Perception, performance, and detectability of conversational artificial intelligence across 32 university courses

Open access

Abstract

The emergence of large language models has led to the development of powerful tools such as ChatGPT that can produce text indistinguishable from human-generated work. With the increasing accessibility of such technology, students across the globe may utilize it to help with their school work—a possibility that has sparked ample discussion on the integrity of student evaluation processes in the age of artificial intelligence (AI). To date, it is unclear how such tools perform compared to students on university-level courses across various disciplines. Further, students’ perspectives regarding the use of such tools in school work, and educators’ perspectives on treating their use as plagiarism, remain unknown. Here, we compare the performance of the state-of-the-art tool, ChatGPT, against that of students on 32 university-level courses. We also assess the degree to which its use can be detected by two classifiers designed specifically for this purpose. Additionally, we conduct a global survey across five countries, as well as a more in-depth survey at the authors’ institution, to discern students’ and educators’ perceptions of ChatGPT’s use in school work. We find that ChatGPT’s performance is comparable, if not superior, to that of students in a multitude of courses. Moreover, current AI-text classifiers cannot reliably detect ChatGPT’s use in school work, due to both their propensity to classify human-written answers as AI-generated, as well as the relative ease with which AI-generated text can be edited to evade detection. Finally, there seems to be an emerging consensus among students to use the tool, and among educators to treat its use as plagiarism. Our findings offer insights that could guide policy discussions addressing the integration of artificial intelligence into educational frameworks.

TL;DR

This paper compares ChatGPT against students across 32 university courses, surveys student and educator perceptions in five countries and at NYUAD, and tests whether AI-text classifiers can detect ChatGPT use. It finds ChatGPT often performs comparably or superior to students, current detectors are unreliable, and a simple paraphrasing attack evades detection almost entirely.

Key findings

  • ChatGPT’s performance was comparable or superior to students on nine of 32 courses in the Results (Data Structures; Introduction to Public Policy; Quantitative Synthetic Biology; Cyberwarfare; Object Oriented Programming; Structure and Properties of Civil Engineering Materials; Biopsychology; Climate/Change; Management and Organizations); the Discussion states 12 (38%) of 32. The largest gaps favoring students were for math-related and trick questions, while ChatGPT outperformed students only on factual-knowledge questions.
  • Detection was poor: OpenAI’s Text Classifier misclassified 5% of student submissions as AI-generated and 49% of ChatGPT submissions as human-generated; GPTZero had an 18% false-positive rate and 32% false-negative rate. After the Quillbot attack, false-negative rates rose from 49% to 98% for OpenAI’s classifier and from 32% to 95% for GPTZero.
  • In the global survey (N=1601 across Brazil, India, Japan, UK, US), 74% of students said they would use ChatGPT for their studies; main reasons were improving skills and saving time, while non-users mainly cited not knowing how or no need. OLS results showed students in Brazil and India were significantly more likely, and students in Japan significantly less likely, to use ChatGPT than those in the USA; prior use was associated with future use, and poor/working-class students were more likely to indicate they would use it.
  • At NYUAD, 57% of surveyed students planned to use ChatGPT for assignments and 64% expected peers to do so; 61% believed it should be used and 55% expected peers to believe so. Among professors, 69% planned to treat ChatGPT use as plagiarism and 71% expected others to do so; 72% believed it should be treated as plagiarism and 73% expected peers to believe so.

Methods

  • Course comparison: NYUAD faculty provided 10 text-based questions per course and three randomly chosen student answers per question; ChatGPT generated three distinct answers per question. Submissions were randomized and graded by three graders per course, with faculty annotating questions by Anderson and Krathwohl taxonomy dimensions and question type.
  • Surveys: a global survey recruited participants from Brazil, India, Japan, the UK, and the US, targeting at least 200 students and 100 educators per country (N=1601). A second NYUAD survey included 151 students (7.2% of 2103) and 60 professors (15.2% of 393), with OLS regression used to explore factors associated with students’ decision to use ChatGPT.
  • Detection: GPTZero and OpenAI’s AI text classifier were tested on 280 questions after excluding 40 math-only questions; 47 code-snippet questions were excluded from the Quillbot attack. Normalized confusion matrices quantified false-positive and false-negative rates before and after paraphrasing.

Limitations

  • Paper-stated: student and educator sentiments were measured in the two months after ChatGPT’s release and may evolve; large language models and detection classifiers will continue to improve, so future work should examine newer models and lower educational levels.
  • Evident from text: inter-rater reliability was below 0.6 for six of 32 courses; four were essay-based and subjective, while two were not, though excluding the two non-essay courses gave qualitatively similar results.
  • Evident from text: the survey relies on self-reports, and the NYUAD response rates were low (7.2% of students and 15.2% of professors). The text also reports nine comparable/superior courses in Results but 12 (38%) in the Discussion, an inconsistency.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
