Each student comes to the classroom with a unique profile of abilities, knowledge and interests. Some do better when they can first try to figure things out on their own; others do better when a teacher can first provide an explanation. Some do best when they learn in groups; others do best with technology. Some are far ahead of grade level material; others are behind.
In today's classrooms, it's just too hard for teachers to craft an educational experience that meets each student's unique needs—even though there is a large and growing amount of high-quality digital and live educational content available online and from publishers. Developing an individualized plan to meet each student's needs each day is unrealistic, even for our best teachers.
