Designing instructional videos for asynchronous learning can be challenging. How do you effectively convey the information while keeping learners engaged and motivated? One theory you can use is the Cognitive Theory of Multimedia Learning (CTML). The cognitive psychologist Richard Mayer first articulated CTML in 1997 in an effort to discover the best way to utilize words and pictures to encourage meaningful learning.
Research has found that multimedia learning is most effective when creators avoid cognitive overload by helping learners select, organize and integrate information to reduce extraneous processing this can be achieved by utilizing the twelve principles of multimedia learning.
When designing multimedia content it's important to reduce the amount of effort it takes to understand the information being presented (extraneous cognitive load), manage the amount of effort it takes to understand the specific information you are trying to teach (intrinsic cognitive load), and optimize the amount of effort it takes for the learner to convert the content from working memory to long term memory (germane cognitive load). The following 12 principles can be used to achieve these goals.
Reduce the amount of effort it takes to understand the information:
Manage the effort it takes to understand the specific information:
Optimize the amount of effort it takes for the learner to convert the content from working memory to long-term memory:
