An Empirical Comparison of DDF Detection Methods for Understanding the Causes of DIF in Multiple-Choice Items

This study compared and illustrated four differential distractor functioning (DDF) detection methods for analyzing multiple-choice items. The log-linear approach, two item response theory-model-based approaches with likelihood ratio tests, and the odds ratio approach were compared to examine the congruence among the four DDF detection methods. Data from a college-level mathematics placement test were analyzed to understand the causes of differential functioning. Results indicated some agreement among the four detection methods. To facilitate practical interpretation of the DDF results, several possible effect size measures were also obtained and compared.     

Implementing a Multi-Tiered System of Support (MTSS): Collaboration Between School Psychologists and Administrators to Promote Systems-Level Change

Current educational reform mandates the implementation of school-based models for early identification and intervention, progress monitoring, and data-based assessment of student progress. This article provides an overview of interdisciplinary collaboration for systems-level consultation within a Multi-Tiered System of Support (MTSS) framework. The roles of school psychologists and school-based administrators are presented in relation to the implementation of MTSS practices within an implementation science model. The training and expertise of each discipline are highlighted related to respective aspects of implementation drivers (i.e., competency, organization, leadership). Functions of principals and school psychologists during team-based, problem-solving MTSS practices are described based on a problem-solving framework consistent with school-based consultation. Future directions for graduate training of school psychologists and principals and directions for consultation research are provided.     

Outside of School Matters: What We Need to Know in Urban Environments

This article focuses on factors outside of school that we have identified from the established research literature as essential for educators to consider in supporting students in urban environments. We start by conceptualizing what it means for a school to be “urban.” Following this discussion, we describe four outside-of-school factors that emerge from the literature: (1) Understanding Student and Family Homelessness; (2) Understanding Geography and Social Contexts; (3) Understanding Policy and School Funding; and (4) Understanding Parental and Family Involvement. These factors are important to helping educators, especially pre- and in-service teachers, in their understanding of and, consequently, the practices they use to meet the needs of students in these social contexts. We conclude with recommendations for educational practice.     

From Awareness to Action: College Students’ Skill Development in Intergroup Dialogue

A central goal of intergroup dialogue (IGD) is to strengthen individual and collective capacities to foster social justice commitments by supporting new ways of thinking about oneself, others, and the social structures in which we live. Relatedly, IGD assists individuals with building multicultural competencies and skill sets that support peoples’ capacities to take action and work towards social change. The following qualitative study contributes to current research by describing the types of skills undergraduate students report learning as a result of their IGD experience and the challenges they encounter as they develop communication, cognitive, and affective skills.     

Design-Based Research Within the Constraints of Practice: AlgebraByExample

Superintendents from districts in the Minority Student Achievement Network (MSAN) challenged the Strategic Education Research Partnership (SERP) to identify an approach to narrowing the minority student achievement gap in Algebra 1 without isolating minority students for intervention. SERP partnered with 8 MSAN districts and researchers from 3 universities to design and rigorously test AlgebraByExample, a set of 42 Algebra 1 assignments with interleaved worked examples that target common misconceptions and errors. In a year-long random-assignment study, students who received AlgebraByExample assignments had an average 7 percentage point boost on a posttest containing released items from state assessments, and students in the bottom half of the performance distribution where minority students are disproportionately concentrated had an average 10 percentage point boost on a researcher-designed assessment of conceptual understanding. AlgebraByExample is easily incorporated into any existing curriculum, and naturally serves as a launch point for mathematically rich discussion.     

Phonological Processing and Word Reading in Typically Developing and Reading Disabled Children: Severity Matters

In this study word reading (WR) fluency was used to dichotomously classify 1,598 Dutch children at different cutoffs, indicating (very) poor or (very) good reading performance. Analysis of variance and receiver operating characteristics were used to investigate the effects of rapid automatized naming (RAN) and phonemic awareness (PA) in predicting group membership. The highest predictive values were found for the combination of RAN and PA, particularly for the poorest readers. Furthermore, results indicate that with the severity of impairment, WR is more dominated by deficient PA, which is interpreted as an enduring problem with sublexical processing. Another main result is that with the increase of reading skill, the contribution of PA diminishes, whereas the contribution of RAN remains fairly constant for the whole reading fluency continuum. These results warrant the conclusion that whereas PA hallmarks reading disability, RAN appears to be the default predictor for above-average or excellent reading proficiency.
