Eric Kean develops iPhone app for pre-calculus learning

Eric Kean, a lecturer of mathematics in the College of Sciences and Technology at Western Washington University, has developed an educational pre-calculus app for the iPhone, iPad and iTouch.

The app has 500 pre-caclulus-related questions and answers in the form of flashcards and more than 200 audio tips to help students better understand the solutions. Kean is currently working on two more apps: one for high school AP Statistics and another for an introductory, university-level statistics course.
