Describes a teaching experience through student-centered activities in a second year algebra class with gifted and talented students. Concludes that students learned more mathematics than the teacher originally planned to teach. (KHR)

Describes how to teach the coefficient of determination and correlation coefficient. Includes a worksheet for correlation and regression activities. (KHR)

Correlates high school chemistry curriculum with high school algebra curriculum and makes the case for an integrated approach to mathematics and science instruction. Focuses on process integration. (DDR)

Presents attributes of different types of software including Logo, geometric packages, graphical packages, and spreadsheets, each of which offers different opportunities for learning. Investigates the different ways in which the software allows for performing the given task so as to make the mathematics of the task explicit to users. (KHR)

Describes a classroom inquiry into expressing the number pi as the limit of a sequence of different ratios using relationships among coins and the radius of an inscribed circle. (KHR)

Describes an activity designed to demonstrate the birthday paradox and introduce students to real-world applications of Monte Carlo-type simulation techniques. Includes a sample TI-83 program and graphical analysis of the birthday problem function. (KHR)

Presents a way of using greeting cards created by graphing calculators to teach the transformation of functions. Illustrates the steps of making a calculator greeting card and students' descriptions of transformations. (KHR)

Presents a mathematics review game appropriate for middle school or high school students that requires all students to participate. (Author/NB)

Presents an activity in which students gather and analyze data involving the compatibility of human blood types. Uses student surveys, Venn diagrams, and random numbers. Includes activity sheets. (Author/NB)

Presents a mathematics game appropriate for middle school or high school students that aids in the teaching and understanding of closure properties. (Author/NB)

Demonstrates how fictitious anecdotes, especially humorous ones, can be used to teach statistical concepts effectively and to dispel some common misconceptions in statistics. (ASK)

Explores a birthday-related problem that asks about the probability of having people with the same birthday in a room. Utilizes spreadsheets to work on the problem and discusses related teaching issues. Contains 20 references. (ASK)

To introduce students to the concept of proving a theorem, a simple deductive system is necessary where the rules are few and can be understood quickly. Presents games with this aim in mind. (ASK)

Explores how students interpret algebraic notation and what teachers can do to support appropriate interpretations. Presents two research-based strategies and concludes that in the face of reform and technological advances, finding a definition for symbol sense takes on added significance. Contains 22 references. (ASK)

One way to assist students in developing correct intuitive ideas about the effect of sample size is to allow students to simulate similar problems. Describes experiences with classes performing simulation using graphing calculators. (ASK)
