Consultation is beneficial for increasing teachers' intervention use for target students. However, little is known about teachers' generalized intervention use. This study is a systematic replication of Riley-Tillman and Eckert ("J Educ Psychol Consult" 12:217-241, 2001) and Martens et al. ("Sch Psychol Q" 12:33-41,…

This is a study of district internal salary distribution practices and its effect on retention. The study is a replication study as recommended by Jacobson (1986) and Lankford and Wyckoff (1997) whereby their research shows the prevalence of "back loading" and ineffectiveness relative to retention. In the case of this study, the…

A reproducibility crisis afflicts a wide range of scientific and social-scientific disciplines, from epidemiology to social psychology. Improper research techniques, lack of accountability, disciplinary and political groupthink, and a scientific culture biased toward producing positive results together have produced a critical state of affairs.…

The present study examined the effects of the Class-Wide Function-Related Intervention Team (CW-FIT) program, a group contingency intervention addressing the on-task and disruptive behavior of students with or at risk for emotional behavior disorders (EBD). Twenty-one elementary schools, 155 general education teachers, and 324 students…

A key question facing teacher evaluation systems is how to combine multiple measures of complex constructs into composite indicators of performance. We use data from the Measures of Effective Teaching (MET) study to investigate the measurement properties of composite indicators obtained under various conjunctive, disjunctive (or complementary),…

Public school district leadership is dominated by males while teaching is dominated by females (Blount, 1998; Glass, Björk, & Brunner, 2000; Grogan, 1996). Some may not recognize this as a problem while others might refer to this underrepresentation as a glass ceiling, a sticky floor, a concrete wall, or a glass cliff. In any case, the…

Two-phase designs in epidemiological studies of autism prevalence introduce methodological complications that can severely limit the precision of resulting estimates. If the assumptions used to derive the prevalence estimate are invalid or if the uncertainty surrounding these assumptions is not properly accounted for in the statistical inference…

Purpose: Our objective was to replicate previous cross­linguistic findings by comparing Portuguese and U.S. children with respect to (a) effects of language, gender, and age on vocabulary size; (b) lexical composition; and (c) late talking. Method: We used the Language Development Survey (LDS; Rescorla, 1989) with children (18-35 months) learning…

The present study replicated the methods and data analysis of Crawford Camiciottoli's (2001) study on second language (L2) reading behavior of academic English-as-a-foreign-language students. Using the original study's questionnaire, we investigated 60 advanced non-academic English-as-a-second-language learners' L2 reading frequency and attitude.…

Recent results from Vo and Wolfe (2012b) suggest that the application of memory to visual search may be task specific: Previous experience searching for an object facilitated later search for that object, but object information acquired during a different task did not appear to transfer to search. The latter inference depended on evidence that a…

This experimental study replicated Curry and Kasser's (2005) research that tested whether coloring a mandala would reduce anxiety. After inducing an anxious mood via a writing activity, participants were randomly assigned to three groups that colored either on a mandala design, on a plaid design, or on a blank paper. Anxiety level was measured…

This study examined potential differences in vocabulary found in picture books and adult's speech to children and to other adults. Using a small sample of various sources of speech and print, Hayes observed that print had a more extensive vocabulary than speech. The current analyses of two different spoken language databases and an assembled…

Ratio and proportional relationships are of primary importance during the upper elementary and middle school grades (Kilpatrick, Swafford, & Findell, 2001; National Council of Teachers of Mathematics, 1989, 2000; National Mathematics Advisory Panel [NMAP], 2008). These relationships, along with the interrelated topics of fractions, decimals,…

Retention is a complex issue of great importance to community colleges. Several retention models have been developed to help explain this phenomenon. However, these models typically have used four-year college and university environments to build their foundations. Several researchers have attempted to identify predictor variables using…

This guide is addressed to policy officials, program providers, and researchers who are seeking to: (1) identify and implement social programs backed by valid evidence of effectiveness; or (2) sponsor or conduct an evaluation to determine whether a program is effective. The guide provides a brief overview of which studies can produce valid…
