Background and Aims: Students with intellectual disability benefit from high-quality instruction in reading and mathematics. Methods: This Theoretical Paper outlines the need for effective, evidence-based instructional practices for this population and the potential for observation research to inform such advancements. We report our systematic…

While an abundance of evidence-based mathematics interventions are available to support students' mathematics fluency, research suggests that they are not often implemented within schools. Moreover, national data suggests that most students in the United States are not meeting grade level expectations in mathematics. This underperformance coupled…

Fraction knowledge is an essential building block for successful completion of advanced mathematics courses and linked to the development of algebraic understanding. Many students, especially those with disabilities, experience significant difficulties developing fraction knowledge. Intensive fraction interventions have been shown to be effective…

Research shows that that children learn science and engineering subjects best by engaging from an early age in the kinds of practices used by real scientists and engineers. By doing science and engineering, children not only develop and refine their understanding of the core ideas and crosscutting concepts of these disciplines, but can also be…

Fraction proficiency is a critical milestone for students to reach, as fraction knowledge strongly predicts later math achievement. However, fractions are notoriously difficult for students to learn. The first study in this dissertation reviewed commonly used math curricula to determine if their fraction lessons used evidence-based instructional…

Purpose: The purpose of this scoping review was to document how the literature reports morphological awareness instruction and interventions delivered by speech-language pathologists (SLPs) and/or educators in classroom settings for kindergarten to Grade 3 students. Method: We followed the Joanna Briggs Institute's methodology for scoping reviews…

Teaching linguistic aspects relevant to text construction is an essential component of any thorough writing instruction program, despite the conflicting evidence regarding its effectiveness. In this study, 889 second- and fourth-grade students were assigned to one of three conditions: Self-Regulated Development (SRSD), SRSD-connectors (SRSD-C),…

In the teaching of math-fact automaticity, most classroom teachers are unaware of research-based practices such as the use of a controlled response time, the scaffolded teaching of individual math facts, the limiting of exposure to new math facts, the separation of math facts with common operands, and even the definition of automaticity. As a…

The purpose of this systematic observation study was to improve our understanding of small-group reading instruction for kindergarten students at risk for reading difficulties (RDs). We aimed to observe and document activity types addressed as well as instructional practices and materials employed during small-group instruction, with a particular…

The quality of care in public schools and other community settings for school-aged youths on the autism spectrum is variable and often not evidence-based. Training practitioners in these settings to deliver evidence-based practices (EBPs) may improve the quality of care. We developed a free internet-based training and clinical guidance system…

LXD Research analyzed data from 402 students from second and third graders who either participated in using the 95 Phonics Core Program (95PCP) or served as comparison students in a school district in AZ during the school year 2022-2023. This product adds explicit and systematic phonics instruction to the daily reading block. The demographic…

A pre-test post-test design was used to deliver the Size Matters Handwriting Program to 19 second-grade students using an occupational therapist-teacher collaborative teaching model. Outcomes from the Minnesota Handwriting Assessment indicate statistically and clinically significant gains for students in legibility, form, alignment, size, and…

While AI has become more prevalent in our society than ever, many young learners are found holding various naive, erroneous conceptions of AI due to the influence of their technology and media environments. To address this issue, this study seeks to propose a novel pedagogical solution to improve upper-elementary school students' scientific…

This article describes an intervention program to improve writing skills, intended to be a useful tool for everyday remedial work in primary school. The design was based on an initial review of the approaches most often used for writing intervention and identification of the main concerns for such intervention; namely, the use of direct and…
