More time for teaching and learning, and more space in which to do so. A greater ability to monitor and evaluate their students. An enhanced atmosphere that leads to tailored instruction at each student's ability level. More time to assist individual students in a relaxed, interactive environment. A reduction in class size doesn't automatically ensure that classrooms will be characterized by these elements.
Many people seem to assume so, but the research offers little guidance.
Instead of focusing on specific teaching techniques that work best in smaller classes, most studies look at effective teaching practices in general and examine whether teachers engage in more of these practices in smaller classes. Smaller class size may simply enhance the instructional strategies already employed by effective teachers. Bohrnstedt and Stecher recommend that school officials pay careful attention to teaching practices in small classes so they can design professional-development programs to equip teachers with suitable new skills. Instruction is guided by a preplanned curriculum. Students are carefully oriented to lessons.
