Peer assisted learning: a meta-ethnographic synthesis of qualitative studies and recommendations for cardiovascular training, practice, and research.

Abstract

Introduction: Peer assisted learning (PAL) is a common method to complement more traditional teaching. Several systematic reviews and meta-analyses described the most used ways of implementation and showed that it is effective in fostering learning. A synthesis of qualitative data is missing, to highlight the perceived value by the students and to drive a successful implementation.

Evidence acquisition: The search was performed in Pubmed, Scopus and ERIC databases, with a combination of the search strings. The quality of the retrieved articles was assessed through the Critical Appraisal Skills Checklist. The analysis was performed according to the meta-ethnographic method. Fifteen articles were considered for the analysis, saturation was reached after 12 articles.

Evidence synthesis: Three main themes emerged from the analysis: PAL is effective when implemented in a safe environment, PAL is a driver of development of students' abilities and identity, and the "dark side" of PAL. Nine sub-themes emerged as components of the themes. The final line of argument highlighted the ambivalence of PAL, as an expression of the ambivalence of the still developing professional identity of students.

Conclusions: This meta-ethnographic synthesis summarizes the elements of success and the threats of PAL, a method that is particularly suitable for the cardiovascular domain. It must be implemented according to some precautions, such as organization and protected time, tutor selection, training and support, a clear integration and endorsement in the framework of the medical curriculum.
