In which setting would a student with Down's syndrome and ADHD be least effectively seated?

A student with Down's syndrome and ADHD typically requires a learning environment that minimizes distractions and allows for close monitoring and support. Being seated near a window facing the playground can lead to significant distractions. The visual stimuli from outside, such as other children playing, can divert the student's attention away from instruction, making it difficult for them to focus on the lesson.

In contrast, placements like sitting close to the teacher's desk provide immediate access to guidance and intervention, while quieter areas of the classroom can help reduce sensory overload and promote concentration. Therefore, positioning a student in such a way that they are prone to visual distractions would be the least effective seating arrangement for their educational needs.
