Back in July, I wrote a post enti­tled 10 Brain Tips To Teach and Learn. Those tips apply to stu­dents of any age, includ­ing adults, for ide­ally adults are still learn­ers. Why is adult learn­ing rel­e­vant in a brain-focused blog, you may wonder:

The short of it

As we age, our brain:

still forms new brain cells
can change its struc­ture & func­tion
finds pos­i­tive stress can be ben­e­fi­cial; neg­a­tive stress can be detri­men­tal
can thrive on novel chal­lenges
needs to be exer­cised, just like our bodies

The long of it

Adults may have a ten­dency to get set in their ways have been doing it this way for a long time and it works, so why change? Turns out, though, that change can be a way to keep aging brains healthy. At the April Learn­ing & the Brain con­fer­ence, the theme of which was neu­ro­plas­tic­ity, I attended sev­eral ses­sions on adult learn­ing. Here’s what the experts are saying.

CHANGE and EXERCISE

Accord­ing to Kath­leen Tay­lor & Annalee Lam­ore­aux, under­stand­ing that we have the abil­ity to change our men­tal mod­els, also known as epis­te­mo­log­i­cal change (a change in the way of know­ing), will let us open the door to trans­for­ma­tive learn­ing (being will­ing to change and hav­ing an under­stand­ing of how to change). You can down­load the slides from their pre­sen­ta­tion here.

Learn­ing some­thing new out­side our areas of expertise:

keeps us fresh, which can add a spark to our teach­ing
reminds us what it is like to be a stu­dent, which can help us empathize with our stu­dents
exer­cises our men­tal muscles

Cou­ple men­tal exer­cise with phys­i­cal exer­cise, and you can improve gen­eral cog­ni­tion and boost your cre­ativ­ity. Learn more about this from John Ratey’s book Spark: The Rev­o­lu­tion­ary New Sci­ence of Exer­cise and the Brain, which makes a com­pelling case that exer­cise is ben­e­fi­cial for cog­ni­tive health.

NEUROGENESIS

Our brains may be aging, but they are also con­tin­u­ing to develop. Neu­ro­ge­n­e­sis is the process of form­ing new brain cells, and unlike what was pre­vi­ously thought, this process con­tin­ues through­out life, as noted in this Soci­ety for Neu­ro­science brain brief on Adult Neu­ro­ge­n­e­sis.

PLASTICITY

Neu­ro­plas­tic­ity refers to the brain’s abil­ity to rewire itself. It empow­ers us to:

fix dam­aged areas of our brains (as evi­denced by the work of Edward Taub, Michael Merzenich, and Paul Bach-y-Rita, all men­tioned in Doidge’s book, ref­er­enced below)
con­tinue to learn well into old age
alter our behav­ior and per­for­mance over time

Nor­man Doidge writes exten­sively about plas­tic­ity in The Brain That Changes Itself: Sto­ries of Per­sonal Tri­umph from the Fron­tiers of Brain Sci­ence, and notes that “brain plas­tic­ity occurs in response to the envi­ron­ment, the task at hand, and our thoughts and imag­in­ings. Indeed, “in some cases, the faster you can imag­ine some­thing, the faster you can do it.

STRESS and EXERCISE

In his ses­sion on stress and neu­ro­plas­tic­ity in learn­ing, Bruce McEwen con­curred with Doidge, not­ing that “struc­tural plas­tic­ity in the adult brain is mod­u­lated by expe­ri­ence. He went on to dis­cuss the impact of stress­ful expe­ri­ences on neu­ronal activ­ity, delin­eat­ing three types of stress:

1. pos­i­tive, which con­sists of pos­i­tive challenges

2. tol­er­a­ble, which con­sists of adverse life events cou­pled with good social and emo­tional support

3. toxic, which con­sists of a sus­tained stress agent and a lack of social and emo­tional sup­port Exer­cise, in addi­tion to aid­ing cog­ni­tion, can be ben­e­fi­cial in help­ing the brain and the body man­age stress.

CHALLENGE and NOVELTY

Elkhonon Gold­berg, neu­ro­sci­en­tist and co-founder of Sharp­Brains, dis­cussing Brain Plas­tic­ity and Cog­ni­tive Fit­ness, pointed out that “as we age, our expert knowl­edge remains strong, and our capac­ity for solv­ing prob­lems within our areas of exper­tise can often exceed that of those who are younger.  He fur­ther employed us to “turn neu­ro­plas­tic­ity to your advan­tage by:

wel­com­ing novel challenges

beware of being on men­tal autopilot

remain cog­ni­tively active

Gold­berg elab­o­rates on these points in his lat­est book, The Wis­dom Para­dox: How Your Mind Can Grow Stronger As Your Brain Grows Older.

Taken in sum, all of these ideas have me imag­in­ing pro­fes­sional devel­op­ment pro­grams where teach­ers are encour­aged to explore avenues out­side of their expert areas. (More on that in a future post!) The com­bi­na­tion of being a men­tally and phys­i­cally active life­long learner isn’t just good mod­el­ing for younger brains; its also ben­e­fi­cial for us!

(Next post will con­sist of addi­tional resources on these topics.)

Lau­rie Bar­tels writes the Neu­rons Fir­ing blog to cre­ate for her­self the “the grad­u­ate course I’d love to take if it existed as a pro­gram”. She is the K-8 Com­puter Coor­di­na­tor and Tech­nol­ogy Train­ing Coor­di­na­tor at Rye Coun­try Day School in Rye, New York. She is also the orga­nizer of Dig­i­tal Wave annual sum­mer pro­fes­sional devel­op­ment, and a fre­quent attendee of Learn­ing & The Brain conferences.
