CTAT icon

The Cognitive Tutor Authoring Tools (CTAT), is a tool suite that enables you to add learning by doing (i.e., active learning) to online courses. CTAT supports the creation of flexible tutors for both simple and complex problem solving, capable of supporting multiple strategies that students may draw on when solving tutor problems. CTAT tutors track students as they work through problems and provide context-sensitive, just-in-time help.

The DANCE discussion forum XBlock represents a first step towards improving scripted support for collaboration in MOOCs. The XBlock provides all basic features expected of a forum while augmenting the experience with social recommendation (that as an example recommendation application matches help seekers with help givers). It provides light social awareness and semi-synchronous interaction through a Personal Messaging capability. It also provides the forum data in a source agnostic data infrastructure model using DiscourseDB (see below) that will allow the contextualization and comparison of discourse data from across platforms.

Bazaar is a publicly available architecture for orchestrating conversational agent based support for group learning. It is a powerful tool for facilitating research in collaborative learning. It hosts a library of reusable behavioral components that each trigger a simple form of support. More complex supportive interventions are constructed by orchestrating multiple simple behaviors. Its flexibility and simplicity mean it can be used to very rapidly develop platforms for investigating a wide range of important questions within the design space of dynamic support for collaborative learning.
