This study used the Delphi technique with 31 seasoned leadership educators who, over the course of two rounds, were tasked to categorize the level of complexity of 60 leadership competencies. What resulted was a five-tier taxonomy based on the level of complexity of each of the 60 competencies assessed. The taxonomy also includes four categorical…

This paper questions the idea that there are two opposing paradigms of educational research, often called positivist versus interpretivist. It argues that the 'paradigm' term has been used to avoid philosophical discussions about the nature of educational research. This has been done by understanding 'paradigms' to reflect metaphysical positions…

A distinctive feature of contemporary professional, vocational and continuing education is the prevalence of the 'competency' approach. So-called competency-based education or training (CBE/T) can be adopted as a basis for programs of learning, frameworks for development within occupations, or for national systems of vocational education. Its…

To design and improve instruction in mathematical proof, mathematics educators require an adequate definition of proof that is faithful to mathematical practice and relevant to pedagogical situations. In both mathematics education and the philosophy of mathematics, mathematical proof is typically defined as a type of justification that satisfies a…

Purpose: This study aims to critically examine talent management practices and strategies from ethical and responsible management perspectives. Design/methodology/approach: It achieves its aim through conceptual analysis by theorising through the lenses of talent philosophies, the organisational justice theory, the stakeholder theory and extant…

A key component of research on human sentence processing is to characterize the processing difficulty associated with the comprehension of words in context. Models that explain and predict this difficulty can be broadly divided into two kinds, expectation-based and memory-based. In this work, we present a new model of incremental sentence…

This study models how new ideas, practices, or diseases spread within and between communities, the diffusion of innovations or contagion. Several factors affect diffusion such as the characteristics of the initial adopters, the seeds; the structure of the network over which diffusion occurs; and the shape of the threshold distribution, which is…

New items are often evaluated prior to their operational use to obtain item response theory (IRT) item parameter estimates for quality control purposes. Fixed parameter calibration is one linking method that is widely used to estimate parameters for new items and place them on the desired scale. This article provides detailed descriptions of two…

Background: The cross-lagged panel (regression) model (CLPM) is the usual framework of choice to test the longitudinal reciprocal effects between self-concept and achievement. Criticisms of the CLPM are that causal paths are over-estimated as they fail to discriminate between- and within-person variation. The random-intercept cross-lagged panel…

The purpose of this study is to evaluate whether a recently developed semiordered model can be used to explore the functioning of neutral response options in rating scale data. Huggins-Manley, Algina, and Zhou developed a class of unidimensional models for semiordered data within scale items (i.e., items with both ordered response categories and…

Management of the Ghana Technology University College took the decision to adopt blended learning (BL) for teaching and learning because of its effectiveness as a learning approach. However, academicians are apprehensive about teaching in blended learning environment. A major study to understand the factors influencing faculty to adopt blended…

This chapter examines the impact and success of mid-level business and finance staff at private colleges or universities, using an adaptation of Bronfenbrenner's multilevel social integration model. This chapter also highlights the voices of mid-level business and finance staff and describes the experiences, successes, and challenges they have…

In this theoretical paper we compare the Piagetian perspective on knowledge construction to mathematical model construction, with the aim to understand how mathematical modeling enables learning of mathematics and learning of science, as is often claimed. We do this by examining data through two lenses: (1) examining the role of cognitive conflict…

During the past decade, cognitive diagnostic models (CDMs) have become prevalent in providing diagnostic information for learning. Cognitive diagnostic models have generally focused on single cross-sectional time points. However, longitudinal assessments have been commonly used in education to assess students' learning progress as well as…

The aim of this article is twofold. First, it provides a general overview of reading compre­hension by outlining classic models of single-text comprehension and more recent models of multiple-text comprehension and sourcing during reading comprehension. Second, the article highlights important sources of individual differences in reading…
