Estimating Variance Components from Sparse Data Matrices in Large-Scale Educational Assessments

In generalizability theory studies in large-scale testing contexts, sometimes a facet is very sparsely crossed with the object of measurement. For example, when assessments are scored by human raters, it may not be practical to have every rater score all students. Sometimes the scoring is systematically designed such that the raters are consistently grouped throughout the scoring, so that the data can be analyzed as raters nested within teams. Other times, rater pairs are randomly assigned for each student, such that each rater is paired with many other raters at different times. One possibility for this scenario is to treat the data as if raters were nested within students. Because the raters are not truly independent across all students, the resulting variance components could be somewhat biased. This study illustrates how the bias will tend to be small in large-scale studies.

Learning the rules of the game: The role of generic “you” and “we” in shaping children's interpretations of norms

A critical skill of childhood is learning social norms. We examine whether the generic pronouns “you” and “we,” which frame information as applying to people in general rather than to a specific individual, facilitate this process. In one pre-registered experiment conducted online between 2020 and 2021, children 4- to 9-year-old primarily living in the midwestern U.S. (N = 146, 75 girls, 71 boys, M_age = 7.14, SD = 1.69, 82% White) interpreted actions described with generic pronouns (vs. “I”) as normatively correct and selected the speaker who used generic pronouns as the rule-follower, particularly when generic pronouns were presented first. There were no significant effects of age. These results illustrate how generic pronouns influence how children discern unfamiliar norms and form interpersonal judgments.

Who determines teacher work: The teacher,the organization,or both?

This paper examines how teachers responded when some organizational constraints on their work were loosened and why they responded as they did. It first reviews the sociological literature on teacher work to identify the main determinants studied. It then presents results of an ethnographic study of teachers in an urban school. The literature tends to portray teacher work as overly determined and may remove more responsibility from teachers for determining their own work than is warranted.     

Infants Prefer Infant‐Directed Song Over Speech

In their everyday communication, parents do not only speak but also sing with their infants. However, it remains unclear whether infants' can discriminate speech from song or prefer one over the other. The present study examined the ability of 6‐ to 10‐month‐old infants (N = 66) from English‐speaking households in London, Ontario, Canada to discriminate between auditory stimuli of native Russian‐speaking and native English‐speaking mothers speaking or singing to their infants. Infants listened significantly longer to the sung stimuli compared to the spoken stimuli. This is the first study to demonstrate that, even in the absence of other multimodal cues, infant listeners are able to discriminate between sung and spoken stimuli, and furthermore, prefer to listen to sung stimuli over spoken stimuli.
