Evaluating the Dynamics of Learning Approaches: A Systematic Review Investigating the Nexus Between Teaching Methods and Academic Performance in Medical and Dental Education

In recent decades, a noticeable trend has emerged in medical and dental schools to adjust their curricula to promote learning strategies and habits geared towards long-term knowledge retention. This systematic review therefore sought to examine whether different teaching methods influence students' preferred learning approaches (deep, strategic, and surface approach) and indirectly affect their academic performance. Furthermore, it provides a comprehensive overview of the inconsistencies evident in previous literature regarding the relationship between learning approaches and academic performance of medical and dental students. A thorough search across eight databases yielded 49 relevant studies published between the years 2000 and 2023. The majority of studies revealed that whilst deep and strategic learners tend to excel at medical or dental school, surface learners appear to struggle under intense workload and pressure. Hence, a common consensus emerged amongst the existing literature that there is a relative benefit in attempting to guide students towards deep and strategic learning habits and to minimise surface-related learning strategies. However, results also conveyed that merely modifying the teaching methods used in medical and dental schools has limited merit. As such, the results emphasised the lack of a 'one-size-fits-all' teaching method. Common factors influencing learning approaches were subsequently identified, and based on these findings, an outlook was put forth to integrate a cognitive neuroscience approach into higher education. These directions for future investigations aim to help students reach their full potential by understanding the processes underlying efficient learning and by being mindful of respective encouraging and discouraging factors.
