While I no longer have any classes that meet on Blackboard, when I was an undergraduate student at U of I I had several classes that used Blackboard Learn as the platform where online discussions were had and assignments were turned in. At the time, your grades would be posted as a simple grade much like they are on learn.illinois.edu now. However, by watching the link and video below you can see that Blackboard has added a new analytics feature. Much like the feature we have here in Scholar, the system tracks the details of student's grades. While it does track each individual area of a student's performance (if a professor decides to break the areas of weight down), it also tracks performance over time in those categories and makes reports available to both students and teachers. Blackboard argues the reason for these tools additions were for dual purposes. Firstly, it makes students more successful because "Research conducted by John Fritz (2013) at the University of Maryland Baltimore County has shown that giving students information about their activity compared to others significantly increases their course performance.By having these analytics tools students can be more successful because they are able to track their grades better. Also, instructors get a "better, faster way to get the information they need to help their students and keep them on track" (Blackboard Learn, 2019).
