Confidence-based marking is a way to encourage students to think about how confident they are with their answer to a question. Positive and negative marking is used to award more marks for correct answers given with confidence and less marks for incorrect marks with a high degree of confidence that the answer was correct.
Gill Harrison from the division of Radiography and Midwifery explains how she uses confidence-based marking in class and within Moodle to encourage student self-assessment of their diagnostic skills.
