Latest / New Teacher Talk / Ep 151: Beyond Repetition: Four Brain-Based Strategies That Actually Work
Transcript
- Welcome to New Teacher Talk.
- My name is Ken King,
- and I am an education professor at Aurora University in
- Aurora, Illinois.
- Does repetition really help us master new information?
- It's a question I raise often when teaching a course on
- learning theories.
- I like to begin that course with a simple classroom
- activity, one that gets people thinking.
- I give students a series of true or false statements and
- ask them to show agreement or disagreement by moving across
- the room toward a sign that reads either true or false.
- One statement always catches people off guard.
- Repetition alone will produce mastery of new information.
- And more often than not,
- the majority of students get it wrong.
- It's a bit of surprise, sometimes even unsettling,
- because this repetition is a strategy many of us have used
- and relied on for years.
- Today,
- I'm going to share why repetition alone is not enough and
- more importantly,
- offer you four powerful strategies that actually work.
- These approaches are backed by brain science that can help
- you or your students learn more effectively and retain
- information longer.
- Let's start by considering why repetition alone is not
- enough.
- When students simply repeat information, for example,
- rereading notes or drilling facts,
- they're often relying on short-term rehearsal rather than
- meaningful encoding.
- The brain's working memory has limited capacity and
- duration, just a few odd aims or just a few seconds.
- Consider the number of locker combinations,
- the times you repeated how to spell a word before writing
- it down,
- or a list of things you planned to buy but forgot to.
- All of these examples were learned briefly and then
- immediately forgotten,
- sometimes before you were able to use the information you
- needed.
- This illustrates the ethereal nature of working memory.
- For information to be retained and usable later, it
- must be actively processed and meaningfully connected with
- existing knowledge.
- The stage is not passive, requires a learner to analyze,
- organize,
- and relate the new information to what they already
- understand.
- When we organize new information,
- such as by categorizing it, creating mental images,
- making comparisons or generating examples,
- we enhance the likelihood that we'll be transferred from
- working memory into long-term memory.
- The sophistication of a learner's existing knowledge plays
- a crucial role here.
- The more developed and interconnected a student's prior
- understanding, the easier it is to interpret new ideas,
- to detect patterns,
- and to anchor unfamiliar content to familiar mental
- structures.
- In other words,
- new information doesn't enter an empty mind if it fits into
- a growing framework.
- This is why building background knowledge and activating
- prior learning are so important in instruction.
- Some effective strategies in support integration include
- making analogies or comparisons.
- For instance,
- comparing the circulatory system to a road network,
- asking how and why questions to deepen analysis,
- creating concept maps to visualize relationships among
- ideas,
- rephrasing information in one's own words to support elaboration,
- using storytelling or narratives to make abstract content
- more memorable,
- and teaching others or explaining concepts aloud,
- which forces deeper processing.
- By engaging in these types of elaborative thinking,
- learners move beyond surface level exposure and begin to
- build lasting, retrievable mental representations,
- strengthening their capacity to use knowledge flexibly in
- the future.
- Furthermore,
- rote repetition often leads to what's known as the fluency
- illusion,
- a cognitive trap where students mistake in familiarity for
- true understanding.
- When learners repeatedly read or rehearse the same material
- without engaging in deeper processing,
- the content begins to feel easier, more recognizable.
- This sense of ease gives the illusion that they have
- mastered the material, when in reality,
- they may not be able to apply it into a new context,
- explain it properly,
- or retrieve it without cues or prompts.
- For example,
- a student might read their notes on the water cycle several
- times and feel confident that they know it,
- simply because the words look and sound familiar.
- However,
- if asked to describe the process in their own words or
- explain why condensation happens, they may struggle,
- revealing that true understanding has not taken place.
- This illusion is especially dangerous because it can lead
- to overconfidence, under preparation,
- and gaps in performance during assessments or real-world
- problem solving.
- Students may believe that they do not have to practice when
- in fact,
- they haven't developed flexible or usable knowledge.
- So the key takeaway,
- learning that sticks involves effortful,
- meaningful processing, not just repetition.
- Rote practice and memorization does not lead to rich and
- meaningful understanding,
- and may mislead you in recognizing how much you really do
- understand.
- Let's consider now some strategies that support long-term
- learning.
- These strategies enhance encoding, remote retrieval,
- and strengthen memory consolidation,
- especially when linked with elaboration,
- the process of connecting new information to what you
- already understand.
- Retrieval practice is a strategy in which you actively
- recall information from memory.
- It is a form of self-testing as a study strategy.
- Let's consider an example of this.
- A student is learning about photosynthesis.
- After reading a passage about photosynthesis,
- a student closes their notebook and writes down everything
- they remember.
- They then check for accuracy and fill in the gaps in recall
- and understanding.
- This immediately puts the new information you learn to work
- by restating the new concepts in your own words.
- It also requires you to use your newly achieved
- understanding as a foundation by adding the misinformation
- afterwards.
- This works by strengthening neural pathways for accessing
- information.
- When you retrieve a memory,
- neurons that represent the parts of that memory fire
- together.
- This repeated activation strengthens the synaptic
- connections between those neurons.
- This makes memory easier to recall in the future.
- Another strategy is called spaced repetition.
- This has to do with how often we review the content.
- Spaced repetition is a study technique where information is
- reviewed at increasing intervals of time.
- The goal is to review information before it's forgotten,
- strengthening memory, and improving long-term retention.
- It's essentially the opposite of cramming.
- For example,
- a teacher may help students by reviewing key vocabulary
- from a unit every few days or using mini quizzes instead of
- cramming before a test.
- Here's a sample timeline of possible actions.
- On day one, study the material.
- On day two or three, quiz yourself without notes.
- By day five, try it again.
- If you recall most of it,
- increase the gap before the next review.
- Week two,
- use retrieval tests such as explain it to someone else,
- sketch a diagram or a timeline, test yourself again.
- At the point of one month,
- summarize or apply the information in a new context.
- From a brain science perspective,
- each time you recall information after delay,
- your brain reactivates the neural pathways where that
- memory is stored.
- It interrupts the potential to forget information.
- This process strengthens the connections between neurons,
- making it easier to recall the information in the future
- and helping to transfer it from short-term to long-term
- memory.
- Elaboration is an essential practice in building memories.
- Elaboration means that you expand on new information by
- connecting it to existing knowledge.
- Consider an example of the concept of photosynthesis.
- Instead of just memorizing the definition,
- the student creates a connection to the ideas that they
- already have.
- They might write it down and create something like this
- statement.
- Photosynthesis reminds me of how solar panels work.
- Just like solar panels capture sunlight to generate energy
- for a house,
- leaves capture sunlight to make energy for the plant.
- I also know that plants take in carbon dioxide and give up
- oxygen,
- so it's like they're cleaning the air while making their
- own food.
- According to neuroscience,
- elaboration strengthens learning by physically changing the
- brain.
- When students connect new ideas to what they already know,
- it activates networks of neurons.
- Repeated activation strengthens these connections,
- a process called synaptic plasticity,
- which helps move information into long-term memory and
- improves future recall.
- Interleaving is a practice strategy that may seem
- counterintuitive at first,
- as it goes against what many consider to be common sense
- learning.
- Rather than focusing on one type of problem at a time,
- interleaving involves mixing different types of problems or
- topics during practice.
- For example, in a math lesson,
- instead of giving students 10 perimeter problems in a row,
- you might provide a mixset that includes problems on area,
- perimeter, and volume.
- This approach encourages flexible thinking and helps
- students learn to distinguish between similar but distinct
- concepts.
- From a brain science perspective,
- interleaving works because it forces the brain to switch
- and compare,
- requiring learners to discriminate among concepts and apply
- knowledge in varied contexts.
- These frequent shifts demand deeper processing,
- which strengthens and reinforces neural pathways through
- repeated meaningful activation.
- Over time, this leads to stronger,
- more interconnected memory networks,
- supporting both long-term retention and transfer learning
- to new situations.
- These four strategies will provide you with a set of new
- and flexible tools to help you make your study and review
- time more effective.
- You may want to look into other strategies,
- such as dual coding,
- using concrete examples to model abstract ideas,
- and engaging metacognition,
- where you reflect on how you constructed your new ideas.
- By moving beyond repetition and instead using strategies
- that engage meaning, encourage recall,
- and strengthen connections,
- teachers can help students store information in long-term
- memory and actually use it later.
- Thank you for listening.
