Starting Point: Technology Education
- for technology education exists no textbook

- permanent changes of contents

- contemporary technology education

- wide range of sources of teaching material

- very time consuming and therefore inefficient

 MM-Learning: Coherent Conception
      The rendering of multimedia learning
     linking together three essential steps:
1. Creation of multimedially oriented (study-)objects
2. Developing of combined (study-)objects
3. Use of study-objects (modules) in study platforms
Multimedially oriented (Study-)Objects
A modular approach is currently being developed
   within the framework of different projects:
                                      BMBF
                  Federal Ministry for Education and Research

               Supporter of the Project New Media in Education

- Modules (Learning Modules)
- Objects (picture, closed text, applet, animation,...)
- (Study-)Objects (neccassary to develop)
