Most adults find themselves learning in a way that mirrors their school days — reading, highlighting, and hoping the information will stick. However, extensive research in learning science reveals that this traditional approach is ineffective for retaining information. In fact, it can be counterproductive. By embracing three key principles — spaced repetition, retrieval practice, and interleaving — self-taught professionals can enhance their learning efficiency and retention, investing less time and effort than they might think.
What learning science actually tells us
Learning science, rooted in cognitive psychology, has uncovered how memory and skill acquisition truly work. Over the past 50 years, thousands of studies have demonstrated that the techniques that feel most productive often yield the lowest retention rates. Conversely, methods that may feel uncomfortable or challenging tend to be the most effective.
A 2013 review by Dunlosky and colleagues evaluated numerous learning techniques and identified two strategies that stood out: practice testing (retrieval) and distributed practice (spacing). These strategies consistently outperform traditional techniques like highlighting, rereading, and summarization, which were rated as low utility. Unfortunately, many adults still rely on these less effective methods.
Consider the following example: A senior product manager dedicated 30 hours over three weekends to an SQL course, engaging with the material through videos and exercises. Three months later, he found himself struggling to recall basic syntax. When he shifted his approach, dedicating just 15 minutes each workday to querying real data and looking up syntax as needed, he improved significantly. In six weeks, he was writing SQL queries fluently. His new method required less time and yielded better results, demonstrating the power of applying learning science principles.
The mistake — learning the way school taught you
Many self-taught professionals unknowingly perpetuate outdated learning habits that hinder retention. Techniques such as highlighting and rereading may feel active and productive, but research indicates they offer minimal long-term benefits. Highlighting may engage learners in the moment, but it rarely leads to deeper understanding or memory retention. Similarly, rereading creates a false sense of familiarity, tricking learners into believing they grasp the material. The discomfort of trying to recall information is where genuine learning occurs.
Cramming, while seemingly efficient, has also been shown to be ineffective. Research indicates that concentrated bursts of information lead to faster decay of knowledge compared to spaced sessions. Additionally, the notion of learning styles has been debunked; matching teaching methods to individual preferences does not enhance outcomes. Instead, the effective techniques of retrieval, spacing, and interleaving work for everyone.
The three principles that actually work
Understanding the three pillars of evidence-based learning is crucial for anyone looking to improve their retention and understanding.
Spaced repetition involves reviewing information at increasing intervals, which significantly enhances long-term retention. The Ebbinghaus forgetting curve illustrates that forgetting is a natural part of the learning process, and the struggle to recall information is what solidifies memory. Tools like Anki and SuperMemo can automate spaced repetition for learners.
Retrieval practice is the act of actively recalling information, and it stands as the most effective learning strategy. Closing your notes and testing yourself produces greater retention than rereading the same material multiple times. This "testing effect" has been validated through extensive research, emphasizing the importance of engaging with material beyond passive reading.
Interleaving refers to mixing different topics or types of problems within a single study session. While this might initially decrease performance during practice, it fosters better long-term retention and transfer of knowledge. By switching contexts, learners develop a deeper understanding and are better equipped to discriminate between concepts.
When these three principles are applied together, they create a powerful trifecta for effective learning. Spacing provides optimal timing for retrieval, while retrieval reinforces memory, and interleaving enhances cognitive flexibility.
How to apply this as a working professional
As a working professional, time is often limited. Fortunately, the principles of learning science can be seamlessly integrated into your routine, even with fragmented schedules.
Utilize micro-sessions. Instead of dedicating hours to study marathons, focus on ten-minute sessions throughout your day. This approach naturally incorporates spaced repetition and allows you to leverage brief moments between meetings or during breaks.
Practice retrieval immediately after exposure. After engaging with new material, take a moment to close your notes and jot down what you remember. This could be a few sentences or bullet points. The effort of recalling information is where real learning happens.
Mix topics. Rather than focusing solely on one subject, interleave different topics or skills during your learning sessions. For example, if you’re studying negotiation, sales, and strategic thinking, rotate between them. This enhances retention and helps you see connections among concepts.
Test yourself frequently. Transform every interaction with material into a mini-test. Predict upcoming content while reading, or summarize key points after watching a video. These constant micro-tests contribute significantly to retention.
Apply knowledge quickly. Whenever possible, implement what you’ve learned in real scenarios. Applying knowledge reinforces retention far more effectively than passive reading, as on-the-job learning is naturally integrated into the process.
By adopting a micro-learning approach, you can reinforce your understanding of concepts through daily lessons that align with your work. The cumulative effect over time can lead to substantial improvements in retention and recall.
Making this a daily practice
Establishing a habit is more crucial than having a complex system. Start with one skill or concept you want to learn, and commit to spending ten minutes a day on it for 30 days.
In each session, spend five minutes recalling what you learned the previous day (retrieval) and five minutes on new material. At the end of the session, close your notes and write down three things you remember. The next day, try to recall these before checking your notes.
After a couple of weeks, introduce interleaving by adding a second topic to your routine. This will help increase cognitive friction and enhance learning.
You'll know you’re on the right track when the process feels challenging. Real learning often involves discomfort, as the struggle is part of building lasting memories. The pleasant feeling of passive reading typically indicates ineffective learning.
This approach aligns perfectly with Omie's daily lesson model. With just one lesson a day, retrieved the following day and interleaved with future learning, you can easily incorporate these principles into your routine.
What good learning practice looks like
Effective learning leads to long-lasting knowledge. When you can recall what you learned months ago without having to reread it, you know you’ve mastered the material. Concepts learned in one context should transfer to others, allowing you to apply negotiation principles in team discussions or strategic frameworks in hiring decisions.
You’ll notice a shift — learning becomes a smoother process. Knowledge from short sessions sticks better than information acquired through lengthy cramming. You’ll develop a clear distinction between what feels familiar and what you truly know, making the act of recalling a reliable indicator of genuine understanding.
Ultimately, you’ll become a faster learner, mastering new domains more efficiently as your grasp of effective learning techniques improves.
The one-sentence version
Space, retrieve, interleave. Highlighting feels productive but doesn't work.
