The evidence

Built on the science of how memory works

Educator isn't a hunch about what helps students revise. Its design is the two study techniques that cognitive scientists rate highest, turned into a daily habit. Here is the research — cited honestly, including where the evidence is weaker and the claims we deliberately don't make.

Retrieval practice — the testing effect

Trying to recall a fact strengthens memory far more than re-reading it. In the foundational study, students who were tested on a passage remembered 56% of it a week later, versus 42% for students who simply re-studied — and the gap grows over time.

In Educator: Every Educator card asks the student to produce an answer, never to passively re-read. That is the single most evidence-backed thing the product does.

Spaced practice — little and often

Spreading study across days beats cramming it into one block. A meta-analysis of 839 comparisons found roughly 47% vs 37% recall on average, and the advantage is largest when the test is weeks away.

In Educator: Educator is built around short daily sessions — three minutes a day — and planned re-exposure to facts, not a single long cram before the exam.

Interleaving — mixing topics

Practising mixed topics rather than one block at a time improves later performance, because it forces the brain to choose the right approach each time, the way an exam does.

In Educator: Sessions can mix topics within a subject rather than drilling one in isolation, so recall has to be discriminating, not rote.

Effortful recall beats easy re-reading

Re-reading feels productive but mostly produces a “fluency illusion”. A little difficulty — having to retrieve, with a delay — is a “desirable difficulty” that builds durable memory.

In Educator: Educator's quick-recall format is deliberately the harder, better path — short prompts that make the student think, not skim.

Less exam anxiety, not more

Frequent low-stakes quizzing is associated with lower test anxiety: in a survey of 1,408 secondary students, 72% reported that classroom retrieval practice made them feel less nervous about tests.

In Educator: Practice on Educator is low-stakes and private to the student — a rehearsal, not a test — so the format that builds memory also takes the edge off the real thing.

Motivation, designed responsibly

The evidence on gamification is genuinely mixed, and competitive leaderboards can demotivate the very students who most need encouragement.

In Educator: So Educator's student-facing gamification celebrates a student's own progress only — streaks, personal XP, rank-ups. Competitive and ranked signals stay on the teacher's dashboard, never pushed to students. A deliberate, evidence-aware choice.

Trusted by the evidence schools already use

The Education Endowment Foundation — the body most English schools turn to for “what works” — rates metacognition and self-regulation at +7 months' additional progress and feedback at +6 months, both high-impact and very low cost, with extensive evidence. A structured retrieval habit is exactly how those principles show up day to day in a classroom.

What we will and won't claim

We substantiate the method, not a grade. No revision tool — ours included — can honestly promise a particular grade, because too much else sits between practice and a result. What we can say, and stand behind, is that Educator is built on the study techniques with the strongest, most replicated evidence base in cognitive science. The classroom-scale evidence for these techniques is still maturing, and we'll keep saying so. That honesty is the point: it's how we earn a head of department's trust.

Our approach

How we turn the science into a three-minute daily habit students actually keep.

Spaced repetition, explained

Why coming back tomorrow beats one long cram — the spacing effect in plain English.

How a practice session works

The retrieval loop in action — what a student actually does in three minutes.

How our content is checked

Written to the spec, sourced, and quality-checked — never crowdsourced or AI-generated.
