This study evaluated the effectiveness of intervention for developing deaf and hard-of-hearing (DHH) preschoolers' phonological awareness (PA) skills. Thirty children (mean age 57 months) with aided, bilateral hearing loss (and who primarily communicated using spoken English) were recruited in the year prior to commencing formal schooling. The…

This methodological brief introduces basic procedures and issues for conducting a high-quality meta-analysis in gifted education. Specifically, we discuss issues such as how to select a topic and formulate research problems, search for and identify qualified studies, code studies and extract data, choose and calculate effect sizes, analyze data,…

This document presents the technical appendices that accompany the full report, "Determining College Readiness in California's Community Colleges: A Survey of Assessment and Placement Policies." The appendices include: (1) Survey Design and Administration; and (2) Survey Instrument. [This report was written with research support from…

The purpose of this study was to explain the variability in data collected from a single-case design study and to identify predictors of communicative outcomes for children with developmental delays or disabilities (n = 4). Using SAS® University Edition, we fit multilevel models with time nested within children. Children's level of baseline…

Survey research in education is a popular quantitative research design and is used to determine opinions, attitudes, behavior, habits, and perceptions on a wide variety of topics. While many people are familiar with survey methods, it is often used in a 'quick and dirty' way to get information. This case aims to describe some of the challenges of…

This review protocol from the What Works Clearinghouse (WWC) covers the following issues relevant to screening criteria and full review for the Access to Higher Education Practice Guide: (1) time frame; (2) study design; (3) age and/or grade range; (4) brief description of intervention; (5) key subgroups; (6) location and language; (7) outcomes…

Reviewers performing systematic literature reviews require understanding of the review process and of the knowledge domain. This paper presents an iterative approach for conducting systematic literature reviews that addresses the problems faced by reviewers who are novices in one or both levels of understanding. This approach is derived from…

Too often, students don't feel engaged in their research projects. The problem begins as early as the topic-creation stage, when students may choose from a list of teacher-selected topics that don't interest them or struggle to select a single fruitful topic on their own. Nanci Werner-Burke describes how two students in an English…

Educating children on a global level is a dynamic process where policy, procedure and guideline changes can leave teachers searching for new programs to resolve new challenges. This brief report shows a successful application of the Good Behavior Game in a school in the country of Belize following a significant change in policy regarding…

The authors compared the effects of using the true Multilevel Latent Growth Curve Model (MLGCM) with single-level regular and design-based Latent Growth Curve Models (LGCM) with or without the higher-level predictor on various criterion variables for multilevel longitudinal data. They found that random effect estimates were biased when the…

It is essential to teach students about experimental design, as this facilitates their deeper understanding of how most biological knowledge was generated and gives them tools to perform their own investigations. Despite the importance of this area, surprisingly little is known about what students actually learn from designing biological…

Researchers often use generalizability theory to estimate relative error variance and reliability in teaching observation measures. They also use it to plan future studies and design the best possible measurement procedures. However, designing the best possible measurement procedure comes at a cost, and researchers must stay within their budget…

Randomized experiments are often seen as the "gold standard" for causal research. Despite the fact that experiments use random assignment to treatment conditions, units are seldom selected into the experiment using probability sampling. Very little research on experimental design has focused on how to make generalizations to well-defined…

This report describes the approach that REL Northeast and Islands (REL-NEI) used to guide its eight research alliances toward collaboratively identifying a shared research agenda. A key feature of their approach was a two-workshop series, during which alliance members created a set of research questions on a shared topic of education policy and/or…

The limit concept is a fundamental mathematical notion both for its practical applications and its importance as a prerequisite for later calculus topics. Past research suggests that limit conceptualizations promoted in introductory calculus are far removed from the formal epsilon-delta definition of limit. In this article, I provide an overview…
