How can Alicia's teacher most effectively change her behavior regarding the beanbag chair?

The most effective approach for changing Alicia's behavior regarding the beanbag chair involves modeling turn-taking and closely monitoring her interactions. This option emphasizes direct engagement with Alicia's behavior by providing her a practical demonstration of appropriate actions in a social setting. By modeling turn-taking, the teacher demonstrates the expected behavior, making it clear what is required in order to use the beanbag chair effectively.

Close monitoring is crucial here since it allows the teacher to provide immediate feedback and reinforcement as Alicia learns to appropriately share and take turns using the beanbag chair. This type of proactive teaching strategy not only helps Alicia understand the concept of sharing but also supports her in developing social skills, ensuring that she feels guided and supported in her learning process.

In contrast, simply telling the students they may not use the center (the first option) does not provide them with the skills they need to behave appropriately and can create an adversarial atmosphere. Holding a class discussion about rules (the second option), while informative, may not provide the specific direct instruction and modeling Alicia needs to change her behavior effectively. Allowing children to resolve the problem themselves (the last option) may promote student agency, but it risks not addressing Alicia's specific behavioral needs directly and may prolong the issue without structured guidance.
