Abstract
BACKGROUND: Teaching the steps of evidence-based medicine (EBM) to undergraduate as well as postgraduate health care professionals is crucial for implementation of effective, beneficial health care practices and abandonment of ineffective, harmful ones. Stellenbosch University in Cape Town, South Africa, offers a 12-week, completely online module on EBM within the Family Medicine division, to medical specialists in their first year of training. The aim of this study was to formatively evaluate this module; assessing both the mode of delivery; as well as the perceived effectiveness and usefulness thereof.Entities:

1Judgements about adequacy of material related to content on EBM enabling and key competencies, which we compared to the material used in the EBM module.
2According to Miller’s pyramid of competence [27,28].
3According to EPIC scale that measures self-perceived EBM competence on a scale from 0% (no confidence) to 100% (completely confident).
4Based on Likert score ratings of EBHC statements adapted from Baum (2003), from strongly disagree to strongly agree.
