“…In grades K‐12, engineering design is introduced as the core of engineering practice, with design in this context referring to a systematic and iterative decision‐making process (Brophy, Klein, Portsmore, & Rogers, ; Dym, Agogino, Eris, Frey, & Leifer, ; Guzey, Tank, Wang, Roehrig, & Moore, ; Guzey et al, ; Moore, Johnson, Peters‐Burton, & Guzey, ; NAE, ; NRC, ). For example, in a design‐based science unit, students design vehicles following an iterative design process in which they first develop a prototype (e.g., a modestly working vehicle), experiment with the variables to discover ways to design an improved prototype (e.g., forces acting on the car), and redesign (e.g., a car that travels farther) (Guzey et al, ).…”
