Motivation
Goal Prototype an Internet-based distance learning environment at TU
Braunschweig
Components Technical infrastructure (network, multimedia teaching rooms) Tools for learning and collaboration (asynchronous and synchronous) Learning and teaching material
Interdisciplinary project Partially funded by the Ministery of Research and Culture in Lower
Saxony, Germany– October 1997 to September 1999
Project members– 2 computer science, 1 electrical engineering, 2 didactic and evaluation
Internet

Technical Infrastructure
Networking Stepwise improvement of campus backbone
– ATM-technology since it can provide quality of service
Room equipment Teacher desk with monitor, network access, beamer access ...
– Easy access to mutimedia and distance learning equipment and content
– Enables simple synchronous tele-teaching of a course
Internet

MACS: Modular Advanced Collaboration System
Goal Provide a framework for tele-collaboration Integrate dedicated support for tele-teaching
Characteristics Modular
– New applications can be integrated Portable and Internet-based
– Java-based Scalable
– Provides suited mechanisms for different collaboration scenarios
– E.g., tele-course, tele-seminar, tele-lab Interworking with ITU (Netmeeting) and Mbone protocols Visual session control
– Mediation of group awareness
– Control of access rights

To/oL
To/oL Tool for online/offline Learning
Characteristics Based on Internet technologies
– HTML, JavaScript, Java Usable with direct Internet access (online) or without (offline) Provides interactivity and virtual experiments
Interactivity Individual and free navigation through content Email access
Virtual experiments Configurable animations and simulations Questions and answers

Summary and Outlook
Distance learning support of EduNet Technical infrastructure that can be accessed by teachers and learners Enhanced and easy to use tools
– To/oL already used by other departments (e.g., chemistry) Multimedia-based content
– Virtual experiments
– Interactivity
Evaluation ... difficult, since current experience is very limited
Follow-up project together with University Hannover, TU Clausthal Improve and test tools Integrated asynchronous and synchronous tools (i.e., To/oL and MACS) Provide content for the diploma program information technology
