Evaluating the problem-solving skills of graduating chemical engineering students

Research has shown that engineering students may not be learning to solve the kinds of complex prob-lems they will be required to solve as practicing engineers ("authentic problems"). Though it is widely believed that we teach engineering problem-solving throughout the undergraduate chemical engineering curriculum, this has not been tested. In this study we use a new instrument for measuring the authen-tic problem-solving skills of graduating seniors in chemical engineering at two different universities in the context of chemical process design. We find large variations across different areas of process design problem solving as to how expert-like students are in general, and variations between the two insti-tutions. Students were able to identify the same safety issues as experts, but they were conspicuously "nonexpert" in other areas, such as in identifying the important features of a design problem. By exam-ining the respective curricula at the two institutions, we are able to show how the variations both within and across institutions in the specific problem-solving skills students master matches with the practice they get during their undergraduate careers. The results imply that more thoroughly integrating practice in authentic design and problem-solving decisions into the undergraduate curriculum would result in students graduating with capabilities more comparable to those of skilled engineers.
