Digital learning objects (DLOs) are educational resources delivered online that can be used modularly and are reusable. They include presentations, web guides, screencasts, videos, lectures, quizzes and virtual exhibits. As online learning evolves, there will be greater participation from traditional universities, more hybrid courses, and curated open access DLOs that use mixed media. The future may also include gamified DLOs, integration of digital humanities tools like text mining and GIS, and students creating knowledge through DLOs.
