Which of the following is considered an example of exclusion?

Exclusion in an educational context refers to practices or policies that prevent certain students from participating fully in learning opportunities. Asking for social security numbers can act as a form of exclusion, particularly if it is used as a barrier to access or if students do not have such numbers due to their immigration status or other circumstances. This requirement can lead to students feeling marginalized or being excluded from important processes, such as enrollment or receiving necessary support services.

In contrast, the other options promote inclusion and participation. Performing group projects encourages collaboration among students, fostering communication and teamwork skills. Encouraging bilingual education supports students' linguistic and cultural backgrounds, promoting an inclusive environment where diverse languages are valued. Utilizing graphic organizers aids all learners by providing visual frameworks to understand complex information, thus enhancing learning for everyone.
