Week 1 Session: Connected, but what do you understand?
Work through a fictional Wi-Fi explanation, preserve your responses, and distinguish what happened from what you can conclude about understanding.
22 February 2027
Purpose and preparation#
This self-guided activity applies Week 1’s lesson. Allow 20 minutes. All required information is below. Work alone or with a partner; no live network experiment, paid tool or AI account is required. The cases are fictional. You are examining evidence of understanding, not completing a technical certification or graded test.
If you already know networking, record that familiarity. Do not pretend the material is new. If you completed the slide exercises, reuse your saved answers.
1. Read the reference — 3 minutes#
Wi-Fi connects a device wirelessly to a local network. Reaching an external website also requires a working route beyond that network. A laptop can remain connected to home Wi-Fi when the onward internet connection is interrupted. A failed website load alone does not identify the fault.
This simplified reference draws on Microsoft’s Wi-Fi guidance and Cloudflare’s router introduction. You may keep it visible throughout. Books, search or AI are optional additional resources; record what you actually use.
2. Explain a situation — 4 minutes#
An internet-provider outage occurs while the router and its Wi-Fi access point remain powered on. Could a laptop still be connected to the home Wi-Fi?
Write two or three sentences explaining why. Preserve your original wording. Record whether you consulted the reference, another source, or a partner.
Compare after attempting the explanation
Yes. The local wireless connection could remain while the onward internet connection is interrupted. An explanation should distinguish those two parts. “Wi-Fi is different from the internet” alone names the distinction but does not show how it explains this situation.
3. Reason about a changed case — 5 minutes#
The laptop cannot load a website. At the same time, another device freshly loads that website on the same home Wi-Fi, with mobile data off.
Does this prove the laptop’s hardware is broken? Explain, then name one further observation that could help. Keep the same resources available and preserve the response before reading the comparison.
Compare the reasoning
No. The site is reachable through this home connection for at least one device at that time. The observation does not identify the laptop’s cause. A browser or configuration issue remains possible. Checking another browser could narrow the possibilities without proving a complete diagnosis.
The useful feature is the limit placed on the conclusion. Your answer need not use exactly these words or suggest exactly this check.
4. Examine the answer — 5 minutes#
Keep a short record:
| Field | What to write |
|---|---|
| Prior familiarity | What did you already know about this distinction? |
| Conditions | Which sources and assistance were available and used? |
| Original answers | Preserve both responses before correction. |
| Observation | What did you or your partner actually say or do? |
| Interpretation | What specific ability does the response support? |
| Alternative | Could copying, prior practice or learning during the task explain it? |
| Limit | What further claim would require more evidence? |
For example: “With the notes available, I explained why the second device’s success does not prove a hardware fault. This supports reasoning about the supplied case. It does not show that I could diagnose a real unfamiliar fault.”
Working alone, you cannot independently verify your own account of how you produced the answer. Working with a partner adds observation, not access to their thoughts. Neither arrangement makes the conclusion certain.
5. Finish with the examiner’s question — 3 minutes#
Write a follow-up you would ask next, and explain which uncertainty it addresses. Do not make it harder merely by adding jargon. A useful follow-up distinguishes possible explanations of the performance.
If the response is strong, record that. If it changes after feedback, preserve both versions. Improvement during questioning is different from evidence about what the person knew beforehand.
For the challenge to automatically removing references, read Clark and Chalmers (1998), “The Extended Mind,” §§1–3. Ask whether the source is part of the competence you intended to examine.
The spec
What you bring to the session. Written so a reader can tell whether it has been met without asking you.
- preserve the original explanation and record sources consulted
- answer a changed scenario and explain the reasoning
- distinguish an observation, interpretation and remaining uncertainty
