Plain-Language Brief

Researchers introduce Int-Bench, a benchmark to evaluate AI language models (LLMs) as tutors or thought partners during problem-solving. The study reveals that LLMs intervene more frequently and earlier than humans, providing complete solutions rather than targeted hints, suggesting they prioritize short-term success over fostering deep learning and long-term success.

What the Document Says

  • The research focuses on Large Language Models (LLMs) as tutors or thought partners.
  • It discusses the impact of AI assistance during problem-solving, with a focus on intervention decisions by AI systems.
  • Int-Bench is introduced as a simulation-based benchmark for evaluating LLM interventions during learning.
  • The study evaluates LLMs across three domains: code debugging, mathematics, and brain teasers.
  • Findings reveal that LLMs intervene more frequently and earlier than humans.
  • It is noted that LLMs tend to provide complete solutions instead of targeted hints.
  • The research suggests that current LLM assistants prioritize short-term success over supporting reasoning processes needed for deep learning and long-term success.

May include interpretation. Labeled where it does.

The study focuses on Large Language Models (LLMs) as tutors or thought partners, evaluating their intervention styles and comparing them to humans. The research suggests that current LLM assistants often optimize for short-term success rather than supporting the reasoning processes needed for deeper learning and long-term success.

Raw Abstract / Excerpt

Large language models (LLMs) are increasingly used as tutors and thought partners, helping users reason through problems. While guidance from AI assistants can scaffold thinking and foster learning, such benefits depend on how they help--for instance, intervening too early or too frequently may hinder true learning and cognitive engagement. Yet how AI systems navigate intervention decisions during problem-solving remains poorly understood. Here, we introduce Int-Bench, a simulation-based benchmark for evaluating LLM interventions during learning. Int-Bench simulates a 'student' solving a problem while a 'teacher' monitors the student's reasoning and decides whether, when, and how to intervene. Across three domains--code debugging, mathematics, and brain teasers--we evaluate LLM teachers on the frequency and timing of interventions, as well as their impact on both immediate task success and generalization to new problems. We also compare LLMs to humans, finding that LLMs intervene more frequently and earlier than humans. Moreover, in contrast to humans, they tend to provide complete solutions rather than targeted hints. These findings suggest that current LLM assistants often optimize for short-term success rather than supporting the reasoning processes needed for deeper learning and long-term success.
