What is 'group fragmentation' intended to support?

Group fragmentation is intended to support smooth transitions during activities. This concept refers to breaking larger groups into smaller, manageable segments to facilitate better interactions and transitions among students. When activities require different formats or groups, employing fragmentation allows for quicker adjustments and adaptations, thereby enhancing collaboration and the overall flow of classroom instruction. This method can help maintain student engagement, as smaller groups often allow for increased participation and connection among peers, making transitions less disruptive and more effective.

In the context of the other options, while individual tests and examinations, segregating students based on performance, and classroom decoration and arrangement have their own merits in educational settings, they do not align with the primary goal of group fragmentation, which focuses on promoting effective transitions and collaboration rather than dividing or assessing students.
