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. This is a joint project with Learning + Technology research group at Aalto University. The LeTech group at Aalto University focuses on developing several kinds of smart learning content for Java and Python programming that are compatible with the project architecture Aggregate.

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

We have prepared fliers for quickly getting to know our systems:

  • For researchers or system developers (designers), please check here.
  • For teachers or educators, please check the flier for your interested domain: Java, Python, or SQL.

Open Social Learner Model Interface: Mastery Grids

Mastery Grids Interface
Our latest implementation of Open Social Learner Modeling (OSLM) is Mastery Grids Interface. Mastery Grids is both an innovative Open Social Learner Model Interface and an adaptive E-learning platform with integrated functionalities enabling multi-facet social comparison, open learner modeling, and adaptive navigation support to access multiple kinds of smart learning content. Mastery Grids is supported by adaptive social learning framework Aggregate. This framework supports several kinds of open student modeling, social comparison, and recommendation. In detail, Mastery Grids presents and compares user learning progress and knowledge level using colored grids, tracks user activities with learning content, and provides flexible user-centered navigation across different content levels (e.g. topic, question) and different content types (e.g. problem, example). Our past research shows that open student modeling and social comparison effectively increases students’ performance, motivation, engagement and retention.

Architecture: Aggregate

Aggregate Architecture
We developed an adaptive social learning architecture Aggregate to support Mastery Grids interface. Aggregate is an extension of our original ADAPT2 architecture. On the top of ADAPT2 , Aggregate architecture supports several kinds of open student modeling, social comparison, content brokering, and recommendation services. The architecture 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.

Learner Modeling

CUMULATE
We have developed CUMULATE, a centralized user modeling server built for the ADAPT2 architecture, to provide user modeling support for adaptive educational hypermedia (AEH) systems. CUMULATE allows flexible learner models to infer learner knowledge. Mastery Grids's architecture is supported by CUMULATE and thus it also supports flexible learner models. The explanation of the communication between the interface and learner model can be found in Aggregate. We have proposed and implemented different learner models over past years, including asymptotic assessment of user knowledge which is the main one currently deployed in our systems, and Feature-Aware Student knowledge Tracing (FAST) which is our new learner model proposed in 2014 with state-of-the-art predictive performance. We have also explored different aspects to improve learner modeling, including reducing the content model, better evaluation for practitioners and applying network (graph) analysis.

Recommendation

Personalization
There are multiple personalization approaches, that are developed and researched in our system. In the form of recommendations, we have various methods in different levels for recommending learning material to students. Two major approached for recommending resources are reactive and proactive recommendations. In the reactive approach, the recommender system activates in reaction to the student's activity, e.g. if the student fails in solving a quiz, the reactive recommender system recommends related examples to this student to help her understand the skills required to solve that quiz. The pro-active recommender system, proactively suggests learning materials to the students. ==> more


Educational Data Mining

Educational Data Mining
In this part of the project, we aim to make sense of data from Mastery Grids system, including logs of student attempts. The goal in this part includes understanding students' learning patterns and its relationship with students' behavioral traits, predicting students' performance, modeling student knowledge, and discovering the content model. These tasks eventually help us in providing a better service to both instructors and students. ==> more


Smart Content

Smart Content (Animated Examples)
Mastery Grids supports and provides multiple types of learning materials. It has been applied in three domains (Java, SQL, and Python) as a supplementary E-learning system for undergraduate and graduate level programming and database classes since 2013. We have developed different content applications (e.g., QuizJET, QuizPET, WebEx) and authoring tools (e.g., Content Authoring Tools, Course Authoring Tool, Group Authoring Tool) for accessing and authoring such contents. In each learning domain, courses are organized by topics and different types of learning contents are arranged under each topic. Learning contents contain problems (quizzes), parson problems, annotated examples, and animated examples collected from experienced course teachers, textbooks or domain experts. ==> more

Authoring Tools

Annotated Example Content Authoring
We have developed four major types of authoring tools for the project: 1) Content Authoring Tools for creating different kinds of smart learning content, 2) Course Authoring Tool for creating adaptive courses that use the content, 3) Group Authoring Tool for managing users and groups, as well as 4) the portal to access different authoring tools.
