Notwithstanding its crucial role in facilitating desired outcomes of schooling, educational psychology researchers have recognized the conceptual haziness of student engagement as a multidimensional construct. With the main purpose of refining its conceptual definition, this paper aims to attain the following four goals. First, we seek to…

In the present article, we introduce a generalization of the spherical inversion. In particular, we define an inversion with respect to an ellipsoid, and prove several properties of this new transformation. The inversion in an ellipsoid is the generalization of the elliptic inversion to the three-dimensional space. We also study the inverse images…

This chapter looks at how various scholars have attempted to structure the "infinite field" by defining the appropriate theory and methods. These efforts have centered on a conception of what it would take to make comparative education a "science," and how one could achieve "objective knowledge." While these concerns…

The present paper offers a definition of peer assessment and then reviews the major syntheses on its effectiveness. However, the main part of this paper is preoccupied with how to do PA successfully. A typology of 44 elements explains the differences between the many types of peer assessment. Then a theoretical model outlines some of the processes…

This paper critically explores how survey and routinely collected data could aid in assessing the generalisability of public health evidence. We propose developing approaches that could be employed in understanding the relevance of public health evidence, and investigate ways of producing meta-analytic estimates tailored to reflect local…

In the last few decades universities became service providers. In this case an open question is raised: what is the student role then? This article aims to enlighten the discourse of the student role. At first glance, a student is supposed to be just a passive service consumer--a client. Yet recent service management literature proposes that…

The concept of item discrimination is generalized to the case in which more than one ability is required to determine the correct response to an item, using the conceptual framework of item response theory and the definition of multidimensional item difficulty previously developed by M. Reckase (1985). (SLD)

A 5-second constant time delay procedure was used to teach 10 word definitions to 3 fifth grade students with mild learning handicaps. All students learned the definitions in 8 to 9 sessions with students maintaining correct responding at 6, 10, and 14 weeks after training. Generalization was also observed. (Author/DB)

The advantages and disadvantages of wider or narrower definitions of "pidginization" and "pidgin" are reviewed to determine the differences between pidgins and naturalistically learned second languages (L2s). It is argued that a wider definition is preferred because it avoids problematic counterexamples and captures…

Definitions and short explanations of key concepts in the field of instructional evaluation are presented. Evaluation is defined as the process of determining the value of programs, projects, materials, and personnel. It is distinguished from research in that the aims of research are less time- and situation-specific, attempting to uncover…
