Abstract
The aim of this study was to track students’ critical thinking performance longitudinally through concept map analysis in a problem-based learning (PBL) curriculum. Concept map analysis has been employed in the assessment of students’ critical thinking in medical education. Little is known concerning concept mapping (CM) in speech-language pathology (SLP) education. In this quantitative study, students in a 4-year SLP education program (N = 38) were followed until the completion of a fully-integrated PBL curriculum from Years 1 to 3. Students’ concept maps were analyzed using a tool developed for this study, the Concept Map Assessment Profile (CMAP). There was an increase in concept map scores across the 3 years at the beginning of the academic year. The CM performance over the 3 years predicted 21.0% to 33.6% of variance in three measures of learning outcomes. The CMAP is a reliable measure, with strong inter-rater and intra-rater reliability (r = 0.85 and r = 0.96, respectively). In addition to its use as an assessment tool, the CMAP might be used to facilitate students’ learning as feedback concerning strengths and weaknesses in the development of critical thinking can be provided.
