Mastery Grids is an open social learner modeling interface written in Javascript. The interface shows the student's progress or knowledge in topics or content types comparing with other learners, and provides navigation support to access suitable educational content.

Contents

Open Social Learner Model

Mastery Grids is our latest implementation of open learner modeling built based on our past successful systems (e.g., InterBook, QuizGuide, NavEx, QuizMap, Progressor). Combining open learner model with social comparison, i.e., open social learner model, Mastery Grids not only enables a student to be aware of the strength and weakness among his/her own knowledge modules, but also stimulates students to work harder. Our open social learner model encourages students to catch up with other students (observing average class progress or advanced students’ progress) and follow the potential good learning path of the peers.

Knowledge and Progress Visualization

Mastery Grids presents and compares user learning progress and knowledge level (mastery) by colored grids from four perspectives as shown in the following figure. The four perspectives show the current student’s progress (“Me” or my progress), a comparison of performance of current student versus other student in the group (“Me vs group” or comparison grid), performance of the students in the group (“Group” or group grid), and performance of all of the students in the class.

Social Comparison

Social comparison is implemented in two ways: 1) Me vs group, which compares an individual learner’s progress or knowledge level with the entire group of students, and 2) Me vs other students, which compares an an individual learner’s progress or knowledge level with each of other students. Such comparisons can be further conducted by resource types (learning materials) as shown in following figure.

Adaptive Navigation Support

Mastery Grids also provides adaptive navigation support for learning materials (as shown in following figure with stars indicating the recommendations). It tracks user activities and updates student knowledge level in a centralized user modeling server, and thus can report in both progress level (based on activities) and knowledge level (based on estimated user knowledge). It provides flexible user-centered navigation across different content levels (e.g. topic, each content type) and different content types (e.g. problem, animated example) and tracks user feedbacks on recommendations dynamically. Details of user modeling can be found here. Details of the personalization (recommendation) can be found here.
