From Light

I haven’t posted in a while, in part because I’ve been busy with a lot of things. Maybe I’ll make posts about some of those other things at one point, but right now I just want to talk about From Light.

Logo for the game.

From Light is a game that I have had the pleasure and honor to help develop. It was originally created as a class project by two other students, but when it showed promise they decided to develop it further. Our team has now grown to 10 people, all (save one) students at USC.

The game is a 2D puzzle platformer based on long-exposure photography (holy hell have I said that line a lot). Basically, you can etch out light trails onto film using the stars in the sky, then jump on those trails to navigate the levels.

I mention that I’ve said the above line a lot because the game got accepted into the PAX 10 for PAX 2015, and I went up to Seattle last weekend with 3 other teammates to show the game off at the four-day gaming convention. This, you may have gathered, is completely and mindbogglingly awesome. I get to work on a game that is recognized and validated by real-world people! And truly, the reception of PAX was way more than I ever would have expected. People frickin’ loved the game!

And at PAX one of the things I heard again and again was that taking a game to completion, to the point where it could be shipped and sold as an actual game (y’know, for money), is an invaluable experience. Not only do you get a sellable game and a fantastic line on your resume, you also get all the experience involved in taking a game from 80% to 100%, and all the non-development business stuff involved in getting your game out to consumers. Needless to say, this convinced me that we should take From Light to completion. Before, I had been hesitant because as students it was unlikely we could put in the time to finish it fully. However, I am now willing to work harder than I have ever worked before to finish this game.

In the meantime, if it strikes your fancy please “like” the game on Facebook, or follow us on Twitter, or just download the game from our website.

Using Games to Educate

In the last few years we’ve seen the Internet playing a larger and larger role in education. Everyone seems to expect a revolution in education within 20 years. It’s possible, although I don’t think it will come from the direction that everyone thinks it will (see my post on online education). I want to give my two cents about an ancillary approach: videogames. Games don’t have to teach the students anything. In fact, I think they are much more useful as vehicles for the education. Games provide a background, a context, for new knowledge. For example, playing Deus Ex: Human Revolution (play chapters of a game as homework instead of reading chapters of a book?) could help spark discussion about the current situation of computers, implants, artificial intelligence, politics, etc. The experiences within the game outside of the lesson help students stay interested and apply the knowledge, even if subconsciously, beyond the classroom.

I’m going to focus on two games: Kerbal Space Program and Minecraft. Prmrytchr has a whole blog on using Minecraft (as well as other games) in the classroom, so I’m going to focus on the technical aspects.

the KSP splash

Kerbal Space Program (KSP) is an indie game currently under development with an open alpha available for purchase. In the game, you run the space agency of a particularly derpy alien race in their Sol-like system. In sandbox mode, you can throw together rockets, probes, rovers, space stations, planes, and planetary bases from a wide assortment of parts. Then you launch your constructions and control them to the best of your abilities.

While hard to grasp at first, the game is incredibly fun. You do need a rudimentary understanding of kinematics to play well. This is the first step in its ability to act as an educational tool. While you can strap an engine onto a fuel tank and try to fly it, you quickly realize that doing anything impressive — such as putting an object in orbit — requires a bit of education. While you could watch tutorials, you could also get a lesson about basic kinematics and orbital mechanics from a present teacher. There’s an opportunity for lessons on engineering, as well.

As students become more proficient, more complex opportunities open up to them. Orbital rendezvous and gravitational slingshots get more involved physically. Spacecraft design, between mass conservation, fuel-mass ratio, reaction thruster placement, and properties of engines, is a great opportunity for springboarding into other physics. Other elements of spacecraft design that aren’t simulated in KSP, such as heat management, enter the realm of thermodynamics. Ancillary topics that arise when discussing space exploration can involve relativity and electromagnetic waves.

Minecraft, on the other hand, is about as physically unrealistic as you can get. However, it provides an awesome way to teach logic and economics. Even vanilla Minecraft has a growing arsenal of parts which allow rudimentary (or not so rudimentary) automation. Redstone is a powerful tool for doing any sort of logical manipulation — or teaching it. Watching your toolbox of gates and mechanisms grow out of a few basic ground rules is amazing. Creative minds are pushed to imagining new ways of using redstone, pistons, minecarts, and all the other machines being added in. While I’m not a fan, mods like Technic or Tekkit expand the array of basic parts at your disposal.

Multiplayer in Minecraft is an interesting case study of economic theory. Because the system varies so much from the real world, it provides an outside perspective on traditional economic theory. As you teach the basics of microeconomics, you can analyze why Minecraft’s multiplayer economy and identify how to restrict it. The ultimate goal of the class could be to establish a working economic system on a Minecraft server (perhaps through plugins/mods?).

Whether or not any of these are good ideas, it illuminates how games don’t have to be the primary vehicle of learning to be a useful educational tool. Games can merely be a springboard, a point of reference from which lessons emerge. The game keeps the students interested and grounded in the topic, while providing a useful outlet and vector of fortification for the knowledge they are getting in class.

A Forum for Original Thought

Nowadays, people hunger for original analyses and theses. Their pangs are reflected in the popularity of video series like The Idea Channel, Extra Credits, The Big Picture, and TED talks. Essentially, these are just spoken essays and presentations. They don’t really utilize the video medium, other than by coupling speech with a slideshow of images and (occasionally) video clips. Yet more and more these videos are supplementing written forms like blogs and columns. The intersection of unquenchable desire for consumable media (i.e. videos) and a veritable drought of mental stimulation makes spoken essays a desirable form of idea transmission.

Perhaps the number of quick-fact “educational” videos (e.g. Minute Physics, Smarter Every Day, CGPgrey, Vsauce, numberphile) stimulated the Internet’s interest in science. Indeed, there seems to be a vibe coursing through the tubes that “science is cool”, even if the way science is taught in schools isn’t. The realization that the scientific realm, learning, and, more generally, intelligent thought can be interesting has made people desire an influx of original analysis. It stimulates the brain, giving way to more thought in a way that other media has (mostly) failed to do.

In a world with an endless volume of consumable content, our brains may have become starved. Long periods of rumination can be painful and boring, so we flood it with cheap, throwaway media. Yet these times of inward reflection may serve an important purpose. Unfortunately, our over-stimulation by Internet videos, TV, movies, video games, and music has left us unable to focus on content-delivery platforms like text. We thirst for mental stimulation, yet cannot bear to gain it by taking a step backwards. This conundrum gave rise to the popularity of “spoken essays”. They inject creative, original thought quickly and painlessly. As we mull over this gem, we can further explore the subject in the video comments. Such discussion is evidenced by the considerable quality of comments on the aforementioned videos. Trolls, raging arguments over politics and religion, and insults have given way to (somewhat) thoughtful debates about the video’s analysis. Occasionally the next video in the series might make mention of some interesting points or surprising overall consensus concerning the previous video.

But is the classroom going extinct as a forum for intelligent discussion? Does it have a place in the furious online world? Perhaps. Although quick-fact videos give information, they very rarely delve into the depths of the subject and explain it in a way that lets the viewer solve entirely new problems on their own. They give the information top-soil, but hold back any sort of theoretical bedrock. A viewer might come out feeling smarter, but she will not have gained any tools in her arsenal of critical analysis and problem solving. This is partially due to the medium. Spending a longer amount of time to explore the subject drives off the initial appeal of the videos: quick learning.

However, some video series manage to seriously teach a subject while staying interesting. Crash Course has series on biology, literature, ecology, US history, and world history, served up by the eponymous vlogbrothers. They don’t necessarily go into the same depth that a yearlong course would, but that’s not really a problem here (it’s called “Crash Course” for a reason). The fact that dozens of videos are being spent exploring one subject is a start. Another faux-classroom video venue is Udacity. Udacity is a different beast; it is much more of an exploration into online courses than Crash Course. The physical classroom is woefully unfit to teach computer science. Udacity takes a stab at creating a classroom environment that takes advantage of its medium to deliver a more fitting CS education to a much greater volume of people, while still keeping a basic academic form.

Ultimately, I see a rise in the popularity of systems like Udacity, as well as series like Extra Credits and The Idea Channel. If educators want to truly grab the interest of new generations, they need to examine that which is already capturing attention. Rather than lamenting the advent of consumable, throwaway media, embrace it. There is a place for education in online videos and video games.
