button or via the menu bar of the HEAT. The additional TLS is needed to illustrate
the linking of the different TLSs.
Figure 11 shows the linking information dialogue of the Lecture-TLS. The author
can set up to five different links to other TLSs and each of them can be one of sev-
eral different linking types. The number of possible links was set to a maximum
of five due to reasons of implementation resources. Theoretically, an unlimited
number of links could have been implemented.
Every link can have a destination to another TLS which is selected by its individ-
ual index. In the example the Lecture-TLS is linked directly to the QA-TLS with
the index 1.
The different link types can and will be presented differently during the presenta-
tion of the EM to the student.
Figure 12 shows the created link and its representation within the HEAT. To im-
prove the overview of the TLSs and the connecting links, it is possible to turn the
display of the links on and off by pressing the right mouse button. Additionally,
the TLSs can be moved around and structured in the EM with a drag and drop
functionality.
If the author wants to add additional TLSs he can do so by using the process
