This applet allows the user to test a graph for planarity by simply dragging the nodes around until the graph's edges don't cross. Fixed exercises and an interface for drawing your own graph are given.

In this applet, a user fills in a grid to create a distribution of numbers. The applet displays the size of the standard deviation and the position of the mean in the distribution. An activity is provided to facilitate the use of the applet to investigate standard deviation.

A Biological ESTEEM module in the Genetics Category. This workbook simulates a linkage analysis problem with up to four alleles.

This suite of five interactive applets (written with GeoGebra) allows exploration of definitions and theorems commonly presented in first-year analysis courses. Topics include sequence convergence, continuity at a point, the Mean Value theorem, Taylor series, and Riemann sums. Included with each applet is a pair of activities: one for becoming comfortable using the applet, and one for using the applet to explore the associated topic in depth.

This article explores the geometric interpretation of fractional integration with the aid of several animated images.

This paper describes a Flash-based OSSLET that we have used at the United States Military Academy with first year calculus students as a vehicle for motivating vectors, matrices, and linear and affine transformations.

A Biological ESTEEM module in the Epidemiology Category. This worksheet implements an SIR (Susceptible/ Infected/ Resistant) model of epidemiology for vector-borne diseases.
