The Turnitin AI checker is an advanced tool aimed at maintaining the integrity of school work in a time when artificial intelligence (AI) tools like ChatGPT are popular. This tool helps teachers find out if a student’s work was written by an AI or a person.
As AI becomes more common in schools, figuring out whether homework is human or AI-generated is challenging. The Turnitin AI checker steps in by checking submissions to see if they’re made by AI. It works right alongside Turnitin’s existing tools, making it easy for teachers to use without having to learn how to use a new interface.
As with all other tools, the AI checker Turnitin sometimes makes mistakes, flagging a student’s own writing as AI-written. To avoid confusion, Turnitin provides reports and tips on how to understand the checker’s findings. This helps teachers make the best decisions about what’s original and what might not be.
Using the Turnitin AI checker helps teachers spot when AI tools like ChatGPT have been used to create a student’s work. Here’s a simple way to use it:
With the AI checker Turnitin, teachers can make sure student assignments are their own work, supporting genuine student effort and learning.
The AI Checker Turnitin operates by breaking down a paper into text segments, analyzing each segment against models trained to recognize AI writing.
However, this is tricky. Large language models (LLMs) like GPT-3 and GPT-3.5, which Turnitin’s tool can currently detect, are very good at mimicking human writing, so it’s hard to catch. In fact, a study showed that even linguistics experts couldn’t always tell the difference between human and AI writing, getting it right less than half the time.
Turnitin is not transparent about the exact processes and techniques behind identifying AI writing. However, writing detectors generally use natural language processing (NLP) techniques to detect whether something was created by a person or an AI.
They mainly look at two things: perplexity and burstiness.
It is about how predictable or surprising the text is. AI tools tend to make writing that’s easy to predict and smooth to read. If a piece of writing doesn’t have many surprises and is pretty smooth, the program thinks it might be AI-written because it has a low perplexity score.
But if the writing is more unpredictable, with many different word choices, it’s likely a person wrote it, showing a high perplexity score.
It looks at how sentences change in length and structure. AI-written texts tend to be very uniform, with sentences that look alike in length and structure, which means they have low burstiness.
People, on the other hand, mix things up more, using short and long sentences and different structures, leading to high burstiness.
The accuracy of Turnitin’s AI Checker is a hot topic in the education world.
In response, Turnitin conducted a study showing their AI detector doesn’t unfairly target ELLs, ensuring fairness in detecting AI-written content. Testing on diverse academic samples, including ELL writings, revealed no significant bias, with efforts ongoing to refine detection accuracy and maintain a low false positive rate.
However, when considering all the above, it is obvious that teachers cannot just rely on the tool alone – they must also review what is being flagged as AI and decide for themselves whether this is accurate or not.
Like any tool, the AI Checker Turnitin has its ups and downs. Here’s a breakdown of these:
The Turnitin AI Checker is a significant step forward in academic integrity, helping teachers tell if homework was done by students or by AI tools like ChatGPT.
While it offers benefits like supporting academic honesty and helping teachers, there are still issues to work through, such as the chance of mistakenly marking a student’s work as AI-written and worries about it being unfair to students who are learning English.
Despite these challenges, Turnitin’s commitment to continuous improvement and fairness underscores its value as a tool in the educational landscape.
Teachers are advised to use this tool wisely, using their own judgment to ensure students are genuinely doing their work while also making the most of new technology.
Yes, Turnitin can detect AI-generated content by analyzing the text against models trained to recognize patterns typical of AI writing tools like GPT-3 and GPT-3.5. However, it’s important for teachers to review flagged content personally due to the possibility of false positives.
To check your AI score on Turnitin, look at the report provided after submission. It gives a percentage indicating the likelihood of AI-generated content alongside the traditional plagiarism checker report.
Yes, ChatGPT-generated text can be detected by Turnitin’s AI checker, which is designed to identify content created by AI writing tools. It is mostly trained to detect GPT-3 and GPT-3.5 content. However, accuracy can vary – but the tool aims to reduce false positives and bias.
