Davina,
I thinks as much as providing the best instruction, a good instructor will manage to find time to share grade and performance status to students. Like a road map to a destination, sharing class performance states where the student is in comparison to where we want them to arrive when the course completes. If we do this with sincerity, frequently, and early on, students will benefit and appreciate the effeort and time, and perhaps reinforce trust and respect for the instructor.
