AI Tutors and Elementary Math: Are We Expecting Too Much?
The world of education is at a crossroads. For years, educators and technologists have speculated about the potential of AI to revolutionize teaching and close the learning gap, especially in underserved areas. Bill Gates, Ethan Mollick, and others have suggested that AI-powered tutoring systems could solve the “Two Sigma Problem,” offering personalized, one-on-one learning to students everywhere. However, Apple’s new paper, GSM-Symbolic: Understanding the Limitations of Mathematical Reasoning in Large Language Models, brings a sobering reality check, particularly when it comes to using AI for math instruction.
Apple’s Findings: Why LLMs Struggle with Math
Apple’s paper highlights a key issue: even the most advanced large language models (LLMs) struggle with mathematical reasoning. The paper demonstrates that these AI systems are not capable of handling basic grade-school math problems when symbolic reasoning is required. The crux of the problem is that LLMs excel at pattern recognition and language processing, but math often requires more than that. Solving equations or reasoning through symbolic logic involves step-by-step understanding—something current models lack .
For example, LLMs might generate coherent essays or engage in back-and-forth dialogue, but when faced with tasks like manipulating numbers or symbols, their performance falters. This inconsistency is not just a small quirk; it undermines the entire premise of using AI as a universal tutor, particularly for subjects like math where accuracy is paramount.
Our two quirky AI hosts from NotebookLM do a great job discussing this topic on today's podcast:
The Two Sigma Problem: Can AI Still Be a Solution?
The Two Sigma Problem, coined by Benjamin Bloom, refers to the challenge of getting student performance up by two standard deviations—something that human tutors have consistently been able to achieve. AI-powered tutors like Khanmigo from Khan Academy and LLMs like GPT-4 have been touted as potential solutions to this problem, especially for students in underserved areas where access to quality human tutors is limited.
However, if LLMs cannot reliably handle basic math, what does this mean for their ability to serve as math tutors? While AI can help guide students through reading comprehension or writing exercises, Apple’s findings suggest that for math, at least, we’re not there yet .
The Implications for Educators
Educators who have been excited about AI-powered tutoring systems like Khanmigo may need to reconsider how and where these tools are best used. AI models can still be valuable in areas like literacy, where they can guide students through reflective thinking and comprehension. For math, however, human oversight is still critical.
Khan Academy, for instance, has acknowledged the limitations of LLMs in math and emphasized that Khanmigo’s pilot program includes strong oversight. Teachers are encouraged to monitor students and flag errors made by the AI so that it doesn’t lead to confusion. This human-AI collaboration can be effective, but without supervision, students could be led astray by AI’s mathematical mistakes .
Why LLMs Struggle with Math: A Deeper Look
The primary reason LLMs falter in math is rooted in their design. These models are trained primarily on large amounts of text data and are skilled at understanding patterns within language. Math, however, requires more than pattern recognition; it needs logical reasoning, problem-solving, and symbolic manipulation. These cognitive tasks are very different from predicting the next word in a sentence, which is what LLMs are built to do .
This gap presents a significant hurdle for those hoping that AI can serve as a universal tutor. While AI has shown promise in transforming education, particularly in areas of accessibility, its limitations in math reveal that we need to carefully balance its use with human involvement.
The Path Forward: Hybrid Learning Models
Does this mean AI can’t help at all? Absolutely not. AI still offers immense potential in education, but educators need to rethink its role. Instead of viewing AI as a replacement for human tutors, we should consider AI as a supplement. Systems like Khanmigo could be used to guide students through literacy and history while human tutors or teachers focus on math and science, areas that currently require more oversight and precision .
The goal should not be to fully automate tutoring but to create hybrid learning models where AI plays a supportive role, enhancing what human educators can do. This approach can help level the playing field for students in low-income areas, where access to human tutors is limited, but it should not come at the cost of quality, especially in subjects like math.
Final Thoughts
Apple’s new study is a timely reminder of AI’s limitations, particularly in education. While AI tutors like Khanmigo hold great promise for bridging educational gaps, especially for underserved students, their current struggles with math suggest we’re not ready to fully rely on them just yet. The solution to the Two Sigma Problem might lie in a hybrid approach, where AI and human educators work together to ensure students receive both personalized attention and accurate instruction.
