Evaluate the Source

A trending article is spreading fast, but something about it doesn't add up. Analyze the evidence, crack four locks, and decide whether the source can be trusted.

The premise

Anyone can post anything online, so a sharp digital citizen investigates before they believe or share. Work through the case files, weigh the evidence, and open all four locks. Each lock carries a reason that shows exactly why the answer holds up.

How this breakout builds CLEAR thinking

Every Critical Thinking Online Breakout runs on the CLEAR process — Claim, Lens, Evidence, Alternatives, Response (full framework). Here is where students practice each step in this activity:

  • Claim — for each lock, decide what answer it is really asking for, and make it specific.
  • Lens — notice what you already assume before you choose.
  • Evidence — weigh the six clues; “The Router” is true but off-topic, so it is not evidence for any lock.
  • Alternatives — the multiple-choice and multi-select locks force a comparison of competing options.
  • Response — the reason revealed after each lock models the justified answer to act on.

In the classroom

  • Warm up (5 min). Ask: “Become a Source Analyst” — what does this mean online? Surface prior experience before the activity.
  • Model one clue. Open a single clue together and think aloud: what does this tell us, and which lock might it help?
  • Reason, don’t guess. Require students to say why before checking a lock. After each solve, read the revealed reason and compare it to their thinking.
  • Spot the decoy. One clue is true but useless. Debrief which one and how they knew — a core evaluation skill.
  • Language support. The 🌐 picker offers 7 languages; pair newcomers to discuss clues in their home language, then answer.
  • Extend. Have students write a new clue, or a real-life example, for the focus skill they found hardest.
