The attitude of teachers towards inclusive education is a key issue for the success of inclusive education. Many studies have been designed to assess teachers' attitudes, but none have looked at the bias caused by teachers' non-response to questionnaires on their attitudes. Non-response biases are difficult to identify because it is impossible to…

Group design studies in education include groups such as students, teachers, caregivers, schools, or districts assigned to conditions, typically treatment and control, to compare outcomes between the groups. Although the use of group designs in education has become more frequent and robust, the use of group designs in rural education lags far…

Scientific misconduct, leading to the retraction of publications, presents a significant challenge to the progress of societies as it undermines both the scientific reputation and material resources of countries. This study adopts bibliometric analysis and scientometrics approach to examine the characteristics of retracted publications in the…

The following article addresses a conundrum: What if child assent in research were a fully informed, standalone process that empowered all children to discuss meaningfully, negotiate, and decide how and what the research experience would look like? Past research and practices suggest that child assent, when children (youths to 17-year-olds who…

The recent commentary by Beaujean and Farmer (2020) on the original paper by Dixon et al. (2019) serves a cautionary tale of selective p-values, the law of small N sizes, and the type-II error. We believe these authors have crafted a somewhat questionable argument in which only 57% of the original Dixon et al. data were re-analyzed, based on a…

In recent decades, there has been an explosion of research into the crossmodal influence of olfactory cues on multisensory person perception. Numerous peer-reviewed studies have documented that a variety of olfactory stimuli, from ambient malodours through to fine fragrances, and even a range of chemosensory body odours can influence everything…

Address-based sampling (ABS) refers to the use a list of addresses derived from the U.S. Postal Service's Computerized Delivery Sequence File as a sampling frame. While most residential addresses are included on an ABS frame, it still suffers from undercoverage. Undercoverage is problematic only if the uncovered units have different attributes…

The population discrepancy between unstandardized and standardized reliability of homogeneous multicomponent measuring instruments is examined. Within a latent variable modeling framework, it is shown that the standardized reliability coefficient for unidimensional scales can be markedly higher than the corresponding unstandardized reliability…

Collaborative projects designed to generate research evidence involve knowledge exchange (KE) which hinges on the expectations and practices within the collaborating organisations. Existing literature about academic-police collaborations, and why they break down, has largely focused on different knowledge agendas, research timeframes and…

Asymmetric Likert-type items in research studies can present several challenges in data analysis, particularly concerning missing data. These items are often characterized by a skewed scaling, where either there is no neutral response option or an unequal number of possible positive and negative responses. The use of conventional techniques, such…

Research is about an individual's intellectual acumen and rationality, and inter-researcher collaboration capability magnifies the outcomes. Despite common belief, there exist fundamental asymmetries in the goals, orientations and expectations among the research collaborators. Seldom studied in-depth and empirically validated, the challenges and…

The transgender community is rich with wisdom about how to live authentically, embrace duality, and embody intersecting identities, but our stories have been widely missing from or misrepresented in research. "Insider" community-engaged research offers a framework for boundary-spanning researchers to blend their "insider" and…

Research designs that include planned missing data are gaining popularity in applied education research. These methods have traditionally relied on introducing missingness into data collections using the missing completely at random (MCAR) mechanism. This study assesses whether planned missingness can also be implemented when data are instead…

Simple matrix sampling planned missing (SMS PD) design, introduce missing data patterns that lead to covariances between variables that are not jointly observed, and create difficulties for analyses other than mean and variance estimations. Based on prior research, we adopted a new multigroup confirmatory factor analysis (CFA) approach to handle…

In the field of disparities research, there has been growing interest in developing a counterfactual-based decomposition analysis to identify underlying mediating mechanisms that help reduce disparities in populations. Despite rapid development in the area, most prior studies have been limited to regression-based methods, undermining the…
