• The EFTECS should allow the import of already existing educational mate-
rial.
Another important aspect that has to be considered in the design of the
framework are import functionalities for already existing educational ma-
terial.
Furthermore, it has been decided to apply a top-down approach to analyse ed-
ucational hypermedia content and to build the EFTECS based on this analysis.
This top-down approach will look at the educational hypermedia content in the
following order:
1. At an Educational Module (EM) Layer, e.g. complete courses and modules.
2. At a Teaching and Learning Strategy (TLS) Layer, e.g. single lectures or
teaching components which form a complete EM.
3. At an Educational Hypermedia Primitive (EHP) Layer, e.g. the elements
such as a question or an answer of a question and answer teaching and
learning strategy, forming a single TLS.
The three different layers, the communication between the layers and their work-
ing together, as shown in figure 1, will form the basis of the EFTECS analysis.

Based on this analysis, the EFTECS is able to grow in size and complexity.
