Higher Education and the Coming Internet Autodidact

There is a growing movement of people who are learning on their own, rather than relying on institutions of higher learning to provide the necessary structure and opportunity. The Internet has begun to provide access to information with ease and rapidity never before seen in human history. As a result, people who are interested in learning are able to do so without having to rely on the traditional gatekeepers of knowledge.

Evidence of this change is easy to find: The Khan Academy, Make Magazine, Instructables.com, and a whole wealth of podcasts and blogs on nearly any subject imaginable. The experts might still live in an ivory tower, but when that tower has broadband, the rest of us no longer have to make the pilgrimage to the tower to benefit from their expertise. And increasingly, experts seem to find those towers drafty and uncomfortable homes, and choose to be other places altogether.

Some schools have begun to embrace that change in various ways. Several members of my team at work have recently learned Objective C programming to create iPhone applications. Since Texas State University doesn’t offer any classes of the sort currently, many of us have worked our way through the iPhone development course at Stanford University — not by actually attending, but by taking advantage of the videos of the lectures and the supporting documentation that Stanford has published free of charge online.

While this sort of information broadcast is terrific, there is concern in academe, expressed at a recent Higher Education Leadership Conference, that this isn’t going far enough to address the changes that are coming, that in fact students are increasingly able to educate themselves, and will only rely on the University to accredit their learning, leaving Universities a husk of their former selves.

I think that change is indeed coming, and as someone who has a terrible time sitting patiently through classes just to learn the stuff I want to, I welcome it. However, I also suspect that the situation is not quite as dire for our institutions of higher learning as it’s painted. I know there are lots of people who benefit a great deal from having the clear structure and discipline that courses provide. And while the way of the self-taught is one that Universities haven’t embraced sufficiently up until now, giving them some long-overdue attention and validation doesn’t mean that the traditional student will vanish.

Different people have different learning styles, and educational institutions have to learn to grow to embrace them all, rather than flopping wholesale from one approach to another. Their future may just depend on it.

Tonight’s Excitement

The series of events:

  1. We offer to look after our neighbor’s dog while she’s away.
  2. Our neighbor deposits her keys with us and leaves town.
  3. Liam’s friend Noah comes over to spend the night with us.
  4. We go have spaghetti dinner with friends down the street.
  5. Liam, Noah, Maggie and I return to the house so that they can get chores done.
  6. While I’m sitting in the bedroom, Liam says “Dad! Come quick! Noah can’t breathe!”
  7. I run into the living room. My throat immediately starts burning.
  8. We rush everyone outside.
  9. Liam was worries about Noah, Maggie, and the cats, who are sitting in the front window looking at us.
  10. I hold my breath, go back in and grab the cats. We toss them in the tent we already have set up in the front yard.
  11. Kathy, Abigail, and Abby’s friend Ethan arrive. Kathy and Ethan go in for a moment and quickly get driven back out of the house by the chemical burning.
  12. We call 911, explain the situation, and have a fire truck and ambulance parked outside in about 3 minutes.
  13. After hearing about the situation, the firemen suit up and go inside while the paramedics talk to all of the kids and take their vitals.
  14. The remaining firemen quizz us about cleansers, chemicals, or anything else that might have been spilled. We can’t think of anything.
  15. One of the firemen asks whether we had pepper spray or mace. We answer “No” at first, but then remember that our neighbor’s keychain has some sort of black cylinder attached.
  16. Kathy asks the boys whether they had touched the keys. They assure her they hadn’t. Then she calls Maggie (who has gone over to the neighbor’s house) and asks her. She told Kathy that she had squirted out some of the contents, but had no idea what it was. Mystery solved!
  17. The EMS and firefighters wrap up. We sheepishly thank them and wave them on their way.
  18. Noah’s mom shows up to retrieve him.
  19. As Kathy is explaining the situation to Noah’s mom, she squirts the pepper spray again to demonstrate what happened, upwind from everyone, setting off another round of coughing, irritated throats, and amused recriminations.
  20. Our coughing ends. We repatriate the cats. All is back to normal at last.

Weekend Photography Project: Build a Light Box

I have family and friends who are terrific at making some really cool stuff. And while much of it looks great in situ, sometimes I want to take a photo that shows something off all by itself, with no background to distract the viewer from the subject of the photo. You know, like this:

Key

To do this sort of photography, you need something called a light box. The key ingredients of a light box are a seamless background and bright, diffuse lighting. You can, of course, buy a commercial one for $100. But with a quick trip to the hardware store, you can build one yourself very cheaply.

Here’s what you’ll need to build this project:

  • 1 10′ 3/4″ length of PVC pipe
  • 4 90° 3/4″ PVC elbow socket fittings
  • 4 Tee 3/4″ Tee elbow socket fittings
  • 1 white posterboard
  • 1 white sheet
  • 1 lamp with daylight bulb
  • tape

Once you’ve got these pieces, start by cutting the 10′ PVC pipe into the following lengths:

  • 6 11″ lengths
  • 4 2″ lengths
  • 2 21″ lengths

Once you’ve cut the pipe to the above lengths, piece together one of the long sides by fitting together the following pieces in order: an 11″ segment, a 90° elbow socket, a 2″ segment, a tee socket, a 21″ segment, a tee socket, a 2″ segment, a 90° elbow socket, and an 11″ segment. Rotate all the bits to look something like this (click for more detail):

Side 1

Friction should be enough to hold the parts together — you shouldn’t need to use any PVC cement. Once you’ve done one of these, do another exactly like it.

Now that you’ve got the two sides built, take the remaining 11″ segments and fit them into the openings on the Tee sockets, like so:

Side and Top

Finally, take the other side and fit its Tee sockets to the 11″ segments you’ve just added to side 1. Flip the box onto its feet, and you should have the frame for your lightbox, ready to go:

Frame Assembled

Now that your superstructure is complete, use the tape to secure the short edge of your posterboard to one of the long 21″ segments along the top of the frame. Allow the posterboard to hang down and to bend naturally, providing a flat surface and a background with a smooth transition between the two:

Posterboard from Front

Posterboard from Side

Now that you have the frame and background in place, simply drape the sheet over the frame. When it is between your subject and your light source, the sheet will act as a light diffuser.

Sheet in Place

Now that you’ve got all the parts in place, put your subject on the flat part of the posterboard, grab your lamp in one hand, your camera in the other, pull the front of the sheet down, and start taking some pictures!

Taking a picture

Some things to try:

  1. Move your light source around. While the sheet helps diffuse the light, the general angle from which it’s coming can still make a fair bit of difference in how your subject looks.
  2. Experiment with light colors. I suggested a daylight (5500K color temperature) bulb to start with, as it will keep you from having to mess with your color balance too much, but it’s possible to get interesting effects with other colors as well.
  3. Try multiple lamps. Having more than one light source can make the lighting even more diffuse, or if you use lights with different colors, can bring out the angles of your subject more obviously.
  4. Take off the white posterboard and try black or another color.
  5. Use a light source with a reflector, like a work light or floodlight. This will help your lighting be both brighter and a bit more diffuse.

If you decide to dive into this project and have any questions, drop me an email and I’ll do my best to help out. Have fun!

UPDATE: A note from my friend Jonathan Ireland, who is a far more accomplished photographer than I am: “Re: , if you are aiming to achieve neutral, and your camera supports manual whitepoint adjustment, simply read the lit white background first to set the whitepoint. use the dull side of the posterboard for less glare.”

UPDATE 2: You can also see some more photos taken with this light box rig in my album Liam’s Shop of Horrors.

Mojo

All of you folks who are as interested in location-based gaming as I am have been checking in on Gowalla, Foursquare, SCVNGR, Facebook, Rally Up, or Yelp for a while now. But the lame thing about those services is that you actually have to go somewhere and do something to earn points! Enter Mojo, the web-location based game for folks who are shackled to their desks all through the day but still want the spurious sense of accomplishment that these games bring!

Teasing aside, it’s an interesting concept: allowing people to check-in on various websites and engage with the content there in various ways to earn credit. I’ve added it to the site here; feel free to play around with it if you’d like to see how it works. Just click that little “Earn Mojo” tab on the right to get started. (Though given how infrequently I get around to posting, if any of you earn the “365 Days in a Row” achievement, I’ll be forced to come over there and cut off your internet privileges. Don’t think I won’t.)
