In particular research domains, the randomized control trial (RCT) is considered to be the only means for obtaining reliable estimates of the true impact of an intervention. However, an RCT design would often not be considered ethical, politically feasible, or appropriate for evaluating the impact of many policy, programme, or structural changes…

A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

We conducted a systematic literature review examining the participant characteristics of studies of students with emotional disturbance (ED) with the purpose of better understanding potential similarities and differences between students with ED in research and the population of students with ED. Results indicate (a) participants with reported…

Introduction: Psychological science is undergoing a period of change and transformation. Statement of the Problem: The crisis in confidence over psychological science has led to an emphasis on larger and larger sample sizes, sustaining an unfortunate neglect of single-subject research designs in undergraduate education. Literature Review: We…

Designed to be used as a primary text in introductory research methods courses, "Music Education Research: An Introduction" aims to orient even the most novice researchers toward basic concepts and methodologies. Offering sustained attention to historical, philosophical, qualitative, quantitative, and action research approaches, the book…

To advance and encourage partnerships between institutions and their greater communities, academic reward structures must be designed in ways that support those who choose to leverage their expertise, resources, and time to engage with community in meaningful and mutually beneficial ways. This study investigates how school- and department-level…

The role of lecturers at the University of Guyana has always included research. However, the productivity of these lecturers has historically been low. This dissertation examines the reasons for low research productivity among lecturers and attempts to understand the underlying concerns. Through a series of action research cycles, the researcher…

The study aimed to conduct a systematic literature review to identify the trends, impacts, and challenges of mobile microlearning (MML) research. Using five academic databases from the fields of social science, engineering, and medical science as search sources, 26 scholarly articles, published between 2015 and 2020, were retrieved. The study…

The increasing volume of large-scale assessment data poses a challenge for testing organizations to manage data and conduct psychometric analysis efficiently. Traditional psychometric software presents barriers, such as a lack of functionality for managing data and conducting various standard psychometric analyses efficiently. These challenges…

Background/Context: Observational studies often employ regression discontinuity (RD) designs and multiple control-group designs to explore the causal quantities of interest. RD designs assess policy and program effectiveness by assigning subjects to treatment based on whether they exceed a pre-defined cutoff. RD designs are classified into two…

Empirical studies often demonstrate multiple causal mechanisms potentially involving simultaneous or causally related mediators. However, researchers often use simple mediation models to understand the processes because they do not or cannot measure other theoretically relevant mediators. In such cases, another potentially relevant but unobserved…

When designing a study for causal mediation analysis, it is crucial to conduct a power analysis to determine the sample size required to detect the causal mediation effects with sufficient power. However, the development of power analysis methods for causal mediation analysis has lagged far behind. To fill the knowledge gap, I proposed a…

The laboratory is a complex environment where the three levels of the chemistry triplet coincide. As the laboratory environment places a large demand on the working memory of students, cognitive load theory can address overload which causes barriers to learning. Breaking down barriers requires iterative phases of analysis/exploration,…

Biology education research provides important guidance for educators aiming to ensure access for disabled students. However, there is still work to be done in developing similar guidelines for research settings. By using critical frameworks that amplify the voices of people facing multiple forms of marginalization, there is potential to transform…

In this article we propose a taxonomy describing various types of literature review or theoretical/conceptual articles. We distinguish each article type based on how well they address the "summary" and "advocacy" arguments inherent in all secondary scholarship. Understanding this taxonomy of review/theory scholarship is…
