Subclaims¶

q2 i? The 10 participants produced 26 tutors, of which 18 (69%) scored 4 or 5 on a 5-point quality rubric and only 1 was deficient. → Stephen B. Gilbert 2015 q2 i? Average authoring time fell from 5.1 h for Task A to 2.5 h for Task B and 1.7 h for Task C. → Stephen B. Gilbert 2015 (2)

q2 · i? · design · r2

Course-assignment study in an HCI graduate class: ten non-programmers, given a worked example and brief videos, each authored three tutors for ACM Portal search tasks, scored on a 5-point rubric. "Eighteen (69 %) received a score of either 4 or 5".

"Eighteen (69 %) received a score of either 4 or 5, indicating that the tutor went above the minimum needed to scaffold the learner through the task."

q2 · i? · design · r2

System-tracked timing in the same study, including time spent on learning materials; the quote shows declining time on task across the three successively authored tutors.

"we found that the time on task decreased as the participants moved from task to task: the average time to author Task A was 5.1 h, for Task B 2.5 h, and for Task C 1.7 h."

• 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 — 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
