Grades should provide feedback to students, parents, and teachers as to the progress students are making toward learning targets. Meaningful grades require good assessment practices. Erica Posthuma presented a ChemEd X Talk on May 11th, 2021, providing an overview of effective assessment design. She discussed writing and communicating learning goals, developing targeted questions and prompts, and scoring using a standards-based approach. You can watch the edited recording of Erica's Talk below.

Thanks for sharing this talk, Erica. I agree that the purpose of grading is to COMMUNICATE student achievement. You are probably already familiar with Ken O'Connor's work. I've enjoyed reading Ken's book about fixes for grading.
