Elements of service-learning have beenincorporated across disciplines into traditional classes as well as capstone experiences. Whileproviding significant benefits, challenges also exist in managing relationships with externalclients, finding administrative support for these experiences, and engaging students in moreopen-ended projects.Recognizing these benefits, new capstone projects have been introduced at our mid-sized mid-Atlantic college over the last two

undergraduate students in the fields of engineering and technology requires reflectionand vigilance. In a brief four years the students must grow to understand the principles of theirfield as well as the culture in which they will apply those principles. Given the breadth of topicsstudied in that short time a balance must be struck between the two. The students in the ComputerEngineering Technology (CET) program at Central Connecticut State University (CCSU) studythe principles and the process of engineering design. The work presented here details the balancestruck between the two during the senior capstone classes in that program. A student project isused to examine the output of the process over the course of two semesters in the Fall of 2015

This project is grounded in Butler andCartier’s SRL model, which describes the interplay between affect, motivation, cognition, andmetacognition within academic engineering design activities. Dym & Little’s design processmodel was also used as sensitizing theoretical framework.

China used to be self-sufficient in oil supplies, but isnow estimated to import 40% of its oil consumption.(1) Other industrialized countries such asJapan, Germany, India and Brazil have seen tremendous growth in car sales.The history and projections of oil demand and production support the belief of the theory of peakoil at the present time. Basically, the theory predicts that oil production is at its peak in history,and will soon be below oil demand and possibly create an energy crisis.(1) Economic growth (1)relies heavily on energy supply.
