Embrace the Struggle
Bjork coined desirable difficulties for conditions that slow apparent learning but improve long-term retention. Effortful retrieval is the clearest example. Resist the urge to make it easier.

Why you might use it
The problem it may help with
This is the idea underneath the whole retrieval guide, so it is worth meeting on its own terms. The conditions that make learning feel hard and slow in the moment, spacing it out, mixing it up, testing instead of reviewing, are often the very conditions that make it last. The conditions that feel smooth and productive mostly produce confidence without retention.
That runs against every instinct in a helpful profession. When a pupil struggles to retrieve, the natural move is to make it easier: a hint, a prompt, a quicker reveal. Bjork's work says the struggle is doing the useful work, provided what is being asked for was genuinely taught.
What it might look like
One version of it, in a classroom
A teacher running a retrieval quiz turns the hints off and lengthens the silence before revealing answers. Pupils grumble that it feels harder than last term's version. Weeks later, the harder version is the one they remember.
Try it
A way to begin
Take one retrieval activity you already run and remove one support: the hints, the word bank, or the notes-open first pass. Change nothing else, so you can see what the added difficulty does.
What to notice
Reading what happens
- The gap between how the activity feels and what it produces. Pupils rating it harder while recalling more, later, is the effect working as described.
- Confident wrong answers. Difficulty exposes the illusion of knowing in a way smooth practice never does.
Things to think about
Before and while you use it
- Desirable difficulty is not the same as confusion. Difficulty from an unclear task or untaught content is just a barrier; the struggle has to be in the retrieving, not in working out what is being asked.
- Secure the foundations first. Effortful retrieval works on knowledge that exists, which is why the guide pairs this idea with checking that the basics are in place before pushing beyond them.
- How long to let the struggle run is not a rule anyone can hand you. That is a judgement made in the room, by the teacher who knows these students, watching whether the effort is still productive.
Technology second
Where technology fits
The card's tech line says it all: any retrieval tool, hints disabled. If the approved tool in your setting values speed, streaks or fastest-finger reveals, it's removing the desirable difficulty that makes the practice worthwhile. Retrieval is not a game show.
The wider thinking
Where the evidence sits
Bjork coined desirable difficulties for exactly this pattern, and the EEF's cognitive science review is a fair guide to how far the laboratory findings have travelled into classrooms. The card’s attribution stands as published: R. Bjork.
