In his book "Grasp," Sanjay Sarma explores the latest scientific insights into how we learn and how our education systems can be improved to better align with our cognitive processes. As the vice president for open learning at MIT, Sarma brings a wealth of experience and expertise to this critical examination of traditional schooling methods and the potential for transformative change in education.
Introduction
Our current education system, with its emphasis on rote memorization, standardized testing, and passive learning, is increasingly at odds with what we now know about how the human brain learns best. "Grasp" delves into the cognitive science behind learning and memory, offering a compelling case for reimagining our approach to education.
The book challenges long-held assumptions about learning and intelligence, arguing that many common practices in schools today are not only ineffective but can actually hinder students' ability to acquire and retain knowledge. By exploring cutting-edge research and innovative educational models, Sarma presents a vision for a more engaging, effective, and equitable approach to learning.
The Mismatch Between Schools and Brains
One of the central themes of "Grasp" is the disconnect between how our brains naturally learn and how traditional education systems are structured. Sarma argues that many aspects of conventional schooling work against our cognitive processes, leading to suboptimal learning outcomes.
The Problem with "Winnowing"
A key issue Sarma identifies is the prevalence of what he calls "winnowing" in education. This refers to the practice of using various metrics and assessments to separate "worthy" students from "unworthy" ones. Common examples include:
- IQ scores
- Standardized tests
- High-pressure exams
While these methods are often justified as ways to identify innate ability, Sarma argues that they fail to capture intelligence fully and can unfairly disadvantage many promising students. This approach not only fails to accurately measure potential but also encourages inefficient learning strategies and potentially discourages many talented individuals from pursuing further education.
The Cost of Outdated Systems
The consequences of these misaligned educational practices are significant. Sarma suggests that countless potential "Einsteins" may have been lost to history due to factors like geography, gender, class, or other variables that traditional education systems fail to account for. In an era where we face complex global challenges like climate change, we can ill afford to waste human potential in this way.
Rethinking Learning: It Doesn't Have to Be Unpleasant
One of the most powerful insights in "Grasp" is the idea that learning doesn't have to be an unpleasant or difficult experience. In fact, Sarma argues that it works better when it's not.
Learning as Our Natural State
To illustrate this point, Sarma asks readers to consider the way young children learn through play and exploration. A child at the beach, for example, naturally engages in scientific inquiry as they discover the properties of water, sand, and sunlight. This innate curiosity and drive to understand the world around us is fundamental to human survival and development.
The Origins of "No Pain, No Gain" in Education
So why does formal education often feel so far removed from this natural, joyful process of discovery? Sarma traces this back to outdated assumptions about learning, including the idea that it should be like weight-lifting – difficult and sometimes painful. He also points to the influence of early 20th-century ideas that favored easily measurable and standardizable teaching methods, which were useful for building large-scale education systems but often at the cost of engagement and deeper understanding.
Engaging Education: Beyond Memorization
Sarma argues that successful education should go beyond mere memorization of facts. Instead, it should teach students how to think using the principles of various disciplines – to see the world and engage with it in new ways. This requires providing context and opportunities for practical application, not just raw information.
He offers the example of "Course 2.007" at MIT, where engineering students not only learn theory but are constantly challenged to apply it through hands-on projects. The course culminates in a robot-building competition rather than a traditional exam, combining the benefits of assessment with engaging, practical application.
The Power of Spaced Learning
One of the key cognitive science insights that Sarma highlights is the importance of spaced learning. This concept stands in stark contrast to the common practice of cramming before exams.
The Problem with Cramming
While cramming can be effective for short-term recall in test situations, it's terrible for long-term retention and understanding. This disconnect between how we often study and how our brains actually learn best is another example of the misalignment between traditional education practices and cognitive science.
Long-Term Potentiation and Spaced Learning
The science behind spaced learning relates to a process called long-term potentiation, where synapses in the brain are strengthened over time. When learning is spaced out, these synaptic connections are reinforced more intensely, leading to better retention and understanding.
Practical Applications of Spaced Learning
Sarma suggests several ways to incorporate spaced learning into education:
- Pre-tests before actual tests, compelling students to recall information multiple times.
- Interleaving, which involves alternating between different subjects in study schedules.
- Allowing for some forgetting between study sessions, as the act of recalling partially forgotten information strengthens memory connections.
These techniques have been shown to significantly improve retention and understanding compared to traditional cramming methods.
Harnessing Curiosity for Enhanced Learning
Another powerful insight from cognitive science that Sarma explores is the role of curiosity in learning. He argues that curiosity can supercharge the learning process and should be a central consideration in educational design.
The Neuroscience of Curiosity
Recent neuroscience research has shown that curiosity can significantly enhance long-term potentiation, the process by which memories are formed and strengthened. When we're curious about something, our brains are primed to learn and retain information more effectively.
Curiosity-Driven Education Models
Sarma discusses several educational approaches that have attempted to harness the power of curiosity:
- John Dewey's efforts to build learning environments around students' natural interests.
- Montessori schools, which merge play and learning for young children.
- Discovery education approaches, which emphasize internal motivation and imagination in the learning process.
These models are based on the idea that knowledge is something people actively create, rather than passively receive – a concept championed by influential psychologist Jean Piaget.
Benefits and Limitations of Discovery Learning
While there's evidence that curiosity-driven approaches like Montessori education can be highly effective, Sarma acknowledges that they also face challenges. These include:
- Difficulty in scaling up and replicating due to resource requirements and the need for skilled teachers.
- The need for some level of instruction to give shape and context to discovery-based learning.
The Necessity of Structure and Formal Instruction
While emphasizing the importance of curiosity and discovery in learning, Sarma also argues for the continued relevance of structured instruction. He suggests that the most effective educational approaches will combine elements of both discovery-based and traditional instructional methods.
Balancing Discovery and Instruction
Sarma uses the analogy of a child learning about sand at the beach versus in a classroom to illustrate this point. While the beach experience provides valuable firsthand knowledge, the classroom instruction offers necessary context and scientific explanation. Together, these experiences create a more complete understanding.
Structured Learning at Scale
One of the challenges in education reform is finding ways to implement more flexible, engaging teaching styles while still maintaining the ability to educate large numbers of students. Sarma highlights several promising approaches:
- "42," a coding school that uses mastery learning and peer instruction.
- MIT's technology-enabled active learning (TEAL) system, which combines lectures, simulations, experiments, and group work.
These models demonstrate that it's possible to incorporate cognitive science insights into structured learning environments that can be scaled up effectively.
The Potential for Educational Transformation
In the final sections of "Grasp," Sarma makes a compelling case for the urgent need to reimagine our approach to education. He argues that the current moment, with its rapid technological advancements and societal upheavals, presents a unique opportunity to overhaul outdated educational practices.
Technology's Role in Education Reform
While acknowledging that technology is not a panacea for educational challenges, Sarma sees great potential in its ability to support more effective learning methods. He cautions, however, against using technology merely as a cost-cutting measure or a means of increased surveillance of students.
Challenges and Considerations
Sarma identifies several key challenges in implementing widespread educational reform:
- The need to improve access to quality education for all students.
- Moving away from emphasis on innate differences and "winnowing" practices.
- Developing methods that provide both factual knowledge and the skills to apply it practically.
A Call to Action
Ultimately, "Grasp" serves as a call to action for educators, policymakers, and anyone interested in the future of learning. Sarma argues that by applying the insights of cognitive science and leveraging new technologies, we can create educational systems that are more engaging, effective, and equitable.
