What is the role of CTAT in LearnLab?
CTAT is a key enabling technology within the PSLC. Tutors built with CTAT are suitable vehicles for a particular type of in vivo experiment, in which tutors are used to deliver experimental treatments. The advantages of using computer tutors for that purpose are that one can administer experimental treatments in a consistent manner (e.g., no unwanted “random” variability) and ensure detailed logging of student activities in DataShop format. CTAT can also be used by LearnLab course developers to add tutoring capability to their courses.
