What does research on memory retrieval have to offer Montessori education?
A child can complete a beautiful Montessori lesson, return the material independently, and still struggle to remember the concept several days later. This is not necessarily a failure of the lesson—or the child. It is a reminder that understanding something in the moment and being able to retrieve it later are different learning challenges.
Cognitive science supports that rereading or reviewing information is not the same as bringing it back to mind. There are some strategies that specifically target later retrieval of information, though, that can be incorporated as independent work for period three practice of lessons. Building in intentional retrieval practice can support learning (Agarwal et al 2021), and format, strategy, and implementation matter. For example, Dunlosky and colleagues (2013) identified practice testing (students quizzing themselves and checking their answers) and distributed practice (short spread out repetitions for practice vs. one long practice session) as particularly useful approaches across learning contexts.

Montessori teachers may hear “practice testing” and imagine timed quizzes, competitive scores, or a disruption to the work cycle. None of those is required. Retrieval practice simply means inviting the learner to recall something before being shown the answer again. The important cognitive work is the act of remembering. We don’t actually remember things better by “putting it in our brains” over and over again (such as re-reading), we remember things better by repeatedly trying to pull the information “out” of our brains.
Consider a child who has explored equivalent fractions with the fraction circles. The next day, rather than immediately presenting the circles again, we might ask, “Yesterday you found two different ways to make one-half. What do you remember?” The child could explain, sketch, gesture, or select materials to reconstruct the idea. Only afterward might we revisit the circles together. The prompt is brief, purposeful, and rooted in the child’s own work, and this aligns with Montessori’s principle of our spiraling curriculum: building new knowledge onto prior knowledge. It also allows teachers a moment of formative assessment to make sure the prior knowledge we are assuming is really there.
In a lower elementary classroom, a guide might ask a child to reconstruct the steps of a bead-chain exploration or recall the names of parts of a flower before consulting a chart. In upper elementary, children could begin a research meeting by telling a partner what they remember from yesterday’s reading before opening their notebooks. These moments need not become mandatory whole-group exercises. They can emerge in conferences, small-group follow-ups, or self-chosen review work.
As Montessorians, it is important to maintain a balance, though. Retrieval practice is not a reason to replace exploration with memorization. Montessori materials give children sensorial and conceptual experiences that are not reducible to factual recall. Nor should a child who cannot retrieve an answer be made to perform publicly or repeatedly experience failure. Supportive feedback, a clue, or a return to the material can make retrieval both more successful and more humane, offering the child scaffolds to success.
Spacing matters, too. A brief return to an idea after a day, a week, and later in the month may strengthen durable learning more than several repetitions in one sitting. A teacher’s observation notes can help identify which ideas deserve revisiting, while the child retains meaningful choices about how to engage.
Perhaps the most Montessori-compatible way to think about retrieval practice is this: We are not asking children to prove they learned something for our benefit. We are offering them opportunities to discover what their minds can now bring forward independently. The guide’s task remains to observe, invite, and adjust—not to turn every encounter into a test.
