q2 · i? · design · r2

Case study of five authors (two instructors, three undergraduates) building a college statistics tutor using JotForm and Web xPST. The quote separates total time from "7.37 h editing the xPST Instruction File".

"Authors averaged 28.57 h logged on to the system across the month for the total time (with a range of 18.45 to 36.85 h), and a mean of 7.37 h editing the xPST Instruction File (a range of 4.87 to 9.48 h)."

Quality assessment of all 74 problems authored in the same month-long case study, scored with the Table 2 rubric; the quote states all models met the minimum for tutoring.

"All 74 of the models were deemed to meet the minimum needed in order to provide tutoring"

Related Claims¶

• Ten non-programmer graduate students quickly learned early Web xPST and produced mostly high-quality tutors, with authoring time dropping across successive tasks — related
• 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 — related
• Students tutored by an xPST-created web statistics tutor (xSTAT) scored higher on exam transfer problems than untutored students — related
