To better…

Researchers in educational measurement use Differential Item Functioning (DIF) to examine whether test items are functioning uniquely across subgroups of test participants while taking into account their ability level. DIF is essential for test validity arguments, thus making it a necessary part of validity studies. This study examines DIF across…

Teachers play a crucial role in the diagnostic process of Attention-Deficit/Hyperactivity Disorder (ADHD) in students: They are often the first to identify ADHD-related behaviors in children and to signal them to parents. Research has demonstrated that the recognition and labeling of certain behaviors as evidential for ADHD by teachers vary with…

We applied…

Children born with very low birth weight (VLBW <1500 g) have a high risk of reading difficulties. Previous research has suggested that poor reading skills in VLBW children are associated with attention problems. In the current study, we examined the eye movements in VLBW children during reading and investigated their relationship with…

In this paper we use data from students who participated in the oversubscribed Boston Public Schools (BPS) prekindergarten program as a window into variation in the program's medium-term effects. We first examine whether, for the sample of students who applied to oversubscribed BPS prekindergarten programs, there is variation in the effects of the…

We examined the associations of cognitive skills, math-related emotions and beliefs, and gender with responses to an arithmetic fluency intervention. Elementary school children with dysfluent arithmetic skills (N=69) participated in an arithmetic fluency intervention (with and without self-efficacy support) implemented in small groups in schools…
