It’s a two-part process

  1. Consumption Period (reading)
  2. Digestion Period (retention)
  • These two stages must always be balanced.
  • Everything you consume must be digested in order for you to retain and use it.
  • What stays in your brain is more important than what goes into your brain.

Types of Information (P.A.C.E.R.)

  1. Procedural - A set of instructions or processes followed to achieve a specific outcome. This is the “how” to do something.
  2. Analogous - Information that is related to something you already have prior knowledge about. Analogy can form without any prior knowledge.
    1. Example he gives: an avid swimmer is learning about muscle contraction and thinks “the muscle contraction cycle reminds me a lot of a swimming technique I use”.
  3. Conceptual - Compared to Procedural information (the “how” to do), this is the “what” to do. Science subjects usually fall under conceptual knowledge.
  4. Evidence - Information that makes conceptual information more concrete. Evidence is often detailed and concrete information
  5. Reference - All the nitty-gritty, specific information that don’t really change your conceptual understanding.

Digestion Strategies

When consuming material for learning, be thinking about these types, is this material:

A set of instructions or processes to be followed to achieve a specific outcome?

TYPE: Procedural

PROCESS: Practice

  • Practice what you read as soon as possible. If you can’t immediately practice what you read:
  • Move on to something else.
  • Stop consuming information, and wait until you have time to practice it.
  • Do not just try to memorize this type of information non-stop without practicing.

Information that is related to something you already have prior knowledge about?

TYPE: Analogous

PROCESS: Critique

  • Once an analogy is established, critique it to determine how good the analogy actually is. Ask:
    • How are these things related?
    • How are they different?
    • In what situation does this analogy not make sense anymore?
    • Is there a better analogy, or can we modify or extend the current analogy?

Facts and explanations, theories and principles, relationships between concepts, applications of concepts?

TYPE: Conceptual

PROCESS: Mapping

  • Conceptual + Procedural = Problem solving and knowledge application
  • Non-linear, network based information.
  • Purpose is to re-create the network of knowledge that the expert has.
  • Mapping forces us to not only think about each fact and concept, but also how they connect to each other to form a bigger picture.
  • As you’re reading, start to map the information so you understand it better. Do this as you are reading.
  • Conceptual information can be used to create analogies.

TYPE: Evidence

PROCESS: Store & Rehearse

  • Evidence type information can be used as examples to prove a conceptual point.
  • Store & Rehearse
  • “Store” means that you just collect that information and note it down somewhere.
  • “Rehearse” means to ask:
    • How to use the information?
    • How to apply the information?
    • What type of conceptual information is this an example of?
  • This type of information should be documented (stored) as soon as it’s identified.
  • Do not waste time overly taking notes for Evidence type information because it will come at the cost of the Procedural, Analogous, and Conceptual processes.

TYPE: Reference

PROCESS: Store & Rehearse

  • Not particularly important.
  • Doesn’t fall under any of the other types of information.
  • Information we might need to know later.
  • Examples:
    • The exact value of a mathematical concept
    • A specific gene involved in a particular mutation
    • The name of a specific molecule of disease
    • A list of attributes used to define a variable for coding.
  • Used for direct fact recall, such as when using flashcards combined with spaced repetition active recall strategy. Go through your flashcards regularly to help solidify this information.
  • Don’t waste too much time for this type of information.

Active Learning

  1. Am I trying to make new information simpler to understand?
  2. Am I grouping the information together?
  3. Am I thinking about how what I’m learning relates to the big picture?
  4. Am I recalling things I’ve learned from memory? If the answer to any of these questions is no, try to make it a yes.
