Based on 5 sampled comments from this thread. Analyzed 2026-07-06.
- Praise: The effect size of 0.71-1.30 SD is exciting, hinting at significant potential for AI in education, even if the study's design has flaws.
- Praise: A system that allows LLMs to engage with students' handwritten notes could revolutionize tutoring, combining personalized interaction with reduced screen time.
- Praise: Integrating tools like a smart pen could bridge the gap between traditional learning and AI, enhancing real-time feedback for students.
- Concern: The headline result feels misleading since only 11% of students achieved full engagement, raising questions about the validity of the findings.
- Concern: Concerns about selection bias loom large; without randomized controls, the results may reflect the motivated students rather than the AI's effectiveness.
- Concern: Switching to multiple-choice questions due to student complaints undermines the credibility of the study's engagement metrics and effectiveness.
