This work provides a characterization of the learning of graph theory through the lens of the van Hiele model. For this purpose, we perform a theoretical analysis structured through the processes of reasoning that students activate when solving graph theory problems: recognition, use and formulation of definitions, classification, and proof. We…

Academic resilience refers to students' capacity to perform highly despite a disadvantaged background. Although most studies using international large-scale assessment (ILSA) data defined academic resilience with two criteria, student background and achievement, their conceptualizations and operationalizations varied substantially. In a systematic…

McGrath presents a prototyping proposal to better classify character education programs. He proposes 7 key elements that can facilitate identifying more and less typical programs. This proposal appears to be a very good start for improving the organization of the character education field and facilitating research. This commentary highlights 4…

Problem Statement: The concepts of innovation and entrepreneurship must be understood and adopted to ensure such transformation in the university after "Entrepreneurial and Innovative University Index" publication. The basic problem of this research is an analysis of how entrepreneurs define the concepts of innovation and…

This paper reviews current proposals concerning the definition of dyslexia and contrasts it with reading comprehension impairment. We then discuss methods for early identification and review evidence that teacher assessments and ratings may be valid screening tools. Finally, we argue that interventions should be theoretically motivated and…

Cambridge Assessment has more than 20 years experience in assessing Critical Thinking (CT) in a number of diverse tests and qualifications, unrivalled by any other body within the UK. In recent years, a number of research activities have been carried out in order to support these assessments, with a focus on the validity of measurement. This paper…

Lissitz and Samuelsen (2007) have proposed an operational definition of "validity" that shifts many of the questions traditionally considered under validity to a separate category associated with the utility of test use. Operational definitions support inferences about how well people perform some kind of task or how they respond to some kind of…

Provides an overview of the use of models in instructional design. Highlights include a definition of the term model; types of models, including conceptual, procedural, mathematical, and prescriptive; procedures for model development; classification of models in the literature; and alternative techniques for model validation. (Contains 38…

The definition of mental disorder in the third edition of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-III-R) explains that a disorder is harmful and represents a dysfunction, but it fails to capture the idea of dysfunction. Ideas for increasing the conceptual validity of the definition are presented. (SLD)

A definition and typology of peer assessment between students in higher education is proposed, and the theoretical underpinnings of the method are discussed, based on a review of both process and outcome studies. These studies suggest that peer assessment is of adequate reliability and validity in many situations. (SLD)

This paper reviews research on the classification of students with learning disability (LD). It first examines the evolution of LD definitions and the evidence for three components of LD classification: discrepancy, heterogeneity, and exclusion. It suggests that classification hypotheses involving discrepancy and exclusion have weak validity and…

Provides a framework for understanding the concept of validity and how it applies to simulation research. Extant tests of validity are discussed in terms of this framework, and a general schema for testing validity is proposed. (MBR)

This article describes the two basic versions of the responsiveness-to-intervention (RTI) approach for identifying learning disabilities, the problem solving model and the standard-protocol approach. It reviews evidence on effectiveness and feasibility and concludes that more needs to be understood before RTI may be viewed as a valid…

This paper argues that because estimates of the number of people with developmental dyslexia range from 3% to 20% of the population, it is imperative that educators be knowledgeable about dyslexia, including being up-to-date on the neuroanatomical dyslexia research. It then reviews neuroanatomical research, including findings from seminal research…

Three studies investigated children's responsiveness to general education reading instruction as an indicator of need for more intensive interventions and found that the response-to-instruction model tested was valid. Results indicated that children at-risk (n=47) who received specially designed general education instruction had better outcomes…
