to model-eliciting for real and open problems, students are supposed to formulate and use a variety of mathematical skills and tools at hand to achieve feasible and meaningful solutions using appropriate problem solving strategies. In contrast to problem solving activities in conventional math classes, math modeling tasks call for varieties of mathematical ability including mathematical creativity. Mathematical creativity encompasses complex and compound traits. Many researchers suggest the exhaustive list of criterions of mathematical creativity. With regard to the research considering the possibility of enhancing creativity via math modeling instruction, a quantitative scheme to scale and calibrate the creativity was investigated and the assessment of math modeling activity was suggested for practical purposes.

This article aims to analyze the experience of designing and operating a class model linking undergraduate and graduate students in engineering education and suggest its development direction. To achieve these objectives, the undergraduate-graduate linked class model was applied to community problem-solving education and a case was analyzed. It also specifically presented the process of how we design the class model and what the actual operational performances and improvements are. This study found that undergraduate and graduate students could build integrated and horizontal cooperative relationships in their classes through undergraduate-graduate linked education and, particularly, graduate students could gain meaningful educational experiences. However, it was difficult to obtain tangible performances through the team activities of these students within a semester. In order for engineering colleges to operate undergraduate-graduate linked education, it would be necessary to provide a longer and more systematic educational environment and better curriculum. The study tried to seek specific tasks and ways to improve them.

This study examines the social problem-solving R&D policies from the perspective of 'Mission-oriented innovation policy'. To this end, we analyzed the 'second science and technology-based social problem solving plan' in terms of civil society's participation, securing the government's dynamic capabilities, and government's risk investments. The plan introduces an institutional framework for civic participation for social problem-solving innovation, strengthening R&D program coordination and integration, and new innovation ecosystem formation. However, there is a need for a concrete program to overcome a path dependency of existing activities. Otherwise new institutions are likely to be formalized. In addition, in order to derive risk investment, it is necessary to integrate innovation policy with social policy fields such as community care and climate change. It is necessary to establish an policy process that combines the agenda of social policy beyond with R & D policy, and to forms a platform for problem solving, integrates various technologies, industries and resources.

The purpose is to figure out the effects of education for environmental pollution prevention through forest experiences on children's nature-friendly attitudes and scientific problem solving ability. To achieve this, an experiment was conducted on total 44 kindergarten children in a class for 5-year-olds, who are classified into experimental group of 22 children(12 male children, 10 female children) and comparative group of 22 children(13 male children, 9 female children), in a C farming village. The results are as follows. First, the change of children's nature-friendly attitudes by group showed that education for environmental pollution prevention through forest experiences had an effect on the improvement of children's nature-friendly attitudes. Second, the change of children's scientific problem solving ability by group showed that education for environmental pollution prevention through forest experiences had an effect on the improvement of children's scientific problem solving ability. This implies that children's forest activities are useful in improving their nature-friendly attitudes and scientific problem solving ability.
