Spaced Repetition: The Science of Active Recall Have you ever crammed for an exam, passed it, and then forgotten everything a week later? This is due to the Forgetting Curve, a mathematical formula showing how memory declines over time if there is no attempt to retain it. The most effective way to combat this is through two evidence-based study methods: Active Recall and Spaced Repetition. What is Active Recall? Active recall is the process of actively testing your brain to retrieve information, rather than passively reading notes or highlighting textbook pages. • Passive Study: Re-reading a chapter on Newtonian Physics. Active Study: Closing the book and asking yourself: "What are Newton's three laws?"* Retrieving the information strengthens the neural pathways in your brain, cementing the knowledge. How Spaced Repetition Works Spaced repetition involves reviewing the material at increasing intervals over time. For example: • Review 1: 1 day after learning. • Review 2: 3 days after learning. • Review 3: 7 days after learning
