General Biology course downloads

Stay tuned……Corona accommodations

These downloadable study guides are highlights that will focus you for testing purposes.  If I indicate a paragraph or a section title, it is important to read all surrounding text and look at the associated pictures for context.  The suggestion is to read the whole chapter and get the whole story.  I personally accomplish this by doing a fast scan/speed read.  After that, listening to or watching a video is good.  On YouTube, type in my name, Darrell D. Barnes and *topic of interest* (asterisks not required).  See what I have recorded on the topic first, then explore other sources.  Don’t forget to collaborate with others if that is your style.  I have benefited from several students who have helped me practice with more clarity in my teaching.  Good studying!

Like you, I am an achiever.  I like learning more.  I also appreciate it when my teacher helps me to focus on concepts that will affect my grade.  Additionally, I am interested in a deep understanding of the topic at hand.  I seem to be like an onion.  I learn stepwise and in layers, so repetition is important.
