Which of the following is NOT a type of grouping mentioned?

Fixed grouping is not typically recognized as a standard type of grouping used in educational settings. In contrast to other types of grouping, such as ability grouping, performance grouping, and interest grouping, which are commonly employed to differentiate instruction based on specific student characteristics or needs, fixed grouping implies a static arrangement that does not adapt or change based on student progress or development.

Ability grouping organizes students based on their skill levels in a particular subject, allowing for instruction that is tailored to their needs. Performance grouping focuses on students' current achievements and can change more frequently based on their progress. Interest grouping centers around students' personal interests, facilitating engagement in learning.

In contrast, fixed grouping can lead to a less flexible approach, potentially limiting students' opportunities for growth, exploration, and collaboration with peers who possess varying skills and interests.
