I'd certainly award them to Mr. Selby and Dr. Slavin's book. I'm not finished with the text, but I'm learning so well that I KNOW I will have mastered the material. In fact, I just ordered the book which they recommend as a follow-up, "Geometry and Trigonometry for Calculus." They start out with baby steps -- literally simple addition and subtraction, and work up to fairly sophisticated algebraic expressions and problems. The student finds himself enjoying the material almost like it were a novel. Selby and Slavin give immediate answers for ALL the problems, so there's no frustration wondering if the problem is solved correctly. If the student misses a certain number of problems in a set, the authors recommend review of specific "frames" which cover the material. They treat the student with respect, making it clear that NO ONE (least of all someone who is motivated to study through their text) is a dummy. This is so much easier than trying to keep up with a math teacher who scribbles and then erases the material on a blackboard about as fast as he/she can write. I now know that self-paced learning is the way to go, at least for me. Many years ago, I failed calculus in college, and barely squeaked through college algebra and trigonometry. I fully intend to use this framework as a basis to repeat the course (even if via correspondence) and get this only blotch on an otherwise fine college career off my record. How sad that Mr. Selby has passed on, but how great it is that his books live still.
