In January 1919 a 50-foot molasses tank burst in Boston’s North End and a wave moving at about 35 mph killed 21 people.
The papers called it an explosion and the owners blamed a bomb; the tank’s steel tells a different story.

In You Can See Everything, Nathan Fielder sets his reality-distorting comedic documentarian talents on disgraced tech founder Elizabeth Holmes. The movie had the internet in a chokehold even before its release. Are there lessons in Fielder’s theater of the awkward and the cringe comedy genre for traditional journalism?

Presented at #OpenEd, November 13th, 2020
Tanya Joosten & Kate Lee-McCarthy

The Digital Learning Innovation Trends report identifies the most prominent trends in digital learning. The report, published in 2020 by OLC and DETA, stemmed from the Every Learner Everywhere Network and its initiatives. It was developed using OLC Digital Learning Innovation Award submissions plus a review of documents produced by industry leaders, national organizations advancing technology in learning, journals and peer-reviewed research, news and media sources, and prominent research centers. While research indicates that OER is one of the top trends in digital learning, the findings about open resources are not exactly what one would expect.

To maximize the potential of OER to support digital learning, it is important to examine not just existing implementation and utilization, but to empirically link these initiatives with student success. Combining our expertise and experiences, we can better identify effective actions as well as gaps in research and practice to shape a better digital learning experience and support more students in their learning endeavors. Further, reaching others through our research can propel technology development and utilization, as well as further advance OER integration with active learning platforms.

Watch our lightning talk highlighting the Trends Report, the surprise findings about OER, and get insider information and preliminary results on more empirical research on OER that the same teams are working on today. In this session you’ll hear from some of the top leaders in the space and gain knowledge about why OER trended, what the concerns are regarding current research (including equity and the close ties there are to OER), and our proposed next steps plus recommendations to propel this fantastic resource further into practical implementation at institutions and learning environments.

Learning Outcomes: 5 Learning Outcomes of OER & the Digital Learning Innovation Trends Report:

1) Introduction to the Digital Learning Innovations Trends report
2) Understand how OER was identified as a primary trend
3) Learn about surprising OER findings in relation to the report
4) Understand continued empirical research being done on OER
5) Identify proposed next steps and recommendations for OER implementation and use

Director, Digital Learning R&D and DETA Center, University of Wisconsin-Milwaukee
