What Do You Want to Learn?

As part of our commitment to affordable learning, we make free, public reference versions of all TEL Library lessons available to everyone, everywhere.

Lesson Features

Each of our lessons is designed as self-contained learning environment that provides all the context, explanation, and resources you need to learn about a specific topic. We give you the information you need in a format that helps you apply it in your daily life.


Knowing why a topic matters and and how it applies to your experience is an important part of learning anything. That’s why we make sure you have the proper context for the information we give you.

Video Overview

Every TEL Library lesson feature a video overview of the information being presented. Our videos provide helpful text callouts and a downloadable transcript.


We provide two different readings that elaborate information related to the lesson topic. The first gives you essential, objective information while the second offers a deeper look at a specific sub-topic or a view of different perspectives.


Developing a clear understanding of a topic generally requires that you spend time reflecting on the meaning or impact of its concepts and information. We facilitate this reflection with polls designed to help you create connections to the topic.



It’s easy to get tripped up on unfamiliar terms when you’re trying to learn something new. We’ve developed in-line glossary definitions of key terms to help make lessons easier to read and understand.

Toolbox Resources

We know that our lessons are simply a starting point for many learners. That’s why we provide a toolbox with related web resources for each lesson so that you can continue your learning journey on a specific topic.
