The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, excessive cognitive load can hinder learning, as learners may struggle to process new information when their mental resources are overwhelmed. However, research suggests that instructional design can mitigate this by segmenting complex tasks into smaller steps, thereby reducing unnecessary mental strain. This approach, known as 'chunking,' allows learners to focus on one piece of information at a time, facilitating deeper comprehension and retention. Moreover, studies indicate that the effectiveness of chunking varies across different types of content, such as visual versus textual material, and is influenced by the learner's prior knowledge and expertise in the subject area.
