World class repository
of education data.

LearnSphere integrates existing and new educational data and analysis repositories to offer the world's largest learning analytics infrastructure with methods, linked data, and portal access to relevant resources.

Data-driven course design

LearnSphere enables new opportunities for learning education researchers, course developers, and instructors to better evaluate causal claims, leading to improved teaching and learning. This data-driven course redesign is possible both through better analytics of relational data and through online platform support of controlled experimentation.

Large distributed data infrastructure

LearnSphere facilitates a distributed method of data storage and access control. LearnSphere offers a central portal for the sharing, storage, and analysis of public and private datasets. For private datasets, a local storage option allows researchers to share tools and results while maintaining ownership of their data.

Analytics sharing & use

A standard set of analysis tools allows researchers to quickly start gathering information. Users can also leverage user-contributed workflows and tools to perform other methods of analysis on their data. Using a community based tool repository, researchers are able to quickly build new models, create derivative works, or improve existing tools and share their work with their team or the whole world.

New version of Tigris released! (11/07/17)
With this release we continue to extend the functionality of the LearnSphere workflow tool, as well as enhance it's usability. A focus of this release has been adding support that facilitated the creation of many new components. Continue reading...

Current Resources

The LearnLab DataShop is a data repository and web application for learning science researchers. It provides secure data storage as well as an array of analysis and visualization tools available through a web-based interface. DataShop was funded by a National Science Foundation grants (SBE-0836012, SBE-0354420) to LearnLab.

The MOOCdb project aims to brings together education researchers, computer science researchers, machine learning researchers, technologists, database and big data experts to advance MOOC data science. The project founded at MIT includes a platform agnostic functional data model for data exhaust from MOOCs, a collaborative-open source-open access data visualization framework, a crowd sourced knowledge discovery framework and a privacy preserving software framework. The team is currently working to release a number of these tools and frameworks as open source.

DataStage is provided by the Vice Provost Office for Online Learning (VPOL) at Stanford, which facilitates the teaching of online classes. The instruction delivery platforms are instrumented to collect a variety of data around participants' interaction with the study material. Examples are participants manipulating video players as they view portions of a class, solution submissions to problem sets, uses of the online forum available for some classes, peer grading activities, and some demographic data. VPOL makes some of this data available for research on learning processes, and for explorations into improving instruction through Datastage.

DiscourseDB is a data infrastructure project, in the space of collaborative and Discussion-based learning, that aims to provide a common data model to accommodate diverse sources including but not limited to Chat, Threaded Discussions, Blogs, Twitter, Wikis and Text messaging. In the future, the project will make available analytics which will facilitate research questions related to the mediating and moderating effects of role taking, help exchange, collaborative knowledge construction and others.

Tigris is a workflow authoring tool which is part of the community software infrastructure being built for the LearnSphere project. The platform will provide a way to create custom analyses and interact with new as well as existing data formats and repositories, such as DataShop, MOOCdb, DiscourseDB and DataStage.
