The performance evaluation of e-learning in medical education has been the subject of much research lately. Researchers are yet to achieve a consensus on the definition of performance or the suitable constructs, metrics, models, and methods to help understand student performance. Through a systematic review, this study put forward a working…

Background: Since the COVID-19 pandemic, American students have demonstrated substantial losses in achievement (Amplify, 2021; Domingue et al., 2021; Dorn et al., 2020; Storey & Zhang, 2023), while chronic absenteeism doubled after the pandemic, with the largest increase among low-income students (Chang et al., 2022; Dorn et al., 2021). Among…

This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

Background: Using meta-analytic review techniques, this study synthesized the results of 79 unpublished studies about the nature of transformational school leadership (TSL) and its impact on the school organization, teachers, and students. This corpus of research associates TSL with 11 specific leadership practices. These practices, as a whole,…

Video modeling interventions involve a child watching videotapes of positive examples of adults, peers, or him- or herself engaging in a behavior that is being taught. The purpose of this review was to examine empirical studies in which video modeling interventions were applied to individuals with autism. Nineteen studies published between 1985…

Several researchers have employed milieu therapy to address the communication needs of children with autism spectrum disorder (ASD). Thus, the purpose of this review is to examine milieu therapy, particularly, the environments and individuals involved in the training and the effectiveness of milieu therapy with children who have a diagnosis of ASD…

The mathematical representation of E. Brunswik's (1952) lens model has been used extensively to study human judgment and provides a unique opportunity to conduct a meta-analysis of studies that covers roughly 5 decades. Specifically, the authors analyzed statistics of the "lens model equation" (L. R. Tucker, 1964) associated with 249 different…

A sequential design utilizing identical samples was used to classify mixed methods studies via a two-dimensional model, wherein sampling designs were grouped according to the time orientation of each study's components and the relationship of the qualitative and quantitative samples. A quantitative analysis of 121 studies representing nine fields…

The major purpose of instructional science is to prescribe optimal methods to bring about desired learning, and the purposes of this paper are twofold: (1) to encourage individuals in the discipline to think in terms of contributing to a collegial, or even competitive, building of a common knowledge base in instructional science, and (2) to…

Empirical literature on two types of hearings, and their applicability in evaluating educational programs, is reviewed. An introduction describes the use and nature of hearings and distinguishes adversary hearings, in which two parties argue opposing sides of an issue, from committee hearings, in which a variety of positions are presented to a…

Describes the development, characteristics, and validation of a model, derived from sources in the literature, for the inservice professional development of educational administrators. The model has three crucial stages: planning, implementing, and evaluating. Each of these stages contains four steps: analysing, developing, operating, and…

This paper examines representative research in information science and compares its designs to an abstract ideal of the experimental research design. Threats to validity of conclusions are highlighted, including history, maturation, testing, instrumentation, statistical regression, selection biases, experimental mortality, and selection-maturation…

This overview of nonexperimental causal research methods focuses on latent variable structural equation modeling using the LISREL computer program. An extended example in special education is used to present LISREL as an extension of structural equations analysis (path analysis) and as a method of reducing the effects of error in research.…

Using the viewpoint of semiotics, this paper "re-reads" Karl Marx's labor theory of value and suggests a "triple triangle" model for commodity production and shows how this model could be a model for semiosis in general. The paper argues that there are three advantages to considering homogeneity of the sign production and the…

Structural models and classes of variables used in parent/child research are identified, and their implications are briefly discussed. The five types of research models appraised are noninteractive, unidirectional, bidirectional, family network, and sociopolitical. It is asserted that, taken together, the typology of models provides a system by…
