Problem-based learning, critical thinking and concept mapping in speech-language pathology education: A review

Despite speech-language pathology (SLP) education undergoing many innovative changes over the years, there has been little research about learning or outcomes in SLP programs. Critical thinking in clinical decision-making, however, has been identified as a critical skill in SLP. Several recent studies have shown that concept mapping can be used to assess, and perhaps enhance, critical thinking. Problem-based learning (PBL) is reported to be one way to encourage critical thinking and life-long learning. Here we review the literature in PBL, concept mapping, and critical thinking, focusing on the education of SLP students. The review illustrates the close and complex interactions amongst problem-based learning, critical thinking and concept mapping. The aim of the review is to provide a better understanding of the mechanism of PBL, and to increase understanding regarding why the employment of PBL in SLP programs may facilitate critically-thinking graduate clinicians. The evidence indicates that PBL allows more meaningful learning that promotes better integration between theory and clinical practice.
