This quantitative study intends to better understand the impact of the location of the first deleted word upon the estimation of text difficulty yielded by successive cloze tests based on random deletion from a single passage. The variation in sampling of language features across five cloze tests based on the same passage is random and thus not…

This activity makes students a part of an investigation that determines the frequency of a particular plant variety in a simulated population. Provides an opportunity for students to observe the inherent variability of estimates, observe the relationship between sample size and sampling error, and consider aspects of research design.

A performance assessment score is viewed as a sample of student performance drawn from a complex universe defined by a combination of all possible tasks, occasions, raters, and measurement methods. Using generalizability theory, the authors present evidence bearing on the…
