4.3 EHP-Information
During the work on this PhD project it was discovered that several attributes of
the EHP-layer of the EFTECS can be generalised and can also be used for the
TLS- and EM-layers. All the information that is not directly connected with the
learning content of an EHP will be summarised in one globally used layer: EHP-
information-layer.
4.3.1 Design aspects
Before the creation of the EHP-information-layer it is important to identify the
information of the EHP-layer which can be shared globally. After re-evaluating
the model the following parts of the EHP-layer were restructured into the EHP-
information-layer:
• Domain related information
• Adaptation related information
• Physically related information
• Additional information
The selection of these specific information packages is based on the assumption
that the information can be used for every single EHP, every TLS and every EM.
For example, it does not make a difference whether the domain information of
an EHP or an EM is stored in the same logical construct. Therefore, the EHP-
information-layer meta-data will not only be used for EHPs, but also for the TLSs
and the EMs to implement reusability and structured storage of the TLSs and EMs
as well.
The actual specification of the domain information or some of the adaptation re-
lated information can be very challenging, for example the level of difficulty of
some educational material will always be different for experts, teachers or stu-
dents. Therefore, some of the needed meta-information must be discussed and
agreed upon before it can be used within the HEAT. However, this discussion
