Abstract

Using Degrees of Freedom as a Pervasive Strategy for Improving Problems SolvingJoseph Biernacki, Chemical Engineering, Tennessee Technological University, Cookeville, TNChemical engineering educators have known for decades that the degrees of freedom conceptis a powerful tool for organizing the solution of complex problems involving mass and energyconservation. Unfortunately, the degrees of freedom concept seems to be relegated to ourcourse on heat and material balances and then somehow forgotten elsewhere. Withoutsuitable practice, most chemical engineering students will lay aside the degrees of freedomformalisms that most learn in their sophomore year and will revert to hunt-and-peck strategiesfor solving problems, even when properly trained originally. A more pervasive and deliberateapproach, however, is needed if we expect to improve problem solving skills and impart lasting“ways of being” in our students. A number of structured examples will be presented toillustrate the utility of the degrees of freedom concept across curricular content
