Automatic Code Grader for Tech Skill Courses

Key {Features}

Rich, Instant Feedback

Give learners the rich, meaningful feedback they crave, instantly displayed after completion. Students don’t just see if an answer is incorrect, they see the reasoning too.

Refresh Auto-Graded Assessments

Easily create all kinds of formative and summative auto-graded assessments with our specialized AI-powered assessment generator.

All Types of Auto-Graded Assessments

Use our code autograder for everything from single- and multiple-choice (MCQs) and fill-in-the-blank to coding assessments and Parsons problems.

Manual Grading and Rubrics

Codio enables efficient manual grading of student assignments. 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, which enables code grading quality monitoring.

In-Code Feedback

With one-click access to learner code, instructors can quickly hop into a project or assignment, give contextual feedback and guidance. They can also answer a learner's questions using in-line comment threads.

Powerful Auto-Grading for [Any Type] of Assessment

Standard Code Test

Standard code tests are dialog-driven, where you specify input data and the expected output. Codio then executes the student code, supplies the specified input data, and compares the expected output to the student code’s actual output.

Advanced Code Test

Implement unit tests, style checkers, or write custom code tests in any language that instantly grades student-written code with an advanced code test.

Multiple Choice

Easily set up multiple-choice type assessments, which provide a question and then single or multiple response options.

Fill in the Blanks

Fill in the blank questions allows for a choice between free text or offer options from a drop down. Learners can then choose the correct answer from a drop down list or complete the missing words by entering the answer.

Free Text

Give students the opportunity to answer in their own words with Free Text assessments. These assessments allow for LaTeX formatting and are recommended for math assessments. Instructors can easily review and manually grade answers.

Free Text Autograde

Similarly to Free Text, Free Text Autograde also allows students to answer in their own words. However, teachers can easily enable autograding by including a command line to execute the autograding script.

Math Assessment

Set and grade math questions for any type and level of mathematics with ease, using the Free Text assessment. Codio offers manual grading of mathematical expressions or proofs, and multiple choice assessment type to create answers.

Parsons Puzzle

Also known as a Parsons problem, Parsons Puzzles are formative assessments that ask students to arrange blocks of scrambled code, allowing them to focus on the purpose and flow of the code (often including a new pattern or feature) instead of syntax.

Rubric Based Grade Book

The Grade Book is available for rubric-based grading. The student can only see the comments, points, and rubric items once the assessment is graded and the grades are released.

Parameterized Assessments

Simply generate parameters by writing Python code on the Parameters tab, for all assessment types except Gradebook and Random.

We needed a student-facing IDE that was 'ready to go' and didn't require futzing or installation on the student's part but was sophisticated enough to handle our auto-grading demands without requiring extensive instructor time spent on dev-ops or configuration.

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.

FAQs

What Is an Automatic Grading System?

An automatic grading system is a tool that instructors use to accurately assign scores to a learner's assessment. An online code grader streamlines the grading process, removing the time-consuming and error-prone nature of manual grading.

What Are the Benefits of Automated Grading?

By leveraging sophisticated algorithms and intelligent scoring mechanisms, automatic grading systems provide consistent and objective evaluation. Automatic grading gives an unbiased assessment of a learner's performance. A code autograder can alleviate instructors' workload. It also enables them to provide prompt and detailed feedback, fostering a more engaging and effective learning experience.

What Types of Auto-Grading Does Codio Offer?

We offer two forms of online automated code grading software. Standard grading is dialog driven. It usually covers at least 80% of use cases, like stdin inputs and multiple test cases for full code coverage.

Advanced automatic grading tools enable instructors to write their own grading scripts in any language. Use any 3rd party testing or support libraries and analyze any aspects of student code.

What if I Want to Create Open-Ended Questions in Codio?

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