Dr. Greg Ashman explores cognitive load theory, working memory vs long-term memory, and the importance of evidence-based teaching. He emphasizes the need for structured teaching methods and debunking the idea that kids only need to practice skills. Ashman advocates for questioning teaching methods and ensuring they are based on evidence for optimal student learning outcomes.
Acquiring substantial knowledge is crucial for developing critical thinking skills, not just practicing skills.
Cognitive load theory emphasizes the significance of intrinsic and extraneous load in learning for effective teaching strategies.
Balancing productive struggle with explicit instruction optimizes student learning outcomes according to cognitive load theory.
Deep dives
The Importance of Knowledge in Teaching and Learning
Knowledge plays a crucial role in developing critical thinking skills. The idea that students solely need to practice skills without acquiring substantial knowledge is deemed damaging. Cognitive load theory highlights the significance of intrinsic and extraneous load in learning, emphasizing the need for a solid knowledge base to enhance student learning.
Dr. Greg Ashman's Background and Expertise
Dr. Greg Ashman, a teacher with a background in natural sciences and teaching qualifications, delves into cognitive load theory. As the author of a book on cognitive load theory, Ashman explores concepts such as working memory, long-term memory, and the impact on effective teaching strategies. His experience in education and research provides valuable insights for educators.
Teaching Strategies Based on Cognitive Load Theory
Effective teaching strategies align with cognitive load theory principles, emphasizing explicit instruction followed by student engagement. Ashman discusses the importance of clear learning objectives, breaking down complex concepts, and gradual release of control to support optimal learning. Strategies like daily and monthly review aid in reinforcing learning and optimizing cognitive load.
Balancing Struggle and Explicit Instruction
Productive failure and productive struggle are concepts that aim to engage students in problem-solving activities to enhance learning. While deliberate difficulties can stimulate learning, cognitive load theory suggests that explicit instruction prior to problem-solving activities often yields better results. Striking a balance between struggle and explicit teaching can optimize student learning outcomes.
Evidence-Based Teaching Methods and Continuous Learning
Dr. Ashman emphasizes the importance of evidence-based teaching methods over philosophically driven approaches. Encouraging educators to question teaching practices and seek empirical evidence ensures optimal learning outcomes for students. Continuous learning and critical evaluation of teaching methods based on evidence are key for effective educational practices.
Greg Ashman—author of multiple books including A Little Guide for Teachers: Cognitive Load Theory, deputy principal, and professor—sits down with Susan Lambert on this episode to discuss cognitive load theory and how it applies to how students learn and how to best teach them. Together their conversation covers cognitive load theory, including an exploration of working memory and long-term memory; intrinsic load and extraneous load; biologically primary vs. biologically secondary knowledge; and how to apply these concepts in the classroom. Ashman also provides listeners with helpful advice on ensuring their teaching practices are based on evidence.
Quotes: “I now know I shouldn't have felt guilty, but I also know that I could have taught that from the outset in a much more structured way where the students would have left understanding the concepts better without wasting time.” —Greg Ashman
“This idea that kids don't need to know anything anymore, they just need to practice skills is really quite a pernicious and damaging idea.” —Greg Ashman
“Think about the teaching methods that you're being presented with. Ask about the evidence and question whether this is really the optimal way of teaching literacy or whatever it is, or whether it's more based on wishful thinking.” —Greg Ashman
