Short-term memory is a component of the memory system that holds information for about 20 seconds. It is not stored in long-term memory and can't be retrieved at a later date as it is not processed. When I'm introduced to new people, their names normally don't stay in memory but for 1 to 2 seconds as I am not very good with names. For me to move their names to long-term memory, I have to process the information so that I can remember.

It is your mental "workbench" of the memory system. It is the interface where new information is held temporarily (short-term) and combined with knowledge from long-term memory to solve problems, comprehend a lecture, etc. Please watch the following video via the link below and then provide your reflective comments as to why all of these are important for teaching and learning. https://www.youtube.com/watch?v=UWKvpFZJwcE
