기술적 문제 해결을 위한 사고 과정의 분석 : 발성 사고를 통한 상호 문제 해결을 적용한 사례 연구

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze thinking process for technological problem solving. `Thinking aloud pair problem solving (TAPPS)` was applied to observe the thinking process effectively. Problem solving process was videotaped to collect data and protocol was composed. Then data coding was carried out according to the protocol and the frequency and duration were analyzed by two independent observers. The order of frequency of thinking processes was as follow; 1) communicating, 2) constructing models/prototypes, 3) measuring, 4) analyzing, 5) modeling, 6) defining problems, 7) predicting. And the order of duration of thinking processes was as follow; 1) constructing models/prototypes, 2) communicating, 3) designing, 4) measuring, 5) defining problems, 6) experimenting, 7) modeling. Thinking processes like context, customer analysis, technology review, and values were not observed. Inter coder reliability were 0.86 & 0.87 and intra coder reliability were 0.94 & 0.97 in the frequency and duration analysis by two independent observers.
