foabbot, February 28, 2007

We used this text in a precalculus class that I recently finished. This book covers a lot of material so success using this book will depend on the teacher. There were some people who thought it was an unwieldy text; there are plenty of review exercises that would be worth spending the time but you would benefit most if you could see how they were done to arrive at the correct answers. In the introduction, the authors say that: 1)many problems are open-ended, meaning there is more than one correct approach to solving them 2)there are few examples in the text that are exactly like the homework problems 3) they recommend group work and discussions.
I can tell you there are not enough hours in the classroom to make group discussions and team efforts at problem-solving work. I am taking a class now that uses team efforts to solve problems and it works (sort of, and success is uneven) because most of the problem-solving is done, graded and recorded by a computer program.
We did try to work in groups using this precalculus text. However, as I said, speeding along to try to cover the necessary material (in order to take calculus), there just isn't enough time.
What the authors did say was true: if you put in a solid effort, you will get a real understanding of functions. I used several other texts to supplement this text (I found trigonometry to be especially difficult but that is just me) and studied my a** off. I did well in the course and will probably refer to this book in the future.
