Detect Plagiarism with Learner Behavior Insights

Concerns are growing now because of ChatGPT’s influence on CS education. Recent findings show Large Language Model (LLM) generated code can trick MOSS (Biderman & Raff, 2022). 
Education tools need to emphasize learner process over product.

By analyzing students' learning behaviors with a code plagiarism checker within the context of assignments or exam questions, Behavior Insights helps instructors identify and tackle plagiarism and academic dishonesty at scale. 

Out-of-the-box, Codio’s Behavior Insights comes equipped with indicators specifically configured to detect plagiarism. The intuitive dashboard displays tiles corresponding to indicators above or below predetermined thresholds.

Code Plagiarism Checker for Programming Courses

Codio's class monitoring and code plagiarism detector tools allow you to check for code copying. This will help you to detect code plagiarism and potential cases of cheating between class members. 

All of this can be done with a click of a button. Codio’s code plagiarism checker will compare the code projects of all students within a class for a specific teaching unit. You can also include other reference codes for comparison and use this as a code similarity checker. Results are available at any time and last forever, so you can run a plagiarism check and always access results.

Prevent Plagiarism & Cheating with Evergreen Curricula

Create many unique programming assessments for a large course in minutes with parameterized assessments. Or assign a bank of pre-existing assessments to students at random to individualize each student's assignments.

In just a few clicks, you can create and assign different assessments to each student.  This will individualize  their course materials and save you countless hours in course maintenance and configuration. By giving each student unique programming assessments, you can avoid plagiarism or cheating altogether. So much can be accomplished while saving countless hours reconfiguring course materials each semester.

Time Savings for All

How is Plagiarism Detected?

To check for plagiarism, the software first scans a database for similar code content. Then, it identifies its components and compares them to the content of other work. The software will then build a report that showcases any similarities between the submitted code and other source code.

According to the creators of the plagiarism detection tool MOSS, the software checks code for plagiarism in two ways. This is done through keyword analysis and by looking at groups and sequences of words. 

However, in some cases, paraphrasing is not detected because the duplicate content in the text may be different enough that it doesn’t get identified as a match. The software also scans for matches by comparing the style of writing and identifying the order of words. This creates a “fingerprint” of the document, making it easier to detect plagiarism.

This combination of methods to detect copied code is the best method to ensure original content.

Can Codio detect cheating?

Your students learn by completing original work and submitting that work for grading and feedback. Codio can help prevent plagiarism and detect cheating. To help ensure academic integrity, Codio’s platform offers the following code cheating and plagiarism checking and prevention tools. 

Behavior Insights enable teachers to see at scale whether students have copied and pasted their work from tools like ChatGPT or elsewhere. Our Plagiarism detection tool looks for similarities between student code submissions.

In addition to that, a cheating or plagiarism “scanner”—Code Playback—can help instructors understand how a student writes or produces code. This can help detect plagiarized content in order to promote and maintain academic integrity.

Playback Student Code

Code Playback is built into Codio’s integrated development environment (IDE). This feature is available to all teachers and is extremely easy to use. With a few clicks, teachers can access all of the files that students produce in Codio.

Now, when teachers want to see how a particular code file was built, they can simply select Tools  Code Playback and Codio will open the history of the in-focus code file. For a multi-file project, click on the folder icon to pull up the history of other project files too.

Prevent & Detect Plagiarism at Scale

Plagiarism detection systems available such as MOSS and JPlag were not developed for university programming courses. Therefore, they can require considerable effort to submit large files of student code projects and to interpret the results.

Codio integrates the Etector plagiarism detection system developed by CS educators for programming courses. This integration provides instructors with enough data and analysis for a lecturer to make a conclusive, final decision. The burden of project data preparation and submission to remote systems such as Moss and JPlag is removed. The result is a single-click process for the lecturer or teacher.

Keystroke Autosave-Enabled Insights

Codio automatically logs all student keystrokes, enabling advanced algorithmic exploration of learner behaviors, easy identification of skill gaps, and previously inaccessible insight into student performance and programming behaviors.

Promote Academic Integrity with a Code Plagiarism Checker

As an educator in computer science, you’re focused on students who are engaged and learning. They can only do so by understanding the material and producing code based on their conclusions. A code plagiarism checker along with Codio’s Behavior Insights tools help you to ensure your students are learning and developing new skills.
