Automating Source Code Plagiarism Checks With Canvas and Codequiry

When a single CS1 assignment yields 300+ submissions, manual plagiarism checking simply doesn't scale. This hands-on guide walks through connecting Canvas to Codequiry's API, running similarity and AI-detection scans with a handful of Python scripts, and posting flagged results directly back into the SpeedGrader — so you catch the cases that matter without drowning in paperwork.

Designing Plagiarism-Resistant Programming Assignments

Copy-paste code and AI-generated solutions are flooding CS courses. Smart assignment design—parameterized prompts, incremental checkpoints, and open-ended specs—can make copying so cumbersome that students default to doing their own work. This deep dive builds a concrete, reusable playbook for instructors.

A Triage Protocol for AI-Generated Code in CS Assignments

A single run of an AI detector on a suspicious student submission is not enough. CS professors need a systematic triage protocol that stacks similarity analysis, AI code detection, web-source fingerprinting, and manual review into a defensible pipeline. This article outlines a concrete workflow you can implement this semester.

A Framework for Scanning AI-Generated Code in Student Submissions

AI large language models can now generate passable code for many introductory CS assignments, leaving instructors scrambling. A systematic scanning framework—combining AI detection, plagiarism analysis, and human review gates—can reliably identify AI-written submissions while respecting due process. Here’s how to build one.

Why Cross-Language Code Plagiarism Detection Is Now Essential

Modern CS courses often span multiple programming languages, but traditional plagiarism tools like MOSS only compare files within the same language. This case study walks through a practical detection pipeline that catches students rewriting Java logic in Python, using token-normalised AST comparisons and Codequiry’s cross-language API.

A DevOps Engineer's Playbook for Plagiarism and Code Smells in CI

This practical guide walks DevOps engineers through integrating code smell detection and plagiarism checking into a single CI pipeline. Using SonarQube and the Codequiry API, you'll learn how to catch refactoring-resistant copy-paste, known vulnerabilities, and code-quality regressions before they reach production. The guide includes a complete GitHub Actions workflow, token-based authentication, and advice on setting meaningful thresholds.

The Long Road to Refactoring-Resistant Code Plagiarism Detection

Code refactoring — renaming variables, reordering statements, extracting functions — has long been the easiest way for students to disguise copied code. This article traces the thirty-year arms race between obfuscation tactics and detection techniques, from simple string comparison to modern AST and graph-based analysis that can spot similarities even after heavy transformation. Understanding this history explains why no single method is perfect and how layered approaches like Codequiry’s hybrid engine achieve the highest accuracy.

Teaching Code Attribution Before Students Write a Single Line

Too many CS students treat code from Stack Overflow, GitHub, or AI tools as free for the taking. Teaching attribution as a core skill from the first assignment reduces plagiarism and builds professional habits. This article walks through concrete strategies, assignment patterns, and detection workflows that make attribution part of the learning process.

How Burstiness and Perplexity Catch AI-Generated Code

Burstiness and perplexity aren't just linguistic curiosities—they're the primary statistical signals that distinguish human-written source code from LLM output. This article explains exactly how these measures work under the hood, with worked examples, real-world detection rates, and honest limitations.

What 1200 Python CS1 Submissions Reveal About AI-Written Code Signatures

We analyzed 1200 introductory Python submissions from three semesters, applying perplexity, burstiness, and token-frequency analysis to separate human-written code from AI-generated samples. The results reveal a consistent set of statistical signatures that can catch GPT-generated and Copilot-assisted assignments—with measured false-positive rates at each threshold.

The Measurable Impact of Static Analysis on Student Code Quality

A semester-long controlled experiment across two sections of an introductory programming course shows that students who receive automated static analysis feedback produce measurably cleaner, more maintainable code. Cyclomatic complexity dropped 22%, test coverage rose 29%, and common code smells decreased by 38%. Here’s the methodology, the data, and what it means for code-scanning in education.
