This post builds on analyses of two use cases by Barbara Means of SRI. One case describes the testing of a multimedia intervention in a college-level course. The other case describes course redesign using longitudinal data analysis.
Drawing on these two cases, I propose some new approaches to design-based research, including increased collaboration through shared design and data repositories. I seek feedback on these nascent analyses, and welcome similar cross-case analyses using these and other use cases. READ MORE
Challenge: Provide best learning approach for each student
Stakeholders: Researchers, Developers, Teachers, Students

Methods: A/B Testing; Learning Analytics
Author: Barbara Means based on an interview with Ken Koedinger and references below.
The Challenge: Researchers at LearnLab, the Pittsburgh Science of Learning Center, set out to see whether they could improve the effectiveness of an online chemistry course by applying design principles based on research. Within a chemistry course developed by Carnegie Mellon University’s Open Learning Initiative (OLI), they identified the portion that deals with equilibrium as being particularly challenging for students.
