The purpose of this study was to develop a test tool for convergence problem solving skill. To this end, constructs of convergence problem solving skill were defined in three domains: convergence attributes, convergence thinking, and convergence literacy domains. Thirty-seven pilot items were developed on the basis of the sub-categories for each domain that was defined through intensive literature review; problem solving & convergent thinking and creative thinking for convergence thinking domain, individual and social propensity for the convergence attributes domain, and convergence literacy as convergence literacy domain. Through an exploratory factor analysis, 30 items in the constructs of the test tool were confirmed. A confirmatory factor analysis result showed that the five construct models well captured the covariance between all the items well. Finally a statistical result shows that the reliability of the items and constructs were well established (Cronbach's α value= .963). Thus, the test tool for convergence problem solving skill developed in this study was statistically reliable.

Objectives: The purpose of the study was to investigate the correlation between critical thinking and problem-solving abilities in dental hygiene students. Methods: This is a cross-sectional study. A self-reported questionnaire was completed by 386 dental hygiene students enrolled in Gwangju Health university from August 30, 2017 to September 2, 2017. The general characteristics of the subjects, their critical thinking and problem-solving abilities were measured for the study. The tool to measure critical thinking was adapted from Yoon which had a Cronbach' alpha of 0.77. The tool for problem-solving ability was adapted from that used in Heppner & Petersen, which had a Cronbach' alpha of 0.77. The collected data are analyzed using ANOVA, Pearson's Correlation analysis, and multiple regression using SPSS/Win 18.0 program. Results: The results show that critical thinking scored 3.45 while problem solving ability scored 3.20. The correlation between critical thinking and problem-solving abilities was found to be strong. The strongest positive correlation in problem-solving ability was critical thinking (p<0.001). The multiple regression analysis suggests that the factors affecting problem solving ability of the subjects was statistically significant. The significant variables included critical thinking (${\beta}=0.440$) (p<0.001), satisfaction with one's major (${\beta}=0.108$) (p<0.05), interpersonal relationships (${\beta}=0.104$) (p<0.05) and academic performance (${\beta}=0.086$) (p<0.05) with an explanatory power of 38.3%. Conclusions: It is necessary to develop a curriculum and learning method for critical thinking and problem-solving abilities in the dental hygiene students.

Many methods have been suggested for a creative problem solving approach. TRIZ approach is ranked top in its practical application because it is originated from the real patent analysis. This approach is assumed to be generic which can be applied to any types of problems regardless of problem type and its domain. The objective of this study is to propose a creative problem solving approach using TRIZ's contradiction analysis, then introduce a case study of applying this approach to a creative design coursework. Main topic covers a creative problem solving approach, a problem definition using TRIZ contradiction analysis, finding invention principles, and problem solving from the generic approach. For the course project, Roborobo tool is adopted to implement the design concept. This coursework helps students finding a general problem solving approach, and applying a generic solution for their specific problem domain.

QFD(Quality Function Deployment) is a very important tool to improve market share by reducing the gap between the voice of customer and the product's performance. But QFD is not a problem solving tool, although it is very useful in identifying what has to be solved or improved in order to meet the customer's desires. TRIZ has proved to be a very strong tool to solve the difficult problems that requires inventive thinking. QFD integrated with TRIZ becomes hot research recently. But merely linking between HOQ(House of Quality) in QFD and the contradiction matrix in TRIZ can not provide designers with a concrete method to solve the technical problem in the design process. Practically, the contradiction matrix and 40 inventive principles are not helpful for solving the technical problem. To solve the technical problem using TRIZ, a search for the tool and the object involved in the problem is made, from which the wanted result should be derived. A practical method to integrate QFD and TRIZ is proposed in this paper.

In this paper, we developed a design thinking-based artificial intelligence education program for middle school students and applied it to verify the impact on creative problem-solving skills. The inspection tool used the Creative Problem Solving Profile Inventory (CPSPI), an inspection tool for measuring creative thinking type ability based on the CPS theory of Hwasun Lee, Jungmin Pyo, Insoo Choe(2014). CPSPI included the steps of evaluating cognitive preferences and cognitive abilities by supplementing the limitations of existing tests, and sharing and persuading one's ideas with others. Before and after applying the design thinking-based artificial intelligence education program, as a result of analyzing the creative problem-solving ability, it increased significantly in all areas. As a result of analyzing the creative problem-solving ability of middle school students, significant results were found in the areas of Problem Detection and Analysis, Idea Generation, Action plan, Execution, Persuasion and Communication. The effect of design thinking was confirmed as a teaching and learning method to improve creative problem-solving ability in artificial intelligence education.
