analyse and evaluate sources and/or processes to support research, arguments and perspectives

📚 Research, Analysis & Evaluation – IGCSE Global Perspectives 0457

1️⃣ Introduction

In Global Perspectives you’ll often need to gather information, look at it closely, and decide if it’s trustworthy. Think of it like being a detective 🕵️‍♂️: you collect clues, examine them, and decide which story fits best.

2️⃣ Types of Sources

• 📖 Primary sources – original evidence (e.g., a diary entry, a photo, a speech).
• 📚 Secondary sources – analysis or interpretation of primary sources (e.g., a history book, a news article).
• 🗞️ Tertiary sources – summaries of primary and secondary sources (e.g., encyclopedias, databases).

3️⃣ Evaluating Sources – The 5 C’s

Use these criteria to judge each source:

4️⃣ Analyzing Data & Arguments

Once you have trustworthy sources, break them down:

1. 🔍 Identify the main claim or thesis.
2. 📊 Look at the evidence – facts, statistics, quotes.
3. 🧩 Check the logic – does the evidence support the claim? Are there gaps?
4. 🤔 Consider counter‑arguments – what could someone else say?

5️⃣ Evaluating Processes

Research isn’t just about sources; it’s also about how you gather and use them.

• 🗂️ Search strategy – use specific keywords, Boolean operators (AND, OR, NOT).
• 📑 Note‑taking – keep track of where each piece of info came from.
• 🔄 Review & revise – revisit earlier steps if new evidence emerges.

6️⃣ Case Study: Climate Change Debate

Let’s walk through a quick example.

1. 🔎 Source 1: A peer‑reviewed journal article (primary). Credible, accurate, recent.
2. 📚 Source 2: A popular science magazine (secondary). Good coverage, but check for sensationalism.
3. 🗞️ Source 3: An encyclopedia entry (tertiary). Great for quick facts, but less depth.
4. 🧠 Analysis: The journal article provides hard data (e.g., temperature rise $ΔT = 1.2^\circ$C since 1850). The magazine adds real‑world stories, while the encyclopedia confirms the trend.
5. 🧐 Evaluation: Combine the strengths: use the data for arguments, stories for impact, and the encyclopedia for quick checks.

7️⃣ Key Takeaways

• 🔑 Treat every source like a puzzle piece – it must fit with the rest.
• 🛠️ Use the 5 C’s to test credibility.
• 📈 Analyse evidence, logic, and counter‑arguments before forming a conclusion.
• 🔄 Keep your research process flexible; new info can change your view.
• 💡 Remember: the goal is to build a solid, well‑supported argument that others can trust.
