3 EFTECS 3 EFTECS In order to realise the separation of educational and technical content in educational hypermedia it is important to follow a systematic approach. The approach selected for this PhD project is to create a framework that describes the desired content separation and provides the basis for a practical feasibility study of a prototype authoring tool. From this point forward the created framework will be referred to as the : EFTECS - Extensible Framework of Technical and Educational Content Separation. In chapter 4 the implementation of an educational authoring tool based on the EFTECS will demonstrate the feasibility of the EFTECS. 3.1 Theoretical approach As outlined in the introduction and the literature review it is important to separate the educational components from the technical components in educational hypermedia in order to simplify the authoring process of educational hypermedia material. It has also been mentioned that these two components are generally tightly woven together. Therefore, the separation of the two components is one of the most important issues of this PhD project. The EFTECS is designed to provide an easy to use model to separate the two components from each other. The general concept of the separation has already been shown in the existing work [14][121] in the field. In the literature review the drawbacks of the competing approaches have already been addressed (cf. section 2.7). However, it is necessary to point out the most important aspects once again: • The EFTECS should be based on educational teaching and learning strategies. The major focus of this work is based on the simplification of the authoring 74
3.1 Theoretical approach 3 EFTECS process of educational material for educational experts. The most promis- ing approach to achieve this simplification is to use a model that educational experts are used to. Special focus will be laid on the very detailed analysis of the components of the teaching and learning strategies as identified in section 2.7. • The EFTECS should provide the complete separation of educational and technical content. A partial separation of the components would simplify the technical implementation of the model. The higher the degree of separation will be, the more difficult the technical implementation of the EFTECS will become. This relation is based on the fact that educational material which is tightly woven together, e.g. a web page, can easily be authored by a technical expert without an authoring tool. If an educational expert with some technical expertise wanted to design the same web page, he would need an authoring tool, for example “Front Page”. However, if the authoring process is simplified so much that the educational expert does not need any technical knowledge at all, which is the desired state since he can concentrate on his educational task, then he will need a well-designed authoring system that focuses on his educational skills. • The EFTECS should be easily extensible to allow further development and reuse of material. It is very important for the acceptance and further development of the EFTECS that the authored material is as easy to reuse for different purposes as pos- sible. This issue has to be addressed in the EFTECS and will allow the educational expert to search, find and reuse educational material that has already been authored . • The EFTECS should be applicable in practical authoring. It is not desirable to just create a theoretical model which is not usable in a practical situation. Therefore, it is not only the EFTECS that has to be designed, but a feasibility study in form of a prototype also has to be designed, developed and tested. This prototype will be introduced in chapter 75
