In 2005, three PayPal employees joined together to launch "YouTube." Since then, this website featuring videos about any topic has grown in fame and popularity by allowing people to upload their own videos and
share information in a new way. It's clear that people can use this site for entertainment, but what about education? YouTube has several uses in classrooms and at home, a key point made by researcher Marc
Prensky. In his paper "Why YouTube Matters," he makes several important points, including the increased communication possibilities, tutorial videos, as well as deeper information.
If you're interested in Prensky's work,here is a link to the report.
Or, if you would rather see if for yourself, check out Khan Academy, featuring tutorial videos about a variety of topics.
