Do open educational resources improve student learning? Implications of the access hypothesis.

Area of Science:

• Educational Technology
• Higher Education Research
• Open Educational Resources (OER)

Background:

• Open Educational Resources (OER) are recognized for reducing student costs and enhancing equity in higher education.
• Existing research on the learning benefits of OER has yielded mixed results, with many studies reporting null effects.
• The efficacy of OER in improving student learning outcomes remains a significant question in educational research.

Purpose of the Study:

• To investigate why current research methods may fail to detect the learning benefits of Open Educational Resources.
• To evaluate the predictions of the access hypothesis regarding OER's impact on student learning.
• To propose that standard methodologies are insufficient for identifying OER's true educational value.

Main Methods:

• The study employs simulation analysis to model the detection of OER learning effects.
• It examines the limitations of common research methodologies in the context of the access hypothesis.
• The analysis focuses on whether existing methods can identify benefits for students with limited access to course materials.

Main Results:

• Simulation analysis indicates that standard research methods are unlikely to detect positive learning effects from OER.
• This limitation persists even when a genuine learning benefit from OER exists.
• The findings suggest a methodological barrier to confirming OER's positive impact on student learning.

Conclusions:

• Current research practices may systematically underestimate the learning benefits of Open Educational Resources.
• The access hypothesis suggests OER's benefits are conditional on student access, a factor often overlooked by standard methods.
• Further research should explore alternative methodologies to accurately assess the learning impact of OER in higher education.
