Knowledge, Like Water, Will Slip Between Our Fingers Unless.

When you cup your hands and use them to scoop up a drink of water, how long can you hold the water before it seeps between your fingers and out of your hands? Some can hold onto the water longer than others, but eventually the water slips from everyone’s hands. So, it is with our memory. We hear a name or phone number or read a story and for a bit of time we remember these. However, after a bit of time, that length of time varies with the person, recall of the name and phone number and the details of the story slip from our memory like water between our fingers. Short-term memory is only that, good for a bit of time. If we want to remember things for a longer stretch of time, we need to build long-term memory. We can build memories if we choose to do so.

What do we know?

We consider memory to be a natural phenomenon for keeping track of things. In everyday life, we have hundreds of micro experiences every day. These are things we see, and hear, and do as part of daily living. Yet we remember very few, because they were insignificant and occurred quickly and without reason to become longer memory. Our brains are not intended to remember everything we see, or hear, or do because there are thousands of these minutiae every day. Consider what it would be like inside your head if your brain were constantly trying to make sense of every detail in every second of your life. Happily, no one knows what your head would be like because this does not happen naturally. Instead, our brain sheds the minutiae in short order. Forgetting is as natural as remembering. Unless we actively work to build memory.

Being a student in school may build many memories but schooling itself does a poor job of teaching students how to remember. Our curricular program for every grade level and every course is industrial in nature. A teacher organizes units of instruction and teaches them one after the other. Sadly, schooling is assembly line instruction, and the conveyor belt only stops at graduation. The daisy chain organization of curriculum assumes that some of what a child learns at an earlier age will relate to or be applied in a later age. Certainly, a child’s developing skill sets in phonics-based reading and use of arithmetic skills are used throughout school and later life. However, what the child reads in fourth grade or the math work the child did in sixth grade are stand-alone assignments. 

Case in point – why do children in the United States typically study US history in grades 5, 8, and 10? The casual answer is that by teaching it again in 8th and 10th grade children develop a deeper understanding of their national story. If that were true, why do so many children have trouble on tests of US history? It is the most repeated curriculum in PK-12 yet ask any adult the name of the 8th US President or the relationship between the American Revolution and the War of 1812 or the effect of the Smoot-Hawley Act and you will wait a long time for answers. Are these important to remember? Maybe not, but they are indicative of how we treat this three-peat taught curriculum. Most American adults cannot pass the Immigration Service civics test. We are illiterate about our national story. So much for teaching children how to remember.

Being smart in school by remembering what you learn should not be a secret – help every child to be as smart as they can be. We need to teach children all the “secrets.”

Long ago and before the Internet’s instant access to information, knowledge was power. People who knew things and could do use their knowledge had advantages over people who did not know. Sadly, schools and teaching were a matter of “teachers know and children do not know – and only the smartest children learn what teachers know.” Too many of us experienced this in school.

Today our teachers’ job is to cause all children to learn what teachers know. A first-grade teacher’s job is to cause all first-grade children to learn the first-grade curriculum. A chemistry teacher’s job is to cause chemistry students to learn chemistry. This is teaching with an “I will do everything in my ethical abilities to teach my children what they need to know and do.”

Memory work is not easy, and it is not intuitive for all children. If a child has natural memorization ability, great! For children who need help memorizing, teach them how to remember. This mandate and constantly needs adaptive practice in every PK-12 classroom. We do not teach how to study and remember in elementary school and never again in middle and high school. We teach and practice these abilities in every classroom.

What to do better.

Start by acknowledging the current state of learning and remembering. We do not teach for long term memory. We do not teach children how to build long term memory, and our classroom practices do not build memory for the long-term. We talk about the importance of building, recalling, and using background knowledge but do not teach children how to recall and use what they have been taught.

Be intentional. Building recall does not take as much time and effort as reteaching what children have forgotten. “Children, we are going to learn how to improve our memory.”

  • Use recall events. Tell children “Before the next chapter or unit test, we are going to do things to help you remember what you are learning. These small activities will strengthen your memory of what you are learning before our usual tests.” Every several days have children “Tell me about the story we have been reading? I want to hear what you recall and your thoughts about the main characters, the plot, and where you think this story is going.” At the start, be non-evaluative and over time expect children to develop correct details. Have children tell each other about steps they have been taught to use in checking their multiplication problems. Do not just do the steps but explain why each step is mathematically important. Have children hum the song they are learning or restate the safety rules for using a turning wheel for pottery. Work on recalling the essential things in the current chapter or unit or story or class activity. Then, do it again next week.
  • Use non-graded retesting. Tell children “Frequent review of what you learned and was in a recent test helps you to remember what you learned. So, we will have several follow-up tests of that same information. The follow-up tests will not be graded, because we are taking these tests to build memory of what you already were tested on.”
  • Use flash cards. Have children make their own flash cards. This applies to all K-12 children in all subjects. Cards can be created to build recall for vocabulary and definitions, events with dates and names, series of steps in a process, and to explain significance. The practice of creating flash cards alone builds memory; the use of flash cards builds stronger memory.

No child is too old for flash cards! At age 77 I am relearning French language and flash cards are part of the routine.

  • Use intermittent review. Students tend to cram for tests. Tell children “Better practice is scheduled or intermittent review over time. Do not leave studying for a test until the last night before test day.” The recall events described above practice intermittent study. Use intermittent for end of course and end-of-year tests. Next month do a review of essential content and skills taught the previous month. Run through last month’s flash cards. Three months hence do it again. The reason is this – background knowledge, like water in your cupped hands, eventually will slip away if you do review/refill it.
  • Use memory organizers. Tell children “It is okay to create your own ways of remembering what you don’t want to forget.” Teach them how to draw a concept map linking ideas together as supporting details. Teach them associations to link new learning to what they know. Teach them how to create a rhyming word phrase so that each word reminds them of ideas and strings of ideas they want to remember. Teach them to use a simple sentence where each word reminds them of an idea or string of ideas they want to remember.

The Big Duh!

Return to a variation of Cartesian logic. “If I taught something to children and they did not learn it, did I really teach them anything?” Possibly. Instead posit, “If I taught children and did not teach them how to remember what I taught them, did I really teach anything?” Indeed, not. If you expect children to remember what you taught them, teach them how to remember.

Teach Less, Teach Better, Teach It Again and Again

“I taught a lesson to my students.  They should have learned it.” 

Some students learned “it”, and some did not.  And some tuned out and were not mentally present for learning.  Walk the hallways of any school.  Stop to look in and watch the teaching and learning act in motion.  We see the teaching.  We assume the learning.  At the end of any lesson, we may hear the teacher sigh with this assumption.  “There.  I taught it.   They should have learned it”.  Or was it exasperation.

What do we know?

We don’t remember all that we are taught for very long.  This is a fact.  Hermann Ebbinghauss, a German psychologist, explored memory and why we forget.  His work in the 1880s has been replicated and validated over time.  His “forgetting curve” is instructive today.

“We forget 50% of the new information we are presented within 24 hours and 90% of that new information within a week.”

Perhaps the above statement should be emblazoned on the back wall of every classroom for teachers to constantly read as they teach.

https://www.mindtools.com/a9wjrjw/ebbinghauss-forgetting-curve

Ebbinghauss’ “forgetting curve” corresponds with Edgar Dale’s “Cone of Experience”.  In the 1960s Dale posited what he called the “Cone of Experience”.  Dale examined how people receive information.  He developed a model portraying the effectiveness of the mode for presenting new information and memory.  The isolated act of reading was the least effective while designing and making a presentation was the most effective. 

Later, misinterpreters of Dale’s work relabeled it the “Cone of Remembering” and this misinterpretation has been repeated until many believe it as factual.  This is the misinterpretation.

WE REMEMBER

10% of what we read.

20% of what we hear.

30% of what we see.

50% of what we see and hear.

70% of what we discuss with others.

80% of what we personally experience.

95% or what we teach others.

This is Dale’s Cone of Experience.

Presentation modes of verbal and visual symbols (words and graphics) are impersonal and less well remembered while the four experiential activities at the bottom of the cone require personal engagement and result in better retention.

Ebbinghauss and Dale inform us that memory is fickle and short-lived if it is isolated and left alone.

Capitalize on learning and make it memorable.

Further, Ebbinghauss’ research tells us that we can reduce the decline of memory by using several instructional strategies.  He found these to reduce forgetting.

  • Reinforce content, skills, and dispositions about learning regularly.  We know from retention theory that if we want information or skills to be accessible in short-term memory, students need 5-7 repetitions of mentally or physically working with they are to remember.  Theory tells us that 18 – 20 repetitions are required to create long-term retention.  If the biggest loss of memory is within one day, repetition must be at least daily to begin building memory.  This clearly is Ebbinghauss.
Memory Recall and Retrieval System

Consider automaticity of math facts.  We teach and drill children to learn addition, subtraction, multiplication and division math facts in the primary grades.  Then in the upper elementary and middle level grades we assume these facts are secured memory for all students.  In fact, they are not.  If we want to ensure automaticity, repeat episodes of the several times every year.  Make a game of it but do it.  Assumptions that children remember almost always leads to problems.

  • Presentation matters for clarity of what is to be remembered.  Make the new information easier to comprehend and absorb.  Assign smaller chunks of material to be read or watched.  Use visuals and graphics to assist students to make a clearer understanding of new information.  Build outlines, maps, and graphic organizers for students to link new information to what they already know.  This clearly is Dale.

  • Make learning relevant and personal.  Motivation theory tells us that when students see themselves using new information or skills, they are more receptive to new learning and invested in remembering it.  Personalizing new learning gives students a purpose for learning and remembering it.
  • Make learning active not passive.  Use as many modalities for students to engage with new learning as are reasonable.  Approach new learning verbally – say it, write it, interpret it in a different language.  Approach it creatively – draw it, paint it, sculpt it, build it, sign it, and act it out.  Be careful not to let the projection of new learning become more important that the new learning itself.

What to do – Teach it, Teach it better, and Teach it again and again.

Teach less.  A grade level or subject area curriculum always contain more learning than can be accomplished within the confines of school year.  A teacher who says, “I taught everything in my curriculum or course guide” either has Cliffs Notes as a guide or is settling for very minimal student achievement in the end of year assessments.  This is not a license to discard a curriculum or course guide, but to carefully select the essential content information, skills, and dispositions that all students must learn and remember.  Both words are critical – learn and remember. 

Teach it better.  Use sound theories of instruction to build student retention and use of what they learn.  Chunk new learning for clarity.  Provide organizers of connecting new to secured learning.  Use multiple examples to help challenged learners find a connection to new learning.  The use of sound theories to teach essential new learning by itself will propel student achievement.

Make it meaningful.  Attach new learning to what students already know.  Attach new learning to the interests of the students, their families, and their community.  Attach new learning to what students will be learning and doing in their educational and career futures.  Once a child finds a purpose for learning, get out her way and simply coach her along the way.

Teach it again and again.  We parse our curriculum into units and chapters and almost never reteach or return to a unit or chapter once we complete it.  Then we wonder why students at the end of the year cannot recall with completeness or clarity what they learned at the beginning.  Take the time to repeat a chapter review from several chapters ago.  Check to know what students remember and can to with completeness and clarity.  If that knowledge or skill is essential, teach it again.  Do this rear-view mirror chapter review throughout the year.  You will see better student performances on end of year tests and future teachers of your students will be amazed at their longer-term memory.
