8.2 Review <strong>of</strong> the HEAT 8 DISCUSSION<br />

Altogether, the conversion <strong>of</strong> the pre-existing material revealed several problems<br />

<strong>of</strong> the HEAT. Therefore, it was decided to create some additional material from<br />

scratch to evaluate those problems and to gain some further insights into the ca-<br />

pabilities <strong>of</strong> the HEAT.<br />

8.2.4 New material<br />

After the conversion <strong>of</strong> pre-existing material (cf. section 7.2) it was decided to<br />

verify the gained insights by creating some educational material from scratch.<br />

The creation <strong>of</strong> material in a domain where the author was not only a technical ex-<br />

pert but an educational expert as well, was successfully completed and described<br />

in section 7.3.<br />

In comparison to the conversion <strong>of</strong> pre-existing material it was stated that it was<br />

much easier to create educational material with the HEAT if the material was taken<br />

from the author’s own knowledge domain.<br />

Since the usability <strong>of</strong> the HEAT was shown during the interview evaluation, the<br />

fact that the author’s expertise and knowledge in the domain <strong>of</strong> the educational<br />

material had a direct influence on the usability <strong>of</strong> the HEAT must lead to the con-<br />

clusion that the HEAT and the EFTECS are designed in a way that the educational<br />

background <strong>of</strong> the author outweighs the his technical experience. Additionally, it<br />

seems that it is easier for the author to use the HEAT and the EFTECS if he has<br />

got some expertise and knowledge concerning the educational domain.<br />

At another point <strong>of</strong> the creation process, it was discovered that additional TLSs<br />

would be helpful to improve the usability and handling <strong>of</strong> the HEAT. The observa-<br />

tion that additional and specialised TLSs are needed in the HEAT was also made<br />

during the practical evaluation and the interview evaluation. It can therefore be<br />

stated that future work (cf. section 9.2) will have to address the creation <strong>of</strong> such<br />

additional TLSs. The design <strong>of</strong> the EFTECS and the HEAT is expected to allow<br />

that without major problems.<br />

Altogether, the practical evaluation <strong>of</strong> the HEAT showed that there were some<br />

minor problems which will have to be addressed in the future.<br />
