Finding meaning in video games

If we can use music videos as a shorter proxy for introducing literature responses, then what about other types of media. On The Media had an interesting interview with the Tom Bissell, the author of “Extra Lives: Why Video Games Matter“. Bissell argues that there is art worthy of criticism in video games, but there is not nearly as much as there should be.

I tend to like violent games, the same reason that I’ve worked as a war correspondent, the same reason I wrote a book about a war. I’m interested in violence.

That said, there are some games that have interesting stuff to say about violence and some games that just treat it mindlessly. And, you know both can be fun. But the ones that really affect me are the ones that actually try to address the subject. – Tom Bissell on On The Media.

In particular, he highlights “Far Cry 2”:

There’s a game called Far Cry 2 that takes place in a contemporary African civil war. It’s extremely beautiful.

And yet, it is just the most unrelentingly savage game I think I’ve ever played.

Most games that are violent give you the gun, push you in the direction of the bad guys and say hey, go kill all those guys, they’re bad. You’ll be rewarded. Good job.

Far Cry 2 does something really confounding. Going through the game, quote, “getting better at killing,” the game kind of introduces slowly that you’re actually not helping things, that, in fact, you’re kind of the problem.

Everything you’re doing is just making this conflict worse. So by the end of the game you’re just a wreck. You’re progressing through the game because that’s what the game’s asked you to do, but it’s also throwing all of this stuff back at you that’s actually shaming you a little bit for being participant in this virtual slaughter. And I love that about it. – Tom Bissell on On The Media.

Is he reading too much into violent video games trying to justify his own habits? Perhaps, but he does have a point.

When my students were telling me about Call Of Duty:Modern Warfare 2, one of the first things we talked about was the infamous airport mission. The player is an undercover agent with a terrorist organization and has to participate in shooting civilians in an attack on an airport. Jesse Stern, the scriptwriter for the video game says the mission was intended to be provocative:

People want to know. As terrifying as it is, you want to know. And there’s a part of you that wants to know what it’s like to be there because this is a human experience. These are human beings who perpetrate these acts, so you don’t really want to turn a blind eye to it. You want to take it apart and figure out how that happened and what, if anything, can be done to prevent it. Ultimately, our intention was to put you as close as possible to atrocity. As for the effect it has on you, that’s not for us to determine. Hopefully, it does have an emotional impact and it seems to have riled up a lot of people in interesting ways. Some of them good. Some of them bad.
– Jesse Stern in Gaudiosi, 2009.

There is a difference between vicariously becoming a participant in violence when a novelist lets us see the world through the eyes of a killer, and actually having to pull the virtual trigger yourself, but it seems as much one of degree as anything else. While I’ve seen some initial evidence that violent video games are bad, I’m not familiar at all with the evidence that violent novels are also bad.

Perhaps, however, when we start treating video games, particularly violent ones, in as pedantic a way as literature is sometimes treated, maybe they’ll lose some of their appeal. Or maybe, they’ll just become more educational experiences. Stern again:

When we tested the level, it was interesting. …people would get angry or sad or disgusted and immediately wonder what the Hell was going on here. And then after a few moments of having that experience, they would remember that they were in a video game and they would let go. Every single person in testing opened fire on the crowd, which is human nature. It feels so real but at the same time it’s a video game and the response to it has been fascinating. I never really knew you could elicit such a deep feeling from a video game, but it has.

Maps of wealth and population

In the coming year we’ll be looking at inequalities in wealth around the world. One way of looking at this is via the two maps above from the WORLDMAPPER website. Countries are scaled by the population, in the first image, and wealth in the second.

Worldmapper also has quite the number of very interesting maps, including maps related to health, violence, pollution, food and ecology. The species at risk map ties in well with the study of the Earth’s resources.

They also distribute some animated maps as well as free software, called ScapeToad, that you can use to make your own maps. I like the fact that their maps and software are clearly licensed and allow free educational use.

Lego Mindstorms

I’ve been curious about the Lego Mindstorms robotic systems for a while now, and I had my first chance to try them at the St. Louis Science Center.

The kits come with a micro-controller, a few motors and some sensors. While there are quite a number of ways of assembling these to make robots, the ones at the science center were pre-built except that you could just plug in a bulldozer or sweeper attachment (and a head which was purely decorative). This limited the degrees of freedom to three, which made it easier to program something useful in the hour we had with the robots.

The programming is very basic. There are two sets of instructions, one to control the movement of the robot in general, and one to control its response when the sensor detected a change in the environment. The objective of the science center’s game was to clear off a set of objects from a white rectangle within five minutes.

You could tell the robot to move forward, back or rotate while it’s on the board and to activate its sweeper or shovel. So a full program could have just five elements; general: lower shovel –> move forward –> rotate; sensor: move backward –> rotate. With these strict limitations, the programming interface is also very simple; you plug in blocks with each instruction in the series for either the general movement or the sensor reaction. With all this simplification, I’m not sure just how much the students learned about programming from our short session.

The full kit from Lego offers more freedom to design robots and thus more flexibility with the programming interface so with a little thought it could be easily integrated into the curriculum. At about $300 each the system is a bit pricy, we’d probably need to get one kit for each small group of 3-4 kids. They would probably be worth it however if we used them more than just once.

I’ve been playing with the Basic Stamp micro-controller for a while, and while it offers almost infinite flexibility, making it more useful for practical applications, it does not provide the immediate gratification of the robots, and the ease of assembly to make it the better tool for introducing robotics to middle schoolers. I still, however, tend to favor practical applications, so perhaps I can persuade a student to do an advanced project to build an automatic window for the greenhouse.

The session at the Science Center was worthwhile. All of the students seemed to enjoy it. It provided a nice integration of the mechanics and electronics we’ve been learning about all year, and a glimpse of where technology is taking us in the future.

Captured by PowerPoint

“PowerPoint makes us stupid” – Gen. James N. Mattis

When we create presentations we combine multiple sources of information and reinterpret them in new ways. Presenting demonstrates more sophisticated learning. Yet as we we organize and categorize we fit the reinterpreted information into models and these models themselves impose their own logic. Models are defined by their own rigidity of organization and thinking that can straightjacket both the viewer and the creator of the presentation.

PowerPoint is a ubiquitous and powerful tool. Most of students favor it for their presentations. However, PowerPoint’s model requires breaking things down into bulleted lists, a hierarchical array of topics and subtopics. It makes it harder to show interconnections.

The U.S. military is becoming worried that their extensive use of PowerPoint is making their job harder.

“It’s dangerous because it can create the illusion of understanding and the illusion of control,” General McMaster said in a telephone interview afterward. “Some problems in the world are not bullet-izable.” – Bumiller (2010)

Elizabeth Bumiller has an excellent article in the New York Times about the effect of PowerPoint on the military titled, “We Have Met the Enemy and He Is PowerPoint“. It’s a great reminder of why students need to practice a variety of different presentation techniques.

slides impart less information than a five-page paper can hold, and that they relieve the briefer of the need to polish writing to convey an analytic, persuasive point. – Bumiller (2010)

Co-opting the iPod: Flashcards

Flashcard Touch for the iPod Touch

iPod Touches are quite convenient little PDA’s. Beautifully tactile, they are a pleasure to use. A few of my students have them and I’ve had to think long and hard about allowing iPods in the classroom because, for a little while there, students were using them under the table for all sorts of illicit applications (games). I was tempted to ban them outright, and I have not yet made a final decision but I thought I’d try co-opting the devices first.

So I now have a few students using the iPod Calendar, taking notes, and now one has found a nice little flashcard app called Cramberry. Apparently, the major selling point was its catch-phrase, “Studying doesn’t have to be painful.” The app costs $4.99 for the full version (the Lite version is useless). I’ve also tested Flashcard Touch myself, which is free this month (March), and it seems to work well (see the screen capture).

PDA’s are still on probation; they can be very useful. The outstanding question is one of trust. Will students use them appropriately, or are they too much of a temptation. A key Montessori principle is that students should take responsibility for their learning and trust is an essential component. I am cautiously optimistic.

Math map

When introducing the x,y coordinate system using a world map it is most effective if you use the right type of map projection. Most maps use a Mercator projection which stretches thing out as you get closer to the poles. You can see this in how the latitude lines get further apart as you get closer to higher latitudes and Antarctica and Greenland get all stretched out.

The Mercator map is great for navigation, because if you measure angles on the map (bearings) between two places, you get the right bearing to sail your ship.

The better map to use for demonstrating the coordinate system would have an equirectangular projection, where all of the lines of latitude and longitude are equally spaced. These are harder to find, so I’m posting here a background map with the latitude and longitude marked on it (in 10 degree increments).

Notice the difference in sizes between the maps and the size of Greenland.

I’m also posting here, because it might be useful, a simple linear graph in Excel (or for OpenOffice) that simply plots lines if you enter the equation in slope-intercept form. There are lots of websites that let you do some really cool things (I’ll post about them later), but sometimes the simplest is what you want.

Mind-Mapping software (Free)

VUE mindmap

I recently received a tip about the VUE mind-mapping software. It’s free from Tufts University and it’s open source, though you do have to register to download the software. A quick test that produced the image above shows that it’s pretty easy to use and can easily incorporate images.

Free software. It’s better than coupons.
