How Open Educational Resources Are Transforming Science Learning
Explore the TransformationOpen Access • Customizable • Cost-Free
Imagine a student, eager to learn chemistry, faced with a daunting choice: pay hundreds of dollars for a required textbook or try to succeed without it.
The rising cost of educational materials creates a significant barrier to science education, preventing many students from accessing quality learning resources.
Open Educational Resources (OER) are freely accessible, openly licensed materials that are revolutionizing how chemistry is taught and learned.
By removing price barriers and enabling customized learning experiences, OER are opening doors to scientific literacy and empowering a new generation of chemists. Let's explore how these innovative resources make chemistry more accessible, engaging, and equitable for everyone.
Open Educational Resources (OER) are teaching, learning, and research materials that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation, and redistribution.

| Benefit | Impact on Chemistry Learning |
|---|---|
| Cost Savings | Eliminates textbook costs, ensuring all students have access to materials from day one |
| Accessibility | Can be adapted for different learning needs and accessed across multiple devices |
| Current Content | Rapid updates possible to include latest discoveries and methodologies |
| Pedagogical Flexibility | Instructors can tailor content to specific course contexts and learning objectives |
| Student Success | Research shows comparable or better outcomes and lower withdrawal rates 4 |
The most significant advantage of OER extends beyond cost savings. A study examining OER through an equity, diversity, and inclusion lens found that these resources can foster a greater sense of belonging for students, particularly when they include diverse representation and inclusive language 4 . This is especially important in STEM fields like chemistry, where diverse perspectives drive innovation.
To understand how OER work in practice, let's examine a common experiment found in many OER chemistry lab manuals: "The Density of Liquids and Solids."
This experiment teaches fundamental measurement techniques and data analysis skills essential for all chemical sciences.
Objective: To determine the density of pure water and aluminum, then use these values to calculate the thickness of aluminum foil.
The procedure, adapted from the LibreTexts Chem 10 Experiments manual, demonstrates how OER provide clear, replicable laboratory instructions 7 :
This experiment teaches students about instrument precision, measurement uncertainty, and quantitative analysis—all core chemical concepts. Students learn that all measuring devices have inherent limitations, and they practice accounting for these limitations in their calculations 7 .
The water displacement method for determining aluminum's volume demonstrates Archimedes' principle in action, while the aluminum foil activity shows how chemists work backward from known properties (density) to determine unknown parameters (thickness). This mirrors real-world chemical analysis where scientists must often develop indirect methods of measurement.
| Material | Mass (g) | Volume (mL or cm³) | Calculated Density (g/cm³) | Percent Error (%) |
|---|---|---|---|---|
| Distilled Water | 24.95 | 25.00 | 0.998 | 0.2 |
| Aluminum Sample 1 | 18.45 | 6.82 | 2.71 | 0.4 |
| Aluminum Sample 2 | 22.10 | 8.16 | 2.71 | 0.4 |
Navigating the world of OER requires knowing where to find quality materials. Here are essential "research reagent solutions" for your chemistry learning journey:
| Resource | Function | Example Platforms |
|---|---|---|
| Comprehensive Textbooks | Provide foundational knowledge with interactive elements | OpenStax Chemistry, LibreTexts, SUNY OER Services 3 8 |
| Virtual Labs & Simulations | Allow safe, cost-effective experimentation and visualization | PhET Interactive Simulations, ChemCollective Virtual Labs 3 |
| Laboratory Manuals | Offer standardized experimental procedures and safety guidelines | SUNY OER Chemistry I Laboratory Manual, MIT Digital Lab Techniques Manual 3 7 |
| Courseware & Lesson Plans | Provide complete learning sequences with assessments | Carnegie Mellon OLI General Chemistry, MIT OpenCourseWare 3 |
These resources represent just a fraction of the available OER for chemistry. The key advantage is that instructors can mix and match elements from different sources to create a customized learning experience that addresses specific course objectives and student needs.
The traditional textbook model doesn't just create financial barriers—it can also create conceptual barriers when materials don't reflect diverse perspectives and learning styles.

Research shows that OER can particularly benefit underserved student populations, including Pell Grant recipients and underrepresented minority students, who often struggle most with textbook costs 4 .
OER support inclusive teaching practices by allowing instructors to incorporate diverse examples and scientific contributions from chemists of various backgrounds.
Educators can adapt content to match student interests and local contexts, providing multiple representation formats to address different learning preferences.
OER ensure accessibility for students with disabilities through adaptable formats, making chemistry education more welcoming for all learners.
As one study noted, "OER can foster greater equity, diversity, and inclusion by promoting use and access of the materials, better diversity of representation within the content of the materials, and more inclusive teaching strategies" 4 . This transformative potential makes OER particularly valuable for making chemistry education more welcoming and effective for all learners.
Ready to explore OER for your chemistry studies or teaching? Here's how to get started:
| Platform | Key Features | Notable Chemistry Resources |
|---|---|---|
| LibreTexts | Multi-institutional collaboration, constantly updated | Chemistry Library, Chem 10 Experiments, Adaptable Textmaps 3 7 |
| OpenStax | Peer-reviewed, high-quality textbooks | Chemistry, Chemistry: Atoms First (also available as smartphone/tablet apps) 3 |
| OER Commons | Large collection, filtering options | Over 2,200 chemistry resources, including labs and activities 8 |
| PhET Simulations | Interactive, game-like environment | Molecular shape simulator, reactions & rates, concentration visualization 3 |
Open Educational Resources represent more than just an alternative to expensive textbooks—they embody a shift toward more accessible, adaptable, and student-centered chemistry education.
Eliminating cost barriers for all students
Customizable to diverse learning needs
Empowering learners through open access
By eliminating cost barriers and empowering educators to tailor materials to their students' needs, OER are helping to democratize chemical knowledge. From interactive simulations that bring molecular interactions to life to customizable textbooks that reflect diverse scientific contributions, these resources are expanding what's possible in the chemistry classroom.
As the OER ecosystem continues to grow and evolve, its potential to transform chemistry education grows with it. The next breakthrough in chemistry might come from a student who entered the field precisely because OER made chemical education accessible. In making chemistry open to all, we're not just saving money—we're investing in a more innovative, inclusive, and scientifically literate future.
