I am a fan of the Kahn Academy web site, which leverages YouTube to provide over 2100 tutorial videos on subjects like Algebra, Biology, Economics, and Astronomy. The videos are free, run about five to ten minutes each, and can be played on smartphones and tablets. While you can pause, rewind, and otherwise play the videos over if you did not understand something, they don’t provide for direct interaction with an instructor. Motuto is an on-demand, real-time mobile tutoring app that directly addresses some of the limitations of the Kahn Academy.
Motuto currently runs on the iPad and iPhone, and is being developed for Android. Users first set up a profile that specifies their grade level, which is used to match them with a tutor. When you start the app you specify what subject you need help with, and enter a chat room where a tutor is available to answer questions. The chat room is combined with a shared whiteboard so that the tutor and pupil can interact with each other, and pupils can upload a picture of the specific problem they may be working on.
When the session is done Motuto sends the pupil a recording of the session that they can replay for further review or future reference. Currently Motuto is free for a limited time, afterwords 20 minute sessions will cost $4.99. If you need to extend a session each additional 20 minutes costs $1.99. Motuto is currently available to provide tutoring from 11 AM to 11 PM Pacific Time, 2 PM to 2 AM Eastern, Monday thru Friday, but the service plans to expand their availability to 24 hours, 7 days a week.
The Motuto app is free and available in the iTunes App Store.
