Engineers are problem solvers. Models of successful problem solving in engineering include steps of choosing equations, monitoring, and evaluating problem solutions, and the combination of these steps into more complex problem-solving strategies. These are metacognitive processes because they require the solver to think about anticipated, ongoing, and final problem-solving steps. Although research has identified characteristic differences between novice and expert problem solvers, less is known about the more detailed ways in which students develop their problem-solving methods through experience. In this research project, we asked 1) Which problem-solving strategies do students report using, 2) Is strategy use correlated with level of metacognitive reflection and problem-solving confidence, 3) Is strategy use correlated with objective measures of problem-solving ability, and 4) Do problem-solving steps cluster into more complex strategies. Participants in the present study were 101 chemical engineering seniors who completed a 3-credit course that reviewed eight major Fundamentals of Engineering (FE) Chemical topics (i.e., material balances, energy balances, mass transfer, heat transfer, fluid mechanics, reaction engineering, material sciences, and process control) in order to prepare for taking the FE exam. At the conclusion of each topic, students responded to a number of survey questions, including 1) Briefly describe the problem-solving strategies you employed to solve the FE practice problems, 2) On a scale of 1-5, how reflective (metacognitive) were you when solving this assignment, and 3) On a scale of 1-5, indicate how confident you were after solving the [practice] problems. Additionally, students completed a mock FE examination as a measure of problem-solving ability. Qualitative data-analytic methods were used to code responses, which included: understanding the problem, choosing a method, constructing a mental model, checking work, and drawing on supplemental resources. The paper reports frequencies of specific strategy steps and strategy clusters, and correlations of problem-solving steps and more complex strategies with metacognitive reflection, confidence, and the FE exam. This study provides a detailed description of student cognitions and the ways in which those cognitions might cluster into more complicated networks of problem-solving steps. It takes a first step in understanding the relationships between metacognitive reflection, confidence, strategies, and problem-solving performance, in training engineering students.
