Fraction and whole number symbolic and non-symbolic numerical magnitude understandings were measured using both…

Introduction: We undertook a meta-analysis of the Continuing Medical Education (CME) outcome literature to examine the effect of moderator variables on physician knowledge, performance, and patient outcomes. Methods: A literature search of MEDLINE and ERIC was conducted for randomized controlled trials and experimental design studies of CME…
