Search in 2026 is really two tools sitting side by side. Traditional keyword search (Google, Bing, DuckDuckGo) hands you a ranked list of links, while AI search (Perplexity, ChatGPT search, Claude, Gemini) writes you an answer and cites its sources. Being fluent in both, and knowing when each lets you down, is exactly the skill your Module 4 investigation needs.
Think about the last time you searched for something and got a wall of useless results. Did you change your words and try again, or did you give up? What would have helped you find the right thing faster?
Open with the two-tools framing on the board: traditional search returns links, AI search returns a written answer with sources. Ask the class who has used an AI tool for a question this week — most hands go up. Name the risk early: AI confidently makes things up, so verification is the student's job.
This lesson directly scaffolds the SM4 KA1 investigation and feeds the Contemporary Issue Task and General Education Task. Note that the written General theory exam section tests traditional operators explicitly, so those must be learned, not just skimmed.
Put one shared example topic on the board so no student is blocked at the first operator step. Suggested fallback: apprenticeship pay in Ireland.
Today's lesson works in two worlds. Traditional search rewards precise keywords and operators; AI search rewards clear questions and follow-ups. The one rule that spans both: you own the truth of your findings, so anything an AI tells you must be checked against a source you can open.
| Concept | Why it matters | Example |
|---|---|---|
Site operator — site: restricts results to one website or domain | Cuts out unreliable noise when you only trust one source type for your investigation | apprenticeship pay site:gov.ie returns only official Irish government pages on apprenticeship pay |
Filetype operator — filetype: limits results to one file format | Official reports and datasets are often PDFs, so this finds the primary document not a news summary of it | youth employment filetype:pdf site:cso.ie finds CSO PDF reports directly |
| Exact-phrase quotes — wrapping words in " " forces an exact match | Stops the engine from scattering your words across unrelated pages | Searching "digital age of consent" Ireland keeps the phrase together |
Exclusion operator — a minus sign - in front of a word removes results containing it | Clears out a common but unwanted meaning that keeps polluting your results | apprenticeship pay -jobs drops job-advert pages so you see the pay information itself |
OR operator — the word OR in capitals returns pages matching either term | Catches both ways a topic might be worded so you don't miss good sources | apprentice OR trainee pay Ireland returns pages using either word |
| AI search prompt — a clear question you ask an AI tool, then follow up on | Good for a fast overview and for finding starting sources you then verify | Asking Perplexity "What is the standard VAT rate in Ireland and give me your sources" returns an answer plus links to check |
| Verification — opening at least one cited source before trusting an AI answer | AI hallucinates confidently; an unchecked answer can be completely wrong in your KA evidence | An AI names a statistic; you open its cited link and find the figure is actually different — you catch the error before it reaches your investigation |
For search you use the AI as an Explainer: you ask it to explain a topic and point you at sources you can open and check for yourself.
Demonstrate two operators and one AI prompt live on the classroom screen so students see the difference before they try it. Stress the verification concept — search the class for an AI answer, then open its cited source together and check whether it holds up. This is the exam-relevant and KA-relevant habit.
The General theory written exam section tests traditional operators, so make sure site:, filetype:, exact-phrase quotes, exclusion (-) and OR land clearly for every student.
Work through a short comparison: run the same information need several ways using traditional operators, then run it through an AI search tool and check its sources. You'll build your reusable cheatsheet as you go. If you haven't picked your investigation topic yet, use apprenticeship pay in Ireland for this task.
Circulate during this segment. The most common stumble is students typing the operator with a space after the colon (site: gov.ie) which breaks it — watch for that. Run a quick checkpoint after the operators + table block (instruction 8) before students move on to the AI prompt and verification, so weaker readers don't fall behind. If the school uses one specific browser or AI tool, point students at the approved one during the demo. On a touch device, students long-press or double-tap in the search box to get straight double quotes and should turn off any autocorrect that inserts a space after the colon.
| Issue | Solution |
|---|---|
| My operator returns no results at all | Check there is no space after the colon — it must be {{code:site:gov.ie}} not {{code:site: gov.ie}}. Also try a broader domain like .ie if the specific site has nothing. |
| My OR operator didn't work | OR must be in capital letters. Lowercase 'or' is treated as an ordinary word, not an operator. |
| The AI didn't give me any sources | Ask again and explicitly add "list your sources with links". Some tools only cite when you ask directly. If it still won't, treat everything it says as unverified. |
| The link the AI cited doesn't exist or won't open | This is a hallucinated source. Do not use the AI's claim. Search the fact yourself using traditional operators to find a real source. |
| My exact-phrase quotes still return loose results | Make sure you used straight double quotes " " not curly quotes. Retype the quotes directly in the search box. |
The hallucinated-source issue is the most important one for the exam and the KA. If a student hits a dead cited link, use it as a teaching moment for the whole class — this is exactly why verification is non-negotiable.
This artifact feeds the SM4 KA1 investigation directly — the operators students choose here are the ones they'll reuse when gathering their real sources. It must be started and verified in class, not deferred to homework, because it is the KA evidence. Confident and fast students can add the remaining operators and a third AI prompt as bonus rows. Encourage honesty in the verification notes; a note that says "the AI got it wrong" is more valuable evidence of the skill than one that says everything checked out.
