The Purpose of Accelerated Reader: Powerful Practice Reading is a skill, and like every skill it requires not just instruction but practice. Reading practice enables students to apply the skills and strategies that you teach. It gives you opportunities to check student learning and identify weaknesses. And it draws students into the world of “real” reading—a world in which people learn from and enjoy books. Practice does not automatically lead to growth, however. To be effective, practice must have certain attributes: it must be at the right level of difficulty, cover a sufficient amount of time, be guided by the instructor, and be enjoyable enough to sustain.
