Reports an investigation to determine whether Vector and Analytic Methods make appropriate topics for high school students. It is concluded that they are. (BR)

The notion that the area of an inscribed n-sided polygon approaches the area of a circle as n approaches infinity leads to some interesting limits involving trigonometric functions. (MP)

Several results are explored which stem from the theorem stating that the line joining the midpoints of two sides of a triangle is parallel to and one-half of the third side. (DT)

Six different methods for bisecting a line segment are illustrated and explained. (DT)

Presents a mathematics problem on probability and matrices placed in a context with insects. Provides an overview, prerequisites, materials needed, and worksheets. (ASK)

Interprets the philosophical concept of warrant in a mathematics education context and applies it to two central questions: (1) in what sense does mathematical proof warrant?; and (2) can there be warrants for mathematical knowledge other then deductive proofs? (Contains 36 references.) (Author/ASK)

Discusses new techniques and new approaches to gathering information about student learning. Describes a project entitled "Enhancing the Teacher's Role in Assessment" in which 36 teachers from 11 school districts learned about traditional and alternative assessment. (ASK)

Reconsiders the article 'The .999999 Controversy' by Ronald Selby featured in the Spring 1999 issue which tracks the responses of high school classes to a sequence of six arguments offered to them that .999999=1. Discusses mathematical proofs and the proof of this particular question. (ASK)

Persistence of Vision Raytracer (POV-Ray), a free computer program for creating photo-realistic, three-dimensional scenes and a link for Mathematica users interested in generating POV-Ray files from within Mathematica, is discussed. POV-Ray has great potential in secondary mathematics classrooms and helps in strengthening students' visualization…

An exploration of the difference of two squares relates the formula to prime numbers.
