Project Scope„Wissenswerkstatt Rechensysteme “ (WWR)(in English „Knowledge Factory for Computing Systems“)
► goal of the project► modular system of multi-media based
teaching and learning modules
► 150 reusable modules reflecting thefundamental standard of knowledgein the field of computer engineering
► flexible combination of modules tocomplete courses
► support for face-to-face teachings and self-study
► basic technology - XML► platform independent
► separates content and presentation
► various processing possibilities

<ML>3 Goals
► Why another XML-based document description format for teachware?or
Demands for the underlying document format.(development started in May 2001)
► adaptability for different learning situations / scenarios,e.g. full-time studies, independent and tutorial learning
► consistency of content prepared for different scenarios,e.g. slides to be used during lectures and the matching printable scripts for offline reading
► flexible handling of which and how content is to be presented
► vocabulary covering all aspects needed to implement teachware in the field of Computer Engineering

<ML>3 Concepts - Scaling
► inheritancechild node gets scaling values from parent node in case of no explicit scaling
► restrictiononly subsets of the parents scaling values are allowed for the child nodes

MMiSS Workshop in Bremen, 22th and 23th April 2004
<ML>3 Concepts – Metamodel
► connecting more than one didactical part to the modules content side
► support for other kinds of didactical structures

<ML>3 Feature Overview
► scalability► intensity, target, device► didactical structure
► content blocks► covering the most important information classes
− example, description, definition, algorithm, theorem, …
► content markup► text enriched with additional information
− emphasis, footnote, abbreviation, citation, index, reference, …► mathematical expressions through embedded MathML
− inline, separate paragraphs► multimedia components
− images, animations, videos, sounds, applets, 3d-scenes, …− annotations to describe them− image sequences as an alternative presentation format (in case of missing
plug-ins)
