"A theory which explains how learning happens when learning with text and images. The Theory of Multimedia Learning states: (1) Learning happens in working memory, which has a very small capacity. Overloading working memory demotivates a learner. (2) Working memory has two channels, one for images, and the other for words (spoken and written). The load experienced in each channel is separate, so e.g. if no images are used, that available space is simply wasted, it can’t be reassigned to cope with an overload in text (3) There kinds of processing can occur in working memory: being distracted, selecting what is important, connecting new pieces of knowledge with one another and with prior knowledge."
