6.5 Analysis of the post-test interview 6 INTERVIEW EVALUATION
even bigger problems solving the linking task than the members of the technical
experts group. One major problem was the representation of link source and link
destination by indexes.
As a solution to this linking problem 33% of the evaluation group suggested an
approach that included a drag and drop representation of the links (cf. table 40 on
page 254).
Furthermore, 66% of the candidates stated that the linking was not self-explanatory
and that most of them could not have solved the task without additional help (cf.
table 40 on page 254).
Moreover, it has to be taken into consideration that the linking of educational
material could also be regarded as a technical barrier. A possible solution would
be to offer the author of the educational material some guidance or templates for
the creation of courses and to free him of the linking task.
6.5.4 Reuse of material from the content space
The reuse of the existing material was regarded as an excellent and easy to use ap-
proach by 77% of the evaluation group. Furthermore, 22% said that reusability of
educational material could save a lot of time for the author of educational material
(cf. table 41 on page 254).
However, the test candidates also stated that the usability of the tool has to be
improved and furthermore addressed several additional issues (cf. table 42 on
page 255) that would have to be taken into consideration during any further de-
velopment of the HEAT:
• Copyright issues of the material will have to be addressed in the future.
• Filters, queries and even better text-search possibilities through all the files
are needed.
• The database could become too big and have redundant content areas.
• Students must not have the same access rights as the teachers.
