## Match learning support to what the learner already knows

The same amount of help can teach one learner and slow another down.

### Use when

- You are choosing how much explanation, prompting or step-by-step help to give before practice.

### Avoid when

- Prior knowledge is task-specific. Seniority is not a safe substitute for a diagnostic. Effects also varied across domains and study designs.

### Explanation

A 2025 meta-analysis found that instructional help interacts with prior domain knowledge: learners with less knowledge benefited from more assistance, while learners with more knowledge benefited from less. Treat support as a variable. Check what the learner can already do on the target skill, then use the lightest support that makes productive practice possible.

### Steps

1. Use a short diagnostic task before choosing the support level.
2. If the learner cannot see the method, add a model, worked example, prompt or partial solution.
3. If they can already perform it reliably, move toward independent problems and feedback.
4. Recheck after several attempts instead of keeping the support level by habit.

### Example

Two analysts are learning the same SQL join. One cannot build it, so an annotated solved query helps. The other can already write it correctly and gains more from a new case without the template.

### Check

The learner's support level is based on demonstrated knowledge of the target task, and it changes when unaided performance changes.

### Limits

- Prior knowledge is task-specific. Seniority is not a safe substitute for a diagnostic. Effects also varied across domains and study designs.

### Evidence and sources

- supports: A 2025 meta-analysis of 60 experimental studies found that learners with low prior knowledge learned more under high-assistance instruction, while learners with high prior knowledge learned more under low-assistance instruction. — RS-9DEAEED4E09611178CBC. The pooled effects were highly heterogeneous, and assistance covered different instructional designs rather than one universal method. (Abstract and main results)
