Instant Formative Feedback

Having the instant formative feedback is really useful. And that's where Codio comes in handy. They click 'check it' in Codio and it goes and tests that their code meets the specifications. It sorts correctly, it searches correctly. It has the error handling and features that we are expecting. It doesn't have memory leaks.

Auto-Grading Code

We offer two forms of automated code grading. Our standard grading is dialog driven and usually covers at least 80% of use cases. It covers argument and stdin inputs and handles multiple test cases for full code coverage. Advanced grading lets you write your own grading scripts in any language you choose. This allows you to use any 3rd party testing or support libraries and analyze any aspects of student code.

Other Auto-Graded Assessments

You can create a variety of single and multiple response MCQ (multiple response questions) assessments. We also offer fill-in-the-blank questions.

Manual Grading

Codio packs a lot of features that let you manually grade student assignments with great efficiency. You can instantly access any student's code and review, compile and execute it. Grading rubrics can be centrally defined and applied to any project. Grading moderation allows already graded assignments to be reviewed by additional faculty and these secondary grades to be used for grading quality monitoring.

Open Ended Questions

If you want to create questions that require a text or essay type answer, free text questions can be created. You can then manually grade these directly from the teacher dashboard.
