The Roles of Instructional Media in the Teaching Learning Process

3 Instructional appropriateness It includes three main points, which are: a the appropriateness of media for the planned instructional strategy; b the efficiency and effectiveness manner offered by the media; c whether the media will facilitate the students acquisition of specific learning objective or not.

6. Interactive Multimedia

a. The Definition

Richards and Schmidt 2002: 345 explain multimedia as the use of several different types of media for a single purpose, e.g. as in a video that uses film, audio, sound effects, and graphic images. They also add that multimedia is a collection of computer controlled or computer mediated technologies that enables people to access and use data in a variety of forms: text, sound, and still and moving images. Vaughan 2008: 1 says that multimedia becomes interactive when the users of multimedia application can control what and when some parts of the application contents will be delivered. Added to this, lesson on CAI Computer-Assisted Instruction materials may involve a question on the computer, a response from students, the feedback from computer telling the students if the answer is “correct”. In CAI, such activities are said to be “interactive” Richards and Schmidt, 2002: 265

b. Principles of Interactive Learning Multimedia

To design interactive learning multimedia, we have to take into account seven basic principles of interactive multimedia as recommended by Mayer 2005: 6-7. The following is the list of the principles. a Multimedia principle: Students learn better from combination of words and graphics than from word alone. b Split-attention principle: Students learn better when the corresponding words and graphics are placed closely to one another than separately. c Modality principle: Students learn better from graphics and narrations than graphics and printed texts. d Redundancy principle: Students learn better when the same information is not presented in more than one format. e Segmenting, pre-training and modality principles: Students learn better when a multimedia message is presented in learned-paced segments rather than as a continuous unit, students know the name and characteristics of the main concepts and the words are spoken rather than written. f Coherence, signalling, spatial contiguity, temporal contiguity and redundancy principle: Students learn better when an extraneous material is excluded rather than included, when cues are added that highlight the organization of essential material, when corresponding words and pictures are presented near rather than far from each other on the screen or page or time and students learn better from graphics and narrations than from graphics, narration and on-screen text. g Personalization, voice and image principles: Students learn better when the words of a multimedia presentation are in conventional style rather than formal style and when words are spoken in a standard-accented human voice rather than a machine voice or foreign-accented human voice; but students do not necessarily learn better when the speaker’s image is on the screen.

c. Elements of Interactive Learning Multimedia

The effective interactive learning multimedia should contain some elements that enable both teachers and learners to use it easily and effectively. Ivers and Baron 2010: 112 describe the main elements which make up a typical multimedia program. Those are as follows.
