Grade Board

When students want to know the results of their tests, they do so by a public interface. A large, tiled screen is mounted to a recessed section of wall in a courtyard. The display is divided into a grid of five columns and three rows. Each cell contains one student’s results for one test, as a percentage. One cell displays an ad for military service. Another provides a reminder for the upcoming sports game. Four keyboards are situated below the screens at waist level.


To find her score, Carmen approaches one of the keyboards and enters some identifying data. In response, the column above the screen displays her score and moves the data in the other cells up. There is no way to learn of one’s test scores privately. This hits Johnny particularly hard when he checks his scores to find he has earned 35% on his Math Final, a failing grade.

Worse, his friend Carl is able to walk up to the keyboard and with a few key presses, interrupt every other student looking at the grades, and fill the entire screen with Johnny’s score for all to see, with the failing number blinking red and white, ridiculing him before his peers. After a reprimand from Johnny, Carl returns the display to normal with the press of a button.



Is ANSI the right input?

The keyboard would be a pain to keep clean, and you’d figure that a student ID would be a unique-and-memorable enough token. Does an entire ANSI keyboard need to be there? Wouldn’t a number pad be enough? But why a manual input at all? Nowadays you’d expect some near-field communication, or biometric token, which would obviate the keyboard entirely.

Are publicizing grades OK?

So there are input and interaction improvements to be made, for sure. But there’s more important issues to talk about here. Yes, students can accomplish one task with the interface well enough: Checking grades. But what about the giant, public output?

It’s fullfilling one of the dystopian goals of the fascist society in which the story takes place, which is that might makes right. Carl is a bully (even if Jonny’s friend) and in the culture of Starship Troopers, if he wants to increase Johnny’s public humiliation, why not? Johnny needs to study harder, take it on the chin, or make Carl stop. In this regard, the interface satisfies both the students’ task and the culture’s…um…values.

I originally wanted to counter that with a strong statement that, "But that’s not us." After all, modern federal privacy laws in the United States forbid this public display as a violation of students’ privacy. (See FERPA laws.) But apparently not everyone believes this. A look on (at the time of writing) shows that opinion is perfectly split on the topic. I could lay out my thoughts on which side is better for learning, but it’s really beyond the scope of this blog to build a case for either side of Lakoff’s Moral Politics.

You’re Doing More Than You Think You’re Doing

But it’s worth noting the scope of these issues at hand. This seems at first to be an interface just about checking grades, but when you look at the ecosystem in which it operates, it actually illustrates and reinforce a culture’s core virtues. The interface is sometimes not just the interface. Its designers are more than flowchart monkeys.
