A method for solving inequalities of degree greater than one is described. (MK)

The author describes a method for introducing mathematical induction employing Fibonacci numbers. (MK)

A seemingly paradoxical situation is explained which tells of one baseball player having a higher batting average than a second player for two seasons, yet having a lower overall average. (MP)

A proof is given of a construction axiom, involving the use of a Mira used to construct a segment of a length cube root of K when segments of lengths 1 and k are given. (MP)

Student errors led to this exploration of the conditions under which log of x base a = x. The discussion requires only techniques contained in a first-year calculus course. (MP)

Features of one particular kind of map, called a polar stereographic projection, are discussed in detail. (DT)

Partial converses are considered of the theorem stating that in an isosceles triangle, the bisector of the apex angle, the altitude to the base, and the median to the base all coincide. (DT)

Discusses the formation of a geometry club in which members (students, teachers, staff) of a high school meet in order to discuss and demonstrate the mathematics in Euclid's Elements. (MKR)

Discusses two six-week projects for high school students involving qualitative and quantitative research methods to integrate mathematics and English. Students use descriptive statistics and prose to present findings about (1) their school space and (2) daily life for American troops in the Gulf War. (KMC)

Describes an activity in which students deal a deck of cards to 5, then 4, then 3, then 2 players; note the number of cards left over each time; and from this information determine the number of cards in the deck. (MKR)

Compares observed to expected counts of white, African American, and Hispanic major-league baseball players (n=650) in 1989. Uses chi-square values to determine that racial differences are highly significant for pitcher, catcher, shortstop, and outfielder. Includes appendix with 1993 player counts and seven suggested student activities. (SEW)

Discusses the importance of calculators in the teaching and learning of mathematics. Argues that affordable graphing calculators let all mathematics students use computer visualization on a regular basis for both in-class and out-of-class activities. (ASK)

Explores a workable definition of mathematical structure and a rationale for teaching mathematical structure in the secondary school. Continues with mathematical structure appropriate for secondary mathematics teachers and suggestions for teaching mathematical structure in the secondary school. Contains 11 references. (ASK)

Describes the systemic reform necessary to bring about the requisite changes that reflect those recommended by the National Council of Teachers of Mathematics (NCTM). Among the characteristics of systemic professional development are a long-term collaborative plan focused on the total learning community with its construction by its participants.…

Presents requisites for and characteristics of reform, identifies sources of problems teachers face when implementing change, and gives tips for success. (KHR)
