9.2 Future work
The work on this PhD project also revealed several problems. Those issues pro-
vided significant insight into the topic, even if not all of them could be solved
within this study.
The problems that could not be solved during this project will have to be addressed
in the future.
9.2.1 Long term evaluation of the framework and the HEAT
It would have been ideal if there had been the opportunity for a long-term eval-
uation of the 3-Layer-Model, the EFTECS and the HEAT. Additionally, the ex-
periments could have had even better results if there had been even more teachers
from different teaching levels.
For example, the HEAT could be used at a school or a university for one or even
better two years. This would allow in-depth insights into the usability of the
EFTECS and the HEAT as well as the creation of a significant content space.
Furthermore, the analysis and development of additional TLSs and EHPs could
be undertaken in a real-life teaching scenario.
Another approach could be to use the framework and the HEAT in different teach-
ing institutions but involving work with students from the same level. This ap-
proach could especially provide results concerning the reusability of educational
content.
However, the time frame and the budget of this PhD project only allowed for the
undertaken experiments.
9.2.2 Implementation of additional TLSs
The most important issue that will have to be addressed in future work is the
analysis and implementation of additional EHPs and TLSs. During the interview
evaluation, but especially during the practical evaluation, it was shown that the
EHPs and TLSs implemented in the HEAT are not sufficient for every aspect
