Malena A: “I invite Romney to spend one whole week in my class (8-2:30) with 38 sixth graders and then we'll see if class size matters.”

Melissa H: “I can't tell you how hectic, stressful, and inefficient a large-size classroom is.”

Rebecca M: “Oversized classrooms are not fair. They are not fair to teachers, students, or everyone's future.”

Colleen F: “The larger the class is, the easier students get distracted and do not pay attention.”

Sarah P: “Class sizes matter when I have 35 students all with different levels of ability and different special needs.”
