This paper investigates iteration and fixation in design by mining digital footprints left by designers. High school students used computer-aided design software to create buildings in an urban area, with the goal of applying passive solar design techniques to ensure optimal solar gains of the buildings throughout a year. Students were required to…

The ease with which 3D CAD models may be modified and reused are two key aspects that improve the design-intent variable and that can significantly shorten the development timelines of a product. A set of rules are gathered from various authors that take different 3D modelling strategies into account. These rules are then applied to CAD…

The design of this study was a multiple case study conducted to examine the knowledge, pedagogical principles, and challenges involved in providing engineering-oriented professional development for teachers at the secondary school level. A set of criteria was used to identify five representative projects for analysis in the US. A variety of tools…
