Reducing class size has traditionally been seen as an important way to improve a student’s educational experience. Many public opinion studies have shown that both teachers and parents favor smaller class sizes. Teachers who go on strike are often seeking lower classroom numbers, among other better working conditions. Many often believe that smaller classes would permit teachers to give more personal attention to their students. This can theoretically lead to improved academic results for students. But one recent study suggests there is not much research-based evidence to support this idea. The research was collected by a team from Denmark’s Danish Center for Social Science Research. Results were published by not-for-profit Campbell Collaboration, based in Oslo, Norway.
