How can we evaluate the usability of an example-tracing tutor made with CTAT.

[Daniel Sánchez Guzmán]

Hi everyone, hope you're all doing great! 

I was wondering if you could let me know whether there's any rubric or survey—either internal or published in a journal—that helps us to evaluate or identify student satisfaction levels/quality after using example-tracing tutors built with CTAT.

Thanks so much for your time and support!

Regards,

Daniel.
