People retain only 20% of what they see and 30% of what they hear. But they remember 50% of what they see and hear, and as much as 80% of what they see, hear, and do simultaneously. When we incorporate multimedia into an application, more of our senses are activated. Consequently, one reason to use multimedia is to give life to flat information (Hofstetter, 1995).
Multimedia can be used to encourage constructivism. Constructivism is a philosophy of learning holding that students interact with real-life experience that surrounds them. This premise contrasts to behaviorism which perceives the teacher as the manipulator of an environment that is experienced by the learners.
Chinese Proverb ...
“Tell me and I will forget; show me and I may remember; involve me and I will understand.”
CAI (computer assisted instruction) is popular use of multimedia in education. The applications include:
• Tutorial
• Drill and Practice
• Simulation
• Games
• Discovery
• Problem solving
• Test
World Wide Web
Today the Internet is recognized as a powerful tool for development. The world wide web is the complete set of documents residing on all Internet servers that use the HTTP (hypertext transfer) protocol, accessible to users via a simple point-and-click system (answer.com, February 2007). Therefore multimedia can be completely integrated to the world wide web and promote the use of the Internet for development at all levels.
