What makes Rex great?

Our built-in, patented AI tutor, Rex, helps students improve their science practices. Our research backs up this claim as we have several randomized controlled studies showing how the virtual tutor supports students and helps them transfer their learning to different science topics and domains, even after 180 days. (Li et al. 2019)!

The immediate feedback that Rex provides when students get stuck gives them the opportunity to learn and improve. Rex provides feedback on every stage of the inquiry process: during hypothesis/question formation, collecting data, data analysis, and during C-E-R! If Rex assists students in completing their investigation, the student’s score is adjusted as it shows they needed support.
