Research Skills and Source Evaluation Guide

In today's information-rich world, the ability to find, evaluate, and synthesize credible sources is perhaps the most crucial skill for academic success. For IB students working on Extended Essays, Internal Assessments, and research-based assignments, mastering research skills and source evaluation determines not just the quality of your work, but also your ability to think critically about the world around you.

Understanding the Information Landscape

Before diving into research strategies, it's essential to understand the modern information environment and its challenges:

Information Abundance vs. Quality

• Volume: Millions of sources available on any topic
• Accessibility: Instant access to global information
• Quality variation: Wide range from expert analysis to misinformation
• Context collapse: Information removed from original context

Types of Information Sources

Primary Sources

• Definition: Original materials created during the time period or by direct participants
• Examples: Historical documents, research studies, interviews, surveys, artifacts
• Strengths: First-hand evidence, unfiltered information, unique insights
• Limitations: May lack context, require interpretation, potentially biased

Secondary Sources

• Definition: Materials that analyze, interpret, or comment on primary sources
• Examples: Scholarly articles, textbooks, documentaries, critical essays
• Strengths: Provide context, expert analysis, synthesize multiple sources
• Limitations: Removed from original events, potential for bias, interpretation varies

Tertiary Sources

• Definition: Sources that compile and summarize primary and secondary sources
• Examples: Encyclopedias, handbooks, guidebooks, some websites
• Strengths: Good starting points, broad overviews, accessible language
• Limitations: Simplified information, lack depth, may be outdated

The CRAAP Test for Source Evaluation

Use the CRAAP test (Currency, Relevance, Authority, Accuracy, Purpose) as a systematic approach to evaluating sources:

Currency: Is the Information Current?

• Publication date: When was the source created or last updated?
• Relevance of timing: Is currency important for your topic?
• Information updates: Has the information been revised or updated?
• Link functionality: For websites, do links work and lead to current information?

Questions to Ask:

• When was the information published or posted?
• Has the information been revised or updated?
• Is your topic one where information changes quickly?
• Are there more recent sources that might be better?

Relevance: Does the Information Meet Your Needs?

• Topic alignment: Does the source address your research question?
• Scope appropriateness: Is the information too basic or too advanced?
• Geographic relevance: Is the geographical focus appropriate?
• Audience match: Is the source written for your intended audience?

Questions to Ask:

• Does the information relate to your topic or answer your research question?
• Who is the intended audience?
• Is the information at an appropriate level for your needs?
• Would you be comfortable using this source in your assignment?

Authority: Who is the Source of Information?

• Author credentials: What are the author's qualifications?
• Institutional affiliation: What organization is the author associated with?
• Publication reputation: Is the publisher or platform reputable?
• Contact information: Is there a way to verify or contact the author?

Questions to Ask:

• Who is the author/creator of the information?
• What are the author's credentials or organizational affiliations?
• Is the publisher reputable?
• Does the URL reveal anything about the source (.edu, .gov, .org, .com)?

Accuracy: How Reliable is the Information?

• Evidence provided: Are claims supported by evidence?
• Citation quality: Are sources properly cited and credible?
• Fact-checking: Can you verify information through other sources?
• Language and tone: Is the language objective and professional?

Questions to Ask:

• Where does the information come from?
• Is the information supported by evidence?
• Can you verify the information in another source?
• Does the language or tone seem biased?

Purpose: What is the Purpose of the Information?

• Author's intent: Why was this source created?
• Bias identification: Does the author have a particular agenda?
• Commercial interests: Is the source trying to sell something?
• Objectivity: Is the information presented fairly?

Questions to Ask:

• What is the purpose of the information? To inform, teach, sell, entertain, or persuade?
• Do the authors/sponsors make their intentions clear?
• Is the information fact, opinion, or propaganda?
• Are there political, ideological, cultural, religious, or institutional biases?

Advanced Source Evaluation Techniques

Lateral Reading

Instead of reading deeply into one source, open multiple browser tabs to verify information across sources:

• Cross-verification: Check claims against multiple independent sources
• Source investigation: Research the publication or organization
• Author verification: Look up the author's credentials and other work
• Fact-checking sites: Use established fact-checking organizations

Citation Chain Analysis

• Follow citations: Check the sources that your source cites
• Find citing sources: Use tools to find who has cited your source
• Evaluate citation patterns: Look for sources that are frequently cited
• Check for citation loops: Identify when sources cite each other repeatedly

Publication Analysis

• Peer review status: Is the journal or publication peer-reviewed?
• Editorial board: Who serves on the editorial board?
• Impact factor: How influential is the publication in its field?
• Publisher reputation: Is the publisher known for quality standards?

Research Strategy Development

Defining Your Research Question

A well-crafted research question guides effective source selection:

Characteristics of Good Research Questions
