between the learner and lesson content, help learners find and organize information, and facilitate lesson navigation. 2 Interaction and Feedback The key of interaction and feedback is the availability of control, stimulus and response in the multimedia. It is expected that learners can have control of the flow of the information in the multimedia. Furthermore, a good interact ive multimedia has to be able to give reaction to the actions learners’ done in the multimedia, as well as stimulating learners’ curiosity. 3 Navigation Navigations supposed to be less complicated and enhance learning process. There are buttons to move to a particular frame or scene, and the placement of the buttons has to be consistent. 4 Learner control A good interactive multimedia will enable learner to choose the learning materials, level of difficulty, exercises, and practices due to their need and interest. But, the portion of the control has to be suited to the characteristics of the students. Older students may learn more efficiently with bigger control, but younger students and low ability students may get confused instead. 5 Color Color is most effective when used consistently for cueing and highlighting. Effective colors should use a maximum three to six colors per screen, use the brightest colors for the most important information, use a neutral colors as a background and use significant contrast between text and a background color to provide a higher degree of text readability. Avoid using hot colors and complimentary colors. 6 Graphic It is better to use both text mode and graphic mode rather than just text mode or graphic mode alone. 7 Animation Animation in a good interactive multimedia has to be able to make clear the materials, as well as motivating, and attractive. 8 Audio The use of audio in the interactive multimedia has to be able to be controlled by the user. The audio has also to make clear information related to the materials. In addition, Newby 2000 consider that there are some criteria of effective interactive multimedia design, which are: 1 Graphics: effective graphics should eliminate distracting background and use visual that are neither too abstract nor too realistic. 2 Texts: effective texts should put title at centre top of visual, use short, concise, meaningful, descriptive titles, that contain key words, eliminate unnecessary words, use italics, boldface, underlining, color or a change in learning style for emphasize, and minimize text on each visual. 3 Colors: effective colors should use lightest and brightest colors to focus attention on important elements, use lettering and visual that contrast with background colors, select colors that are harmonious, use consistent background colors in a series of visual, and limiting the number of colors in a visual to five. 4 Layout: effective layout should make visuals as simple as possible, use size, relationship, perspective, and such visual tool as color and space to emphasize important elements, and use pleasing layout that appears balanced and orderly. 5 Videos: effective videos should have clear and appropriate visualization to the theme and have clear sounds. In line with that, Smaldino et al. 2014: 203 stated that students and teacher supposed to use the following materials to produce appropriate media: 1 Text: up to 10 or 1,000 words, whichever is less. 2 Audio: up to 10, but no more than 30 seconds, provided the excerpt does not compromise a part of the whole that would constitute a performable unit such as a section, movement, or area. 3 Images: not more than 5 images by the same artist or photographer and up to 10, but not more than 15 images from a single collection.
