- James Cantonwine, the director of research and assessment for the Peninsula school district, developed LessonLens, an AI-based coaching tool for teachers in smaller schools to provide personalized instructional feedback without the pressure of human evaluation.
- LessonLens critiques teachers’ lessons based on recordings they upload to the tool and uses predefined guidelines, such as Charlotte Danielson’s Framework for Teaching, to measure adherence to best teaching practices.
- The tool was created using “vibe coding,” a coding approach utilizing widely available AI coding applications. This made the personalized coaching tool more customized and cheaper compared to commercial options.
- Although tools created by vibe coding can be glitchier and have potential security issues, Cantonwine has worked closely with the district’s tech experts to mitigate these risks.
- The use of LessonLens is optional and not included in teachers’ performance evaluations to ensure teachers feel comfortable using it without the fear of being monitored for supervisory purposes.
- Cantonwine developed LessonLens using a non-technical coding route which helped craft a uniquely Peninsula education resource and highlighted potential areas for further improvement.
