LLM-Generated Tips Rival Expert-Created Tips in Helping Students Answer Quantum-Computing Questions

TL;DR

This study shows that GPT-4 can generate educational tips for quantum computing questions that are as helpful as expert-created tips, potentially easing educators' workload in large classes.

Contribution

It demonstrates that LLM-generated tips are comparable to expert tips in helping students understand quantum computing concepts.

Findings

LLM tips are more helpful and conceptually relevant than expert tips.

Participants performed better with LLM-labeled tips, indicating a placebo effect.

LLM tips can effectively replace expert tips for quantum computing education.

Abstract

Individual teaching is among the most successful ways to impart knowledge. Yet, this method is not always feasible due to large numbers of students per educator. Quantum computing serves as a prime example facing this issue, due to the hype surrounding it. Alleviating high workloads for teachers, often accompanied with individual teaching, is crucial for continuous high quality education. Therefore, leveraging Large Language Models (LLMs) such as GPT-4 to generate educational content can be valuable. We conducted two complementary studies exploring the feasibility of using GPT-4 to automatically generate tips for students. In the first one students (N=46) solved four multiple-choice quantum computing questions with either the help of expert-created or LLM-generated tips. To correct for possible biases towards LLMs, we introduced two additional conditions, making some participants believe that they were given expert-created tips, when they were given LLM-generated tips and vice versa. Our second study (N=23) aimed to directly compare the LLM-generated and expert-created tips, evaluating their quality, correctness and helpfulness, with both experienced educators and students participating. Participants in our second study found that the LLM-generated tips were significantly more helpful and pointed better towards relevant concepts than the expert-created tips, while being more prone to be giving away the answer. While participants in the first study performed significantly better in answering the quantum computing questions when given tips labeled as LLM-generated, even if they were created by an expert. This phenomenon could be a placebo effect induced by the participants' biases for LLM-generated content. Ultimately, we find that LLM-generated tips are good enough to be used instead of expert tips in the context of quantum computing basics.
