Outline

LearnLens is a modular, LLM-based system that empowers teachers to efficiently provide effective feedback essential for student learning. Specialized in science education, it generates personalized, curriculum-aligned feedback. LearnLens consists of three components: (1) an error-aware assessment module that catches subtle reasoning errors; (2) a curriculum-based generation module that uses structured, topic-linked memory chains instead of traditional similarity-based retrieval to increase relevance and reduce noise; and (3) an educator engagement interface for customization and supervision. LearnLens addresses key challenges in existing systems, delivering scalable, high-quality feedback that empowers both teachers and students.

Takeaways, Limitations

Takeaways:
We provide personalized feedback tailored to each student's individual learning.
Increase teaching efficiency by saving teachers time providing feedback.
It is structured to align with the science curriculum, increasing relevance and providing accurate feedback.
It is a scalable system that can be applied to many students.
Limitations:
The paper content alone lacks information on specific technical limitations or performance evaluation results.
The accuracy and bias of the feedback generated due to the dependency of LLMs are subject to verification.
Further research is needed on the usability and effectiveness of educator engagement interfaces.
There is a lack of explanation of specific implementation methods or technical details.
