Learning Strategies
Interleaving
Mix related topics to improve adaptability.
Definition
A learning approach where related topics or problem types are mixed during practice to improve the ability to distinguish between them and apply the right method.
💡 Core Idea
Instead of practicing one type of problem repeatedly (blocking), interleaving forces learners to identify the type of problem before solving it, strengthening adaptability and long-term retention.
🔍 How It Works
- Alternating topics requires recognizing problem type before choosing a solution.
- The added difficulty increases cognitive effort, which deepens learning.
- Improves transfer by training learners to discriminate between similar concepts.
🎯 How to Apply
- Mix math problems from different chapters in one set.
- Alternate between different skill drills in sports training.
- Use varied question formats in assessments.
- Combine related topics in review sessions.
📌 Quick Example
A language learner studies vocabulary, grammar, and pronunciation in rotation instead of focusing on just one skill per session.
⚠️ Common Mistakes
- Mixing topics that are too different, causing confusion.
- Introducing interleaving too early before foundational skills are learned.
- Misinterpreting slower short-term performance as lack of learning.
Key Takeaway
Mix related skills or topics to train recognition and adaptability, even if it feels harder at first.
