The author shows that the set of all sequences in which each term is the sum of the two previous terms forms a vector space of dimension two. He uses this result to obtain the formula for the Fibonacci sequence and applies the same technique to other linear recursive relations. (MM)

Evaluated were measures of mathematical ability of college freshmen for effectiveness of predicting performance in a televised pre-calculus course. A Two-stage sequential selection model is developed which yields gains in predictability over other models. (JG)

The author suggests that a close analysis of existing calculus courses indicates that some of the material can be explained much more clearly by using some of the language of set theory. He gives examples showing that many of the pedagogical problems arising in calculus can be overcome by using a graphical approach. (FL)

A method for introducing ideas of probability theory is presented. The method is illustrated by solving a coin tossing" problem. (FL)
