Reported are three studies which have been completed since the inception of a collaboration between the Inglewood Schools and UICSM. These include a comparison by a matched-pairs design, a total group comparison in which covariance analysis provided statistical control, and an item analysis of the tests which obtained difficulty indices for the…

This is the first of a two-part paper; the conclusion appears in volume 27, number 3 (SE 506 350). (JM)

An overview of classical mathematics and of modern mathematics is given, with implications noted for secondary school curriculum and instruction. (DT)

Why calculus is taught in secondary schools is discussed, as well as how "modern mathematics" affected calculus, is calculus so difficult, and how calculus should be taught. (MNS)

Discussed are possible lessons for teaching the algebraic concepts of variables, rational expressions, and functions. (CT)

The authors present an enrichment topic appropriate for use in grade 12. A mathematical system is defined using integer 3-tuples and it is shown that this system is a field isomorphic to the rational numbers. The unit is useful for illustrating the abstract nature of mathematics. (CT)
