Most students who enter these programs have very little electronics background or knowledge.
In addition, numerous electrical components are buried deep within the vehicles and hidden under dashboards, making instruction and learning more challenging. Because modern automobiles are becoming increasingly complex, a firm understanding of electronics and the underlying principles like Ohm's Law are a critical component of the program.
During the 2011-12 academic year, Harrell developed a new electronics exercise to provide a hands-on learning opportunity. The project requires student teams of two to develop a "cardboard circuit."
Each team received a 2'x3' piece of cardboard on which they must design and assemble at least two 12-volt circuits using automotive components. Students draw out the wiring diagram and present their project to their class.
Building on this project, students then perform electronics tests as a written exercise and then trade circuits with other teams to analyze and test a circuit board that they did not build.
"The process has definitely helped in our students' basic understanding of automotive electronics. Following the introduction of the cardboard circuit board exercise, we noticed that regular test scores improved," stated Harrell.
Evidence of the success of this project also comes from automotive faculty around the state who have not only shown interest in the project but hope to replicate it in their own programs.
Harrell's electronics assignment is a prime example of continuous improvement in action. He recognized an area where students struggle, developed a strategy and project to address that concern, and was able to measure an improvement in students' performance.
"This is not an isolated case," said MCC president Dr. Kerry Hart. "We recognize that many staff members are performing similar feats every day. It is our desire to highlight a selection of these efforts to illustrate Morgan Community College is the first and best choice for students."
