A Technical Note on IRT Simulation Studies: Dealing With Truth,Estimates, Observed Data,and Residuals 下载免费PDF全文
Simulation studies are extremely common in the item response theory (IRT) research literature. This article presents a didactic discussion of “truth” and “error” in IRT‐based simulation studies. We ultimately recommend that future research focus less on the simple recovery of parameters from a convenient generating IRT model, and more on practical comparative estimation studies when the data are intentionally generated to incorporate nuisance dimensionality and other sources of nuanced contamination encountered with real data. A new framework is also presented for conceptualizing and comparing various residuals in IRT studies. The new framework allows even very different calibration and scoring IRT models to be compared on a common, convenient, and highly interpretable number‐correct metric. Some illustrative examples are included. 相似文献

High IQ is sufficient to explain the high achievements in math and science of the East Asian peoples
Richard Lynn 《Learning and individual differences》2010,20(6):567-568
It is argued that it is unnecessary to propose that Confucian values explain the high achievements in math and science of the North East Asian peoples, and that these can be satisfactorily and more parsimoniously be explained by their high IQs. 相似文献

This study explored deaf and hearing university students’ metacognitive awareness with regard to comprehension difficulties during reading and classroom instruction. Utilising the Reading Awareness Inventory (Milholic, V. 1994. An inventory to pique students’ metacognitive awareness of reading strategies. Journal of Reading 38: 84–6), parallel inventories were created to tap metacognitive awareness during comprehension of sign language (deaf students) and spoken language (hearing students). Overall, both deaf and hearing students appeared to have greater metacognitive awareness of ongoing comprehension and repair strategies during reading than during instruction in the classroom, but deaf students scored lower than hearing students in both modalities. Deaf students were no more likely than hearing students to report adopting inappropriate strategies, but both groups indicated they were more likely to do so in classroom contexts than during reading. 相似文献
