5.1 Analysis of alternative approaches 5 EVALUATION METHODOLOGY
The one-to-one approach was combined with the single session approach. There
is no necessity for sequential sessions because the main goal of this evaluation
was to get information about the EFTECS, the HEAT and the separation of edu-
cational and technical content on a fine-grained level (cf. section 2.13), but not
the examination of long-term effects, which can be addressed in the future work
(cf. section 9.2.1). However, the duration of the evaluation session was relatively
long due to the many tasks that had to be covered.
Finally, the results gained from the interview evaluation are supplemented by a
practical evaluation (cf. chapter 7) of the HEAT which aims at the evaluation
of the HEAT and the EFTECS by creating some educational material in a real-
life scenario and at the conversion of existing material and the creation of new
educational material. Such a practical evaluation is necessary to test the HEAT
and the EFTECS in a more real-life situation compared to the lab scenario of the
interview evaluation.
In the following the design of the evaluation sessions will be introduced.
