Overview

The goal of this project is to leverage the power of open social learner modeling and adaptive navigation support in the context of the envisioned Personalized Assistant for Learning (PAL). The project is supported by the Advanced Distributed Learning Initiative contract W911QY13C0032.

The project focuses on both exploration and implementation of adaptive navigation support and open social learner modeling and pursues three directions of work

  • Exploring open social learner modeling interface for diverse learning content
  • Enhancing algorithms for personalized guidance using knowledge-based and social approaches
  • Developing architectural solutions and authoring tools to support open social learner modeling

Open Social Learner Model Interface

Mastery Grids

MG
Our latest implementation of Open Social Learner Modeling (OSLM) is Mastery Grids Interface system. Mastery Grids is both, a innovative OSML interface and an 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.

Mastery Grids is a visual-rich, interactive, adaptive E-learning system and framework with integrated functionalities enabling multi-facet social comparison, open social student 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.

Architecture

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:

  • 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.
