Adapted from How to Grade for Learning (O'Connor, 2002)
This slide presents a case example as context for the grading don'ts presented on the previous slide. The case example, adapted from O'Connor, presents the scores of 3 students in a parachute packing course on 7 successive parachute packing tries. Each student's score out of 100 is presented for each packing attempt, and 60 out of 100 indicates mastery, or a guarantee that the parachute will open. Each student's 7 scores average out to 70, but their patterns look very different. Student A achieves mastery with a score of 95 on the first attempt, fails mastery with a 40 on the second attempt, and alternates mastery and failure each turn. Student B has very low scores for the first 3 attempts, but achieves mastery on the last 4 attempts, achieving a 95 on the last try. Student C achieves a 95 on the first attempt and high mastery scores on each of the next 3, but has very low scores for the last 3 attempts. Participants in the training session were asked to review this slide while answering the questions on the next slide.
