In the age of information overload, the art of learning can feel like spinning plates on a tightrope. Enter Dr. Justin Sung's method of 'thinking on paper'—a tool designed to cut through the cognitive clutter and streamline the learning process. This technique is not just about scribbling notes but involves a strategic engagement with information that transforms chaos into clarity.
The Essence of 'Thinking on Paper'
At its core, 'thinking on paper' is a method for managing the mental juggle that comes with absorbing new information. Dr. Sung, a veteran of learning science and a former medical doctor, argues that this technique can halve the time spent on learning tasks. By externalizing thoughts onto paper, learners can organize and process information more effectively, reducing the sense of being overwhelmed.
The conventional approach often leads to two common pitfalls: first, the more information you consume, the more confusion mounts; second, the instinctive urge to write everything down can bypass essential cognitive processes. As Sung puts it, "It's the learning equivalent of going for a run to get fit, then jumping in a car halfway through."
Make It Wrong, Make It Shorter, Make It Again
The technique revolves around three guiding principles:
-
Make It Wrong: Contrary to traditional note-taking, the goal here is not to capture perfect, polished notes. Instead, it's about jotting down ideas—even incorrect ones—to visually map thoughts and provoke cognitive engagement. "If what you write is right, you're doing it wrong," Sung insists. This approach primes the brain for deeper understanding as you work through the chaos of initial impressions.
-
Make It Shorter: Writing in keywords rather than full sentences encourages active processing. Sung explains, "Research shows retention and understanding go down as word count goes up." By distilling thoughts into concise keywords, learners focus more on finding connections than on crafting perfect prose.
-
Make It Again: This step emphasizes the iterative nature of learning. As you revisit and reorganize your notes, you're not just tidying up; you're reinforcing memory and understanding through active re-engagement. Sung notes, "The act of reorganizing all the ideas is what strengthens the memory."
Applying the Technique
This method isn't limited to academic study but is equally applicable to professional environments. Whether navigating a complex meeting or strategizing a project, 'thinking on paper' can help distill and clarify ideas. The iterative process of revisiting and refining notes mirrors the real-world necessity to adapt and update our understanding as new information emerges.
While 'thinking on paper' offers a potent tool for enhancing learning, it's part of a broader toolkit. As Sung suggests, integrating this technique with other learning strategies can further enhance efficiency and productivity.
In a world where information is abundant but clarity is scarce, learning to think on paper might just be the secret weapon for mastering new skills. So, the next time you're faced with a daunting pile of information, ask yourself: Are you ready to make it wrong, shorter, and again?
