When student achievement is assessed, we seek to elicit a student's maximum performance -- a goal requiring the assumption that the student is fully engaged. Otherwise, to the extent that disengagement occurs, test performance is likely to suffer. Effectively managing test-taking disengagement requires an understanding of the testing conditions…

Under the Individuals with Disabilities Education Act, schools are required to provide a free appropriate public education to students with disabilities and show that the students are making academic progress. This study compares within- and across-years academic growth from kindergarten to 4th grade for students who were ever in special education…

The COVID-19 pandemic disrupted education worldwide as educational systems made the decision to close schools to contain the spread of the virus. The duration of school closures varied greatly internationally. In this study, we use representative trend data from more than 300,000 students in 29 countries to examine whether the cross-country…

To examine developmental processes, intervention effects, or both, longitudinal studies often aim to include measurement intervals that are equally spaced for all participants. In reality, however, this goal is hardly ever met. Although different approaches have been proposed to deal with this issue, few studies have investigated the potential…

The purpose of this study was to examine the relationship between elementary instructional content minute allocations and academic growth. The study sought to explore the relationship between instructional content allocations, scheduling, and the use of content time on student achievement growth. Additionally, the study sought to uncover the…

In this study, we investigated longitudinal reciprocal relations among reading, executive function, and social-emotional skills in students from Grades 2 to 5, using the data set from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011. We addressed several important gaps in the literature on longitudinal reciprocal relations…

Math education consultant Marilyn Burns finds that teachers ask her the same three questions so often she's named them "The Big Three": What can I do with students who finish their math work more quickly?, How can I free up time to work with kids who need extra help?, and How can I differentiate math learning experiences? Burns, who…

For the effective expression of feelings and thoughts, handwriting should be produced fluently at a certain speed. The aim of this study was to examine the development of handwriting speeds in 4th-8th grade primary and secondary school students in terms of some variables. In line with this aim, answers were sought to the question, "Do 4th-8th…

At the local site, many students were not achieving necessary learning gains on state assessments. Administrators and teachers were concerned as to why students on the local level were falling short. Current trends emphasized differentiation of instruction in classrooms to meet individual student needs; however, classrooms generally adhere to a…

We investigated whether the cool and hot executive functions (EFs) exhibited by kindergarteners could predict their academic achievement in the middle grades of elementary school. The study assessed the cool and hot EF of 48 Japanese kindergartners (M = 78.12 months) and then measured these same children's academic achievement in language and…

Fraction knowledge has been found to predict later mathematical performance, but many students have difficulty with fractions. Virtual manipulatives (VM) and concrete manipulatives (CM) are effective approaches to teaching fractions, but previous research has not been able to reach a consensus on which manipulatives are the most effective. This…

Barriers to well-being detract from teachers' effectiveness, however there is limited understanding of exactly how this occurs. We explored whether fourth grade teachers' (N=65) burnout symptoms related to their lesson length in mathematics, science, and English Language Arts, and to time in each of three classroom groupings. Multiple regression…

Following a massive wave of school closures during the COVID-19 pandemic, educators found the need to be hyper-critical of how they spend their instructional time with students. Almost all students are expected to return nearly a full grade-level behind and would likely have to learn to navigate a completely new school environment. As a result,…

General cognitive and specific numerical abilities that underlay mathematical performance have been heavily investigated among hearing students; however, the inquiry has rarely been applied to students who are deaf or hard-of-hearing (d/Dhh). We examined whether general cognitive abilities (i.e. nonverbal IQ, processing speed, and spatial ability)…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…
