How I Rewired My Brain to Become Fluent in Math (2014,

Sorry, education reformers, it’s still memorization and repetition we need.

There is an interesting connection between learning math and science, and learning a sport. When you learn how to swing a golf club, you perfect that swing from lots of repetition over a period of years. Your body knows what to do from a single thought—one chunk—instead of having to recall all the complex steps involved in hitting a ball.

In the same way, once you understand why you do something in math and science, you don’t have to keep re-explaining the how to yourself every time you do it. It’s not necessary to go around with 25 marbles in your pocket and lay out 5 rows of 5 marbles again and again so that you get that 5 x 5 = 25. At some point, you just know it fluently from memory. You memorize the idea that you simply add exponents—those little superscript numbers—when multiplying numbers that have the same base (104 x 105 = 109). If you use the procedure a lot, by doing many different types of problems, you will find that you understand both the why and the how behind the procedure very well indeed. The greater understanding results from the fact that your mind constructed the patterns of meaning. Continually focusing on understanding itself actually gets in the way.

As studies of chess masters, emergency room physicians, and fighter pilots have shown, in times of critical stress, conscious analysis of a situation is replaced by quick, subconscious processing as these experts rapidly draw on their deeply ingrained repertoire of neural subroutines—chunks. At some point, self-consciously “understanding” why you do what you do just slows you down and interrupts flow, resulting in worse decisions.

Understanding doesn’t build fluency; instead, fluency builds understanding. In fact, I believe that true understanding of a complex subject comes only from fluency.

At 40, Franz Kafka (1883-1924), who never married and had no children, walked through the park in Berlin when he met a girl who was crying because she had lost her favourite doll. She and Kafka searched for the doll unsuccessfully.
Kafka told her to meet him there the next day and they would come back to look for her.
The next day, when they had not yet found the doll, Kafka gave the girl a letter "written" by the doll saying "please don't cry. I took a trip to see the world. I will write to you about my adventures."
Thus began a story which continued until the end of Kafka's life.
During their meetings, Kafka read the letters of the doll carefully written with adventures and conversations that the girl found adorable.
Finally, Kafka brought back the doll (he bought one) that had returned to Berlin.
"It doesn't look like my doll at all," said the girl.
Kafka handed her another letter in which the doll wrote: "my travels have changed me." the little girl hugged the new doll and brought her happy home.
A year later Kafka died.
Many years later, the now-adult girl found a letter inside the doll. In the tiny letter signed by Kafka it was written:
"Everything you love will probably be lost, but in the end, love will return in another way."

@Alimentazione e quello che sta intorno It's also not really that important. This is not about being historically accurate, this is only about the story itself - whether true or not, it has a value in itself.
I agree, the story stands on its own. I enjoy knowing the origin of a work of art, because I often find it enriches it for me somehow. In this case, its obcure origin betwixt a possibly real anecdote from Kafka's life, Davenport's elaboration, and an Internet folk-tale adds to its sweet mystery for me.

It's poetry. Even if not true, its a beautiful invention.
The Ickabog (2020,, J.K. Rowling)

Then this lockdown happened. It’s been very hard on children, in particular, so I brought The Ickabog down from the attic, read it for the first time in years, rewrote bits of it and then read it to my children again. They told me to put back in some bits they’d liked when they were little, and here we are!

The Ickabog will be published for free on this website, in instalments, over the next seven weeks, a chapter (or two, or three), at a time. It isn’t Harry Potter and it doesn’t include magic. This is an entirely different story.

When the book is published in November, I’m going to donate all my royalties to help people who have been affected by the coronavirus. We’ll give full details later in the year.

If you can keep your head when all about you
⁠Are losing theirs and blaming it on you;
If you can trust yourself when all men doubt you,
⁠But make allowance for their doubting too:
If you can wait and not be tired by waiting,
⁠Or being lied about, don't deal in lies,
Or being hated don't give way to hating,
⁠And yet don't look too good, nor talk too wise;

If you can dream—and not make dreams your master;
⁠If you can think—and not make thoughts your aim,
If you can meet with Triumph and Disaster
⁠And treat those two impostors just the same:
If you can bear to hear the truth you've spoken
⁠Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
⁠And stoop and build 'em up with worn-out tools;

If you can make one heap of all your winnings
⁠And risk it on one turn of pitch-and-toss,
And lose, and start again at your beginnings
⁠And never breathe a word about your loss:
If you can force your heart and nerve and sinew
⁠To serve your turn long after they are gone,
And so hold on when there is nothing in you
⁠Except the Will which says to them: 'Hold on!'

If you can talk with crowds and keep your virtue,
⁠Or walk with Kings—nor lose the common touch,
If neither foes nor loving friends can hurt you,
⁠If all men count with you, but none too much:
If you can fill the unforgiving minute
⁠With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
⁠And—which is more—you'll be a Man, my son!

(Rudyard Kipling)

Great experiments done in a 3rd grade classroom

How To See Germs Spread (Coronavirus)
by Mark Rober on YouTube

El trastorno por déficit de atención con hiperactividad (TDAH) ha recibido una importante atención de investigación y es un problema que rara vez deja de ser noticia, ya sea por el tratamiento de niños con anfetaminas, por el uso excesivo o insuficiente del diagnóstico o por sus desenlaces a largo plazo.

!Children's World

La hiperactividad en la infancia es una construcción cultural. Un debate.


A pesar de toda la investigación, ha sido difícil conseguir y mantener un acuerdo profesional sobre qué es el TDAH o qué se debería hacer con él. En 2002, un grupo eminente de psiquiatras y psicólogos publicó la primera declaración de consenso sobre la ciencia, el diagnóstico y el tratamiento del TDAH (Barkley et al, 2002). Sin embargo, la declaración probablemente podría describirse mejor como la declaración de una posición porque las diversas opiniones de qué es el TDAH y sobre qué se debe hacer no fueron reflejadas ni estuvieron representadas. Fundamentales para la discusión son las preguntas sobre si el diagnóstico de TDAH representa realmente algo con sentido y qué es lo que los psiquiatras están tratando de tratar. ¿Son las diferencias en las tasas de frecuencia de TDAH en la población un reflejo de los cambios en la frecuencia de nuevos casos o reflejo del cambio en la tolerancia de la sociedad para aquellos comportamientos que no se ajustan a lo que se espera? Se lo preguntamos al Dr. Sami Timimi, psiquiatra de niños y adolescentes y autor de Psiquiatría Patológica Infantil y Medicalización de la Infancia, y al Profesor Eric Taylor, psiquiatra infantil del Instituto de Psiquiatría e investigador de la etiología, los desenlaces y el tratamiento de TDAH, para debatir sobre el planteamiento de que el TDAH se comprende mejor si se entiende como una construcción cultural.

The Magic of Chess
by Jenny Schweitzer Bell on Vimeo

Filmed at the 2019 Elementary Chess Championships at the Nashville Opryland resort, a group of children share their uninhibited, philosophical insights about the benefits of chess.
Yep. Seen that before but it's still brillant. The ending is ... kick ass smart.

Oh boy, this made my day.

(recreated and corrected a corrupted one year old post)

In our adult-centric world, children are almost never considered as interlocutors by adults. Their passive role makes them victims of environmental and institutional violence. This violence - discarding violence in extreme contexts, work, sexual, war - takes place fundamentally in the family and at school. But the city also represses them, leaving them with no space to play or move freely.

One of the most interesting non-institutional initiatives that has recently appeared is that of the Caja de Música scholarships, created and managed by Alicia Murillo from Seville and the patrons who support her. In the Sala Mera, Seville, a multidisciplinary space, boys and girls at risk of social exclusion and victims of violence, learn with the help of music: "Music does not work miracles - says Alicia Murillo - but playing music together makes them trust each other again". And they need to trust the adult world that has betrayed them again. Instead of chairs there are carpets with cushions and toys. And a courtyard without cars...

Why children become bullies at school


Bullying behaviour often emerges in childhood, and the consequences for victims can last a lifetime. What makes a child become a bully?

La era de la explotación adolescente
El capitalismo de plataforma anima a los jóvenes a venderse como marcas. Lo llama empoderamiento

La era de la explotación adolescente


Tiene que ser coña, fue nuestra primera reacción. No puede ser verdad. Parece como si viniera de una cuenta de memes surrealista, pero no, existía de verdad: Teen Boss, la jovial revista empresarial para chicas, que, hasta su último número publicado en diciembre de 2018, proporcionaba todo lo que una preadolescente influencer podría necesitar saber para: “¡CREA TU PROPIO CANAL DE YOUTUBE!”; “¡GANA DINERO RÁPIDO!”; “¡PROMOCIONA TU MARCA SIENDO TÚ MISMA!”.

¿Qué engendro corporativo infernal era el responsable de esto? Pues, en realidad, era la compañía internacional Bauer Media Group, es decir, los creadores de J-14, un tabloide para niños sobre celebridades que se fundó en 1998 y, sorprendentemente, sigue publicándose. Teen Boss era una mutación del género, un tabloide de adolescentes sobre famoseo para una cultura sádica que se rige por la aspiración de hacerse famoso, en una era en la que los códigos sociales que antes solo eran aplicables a los famosos ahora resultan válidos para todos nosotros. Reinterpretaba el estilo propagandístico de Silicon Valley en un soporte mediático antiguo y prometía que ahora tú también podías llegar a ser famosa.
