Rachel Tustin on 12 Dec 09This particular multimedia example is a video about the greenhouse effect, and its title is an engaging aspect that attracts learner by referencing a commonly known children's story. Mayer described the technology centered approach as being based in how and what technologies can be incorporated into the learning process (Mayer, 2009, pp. 10-11). It is definitely technology centered first and foremost. Throughout the video, it uses a great deal of overlaying video with static images or content so that the eye is engaged and drawn into the movement happening on screen. In this case, it meets with Mayer's assumption of dual coding in its design, in that it operates both on an auditory and visual channel (p. 64). In this case, in order for the learner to construct knowledge the auditory channel is the most important because the video images themselves really just augment the commentary, rather than presenting identical content visually. The images are stunning; there are amazing 3-D representations of earth, and video of the first atomic explosion. While these images are captivating, they don't serve as a second representation of the content itself. The learning that takes would not be considered active learning by Mayer's criteria, because there it is not structured in such a way that the learner does not have any repetitive elements to select and focus on in order to sequence the content in order to build knowledge (p. 71). Also, there is not an opportunity for the learner to integrate the visual and audio components to build knowledge, because the content is primarily in the audio while the video images are more oriented toward holding the learner's attention instead of presenting content or concept related information (p. 71).
