Leveraging artificial intelligence to predict young learners’ online learning engagement

With many schools rushing to adopt Generative AI, it is important to consider the real learning gains (or lack thereof) that these tools offer. A 2023 study by Pardos & Bhandari examined the use of AI-generated hints as a scaffolding mechanism with Algebra students.
Seventy-seven participants (high school graduates selected via Amazon's MTURK system) were assigned to a control group (which provided human-generated hints) or an experimental group (which provided AI-generated hints). The researchers wanted to learn the rate of "low quality" AI-generated hints, as well as if the hints produced learning gains compared to the control group. The questions from the lesson were fed, verbatim, to ChatGPT in order to generate the hints. Quality checks were performed manually to ensure that all AI-generated hints were correct and showed the proper steps. This was then contrasted with the control group, whose hints were generated by undergraduate tutors. Pre and post tests were administered to check for learning gains between the two groups.
The results showed that 70% of the hints generated by ChatGPT were considered to be good quality, and that there was a statistically significant learning gain in the control group. A major limitation of the study is that the researchers did not prompt the AI to use any scaffolding strategies. Therefore, the quality of the hints between groups not only differed by human or AI creator, but also by pedagogical theory. Human tutors were probably more likely to employ Vygotsky-esque scaffolds, while ChatGPT was more likely to provide an immediate answer. Future work could improve upon the prompts used in this study and create a multi-tiered approach with less consequential hints being revealed at first.
