My mother was a teacher in rural Michigan from the 1930s through the 1960s. She taught in multi-grade classrooms throughout her career. In fact, in the 1930s she taught in one-room schools, grades one through eight.
She felt the key to effective teaching was class size, not number of grades in the class. The number of students she had in a given year usually numbered about 25. When the number of students exceeded 30, she felt she couldn’t do a good job.
I was in multi-grade classrooms from grades one through six. I never thought it hindered my academic achievement (M.A., University of Michigan, 1973). Of course, my parents were very supportive of my educational endeavors — in particular my mother.
I can understand why parents who were never exposed to multi-grade classrooms might be concerned. It is the Board of Education’s responsibility to reasonably and rationally allay those fears.
For what it’s worth, I am writing to reassure you, it’s not a big deal.
