3. While software scripts are similar to each other, graphic 
user interfaces can be substantially different. The 
effectiveness of the GUI design could be an important factor 
influencing learning hence needs to be accounted for. We 
need to understand the inherent drawbacks of the menu-driven 
tutorial system, which may be overcome through inclusion or 
substitution of script-based systems. 
4. Finally, more studies need to be conducted. Different 
methodologies should be used. For instance, qualitative 
methods such as focus group procedures may well provide 
additional insight on the subject.
