This page is for the ADL project.

Description

PAWS participation in ADL is focused in the development of MasteryGrids system. Mastery Grids is a visual-rich, interactive, adaptive E-learning platform with integrated functionalities enabling multi-facet social comparison, open user modeling, and multi-type learning materials support. It presents and compares user learning progress and knowledge level (mastery) by colored grids, tracks user activities and feedbacks dynamically and provides flexible user-centered navigation across different content levels (e.g. topic, question) and different content types (e.g. question, example) of learning materials. The architecture supporting Mastery Grids fulfills a major objective, portability, which is the ability to be integrated to other systems with little set up and modification. The architecture is modular and includes different software components:

• frontend user-system interaction interface, the Mastery Grids Interface,

• backend Aggregate services communicating between the main interface and user modeling services,

• backend user modeling services, and

• backend content providing applications.

An overall architecture of the system can be sen in the next figure.
