This year, the molecular and cellular foundational class, Principles of Living Systems, is going to be textbook free. The pre-class assignments will be from the Khan Academy.
Some students will like the change, others will be leery of not being able to have and to hold a textbook. If you’re taking my course and you feel the need to have a textbook, I have a perfectly free idea for you! OpenStax is an organization that produces high-quality textbooks that can be downloaded for free.
There are two Biology textbook options at OpenStax.
