Today’s classrooms bring together students with widely varying levels of preparation, language backgrounds, and confidence in laboratory settings. Adjusting every course to accommodate that variation can be challenging, but thoughtful use of teaching materials can make learning more consistent, effective, and inclusive for everyone.
The Universal Design for Learning (UDL)¹ framework offers a research-based way to make lessons more accessible without starting over. Its three principles—Engagement, Representation, and Action & Expression—help educators design flexible pathways into complex material.
Video-based instruction aligns closely with these ideas, helping students see, hear, and practice scientific methods in ways that strengthen understanding and skill development.
