Active Recall: What It Is, Why It Works, and How to Use It
High — practice testing rated highest utility in Dunlosky et al. 2013 meta-analysis; Karpicke & Blunt 2011 showed one retrieval session outperforms four rereading sessions; Roediger & Karpicke 2006 found ~50% better delayed retention for retrieval vs. re-study groups evidenceActive recall — testing yourself to pull information from memory rather than passively reviewing it — is the most evidence-backed study technique available, yet most students avoid it because difficulty feels like inefficiency. This guide explains the science, walks through six practical techniques, and helps you understand why passive study methods like rereading and highlighting create a false sense of mastery.
