Projeto revolucionário e transformador. O mundo precisa de mais pessoas como Salman Khan. E quem não for Salman Khan tem que aplaudir de pé.

O cara fala uma parada muito foda. A escola do futuro vai ser mais ou menos assim: o dever de casa serão as aulas, em vídeo. E na escola os alunos farão o que hoje é o dever de casa.

Ah, e a piada em 5’10” é sensacional.

E como um sujeito desse não merece só 20 minutos, segue um vídeo mais longo de uma palestra que o Salman deu no MIT.

O que falar desse slide aqui?

Via Perestroika. E se você gostou do assunto, recomendo esse outro post assinado pelos caras da Persetroika. E essa apresentação aqui com o fodástico Sílvio Meira.

From rockets to stock markets, many of humanity’s most thrilling creations are powered by math. So why do kids lose interest in it? Conrad Wolfram says the part of math we teach — calculation by hand — isn’t just tedious, it’s mostly irrelevant to real mathematics and the real world. He presents his radical idea: teaching kids math through computer programming.

Quer ficar boquiaberto?

Como que eu nunca tinha ouvido falar nessa porra?!

Stephen Wolfram, creator of Mathematica, talks about his quest to make all knowledge computational — able to be searched, processed and manipulated. His new search engine, Wolfram Alpha, has no lesser goal than to model and explain the physics underlying the universe.

Lindo.

Designer Emily Pilloton moved to rural Bertie County, in North Carolina, to engage in a bold experiment of design-led community transformation. She’s teaching a design-build class called Studio H that engages high schoolers’ minds and bodies while bringing smart design and new opportunities to the poorest county in the state.

Foda!

O trabalho de Sugatra Mitra é do caralho. E é foda como o grande avanço não reside propriamente na tecnologia, mas sim na colaboração mútua entre as crianças.

Education scientist Sugata Mitra tackles one of the greatest problems of education — the best teachers and schools don’t exist where they’re needed most. In a series of real-life experiments from New Delhi to South Africa to Italy, he gave kids self-supervised access to the web and saw results that could revolutionize how we think about teaching.

Tem uma frase foda no fim da apresentação:

“Education is a self organising system, where learning is an emergent phenomenom”

Pra fechar, uma imagem que me impressionou:

Esse vídeo é de um distante 1988. E a resposta sobre a “desumanização” é genial.

Jobs are finished; role-playing has taken over; the job is a passe entity. The job belonged to the specialist. The kids know that they no longer live in a specialist world; you cannot have a goal today. You cannot say, ‘I’m going to start here and I’m going to work for the next three years and I’m going to go all that distance.’ Every kid knows that within three years, everything will have changed – including himself and the goal.

Adivinhe agora quem falou isso? Clay Shirky? O chefão de RH de alguma dessas empresas boçais de tão grandes? Não!! É do McLuhan!! Lá pelo meio do século passado. É, o maluco era sinistro.

Porra, Steve! Tirar o Scracth da loja de aplicativos é vacilo, porra, a idéia é do caralho!

…Apple has banned all third party software from creating ipod apps. What they did to scratch was nothing compared to what they did to Adobe. Flash CS5’s biggest feature was the ability to make flash programs for the iphone and because Apple has banned this the usefulness of flash CS5 has gone down a lot. Its a business decision. Apple wants to be in complete control of what can make apps for their machines so they ban all app creators except their own…

Para entender a estratégia da Apple, eis uma belíssima análise do Monday Note

Who, in his right mind, expects Steve Jobs to let Adobe (and other) cross-platform application development tools control his (I mean the iPhone OS) future? Cross-platform tools dangle the old “write once, run everywhere” promise. But, by being cross-platform, they don’t use, they erase “uncommon” features. To Apple, this is anathema as it wants apps developers to use, to promote its differentiation. It’s that simple. Losing differentiation is death by low margins. It’s that simple. It’s business. Apple is right to keep control of its platform’s future

Steve Jobs has seen enough in his 34 years in the computer business to know, deeply, that he doesn’t want to be at the mercy of cross-platform tools that could erase Apple’s competitive advantage. He doesn’t want to wait and beg and bitch and moan until Adobe supports the registers on Apple’s player organ. (Diplomatically or not, Jobs recently called Adobe “lazy”… But that was intra muros, in an internal all-hands company meeting.)

Does anyone mind that Jobs won’t sacrifice the truly strategic differentiation of the iPhone platform on the altar of cross-platform compatibility? Customers and critics don’t. They love the end-result. Nor do developers.

Estrategicamente não há muito o que se questionar. Mas fato é que esta medida coloca os desenvolvedores dentro de uma caixa, de uma limitação escrota. Joe Hewitt, um dos mais famosos desenvolvedores, reagiu a decisão de Steve Jobs e parou de criar aplicativos para a plataforma apple. Eis a justificativa:

My decision to stop iPhone development has had everything to do with Apple’s policies. I respect their right to manage their platform however they want, however I am philosophically opposed to the existence of their review process. I am very concerned that they are setting a horrible precedent for other software platforms, and soon gatekeepers will start infesting the lives of every software developer.

The web is still unrestricted and free, and so I am returning to my roots as a web developer. In the long term, I would like to be able to say that I helped to make the web the best mobile platform available, rather than being part of the transition to a world where every developer must go through a middleman to get their software in the hands of users.

Quem está certo? Os dois. Cada um defende o seu, mas sem dúvida nenhuma as justificativas dos desenvolvedores são muito mais nobres que as justificativas da empresa californiana. Realmente seria escroto um futuro onde os desenvolvedores teriam que passar suas criações ao crivo de grandes empresas. Se as outras empresas adotarem a mesma postura, o cenário realemente ficaria escroto.

O papo é um tanto romântico, e eu critico o romantismo que cerca a web com frequência, mas essa atitude da Apple nada mais é do que uma tentativa de sufocar a concorrência. A Apple diz se preocupar com a experiência do usuário:

“We’ve been there before, and intermediate layers between the platform and the developer ultimately produces [sic] sub-standard apps and hinders the progress of the platform.”

Eu tenho lá minhas dúvidas. E torço para que mais desenvolvedores sigam os passos de Joe. E que as empresas não adotem a mesma postura de Steve Jobs. Postura esta que mostra que a Apple consegue dar muito certo mesmo fazendo muita coisa errada.

Jamie Oliver foi ao programa do David Letterman, que ridicularizou a tentativa do chef britânico de conscientizar os americanos sobre os perigos da obesidade:

Embora eu goste do Letterman, ele foi um bom de um filho da puta nessa entrevista.

Mas ainda bem que o The Guardian fez justiça ao brilhante trabalho de Jamie Oliver nas escolas inglesas:

Today an audience of prestigious economists was told that the healthier school dinners introduced by the celebrity chef had not only significantly improved pupils’ test results, but also cut the number of days they were off sick.

Michèle Belot, of Oxford university’s Nuffield College, and Jonathan James from the University of Essex, monitored results and absences in five neighbouring local authorities – chosen for their socio-economic similarities to Greenwich — as a control. They looked at figures from 2002 to 2007 – skipping the school year 2004/5, when the new menus were introduced.

The effects seen, they said, were particularly impressive given that they emerged within a relatively short period of time, and that the campaign was not even directly targeted at improving educational outcomes.
