When am I ever going to use this? An investigation of the calculus content of core engineering courses

Abstract

AbstractBackgroundMany engineering students fail to proceed through required prerequisite mathematics courses. Since these courses strongly influence engineering student attrition, we should examine to what degree these courses truly serve as prerequisites for following engineering coursework.Purpose/HypothesisWe examined two research questions: Which concepts and skills learned in calculus are applied in engineering statics and circuits homework assignments? How are calculus skills applied in engineering statics and circuits homework assignments?Design/MethodThis study analyzes the homework problems of two engineering courses—statics and circuits for nonmajors—using the mathematics‐in‐use method. These courses were chosen since they often require calculus as a direct prerequisite and are taken by most engineering majors. The mathematical content of each homework problem is carefully analyzed, with attention to alternative solution paths that may not match the instructor solution.ResultsOnly 8% of statics problems and 20% of circuits for nonmajors problems applied calculus. Furthermore, these problems applied only the simplest calculus skills (e.g., integration of polynomials).ConclusionsCircuits and statics apply relatively little calculus; most problems consist primarily of algebra. We may be able to modify prerequisite structures to ease or speed student progress.
