Query: Rates at an 11th grade reading level... for a 7th grade textbook!!

I am currently a college student in a class on reading in the content areas. In our class, we recently completed a textbook readability survey for this book (as well as several others) using the "Fry Readability Model." This model measures reading difficulty based on word syllables and sentence length. After evaluating three random passages in this book (from the beginning, middle, and end), this book rated at an 11th grade reading level. It was easily the largest disparity of all the books my class rated.I just wanted to post this information because I found it to be very interesting, in a negative way (of course). If you are thinking of adopting this textbook for your class, please think twice. It is likely to be well over the heads of your average 7th grader.
