Investigating OER on the Web: How to Find Quality Open Educational Resources

Open Educational Resources (OER) have transformed the way educators teach and learners engage with content. These free, openly licensed materials are available online and designed to be reused, remixed, revised, and redistributed. But with thousands of websites claiming to offer OER, how do you know where to look—and how to choose the right resources?

This guide focuses on investigating OER on the web, helping educators and students find high-quality, trustworthy, and legally sharable content for their learning needs.

Where to Find OER Online

Several reputable platforms host curated OER collections. When exploring OER on the web, prioritize well-established repositories that offer diverse formats—such as textbooks, quizzes, lesson plans, videos, and interactive tools.

Here are some top OER websites:

  • OER Commons – Offers resources across all educational levels with built-in tools for evaluation and remixing.
  • OpenStax – Provides peer-reviewed, high-quality open textbooks in college subjects.
  • MERLOT – A multidisciplinary platform with user ratings and peer reviews.
  • Open Textbook Library – Features free textbooks vetted for quality and effectiveness.

  • SkillsCommons – Offers workforce development and career training OER.

Evaluating OER: What to Look For

When investigating OER on the web, don’t just grab the first result you find. Instead, evaluate each resource using these key criteria:

  • Relevance: Does it match your learning objectives or curriculum standards?
  • Accuracy: Is the information factually correct and up to date?
  • Quality: Is the content well-organized, visually clear, and professionally written?
  • License: Is it truly open? Look for a clear Creative Commons license (e.g., CC BY or CC BY-SA).
  • Accessibility: Can students with disabilities use the material easily?
  • Adaptability: Can you modify the resource to meet local needs?

Most OER platforms include metadata and licensing information to guide your decision.

Tools and Tips for Searching

To streamline your search for OER:

  • Use advanced search tools in Google by selecting usage rights like “free to use, share, or modify.”
  • Use OASIS (Openly Available Sources Integrated Search) at https://oasis.geneseo.edu to search across multiple OER databases at once.
  • Check for curriculum alignment tags or user feedback to determine educational suitability.

Conclusion

Investigating OER on the web requires more than a simple search—it demands critical evaluation, platform awareness, and license literacy. By knowing where to look and how to assess the content, educators and learners can unlock a world of free, flexible, and high-impact educational materials that enhance both teaching and learning.
