Curriculum management using web intelligence

Extract

[...] An Intelligent Tutoring System should be typically strongly adaptive, working in a wellstructured information space; gathering data about the user's movements and using this information to dynamically modify the presentation and functionality of the system in clearly defined ways. It is again to emphasize that adaptivity is not a technology, but a goal. Adaptivity is a common functional goal of intelligent systems. In summary, for a system to be called an adaptive system it must have the following characteristics [Eklund & Brusilovsky, 1999]: a. [...]

The learning material is designed and organized through XML document type definition in such a manner that the material can be searched using its class with the unit, topic and the lesson number.

[...] A lesson level adaptivity guided by the learners' knowledge level at each stage of lesson generation has been proposed and its implementation through computational intelligence techniques has been shown. The ANFIS directed lesson generation process alongwith class-oriented content structure provides real adaptivity. Following are the salient features and advantages of the proposed approach: i. An adaptive rule based approach provides the advantage of rule flexibilty. While we have shown a rule base designed on the basis of expertise gathered from several teachers, an individual teacher's expertise can also be formalised to reflect a personalized judgment. [...]

[...] Thus, using the class type taken from the ANFIS, the aggregation module simply retrieves the content pointers and submits them to the transformation module for subsequent processing ANFIS-BASED LESSON AGGREGATION MODEL As already described, adaptive network based fuzzy inference system utilizes a backpropagation algorithm or a hybrid algorithm to tune its parameters from the input-output data pairs. In case of lesson generation process, the rules are taken from the human experts. The criterion for rule framing is based on the learners' knowledge level. [...]
