The Xmath Calculator
Odd Bringslid

The dMath Project

The dMath project is a follow-up to Xmath and is intended to be an industrialization of the Xmath project. This project will develop a European database of mathematical e-learning modules. These modules are independent but may be combined in an arbitrary way to set up a course in web-based mathematics.

The system contains three main parts:

1. The authoring suite (working title SciLas) has two pieces: an environment to write and store mathematical content trees, which are a collection of reusable learning objects organized in modules, and an environment to publish and download these learning objects with the capability to reorganize them into a course. The content trees are accessible through a web browser using predefined style sheets. Storage requires preliminary authorization and approval (dMath development server).

2. The dMathArchive, based on this system, is a collection of modules (see Figure 1).

3. The Xmath calculator, based on webMathematica, is to be used by developers, publishers, and course students to do calculations on the web. The calculator gives rules and steps in a calculation as a professor would do it on the blackboard.

The module design is important for adoption of local conditions and to enhance flexibility. Publishers may download modules from the archive in an arbitrary way and link them into a course in web-based mathematics. This collection of modules may be used as a mathematical dictionary as well.

In the dMath project we will focus on the needs for upgrading and furthering the education of teachers and engineers in mathematics. This is in accordance with national and European strategies for these target groups especially and for life-long learning in general. Because dMath is strongly innovative and uses new technologies (MathML, webMathematica, and innovative database design) other potential users may be publishers, people in computer science, content providers of scientific e-learning material, and researchers and developers.
