Over the last decade, there has been much excitement about the use of optogenetic tools to test whether specific cells, regions, and projection pathways are necessary or sufficient for initiating, sustaining, or altering behavior. However, the use of such tools can result in side effects that can complicate experimental design or interpretation.…

This article describes the analysis of regression-discontinuity designs (RDDs) using the R packages rdd, rdrobust, and rddtools. We discuss similarities and differences between these packages and provide directions on how to use them effectively. We use real data from the Carolina Abecedarian Project to show how an analysis of an RDD can be…

Not long ago, "brand" was an unmentionable word in the higher education landscape--one that came with suspicious connotations of consumer packaged goods and retail. Today, however, there is increasingly broad acceptance that a higher education institution's (HEI's) brand is critical to attracting and retaining the best students and…

The regression discontinuity (RD) design is a popular quasi-experimental design for causal inference and policy evaluation. The most common inference approaches in RD designs employ "flexible" parametric and nonparametric local polynomial methods, which rely on extrapolation and large-sample approximations of conditional expectations…

By distinguishing between a survey and--a newly introduced term--a "probe," we recast the relationship between qualitative and quantitative approaches to social science. The difference turns on the "uniformity" of the phenomenon being examined. Uniformity is a fundamental idea underlying all scientific research but is rarely…

The purpose of this research study is to examine the master's theses and dissertations carried out about history education research in Turkey in terms of certain variables. The study is a qualitative research and it used documentary research design as a research method. The population of the research study is the master's theses and dissertations…

The authors conducted a content analysis on quantitative studies published in "The Journal for Specialists in Group Work" ("JSGW") between 2012 and 2015. This brief report provides a general overview of the current practices of quantitative group research in counseling. The following study characteristics are reported and…

Four education scholars extend the methodological space inspired by Jackson and Mazzei's "Thinking with Theory" through focusing on research design. The notion of de/sign is presented and employed to counter prescriptive method/ology that often sutures over pedagogical possibilities in research and educational settings. Key…

Single-case designs provide an established technology for evaluating the effects of academic interventions. Researchers interested in studying the long-term effects of reading interventions often use curriculum-based measures of reading (CBM-R) as they possess many of the desirable characteristics for use in a time-series design. The reliability…

This article addresses a gap in methodological writing, concerning typical practice in designing qualitative inquiry, especially in research on educational leadership. The article focuses on how qualitative research designs are actually developed and explores implications for scholars' work, especially for new scholars and for methods teachers.…

There is an expectation that all researchers will act ethically and responsibly in the conduct of research involving humans and animals. While research ethics is mentioned in quality indicators and codes of responsible researcher conduct, it appears to have little profile in doctoral assessment. There seems to be an implicit assumption that…

The purpose of this dissertation was to examine the successful implementation of social media strategies in multiple organizations. Examining the factors an organization used to implement social media can provide the understanding of the benefits and risks associated with this technology. Some businesses are considered successful using social…

The What Works Clearinghouse (WWC) systematic review process is the basis of many of its products, enabling the WWC to use consistent, objective, and transparent standards and procedures in its reviews, while also ensuring comprehensive coverage of the relevant literature. The WWC systematic review process consists of five steps: (1) Developing…

The purpose of the research study was to measure any change among undergraduate students in their attitudes and beliefs about death, dying, and bereavement after taking a class specifically focused on this topic. Human services professionals frequently work with clients trying to cope with issues related to death, dying, and bereavement, and their…

As part of my PgCert in Higher Education Practice, I undertook a learning and teaching research project into the effect of small group mathematics tutorials on student confidence and academic performance. I chose this project because it related directly to my practice as a higher education lecturer: I regularly supported first year animal science…
