Building a Brain

When I was a new mom, I was learning about neural networks and how memory and learning work in a biomechanical sense. Did you know that every time a newborn has an experience that ‘works’ –they get milk, they get to be close to mom, they get clean, they get sleep—their brains are building synapses? Those are links between neurons that will eventually make neural pathways.

One of the fun pieces of brain development science that has been discovered is that the more you do a thing, the faster and more automatically your brain will replicate the thing. It’s not just ‘training your arm’ to throw a ball, it’s training your brain to build strong neural pathways so ‘throwing a ball’ becomes a high-speed highway of connections that make throwing a ball an act completed without confusion, thought, decisions or concentration.

For newborns, this means that if snuggling this way, and suckling this way results in a warm, fully belly, they are likely to do it again. And tomorrow, they’ll do it again and again and again. Every success strengthens the pathway. So, while the first time they tried it, it was pleasant… and a neural path was ‘walked’ through the grey matter… it’s the fifth or seventieth ‘walk’ down the same pathway that has made it visible as a track.

Initially, the synaptic ‘walk’ might be confusing and hard to retrace (poor little confused baby trying to figure out how to latch on again at 3 days old) but every single success makes the pathway stronger. Stronger pathways make for more-skilled brains…

Practice doesn’t make perfect… but it does make brains more complex.

Dated and Irrelevant Schools: Sundaes Made of Meatballs


Editor's Note: This post contains affiliate links. Linda Clement only ever shares links to books she has read and believes are of value. No authors have been harmed in the sharing of these recommendations...

A talented marketing writer, possibly named Seth...something... Rogen is probably not right... 

oh, it's Godin-- wrote a book called Meatball Sundaes, a work about marketing in the new reality of social networks, the 'long tail', and the loss of the ability of major corporations mass-marketing not-very-well-made 'necessities' to the bulge in the middle of the market. 

Essentially this was done, in 1951, by dressing up meatballs to make them look 'special' -- make a sundae with them, because chocolate sauce and whipped cream and a pretty little cherry will make them look better and then they'll not be boring old meatballs anymore...

What has this got to do with anything?

Further to the last idea (schools can --or even should-- hold back the tide of technological advancement), school systems and their conventional supporters (everyone from governments happy about the idea of installing propaganda into the majority of minors' heads, to parents happy to have someone else responsible for the poor output at 18) are locked to into the same crisis-creating past-attached disastrous thinking that got GM, Chrysler, Pontiac, Oldsmobile and Ford where they are today:

the world is changing but we are right-- our past tactics succeeded because we 
are right and the changes that have happened in the world are anomalies that we
are confident won't last, don't matter and can't affect us because we are too 
big, too right and successful because of divine right and the correct way of the 
world. This is a temporary set-back caused by a minor misalignment of unrelated 
and ultimately irrelevant stars.

Haha ha.

So... my point is that school systems operate on the cusp of

we do things the right, natural, necessary and modern way
arguing that they serve the real needs of the future adults they teach while dismissing technological and economical advances as if they don't matter at all --not to them, not to the system, not to the children, not to the adults those children will become and not to society.

Because embracing emerging technology is expensive and the schools already own all the obsolete technology, they feel secure and the simple position: we need not adapt. Now that 'knowing' is irrelevant in the face of 'finding out' and fact-gathering is the job of

webcrawlers, not people, it becomes more and more ridiculous to 'teach' facts and insist on kids--or anyone--not using the readily-available tools to answer the questions.
The 'regurgitate what I told you' form of education was poor and flawed half a century ago. Today it is not just poor and flawed, it's irrelevant.
When a system is faced with a massive advance in cheap, portable technology, readily available to the average 10 year old, it has two choices: adapt to the technology or go to war with reality. It's sad to watch a whole system engage in a fruitless war when Sun Tzu,
https://www.flickr.com/photos/zionfiction/15361058736/in/photolist-ppprAh
a thousand years ago, knew that the dumbest war to engage in is the one that cannot be won. 

No system in the history of the world has won the fight against reality. 

As my mum quips: mother nature rolls last. 

If the school system was a tyrant, it could have foreseen the troubles it would have with cell phones and stopped them becoming widely available. 

As much as the system and the people in it would like to be The Tyrant, that is not the way of the world --even if it seems, from here, that once it was.

It isn't. N
ow:
adapt or suffer
Does it seem ironic to anyone other than me that it is the most educated, the most expert on learning, who cannot conceive of a successful way to use the advances of cellphones to enhance the education, to incorporate them the way books have been, the way inexpensive paper has been, the way large numbers of same-age students have been, the way video, public address systems and even computers have been? 

It amazes me that no one in the system sees the technology as a wonder, a marvel--a boon to the potential of engaging students. Nope... it's all meatball sundaes: 
we did it right in 1951 and that right way will remain right for all time because we have this big system already in place, that's why.

Are Children Valuable People? Who is Allowed to Waste Their Time?


https://www.flickr.com/photos/wecometolearn/8066863117/in/photolist-dhQMmR-62Yv2h-8vBVYM-5EaGa6-3Wm4s-djaFxZ-pBAxjJ-pBCot6-8vBVXt-oKz53c-eF3mLA-ipytp-56sJzo-56sBsh-56or7c-56oyV6-a3Pdjy-8vBVUB-nuJMy8-aBpGDL-9MpRbq-4qNk5S-4KgiQw-9reDhr-conecb-dTW2xo-8uYX59-bHZuW6-9wYYMh-kVUSH-7WkVn6-niaHHt-8uVTqx-pk7BLi-hN1djZ-6ZDBnt-8WkzRS-du35bh-pk8JmQ-56oxxZ-rWv6dk-8vEXiu-56sCMC-3bfXUE-56owBt-56sKe9-56otwx-56sJMq-56oxii-56oqng
Way back in the olden days, I took a series of tests. In fact, I was taken out of class regularly to do a lot of tests. For months. The tests were to find out if I should skip a grade. Isn't that the coolest, aren't I amazing? I was in 4th grade. The lowest placement on the tests was grade 8 math, because I didn't have any idea what algebra was. The average placement was university, second year. Clearly, skipping a grade was going to be pointless, to say the least.

Spin forward a lot of years... until quite recently, actually. When a person is thoroughly indoctrinated into some idea by true cultural cohesiveness surrounding it, sometimes it takes a really long time to see through it. Or, rather -- gee for someone supposedly smart, it took me a long time to twig to this...

I had essentially finished high school and first year university when I was 9, except I dipped the math.

Now, here's the funny part. Or, rather the part that I've only recently stopped gritting my teeth about: 
since it was pointless to move up a year, and it's completely acceptable to waste any child's time, I got to do the next 8 years anyhow
Nope, I haven't stopped gritting my teeth about that. It still makes me really, really mad.

Now, check your response to that: a 9-year-old challenged and passed the exams to complete first year university, what should that child do tomorrow? Oh, just finish the rest of grade 4. 

Perhaps upon consideration, that's a bit silly. 

But, what, then?

Too young to go to university, obviously (is that really that obvious? Or is it just a really, really ordinary way of thinking about something we simply do not think about much?) 

Certainly can't just 'hang out' -- imagine the dangers to society, having unemployed children out wandering around after they've finished learning everything the schools hope to teach... yeah. Imagine.

Can't work (there are laws about interfering with a child's...uh... education.... um.)

It is acceptable in our society to waste a child's life any way any authority happens to see fit, and this is the perfect example: 9 years old, already done everything (except math) that will be required for the next 8 or 9 years, and, well... who cares? 

It's not as if a child has anything valuable to do with her time.
It isn't like the child's life is valued.
This is the most pervasive form of de-humanizing discrimination in our society today.

Virtually no one will speak up against boring teachers, boring or outdated coursework, poor textbooks, unnecessarily repetitive tasks, waiting around for 6 years while the rest of the class fails to catch up, or spending 13 years floundering over their heads with material they may never understand... 
Because even if it is a total waste of time, so what?
Children aren't important enough to don't have anything important to do.
Imagine a doctor, who'd passed every test and licence exam, being required to continue taking the classes that were designed to help her pass the exams, for an additional 9 years, because she wasn't 37 yet. 

What does 37 have to do with it?

Exactly. 

What does 18 have to do with it? More to the point, what on earth does being 9 have to do with it?

What Do Grades Have to Do With It?

https://www.flickr.com/photos/g-dzilla/7255907620/in/photolist-c4bqxw-gudL2-nNUMTj-6zAmW8-89TGhL-89TH5Y-CRvDSV-btULTM-88bizx-tu7EBe-pbh6Mc-RDMZSa-e66dcT-5QFQ4V-btUHWt-4MLQri-btUM7F-borSey-btULrZ-sxcS3c-nNXT6D-tcsaB1-6zAndF-c4qTjE-btULzk-ttJZGU-dLiPaC-dEus2T-btULnz-btULar-btUMjD-btUMbk-btULH4-57Kzd2-57PH5d-idxjU9-btULcx-btULpR-57YkyU-btULka-btUMet-idxbW4-btULtZ-btUMrD-idxdjp-idxEBx-btULwT-58hPb7-btUK8k-btULEH

Ah, grades... 

Remember the lovely, tight horror of seeing an entire year's effort nailed to a piece of paper in one letter or two digits? 

Now, when it's been announced, when you suddenly realize there is nothing at all you can do about it, you realize too late there was more you needed to do...

Had a conversation not too long about about the 'reality' of the fact that people will be grading you 'in the real world' for 'the rest of your life.' 

Well, someone else had that conversation at me. 

Wow, does it ever not match my personal experience. 

Even in the military, a very large organization that thinks it is forced to rate and classify, much the same way the school system does, people don't get 'graded by everyone for the rest of life.'

https://www.flickr.com/photos/wwworks/5119120679/in/photolist-9C7ADt-9ewnJY-5mZS7p-8JkgKz-7uSXSE-8SELd2-88biBa-8X8Yrf-88euwL-khqeEz-8NmQen-7Rns72-9HxFPs-7afnXW-ar5tjs-feTosg-88biBR-7VVF1c-dcsyXj-HgNHrE-6jdZCG-awXDf-835AAj-cNf2NQ-4HrMCy-9yUiFk-oTTNTD-k7GuB-ro8NU-G4aqsS-GqYN43-Gth79z-ybsMWf-GqYMNy-7CipYe-7dn7uj-68C3vL-67aTsX
From this conversation, I remembered one that I'd had years ago with a principal who actually said out loud 
'grades are objective standards.' 
We were in a group setting, and my only response was a snort of derision (because sometimes even I can be restrained).

First, a couple of facts about grades:
  1. largely arbitrary, definitely judged by individuals, each according to their own scale or their own interpretation of the 'objective' scale,
  2. like the winner of the Stanley Cup, no more a statement about this whole person and their whole knowledge of a subject than any single game is a determination of the 'best' team in the league -- even when the grade is compiled from more than a single exam,
  3. determined from the grader's understanding of the material, which certainly may be based on dated information, and the grader may simply be less knowledgeable than the person being graded (this becomes a critical problem by post-secondary, when an instructor may be the person in the room with the least experience in the field in the real world),
  4. related far more, it has been very clearly demonstrated with some very creative and devious research, to the grader's opinion of the victim than the victims' actual knowledge (everything from 'the better looking the student the better the grade' to the instructor's prior knowledge of the student-- ask any third child in the same family going to the same school about this),
  5. related to the grader's preferred learning style-- expressions that match that style are marked more highly than expressions that conflict with it, even when they're both correct,
    https://www.flickr.com/photos/audiolucistore/7359286694/in/photolist-cdjgxm-jsyKgS-5Afnxk-jBb83N-jgt7WS-5USugn-m2e6U8-dLrhCw-8MueWm-cdjjVY-746CqM-79G7PL-m2ekta-6kbNno-c8siiy-ppjXGa-5AjDYQ-hX4EBZ-5AfmRM-8EjexQ-8EjUnL-ckBvHJ-pq67uS-Mqzmw-bVWVct-m2fx3S-m2dqJp-m2f8aG-m2epye-m2dwov-m2eDMK-qK9pn-8MzrvU-m2dP2F-m2fkLU-m2f6oq-qK9Lg-qKbV8-qKbGn-m2exq6-akAzHX-8MrcQR-8DRcFn-8v1DNp-8Dife3-8MpPc4-8Mr8Ap-79G7N7-8Mubpb-8Df24g
  6. sexism is alive and well in education, and grades reflect that bias, too,
  7. based on the unsupportable idea that what is known in 'this' context (whether that be 'right now during this test' or 'expressed in this assignment' or 'how extraverted the student is and whether or not said student participates enough in class'), which generally means that students with more stable lives have better grades overall, being the least likely to have something tremendously distracting demolish the score on even one assignment or exam,
  8. based on the hiliariously impossible theory that in a random, small group of individuals it is not possible for all of them to be extremely capable.
That last one really annoys me. 

I've been in groups of more than 30 people who were all, judging by their conversation and behaviour, true idiots. But if they were all in a classroom together, some of them would receive B's on their work anyhow. Potentially, some might even win an A. 

Conversely, I've been in a classroom with 17 geniuses who all understood the material at a very high level, and some of them actually got C's. 

https://www.flickr.com/photos/53272102@N06/16597948915/in/photolist-rhGPX2-bWmtGd-566ZgL-9iofst-7Sktxj-87ubSQ-4oPsYr-6xmF4o-c2UWh9-6xhv3p-bWmukm-bWmsms-9chvEw-GUHCws-6xmJ2j-8xBdaS-f8BxSn-qmrTW6-8xybSv-8xBdjj-683hkW-96hqu8-a6zw7D-f8RU6j-bWmt2U-6xhwBD-7SkrSb-cRBnkL-8xybvn-7ShbC4-c2UWXb-bZhfGQ-6xmJjG-7Shczk-8xBde3-7Skqa3-f8S8oG-6x3p2P-f8BJcx-f8RJEm-f8Bqw8-bnDXNL-6ka41Y-f8RP2G-c2UZMC-7SksEm-7Skob1-7SkoUU-7SknJQ-6k5LKp
This is the 'statistically unlikely' idiocy that makes people who don't understand statistics attempt to force 'averages' onto very small populations. 

The fact is, if there are 10 people in a group, the chances of them scoring on a bell curve in any metric is ludicrously unlikely. 

It is much more likely that there will be clumps of identical scores. Teachers, who often know more than is good for them but less than they need to, are uncomfortable with this reality and will not give out 5 A's in a small class, even if there are no differences between those 5 students' knowledge or skills. 

Of course, this also reflects the insanity of the system that would certainly flag that many A's in one class as 'probable cheating.'

Now, having mostly been in the 'smart class' throughout school, that statistical unlikelihood became a subject of some controversy -- because the grades on the transcripts are the same. Why would a smart person (it was argued) take a 'smart' class and risk getting a B or even a C, by doing much more rigorous work, when the same student could take a 'regular' class and be virtually guaranteed all A's? 

If it's all GPA then, seriously, taking the 'dumb' class is the way to a university scholarship.

Don't you just love it when the carrot and stick methods reward completely the wrong things?

And here is my point from the beginning, in that initial conversation:

Grades are irrelevant to 'real life'.

They are also almost entirely self-referential. That is, they are made to use within the school system, and refer to things entirely within that system...

And yet grades (and GPAs) are considered by everyone in, and everyone supporting, the system as 'valuable', even when no one can articulate exactly how grades are valuable.

The troublesome logic is thus:

I know that grades are meaningless, really, but there has to be some way to rate and judge people we don't really know because there are too many of them to know... 
...and we have to communicate those ratings and judgments to the people we don't know who need to know how everyone 'scored' so they can use those ratings and judgments to ... further rate and judge these people ...instead of getting to know them.

Or, such:

Obviously grades are a poor way of rating someone's knowledge, being so easy to:

  • cheat  

  • fake

  • hire 

  • or otherwise bluster to a higher-than-justifiable mark 
...so we certainly don't know what any individual's most-accurate grade really is. 
Because we don't know how many are cheating or how many are having others do the work for them and we don't know how many (upwards or downwards) are based on instructor bias or school standing... 
...but we need some way to convey what we know about this student to others, even if we all know it's inaccurate, even if they know it's inaccurate, even if everyone knows it's inaccurate. 
We need a metric everyone already understands, so we use this deeply flawed one.
Well, now, that makes sense...
