The aim of this longitudinal study was to examine spelling acquisition in French children with developmental language disorder (DLD) over a school year. Through a fine-grained spelling error analysis, we investigated whether spelling profiles could be established in the DLD population. This study comprised three groups: a typically developing (TD)…

Because random assignment is not possible in observational studies, estimates of treatment effects might be biased due to selection on observable and unobservable variables. To strengthen causal inference in longitudinal observational studies of multiple treatments, we present 4 latent growth models for propensity score matched groups, and…

This study looks at the question of whether charter schools are more innovative in their provision of extended time policies than a matched set of traditional public schools. Data for this study was collected from a sample of traditional public and charter schools that partner with the Northwest Evaluation Association (NWEA) for interim…

Providing exploratory activities prior to explicit instruction can facilitate learning. However, the level of guidance provided during the exploration has largely gone unstudied. In this study, we examined the effects of 1 form of guidance, feedback, during exploratory mathematics problem solving for children with varying levels of prior domain…

Objective: To examine the effects of a school garden on children's fruit and vegetable knowledge, preference, and consumption. Design: Self-report questionnaires, interview-style taste and rate items, lunchroom observations. Setting: An elementary school. Participants: Second-grade students (n = 115). Intervention: Participants were assigned to…

This study evaluated the effects of a fluency-based reading program with 15 second and third grade students and 15 matched controls. Gains in oral reading fluency on untrained CBM probes were evaluated using a matched-pairs group-comparison design, whereas immediate and two-day retention gains in oral reading fluency on trained passages were…

This action research project was conducted in a 2nd-grade classroom in the Midwest to determine the effects of technology on responses to texts. Six texts, representing a variety of rending levels, were selected for the children to read. Children in the control group read and did research from printed texts, and children in the treatment group…
