Classrooms should replace learning-style matching with evidence-based strategies like spacing and retrieval practice. Teachers should spread learning across multiple lessons and regularly prompt all s

Q: What should teachers do instead of matching students’ learning styles?

Instead of matching students’ learning styles, teachers should use a variety of evidence-based teaching methods, such as lectures, readings, essays, interactive presentations, and real-world projects.

An Educator's Guide to Spaced and Retrieval Practice

About this Capsule

Much of what schools and parents assume about learning, including learning styles, doesn't survive testing. These strategies center on what does: spacing practice over time, recalling material instead of rereading it, and lesson designs backed by experiments. Comparing them shows where to put effort so kids actually remember what they learn.

“What's the difference between spaced and massed practice, and how much does it actually matter for kids' learning?”

Generic AI

“Massed practice means doing a lot of practice in one block, with little or no break between repetitions.

Example: studying 20 spelling words for 60 minutes on Thursday night before Friday’s test.

Spaced practice means spreading practice across multiple shorter sessions over time.

Example: studying those same words for 10–15 minutes each day across the week.

The basic difference

Massed practice often feels more efficient in the moment because kids improve quickly during the session. But a lot of that improvement is temporary. Spaced practice usually feels slower and sometimes harder, but it leads to better long-term retention.

A simple way to put it:

Massed practice helps performance right now.
Spaced practice helps learning stick.

How much does it matter?

It matters a lot, especially if the goal is remembering or using knowledge later. The “spacin...”

“Spaced practice matters a lot: in a meta-analysis, spaced retrieval practice beat massed retrieval practice by Hedges’ g = 1.01; even after correcting for publication bias, the effect was still strong at g = 0.74. For kids specifically, a study with 5–7-year-olds found that one lesson per day for four consecutive days produced better learning and generalization than doing four lessons back-to-back on the same day—and the advantage was still visible one week after the last lesson.

The difference

Massed practice means learning or practicing the same material in one concentrated block.

Example: A child studies spelling words for 40 minutes on Monday.
Classroom version: Four lessons taught in immediate succession on the same day.
It can feel productive because the material is fresh, but that fluency can create an illusion of mastery.
