Adaptivity Bridge for HarvardX - Raccoon Gang Case Study

HarvardX Adaptivity Bridge

The Project

HarvardX Adaptivity Project

HarvardX is a University-wide strategic initiative to create open online learning experiences, and to enable groundbreaking research in online pedagogies. Adaptivity Bridge is a part of HarvardX's adaptivity effectiveness experiment.

The Challenge

Adaptivity Implementation Limitations and Complexities

Realization of learning adaptivity and further effectiveness analysis can be highly time/effort consuming.
For example, implementation of content delivery adaptivity requires a lot of investments:
- instructional designer(s) time to prepare materials for different learning paths, different content preferences, etс
- funds that are needed to resolve technical problems:
- selection and adoption of adaptive engines
- synchronization of adaptive engines, content and problem sources, learning management system, internal HR/student register systems etc

Raccoon Gang partnered with Harvard to simplify and optimize the process. So following tasks were set.

Simplifying Adaptivity Implementation

1 Ability to use multiple sources of learning content

The task was to create universal interface that gives the ability to use different sources of learning content that can be used for further usage by adaptivity engine.
2 Ability to change/add adaptivity engine

The interface needed to be able to connect to any adaptivity engine that is LTI compatible. That was intended to save a lot of resources compared to current situation where content sources cannot be connected to adaptivity engine without additional effort.
3 Ability to change/add LMS

Current situation is that additional effort needed to connect LMS with adaptivity engine that is tied to some content source (that is single and editable only with additional effort of third-party, again). The task was to enable the new interface to connect easy-to-change content sources and adaptivity engines
4 Adaptivity Bridge - tweak adaptivity with ease

As a result we needed to have Adaptivity Bridge - the interface that is able to connect various LMSs, content sources and adaptivity engines, change/add any of them in several clicks.
