Ensuring the originality of source code is critical in computer science education and programming assessments to uphold academic integrity and foster equitable evaluation. Manual code review, while thorough, presents significant challenges in terms of time, consistency, and scalability. An online code similarity checker, such as Codequiry, offers an advanced, automated solution to address these challenges. This article examines the limitations of manual code review, the benefits of computerized tools, their potential drawbacks, and how Codequiry compares to other solutions, providing educators and academic institutions with a comprehensive understanding of its value in maintaining fairness.Limitations of Manual Code ReviewManual code review involves human evaluators examining source code submissions to identify potential plagiarism. While this method allows for nuanced judgment, several constraints hinder its effectiveness in academic settings.Time-Intensive NatureManual review requires a significant time investment, particularly when evaluating numerous submissions. For instance, a course with 50 students may necessitate hours of cross-referencing to detect similarities, diverting resources from instructional responsibilities. This process becomes impractical in larger contexts, such as university courses or coding competitions.Inconsistency and Human ErrorHuman reviewers are susceptible to variability in judgment and fatigue, leading to inconsistent evaluations. Subtle similarities, such as restructured logic or renamed variables, may be overlooked, especially under time pressure. This variability undermines the fairness of assessments, as different reviewers may interpret the same code differently.Scalability ConstraintsAs the volume of submissions increases, manual review becomes increasingly unfeasible. Courses with hundreds of students or competitions with thousands of participants overwhelm reviewers, forcing compromises in thoroughness. This scalability issue risks compromising the integrity of evaluations.Advantages of an Online Code Similarity CheckerAn online code similarity checker employs sophisticated algorithms to compare code submissions, identifying similarities with efficiency and precision. Codequiry’s platform, for example, addresses the shortcomings of manual review by providing rapid, objective, and scalable analysis tailored to academic needs.Enhanced EfficiencyAutomated tools significantly reduce the time required for plagiarism detection. An AI code detector can process hundreds of submissions in minutes, comparing them against peer submissions and web-based sources, such as public repositories. This efficiency enables educators to allocate more time to teaching and providing constructive feedback.Objective and Consistent AnalysisUnlike human reviewers, automated systems deliver consistent evaluations. Codequiry utilizes abstract syntax tree (AST) analysis and tokenization to assess code structure and logic, detecting similarities despite variable names or formatting changes. For example, if two submissions implement identical algorithms with different identifiers, the platform flags the similarity with a percentage score, providing data for further investigation without immediate accusations.Scalability for Large VolumesAn online code similarity checker is designed to handle large datasets, making it suitable for courses with extensive enrollment or high-volume coding competitions. Codequiry’s cloud-based infrastructure ensures seamless processing, maintaining accuracy regardless of submission volume.Distinctive Features of Codequiry’s Code Plagiarism CheckerCodequiry’s code plagiarism checker is engineered to meet the needs of academic institutions, offering advanced functionality and integration capabilities. Below is an analysis of its key features, alongside comparisons to other tools, such as MOSS (Measure of Software Similarity).Advanced Detection TechniquesCodequiry employs AST parsing and tokenization to analyze code logic, enabling detection of similarities that evade simple text-based comparison. This approach identifies plagiarism even when code is modified through variable renaming or structural changes. In contrast, MOSS relies heavily on tokenization for pairwise comparisons but lacks robust web-source integration, limiting its ability to detect code copied from online repositories.Investigative ReportingCodequiry prioritizes investigative support over definitive judgments. Its reports include similarity scores, highlighted code segments, and references to matching sources, such as peer submissions or online repositories. This facilitates informed decision-making by educators and fosters discussions about academic integrity. MOSS provides similar pairwise comparison reports but requires manual setup and lacks the intuitive interface of Codequiry.Comprehensive Language SupportCodequiry supports languages such as Python, Java, C++, and others, accommodating diverse curricula. Its integration with learning management systems (LMS), such as Canvas, streamlines submission uploads and result reviews. MOSS supports multiple languages but operates as a standalone tool, lacking seamless LMS integration.Comparison with Other SolutionsUnlike text-focused plagiarism checkers like Turnitin, Codequiry is optimized for source code, addressing programming-specific nuances. While effective in academic settings, MOSS is less accessible to non-technical users and lacks cloud-based scalability. Other tools, such as JPlag, offer comparable functionality but may not provide the same web-source integration or user-friendly reporting level.The Role of Academic Integrity in Programming EducationMaintaining academic integrity in programming assessments ensures equitable evaluations and prepares students for professional environments.
