Children's fuzziness leads to increased variance in the data, data loss, and high dropout rates in developmental studies. This study investigated the importance of 20 factors on the person (child, caregiver, experimenter) and situation (task, method, time, and date) level for the data quality as indicated via the number of valid trials in 11…

Preregistration involves researchers publicly registering key study elements before conducting a study to increase the transparency of research and limit the use and impact of questionable research practices. To support special education researchers' engagement with preregistrations, in this article we provide an overview of preregistration and…

Single-case comparative studies could help identify efficient instructional procedures for individuals with disabilities. However, previous literature reported inconsistent efficiency results if multiple comparisons were conducted, indicating that within-participant replication was uncommon. In this review, we examined single-case comparative…

Background: In Malaysia, the mortality from melioidosis infection was reported to be higher than in other infectious diseases. The research on melioidosis is still limited in Malaysia but slightly increasing. Objectives: The objective of the study was to give an overview of the study designs, statistical methods, and comparison of research in…

Decomposing variables into between and within components are often required in multilevel analysis. This method of decomposition should not ignore possible unreliability of an observed group mean (i.e., arithmetic mean) that is due to small cluster sizes and can lead to substantially biased estimates. Adjustment procedures that allow unbiased…

Questionnaires inquiring about psychopathology symptoms often produce data with excess zeros or the equivalent (e.g., none, never, and not at all). This type of zero inflation is especially common in nonclinical samples in which many people do not exhibit psychopathology, and if unaccounted for, can result in biased parameter estimates when…

Background: The concept of engagement is a multidimensional construct that has long been used by researchers as a means of explaining student behaviour in classrooms and schools. However, the research using this construct within physical education has been particularly uneven. Purpose: The goal of this paper was to examine the application of the…

Over the past few decades, e-Learning has been implemented to account for the challenges of twenty-first-century learning propelled by the spread of the internet and the use of internet-based technologies. These dynamic changes informed research interests in the academia, from awareness and adoption studies, researchers are now focused on…

Purpose: A literature research conducted in education and agricultural education journals published during a period of 10 years revealed that 98% of the studies used parametric analyses. In general, model assumptions were not tested, and statistical criteria were not followed to apply the parametric approach. The objective of this paper is to…

The purpose of this article is to examine the influence of the school organizational climate on teacher enthusiasm. A sample of 600 teachers was drawn using a multi-stage random sampling method. The study variables were assessed using two main instruments: the organizational climate scale and teacher's enthusiasm scale. A two-staged structural…

Identifying impediments to learning can help both instructors and students. In this study students (N = 222) from across the nation listed concepts from research methods they found the most challenging--"potholes" or impediments to learning, and also rated the difficulty of various concepts from the class. We also measured student…

A nuanced understanding of disparities impacting racialized people with intellectual and developmental disabilities (IDD) requires scholars employ research methods that make visible the structural factors that influence outcomes. Following the work of Tukufu Zuberi and Eduardo Bonilla-Silva, we explore race-based methodological considerations for…

Whether selection processes contribute to group-level disparities or merely reflect pre-existing inequalities is an important societal question. In the context of observational data, researchers, concerned about omitted-variable bias, assess selection-contributing inequality via a kitchen-sink approach, comparing selection outcomes of…

This study examined the relationship between the subjective negative feeling states that undergraduate students felt about a research methods course and of their course performance. A total of 106 undergraduates were surveyed about their subjective feeling states at both the beginning and the end of the term. These feeling variables were…

This study aims to identify correlates of attitudes toward evidence-based treatment (EBT) and the evidence-based practice (EBP) process among master's of social work (MSW) students who intend to be direct service practitioners. Participating MSW students (N =165) were recruited from an advanced research methods course at one university in the…
