Class sizes kept to a reasonably manageable number of students can help to increase the amount of time a teacher is able to spend individually with a student, while decreasing the amount of time spent on addressing classroom disruptions. This can help to promote increased student achievement, especially for students from disadvantaged backgrounds. Additionally, allowing students adequate space in the classroom can be a strategy to keep learning spaces from becoming spaces of stress, and instead represent spaces conducive to focus, productive collaboration and creative thinking.
