Mayer's principles for multimedia learning | instructional design
Germane cognitive load: the mental effort required to process the task's information, make sense of it, and access and/or store it in long-term memory (for example, seeing a math problem, identifying the values and operations involved, and eLearning Companies understanding that your task is to solve the math problem). Intrinsic cognitive load: the mental effort required to perform the task itself (for example, actually solving the math problem). Extraneous cognitive load: the mental effort imposed by the way that the task is delivered, which may or may not be efficient (for example, finding the math problem eLearning Solutions you are supposed to solve on a page that also contains advertisements for books about math). The multimedia instructional design principles identified by Mayer, Sweller, Moreno, and their colleagues are largely focused on minimizing extraneous cognitive load and managing intrinsic and germane loads at levels that are appropriate for the learner.
