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? Mean achievement was rather flat across the first three measures and dropped markedly on the fourth, attributed to the increasing complexity of learning unit 4. → Angel Blanch 2015

Descriptive analysis of the four achievement means and variances in the BURN11 dataset. The article attributes the drop in the last measure to the increasing difficulty of learning unit 4, where the full Xenograde System was presented.
"Figure 1 shows the means and variances, indicating that the achievement growth process fluctuated across the four observation points as a sinusoid-like pattern, with a rather flat growth in the first three achievement measures, and with a pronounced drop in the last achievement measure."
Discussion¶
Related Claims¶
- Final achievement level and rate of achievement change were positively correlated: students with higher final levels experienced smaller achievement decrements
- A pronounced drop in performance occurs at week 8 after the first exam in an area of law, which is attributed to cyclic drops in motivation — related
- Quadratic latent growth fits MAP longitudinal achievement data better than linear growth across ten states — a broader claim this one bears on
- For Han students, metacognitive knowledge followed a quadratic (accelerating) growth model while vocabulary breadth followed a linear growth model, and initially high vocabulary knowledge predicted faster later vocabulary growth — a broader claim this one bears on
- Motivation and engagement relate cyclically: prior motivation predicts subsequent engagement and prior engagement predicts subsequent motivation — related
