Effective Search Strategies

Active learning works because search strategies are skills pupils must practice, not facts they can absorb passively. When students actively refine queries in pairs or evaluate sources in groups, they experience firsthand how search engines interpret language and prioritise information.

Activity 01

• Outdoor Investigation Session
• 25 min · Pairs

Pairs Challenge: Query Refinement

Pairs start with a broad topic like 'animals'. One pupil searches first, then both refine using keywords or quotes, noting result changes. They discuss which query works best and why. Share top findings with the class.

Analyze how a search engine prioritizes results for a given query.

Facilitation Tip

During the Pairs Challenge, circulate and listen for pairs explaining why their refined query is better, prompting them to justify their word choices.

What to look for

Present students with a simple research question, like 'What is the tallest building in London?'. Ask them to write down two different search queries they would use to find the answer. Then, have them explain which query they think will give a better result and why.

Activity 02

• 35 min · Small Groups

Small Groups: Reliability Hunt

Assign a research question per group, such as 'famous UK landmarks'. Groups search, list three sources, and rate reliability using a checklist for date, author, and images. Present ratings and vote on best source.

Evaluate the trade-offs of using short versus long search terms.

Facilitation Tip

In the Reliability Hunt, assign each group one website feature to investigate, so all aspects of trustworthiness are covered across the class.

What to look for

Give each student a card with a website address. Ask them to write one sentence explaining one reason why this website might be a reliable or unreliable source of information. Collect these to gauge understanding of source evaluation.

Activity 03

• 20 min · Whole Class

Whole Class: Live Search Demo

Project a search engine. Class brainstorms a query together, like 'Year 3 computing games'. Enter it, analyse top results as a group, then vote on refinements and re-search to compare improvements.

Differentiate between reliable and unreliable information sources found online.

Facilitation Tip

During the Live Search Demo, pause after each search to ask pupils to predict what the next result will look like and why.

What to look for

Ask students: 'Imagine you searched for 'dogs' and got millions of results. What are three specific words you could add to your search to find out about 'golden retriever puppies' instead? Why do these words help?' Facilitate a brief class discussion on query refinement.

Activity 04

• Outdoor Investigation Session
• 30 min · Individual

Individual: Search Journal

Pupils choose a personal interest, log initial search, results, and two refinements with screenshots or notes. Reflect on what made searches better. Share one success in plenary.

Analyze how a search engine prioritizes results for a given query.

Facilitation Tip

Have pupils annotate their Search Journals with the date and time of searches to connect recency to result differences.

What to look for

Present students with a simple research question, like 'What is the tallest building in London?'. Ask them to write down two different search queries they would use to find the answer. Then, have them explain which query they think will give a better result and why.

A few notes on teaching this unit

Teachers should model imprecise versus precise queries aloud, thinking through the process together. Avoid over-explaining algorithms; instead, let pupils discover patterns through guided trials. Research shows hands-on practice with immediate feedback builds stronger understanding than lectures on how search engines work.

By the end of these activities, pupils will confidently choose precise keywords, use operators to refine searches, and begin assessing result reliability. They will articulate why vague queries fail and how algorithms shape what they see online.

Watch Out for These Misconceptions

• During Pairs Challenge, watch for pupils who assume any match means a good result.

  Have pairs swap their refined queries with another pair and test them, then compare which query returned more relevant results and why.

• During Reliability Hunt, watch for pupils who equate visual appeal with accuracy.

  Direct groups to rate websites based on specific criteria, such as presence of author names or publication dates, and present counterexamples like a well-designed but outdated page.

• During Live Search Demo, watch for pupils who think the first result is always correct.

  Run a quick search for a topic with conflicting information, like 'Is Pluto a planet?' and have pupils identify which results support each side before discussing bias.
