This article analyzes the physical and mathematical properties of the mirascope and models the mirascope using dynamic learning technology

This ESTEEM module in the Biometrics category creates graphical images of a certain type of fractals (Iterated Function Systems) that can be constructed by linear transformations.
A suite of mathlets for interactive exploration of quadric surfaces
This mathlet computes Riemann sums for a user-defined function and draws a graph of the function as well as a graphical represenatation of the approximations.
This is a pair of (1D and 2D) SOCR Activities that demonstrate random sampling and fitting of mixtures of Gaussians to model complex data (e.g., multimodal).
This applet, designed as a limited computer algebra system, allows the user to evaluate mathematical expressions, including those of interest in a calculus class.
A preparatory module for problem-solving in physics and calculus that covers systems of units, dimensional analysis, significant figures, estimation, and orders of magnitude

Chemical Graph theory is used to model physical properties of molecules called alkanes. Java applets allow for interactive exploration of molecules. A student project and discussion of its application are included, along with spreadsheets of model data.

In this article we examine several specific geometric phenomena in Euclidean space and calculate the asymptotics as the dimension gets large.
This applet uses the free Flash player plug-in resident in most browsers to allow the user to plot a parametrically defined curve on a customized scale and dynamically rotate the three-dimensional picture.
