Accelerated Reader, or AR, is a software program that tests students on what they learned from a book. It is a great way for students to improve themselves because the tests give detailed results of questions answered incorrectly. It also helps the teacher because it can be another source of information about students' strengths and weaknesses.
The way it works is simple. Students choose and read a book (it might be a good idea for them to check and see if the book is in the AR archive). After they read, they log onto AR and sign in under their name. They choose the book they read and take the quiz (which specs can be adjusted for what is considered a passing score, how many times the student can retake the quiz, and so on).
In order for it to be successful, the teacher needs an extensive classroom library, because the AR software does not have quizzes on every book. AR also gives another great alternative for something to do at DEAR and SSR time (click on the links to the left to learn more about them).
