Background: Because meta-analyses are increasingly prevalent and cited in the medical literature, it is important that tools are available to assess their methodological quality. When performing an empirical study of the quality of published meta-analyses, we found that existing tools did not place a strong emphasis on statistical and…

Collaboration between researchers and educators in conducting intervention research is increasingly common, as such collaboration is assumed to benefit educational practice. Alternatively, in this study, we explore the consequences of such collaboration on research quality. Based on our analysis of a year-long collaboration in formative…

Lillard et al. (2013) have done a thorough review of published pretend play research from the past 50 plus years. However, they did not thoroughly address the reasons why this body of research has such flaws as well as the contradictory or minimal findings that call into question strongly held views and published assertions regarding the…

Single case designs (SCDs) are short time series that assess intervention effects by measuring units repeatedly over time both in the presence and absence of treatment. For a variety of reasons, interest in the statistical analysis and meta-analysis of these designs has been growing in recent years. This paper proposes modeling SCD data with…

This paper and the accompanying tool are intended to complement existing supports for conducting power analysis tools by offering a tool based on the framework of Minimum Detectable Effect Sizes (MDES) formulae that can be used in determining sample size requirements and in estimating minimum detectable effect sizes for a range of individual- and…

The 4-H youth development organization is a complex public--private partnership between the U.S. Department of Agriculture's National Institute of Food and Agriculture, the nation's Cooperative Extension system and National 4-H Council, a private, nonprofit partner. The current article is focused on a partnership approach to the…

Instructors frequently utilize breaching experiments in an attempt to "bring sociology to life." However, an uncritical embrace of breaching experiments obscures the complexity of their possible effects on participants and subjects. These experiments have real potential to inflict deleterious consequences on individuals and groups.…

This article describes Sondra Perl's retrospective review of the composing processes of unskilled college writers and whether her assumptions and values in the designing of research projects have changed over her long teaching career. She uses her college dissertation "Five Writers Writing" as the basis to reflect on the authors and…

Planned missing designs are becoming increasingly popular, but because there is no consensus on how to implement them in longitudinal research, we simulated longitudinal data to distinguish between strategies of assigning items to forms and of assigning forms to participants across measurement occasions. Using relative efficiency as the criterion,…

Due to an increasing interest in the use of single-subject experimental designs (SSEDs), appropriate techniques are needed to analyze this type of data. The purpose of this paper proposal is to present four studies (Beretvas, Hembry, Van den Noortgate, & Ferron, 2013; Bunuan, Hembry & Beretvas, 2013; Moeyaert, Ugille, Ferron, Beretvas,…

The Montessori method is an attractive alternative to traditional education for many parents in the United States of America and abroad (Lillard & Else-Quest, 2006). There are between 4,000 and 5,000 private Montessori programs in the United States, and thousands more internationally (American Montessori Society, 2016; Lillard &…

This paper examines the status of the implementation of continuous assessment (CA) in Mettu University. A random stratified sampling method was used to select 309 students and 29 instructors and purposive method used to select quality assurance and faculty Deans. Questionnaires, focus group discussion, interview and documents were used for data…

The purpose of this article is to explore the application of qualitative research to establishing a more complete understanding of relational processes inherent in school psychology practice. We identify the building blocks of rigorous qualitative research design through a conceptual overview of qualitative paradigms, methodologies, methods (i.e.,…

This study applied a content analysis methodology in two ways to evaluate first-year students' research topics: a rubric to examine proposed topics in terms of scope, development, and the "researchability" of the topic, as well as textual analysis, using ATLAS.ti, to provide an overview of the types of subjects students select for a…

One obstacle to understanding abstract concepts such as the "control of variables" strategy (CVS) is the tendency for learners to focus on surface rather than deep features in instructional materials. However, in tasks such as learning CVS, these same surface features may also support understanding, provided learners realize the…
