Ability grouping is an educational practice where students are divided into groups based on their skill levels or abilities in a particular subject. This method allows teachers to tailor instruction to meet the specific needs of each group, potentially enhancing learning outcomes. For example, students who excel in math may work together on advanced problems, while those needing more support can focus on foundational concepts. Critics of ability grouping argue that it can lead to social segregation and limit opportunities for collaboration among students of different abilities. They suggest that mixed-ability classrooms, where students learn together, can promote inclusivity and help all students develop a broader range of skills.
