Can We Trust AI-Generated Educational Content? Comparative Analysis of Human and AI-Generated Learning Resources
This addresses the need for scalable, high-quality learning materials in online education, though it is incremental as it focuses on a specific context and calls for more research.
The study tackled the problem of assessing the quality of AI-generated educational content by comparing it to student-generated resources in an introductory programming context, finding that students rated AI-generated resources as equivalent in correctness and helpfulness to peer-generated ones.
As an increasing number of students move to online learning platforms that deliver personalized learning experiences, there is a great need for the production of high-quality educational content. Large language models (LLMs) appear to offer a promising solution to the rapid creation of learning materials at scale, reducing the burden on instructors. In this study, we investigated the potential for LLMs to produce learning resources in an introductory programming context, by comparing the quality of the resources generated by an LLM with those created by students as part of a learnersourcing activity. Using a blind evaluation, students rated the correctness and helpfulness of resources generated by AI and their peers, after both were initially provided with identical exemplars. Our results show that the quality of AI-generated resources, as perceived by students, is equivalent to the quality of resources generated by their peers. This suggests that AI-generated resources may serve as viable supplementary material in certain contexts. Resources generated by LLMs tend to closely mirror the given exemplars, whereas student-generated resources exhibit greater variety in terms of content length and specific syntax features used. The study highlights the need for further research exploring different types of learning resources and a broader range of subject areas, and understanding the long-term impact of AI-generated resources on learning outcomes.
