Subclaims¶
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? DBN posterior mastery probabilities were highest for wind direction (0.69) and air movement (0.64), while precipitation type and wind speed showed extremely low mastery probabilities for most time slices. → Ying Cui 2019

q2 · i? · design · r2
DBN analysis in GeNIe of students' first game completion, with 11 time slices for the 11 storms. Table 5 prints posterior mastery per skill per slice; the article notes "precipitation type and wind speed showed extremely low mastery probabilities for most time slices". No effect size is printed.
"According to Table 5, wind direction and air movement showed the highest posterior mastery probabilities, 0.69 and 0.64, respectively."
Discussion¶
Related Claims¶
- Learning curves show error rates decreased for wind direction, air movement, and cloud type but stayed high for wind speed and precipitation skills — related
- BKT estimates show most students mastered wind direction and air movement but few mastered wind speed, precipitation type, or amount — related
- Both BKT and DBN show high classification accuracy but low consistency for wind direction, cloud type, and air movement — related
