This study examined the effects of training involving spatial versus nonspatial representations of numerical magnitude for promoting arithmetic fluency. The key goal was to advance theoretical understanding of the relation between spatial and math learning, while simultaneously laying the groundwork for the development of future educational…

The purpose of this study was to examine teachers' perceptions of the Illustrative Mathematics (IM) using data from teacher interviews from year 1 and year 3 of their implementation of IM. In year 1, 22 Algebra 1 teachers were interviewed; in year 3, 13 teachers participated. Interviews were conducted using a semi-structured protocol that included…

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…

Student motivation to write is a pivotal factor influencing their writing achievement. However, individual motivation to write is not independent of the learning environment. It also is crucial for teachers to develop their own efficacy, knowledge, and ability in writing and writing instruction to help them utilize effective instructional methods…

This article examines the professional knowledge required for mathematics teachers to effectively use generative artificial intelligence (GenAI) in planning high-quality, ambitious mathematics lessons. While GenAI tools like ChatGPT offer promise for automating parts of lesson planning, their utility in supporting ambitious instruction is limited…

Developing young children's vocabulary is essential for later reading success; thus, early childhood classrooms require a comprehensive vocabulary approach that teaches academic vocabulary. Yet even providing young children with child-friendly definitions of sophisticated words can be a challenge. First, the authors outline the components of a…

Past research has suggested that there may be benefits in learning from expository science text when students study with the expectation that they will need to teach another student. The present experiments were designed to extend prior work by testing if an effect would be seen on both immediate tests (similar to those used in most prior studies)…

A small proportion of students do not benefit sufficiently from standard intervention protocols, and require more intensive, individualized instruction. Data-Based Instruction (DBI) has a strong evidence base for addressing students' intensive academic needs, yet it is not widely implemented. In this study, we explored the usability and…

Expanding on the extant body of research on content validity, this study applied the tenets of content validity research to the development of an expository book reading intervention focused on science for preschool students with language impairment. This example case explains how, guided by content validity research in healthcare interventions,…

Empirically supported multimedia learning (MML) principles [1] suggest effective ways to design instruction, generally for elements on the order of a graphic or an activity. We examined whether the positive impact of MML could be detected in larger instructional units from a MOOC. We coded instructional design (ID) features corresponding to MML…

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

Purpose: This paper describes the iterative development of a home review program designed to augment vocabulary instruction for young children (ages 4 and 5) occurring at school through the use of a home review component. Method: A pilot study followed by two experiments used adapted alternating treatment designs to compare the learning of…

Main idea and summary are essential elements of reading comprehension. We report results from Grades 4 and 5 student performance on two years of state-mandated standardized reading testing which indicate that students perform statistically significantly lower on main idea and summary questions on the tests than any other question category. In this…

This article describes the importance of vocabulary knowledge in adolescents' reading comprehension, particularly for students with disabilities. Students with stronger vocabularies tend to have better background knowledge and improved understanding of content-area texts. We describe evidence-based vocabulary instructional practices that…

Vocabulary knowledge is vital for students' success in school and beyond. However, students with disabilities and others who consistently score below their peers on various measures of vocabulary knowledge have difficulties in secondary-level content area courses. Because many students with disabilities are now educated primarily in general…
