Many people around the world are the owners of mobile, hand held devices. When thinking of these mobile devices and interworking them into school, the ideas of advantages does not come to mind. The advantages could be as simple as recording a performance or lecture. The audio can be used like e-books, where you are able to read your own books electronically. This will also allow you to help share documents. With the mobile devices it’s also possible to use references like a dictionary, thesaurus, and Wikipedia. Due to advanced technology, the internet is also on most mobile devices allowing you to review notes, study, and quiz yourself. Instead of having your notes and things scattered around it will all be organized inside of the mobile device. A great disadvantage would be that if the mobile device is lost, all of the information stored on it will be lost as well unless there is a back-up. Another disadvantage is not being able to work the mobile device and the different operations are not being carried out.
