Lesson Plan

• Describe the components of claims, arguments, and perspectives.
• Evaluate different types of evidence for credibility, relevance, bias, currency, and sufficiency.
• Analyse reasoning for logical consistency and identify common fallacies.
• Compare alternative perspectives and assess cultural, ethical, and economic influences.
• Apply a systematic research process to draw evidence‑based conclusions on a global issue.

• Projector and screen
• Whiteboard and markers
• Printed handouts: evidence‑evaluation checklist & case‑study worksheet
• Laptops/tablets for online source search
• Sticky notes and rubric cards for peer feedback

Begin with a striking image of plastic debris in the ocean and ask students to imagine a world without it. Review prior knowledge of what a claim, argument, and perspective are. Explain that by the end of the lesson they will be able to evaluate evidence and construct a well‑supported argument, which will be the success criteria for today.

1. Do‑now (5'): Students write a claim about a global issue on sticky notes (checks prior knowledge).
2. Mini‑lecture (10'): Define claim, argument, perspective; introduce types of evidence.
3. Group analysis (15'): Using the plastic‑pollution case study, evaluate each source with the checklist (credibility, relevance, bias, etc.).
4. Reasoning workshop (10'): Identify logical fallacies and assess the strength of the arguments.
5. Perspective debate (10'): Groups present alternative viewpoints and discuss cultural/economic biases.
6. Exit ticket (5'): Write one evidence‑based conclusion and a self‑assessment of the evaluation process.

Recap the five‑step evaluation process and highlight how each step strengthened the final conclusion. Collect exit tickets as a quick retrieval check. For homework, students select a new claim, gather at least three sources, and complete the evaluation worksheet to prepare for the next lesson’s argument‑building activity.
