In 2009, we reported on a new Intelligent Tutoring Systems (ITS) technology, example-tracing tutors, that can be built without programming using the Cognitive Tutor Authoring Tools (CTAT). Creating example-tracing tutors was shown to be 4–8 times as cost-effective as estimates for ITS development from the literature. Since 2009, CTAT and its associated(More)
The effects of oral diethylaminoethyl-dextran (3 g total), taken 30 min before a standard mixed test meal, on plasma glucose, total cholesterol, triglycerides, total lipids, gastrin-like immunoreactivity, bombesin-like immunoreactivity, gastric-inhibitory-polypeptide-like immunoreactivity and neurotensin-like immunoreactivity were evaluated in eight healthy(More)
Intelligent tutoring systems (ITS) and MOOCs tend to have complementary pedagogical approaches, but their combination is rarely (if ever) seen. A key obstacle may be technical integration. We present a generalizable case study of extending ITS authoring technology to make tutors easily embeddable into a variety of MOOC/e-learning platforms and run on a(More)
