TeachFX: Refuel helps TeachFX ship AI features in 2 weeks instead of 2 months

TeachFX, an ed-tech company focused on enhancing classroom interaction, collaborated with Refuel to integrate machine learning (ML) features into their product, enabling the detection of key educational moments in classroom sessions. This partnership allowed TeachFX to accelerate their product development, achieving over 92% agreement with expert annotators and reducing the feature development timeline from months to just two weeks. By using Refuel, TeachFX could efficiently generate high-quality training datasets for detecting specific classroom interactions such as "opportunities to respond" and "teacher feedback." The process involved ingesting anonymized classroom recordings, applying natural language instructions for data labeling, and leveraging Refuel's ability to surface low-confidence examples for refinement, ultimately allowing TeachFX to train targeted ML models effectively. This collaboration underscores the potential of large language models (LLMs) in enhancing data labeling efficiency, supporting TeachFX's mission to improve educational outcomes by providing teachers with actionable insights and feedback.
