I Analyzed 13 TED Talks on Improving Your Memory — Here’s the Quintessence — from learntrepreneurs.com by Eva Keiffenheim
How you can make the most out of your brain.

Excerpt:

In her talk, brain researcher and professor Lara Boyds explains what science currently knows about neuroplasticity. In essence, your brain can change in three ways.

Change 1 — Increase chemical signalling
Your brain works by sending chemicals signals from cell to cell, so-called neurons. This transfer triggers actions and reactions. To support learning your brain can increase the concentration of these signals between your neurons. Chemical signalling is related to your short-term memory.

Change 2 — Alter the physical structure
During learning, the connections between neurons change. In the first change, your brain’s structure stays the same. Here, your brain’s physical structure changes — which takes more time. That’s why altering the physical structure influences your long-term memory.

For example, research shows that London taxi cab drivers who actually have to memorize a map of London to get their taxicab license have larger brain regions devoted to spatial or mapping memories.

Change 3 — Alter brain function
This one is crucial (and will also be mentioned in the following talks). When you use a brain region, it becomes more and more accessible. Whenever you access a specific memory, it becomes easier and easier to use again.

But Boyd’s talk doesn’t stop here. She further explores what limits or facilitates neuroplasticity. She researches how people can recover from brain damages such as a stroke and developed therapies that prime or prepare the brain to learn — including simulation, exercise and robotics.

Her research is also helpful for healthy brains — here are the two most important lessons:

The primary driver of change in your brain is your behaviour.

There is no one size fits all approach to learning.

 


From DSC:
This is so important. It’s the underlying cognitive science/psychology involved in the posting I recently created that was entitled, “What are the ramifications of having cognitive “highways in our minds?” It occurs to me that patience, grace, forgiveness, work, new habits, and more are required here.

From DSC:
What are the cognitive “highways” within our minds?

I’ve been thinking a lot about highways recently. Not because it’s construction season (quite yet) here in Michigan (USA), but because I’ve been reflecting upon how many of us build cognitive highways within our minds. The highways that I’m referring to are our well-trodden routes of thinking that we quickly default/resort to. Such well-trodden pathways in our minds get built over time…as we build our habits and/or our ways of thinking about things. Sometimes these routes get built without our even recognizing that new construction zones are already in place.

Those involved with cognitive psychology will connect instantly with what I’m saying here. Those who have studied memory, retrieval practice, how people learn, etc. will know what I’m referring to. 

But instead of a teaching and learning related origin, I got to thinking about this topic due to some recent faith-based conversations instead. These conversations revolved around such questions as:

  • What makes our old selves different from our new selves? (2 Corinthians 5:17)
  • What does it mean to be transformed by the “renewing of our minds?” (Romans 12:2)
  • When a Christian says, “Keep your eyes on Christ” — what does that really mean and look like (practically speaking)?

For me, at least a part of the answers to those questions has to do with what’s occupying my thought life. I don’t know what it means to keep my eyes on Christ, as I can’t see Him. But I do understand what it means to keep my thoughts on what Christ said and/or did…or on the kinds of things that Philippians 4:8 suggests that we think about. No wonder that we often hear the encouragement to be in the Word…as I think that new cognitive highways get created in our minds as we read the Bible. That is, we begin to look at things differently. We take on different perspectives.

The ramifications of this idea are huge:

  • We can’t replace an old highway by ourselves. It takes others to help us out…to teach us new ways of thinking.
  • We sometimes have to unlearn some things. It took time to learn our original perspective on those things, and it will likely be a process for new learning to occur and replace the former way of thinking about those topics.
  • This idea relates to addictions as well. It takes time for addicts to build up their habits/cravings…and it takes time to replace those habits/cravings with more positive ones. One — or one’s family, partner/significant other, and friends — should not expect instant change. Change takes time, and therefore patience and grace are required. This goes for the teachers/faculty members, coaches, principals, pastors, policemen/women, judges, etc. that a person may interact with as well over time. (Hmmm…come to think of it, it sounds like some other relationships may be involved here at times also. Certainly, God knows that He needs to be patient with us — often, He has no choice. Our spouses know this as well and we know that about them too.)
  • Christians, who also struggle with addictions and go to the hospital er…the church rather, take time to change their thoughts, habits, and perspectives. Just as the rebuilding of a physical highway takes time, so it takes time to build new highways (patterns of thinking and responses) in our minds. So the former/old highways may still be around for a while yet, but the new ones are being built and getting stronger every day.
  • Sometimes we need to re-route certain thoughts. Or I suppose another way to think about this is to use the metaphor of “changing the tapes” being played in our minds. Like old cassette tapes, we need to reject some tapes/messages and insert some new ones.

What are the cognitive highways within your own mind? How can you be patient with others (that you want to see change occur within) inside of your own life?

Anyway, thanks for reading this posting. May you and yours be blessed on this day. Have a great week and weekend!

How Art Class Became a Rare Bright Spot for Students and Families During the Pandemic — from edsurge.com by Daniel Lempres

Excerpt:

When schools went remote two years ago, the National Art Education Association (NAEA) was quick to offer guidance on how best to reach students who have experienced trauma. They offered strategies for remote learning, as well as mental and emotional wellbeing.

Now more than ever, art educators must employ the tenets of social emotional learning, the NAEA says. In a recent report, the association recommended trauma-informed teaching strategies to promote mental health through self-expression—for their students’ sake and their own.

But with asynchronous lessons and virtual events, the amount of parental participation skyrocketed, she says.

A report of the AEI-Brookings Working Group on Childhood in the United States

Excerpts (emphasis DSC):

The future of America rests in part on how the country prepares the next generation to live and to lead. Childhood is a consequential and cost-effective time to make investments that last a lifetime. Yet, many children in the United States do not have the resources or relationships they need to build a strong foundation for their future.

Yet, one area of resounding agreement among this diverse group is the need to rebalance national investments toward children. What follows is a consensus report on our conclusions, laying out actionable policies across a range of policy areas to improve the life of every child in the United States.

The case for nurturing an infant -- a recording by Dr. Kate Christian

The case for nurturing an infant — from grcc.hosted.panopto.com by Dr. Kate Christian

Yes, Kate is one of my wonderful, talented, intelligent, and compassionate sisters! She is a Professor of Psychology at the Grand Rapids Community College.

Notes:

TITLE/THEME:   The relationship between infant nurturance and the developing brain, and implications for long term physical and mental health

Question: How much time should you spend in direct interaction with your infant? 

  1. CONCERNS: Many people are concerned that paying too much attention to an infant will have negative consequences. (Words like “spoiled”, “dependent”, “mama’s boy”, etc.) 
    1. John Watson (1878-1958) wrote “The Psychological Care of Infant and Child” in 1928, arguing that infants and children should be treated like young adults, and that too much love and affection were damaging—children should not be kissed, hugged, or touched. Ideas such as strict feeding schedules (withholding nourishment if not on schedule) for infants were not uncommon during the first half of the twentieth century. 
    2. Behaviorist views emphasize rewards and punishment in shaping behavior. Today few behaviorists would argue for limiting affection. However, some may argue to let an infant “cry it out”, citing research that indicates infants can learn to self-soothe by about 7 months.
  2. HOWEVER, a wealth of evidence (theoretical, observations, animal studies, and neuroscience research) shows that nurturing an infant provides long term physical and mental health benefits. 
    1. PSYCHOANALYTIC theory:
      1. Sigmund Freud (1836-1959) coined the term “schizophrenogenic mothers”, claiming that especially for male infants, a failure of attachment to the mother could lead to schizophrenia, and that the mother’s lack of sensitive, caring behavior was the cause of attachment failure.
      2. Erik Erikson (1902-1994) established the idea of a psychosocial “crisis” during infancy in which the infant either learns to develop a sense of trust in the world (due to sensitive caregiving) or mistrust (due to unreliable, unpredictable or abusive care). 
      3. John Bowlby (1907-1990) is the founder of Attachment Theory, which maintains that caregiving in the first year of life sets up an unconscious, internal working model of relationships that shapes behavior and thoughts later in life. (Mary Ainsworth (1913-1999) came up with a measurement tool.) Secure attachment develops from sensitive, responsive caregiving, according to Ainsworth and Bowlby.Support for attachment theory varies, and many developmental psychologists today believe that early attachment is moderately predictive of later outcomes. (Things like divorce or death of a parent change the internal working model, or therapy, etc.) But infants with a secure attachment are more likely to explore their environment and be INDEPENDENT!!
    2. OBSERVATIONS: Rene Spitz (1887-1974) compared infants raised in orphanages to infants whose mothers were with them but in prison (in the 1940’s), the primary difference being maternal vs. professional nurse care. When the infants were first placed in the orphanage, Spitz found that for the 1st two months of separation, the infant would weep, scream, and/or be unapproachable. After 3 months, the infant would often become listless, lethargic, and demonstrated bizarre finger movements, and couldn’t sit or talk. 38% of the infants in the orphanage developed marasmus and died within 2 years, whereas all of the infants raised in prison with their moms were alive at follow up (age 5).  You can see video Click Here of infants who appeared dull and listless, or engaged in rocking back and forth or beating their heads on the crib. The infants were well fed and diapers changed, etc, but they had negligible physical touch or affection.Infants in institutions are less likely to play and interact with toys in the environment: Click here for video examples
      .
    3. ANIMAL STUDIES:
    1. Rat pups   The amount of licking given to rat pups by maternal dams has predicted the level of anxiousness (vs. relaxation) in the rat, as well as inhibitory (vs. exploratory) behavior on a maze. Research has shown there are changes in neurobiology (such as hormones and brain receptors in the amygdala) that impact how the rats react to stress. In other words, the more the mother rat licks/grooms the pup, the more she sets up that rat to stay calm and resilient in the face of stress, and to feel confident to explore the environment.  nih.gov
    2. Harlow’s monkeys Monkeys in Harry Harlow’s experiment chose to spend nearly 23 hours a day in close contact with an artificial monkey that was covered in soft cloth and had big eyes (vs. a wire mother than administered food and drink). 
    3. Rhesus monkeys: Neuroscientists have found changes in the basic architecture of the amygdala and areas in the limbic system among rhesus monkeys deprived of touch, eye contact, and adult nurturing during infancy. (p. 129 Marian Diamond, Ph.D.) 
  3. NEUROSCIENCE:
    1. Face-to-face interaction between infant and caregiver help wire the infant brain (use-dependent) and set up the basic architecture of the brain. Infants who experience positive interactions have a neurophysiological response (being smiled at calms the brain!) and neural connections that interact with biological hormones and systems regarding stress regulation get established in a positive way. This leads the infant to grow up better able to handle stress and adversity. 

Research using the ACE scale (adverse childhood experiences) found that children who face a great deal of adversity but are in relationally healthy, nurturing environments will show few long term negative effects (and the reverse is true—a child with even one ACE in an emotionally deprived environment will show significant poor outcomes).   (From Bruce Perry lecture) 

This infant nurturance also shapes the brain’s reward centers. Dr. Bruce Perry argues that infants deprived of nurturance grow up to feel dysregulated, and seek rewards in unhealthy behaviors (overeating/poor diet, substance use, thrill seeking, etc.) 

    1. Example: kangaroo care is the practice of holding an infant skin to skin, and it has been shown to increase weight gain among premature infants. 
    2. What about CELL PHONES?
      • Using a cell phone while caring for an infant has been shown to increase the risk of infant injury by 10%.
      • It also interferes with the face-to-face interaction needed for the neurobiological positive effects to occur!!
    3. Again… how much time to spend in direct interaction with an infant?
      • It doesn’t have to be 24/7, but most infants are not getting enough time. (Hunter gather—spend nearly all day in close proximity to adults, infant child care centers,  4:1 ratio)
      • Hold, sign, rock, touch, play together!
    4. But can’t you overdo it? Are you SURE you won’t spoil the infant or make him/her dependent?
      • There is virtually NO evidence to suggest that “too much” attention in the first year of life is harmful. (Again, you don’t have to spend every minute together… both you and the infant need breaks!) But this cultural perception that it is possible to “over nurture” an infant has got to change!!
    5. What about Co-Sleeping?
      • Worldwide, some form of co-sleeping is the norm.
      • A study found that in the U.S., infants who co-sleep grow up to be MORE independent (secure attachment) than those who don’t.
      • However, there are physical concerns, such as studies finding higher SIDS rates among infants who co-sleep. Also, if a parent is a deep sleeper, is drunk, or sleeps in a chair, if space between wall, etc, these are hazards.

BOTTOM LINE…. HOLD THAT BABY!!!

 

From DSC:
One of my sisters is a Professor of Psychology and she highly recommended that I check out the work of Dr. Bruce D. Perry. Below is an example video that was recorded on October 25, 2014 as part of the 25th Anniversary Chicago Humanities Festival, Journeys. I included some excerpted slides in this posting to give you a flavor of portions of this talk.

Description (emphasis DSC):

Each of us takes the same journey from birth to consciousness—but none of us recalls it. This early stage of life is crucial; Sigmund Freud famously obsessed over it, as do millions of parents every day. What goes on cognitively during that time, and what can parents—and other adults—do to further promote infant well-being? Join renowned psychiatrist Bruce D. Perry, recipient of the 2014 Dolores Kohl Education Prize, for this discussion of early-childhood brain development and its long-term importance.

Why the Science of Teaching Is Often Ignored — from chronicle.com by Beth McMurtrie
There’s a whole literature on what works. But it’s not making its way into the classroom.

Excerpts:

Yet, teaching reformers argue, the dangers of ignoring the expanding body of knowledge about teaching and learning are ever more apparent. Traditional teaching may have sufficed when college campuses were more ivory tower than lifeboat, educating future generations of scholars and other elites rather than trying to lift up a diverse group of students and prepare them for an increasingly complex world.

Studies have also shown that faculty members are more likely to try evidence-based teaching practices if they feel they have supportive colleagues and departments. Faculty learning communities can be particularly helpful, teaching experts say, because instructors meet regularly over a series of months to tackle complex challenges, often by exploring the research and experimenting with small changes to their teaching.

Reforming teaching evaluations so that they reflect the hard work of reading and reflecting on teaching scholarship is also a critical lever for change.

 

The Importance of Curiosity and Tension to Storytelling — from janefriedman.com by Stefan Emunds
Today’s post is excerpted from The Eight Crafts of Writing by Stefan Emunds (@StefanEmunds).

Excerpt:

To maintain reader curiosity, you can raise and answer multiple questions on multiple levels—for example, a story question, an act question, a chapter question, and a scene question. Try to keep two to three questions open at any given time. Raise two questions in your opening and answer one. Then, raise two new questions and answer one. Then raise two new questions and answer two.

Take the world of TV and movie writing: screenplays have seven or eight sequences, and each sequence begins with a challenge/question and ends with an answer—success or failure. You can do the same thing with chapters and acts.

You can have multiple questions going on at the same time

 

Growth Mindset Leadership & The Pygmalion Effect — from by Trevor Ragan and the Learning Lab; featuring Robert Rosenthal, Christine Rubie-Davies, and Michael Merznich. With thanks to Chris Church, Tenured Professor and prior Associate Dean of Academic Programs at the WMU-Cooley Law School
Our mindsets impact others more than we realize. As leaders, we can use this to improve the learning environment.

Excerpt:

We know that our individual mindsets (growth mindset & fixed mindset) can impact our capacity to grow. But how do our mindsets impact others?

Renowned researcher, Robert Rosenthal outlines his work and shows how our expectations can have a huge impact on the performance and development of the people around us.

Christine Rubie-Davies from the University of Auckland shows us how teacher expectations play a role in student development.

From DSC:
I highly recommend that all professors, teachers and student teachers, trainers — and even those supervising others — check this piece out! Nice work Trevor & Company! Below are some snapshots from this presentation.

The agenda for Trevor Ragan's presentation re: the Pygmalion Effect

 

Whatever you think your limits are...you're wrong.

 

There are many labels that we put on others -- and that has real consequences and ramifications...both positive and negative depending upon the label.

Teachers expectations of someone matters!

 

The Pygmalion Effect -- our labels and expectations can become self-fulfilling prophecies

 

Put the label of learner at the top! We can all grow and learn, even though we aren't all equally gifted in all disciplines.

 

Making VR a Reality in the Classroom — from er.educause.edu by Cat Flynn and Peter Frost
Faculty and staff at Southern New Hampshire University piloted virtual reality in an undergraduate psychology course to see if it can be an effective pedagogical tool.

Excerpt:

Meeting the Learning Needs of Gen Z and Beyond
While this study was conducted with current SNHU undergraduates, our team aimed to understand the implications of immersive learning for both today’s students and future learners.

Given Gen Z’s documented love for gaming and their desire for higher education to equip them with problem-solving and practical skills, VR provides a confluence of experiential learning and engagement.

From DSC:
Cost and COVID-19 are major issues here, but this is an interesting article nonetheless.

I think Virtual Reality (VR), Mixed Reality (MR), and Augmented Reality (AR) will play a significant role in the future of how we learn. It may take us some time to get there, but I believe that we will.

 

My Favorite Wonder Tools of 2020 — from wondertools.substack.com by Jeremy Caplan

Excerpts:

Here are a few things I loved in 2020:

Math Tango
If you have a little one, this app is a grand slam. Recommended by her teacher, Math Tango was a surprise favorite for my younger daughter, who started kindergarten this fall. She rarely used a screen until remote school began. She loves the app’s creative puzzles and she’s enjoyed learning lots of basic math. It’s $8/month or $50/year, for ages 5-10.

Seek
Point the app at a plant, flower, bug or animal and it magically identifies it. Depending on how close you are, how much light there is, and how good your phone’s camera is, results vary, but I was impressed.

Use the power of image recognition technology to identify the plants and animals all around you.

 

Interleaving: How Mixed Practice Can Boost Learning— from effectiviology.com

Excerpt:

Interleaving is a learning technique that involves mixing together different topics or forms of practice, in order to facilitate learning. For example, if a student uses interleaving while preparing for an exam, they can mix up different types of questions, rather than study only one type of question at a time.

Interleaving, which is sometimes referred to as mixed practice or varied practice, is contrasted with blocked practice (sometimes referred to as specific practice), which involves focusing on only a single topic or form of practice at a time.

Also see:

 Also see:

Excerpts:

Interleaving boosts learning by mixing up closely related topics, encouraging discrimination between similarities and differences. (Agarwal & Bain, p. 14)

It’s “re-arranging the order of retrieval opportunities during spacing without changing the content to be learned.”  It’s mixing up concepts. (Agarwal & Bain, pgs. 106-107).

Consider this basic example of practice problems in any math course:

Problem Set 1: AAAA BBBB CCCC DDDD [i.e., blocked practice]
Problem Set 2: ABCD BCAD DBAC CBDA [i.e., interleaved practice]

Both have the same practice problems, but they’ve been re-arranged. If letters represented addition, subtraction, multiplication, and division, the students need to be able to choose and retrieve the appropriate strategy — vs. plug-and-chug without thinking about which strategy to use.

Temperament-Inclusive Pedagogy: Helping Introverted and Extraverted Students Thrive in a Changing Educational Landscape — from onlinelearningconsortium.org by Mary R. Fry

Excerpt (emphasis DSC):

So how do we take these different approaches to learning into account and foster a classroom environment that is more inclusive of the needs of both extraverts and introverts? Let’s first distinguish between how extraverts and introverts most prefer to learn, and then discuss ways to meet the needs of both. Extraverts tend to learn through active and social engagement with the material (group work, interactive learning experiences, performing and discussing). Verbalizing typically helps extraverts to think through their ideas and to foster new ones. They often think quickly on their feet and welcome working in large groups. It can be challenging for extraverts to generate ideas in isolation (talking through ideas is often needed) and thus working on solitary projects and writing can be challenging.

In contrast, introverts thrive with solitary/independent work and typically need this time to sort through what they are learning before they can formulate their thoughts and articulate their perspectives. Introverted learners often dislike group work (or at least the group sizes and structures that are often used in the classroom (more on this in a moment)) and find their voice drowned out in synchronous discussions as they don’t typically think as fast as their extroverted counterparts and don’t often speak until they feel they have something carefully thought out to share. Introverted learners are often quite content, and can remain attentive, through longer lectures and presentations and prefer engaging with the material in a more interactive way only after a pause or break.

From DSC:
Could/would a next-generation learning platform that has some Artificial Intelligence (AI) features baked into it — working in conjunction with a cloud-based learner profile — be of assistance here?

That is, maybe a learner could self-select the type of learning that they are: introverted or extroverted. Or perhaps they could use a sliding scaled to mix learning activities up to a certain degree. Or perhaps if one wasn’t sure of their preferences, they could ask the AI-backed system to scan for how much time they spent doing learning activities X, Y, and Z versus learning activities A, B, and C…then AI could offer up activities that meet a learner’s preferences.

(By the way, I love the idea of the “think-ink-pair-share” — to address both extroverted and introverted learners. This can be done digitally/virtually as well as in a face-to-face setting.)

All of this would further assist in helping build an enjoyment of learning. And wouldn’t that be nice? Now that we all need to learn for 40, 50, 60, 70, or even 80 years of our lives?
