Computer-aided design (CAD) simulation environments offer opportunities for students to evaluate, redesign, and visualize engineering design solutions quickly and get feedback. However, the use of CAD simulation tools in precollege settings is relatively rare. This study explores design strategies used by experienced designers in Energy3D, a CAD simulation environment designed for learning settings, to provide insight into supporting students' use of CAD simulation environments in precollege settings. Five designers engaged in a think-aloud of a design challenge used with precollege students. Video and log data were collected and analyzed. Emergent themes that emerged across designers included problem definition, problem decomposition, and systematic but not tightly controlled exploration. We discuss the implications for designing instruction with CAD simulations in precollege settings.

在 CAD 学习环境中探索经验丰富的设计师的策略

计算机辅助设计 (CAD) 仿真环境为学生提供了快速评估、重新设计和可视化工程设计解决方案并获得反馈的机会。然而，在大学预科环境中使用 CAD 模拟工具相对较少。本研究探讨了经验丰富的设计师在 Energy3D（一种专为学习环境而设计的 CAD 模拟环境）中使用的设计策略，以深入了解支持学生在大学预科环境中使用 CAD 模拟环境。五位设计师参与了与大学预科学生一起使用的设计挑战的思考。视频和日志数据被收集和分析。设计师之间出现的新主题包括问题定义、问题分解和系统但不受严格控制的探索。
