New feature for the new school year.
Now, if you already have a lab assignment typed out as a PDF you can attach that PDF to a problem in ClassCube instead of retyping the instructions. Continue reading
Make it correct, clear, concise, and fast; in that order
Adding assignments in Canvas – Demo Video
Are you thinking about using ClassCube and Canvas together in your classroom? Take a look at the following video to see how easy it is to add assignments for your students.
Why Write Code on Paper?
School is about to start up for students all over the United States. And for those that are taking a computer science course for the first time, they’ll learn that it’s not always just typing code into a computer. So why do we write code on paper?
Many teachers and professors have their students write at least some of their code on paper, and then it’s hand graded rather than run through a compiler.
But why? For students this seems like a very odd thing. They’re learning to program a computer, but not using a computer.
Let’s take a step over to the other side and look at why this can be a good way to learn programming. Continue reading

Tweets on the 2017 AP CompSci Exam
If you’re not following @AP_Trevor on Twitter, you really should be. He’s the senior VP on AP and instruction at the College Board and tweets out some really great stuff about AP exams.
Right now he’s tweeting out information about exam results as they’re coming in. We’re going to look at a few of the CompSci ones since that’s what we’re about here.
Comparing output in a JUnit test
Output matching is a built in test type in ClassCube. The catch is that you may not always want to compare that the output matches exactly. Or, maybe you want to do your own comparisons.
To do this you’ll need to create your own JUnit test and use the unit testing grade type. Fortunately, it’s pretty easy to deal with output from stdOut and stdErr.
The Code
Let’s start by looking at an example JUnit test file. There’s only a shell test method called, creatively test. Take a look and then we’ll talk about the code.
