Description

LearnLens is a modular LLM-based feedback and assessment system developed by Zhao et al. for curriculum-aligned science education with educator oversight.

Components

Claims

• LearnLens's modular pipeline outperforms direct-prompt baselines on scoring quality while matching latency and cost on 100 authentic student answers [+W]
• LearnLens reduces teacher feedback time, with half of teachers previously spending 10–30 minutes per assignment versus a median below 5 minutes with the system [+W]
• On the live single-node deployment, short-answer rounds take ≈32 s (≈$0.015/round) while multiple-choice rounds are ≈4× faster (≈7.6 s, ≈$0.005/round) because grading is deterministic [+W]
• Adoption intent does not differ significantly across teacher prior-practice groups, with every cohort exceeding 65% willingness to continue using LearnLens [+W]
• Teachers rate LearnLens positively across usability, relevance, and accuracy, with all nine Likert items averaging at least 4.1/5 [+W]
• System reliability and latency acted as a prerequisite bottleneck: 56.4% of started solves completed, with a 32.0-second average latency and 68.5-second p90 [~M]
