In the begining
In class, we watched Youtube video about the Dyslexia
: allow viewers to have experience about the notion/ topic more effectively though sense of visualization or movement
Elements of media: melting together and describe the notion
– Sound: neutrual music
– Animation: flash
Duel channel: although human brain perceives audio channel and visual channel separately, it can process the notion in the end. ex) bumble bee – we can imagine a picture of bumble bee with music. music or sound becomes metaphor
Limited capacity: each channel has limitation when perceiving information. ex) when watching a film with subtitle together, it is difficult to focus on two visual stuffs due to the limitation of capacity.
Active processing: any information you perceive to convert to make a note/ summarizing = making a note means you understand in your way. In this sense, the Powerpoint is arguable since it takes away students to make a note
Cognitive load: as we have a limited capacity, real overload can occur with same channel or different channel. be careful using music and text channel together.
creating multimedia task, focus on exact contents – intrinsic memory/ Germane load- manipulating or decreasing the intrinsic problem/anything pertinent to illustrate the concept
Depending on the target audiences, the channel should be changed.
deaf audience – visual channel only
Dyslexia – Audio channel will be more effective than using dual channel
focusing on counting, 50% of people miss to see the gorilla
– we miss out a lot so when making a mulitimedia
