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).

An **article** describing the development of a database for online formative assessment to be used as independent or supplemental material for a precalculus course.

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 **mathlet** for exploring solutions of the Transport Equation by the method of characteristics.

This article explores how mathematical techniques, digital images, and dynamic geometry software can be used to analyze a real-world situation originating from poultry science. The topic is mathematical modeling of the shape of an egg, where the underlying question is: What is the volume and surface area of a hen's egg?"

n this note, we describe our policy on a number of basic issues related to writing style, reference style, and the format of JOMA articles.

This utility uses the free Flash player plug-in resident in most browsers to allow the user to plot 3D curves and surfaces on a customized scale and dynamically rotate the picture.

This **module** uses a small sample of the applets in the Mathlets package together to explore exponential functions and their derivatives in depth.
