HarvardX Adaptivity Bridge


About the 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 Project


HarvardX Adaptivity Project

The adaptivity evaluation project of HarvardX is an internal research initiative which aim is to measure the effectiveness of eLearning adaptivity.

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

The Solution

Adaptivity Bridge - The New Way to Implement Adaptivity

We've built LTI-compatible "Adaptivity Bridge" - The tool that connects LTI-compatible content sources, adaptivity engines and LMSs


Content Source Creation

Content sources are easily gathered from existing LTI-compatible courses for further connection with adaptivity engines and LMS


Connecting Content to Adaptivity Engine

Collections are easily gathered in groups and connected using various options to any LTI-compatible adaptivity engine


Adding Adaptive Content to LMS

Adaptive content is easily connected to LMS via LTI. We used LTI xBlock to connect adaptive assessments with edX

The Results

HarvardX Adaptivity Experiment Results

Adaptivity Bridge helped optimize adaptivity assessment experiment and bring the project to life. More on this in HarvardX blog posts by Yigal Rosen.
