| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online.Cognitive load is
a term that refers to the load on working memory during instruction.
Instruction may be aimed at teaching learners problem solving skills,
thinking and reasoning skills (including perception, memory, language,
etc.). Many would agree that people learn better when they can build on
what they already understand (known as a schema), but the more a person
has to learn in a shorter amount of time, the more difficult it is to
process that information in working memory. Consider the difference
between having to study a subject in one's native language versus trying
to study a subject in a foreign language. The cognitive load is much
higher in the second instance because the brain must work to translate
the language while simultaneously trying to understand the new
information. Another aspect of cognitive load theory involves
understanding how many discrete units of information can be retained in
short term memory before information loss occurs. An example of this
principle that seems to be commonly cited is the use of 7-digit phone
numbers, based on the theory that most people can only retain seven
"chunks" of information in their short term memory. |
