Truly awful. Don't waste your time.
on October 27, 2012
First, full disclosure -- My review is based on the first lesson only -- I put this ebook down after one "lesson" it was so bad... The page layout is clean and that gives a (false) impression of competence but after only a few pages it becomes obvious that this book is complete crap. I honestly wonder on what the positive reviewers could have based their opinions; they can't have been working carefully. I once made my living writing and editing exactly this kind of educational material (and no I'm not selling my antiquated work in this review) -- I'm saying I'm professionally familiar with this kind of teaching text. I've seen material this dreadful published before and rather than bore you with my theories of why, how and by whom this stuff gets made, let me just say: I know that when a first lesson contains gross errors in fact and fails at the most basic levels of organization you can be sure the rest of the text isn't going to miraculously improve.
For example: a main topic of the first lesson is Venn diagramming. The text does not merely fail to teach Venn diagramming, it actually fails to correctly solve its own problems! I don't mean typos. The author evidently does not understand what she purports to teach. The text gives data about students taking chemistry, science & math tests to illustrate Venn diagramming intersecting sets.Then... the data is diagrammed incorrectly. I mean it's just wrong. (And, FYI, to illustrate the editorial shortcomings of this book: -- this intersecting sets problem is given (twice) under the absurd and nonsensical heading "Bias and Probability" which is also given twice!)
There are other errors and absurdities in the lesson every bit as grotesque as this. In the first lesson! (Like I said... I stopped) But if this error doesn't convince you -- well, you can't say you weren't warned.
If you are curious to see if this book is really as bad as I claim there are good free sites that teach how to Venn Diagram just a google search away. (It's not particularly difficult.) Learn Venn Diagramming and then check out this free ebook and determine for yourself if material in the first chapter here holds up. Personally, I recommend saving your time and just finding a better text.
