6.4 Analysis of the HEAT based markup task 6 INTERVIEW EVALUATION
Furthermore, it was observed that the few problems the evaluation subjects had
during the manual markup tasks did not come up during the HEAT based markup
task. None of the evaluation subjects needed another explanation of the EFTECS
and the 3-Layer-Model, but focused primarily on the creation of the educational
material.
6.4.3 Educational experts
At the beginning, the educational experts had some problems with the HEAT soft-
ware. They were quite confident about the tasks they were given, but needed more
time to get confident with the HEAT than the technical experts.
However, it was observed that once the difficulties in using the unknown HEAT
were solved, the educational experts were using the TLSs and the included EHPs
almost naturally. Furthermore, the presentation of educational content via EHPs
was no problem for the educational experts.
Additionally, the educational experts were using the linking functionality between
the TLSs in a way similar to the way they linked the contents during the manual
markup task, i.e. very individually. This can be regarded as a successful conver-
sion of the EFTECS into the HEAT as the linking with the HEAT represents the
semantic linking of the TLSs.
6.4.4 Technical experts
The technical experts were very confident about the HEAT after a short time. The
experts from this group did not have the starting problems the educational experts
had.
However, the technical experts did not so much focus on the educational side of
the HEAT, but on the technical realisation of the EFTECS. Especially the content
space and the reuse of the educational material was of high interest to the technical
experts.
Finally, all of the technical experts were able to successfully create the educational
material of the HEAT markup task (cf. section 5.2). This also shows that the
