Multimedia helps the user become more engaged with what they're learning by using multiple different methods to engage the user. When the user is interested or is engaged with his/her work, what he/she is learning becomes more enjoyable allowing the information to stick.
Explanation:
Multimedia is one of the many ways of communicating. It combines many different things including audio, animation, or text, all together which allows the user to interact with these different learning methods and become more interested, because it tries many different learning techniques at once.
A common example of multimedia would be websites such as ABC mouse.com, which allows the user to interact head on with the lessons while using many different things to help the student become more engaged with what they're learning. Things such as mini games, points to earn to buy items, and in-lesson interaction with multiple choice questions. All help the student become engaged/addicted to using the website.
To sum up, how can a classroom be more effective by the use of multimedia? "Multimedia helps the user become more engaged with what they're learning by using multiple different methods to engage the user. When the user is interested or is engaged with his/her work, what he/she is learning becomes more enjoyable allowing the information to stick."
