Ever noticed your students seem to get it one day… and forget it the next? That was kind of rhetorical and of course it's not a reflection on your teaching; it’s how memory works. Our brains are designed to forget things we don’t revisit.
Spaced retrieval interrupts that forgetting curve. Instead of revising everything at once, students revisit key concepts just as they fade, at the optimal moment for memory to strengthen. Each “memory rep” builds stronger neural connections and helps to shift knowledge into long-term memory.
Spaced retrieval is one of the most effective teaching and learning strategies (effect sizes between 0.62 and 0.74 across hundreds of studies) for helping students master, and remember, what they learn. However it's near impossible to do without help.
That’s why we’ve embedded spaced retrieval into our daily teaching system. Without lifting a finger, students get the right questions, at the right time, drawn from the right lessons, making every moment of revision count.
When memory sticks, confidence builds, and results follow.
We’ve spent over a decade building a system that learns from how your students learn.
Every week, Edrolo spaced retrieval scans each class’s engagement across every lesson—how many students have watched video lessons, attempted questions, how well they’ve done, and how long it’s been since they last engaged.
If students haven’t seen a topic at all (as in it’s not been taught and thus wouldn’t make sense to revisit), it gets skipped. If students seem rusty on something, we boost it. If they’ve just done it, we let it breathe.
Combined with the research and science of spaced retrieval, these signals tell us what topics students are in danger of forgetting, creating a list of what to revisit. The most relevant questions are selected, and we adjust the difficulty based on how the class has performed. Strong classes get stretched, and struggling ones get scaffolded.
It’s all designed to help students build and retain knowledge over time—automatically.
Teachers focus on teaching. We’ll handle the spacing.
Want to automate the impossible? Spaced retrieval is currently available in almost 40 Edrolo courses - see the complete list here. Get in touch to find out more or for a quick demo of how it can help boost learning and unlock results for your students.
