Systematic reviews (SRs) of preclinical studies are marked with poor methodological quality. In vitro studies lack assessment tools to improve the quality of preclinical research. This methodological study aimed to identify, collect, and analyze SRs based on cell culture studies to highlight the current appraisal tools utilized to support the…

Human ratings are ubiquitous in creativity research. Yet, the process of rating responses to creativity tasks -- typically several hundred or thousands of responses, per rater -- is often time-consuming and expensive. Planned missing data designs, where raters only rate a subset of the total number of responses, have been recently proposed as one…

The definition of what constitutes a conflict, in terms of both time and events, has been consistently debated in the historical study of social phenomena. What has become increasingly clear, however, is that the methods used to define it are generally biased as they are highly dependent on the perceptions of the researchers who establish them.…

Positive teacher-student relationships are critical for motivation in secondary school yet are conceptualized and measured inconsistently in motivation research. Motivation studies that draw on relational theories typically treat teacher-student relationships as a multidimensional construct, comprising positive (e.g., closeness) and negative…

Physical activity (PA) promotion is an ideal intervention target for public health because it has the potential to help individuals feel better, sleep better, and perform daily tasks more easily, in addition to providing disease prevention benefits. There is strong evidence that individual-level theory-based behavioral interventions are effective…

This dissertation explores conceptual and methodological issues related to measuring implementation in quantitative educational research. Implementation, defined as the enactment of interventions in educational contexts, plays a pivotal role in understanding how programs operate and affect student outcomes. Despite its importance, there is…

For attaining success in writing, motivation is essential. Crucially, instruction is dependent on knowing the student's capabilities and inner drives. To date, research on writing has yet to establish a consistent framework for assessing writing motivation, and often fails to acknowledge students' self-reports, rather favoring evaluations of…

Introduction: Echolalia, the repetition of others' speech, is a common observation in autistic people. Research has established that echolalia is functional and meaningful for many; however, some clinicians and researchers continue to characterise it as pathological and in need of reduction. The aim of this systematic review was to understand the…

Research Findings: Prosocial behavior in early childhood can be assessed by various informants and methodologies, but the information each provides may differ in meaningful ways. The present study measured and compared young children's (N = 486; age: M = 48.51 months, SD = 8.22) prosocial behavior based on parent reports, teacher reports, and…

Manipulation checks are an essential component of quality experimental design in motor learning. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework, this methodological systematic review examined the utilization of manipulation checks in focus of attention research. Seventy-eight protocols from four…

This paper presents a systematic literature review characterizing the methodological properties of usability studies conducted on educational and learning technologies in the past 20 years. PRISMA guidelines were followed to identify, select, and review relevant research and report results. Our rigorous review focused on (1) categories of…

Implementation analyses conducted as part of impact studies can help educators know whether a tested intervention is likely to be a good fit for their own settings. This guide can help researchers design and conduct these kinds of analyses. The guide provides steps and recommendations about ways to specify implementation research questions, assess…

Exploratory factor analysis is a statistical method commonly used in psychological research to investigate latent variables and to develop questionnaires. Although such self-report questionnaires are prone to missing values, there is not much literature on this topic with regard to exploratory factor analysis--and especially the process of factor…

Measuring the similarity of stimuli is of great interest to a variety of social scientists. Spatial arrangement by dragging and dropping "more similar" targets closer together on the computer screen is a precise and efficient method to measure stimulus similarity. We present Qualtrics-spatial arrangement method (Q-SpAM), a feature-rich…

In mixed methods reviewing, data from quantitative and qualitative studies are combined at the review level. One possible way to combine findings of quantitative and qualitative studies is to quantitize qualitative findings prior to their incorporation in a quantitative review. There are only a few examples of the quantification of qualitative…
