Using CEEDARs 4R process for transformation, Three classroom teachers and one Professor engaged in Lesson Study to reimagine a Mathematics Education Practicum for prospective sophomore teachers as a Providence College – Times² Academy partnership. Participants conducted rigorous research into what core research-to-practice methods would bring the most leverage and improve the student’s skill set and understanding of teaching and learning. Each teacher tested these practices, and the resultant analysis led us to a wholly revised practicum.
