7.4 Summary 7 PRACTICAL EVALUATION
7.4 Summary
Before the results of the interview evaluation and the results of this practical eval-
uation will be discussed in the next chapter, a brief summary of the results of the
practical evaluation will be given.
7.4.1 EHP-Layer
During the practical evaluation study of this project the EHPs and therefore the
EHP-layer of the EFTECS worked within the expected boundaries and without
any major problems. The only limitations found were that new EHPs will have to
be designed if new TLSs are needed. This creation of additional EHPs has to be
done thoroughly, because they have to fit into the created framework and support
the prerequisites established in chapter 3.
However, the EFTECS is designed to exactly fulfil this requirement.
7.4.2 TLS-Layer
Generally, it can be stated that the TLSs already implemented in the HEAT cov-
ered most parts of the educational material.
However, it was discovered that for specific material new TLSs are needed. Those
new TLSs must be researched in detail and new EHPs implemented accordingly.
For example, during the conversion of existing educational material with the HEAT,
a Mind-Map-TLS would have been necessary, whereas during the creation of new
material a Programming-Code-TLS was suggested.
Altogether, the possibility of introducing new TLSs into the EFTECS framework
is built into the framework and therefore is no problem as long as the correspond-
ing EHPs are properly designed.
Obviously, the TLSs would also have to be implemented into the HEAT, but this
is regarded as a pure implementation problem and would not have to be addressed
during research work in the future.
