Summary of John Sweller - ACE Conference/researchED Melbourne

Summary of Main Ideas, Concepts, and Lessons

• Human Cognitive Architecture:

  The speaker, John Sweller, challenges the notion that students learn more easily outside of the classroom than in it. He argues that this belief is rooted in a misunderstanding of human cognitive architecture.

  • Biologically Primary Information: Skills and knowledge humans have evolved to acquire easily and automatically (e.g., language acquisition, problem-solving, social skills).
  • Biologically Secondary Information: Skills and knowledge that are taught in schools and require Explicit Instruction (e.g., reading, writing, mathematics).
• Importance of Explicit Instruction:

  Unlike biologically primary skills, biologically secondary skills do not come naturally and must be taught explicitly. This is critical for skills that are domain-specific and not easily acquired through general cognitive abilities.

• Cognitive Load Theory:

  Sweller introduces principles of Cognitive Load Theory, emphasizing the importance of long-term memory in learning. Key points include:

  • Information Store Principle: A vast store of information (long-term memory) is essential for cognitive processing.
  • Borrowing and Reorganizing Principle: Knowledge is often acquired by imitating others and reorganizing that information.
  • Working Memory Limitations: Working memory can only handle a limited amount of novel information at a time, which is crucial for understanding new concepts.
• Instructional Recommendations:

  Sweller discusses various cognitive load effects that can enhance learning:

  • Worked Example Effect: Demonstrating problem-solving methods leads to better learning than having students solve problems independently.
  • Split Attention Effect: Integrating text and diagrams can improve understanding, but redundancy (providing unnecessary information) can hinder learning.
  • Redundancy Effect: Avoid providing the same information in multiple forms if it does not add value, as this can overload working memory and impede learning.
• Transformative Nature of Education:

  Education is transformative because it builds a substantial knowledge base in long-term memory, enabling individuals to perform tasks they could not do without that knowledge.

Methodology and Recommendations

• Explicit Instruction: Focus on teaching domain-specific skills explicitly.
• Utilize Worked Examples: Present worked examples before asking students to solve problems independently.
• Integrate Information: Physically integrate related information (like diagrams and text) to reduce cognitive load.
• Avoid Redundancy: Do not present unnecessary information that does not add value to the learning process.
• Encourage Knowledge Building: Foster environments that allow students to build long-term memory through structured learning experiences.

Notable Quotes

— 00:40 — « Look how difficult it is for some kids to learn in class; look how easy it is for them to learn information which can be far more complex outside of class. »

— 01:40 — « It's entirely erroneous. »

— 06:16 — « You can't teach somebody something they already know how to do. »

— 11:41 — « They're right to place emphasis on them but that doesn't mean that kids ought to be taught how to learn them; a waste of time. »

— 30:04 — « It's transformative. »
