Flexi, CK-12's AI Student Tutor Spring 2025 Study

Overview

Flexi (Student) is a student-facing AI tutoring tool designed to support independent learning, increase student motivation, and provide real-time academic support aligned to classroom content. In spring 2025, Leanlab Education partnered with Flexi to conduct a multi-method evaluation focused on understanding how students and teachers experienced the tool in real classroom settings.

Key Takeaways

Overall, the study findings indicate that Flexi’s student AI tutor was a valuable classroom tool for supporting student independence, building curiosity, and enhancing engagement with academic content. Teachers found it particularly helpful for providing students with immediate academic support, especially during independent work and review periods. Students responded positively to the opportunity to explore concepts on their own terms, though many required guidance on how to effectively prompt the AI tutor.

While Flexi (Student Tutor) was well-received, implementation challenges included variation in student readiness to use AI effectively, limitations in reading comprehension, and concerns around equity and overreliance. Survey results suggested a modest but promising shift in teachers’ attitudes toward AI, as well as perceived improvements in student academic behaviors. These early indicators, while not conclusive, point toward the AI tutor's potential to play a supportive role in student learning when implemented thoughtfully.
