Understanding How Learning Really Works
“Make It Stick: The Science of Successful Learning” by Peter C. Brown, Henry L. Roediger III, and Mark A. McDaniel challenges common misconceptions about effective learning. It reveals that many popular learning techniques are surprisingly ineffective, while seemingly counterintuitive methods prove remarkably powerful. The book emphasizes the importance of understanding how memory works and leveraging that understanding to optimize the learning process. It’s not just about cramming information; it’s about transforming that information into durable, usable knowledge.
The Illusion of Fluency
Many believe that if something feels easy to learn, it’s been effectively learned. This is the illusion of fluency. Repeated exposure or effortless comprehension doesn’t guarantee retention. The book argues that the struggle itself, the deliberate effort to retrieve information and overcome obstacles, is essential for encoding knowledge into long-term memory. The feeling of ease often misleads learners into underestimating their learning needs.
Retrieval Practice: The Power of Testing
One of the most significant takeaways from the book is the power of retrieval practice. This involves actively recalling information from memory, rather than passively rereading or reviewing material. Testing yourself, even without looking at the answers, is far more effective than simply rereading notes.
Retrieval practice strengthens memory traces, making information more accessible and resistant to forgetting. The act of struggling to retrieve strengthens memory far more than passively reviewing.
Interleaving: Mixing it Up
Interleaving is another key strategy highlighted in the book. Instead of focusing on one topic at a time, interleaving involves mixing up different subjects or types of problems. For instance, studying math, history, and science in alternating sessions rather than dedicating a block of time to each subject separately.

While initially more challenging, interleaving forces the brain to discriminate between different concepts, leading to stronger and more flexible learning. It also helps identify knowledge gaps more readily.
Elaboration: Connecting New Information
Elaboration involves actively connecting new information to existing knowledge. This might involve relating new concepts to personal experiences, creating analogies, explaining the material to someone else, or generating questions and answers. Simply understanding the material is not enough; it needs to be integrated into one’s existing mental framework.
Dual Coding: Engaging Multiple Senses
The book promotes dual coding, which is the integration of verbal and visual information. Using diagrams, images, and other visual aids alongside text can improve learning and memory. The brain processes visual and verbal information differently, and combining them creates a richer and more memorable representation of the material.
Spacing Effect: Timed Repetition
The spacing effect demonstrates the importance of spaced repetition. Instead of cramming all information at once, spreading out learning sessions over time leads to superior retention. Repeated retrieval of information at increasing intervals strengthens memory. This principle is fundamental to effective long-term learning.

Metacognition: Knowing How You Learn
Metacognition refers to awareness and understanding of one’s own thought processes. The book stresses the importance of reflecting on one’s learning strategies and identifying what works best. Effective learners actively monitor their understanding, identify knowledge gaps, and adjust their learning strategies accordingly.
Feedback: Identifying and Correcting Errors
Feedback is essential for identifying misconceptions and correcting errors. Receiving timely and specific feedback allows learners to adjust their understanding and improve their performance. It’s important to actively seek feedback and use it to refine learning strategies.
Concrete Examples and Analogies: Bridging the Gap
The authors note the value of using concrete examples and analogies to make abstract concepts more accessible. Relating new information to familiar examples can aid comprehension and retention, especially for complex or abstract topics.
The Importance of Sleep and Rest
The book also highlights the critical role of sleep and rest in the consolidation of memories. Sleep allows the brain to process and consolidate newly acquired information, transferring it from short-term to long-term memory. Insufficient sleep impairs learning and memory.
Mindset and Motivation: The Role of Beliefs
The book subtly addresses the importance of mindset and motivation. Believing in one’s ability to learn (growth mindset) and having a genuine interest in the subject matter are key factors in successful learning. Intrinsic motivation, driven by curiosity and interest, is more powerful and sustainable than extrinsic motivation, driven by rewards or grades.
Practical Application to Daily Life: Actionable Insights
The principles outlined in “Make It Stick” are applicable to various aspects of life. Whether it’s learning a new skill, mastering a subject, or improving professional performance, the strategies discussed can dramatically improve learning efficiency and retention.
Studying: Use retrieval practice (self-testing), interleaving (mixing subjects), and spaced repetition. Elaborate on the material, connect it to existing knowledge, and use dual coding.
Professional Development: Apply retrieval practice to review project details, interleave different tasks to improve focus, and use feedback from colleagues to identify areas for improvement.
Personal Growth: When learning a new language or skill, use spaced repetition, interleave practice sessions with other activities, and find ways to elaborate on what you’re learning by relating it to your experiences.
Parenting: Encourage children to use retrieval practice, avoid simply giving them answers, and create a learning environment that values effort and struggle.
Embracing the Challenge
“Make It Stick” offers a powerful message: effective learning is not always easy or comfortable. It requires effort, deliberate practice, and a willingness to the struggle. By understanding how memory works and applying the principles outlined in the book, individuals can improve their ability to learn, retain information, and apply knowledge effectively, leading to greater success and fulfillment in various aspects of their lives. The key is to shift from a passive to an active approach to learning, challenges and strategies that may feel difficult initially but ultimately yield far greater and more durable results.
