Harris, Karen R.; Graham, Steve – Annals of Dyslexia, 2013
By the upper elementary grades, writing becomes an essential tool both for learning and for showing what you know. Students who struggle significantly with writing are at a terrible disadvantage. Data from the National Assessment of Educational Progress indicate that only 25% of students can be classified as competent writers; students with…

Aucejo, Esteban – Centre for Economic Performance, 2013
The sizable gender gap in college enrolment, especially among African Americans, constitutes a puzzling empirical regularity that may have serious consequences on marriage markets, male labor force participation and the diversity of college campuses. For instance, only 35.7 percent of all African American undergraduate students were men in 2004.…

Mislevy, Robert J.; And Others – 1994
It is a common practice in item response theory (IRT) to treat estimates of item parameters, say "B" circumflex, as if they were the known, true quantities, "B." However, ignoring the uncertainty associated with item parameters can lead to biases and over-confidence in subsequent inferences such as ability estimation,…

Yamamoto, Kentaro; Muraki, Eiji – 1991
The extent to which properties of the ability scale and the form of the latent trait distribution influence the estimated item parameters of item response theory (IRT) was investigated using real and simulated data. Simulated data included 5,000 ability values randomly drawn from the standard normal distribution. Real data included the results for…

Nandakumar, Ratna – 1991
Performance in assessing the unidimensionality of tests was examined for four methods: (1) W. F. Stout's procedure (1987); (2) the approach of P. W. Holland and P. R. Rosenbaum (1986); (3) linear factor analysis; and (4) non-linear factor analysis. Each method was examined and compared with the others using simulated and real test data. Seven data…

Donoghue, John R.; Mazzeo, John – 1995
At grades 8 and 12, the 1992 National Assessment of Educational Progress (NAEP) reading assessment contained a small number of 50-minute blocks in addition to the usual 25-minute blocks. To determine whether to incorporate the 50-minute blocks into the operational scaling, this study sought to determine whether the longer blocks measured a…
