Describes how the cubic formula can be presented easily at the precalculus level, shows how to verify that the formula is correct, and identifies when it is profitable to use. (KHR)

Description of integrating one of the most widely used cryptosystems into a mathematics course for Liberal Arts majors. Application of this cryptosystem requires understanding of the concepts of exponentiation and modular arithmetic only. (MM)

Describes how fisheries research and management data (available on a website) have been incorporated into an Introductory Statistics course. In addition to the motivation gained from seeing the practical relevance of the course, some students have participated in the data collection and analysis for the New Hampshire Fish and Game Department. (MM)

Use of applets in classroom demonstrations encourages students to use them in homework problems. These applets are dynamic and do not have the syntactical or procedural stumbling blocks associated with most software or textual material, so students can begin exploring and learning immediately. (MM)

Both computers and calculators are limited by architecture, operating system, and software, to some predetermined level of precision within decimal number presentation and calculation. However, there exists a base that produces a terminating decimal. (MM)

Description of a technique in Maple programming language that automatically prints all paths of any desired length along with the name of each vertex, proceeding in order from the beginning vertex to the ending vertex for a given graph. (Author/MM)

The widespread interest in sports in our culture provides an excellent opportunity to catch students' attention in mathematics and statistics classes. One mathematically interesting aspect of volleyball, which can be used to motivate students, is the scoring system. (MM)

The notions of pentagonal numbers and partitions can be understood by students at the precalculus level, and should work well in a first course in programming for high school or college students. Presents opportunities to conjecture properties of partitions from a computer program. (Contains 14 references.) (Author/ASK)

Provides nine examples of one assignment in which students were asked to write a brief description of an assignment to be posted on the web for all class members to read. (Author/ASK)

Discusses the ways in which online assessment of student understanding of previous lessons was used in an undergraduate linear algebra course. (ASK)

Presents three geometric problems from a workshop for in-service algebra teachers to help them make connections between the mathematical concepts that they know and the drawings that they were required to display on their graphing calculators. (ASK)

This brief investigation exemplifies such considerations by relating concepts from number theory, set theory, probability, logic, and calculus. Satisfying the call for students to acquire skills in estimation, the following technique allows one to "immediately estimate" whether or not a number is prime. (MM)

Presents a brief overview of dynamical systems. Gives examples from dynamical systems and where they fit into the current curriculum. Points out that these examples are accessible to undergraduate freshmen and sophomore students, add continuity to the standard curriculum, and are worth including in classes. (MM)

Explains a non-standard definition of an ellipse familiar to astronomers and workers in celestial mechanics but which is not usually given in undergraduate text books on mathematics. (MM)

Explores an unexpected connection between a function, its inverse, and the arithmetic mean, algebraically and graphically. (MM)
