The research presented in this Case Study examines adjunct faculty satisfaction at an online public institution of higher education. Specifically, I analyzed student-, individual-, and institution-related factors of faculty satisfaction based on a previously constructed survey instrument found in the literature. While carrying out the research,…

Over the past 15 years, qualitative case study research has become more prominent in agricultural education. The first case study research appeared in the Journal of Agricultural Education (JAE) in 1997. To date, 33 qualitative case study research articles have been published in JAE. Additionally, case study research has become highly visible at…

Currently the design standards for single case experimental designs (SCEDs) are based on validity considerations as prescribed by the What Works Clearinghouse. However, there is a need for design considerations such as power based on statistical analyses. We compute and derive power using computations for (AB)[superscript k] designs with multiple…

The exposure of scientific scandals and the increase of dubious research practices have generated a stream of studies on Questionable Research Practices (QRPs), such as failure to acknowledge co-authors, selective presentation of findings, or removal of data not supporting desired outcomes. In contrast to high-profile fraud cases, QRPs can be…

In this digital ITEMS module, Dr. Jeffrey Harring and Ms. Tessa Johnson introduce the linear mixed effects (LME) model as a flexible general framework for simultaneously modeling continuous repeated measures data with a scientifically defensible function that adequately summarizes both individual change as well as the average response. The module…

In mixed methods approaches, statistical models are used to identify "nested" cases for intensive, small-n investigation for a range of purposes, including notably the examination of causal mechanisms. This article shows that under a commonsense interpretation of causal effects, large-n models allow no reliable conclusions about effect…

This paper proposes a new application of Stochastic Frontier Analysis (SFA) for estimating the student performance gap and how this can be used to assess changes of teaching quality at the individual unit-of-study level (module-level). Although there have been other examples in the literature that assess 'efficiency' in student outcomes, this is…

Single-case experimental designs (SCEDs) are a useful tool for evaluating the effects of interventions at an individual level and can play an important role in the development and validation of evidence-based practices. Historically, researchers relied on visual analysis of SCED data and eschewed statistical approaches. Although researchers…

Many statistical methods (estimators) are available for estimating the consensus value (or average effect) and heterogeneity variance in interlaboratory studies or meta-analyses. These estimators are all valid because they are developed from or supported by certain statistical principles. However, no estimator can be perfect and must have error or…

This study investigated the power of two-level hierarchical linear modeling (HLM) to explain variability in intervention effectiveness between participants in context of single-case experimental design (SCED) research. HLM is a flexible technique that allows the inclusion of participant characteristics (e.g., age, gender, and disability types) as…

Purpose: This article uses an illustrative case example to discuss a means of producing a holistic profile of Internet use for individuals with aphasia. Methods: The authors used the International Classification of Functioning, Disability, and Health as a framework to select novel and existing assessments to explore the Internet use and skills of…

Self-regulation is a well-known construct in educational and psychological research, as it is often related to academic success and well-being. Drawing from criticisms of a lack of context applied to the investigation of this construct, the current study examined the multi-dimensional role of social support (teachers, parents, peers) and coping…

Being bullied at school is strongly related to psychological health complaints at the same time point. Studies have also found long-term associations, but few have combined a prospective design with children's own reports on bullying, and conducted gender-specific analyses. The present study assesses health consequences in young adulthood of…

This study aimed to explore commonalities among discrimination, stereotyping, and peer-related social experiences of children of immigrants, and to see if these experiences might relate to children's school-based well-being. Two age-based cohorts of 294 children and their immigrant parents from Portugal, the Dominican Republic, and Cambodia were…

This case study contributes to the higher education curriculum development literature by showing how a faculty-led short-term study abroad experience can become the catalyst for student research and offer students an international perspective. The authors analyze students' reflections and provide data collected over the years of taking…
