Interleaving is a learning technique that involves mixing different topics or subjects during study sessions. Instead of focusing on one subject for a long period, learners alternate between various topics. This approach helps improve retention and understanding by encouraging the brain to make connections between different concepts. Research shows that interleaving can enhance problem-solving skills and adaptability. For example, when studying math problems, switching between different types of equations can lead to better performance than practicing one type at a time. This method is often contrasted with blocked practice, where similar tasks are grouped together.
