MathDL—the Mathematics Digital Library

techexplorer and MathDL: Robust Support for Dynamic Web-based Mathematics

A major obstacle facing the National Sciences Digital Library (NSDL) is lack of support for the rendering and manipulation of mathematics in web browsers. This project will address that shortcoming by continuing the development of Integre techexplorer, a cross-platform, cross-browser plug-in originally developed by IBM Research that renders mathematics written in either MathML or TEX markup. Dynamic mathematical expressions are supported using techexplorer’s application programming interfaces (APIs). With further development, techexplorer will also provide consistent cross-platform browser support for wysiwig equation editing and document annotation, making techexplorer a robust development and delivery environment for interactive mathematical content and web services.

The techexplorer and MathDL project development is sponsored by the National Science Foundation and the National Sciences Digital Library under NSF grant DUE 03-33694.

MathQuery—the Mathematical Query Language

MathQuery: Improving Computer-Based Mathematics Assessment Using XML

This SBIR Phase I project seeks to determine the feasibility of creating a radically new method for analyzing and evaluating free-form student responses within computer-based assessment and tutorial systems for mathematics. Dubbed MathQuery, this method will allow a computer-based system to compare the structure of a student’s response to a problem against a rule set that characterizes how the problem can be solved, thereby identifying precisely how a student formulated the response and what errors may be present.

The MathQuery project development is sponsored by the National Science Foundation under NSF grant DMI 03-40418.
