One challenge I have is working with students that have not been exposed to the prerequisites of a class I am teaching. I can not stop the class to help them catch up because that will only diminish the experience for students prepared for the class.
I have been working with students that are not prepared, providing them opportunities for tutoring and giving them websites I feel will help them catch up.
It is still a challenge to get some students to push themselves to catch up to the point they need to be at.
What are your thoughts on this problem?
