What is the forgetting curve and how does it affect learning?

The forgetting curve is a concept in learning science that illustrates how information is lost over time when there is no attempt to retain it. It suggests that memory strength declines rapidly after initial learning. By understanding this curve, you can intervene at the right moments to reinforce knowledge, such as Richard Mayer’s multimedia learning principles, ensuring that the information transitions from short-term memory into stable, long-term memory retention.

What is the optimal spaced repetition schedule for reviewing new information?

An optimal spaced repetition schedule involves reviewing material at increasing intervals to combat the forgetting curve. For complex topics like multimedia learning, a common schedule includes a first review within 24 hours, followed by reviews at three days, one week, and one month. These optimal review intervals are designed to challenge the brain just as it is about to forget, which significantly strengthens neural pathways and improves your ability to recall information permanently.

Which form of review is most beneficial for long-term retention?

The most beneficial form of review is active recall, which involves testing yourself rather than passively re-reading notes. When applying this to Richard Mayer’s principles, you should try to explain the concepts from memory or apply them to a design problem. Combining active recall with a spaced repetition schedule forces the brain to retrieve information, which is a much more effective strategy for securing long-term memory retention than passive study methods.

Input question

I want to learn about the forgetting curve and What is the optimal schedule to review new information that I learn with regard to the forgetting curve to optimize retention? For example, right now I'm learning the principles of multimedia learning from Richard Mayer in the book and I'm learning useful principles. I want to know how often I should review these principles to get them into my long-term memory permanently? Is there a form of review which is most beneficial?
