The study addressed the gap in fifth-grade science proficiency between English language learners (ELLs) enrolled in two different science programs in a large school district in the Southeast United States. The Inspire program was implemented in 125 schools, while a combination of Inspire and Promoting Science among English Language Learners…

Research shows that assuming a test scale is equal-interval can be problematic, especially when the assessment is being used to achieve a policy aim like evaluating growth over time. However, little research considers whether teacher value added is sensitive to the underlying test scale, and in particular whether treating an ordinal scale as…

The purpose of this study was to determine the effectiveness of an instructional package, Self-Regulated Strategy Development, a cognitive strategy instructional model (POW + TREE), in combination with video self-modeling (VSM) on the improvement on the written expression of three third-grade students with learning disabilities (LD).

This study defines subpopulation item parameter drift (SIPD) as a change in item parameters over time that is dependent on subpopulations of examinees, and hypothesizes that the presence of SIPD in anchor items is associated with bias and/or lack of invariance in three psychometric outcomes. Results show that SIPD in anchor items is associated…

In this study, we compare the teacher quality distributions in charter schools and traditional public schools, and examine mechanisms that might explain cross-sector differences in teacher effectiveness as measured by teacher value-added scores using school and teacher level data from Florida. We have three main findings. First, we find that…

Underachievement among gifted students is a paradox that frustrates educators because of the significant disparity between students' potential and their performance. Complicating the issue is the highly individualized nature of the underperformance, which must take into consideration factors of student culture, socio-economic status, motivation,…

The pressure to have students perform well on standardized tests can serve as a stressor to some teachers in their efforts to autonomously teach their students, particularly those of low socioeconomic status (SES). However, the relationship between teachers' sense of autonomy, teachers' attitudes and behaviors, SES, and student's academic success…
