9 CONCLUSIONS
In this chapter the evaluation of each of the objectives of this study will be ad-
dressed in turn. The problems and issues that were discussed in chapter 8 are
reconsidered in the light of the evaluation of the objectives of the study.
The chapter will conclude with suggestions for further work and research.
9.1 Research objectives
The three main objectives of this research project, as they have been identified in
the literature review in section 2.13 and as they have been addressed during the
evaluation and discussion chapters, have been accomplished as stated below.
9.1.1 Creation of a suitable framework for content separation
The creation of a framework for the separation of educational from technical con-
tent in educational hypermedia was suggested after the literature review and was
accomplished at the beginning of this PhD project. The created 3-Layer-Model
based on EHPs, TLSs and EMs resulted in the EFTECS framework and addresses
the separation of educational and technical content in educational hypermedia.
One of the most important issues of this work was the creation of the fine-grained
EHPs of teaching and learning strategies within the EHP-layer of the framework.
This framework was developed as described in chapter 3. Further on, the EFTECS
formed the basis for the XEML and the HEAT and was designed for further ex-
tensibility in the future. This extensibility allows the introduction of new EHPs
and TLSs as long as the basic EHPs, e.g. HELP-EHP, are included.
The results of the interview evaluation in chapter 6, the practical evaluation in
chapter 7 and the discussion in chapter 8 show that the EFTECS can be success-
fully and effectively used for the separation of the educational and the technical
content in educational hypermedia.
However, some specific limitations of the framework were discovered especially
during the interview evaluation. For example, the complexity of the framework
