Our brains are wired to forget, but there are research-backed strategies you can use to make your teaching stick!

#EduSkyWe often think of memories as books in a library, filed away/accessed when needed.
But they’re actually more like spiderwebs, strands of recollection distributed across millions of connected neurons. 🕸️

When we learn something new, the material is encoded across these neural networks, converting the experience into a memory.

Psychologist Hermann Ebbinghaus found that without any reinforcement or connections to prior knowledge, information is quickly forgotten—roughly 56% in one hour, 66% after a day, and 75% after six days.
So what can be done to preserve the hard work of teaching?

Two scientifically based ways to help students retain learning: making as many connections as possible—typically to other concepts, thus widening the “spiderweb” of neural connections—but also by accessing the memory repeatedly over time.

The following learning strategies, all tied to recent research, are effective ways to do that:

When students explain what they’ve learned to peers, fading memories are reactivated, strengthened, and consolidated.
This strategy not only increases retention but also encourages active learning.

⭐ The Spacing Effect
Instead of covering a topic then moving on, revisit key ideas throughout the year. Research shows students perform better academically when given multiple, spaced opportunities to review learned material.

📝 Frequent Practice Tests
Giving frequent, low-stakes practice tests can boost long-term retention and help reduce stress, which often impairs memory performance.
These can even be ungraded—a pop quiz at the start of a lesson or a trivia quiz on Kahoot, for example.

It’s often easier to remember information that’s been presented in different ways, especially if visual aids can help organize information.
Students are more likely to remember what’s been read *and* seen, instead of either one alone.
