The Shift in Assessment: Why the TVET Sector Can’t Afford to Wait
AI is transforming education—but unless the TVET sector accelerates adoption, it risks falling behind in preparing learners for an increasingly AI-driven workforce.
The advent of Artificial Intelligence (AI) has sparked a transformation across various sectors, and education is no exception. With the development of Large Language Models (LLMs) like OpenAI's GPT-4, there's growing interest in leveraging AI to enhance educational processes. One area that has garnered significant attention is the potential for AI to mark students' work. But can AI truly match or surpass human educators in assessing student performance? This blog explores this question, delving into recent research, practical examples, and the ethical considerations surrounding AI-assisted marking.
Automated grading isn't new - systems like ETS’s e-rater® have been used to score essays on tests like the GRE and TOEFL1. Now, EdTech providers like sAInaptic and Graide are using AI to mark beyond multiple-choice questions. If you haven’t checked them out yet - you should!
AI marking systems typically employ Natural Language Processing (NLP) techniques to evaluate written responses. They analyse textual features such as syntax, semantics, and discourse structure. Machine learning algorithms are trained on large datasets of human-graded essays to learn scoring patterns.
A notable study titled "Can Large Language Models Make the Grade?" explored the effectiveness of LLMs in marking student work2. The research involved:
While AI shows promise in marking efficiency and consistency, it cannot replace the nuanced understanding that human teachers bring. Educators consider factors like a student's effort, creativity, and personal circumstances—elements that AI might overlook.
AI can alleviate administrative burdens, allowing teachers to focus more on instruction and student engagement. For instance, AI can handle initial grading and flagging responses that require human attention.
AI has the potential to improve both efficiency and consistency in marking. Studies like Can Large Language Models Make the Grade? show that models like GPT-4 are nearing human-level performance in specific tasks. However, there are limitations and ethical concerns that require a thoughtful, informed approach. As with other areas of AI in education, it should be seen as a tool to support—not replace—the essential role of teachers.
