Immersive classes, where students learn by doing

The phrase ‘hands-on learning’ often becomes a placeholder for many things. If it does not involve experiencing the subject matter, then it’s still theoretical.

There’s a school in San Diego that doing something really amazing with teaching through experience – or ‘learning by doing’ as some call it. (It is featured in ‘Creative Schools by Ken Robinson.) At High Tech High, subjects are intensely focused on real world challenges. One project, for instance on Urban Ecology is described this way.

Students will discover how humans interact with nature in urban ecosystems. They will understand the terms sustainable and efficient in order to apply them to designing improved modern cities. 

Students end up publishing an  ‘magazine’ on the Urban Ecology, talking on publishing roles.They hold staff meeting with their Editors-in-chief, who are none other than their teachers!

Is this EdTech? Is it a computer class? Can this be used to demonstrate ‘rigor’? Yes to all three! But looking at their class structure, and philosophy, it seems that this kind of pedagogy is very different. In the end it’s not about exams, but about preparing for the real world.

Blockchain fuels the sharing economy – Aaron’s article

For anyone considering dipping a toe into crypto-currency, there’s one person I’d like to point to – my son, Aaron. He’s worked with currency models from social currencies to crypto. The former is a way communities print and use their own money to sustain local industries. (One currency uses the line ‘In Farms We Trust’ as a way of thumbing its nose to the Federal alternative.)

His recent in Shareable, is titled “Blockchain as a force for good: How this technology could transform the sharing economy.” 

Blockchain is being adopted by restaurants, the energy sector, and the city of Austin, among others as he explains in the long piece. It’s definitely worth a read., even though I say so myself!

Egg-on-Facebook. Is this a confession or face-saving ploy?

Confession, or mea culpa?

Mark Zuckerberg’s published statement to Congress, tries to make it a bit of both. But that doesn’t easily get Facebook off the hook.

I find it incredulous that many of the data leaks (not hacks) were something Facebook ‘learned’ about from journalists at The Guardian, and Channel 4 etc. Or so Zuckerberg claims. How is it that a company that specializes in data harvesting and monitoring of millions of people and entities, didn’t have an algorithm or human sniffers to alert it to what was being done through its servers?

I find it odd that a company that was founded by a guy who literally ‘scraped’ data off Harvard’s computers (and thus stumbled on the business model) didn’t look out for the same thing happening to his domain.

PR Stunt or Learning Moment? When protesters take over class

Student protests happen everywhere, not only during times of turmoil. When I was in Uni, students took over parts of the campus ‘kidnapped a Dean (!) and held him for a few hours. At another time some stormed the campus police station. Most student protests happen in public spaces, with rhetoric aimed at public figures – or at least those people in power.

So what do you make of a situation when a classroom (in Reed College in Portland, Oregon) was turned into a protest space? Is the audience just students like themselves, sounding off their different perspectives? Watch this and think again.

  • Is it possible that the demonstration was set up (this doesn’t seem a spontaneous turnout) to create ‘media’ and not just to hijack the space?
  • Was the debate that took place toward the end, unintended?
  • Was it an appropriate way to address sensitive issues around a Humanities 101 class?

What’s your take?

For some background, read the piece in The Atlantic in November last year.

Cliches don’t work after this school shooting. Students will put spin doctors out of business!

I came across an observation made by Michael Shammas, who asked us to consider what we would say if Kim Jong-un disputed international arms control treaties by adapting the cliché, “Nukes don’t kill people; people kill people!”

We would dismiss it as deranged thinking, wouldn’t we?

The events following the massacre at Marjory Stoneman Douglas High School in Parkland, Florida have created a different kind of tipping point. One that shows students’ capacity to hold up these tired clichés and talking points for scrutiny. Such as these lines spoken by a senior at that school:

“They say a good guy with a gun stops a bad guy with a gun: We call BS!”

“They say guns are just tools like knives and are as dangerous as cars: We call BS!”

These students are thoughtful, logical, vocal –the kind of non-polarized citizens a country needs. Imagine what they could accomplish when they get to voting age!

Fake news – Old model recycled for digital age

Before we called it Fake News, it was called propaganda. Or just plain dirt.

The New York Times has a great story on the roots of Fake News. (I’ve always disliked the term; it suggests there is such a thing as ‘authentic news.’) When information is manipulated, and planted, and spread, it is not just fake but spurious. The Rand Corporation calls this the ‘Firehose of Falsehood‘ propaganda model.

It’s features are:

  • High-volume and multichannel
  • Rapid, continuous, and repetitive
  • Lacks commitment to objective reality
  • Lacks commitment to consistency.

The firehose brings in information from so many sources that it tends to consume and compromise the bandwidth of attention we have to process the information.

But while we pay attention to malicious actors who spread falsehoods, let’s not be blinded to other ways fake news, falsehoods and propaganda spread. In a much older analysis of news and propaganda (Manufacturing of Consent, 1998) Noam Chomsky revealed how systemic propaganda is part of the business model of newsmaking. He identified ‘filters’ in the media embed propaganda and bias.

Fake news is just a new digital iteration of what we’ve had, and blissfully ignored before. Everything old is new again!

Social media warning – This time from former Facebook exec

Didn’t you suspect the backlash was coming? Is Chamath Palihapitiya right?

The former Facebooker (someone I’ve featured before) gets to the heart of the matter. Calling out the addictive nature of social media –what he calls the “dopamine-driven feedback loops.” He doesn’t mince his words. Listen to his interview and see what you think.

A few days ago I expressed my disgust:

Indeed, we need to call out social media when it is not social, and in fact becoming thoroughly anti-social. We need to aggressively educate our younger generation before they climb on board this seductive train.

Or as Chamath says, we need a ‘hard break‘ from these tools.
