Over time I have struggled with motivating timeliness in students submitting work. Many approaches involve some kind of reduction in the score earned: no credit at all, 25% off, 10% off per week late, etc. Students view these approaches as punitive, and I have had many students react negatively to such approaches. A few years ago, I started scoring multiple facets on assignments, such as giving scores for content and quality, format and mechanics, and timeliness. This way a student is always earning a score (a positive effect), not being punished for being late (a negative effect). Since instituting this approach, I have not received a single complaint about unfairness in scoring timeliness.
