Active learning ideas

Web Credibility and Search

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.

Activity 01

• Case Study Analysis
• 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.

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.

What to look for

Provide students with two short descriptions of websites about the same topic, one credible and one less so. Ask them to write one sentence explaining which is more credible and list two reasons why.

Activity 02

• Case Study Analysis
• 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.

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.

What to look for

Pose the question: 'Why might your search results for 'best video games' be different from your friend's results?' Guide students to discuss factors like past searches, location, and personalization.

Activity 03

• Simulation Game
• 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.

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.

What to look for

Show students a search engine results page for a common query. Ask them to identify one website that looks reliable and one that looks less reliable, explaining their reasoning based on title or snippet.

Activity 04

• Case Study Analysis
• 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.

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.

What to look for

Provide students with two short descriptions of websites about the same topic, one credible and one less so. Ask them to write one sentence explaining which is more credible and list two reasons why.

A few notes on teaching this unit

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.

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.

Watch Out for These Misconceptions

• During the Scavenger Hunt, watch for students assuming the top result is always the best.

  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.

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

  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.

• During the Personalised Search Swap, watch for students assuming everyone sees identical results.

  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.
