Description

Web xPST is a web-based authoring and delivery environment developed by Stephen B. Gilbert and colleagues for creating and deploying tutors that guide learners through tasks on third-party websites.

Components

Claims

• Students tutored by an xPST-created web statistics tutor (xSTAT) scored higher on exam transfer problems than untutored students [+M]
• Five non-programmers authoring with final Web xPST produced 74 effective statistics tutors in a month, with coding a small share of total authoring time [+M]
• Ten non-programmer graduate students quickly learned early Web xPST and produced mostly high-quality tutors, with authoring time dropping across successive tasks [+W]
• In a head-to-head comparison, xPST and CTAT both let non-programmers create high-caliber tutors, with no significant time differences by the third problem [+W]
