S3xE2: Alternative grading, how?

The CS-Ed Podcast

In part two of our episode series with Kevin Lin and Brett Wortzman from the University of Washington, we dig into the details of how they implement their alternative grading systems. Brett outlines their ESNU system that stands for exemplary, satisfactory, not yet and unaccessible, as well as the components of his grading system for his large CS1 course, and Kevin talks about his version from his CS2 and other data structures courses. We discuss trading off complexity for precision and how much differentiation in grades is actually feasible and necessary. We also talk about grading workload and balancing the convenience of autograding with the depth of feedback from manual grading. Kevin emphasizes how grading “bundles” can provide more clarity for students on what the expectations are for each grade. Finally, both Kevin and Brett emphasize considering constraints, priorities, and tradeoffs in choosing a grading system for your own class. If you haven’t yet, consider listening to the first episode of the series on why to consider alternative grading and the potential systems to choose from!
