Any combination of text, graphics, art, sound, animation, and video are considered multimedia. Often there are links and tools that allow the educator and/or the student to navigate, interact, and communicate with the computer.
Interactive Multimedia is the term used when the viewer is allowed to control what and when components of the presentation are delivered.Being a novice to technological applications in education, I feel that it is rather challenging to determine and understand how each element works together and how to apply these very same elements in a manner that has educational relevance.

I have found that YouTube has come a long way from simply staring at a computer screen. Here is an example of an interactive activity where users are encouraged to interact by clicking on links embedded within the videos.

COOL!!!

I also try to incorporate multimedia application in my Math lessons to allow opportunities for students to engage in activities that will solidify their knowledge.
