Peer teaching helps both the learner and the child who teaches when the tutor is given a specific, prepared task and the teacher checks the result, but it spreads errors and wastes the tutor’s own learning time when left unstructured. The research supports it as a useful method with moderate, conditional benefits, not as a universal best method, and it must never be the only route for safety-critical knowledge.
Using older or more advanced children as tutors for younger or less advanced ones, with the structure that makes it work.
What The Research Supports And What It Does Not
Meta-analysis of tutoring programmes in schools (Cohen, Kulik and Kulik, 1982) found that tutored students generally scored better than comparison students and that tutors tended to gain as well. Later work found that students who expect to teach material process it differently and recall more of it (Nestojko and colleagues, 2014; Fiorella and Mayer, 2013). Studies of tutoring dialogue (Roscoe and Chi, 2007) found a difference in what tutors do: tutors who only recite facts gain less than tutors who explain, ask the learner questions and respond to confusion. All of these are cited from recall.
The parent article calls peer teaching “one of the most effective educational methods known”. That is stronger than the evidence: the benefits are real, but they depend on the programme being structured, the tutor knowing the material, and someone checking. Unstructured “go and teach him” often reproduces the tutor’s own misunderstandings.
Method: A Structured Tutoring Session
Step 1: Choose content the tutor has mastered. A tutor teaches what they can do without hesitation, not what they half know.
Step 2: Prepare the tutor. The teacher spends a few minutes before the session showing the tutor the task, what a correct answer looks like and what to say when the learner is wrong. A script helps: ask, wait, prompt, praise specifically, move on.
Step 3: Give a bounded task. For example, ten flash cards of letter sounds, or one measuring exercise with a rope.
Step 4: Check at the end. The teacher asks the learner to show what was learned, not the tutor to report it.
Step 5: Rotate roles. In pairs of similar skill, each tutors a different topic so no child is permanently the helper or the helped.
Worked Example
Two children, one more advanced in reading. The teacher gives the older child a set of word cards from the decodable list (Tier 1: Survival Literacy), shows the prompt “sound it out” and sits the pair within earshot. The older child learns to hold back from supplying the word; the younger child reads aloud with a patient listener. The teacher’s check at the end is one minute of listening to the younger child read a card cold.
Costs And Risks
- Error propagation. A wrong plant name, a wrong measure or a wrong rule is repeated with authority. For critical topics such as medicine, poison plants and fire, peer teaching is a supplement to adult teaching and never a replacement. See the warning in Teaching Methods.
- Exploitation by default. Making older children into unpaid teachers every day takes their learning and play time. See Avoiding Exploitation.
- Status damage. A child corrected in public by a peer may feel shamed. Teach tutors to correct kindly and in private where possible.
- A tutor with a gap. Teaching exposes what the tutor does not know; give them a route to ask the teacher.
Common Mistakes
- No time for the tutor to prepare.
- No check at the end.
- Using the same child every time.
