the test candidates with some existing material. The success of the candi-
dates converting the material can be regarded as an indicator of the degree
of usefulness of the created framework.
• Evaluation of the comprehensibility of the 3-Layer-Model by teachers:
It is important for this work that the 3-Layer-Model is comprehensible to
teachers. Since the 3-Layer-Model is so crucial to this PhD project, the
3-Layer-Model and the EFTECS are used and therefore evaluated in both
markup tasks.
• Evaluation of the comprehensibility of TLSs:
One of the major aspects of the 3-Layer-Model is the concept of TLSs based
on EHPs. The understanding of this concept is of high importance for the
framework.
• Evaluation of the HEAT and the created output of the HEAT:
The last general objective of this evaluation is to test the participants’ un-
derstanding of the HEAT. Furthermore, their impression concerning the pro-
duced educational hypermedia content of the HEAT is regarded as important
for the evaluation and discussion of the test results.
Pre-test interview
The pre-test interview was introduced in this evaluation to form a knowledge base
concerning the educational background and IT-skills of the test candidates. During
the interviews the teachers were asked the following questions:
• Could you please give some personal details?
No personal details of the test candidates will be discussed in this thesis.
However, the personal details were important to get a complete overview of

This question was important to get an insight into the candidates’ educa-
tional background, e.g. their teaching style. The information gathered here
