8.2 Review of the HEAT 8 DISCUSSION However, the design of the EFTECS and its implementation into the HEAT were proved to be successful during the practical evaluation of the study. 8.2.5 Linking of TLSs and EMs The interview and the practical evaluation of the HEAT showed that the linking of different TLSs of an EM was not as easy as expected. Those problems were identified in section 6.5.3 and in section 7.3.3. The first problem was the technical implementation of the linking process. It was decided to use an index approach for the HEAT, which proved to be difficult to understand for the test candidates, especially for the educational experts. This problem could be addressed by implementing the linking in a different way, for example a drag and drop approach or another visualisation technique. The second problem is the complexity of the structure the TLSs can form within an EM. The larger the EM becomes the more complex the structure of the EM can become. A possible solution to this problem could be that the author is not being offered the option of free linking between the different TLSs. Instead, different templates could be used, for example a strict book structure with sequential navi- gation through the content. The work on this problem should be addressed in the future. Finally, it has to be stated that the linking between the different TLSs is not the only problem that can occur, the limitation to only one EM at the moment can represent a problem, too. The theoretical linking between different EMs will have to be evaluated in detail. However, the EFTECS and the underlying framework is not the main issue of this problem, but their technical realisation in the HEAT. 8.2.6 Content space The reusability of content is one of the key components of the EFTECS and the HEAT. This reusability was addressed in the HEAT by the creation of the content space as described in section 4.6. It was stated by the test candidates that the content space approach could be imagined as a great support for their daily work. 190
8.2 Review of the HEAT 8 DISCUSSION However, during the practical evaluation of the author, several problems with the content space in its current form were identified. Firstly, as soon as some educational material is stored in the content space, the search for some specific material is not optimal. The content space needs some improved search functions and filter criteria exceeding the existing ones. This is not a major problem and should be soluble by some additional implementation within the HEAT. Secondly, at the start of the EFTECS and the HEAT there is no material in the content space available for reuse. To avoid every single bit of educational material having to be authored with the HEAT, it will be necessary to design, implement and evaluate some import functions to allow existing educational material to be imported into the content space. Finally, it was stated during the interview evaluation that a printing function for the created material was needed by the test candidates (cf. chapter 6). Furthermore, not only a printing function should be designed, but different export functions as well. The XML based design of the EFTECS is an optimal base for such export functions. 8.2.7 Quality of produced material One of the goals of this PhD project is to create educational material for usage and delivery via the World Wide Web. Therefore, it is necessary to address the quality of the material produced by the HEAT. During the interview evaluation in chapter 6 and the practical evaluation in chapter 7 it was observed that the authored material was converted into a WWW based format based on the EFTECS. This conversion step worked fine, but the quality of the converted material was relatively poor compared to the actual state of the art in web design, as far as for example the graphical design or the usage of multimedia content is concerned. This lack of quality is based on the fact that the HEAT was designed and im- plemented with limited resources. The further improvement of the HEAT must address these issues and could be done during future work (cf. section 9.2). 191
