What Good Learning Evidence Looks Like

A critical evidence review on appraising learning claims: separate the assertion from its study design and limits, and weight evidence by replication.

Everyone in learning cites evidence, and much of it does not survive a second look. Good evidence is not a study that agrees with you; it is a claim whose design, sample and limits you can actually see. This guide sets out what good learning evidence looks like, using an appraisal table that separates the claim from the study behind it. Its boundary is motivation in online learning, which has its own evidence and practice piece.

A claim is only as good as its design

Effect sizes mean little without the design that produced them. A large effect from a tiny, short, unblinded study is weaker than a modest effect from a careful one. The What Works Clearinghouse publishes standards and procedures for judging the strength of education evidence. [c-wwc] Those procedures give you a shared way to say how much confidence a claim has earned.

Columns that keep evidence honest

• Claim and source: the exact assertion and where it comes from, so it can be traced rather than paraphrased into vagueness.

• Design and sample: how the study was run and on whom, which sets the ceiling on what it can support.

• Comparator and effect: what the intervention beat, by how much, and with what uncertainty.

• Transfer limits: the settings and learners the result does not automatically cover.

Prefer durable findings over novelty

The strongest classroom evidence tends to be unglamorous and repeatedly confirmed, not the latest single result. Evidence summaries for teaching consistently stress diagnosing what a learner understands before choosing how to intervene. [c-eef] Weighting evidence by how well it replicates, rather than how new it is, protects you from chasing noise.

Where DoviLearn® fits

Design decisions described under DoviLearn® research can be read through this appraisal table: ask which claims are backed by what design, and where the transfer limits sit, with adaptive delivery under DoviLearn® learning technology . The standards and the judgement stay with educators and organisations, and the example shows a process rather than guaranteed learning, employment or business outcomes.
