What is the DataShop?

The DataShop is a data analysis service for the learning science community. It is both a central repository for research data and a suite of tools to analyze that data.

The PSLC DataShop provides two main services:

  • secure storage of log data that is generated during in vivo experiments
  • relevant statistical analyses and reports that are based on those data

Data collection and retrieval is a three-stage process:

  1. raw data logs are collected either in real-time or after the study;
  2. data are extracted, anonymized, and stored in an analysis database
  3. reports and queries are rendered via the web upon request

After authenticating on the DataShop website, researchers can rapidly access standard reports such as learning curves, as well as browse data using the interactive web application. To support other analyses, the DataShop can export data to a variety of formats that can then be used in statistical software and other analysis packages.
