There is much research that documents what many teachers know, that students struggle with many concepts in probability and statistics. This article presents two sample activities the authors use to help preservice teachers develop ideas about how they can use technology to promote their students' ability to understand mathematics and connect…

This article examines levels of involvement of weekly church attenders in Catholic parishes in Australia, New Zealand and the United States through an analysis of data from the International Congregational Life Survey. Factor analysis was used to identify four questionnaire items related to parish involvement which were then combined to produce a…

The purpose of this study was to determine the effect of the TI-81 Graphics Calculator as an instructional tool on college algebra students' conceptual and procedural achievements involving functions and graphs and on the students' attitudes toward mathematics. The study was a posttest-only, equivalent control group design conducted with students…

The normal curve has long been important in statistics. Most interval variables yield normal or quasi-normal distributions when data are collected from large samples, and the normal "Z" distribution is also used as a test statistic (e.g., to test differences between two means when sample size is large, since "t" approaches…

Using a computer equipped with a plotter, graphs of linear equations and trigonometric identities can be produced. Examination of these graphs can aid in teaching solution of equations. (SD)

Two approaches to the teaching of logarithms are described. One is essentially algebraic while the other involves integration. (SD)

A dialogue between a student and a teacher is presented. The topic is the absolute value function. The discussion ranges from elementary algebraic properties to deeper properties of the function. (SD)

Similarity of parabolas and other conic sections is discussed. The theorem "Any two parabolas are similar" is deduced. (SD)

Using a set of worksheets, students will discover and apply Euler's formula regarding connected planar graphs and play and analyze the game of Sprouts. One sheet leads to the discovery of Euler's formula; another concerns traversability of a graph; another gives an example and a game involving these ideas. (Author/KM)

This article describes a series of activities and worksheets to provide students with experience in graphing number pairs. Students at different lev els can use the activities to relate basic arithmetical operations to graphs. (Worksheets are included.) (SD)
