Abstract

Problem-based learning (PBL) is resource-intensive, but promotes skills like uncertainty tolerance, and knowledge application (e.g. (1)). During curriculum review at two UK Medical Schools, we explored Year 1 medical undergraduates’ learning in PBL. Threshold Concepts (TCs) are widely-studied across disciplines, less-so in Medicine (2). TCs are integrative, irreversible, and troublesome (3). They differ from ‘core concepts’ in being crucial for subject mastery, and transformative (“change in knowing, doing, being, and future learning”) (4). Without them, students can get stuck in a ‘liminal’ state of oscillating or incomplete understanding, experiencing uncertainty and discomfort, mimicking understanding (6). PBL may enable students to learn Troublesome Knowledge (TK, (5)) and TCs, in several ways (7, 8). PBL itself may constitute a ‘Threshold Capability’ (7). We therefore explored PBL learning in relation to the TC and TK models, and asked what promotes or hinders learning. We compared results between two Schools, to identify commonalities, and explore differences that may arise from variations how PBL is enacted. Students (n= 19) recorded instances during PBL that meet criteria based on the TC definition (3,9) (e.g. struggles, frustration, coming together, seeing things differently, aha moments) To avoid bias, TCs were not mentioned. Tutors (n=12) also recorded any such instances. ‘Straight-after-the-moment’ audio-diaries minimised hindsight bias (10). Data analysis was as in Neve et al (7): focused on the TC Framework; but allowing for emergent coding categories and alternative theories. A priori codes included each TC criterion (3,9), enablers and barriers to learning; emergent codes included aspects of PBL and subject areas. Codes and themes were compared between Schools. At both sites, students identified learning instances that involved characteristics of TCs and/or TKs, at multiple stages of PBL. Both content knowledge and PBL skills were identified. Tutor accounts provided confirmation and additional insights. However, the number of areas identified and extent to which they met the TC definition, differed between Schools. We describe learning areas identified; and discuss implications for SoTL in three areas: Medical Education, Threshold Concepts, and PBL. We give evidence of how PBL can help students learn troublesome and threshold concepts, and of methods can enable and hinder this; and discuss methodological limitations of our study. We consider the role of PBL in undergraduate medical curricula at both Schools, and beyond. Finally, we demonstrate the utility and limitations of the TC framework, adding to critical debate (4) about the definition and identification of TCs.
