It is difficult for consumers to access the evidence base for prevention programs to determine which models or practices have the strongest empirical support for improving youth social, emotional, and behavioral (SEB) outcomes within their specific service contexts. Researchers can address this evidence-to-practice gap through innovations in…

Purpose: To assess strengths and weaknesses of the reading level (RL) match approach and its potential to generate insights regarding the cognitive foundations of reading ability and disability. Method: We applied RL-match design to a sample of 2nd-6th graders reading a consistent orthography, Russian, using an "extreme phenotype"…

This article explores the viability of online crowdsourcing for creating matched-comparison groups. This exploratory study compares survey results from a randomized control group to survey results from a matched-comparison group created from Amazon.com's MTurk crowdsourcing service to determine their comparability. Study findings indicate…

In this paper, we examine the validity and precision of two nonexperimental study designs (NXDs) that can be used in educational evaluation: the comparative interrupted time series (CITS) design and the difference-in-difference (DD) design. In a CITS design, program impacts are evaluated by looking at whether the treatment group deviates from its…

There are several goals guiding this study. First, the authors use an experimental design to examine the causal effects of giving children 10 self-selected books over two summers. Second, they examine whether treatment effects are moderated by children's family income (i.e., eligibility for free- and reduced-price lunch). As a result, they examine…

Background: Recruiting schools into a matched-pair randomized control trial (MP-RCT) to evaluate the efficacy of a school-level prevention program presents challenges for researchers. We considered which of 2 procedures would be most effective for recruiting schools into the study and assigning them to conditions. In 1 procedure (recruit and…

This pilot study proposes a set of analytical steps for comparing schools that participate in the National Science Foundation's Math and Science Partnership (MSP) Program and their nonparticipating peers in the same state. This pilot is part of a larger effort to evaluate the MSP Program's role in student achievement, with two companion analyses.…

This article discusses the difficulties in conducting intervention research or evaluating intervention programs in a school setting. In particular, the problems associated with randomization and obtaining control groups are examined. The use of quasi-experimental designs, specifically a paired comparison design using the individual as his or her…

Purpose: Where the auditory saltation illusion has been used as a measure of auditory temporal processing (ATP) in dyslexia, conflicting results have been apparent (cf. R. Hari & P. Kiesila, 1996; M. Kronbichler, F. Hutzler, & H. Wimmer, 2002). This study sought to re-examine these findings by investigating whether dyslexia is characterized by…

The author sought to identify differences in kinship social support, self-esteem, and coping responses between African American college students who identify themselves as adult children of alcoholics (ACOAs) and adult children of nonalcoholics (non-ACOAs) at 2 separate universities. The results indicate that there were no differences in levels of…

This study examined the impact of the 2+2 Alternative Teacher Performance Appraisal System that has been implemented in Shanxi province in China. A mixed research design was used to evaluate the program. Six high schools and a total of 78 teachers (13 teachers in each school) in Shanxi province were selected. Three of the schools participated in…

Purpose: The purpose of this study was to investigate chorus reading's (CR's) effect on speech effort during oral reading by adult stuttering speakers and control participants. The effect of a speech effort measurement highlighting strategy was also investigated. Method: Twelve persistent stuttering (PS) adults and 12 normally fluent control…

Despite its apparent simplicity, random assignment is an abstract concept for many students. This article describes a classroom demonstration that uses a standard deck of playing cards. In small groups, students randomly assign playing cards (i.e., participants) to 2 treatment groups. Following randomization, students compare the relative…

This paper evaluates the effectiveness of a student controlled computer program for high school mathematics based on instruction principles derived from Schoenfeld's theory of problem solving. The computer program allows students to choose problems and to make use of hints during different episodes of solving problems. Crucial episodes are:…
