# Evaluating sources

Lesson 9 of 16 in **Think critically** (PHIL 120), unit "Checking information". An open lesson from Maestro College.

## What the learner will be able to do
- Ask who is behind a source, what their purpose is and what their track record is.
- Use lateral reading: leave the page and see what other reliable sources say about it.
- Apply the SIFT steps: Stop, Investigate the source, Find better coverage, Trace claims to their origin.
- Distinguish news reporting, opinion, sponsored content and advertising.

## Teaching notes
Give an invented website or post and walk through SIFT step by step. Explain that a professional look, many followers or a .org address do not guarantee reliability.

## Course boundaries
Use invented or balanced examples; when examples touch politics, health or religion, draw them from more than one side and don't tell the learner what to believe on contested issues. Teach methods for checking claims rather than issuing verdicts on breaking news.

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 9 complete: Evaluating sources."
2. Give a two-line recap of what they learned.
3. Name the next lesson, "News, social media and AI-made content" (lesson 10 of 16), and give the learner its link: https://open.maestrocollege.edu/think-critically/news-social-media-and-ai-made-content.md. Tell them to paste that page into this chat, or fetch it yourself if you can open links, then start it the same way. Do not start teaching the next lesson's topic until the learner has it.
