Web Credibility and SearchActivities & Teaching Strategies

Active learning works for this topic because students need hands-on experience to see how search engines and websites function in real time. Moving beyond theory helps them connect abstract concepts like algorithms and bias to concrete examples they can evaluate themselves.

Learning Objectives

  1. 1Analyze how search engine algorithms prioritize and rank website results.
  2. 2Differentiate between reliable and unreliable online sources based on specific criteria.
  3. 3Explain why search results can vary for different users based on personal data.
  4. 4Evaluate the credibility of a website by checking its author, date, and sources.

35 min·Pairs

Scavenger Hunt: Reliable Facts

Provide a list of five questions on animals or history. In pairs, students search using refined queries, select top three results, and note why each is reliable or not. Pairs present one finding to the class, justifying their choice with evidence like author credentials.

Prepare & details

Analyze how search engines decide which websites to show at the top of the list.

Facilitation Tip: In the Scavenger Hunt, circulate and ask guiding questions like 'How did you decide this site is reliable?' to push deeper thinking.

Setup: Groups at tables with case materials

Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template

45 min·Small Groups

Website Detective Stations

Set up four stations with printed websites: news, blog, wiki, ad-heavy site. Small groups rotate every 10 minutes, using a checklist to score reliability on domain, date, sources. Groups compile a class chart of patterns found.

Prepare & details

Differentiate between reliable and unreliable websites.

Facilitation Tip: At Website Detective Stations, assign roles such as 'date checker' or 'bias spotter' to ensure every student participates actively.

30 min·Whole Class

Algorithm Simulation Game

As a whole class, role-play a search engine: students propose websites for a query, vote on ranking factors like popularity and relevance. Teacher facilitates tallying votes, then reveals real engine criteria for comparison and discussion.

Prepare & details

Explain why different people get different results when searching for the same thing.

Facilitation Tip: During the Algorithm Simulation Game, pause after each round to discuss how small changes in search terms altered the results.

Setup: Flexible space for group stations

Materials: Role cards with goals/resources, Game currency or tokens, Round tracker

25 min·Individual

Personalised Search Swap

Individually, students search a neutral term like 'pasta' twice: incognito and logged in. They note result differences, then swap devices with a partner to test and discuss location or history influences in pairs.

Prepare & details

Analyze how search engines decide which websites to show at the top of the list.

Facilitation Tip: In the Personalised Search Swap, model how to compare results side-by-side before students work in pairs.

Teaching This Topic

Teachers should avoid presenting search engines as neutral tools. Instead, use simulations and real-time examples to show how algorithms personalize results. Research suggests students grasp these concepts better when they experience the variation directly rather than being told about it. Keep discussions student-centered by asking them to justify their choices with evidence from the websites they examine.

What to Expect

Successful learning looks like students confidently explaining why search results vary, identifying credible sources, and refining their own searches. They should use key terms like 'keywords,' 'bias,' and 'authorship' when discussing websites and algorithms.

These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions

Common MisconceptionDuring the Scavenger Hunt, watch for students assuming the top result is always the best.

What to Teach Instead

Use the hunt’s ranking comparison task to ask students to explain why lower-ranked results might be more reliable, referencing their checklist criteria like publication date or author credentials.

Common MisconceptionDuring Website Detective Stations, watch for students trusting .gov or .edu sites without further checks.

What to Teach Instead

Have students rotate through stations with varied examples and explicitly compare outdated .gov content to a current, well-sourced blog to highlight that domain alone isn’t enough.

Common MisconceptionDuring the Personalised Search Swap, watch for students assuming everyone sees identical results.

What to Teach Instead

After the swap, ask pairs to share differences they noticed and connect these to personalisation factors like location or past searches discussed during the activity.

Assessment Ideas

Quick Check

During the Scavenger Hunt, ask students to point to one reliable website and one unreliable website from their results, explaining their reasoning based on the criteria checklist.

Discussion Prompt

After Website Detective Stations, facilitate a class discussion where students debate why a seemingly credible website might still contain bias or outdated information, using examples from their station work.

Exit Ticket

After the Algorithm Simulation Game, provide a short exit ticket with a simulated search results page. Ask students to circle one result they would trust and explain their choice using terms like 'keywords,' 'relevance,' or 'bias'.

Extensions & Scaffolding

  • Challenge students to create a fake website with misleading information and swap with a peer for evaluation.
  • Scaffolding: Provide a partially completed credibility checklist for students who struggle to identify key elements like authorship or publication dates.
  • Deeper exploration: Invite students to research how search engines use cookies or location data to personalize results and present findings to the class.

Key Vocabulary

AlgorithmA set of rules or instructions that a computer follows to solve a problem or complete a task, like deciding which websites to show first.
CredibilityThe quality of being trusted and believed; how reliable or believable information or a source is.
BiasA tendency to favor one thing, person, or group over another, which can affect the information presented.
SourceThe place or person from which information is obtained; checking the original source helps determine reliability.
