Hi Margie: Most classes have a variety of students with a range of past learning abilities and current capabilities. Some instructors will use their stronger students to assit the waeker students, sort of like mentors or tutors. Other will separate the class into groups wth high, medium, lower performing students, then customize the assignment based on the "stregth" of the group. Same assignment, just differing level of engagement or difficulty of assignment. Also, having stronger students facilitate some portios of the class allows them the expression they need using the abilities they possess. Testing has has to be fair. Using essay-type questions can assist the teacher in being fair to all, especially if they use a grading rubric to award points. Regrads, Barry
