Chunking is a cognitive strategy that involves breaking down large pieces of information into smaller, manageable units or "chunks." This technique helps improve memory retention and recall by organizing data into familiar patterns. For example, when trying to remember a long string of numbers, people often group them into sets, like phone numbers, making it easier to remember. This method is widely used in various fields, including education and psychology. By applying chunking, learners can enhance their understanding of complex subjects, such as mathematics or language acquisition, by focusing on smaller, interconnected concepts rather than overwhelming amounts of information at once.
