**6.4. Knowledge domain**

An adaptive e-instruction system (AHS/hypertext) within the present scope requires a database containing natural semantic networks similar to those described earlier. Here, templates are data structures containing SAM groups and their semantic values in which information can be accessed by a PROLOG-based inference engine. As the sample for developing these SAM groups is enlarged, better predictions for adapting navigational support can be achieved.

## **6.5. Interface**

As shown in **Figure 11A**, when a student begins a learning session, she/he is presented with a menu of options of the course content.

Before and after exploring each module, a semantic priming study must be performed to provide the expert system module with information for adapting the navigation support by modifying the link structure in a module based on a meaning formation template. After a Formative E-Assessment of Schema Acquisition in the Human Lexicon as a Tool in Adaptive… http://dx.doi.org/10.5772/intechopen.81623 83

module or an entire course is completed, the user can obtain a cognitive performance report (**Figure 11B**). This report serves as explicit assessment results that empower a user to adapt the searching of content (encouraging adaptability), whereas the link modification is an implicit message of corrective adaptability to improve proper meaning formation of the content. Selection of learning activities either using hypermedia or by modification of knowledge content depends on the expert model's evaluation of the user's meaning formation.
