6.Conclusion


	A generic web based information architecture for a learning environment has been 
proposed throughout this paper following discussion of abstracted system of a learning 
environment which includes a user, a system, and a controller. Customizability of the 
architecture allows the users to tailor their needs inside their learning environment. 
Interactivity is increased and they will not be overwhelmed by amount of the learning 
materials. Adaptable architecture brings challenges and new subjects to learn into the 
environment. It also results in better interactivity. 
	The architecture defines not only its components but also flow of events or 
information, which enables us to explain nature of a learning system better.
	Measuring interactivity in a web based learning environment was discussed, in an 
effort to establish the scientific foundation of measuring interactivity as a variable. 
Possible modeling techniques of the learning system were introduced along with a 
benchmark methodology to track user-system interaction data. The importance of 
interactivity in learning or education has been emphasized in several fields such as 
education, psychology, and sociology, but to measure the value of such variable could not 
be done in any of disciplines to date. By utilizing a paradigm from computer science, the 
task can be accomplished with legitimacy.   
	In this work, we suggest a possible framework as educational portals in terms of 
distributed educational objects. To implement each functionality is open but the way the 
architecture is designed enables us to employ current technologies over a distributed 
system. XML will be a good choice to be used at the application server from the 
information architecture because it is flexible in specifying object interfaces to each user 
and supported by growing number of tools.   

Future Work


	A complete modeling and simulation in a real time learning environment will 
reveal more data than the simulation performed in this work. The Modeling itself is 
challenging and a worth while to do. There are a few simulators available to test a 
modeled system. Most of them are originally built for industrial systems but more and 
more fields adopt such methodologies. 
	Also in abstracting the system, to consider event queues will be meaningful. That 
will be able to add concepts of sharing events or asynchronous/synchronous events into 
an information architecture. Such diversified event model will offer more sophisticated 
information architecture for a future learning environment.
