Evidence-Based Study Techniques for Kenyan Students

The seven study techniques cognitive science has proven work — spaced repetition, retrieval practice, interleaving, dual coding — adapted for the KCSE, CBC and university student.

The science of how memory actually forms

Memory has three stages: encoding, storage and retrieval. Re-reading helps the first two but not the third — and the exam tests only retrieval. That is why students who read for hours still freeze when they see the paper.

The seven techniques that work

1. Retrieval practice. Close your book. Write down everything you remember. Then check. Do this daily.
2. Spaced repetition. Review new material at 1 day, 3 days, 7 days and 14 days. Use Anki or paper flashcards.
3. Interleaving. Mix topics in one session (algebra → trigonometry → statistics) instead of blocking one topic for hours.
4. Dual coding. Pair words with diagrams — the brain stores them twice.
5. Elaboration. For every fact ask "why is this true?" and answer in your own words.
6. Concrete examples. Replace abstract definitions with a Kenyan example — explain inflation using sukuma wima prices.
7. The Feynman technique. Teach the topic to a Form 2 sibling. If they don't understand, you don't either.

What does not work

Highlighting, copying notes word-for-word, listening to recorded lectures while doing other things, and "studying" with friends who are on Instagram. These feel productive but produce almost no retrieval improvement.
