Limitations of Working Memory And Instruction As you remember from Chapter 3, the working memory is a limited
capacity processor that can be overloaded by two much information at one time or
the requirement to execute too many complicated mental processes at once.
Cognitive load theory provides a framework for understanding how the limited
capacity of working memory can influence instruction. According to cognitive
load theory, instruction poses three different types of cognitive load on working
memory (Bannert, 2002; Sweller, 1999).
• Intrinsic cognitive load derives from the material to be learned, and
is determined by the complexity of the material to be learned and
learners’ prior knowledge about that material. Intrinsic load is high for
complex and unfamiliar material. 32 • Extrinsic cognitive load results from inadequately designed
instruction. Typically this occurs when extra...
