Transcript
- Welcome to New Teacher Talk.
- I'm Dr.
- Anna Quinzio-Zafran.
- And I'm Dr.
- Beth Wilkins.
- We are back with the second episode in our Science of
- Learning series with Dr.
- Ken King,
- where we translate the research on learning into moves you
- can make on Monday morning.
- Today's topic is retrieval practice,
- the surprisingly simple act of having students pull
- information from memory rather than just review it.
- Ken explains why bringing information to mind is one of the
- most powerful ways to make it stick,
- and how to use it without adding to your grading pile.
- Stay with us.
- Let's talk about retrieval and how that works better than
- reviewing things when learning takes place.
- To start with,
- I'd like you to consider this statement as a place to begin
- the podcast.
- Studying means putting information into the brain
- repeatedly.
- That belief drives many common study habits: rereading
- notes, highlighting textbooks, watching lecture videos,
- and, and reviewing slides over and over.
- These strategies can feel productive because students
- become familiar with the material,
- but familiarity is not the same thing as remembering.
- This is one of the most important misconceptions new
- teachers need to recognize.
- Students may look at information again and again and feel
- as though they know it,
- but when they are asked to explain without notes,
- apply it to a new problem, or recall it a week later,
- the learning may not be there.
- In this episode, we're going to look at retrieval practice,
- a learning strategy that shifts attention from putting
- information into memory,
- pulling information back out of memory.
- That shift changes how we think about studying, homework,
- review, questioning, and assessment.
- By the end of this presentation,
- you may come to better appreciate that the most important
- question in learning may not be how many times have
- students seen this information,
- it may be how many times have they successfully retrieved
- it from memory?
- My name is Ken King,
- and I'm a professor of education at Aurora University in
- Aurora, Illinois.
- Today, I'm going to discuss retrieval practice.
- I'll explain the learning science that supports this
- instructional strategy and share several practical ways
- teachers can incorporate this into classroom instruction.
- To begin with,
- let's answer the question: What is retrieval practice?
- Well,
- retrieval practice is a learning strategy in which students
- actively recall information from memory rather than simply
- reviewing it.
- The act of bringing information to mind strengthens memory
- and makes future recall easier.
- Simply put,
- retrieval practice means trying to remember what you have
- learned without looking at the answer first.
- This is different from rereading notes,
- highlighting a textbook, or watching a lecture again.
- Those activities may expose students to information,
- but retrieval practice asks students to reconstruct
- information from memory.
- That reconstruction matters.
- Learning is not strengthened primarily by putting
- information into memory again and again.
- Learning is strengthened when students repeatedly bring
- information back out of memory.
- I'd like to introduce some essential learning science
- ideas.
- There are several ideas that are going to help explain why
- retrieval practice is so powerful.
- First of all,
- retrieval practice is connected to the testing effect.
- Many teachers think that quizzes simply measure learning.
- Cognitive science shows that retrieval itself causes
- learning to take place.
- Students who spend time recalling information often
- remember more later than students who spend the same amount
- of time restudying information.
- The benefit comes from the act of retrieval,
- not simply from the quiz grade.
- In this way, a quiz can be instruction,
- not just assessment.
- Authors such as Roediger & Karpicke and Roediger & Butler
- both have done research on this to confirm this idea.
- Secondly, retrieval works best when it's effortful.
- Easy review often feels productive,
- but effortful recall produces stronger long-term learning.
- Students have to search memory, organize what they know,
- and reconstruct the answer.
- That effort can feel uncomfortable but is often a sign that
- learning is happening.
- For teachers,
- this means the productive struggle during retrieval should
- not be automatically interpreted as failure.
- If the task is within reach,
- the challenge itself may be exactly what strengthens
- learning.
- Third point,
- forgetting can actually support learning when it's followed
- by successful retrieval.
- If a student recalls information immediately after a
- lesson, the task may be too easy.
- But if they retrieve it a few days later,
- after some forgetting has occurred,
- the act of remembering becomes more powerful.
- Retrieval helps slow future forgetting and makes learning
- more durable.
- This is why returning to important ideas over time can be
- more effective than reviewing them only right after
- instruction.
- And finally,
- retrieval should match how students will use the
- information later.
- This idea is connected to transfer appropriate processing.
- If students will need to explain, apply, compare, solve,
- or discuss ideas,
- then retrieval practice should include those kinds of
- tasks.
- Students should not only practice recognizing correct
- answers,
- they should practice bringing ideas to mind in ways that
- reflect real academic use.
- Retrieval strengthens memory,
- but it also supports understanding and transfer when
- students retrieve knowledge in meaningful ways.
- Uh, there's another point to make, that, uh,
- sometimes teachers don't always use retrieval practice
- effectively.
- So the question is, if it's so powerful,
- why is it not used more consistently?
- One reason is that teachers and students often confuse
- performance with learning.
- During review,
- students may seem successful because the information is
- right in front of them.
- They can follow the teacher's explanation,
- recognize highlighted ideas,
- or answer questions immediately after reading it.
- But what students can do five minutes after instruction may
- not show what they will remember a week later.
- Brown, Roediger,
- and McDaniel describe this as an illusion of mastery.
- Students feel fluent with the material,
- but that fluency may not last.
- A second reason that retrieval feels harder than review is
- that students often prefer rereading because it feels
- smooth and familiar.
- Retrieval feels more demanding because students must work
- without support.
- They may pause, struggle.
- They may realize they don't know as much as they thought.
- Teachers can misread that struggle as a sign that retrieval
- is not working, when in fact,
- the challenge is often part of why retrieval works.
- A third reason is that many teachers inherit traditional
- views of assessment.
- Tests and quizzes are often treated as tools for grading
- rather than as tools for learning.
- As a result,
- teachers may save quizzes for the end of a unit instead of
- using short,
- low-stakes retrieval opportunities throughout instruction.
- Retrieval practice asks teachers to think and rethink about
- assessment.
- A question, a quiz, an exit assessment,
- or discussion prompt can help students learn,
- not merely show what they have learned.
- A fourth reason is the pressure to cover large amounts of
- curriculum.
- Retrieval can feel inefficient because it uses time to
- revisit older material.
- But if students forget what has already been taught,
- future instruction becomes harder.
- Time spent retrieving prior learning can make later
- teaching more effective.
- In this sense,
- retrieval may feel like it slows instruction today while
- helping prepare learning that will last through tomorrow.
- So in terms of instructional implications,
- what does this look like in the classroom?
- I'd like to offer some examples that show how teachers can
- use retrieval across grade levels and content areas.
- First example, frequent low-stakes quizzes.
- One simple strategy is to begin class with three to five
- questions and ask students to recall previous learning.
- These quizzes should be ungraded or minimally graded so
- students focus on remembering rather than earning points.
- For example,
- a fourth grade science teacher might begin class with three
- questions about ecosystems.
- What's a producer?
- What is a consumer?
- And why is sunlight important in a food web?
- Students answer from memory before the lesson begins.
- Then the teacher briefly reviews the responses and clears
- up misunderstandings.
- In a high school history class,
- a teacher might ask these questions.
- What were two causes of the Great Depression?
- What was the purpose of the New Deal?
- And which groups benefited most from New Deal programs?
- The goal is not to create more grades.
- The goal is to create more opportunities for students to
- pull important information from memory.
- Another approach is that every retrieval opportunity
- becomes a learning opportunity.
- I'd like to introduce the example of a brain dump.
- A brain dump asks students to put away all materials and
- write everything they can remember about a topic for two or
- three minutes.
- For example,
- a seventh grade math teacher might ask students to write
- everything they remember about solving proportions before
- beginning a review lesson.
- Students might write about equivalent ratios,
- cross multiplication, missing values,
- or checking whether two ratios are equal.
- The teacher can quickly see what students remember and
- where confusion remains.
- In a senior high school biology class,
- students might write everything they remember about
- photosynthesis before beginning a lesson on cellular
- respiration.
- That short retrieval activity reactivates prior knowledge
- that will support new learning.
- Brain dumps are useful because they make student thinking
- visible.
- They also help students notice gaps in their own
- understanding.
- Instead of assuming that they know the material because it
- looks familiar,
- students discover what they can actually retrieve.
- Another example, again involving brain dumps,
- they can strengthen memory while giving teachers useful
- information about student learning.
- So this is an example of a delayed recall activity.
- Delayed recall means that we return to important content
- after time has passed.
- Instead of reviewing only yesterday's lesson,
- teachers intentionally ask students to retrieve ideas from
- last week, last month, or earlier in the semester.
- For example,
- an elementary teacher who introduces multiplication
- strategies in September might include one multiplication
- retrieval question each week throughout the semester.
- A middle school English teacher might ask students in
- November to explain plot structure concepts introduced in
- September.
- Or a high school chemistry teacher might begin a unit on
- chemical reactions by asking students to recall atomic
- structure concepts from several weeks earlier.
- In each case,
- students must work harder because the material is no longer
- fresh.
- That effort is valuable.
- When students successfully retrieve information after some
- forgetting,
- the memory becomes stronger and more resistant to future
- forgetting.
- Another teacher takeaway,
- if students have forgotten a little,
- retrieval may become more powerful, not less.
- I'll offer the example of using oral retrieval discussions.
- Retrieval does not always have to be written.
- Students can also retrieve through speaking.
- A second grade teacher might ask students to turn to a
- partner and explain the water cycle without looking at
- classroom posters.
- In grade six,
- a social studies teacher might ask students to explain why
- ancient civilizations often develop near rivers before
- opening their notes.
- In high school, a government teacher might suggest,
- "Turn to a partner and explain the difference between the
- legislative and executive branches.
- You have one minute." Speaking from memory requires
- students retrieve information, organize it,
- and explain it clearly.
- It also helps teachers hear misconceptions that might
- remain hidden during silent review.
- So a key takeaway,
- understanding becomes visible when students explain ideas
- without support.
- As we wrap things up,
- retrieval practice does not require new curricula,
- expensive technology, or lengthy assessment systems.
- A two-minute brain dump, a three-question warm-up,
- a partner explanation,
- or a delayed recall prompt can all create meaningful
- learning opportunities.
- That is one reason that retrieval practice is such a
- powerful strategy for beginning teachers.
- It's grounded in strong research, easy to implement,
- and adaptable across grade levels and content areas.
- It can become part of everyday instruction rather than an
- occasional special activity.
- Framed this way, the review becomes retrieval.
- Assessment becomes part of instruction.
- Rather than asking,
- "How can I get students to see this information?" we might
- ask,
- "How can I get students to remember it again?" That simple
- shift can transform how we design lessons, homework,
- review activities, and assessment.
- I provided a reading list to accompany this podcast.
- You'll find that Agarwal & Bain's book, Powerful Teaching,
- is a great read and offers important insights for how
- learning takes place and how you can use the information to
- make a difference.
- For the same reason,
- I would also recommend the book Make It Stick: The Science
- of Successful Teaching by Brown, Roediger,
- McDaniel as another excellent resource.
