A biased introduction to Learning Analytics: Kicking-off #UMNLACoP

Today, we kicked off our Learning Analytics Community of Practice at UMN (#UMNLACoP)! Launching this CoP has been a joint effort among the Center for Educational Innovation, the College of Liberal Arts, the Libraries, and the College of Education and Human Development.

The next event will be hosted on April 10, 2:30-4:00pm, in Anderson 110.
