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.
q3 i2 WHP adopters assigned summative activities with higher historical thinking rubric scores than comparison teachers (Hedges' g = .66). → Iwatani 2023
Evidence¶
Iwatani 2023¶
Iwatani, E., Hardy, A., Means, B., Daal, S., & Wei, X. (2023). Evaluation of World History Project. Digital Promise. https://doi.org/10.51388/20.500.12265/199
q3 · i2 · causal · r2
Quasi-experimental comparison of 119 WHP and 149 comparison curricular activity samples, triple-scored by blinded trained scorers on 4-point historical thinking rubrics. The report states the summative-overall difference favored "World History Project" with "Hedges' g = .66".
"We found statistically significant impact estimates on learning opportunities for historical thinking skills, favoring the use of World History Project in: summative activities overall ( M WHP = 1.77, M Comp = 1.29, β = .56, SE = .24, p = .018, Hedges' g = .66)"
Discussion¶
Related Claims¶
- Rubric scoring supports answering diagnostic questions about opportunities for and evidence of historical thinking — a broader claim this one bears on
- An evaluation of the World History Project detected no statistically significant difference from comparison students in the other five historical thinking skills — related
- World History Project does not engage students more than business-as-usual curricula on first implementation, with somewhat negative perception trends — related
- Teachers find World History Project overwhelming in their initial adoption year and make substantial modifications across three main categories — related
- World History Project assignments scored higher on most learning opportunity rubric dimensions than other assignments — possibly the same claim (merge candidate)
- Students learning from World History Project demonstrate more understanding of continuity and change over time in history than comparison students — related
- Trained scorers applied the historical thinking skills rubrics with good overall inter-rater consistency — related
- Two rubric dimensions (claims and evidence, comparison) showed low inter-scorer consistency in the pilot — related
- Scorers found all rubric dimensions important, with feedback bearing mainly on the scoring and training process rather than rubric design — related
- Six historical thinking dimensions — historical argumentation, causation, comparison, contextualization, continuity and change over time, and sourcing — were selected as rubric assessment targets based on convergence across U.S. national frameworks and the WHP course guide — related
