Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? In over 50 percent of completed eSpark quests students needed all three post-quiz attempts, and among three-attempt quests students scored 80 percent or more only 14 percent of the time, being promoted after making a video instead. → Gadgil 2016

q2 · i? · design · r2
Analysis of eSpark log data on 2078 completed quests from September 10 to May 6. The report found "students scored a mastery level of 80 percent or more only 14 percent of the times" on three-attempt quests; the rest were promoted after making a video.
"Furthermore, of those quests in which students needed three attempts on the post-test, students scored a mastery level of 80 percent or more only 14 percent of the times (See Figure 4)."
Discussion¶
Related Claims¶
- Mastery learning implementation did not reduce material covered or instructional pace, contradicting the Robin Hood contention — the general claim this finding bears on, with the studies behind it
- Using the ePSRL Management System shows no significant difference in mean assessment results or mean attempts per quiz between users and non-users — related
- In CPS ninth-grade math sections using mastery-based or weekly grading, those categories determined nearly all of the final grade; otherwise assessments carried the highest weight, with a median of 60 percent exceeding the CPS/CTU 50 percent recommendation — related
- Retrieval Failure Reduces Benefit — related
- Learning paths used for SRL improved accuracy and performance without increasing effort, and tutoring-system benefits required sustained practice — related
- Effects of instructions on some measures were inconsistent across experiments, and instructed students did not recall all items to criterion — related
- Socratic participants required nearly twice as many attempts to reach the 80% mastery threshold as Full participants (d = -2.01), and 58% of the exercises of Socratic participants who abandoned the dialogue mid-way never reached the threshold — related
