eCoaching Tip 61 Steps in Memory-Making: What Teaching Behaviors Make a Difference
Remembering knowledge. Are you aware of the your teaching behaviors that make a difference in what students actually remember over time? This tip suggests some behaviors that can make a difference.
What do you think the percentage of the key concepts in your course that your learners integrate into useful knowledge? Do you think it is10%, 30%, 50%, or maybe even 80%? How confident are you about your estimate?
Data on exactly what students master during a course is difficult to obtain, but we do have a couple of data points. There is data that summarizes results from a test on core physics concepts from students in 14 different traditional lecture-based courses. This research suggests that the mastery of core concepts from lecture-based physics courses is consistently about 30% or less (Hake, 1998 in Weiman, 2008). Are you surprised that it is that high? Or that low?
Does this mean that students’ memories aren’t working very well? Would you agree with the Queen’s observation to Alice in L. Carroll’s Through the Looking-Glass, that we all have poor memories, particularly if they only work backwards? (Recall that the Queen could remember forward as well.) Well, probably not.
What this data probably means is that lectures are inefficient tools for developing mastery of concepts. Why might this be so? And, would we get similar results from students in online courses?
Using a Memory Process Model to Increase Learning
This tip is about the steps in creating long-term memories and using a memory process model to increase the percentage of learned concepts in our students. This is the question for you. What change(s) might I make the learning experiences in my course to increase the likelihood that students will integrate and apply core concepts?
A Look at a Memory-Making Process Model
How does memory work? Is it a one-time event or a series of events? Here are two useful definitions:
- Memory is the acquisition, storage, and retrieval of information. (Long, 2006)
- Memory is a linear process beginning with “sensory registration and finally leading to the consolidation of some information into long-term and/or remote memories.” (Loftus, 1996 in Long, 2006a). During the first stage–acquisition–an event is perceived and information about it is initially stored in our short-term memory. In the second stage—storageor retention–information is resident in long term memory. In the final stage–retrieval–memory is searched and pertinent information is retrieved and communicated.
So what does this mean? It definitely means that memory is not a one-time event.
Acquisition of knowledge — whether declarative or procedural knowledge — begins with a stimulus to our visual, auditory, or touching senses which results in sensory registration or memory. If we don’t pay any attention to the sensory input, it usually goes away. Moving the sensory data into short-term memory requires attention to the sensory inputs. Once the data is in short term memory, we need to encode and organize the data and move it into long-term memory. This step results in the knowledge being integrated and connected with other memories in long-term memory. (Long, 2006b adapting Loftus, 1996 model.) Once data is in long term memory it may be available for retrieval, or it may not, depending on how much it is used.
Check out the transcript for a diagram of the steps in the making of memories:
Note the approximate time for data to reside in sensory memory, and then be encoded in short tem memory and moved into long-term memory (Atkinson-Shiffrin, 1968). Since making memories takes time, attention and processing, it reinforces the need to build attention and processing time for encoding core facts, concepts and applications.
Definitions of each of these process points are at the end of the tip transcript for those of you who would like a little more clarification on each of these memory process events.
Teaching Strategies with the Memory-Making Model
At this point, let’s go back to the question for the tip. What teaching strategies are important to use for the students to master concepts? Here are a couple of strategies for you to consider.
We often design our online courses on a weekly basis. In fact, one of the ecoaching tips encourages setting up a weekly rhythmfor your course, mapping to the topics and modules within a course.
Thinking about memory as a linear process with at least 3 to 5 steps suggests strategies such as the following:
- Structurethe initial learning of core concepts into steps, creating experiences that ensure processing time for stimulus, sensory registration steps. This approach supports the acquisition step, requiring attention to the stimuli.
- Ask questions such as, “What “caught your eye?” Had you “heard” or “talked” about ideas such as these before?
- Engage the learners with the concepts, helping them in making connections and relationships to existing or earlier concepts. These activities help to move knowledge into short-term memory, and help to organize and encode the information so that it moves into long-term memory, supporting the retention stage.
- Ask questions or design dialogue experiences that elicit engagement, such as, “Can you describe how these concepts might be linked or related to other memories or knowledge that you have?” What do you know already that is similar or different from these ideas?
- Do you see a pattern emerging in this data? Can you draw a map with your team colleague showing the relationship of these data?
- Is there anything that is confusing or strange about how these ideas, processes, actions relate to each other? Are there cause-effect relationships here? Or other possible associations?
- Consolidateideas with opportunities for creative use of the concepts in complex unstructured contexts
- Ask questions, such as, “Can you reproduce, write, describe what those ideas mean to you?”This is a great use of the student blogs, by the way.
- Have the students apply the ideas in a simple to more complex scenario, so they can see the application of the concept and its probable relationship to earlier, similar concepts.
Then encourage students and yourself to refer to key concepts regularly as the course proceeds and find linkages and connections in current happenings. Each time the concepts are applied, or discussed as occurring in other contexts helps the learner to build a richer concept.
Can Sleeping Help the Encoding of Memories?
Eons ago when I was in college scientists rejected vehemently any possibility that we might be able to learn as we sleep. It now appears that while we might not learn new things while we sleep, that sleeping is very important to learning and memory. Researchers are still working on determining precisely how the brain strengthens and enhances memories but what does appear certain is that “Sleep does something to improve memory that being awake does not do.” The article concludes by saying that “Sleep makes memories stronger, and it even appears to weed out irrelevant details and background information so that only the important pieces remain.” (Stickgold & Ellenbogen, 2008, p. 24)
This finding suggests that we can increase our mastery of concepts by getting more sleep. That is a welcome finding for all of us. Imagine this instruction to our students. Read the instructions on solving quadratic equations, solve or work on 2 or 3 of these problems and then take a 20-minute nap.
Our memories work in complex ways. We are still learning exactly how they work. But what we do know is that memory and learning take time with repeated exposures and practice. And now we know as well, that it is probably helpful to sleep regularly.
We also know that our memories work more or less well most of the time, but that they don’t always work the way we wish they might. And they definitely only work backwards, unlike Carroll’s Queen who gets giddy from working with her memories that go forward!
Background – Memory Stages and Process Definitions From Long (2006a)
- Stimulus- Sensory Registration. In this step an event or object is perceived, such as seeing, hearing, reading, touching, moving.
- Attention -Short-Term Memory. In this step, sufficient attention is devoted to an event or object that information moves into “temporary storage.” Short-term memory has limited capacity and thus information or knowledge must be consolidated, encoded and stored quickly or it is lost.
- Consolidation-Retrieval into and from Long-Term Memory. Long-term Memoryis “memory that has been consolidated or stored so that it is available after distraction.”
- Remote Memory. Represents the storehouse of information that was acquired early and serves as the foundation for later memories.
