研究了工科专家、工科大四学生和工科大一学生在使用问题分解和问题重组时的差异。参与者以双人组的形式在1小时内完成一项工程设计挑战。整个设计过程都被视频和音频记录下来。设计会议结束后，成员们参加了一个小组面试。视频和音频数据被转录，分割，并编码进行比较。结果显示，工程专家，大四学生和大一学生之间的差异，在设计思维。在工程设计中，学生倾向于使用深度优先分解，专家倾向于使用广度优先分解。结果还表明，学生在问题定义阶段花费的认知努力比工程专家少。
The authors investigated the differences in using problem decomposition and problem recomposition between dyads of engineering experts, engineering seniors, and engineering freshmen. Participants worked in dyads to complete an engineering design challenge within 1 hour. The entire design process was video and audio recorded. After the design session, members participated in a group interview. Video and audio data were transcribed, segmented, and coded to make comparisons. Results show differences between engineering experts, seniors, and freshman in design thinking. Students tend to use depth-first decomposition, and experts tend to use breadth-first decomposition in engineering design. The results also show that students spend less cognitive effort on the problem-definition stage than engineering experts.
