Required resources: I authored a lecture outline that serves as the script for the videos. The lecture outline is entitled “Biology: The Fabric of Life (Biology 100/101) Lecture Outline and Study Guide.” I wrote it, I lectured from it in the videos, and I used it to prepare the course assignments and exams. You must have the lecture outline to be successful in the class. Because the lecture outline (and video series) contains graphics from Pearson Publishing, I am required to post the lecture outline on a Pearson Publishing Blackboard website called Course Compass. You must purchase access to Course Compass.
So, to access the lecture outline you must purchase the text for the course, or access to the publisher’s website, called Course Compass. Course Compass is a Blackboard webpage for the class hosted by the publisher. When you go to the bookstore or look online you have these choices:
If you choose the $98.75 option, you will get a password to access to Course Compass; and a hard copy of a college level textbook (Biology: Concepts and Connections) with ebook access.
If you choose the $30.00 option you will only get the access code to Course Compass, which in turn gets you to the lecture outline.
To register you need to provide the following information in addition to the Course Compass Access Code: Course ID = sourbeer84754; Palomar College zip code = 92069. You will also be asked to submit a password of your own: be aware that the password you submit must be a minimum of 8 characters, and at least one of the characters must be a number.
