Accelerated Reader or AR
Accelerated Reader is a software tool that assesses a student's reading level, suggests titles of books at that level, and then assess whether a student has completed reading the book by asking a series of questions. The software provides information to students regarding reading rates, amount of reading, and other factors related to reading.
There are three steps to using Accelerated Reader. First, students choose and read a fiction or non-fiction book, textbook, or magazine. Teachers monitor the reading. Second, students take a quiz. Teachers can create their own quizzes. Third, the teacher receives information that is intended to assist, motivate reading, monitor progress, and target instruction. Reports regarding reading level and comprehension skills are available through the software
