ASEE 2011 Conference  Development and Implementation of Challenge-Based Instruction in Engineering Graphics Greg Potter, Seokyoung Ahn, Stephen Crown and Robert Freeman Department of Mechanical Engineering The University of Texas – Pan American, Edinburg, TX, USA AbstractThe focus of this paper is to discuss the challenge-based instructional (CBI) materials currentlybeing developed for the Engineering Graphics course at the University of Texas- Pan American.This endeavor concentrates on student retention of the materials being studied, as well as thestudents’ ability to practically apply their new skills. Minority science, technology, engineering,and math (STEM) students have been found, in recent studies, to depart from STEMundergraduate fields to some extent because of the lack of real world connections to the subjectmatter being taught in the classroom. Also, the traditional way of teaching theory first and thenassigning a task may actually stifle creative thought and innovation required in later STEMcourses. Using a CBI approach, the target lessons will be, in effect, taught backwards. In otherwords, the students are presented with a challenge, and then, only when they have had the chanceto think about the problem, the supporting theory is revealed. Our use of CBI is based on theHow People Learn (HPL) framework for effective learning environments and is realized andanchored by the STAR Legacy Cycle, as developed by the VaNTH NSF ERC for BioengineeringEducational Technologies. The materials developed during the course of this study are acollaboration between students and faculty members at the University of Texas-Pan American(UTPA) and South Texas College (STC), a two year Hispanic Serving Institution (HSI).
