The purpose of this study is to correlation analysis between technological problem-solving traits and engineering design competency. To this end, correlation analysis and regression analysis between technological problem-solving traits and engineering design competency were used to analyze the relationship between each other. To collect data on individual characteristics, technological problem-solving traits, and engineering design competency, a survey was conducted with university students. As a result of the analysis, there was no difference in engineering design competency by gender, but there was a difference in technological problem-solving traits. There was no difference in technological problem-solving traits by major, but there was a difference in engineering design competency. As a result of correlation analysis, the correlation was found. In the case of regression analysis, a statistically significant result was found in the problem-solving trait domain, and the regression analysis model was found to be suitable. The results of the analysis of differences in engineering design competency according to technological problem-solving traits showed that the effective problem solvers were significantly higher.

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.

Efficient evidential reasoning is an important issue in the development of advanced knowledge based systems. Efficiency is closely related to the design of problems solving methods adopted in the system. The explicit modeling of problem-solving structures is suggested for efficient and effective reasoning. It is pointed out that the problem-solving method framework is often too coarse-grained and too abstract to specify the detailed design and implementation of a reasoning system. Therefore, as a key step in developing a new reasoning scheme based on properties of the problem, the problem-solving method framework is expanded by introducing finer grained problem-solving primitives and defining an overall control structure in terms of these primitives. Once the individual components of the control structure are defined in terms of problem solving primitives, the overall control algorithm for the reasoning system can be represented in terms of a finite state diagram.

An impetus for reviving research in mathematical problem solving is the recent advance in methodological thinking, namely, the design experiment ([Gorard, S. (2004). Combining methods in educational research. Maidenhead, England: Open University Press.]; [Schoenfeld, A. H. (2009). Bridging the cultures of educational research and design. Educational Designer. 1(2). http://www.educationaldesigner.orgied/volume1/issue21]). This methodological approach supports a "re-design" of contextual elements to fulfil the overarching objective of making mathematical problem solving available to all students of mathematics. In problem solving, components critical to successful design in one setting that may be adapted to suit another setting include curriculum design, assessment strategy, teacher capacity, and instructional resources. In this paper, we describe the implementation, over three years, of a problem solving module into the main mathematics curriculum of an Integrated Programme school in Singapore which had sufficient autonomy to tailor-fit curriculum to their students.

컴퓨팅 사고력은 컴퓨터를 기반으로 하는 문제해결에 관한 하나의 사고 과정으로 정의될 수 있기 때문에 일반적인 문제해결의 과정에서 관련된 컴퓨팅 사고력 개념들을 살펴보는 것은 컴퓨팅 사고력을 이해하는데 도움이 될 수 있다. 이를 위해 본 연구에서는 관련 연구를 통해 컴퓨팅 사고력의 핵심 요소들을 뽑아내고 그러한 요소들이 문제 해결과정에서 어떻게 사용되는지를 기술한다. 또한 문제해결과정에서의 컴퓨팅 사고력 요소들을 인지적인 측면에서 살펴본 후, 각 단계에서의 학습활동과 학습평가 요소들을 기술한다. 이를 기초로 문제 해결의 관점에서 컴퓨팅 사고력을 위한 기본 수업 프레임워크를 제안한다.

This study aimed to identify the causal relationships among self-regulated learning strategy, problem solving efficacy, task value and learning outcome, and mediation effect of self-regulated learning strategy in engineering capstone design course. The data were collected from 363 university students who enrolled in capstone design courses and analyzed using structural equation modeling method. The results were: first, problem-solving efficacy and task value exerted significant effects on self-regulated learning strategy. Second, self-regulated learning strategy exerted significant effects on learning outcome, but problem-solving efficacy and task value did not. Third, problem-solving efficacy and task value showed significant indirect effects on learning outcome, which confirmed that self-regulated learning strategy fully mediated between two exogenous variables and learning outcome.

This study aimed to enhance creative problem solving skill by using the Creative Problem Solving (CPS) learning model which was developed based on creative problem solving approach and five essential features of inquiry. The key strategy of the CPS learning model is using real life problem situations to provide students opportunities to practice creative problem solving skill through 5 learning steps: engaging, problem exploring, solutions creating, plan executing, and concepts examining. The science content used for examining the CPS learning model was "matter and properties of matter" that consists of 3 learning units: Matter, Solution, and Acid-Base Solution. The process to assess the effectiveness of the learning model used the experimental design of the Pretest-Posttest Control-Group Design. Seventh grade-students in the experimental group learned by the CPS learning model. At the same time, students at the same grade level in the control group learned by conventional learning model. The learning models and students' prior knowledge levels were served as the independent variables. The creative problem solving skill was classified in to 4 aspects in: fluency, flexibility, originality, and reasoning. The results indicated that in all aspects, the students' mean scores of creative problem solving between students in experimental group and control group were significantly different at the .05 level. Also, the progression of students' creative problem solving skills was found highly progressed at the later instructional periods. When comparing the creative problem solving scores between groups of students with different levels of prior knowledge, the differences of their creative problem solving scores were founded at .05 level. The findings of this study confirmed that the CPS learning model is effective in enhancing the students' creative problem solving skill.

본 논문에서는 중학생으로 대상으로 디자인 씽킹 기반 인공지능 교육 프로그램을 개발하고 이를 적용하여 창의적 문제해결력에 미치는 영향을 검증하였다. 검사도구는 이화선, 표정민, 최인수(2014)의 CPS 이론을 토대로 창의적 사고유형 능력을 측정하기 위한 검사도구인 창의적 문제해결 프로파일 검사(CPSPI: Creative Problem Solving Profile Inventory)를 사용하였다. CPSPI는 기존 검사들의 한계를 보완하여 인지적 선호도와 인지적 능력을 평가하고, 자신의 아이디어를 타인과 공유하고 설득하는 단계를 포함하였다. 디자인 씽킹 기반 인공지능 교육 프로그램 적용 전 후, 창의적 문제해결력을 분석한 결과, 모든 영역에서 유의미하게 상승하였다. 중학생의 창의적 문제해결력을 분석한 결과 문제발견 및 분석, 아이디어 생성, 실행계획, 실행, 설득 및 소통 영역에서 유의미한 결과가 나타났다. 인공지능교육에서 창의적 문제해결력을 향상시키기 위한 교수학습 방법으로 디자인 씽킹의 효과를 확인하였다.
