Rachel Tustin on 12 Dec 09The multimedia application on this website adequately addresses the learner centered approach in its design. It does so in a number of ways, in particular in how it allows the learner to manipulate the multimedia application and then represents the outcome of that manipulation in the form of a cartoon video. Mayer held that the brain possesses dual channels, an auditory and visual processor, and each processes the information separately, later merging these two experiences together to create knowledge (Mayer, 2009, p. 64). This multimedia site works on both aspects of knowledge building in that it includes both and auditory and visual graphics. However, once the introduction is completed the auditory component does not contain any content related information so the user can chose to mute the sound (Mayer, 2009, p. 64). The strength of this multimedia is that it allows the user to manipulate the video itself. For example, students chose a gas, and then select its level in the atmosphere (high-medium-low). From there, the multimedia video plays and shows them in about a thirty second video what would happen on earth in an accelerated time progression in order for students to see the impact the gases have on the atmosphere. However, it is technology centered as well because it includes lots of different graphic elements within the same application, some that can be directly manipulated by the user and others that cannot.
