This ESTEEM module in the Biometrics Category is a collection of workbooks has tools for linear regression, polynomial fit, and chi-square analysis to test whether a data set is in Hardy-Weinberg Equilibrium.

In this article we present a collaborative environment of open source tools around the dynamic mathematics software GeoGebra that gives educators the freedom to create new and modify existing materials in an online community.

A mathlet for constructing graphs of functions of a complex variable, using color as the fourth dimension.
Flash CS3 (Actionscript 3.0) templates and classes for graphing functions in one variable as well as parametric curves in rectangular or polar coordinates.
Gauss-Kronrod Integration is an adaptation of Gaussian quadrature used on some graphing calculators. This Java applet outlines the mathematical computations involved and visually demonstrates the process the calculator uses to evaluate the integral.
The "area function" is often discussed as part of an introduction to the definite integral. This applet provides an innovative approach to producing functions drawn with a mouse in the context of an exploration/demonstration of the area function.
A report on the use of the Connected Curriculum Project materials in multivariable calcus and differential equations at the University of Canterbury in Christchurch, New Zealand.
Two applets for giving students some hands-on practice with cycle notation and composition of permutations.
This utility uses the free Flash player plug-in resident in most browsers to allow the user to plot a parametrically defined surface on a customized scale and dynamically rotate the three-dimensional picture.
An article describing the development of a database for online formative assessment to be used as independent or supplemental material for a precalculus course.
