How to Make “Khan” Videos

Khan Academy | What software program / equipment is use…:

“Sal uses a PC with:

  • Camtasia Recorder ($200*)
  • SmoothDraw3(Free)
  • Wacom Bamboo Tablet ($80)

My students and I have been using Khan Academy videos to help us in our studies of pre-Algebra over the past fall. While there have been some kinks and bumps, the experience has been amazing from a teacher and learner point of view.

Mostly, the pause button is the most revolutionary thing to happen in education in a long while. The ability to have classroom discussions, collaborative problem solving and real in-class learning combined with independent and self-paced skills work have changed how I teach (and learn).

Over the holiday break, I’ve been making a few “Khan” style videos to go along with presentations (lectures) I’m giving on a few more complicated subjects (such as some Astronomy and celestial mechanics topics) for my 7th grade students at Carolina Day School this spring.

Someone asked about my setup, so here’s what I’m using:

I’ll post up a few when I’m done with a series but have been impressed with the Bamboo tablet and experience so far. Pretty painless and enjoyable!

Don’t Get Borked by Your Netflix Viewing

What fiscal cliff? Now we’ve got Netflix frictionless social sharing thanks to Congress!

Your Netflix rental data: coming to a Facebook timeline near you soon | Media | guardian.co.uk: “We are pleased that the Senate moved so quickly after the House,’ a Netflix spokesperson told Talking Points Memo on Wednesday. ‘We plan to introduce social features for our US members in 2013, after the president signs it.”

Interesting history of the 1988 law being amended to allow for sharing our Netflix viewings on Facebook, btw.

Robert Bork died this past week. Coincidence? Maybe. Full-circle and all that.

Yet another sign that we’re slouching towards [privacy] Gomorrah.

Learning And the Fragility of the Web

Kevin Marks has a great post connecting the notion of necessary complexity with the state of the web and our willingness to throw all of our content (pics, music, text etc) into the hands of silos and walled garden social media networks:

Epeus’ epigone: The Antifragility of the Web: “If you’ve read Nasim Taleb’s Antifragile, you know what comes next. By shielding people from the complexities of the web, by removing the fragility of links, we’re actually making things worse. We’re creating a fragility debt. Suddenly, something changes – money runs out, a pivot is declared, an aquihire happens, and the pent-up fragility is resolved in a Black Swan moment.”

The latest Instagram debacle over who owns user generated pictures points to a rising tide of web users who want more than just partial ownership of what they create simply for the sake of sharing. We’ve had another system in place for over a decade now with blogs and feeds.

Of course, it’s much easier to slap a filter on a photo and upload it to Instagram or Facebook and reap the benefits of the likes and comments received rather than uploading an image to a hosted blog and going through the necessary hoops of making sure your friends are subscribed etc.

However, this complexity begets savvy users and people who understand the fragility of the web and its main currency (the link) and why a web that is open and not centralized around one corporation is worth protecting

It’s one reason that, as a teacher, I’m big on portfolios (blogs) written and curated by each student and interlinking with other student blogs. In some small way, I hope this learning process helps young people who are setting the stage for the next iteration of the social web to appreciate what it means to have an individual name space and participate in the democracy of the commons rather than just the fiefdom of Facebook.

I’m picking up Taleb’s Antifragile tomorrow (I’m back to reading dead tree editions of books for philosophical reasons but that’s for another post).

Congress Drops Requirement to Obtain Warrant to Monitor Email

Disturbing that our notion of electronic presence is so different than our notion of physical presence (the government can’t go through your mailbox on your lawn, but going through your mailbox in a Google server is no problem) and that our law surrounding electronic communications are based on 1986 paradigms:

Congress, at Last Minute, Drops Requirement to Obtain Warrant to Monitor Email | Hacker News: Currently, the government can collect emails and other cloud data without a warrant as long as the content has been stored on a third-party server for 180 days or more. Federal agents need only demonstrate that they have “reasonable grounds to believe” the information would be useful in an investigation.

Personal Drones like Personal Computers

Personal Drone

The Drones Are Coming – Business Insider: “For example, if you’re a surfer who wants footage of yourself tearing up the waves, you would press a button on your ‘follow-me box’ and the droid would fly out to you, position itself above you, and start shooting. Once the battery gets low, the droid would detect that and land itself on the beach.”

I’m typically very optimistic about most developing technologies that have the potential to augment our lives and even improve humanity. Google Glass seems to freak out lots of people, but I think it’s a stunning and potentially revolutionary technology (especially for education and classrooms).

However, the concept of wearable computing differs greatly in my mind from the rapidly advancing tech and industries around drones. Whether for military and law enforcement uses or news and information gathering to what’s described in the above article with “personal drones,” there’s a lot to worry about from an ethical point of view.

True, every new or developing technology has its positive and negative ethical implications for greater society (or societies). However, drones are one of those technologies that I’m not sure has a positive surplus over the obvious negatives.

I have no doubts we’ll have the ability to have personal drones in the future, as much as we now have personal tracking devices we carry literally everywhere (aka smart phones). I’m sure they’ll offer many benefits not yet though of. Yet, where’s the line between helpful and dangerous?

What Google Reader Might Have Been

I miss reading my friends and people I learned from daily via RSS in (the old) Google Reader. Here’s an amazing walkthrough of what could have been…

Google’s Lost Social Network: “Pre-Twitter, it was the essential aggregation tool for news and information junkies. But Reader had also became a social network in its own right. Four years on, with Google+ ascendant, these same social functions were marked for elimination. And so, its users fretted, was their beloved Google Reader.”

Innocence lost, indeed.

But where do we go?

Fever?

Back to Field Notes

I’m insanely excited to be using Field Notes again.

I switch back and forth between Moleskines and Field Notes notebooks, but I’ve definitely missed the feel and experience of a good ad useful notebook lately since being away from Field Notes.

Sure, there are digital ways to capture todos and tasks and thoughts and notes, but ever since my time in the basement of an art gallery, I’ve realized the need for a good notebook.

Feels like an old friend is back.
