Computing education research (CER) is the study of how people learn computing and the invention of better ways to teach computing. This FAQ will teach you more more about the field and how you might contribute to it.

What is computing education research?

First, CER is not teaching. Teaching is helping people acquire knowledge, skills, attitudes and beliefs. Research is discovering truth and inventing solutions. Teachers teach computing, whereas computing education researchers discover what is true about the teaching and learning of computing, and invent new techniques for teaching and assessing it (some pedagogical, some computational).

It's also important to note that I construe "computing" broadly: it's not just about programming, or even just about computer science, but also about all of the phenomena surrounding computing (including privacy, security, information ethics, software engineering, etc.). This means that computing education and computing education research can and do cover far more t

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

Amazon S3 Redirect Rules Generator

A Ruby script to generate simple Amazon S3 Redirection Rules XML file.

Update: There is an app for that now! Use Amazon S3 Redirector (Web app) and you can generate the XML without any knowledge about Ruby. Thanks to @rainforestapp. BTW, It's open source too.

Gradescope Hacks

This is a collection of bookmarklets and scripts that you can use to adapt Gradescope to do (currently) unsupported things. Unless otherwise noted, make a new bookmark, then set it's link/URL to the code for each hack.

Directions

To make a new bookmarklet, create a new bookmark in your browser, then use the edit functionality to set the URL. Make sure to include the full text starting with "javascript:". When you click that bookmark while on the page it will prompt you and then do its thing. :) (Nothing should happen on any page that isn't the right one.)

Warning: These are subject to break at any time. :-)
