The contribution of evidence-based practice to educational activities

Abstract

Introduction This chapter examines issues relating to evaluation of educational interventions. It considers the types of questions that might be framed from an educational perspective, the sources that might supply answers to such questions, and the quality of the evidence base. Whether evidence from education research is put into practice, and barriers to acting on the evidence are also considered. Key studies from within the domain are used to illustrate issues and methods. Educational approaches within an information setting encompass everything from user education to staff development and training. A subsequent special topic examines the evidence base for the training of users in information skills. What is evidence-based education? What do we mean by evidence-based education, and what kinds of research might those involved in teaching and learning do? Much existing published research centres on education policy, and very little is actually evidence-based. In addition, much research has been carried out in the context of primary and secondary education, where much of the controversy and public interest lies. In fact, even here Davies et al. (2000) suggest that the evidence base is weak and that ‘there is often not a culture of teachers using research to inform their everyday school practice’. In this chapter we focus on research undertaken with regard to adult and lifelong learning. However we should acknowledge, albeit in passing, the considerable work that exists looking at evidence-based practice in relation to the contribution of the school librarian (Todd, 2001; Todd, 2002a; Todd, 2002b; Todd, 2003). Evidence-based education is ‘(t)he integration of professional wisdom with the best empirical evidence in making decisions about how to deliver instruction’. The authors of this definition argue that professional wisdom is important for helping to adapt empirical evidence to local situations, and that randomized control trials are the best way to establish empirical evidence. Fierce debate surrounds the relevance and appropriateness of research methodologies for educational interventions. Some see the gold standard of evidence in this context as multiple replications of small scale, randomized controlled trials of feasible interventions in real-life settings (Fitz-Gibbon, Tymms and Coe, 2000) while others strongly challenge this view (Morrison 2001; Hammersley 2001).
