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
Database for Technology Education

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
9
Multimedially oriented (Study-)Objects
A modular approach is currently being
developed within the framework of different
projects
BMBF Federal Ministry for Education and Research
PT-NMB Supporter of the Project New Media in
Education
- Modules (Learning Modules)
- Objects (picture, closed text, applet,
animation,...)
- (Study-)Objects (neccassary to develop)

Focus DB for Technology Teacher Education
- specific use of new media
- especially developed database
- mutimedia in technology education
- conception of modularity
- combining contents to superordinate contents
- requirements for a database in technology
education
11
MMDB-TU and INTEGER
Focus Requirements for a Database
- add, access and execute, multimedial
- no commercial solution / open source
- independance of any operating system
- MySQL, PostgreSQL
- MySQL is the base of the MMDB-TU
- L.A.M.P.
