Explore Life (with CD-ROM and InfoTrac)
LOVE IT!!  I have four students that took biology with me last semester and they say hands down this is a better book.  Of course anything would be better than what they had before, but for most of them their grades have improved this semester.  All four struggle with biology, so I think the book does help.  Other students that I have asked this semester like the book and feel it is very readable.  It also has worked out well to use for both 101 and 102.  I am teaching 102 which covers ecosystems, evolution and diversity of organisms.  So, the chapters I am using are in the following order 1, 24, 25, 9, 10, 11, 12, 21, 13, and 14.  It is always risky to use chapters out of order, but it has worked with your book.
