Homework often gets a bad reputation and is neglected. It’s seen as repetitive and unnecessary. But when you look at how learning actually works, homework plays a much more important role than many people realise, especially when combined with a technique called spaced repetition.
When you first learn something in class, your brain only stores it temporarily. Without revisiting that information, it fades quickly, you forget approximately 70% of all new information that isn’t reinforced with 24hrs of learning it. This is where homework becomes valuable. By reviewing and applying what you learned shortly after class, you reinforce those neural connections and make the memory stronger.
Spaced repetition takes this idea even further. Instead of cramming everything in one long study session, you revisit the material multiple times over increasing intervals, like after one day, then three days, then a week. Each time you review, your brain has to work a little harder to recall the information, and that effort actually strengthens your memory.
Homework naturally supports spaced repetition when it’s assigned regularly. A few problems each day or short review tasks spread across a week are far more effective than a single large assignment. This steady exposure helps move knowledge from short-term memory into long-term storage.
Another benefit is confidence. When you repeatedly engage with material over time, it starts to feel familiar. You’re not just memorising you’re understanding. This makes it easier to recall information during exams or real-life situations.
Homework isn’t just about completing tasks it’s about building lasting knowledge that you will remember. When paired with spaced repetition, it becomes one of the most powerful tools for learning and remembering effectively you can also use online digital tools to help you and automatically set reminders for you to revise such as; Anki.
