Evaluate an online source
Source evaluation concerns a specific claim in a specific context. A professional-looking page, a familiar logo or a large following cannot replace checking what the evidence actually says.

A worked example
A webpage claims a training activity improves exam results and links to a study about reaction time. Open the study and compare its outcome, population and activity with the webpage’s claim. Even a genuine study may not support that wider conclusion. Record the mismatch and look for a source that addresses the actual outcome.
Try it in three steps
- Locate the original evidence.
- Compare the claim with the measured outcome.
- Check context, interests and independent support.
What to watch for
Avoid an automatic trust score that hides judgement behind a number. Write the reason for accepting, limiting or rejecting the particular claim.
Apply it to your own material
Choose one topic from your current course or project. Write down the question you want to answer, make an attempt, and keep a note of how you checked it. Use the example above as a pattern; replace its subject matter and assumptions rather than copying an answer into a different task.
