. The models were graded by three experts in the field using a rubric which focused onthree key aspects of the model project. Those aspects included craftsmanship, design quality, andscale (proportion). The measures of craftsmanship and scale produced a large effect ( d = .82; d= .86) with significant probability values (p < .047; p < .043), while the measure of designproduced a small effect size ( d = .22) with a non-significant probability value ( p < .536) whencomparing the rapid prototyped models to the traditionally built models.Introduction Creating physical models or prototypes has traditionally been a part of engineering andthe design process. These models serve several purposes, including providing a demonstrativeform

effectiveness of their teaching. Finally, a learning environment mustbe community-centered, one in which students are provided opportunities to learncollaboratively.There are many efforts underway within STEM education to move away from traditional lecturemethods of delivery towards more novel methods designed to engage the students in the learningprocess.9-12 In many cases, these methods are taking the How People Learn concepts fromtheory to practice. The highlights of two specific programs, Project Galileo11 and VaNTH12follow.Project Galileo has developed two novel pedagogical approaches: Peer Instruction and Just-in-Time Teaching. These approaches are designed to provide students “with greater opportunity forsynthesizing concepts while instructors
