Accommodations effectively adapt to student difference and abilities. It gives high-achieving learners an opportunity to explore further, and low-achieving students more direction. Low achieving students are more likely to succeed, while high achieving students have more time to expand their mind and participate in extra activities.
Constantly trying to accommodate for multiple levels of students will result in less poignant lessons where the only opportunity to dive deeper into a subject is given to the high-achieving learners.
Because the teacher is focusing all his instruction time on low-achieving learners, he becomes an enabler.
Constantly providing lesson variety and extra opportunities, while trying to meet the needs of all students will overwork the teacher, and create ineffective lessons.
