Many studies conducted in the last decades report that very few elementary-grades students understand the meaning of = in mathematics, and that upper-elementary students do not understand it any better than the lower-elementary students do. Using data from thousands of Florida elementary students, we show that students in Florida perform ten to…

In this chapter, we discuss the algebra framework that guides our work and how this framework was enacted in the design of a curricular approach for systematically developing elementary-aged students' algebraic thinking. We provide evidence that, using this approach, students in elementary grades can engage in sophisticated practices of algebraic…

School-aged English Learners (ELs) are faced with the challenging task of acquiring a foreign language while simultaneously reading academically demanding literature. Therefore, the current research aimed to examine the relation between the rate of grammatical tense marking errors made by ELs and their performance on measures of reading…

This study aimed to describe 2nd-grade teachers' use of different forms of praise during English Language Arts (ELA) instruction and examine if teacher characteristics were associated with differences in the use of different types of praise. Investigators recorded 2nd-grade teachers' language use during randomly selected, 15-min excerpts (n = 912)…

The purpose of this preliminary study was to examine the extent to which the relation between teacher reported (N = 26) teaching efficacy and observations of classroom quality varied as a function of a specific classroom characteristic, classroom adversity, a measure of classroom level hardship that includes factors such as student challenges with…

Successful implementation of school-wide interventions (i.e., delivered to all students by a wide array of school personnel) is key to promoting students' academic achievement and psychosocial development. Yet, the implementation of school-wide interventions is complex and can be psychologically taxing for implementing personnel. If evidence-based…

Students in the elementary grades often experience difficulty setting up and solving word problems. Using an equation to represent the structure of the problem serves as an effective tool for solving word problems, but students may require specific pre-algebraic reasoning instruction about the equal sign as a relational symbol to set up and solve…

Background: Educators in rural schools are uniquely situated to address youth mental health disparities, yet often face challenges in delivering mental health supports. This paper describes the process of adapting the evidence-based Coping Power program, a small group prevention program for youth with aggressive behavior problems, to be a…

Teachers' knowledge and skills about data-based instruction (DBI) can influence their self-efficacy and their implementation of DBI with fidelity, ultimately playing a crucial role in improving student outcomes. The purpose of this brief report is to provide evidence for the technical adequacy of a measure of DBI knowledge and skills in writing by…

The goals of the study were to (a) examine teacher-reported acceptability of a daily report card (DRC) intervention for a student in their classroom prior to and during implementation; (b) examine factors that predict acceptability; and (c) explore the relations between teacher-reported acceptability, student and teacher characteristics prior to…

The purpose of this study was to assess the quality of educational programs for school-aged children with autism in the United States. Investigators completed the Autism Program Environment Quality Rating Systems-Preschool/Elementary (APERS) in 60 elementary schools enrolling children with autism. The mean total rating scores were near the…

We propose a framework designed to guide the development of automated writing practice and formative evaluation and feedback for young children (K-5 th grade) -- the early Automated Writing Evaluation (early-AWE) Framework. e-AWE is grounded on the fundamental assumption that e-AWE is needed for young developing readers, but must incorporate…

Despite increasing reliance on licensed practical nurses (LPNs) to provide health services in schools, we do not know whether this is a cost-effective prevention strategy against student absenteeism. Therefore, we evaluated the costs and effectiveness of an LPN-based school nursing program for improving attendance and chronic absenteeism at a…

Although variable-oriented analyses are dominant in developmental psychopathology, researchers have championed a person-oriented approach that focuses on the individual as a totality. This view has methodological implications and various person-oriented methods have been developed to test person-oriented hypotheses. Configural frequency analysis…

This study examines the efficacy, cost, and implementation of an integrated science and literacy curriculum for kindergarten. The study was conducted in a large urban district and included 1,589 students in 71 classrooms in 21 schools. The research includes a multi-site cluster-randomized controlled trial and mixed-methods cost and implementation…
