Previous simulation studies of randomization tests applied in single-case educational intervention research contexts have typically focused on A-to-B phase changes in means/levels. In the present simulation study, we report the results of two multiple-baseline investigations, one targeting between-phase changes in slopes/trends and the other…

The central roles of science in the field of remedial and special education are to (a) identify basic laws of nature and (b) apply those laws in the design of practices that achieve socially valued outcomes. The scientific process is designed to allow demonstration of specific (typically positive) outcomes, and to assist in the attribution of…

We appreciate the thoughtful reactions of our colleagues to the "no prescriptives, please" proposal of Robinson et al. (2013), as well as the opportunity to respond to them. For the most part, our colleagues seem to agree that a problem exists in terms of unwarranted recommendations for practice appearing too often in educational…

To counteract what we see as a growing research-reporting concern, we propose the following editorial-policy change regarding the content of primary research articles in educational research journals: Contributors should restrict their discussion and conclusions to their data and not offer recommendations for educational practice nor speculate…

Two previous studies examining 5 empirical educational psychology research journals (Hsieh et al., 2005; Robinson, Levin, Thomas, Pituch, & Vaughn, 2007) found that in the 21-year period from 1983 to 2004, there was a decrease in intervention and randomized experimental research, whereas in the 10-year period from 1994 to 2004, there was an…

The purpose of the present study was to investigate the statistical properties of two extensions of the Levin-Wampold (1999) single-case simultaneous start-point model's comparative effectiveness randomization test. The two extensions were (a) adapting the test to situations where there are more than two different intervention conditions and (b)…

Robinson, Levin, Thomas, Pituch, and Vaughn (2007) examined 74 articles reporting nonintervention studies (i.e., studies with no researcher-manipulated variables) that appeared in 5 educational journals in 1994. Of these articles, 22 contained prescriptive statements (e.g., if teachers or students did X, then student outcome Y would result). In…

In recent years, single-case designs have increasingly been used to establish an empirical basis for evidence-based interventions and techniques in a variety of disciplines, including psychology and education. Although traditional single-case designs have typically not met the criteria for a randomized controlled trial relative to conventional…

Reviews educationally relevant mnemonic strategy research, awarding "grades" to various mnemonic strategies and curricular applications. Mnemonic materials designed for factual content and mnemonic applications for educationally handicapped students are awarded A's, whereas teachers, mnemonic strategy critics, and mnemonic strategy…

In this article, the authors examined intervention studies that appeared in four educational psychology journals (Cognition & Instruction, Contemporary Educational Psychology, Journal of Educational Psychology, Journal of Experimental Education) and the American Educational Research Journal (AERJ) in 1983 and from 1995 to 2004. The majority of…

This article focuses on the early research domains investigated by Michael Pressley, along with the integrations and initiatives that were inspired by them. These research domains include verbal and imagery elaboration memory strategies, and developmental aspects of them; interrogative elaboration; pictorial strategies for language and literacy…

Elaboration in learning involves meaning-enhancing additions, constructions, or generations that improve one's memory for what is being learned. Recent examples of applications of elaboration theory include efforts in the areas of meta-cognitive components of learning strategies, mnemonics, and text-processing strategies. (TJH)

In the studies reported here, repetition of an orally presented story did help first grade children remember the information, but pictures were even more effective in facilitating recall of information. (Author)

The promise of time-series designs for educational research and evaluation is reviewed. Ten time-series designs are presented and discussed in the context of threats to internal and external validity. The advantages and disadvantages of various visual and statistical data-analysis techniques are presented. A bibliography is appended. (Author/RD)

Outlines concerns that must be addressed by those who advocate replacing statistical hypothesis-testing with alternative data-analysis strategies. Suggests that commonly recommended alternatives are not perfect and that various hypothesis-testing modifications can be implemented to make the process and its conclusions more credible. Hypothesis…
