This study evaluates the impacts and costs of the Reading Partners program, which uses community volunteers to provide one-on-one tutoring to struggling readers in under-resourced elementary schools. The evaluation uses an experimental design. Students were randomly assigned within 19 different Reading Partners sites to a program or control…

Adopting a multitiered design-based research perspective, this study examines pre-service secondary mathematics teachers' developing conceptions about (a) the nature of mathematical modeling in simulations of "real life" problem solving, and (b) pedagogical principles and strategies needed to teach mathematics through modeling. Unlike…

Few studies have explored the learning difficulties and misconceptions that students encounter when using information and communication technology for e-learning. To address this issue, this research developed a system for evaluating the learning efficiency of medical students by applying two-tier diagnosis assessment. The effectiveness of the…

Systematic, practical, and accessible, this is the first book to focus on finding the most defensible design for a particular research question. Thoughtful guidelines are provided for weighing the advantages and disadvantages of various methods, including qualitative, quantitative, and mixed methods designs. The book can be read sequentially or…

This NCEE Technical Methods Paper compares the estimated impacts of an educational intervention using experimental and regression discontinuity (RD) study designs. The analysis used data from two large-scale randomized controlled trials--the Education Technology Evaluation and the Teach for America Study--to provide evidence on the performance of…

Companies constantly adapt to new business environments in order to be successful and stay relevant. Innovation is a vital source for a company to be competitive in the business environment. Innovations enable companies to develop and utilize new strategies, tools, and tactics as well as new products and services. Enterprise resource planning…

Single case designs are a set of research methods for evaluating treatment effects by assigning different treatments to the same individual and measuring outcomes over time and are used across fields such as behavior analysis, clinical psychology, special education, and medicine. Emerging standards for single case designs have focused attention on…

This conference presentation demonstrates a multilevel model for analyzing single case designs. The model is implemented in the Bayesian program WinBUGS. The authors show how it is possible to estimate a d-statistic like the one in Hedges, Pustejovsky and Shadish (2012) in this program. Results are demonstrated on an example.

Current research suggests a link between negative attitudes toward women and violence against women, and it also suggests that media may condition such negative attitudes. When considering the tremendous and continued growth of video game sales, and the resulting proliferation of sexual objectification and violence against women in some video…

The purposes of this paper are to (a) propose an operational standard for defining a "practice," (b) encourage development of professional standards for visual and statistical analysis of single-case research, and (c) propose a standard for using single-case research results to identify practices that are "evidence-based." These topics are not new…

In this article, the authors examine the interconnections among education researchers' misconceptions about the quality of the education research literature. Specifically, the authors catalog the sequence of events that, when taken together with a series of contradictory graphs presented by influential scholars in prominent settings, may have…

The present article responds briefly to the comments, in this issue of "Educational Researcher," of Petrosino and of Robinson to the "Propagation of Misinformation About Frequencies of RFTs/RCTs in Education: A Cautionary Tale." The authors emphasize that the context of how the quality of education research is perceived both within and outside the…

The call for researchers to report and interpret effect sizes and their corresponding confidence intervals has never been stronger. However, there is confusion in the literature on the definition of effect size, and consequently the term is used inconsistently. We propose a definition for effect size, discuss 3 facets of effect size (dimension,…

Patterns of articles accepted for publication in the "Journal of College Counseling" from the past 12 years were reviewed in this metastudy. Results were described and statistically analyzed to identify trends over time in characteristics of authors, including sex, institutional classifications, employment setting, and domicile, and…

The single-case research design has become a paradoxical methodology in the applied sciences. While various experimental designs have been in place for over 50 years, there has not been wide acceptance of single-case methodology outside clinical and school psychology, or the field of special education. These methods were developed in the U.S.A.,…
