-Text -Images -Movies -Animation -Sound -User Control Elements In most cases, a combination of two or more elements provides the best results

-Ability of the user to interact with an application Fundamental Feature Interactivity: -Ability of the user to interact with an application -Content presented in a nonlinear way -User is active rather than passive User determines: -the content that is delivered, -when it is delivered, -how it is delivered

Interactivity comes in many forms: -Keyboard input How does user control? Interactivity comes in many forms: -Keyboard input -Mouse point-and-click -Mouse rollovers -Voice activation -Touch screens

Fundamental to Multimedia -Computer system -Must be capable of showing the multimedia elements -Sound and animation (often a problem) -CD-ROM/DVD Drive -Speakers/headphones -Audio card -Graphics card -Internet -Sufficient speed and processing power to deliver multimedia

A multimedia program is designed to support the learning process. Why use Multimedia for teaching? A multimedia program is designed to support the learning process. Multimedia offers the experience of listening, looking and doing in a computer-mediated setting. It can be interesting, motivating, exciting and help students achieve understanding in new ways.

There is also a high level of interaction. The use of sound, photographs and video enables the user to observe real world situations which is just not possible with the more conventional methods of instruction. There is also a high level of interaction. Most packages expect students to make choices about what they want to do next and the way in which they wish to work through the material. They are not passive but expect learners to actively participate.

Design - Basic Features The multimedia package has to incorporate the following control features into its interface: 1. A structured logical content map to allow the student to access all information. 2. Students need the freedom to control the sequence in which they encounter information and to set their own learning "goals". To this end the program should clearly display a list of objectives - what the students are expected to learn. This also makes the user aware that they have achieved them. 3. Meaningful feedback - both intrinsic and extrinsic 4. Frequent questioning to offer the user the opportunity to test their conception of the topic. 5. A form of record keeping of student actions. This can be used for computer-based assessment.
