The Digital Classroom Resources (DCR) provides a select collection of free online learning materials which are available through the site. These materials have been classroom tested and peer reviewed.

Many items in the library are posted with editorial reviews and a link to a moderated discussion group focused on the materials.

Simple 3D Drawing This Flash Forum tutorial not only discusses the programming involved in rendering simple polyhedra in Flash CS3, but it also gives an elementary discussion of the mathematics behind 3D rendering on a 2D computer screen.		Flash Tools for Developers: 3D Graphers in ActionScript 3 This article describes classes for 3D graphing revised for AS 3. Along with class files and documentation, we provide several templates to show how to use the classes for graphs of functions of two variables as well as parametrically defined surfaces.
Flash Fractal Maker Useful for teaching as well as artistic endeavors, this applet allows the user to build a "seed" for a recursive process that constructs complex and fascinating fractal images.		Actionscript 3 Tutorials A collection of mathematics applets with full documentation and source code for beginning users of Adobe Flash. This collection is part of the MathDL Flash Forum.
Flash Tools for Developers (AS3): Graphing curves in the plane Flash CS3 (Actionscript 3.0) templates and classes for graphing functions in one variable as well as parametric curves in rectangular or polar coordinates.		MathDL Flash Forum A forum for educators interested in developing mathematics classroom material using Adobe Flash.
Biological ESTEEM Excel Simulations and Tools for Exploratory, Experiential Mathematics (ESTEEM) is a project of the members of the BioQuest Curriculum Consortium.
