Collapsing categories is a commonly used data reduction technique; however, to date there do not exist principled methods to determine whether collapsing categories is appropriate in practice. With ordinal responses under the partial credit model, when collapsing categories, the true model for the collapsed data is no longer a partial credit…

The aim of this study was to create a model which describes the main elements for improving schools with digital technology and helps to reveal differences between schools and identify their best practices and challenges. The innovative digital school model (IDI school) offers a framework for research but also a research-based model for schools to…

Educational leadership is facing a need for change; this change requires innovative approaches such as Universal Design for Learning (UDL) to transform teacher practice. Principled modelling by these leaders is integral to sustained change. In addition, to initiate this change, traditional practices such as group work can be used with a UDL focus…

Technology Education was introduced and rolled out in South African schools in 1998. It has been twenty years since its implementation, yet it is being confused with other traditional subjects. Therefore, even though it is expected that Technology Education should be known for what it is exactly, it is still misunderstood, misconceived and…

This article explores a conceptual relationship between learner choice and mathematical sense-making. It argues that when learners can exercise choice in their mathematical activities, mathematical sense-making can be enhanced. The literature around mathematical modelling suggests a link between sense-making and learner choice. A three-tiered…

Within caring science, the concept of caring leadership is well established. The aim of this study is to introduce Bondas's theory of caritative leadership into education. The theory of caritative leadership is a theory of caring leadership with the 'caritas' thought of human love and mercy at its core. The article considers a hypothetical testing…

The authors argue that nonfiction reading and writing instruction in K-12 settings must include authentic opportunities for students to seek information online. To that end, the authors provide two frameworks for thinking about information acquisition in the 21st century. The first, the intentional and incidental information continuum, describes…

Science learning for undergraduate students requires grasping a great number of theoretical concepts in a rather short time. In our experience, this is especially difficult when students are required to simultaneously use abstract concepts, mathematical reasoning, and graphical analysis, such as occurs when learning about RC circuits. We present a…

The community of inquiry (COI) model identifies elements which are fundamental to a successful online learning experience, namely, teaching presence, cognitive presence, and social presence. The model has received empirical support as a useful framework for understanding the online learning experience. A limitation of the model is its…

We offer a brief history of the study of excellence in college and university teaching. We review major examinations of teaching excellence and summarize key characteristics of model teachers.

Attribute structure is an explicit way of presenting the relationship between attributes in diagnostic measurement. The specification of attribute structures directly affects the classification accuracy resulted from psychometric modeling. This study provides a conceptual framework for understanding misspecifications of attribute structures. Under…

An important aspect of qualitative research is reaching saturation--loosely, a point at which observing more data will not lead to discovery of more information related to the research questions. However, there has been no validated means of objectively establishing saturation. This article proposes a novel quantitative approach to measuring…

Discussions of the core in sociology have focused on faculty members' perspectives regarding what should be taught in introductory sociology courses. Because the development of curricula is and should be a social process, we argue that students' perceptions of learning outcomes also should be considered when curricula are developed. This study…

Youth with disabilities are dramatically overrepresented in the juvenile justice system. These individuals have poorer outcomes compared with their nondisabled peers regarding school graduation, employment, and recidivism. This discussion article explores issues related to transition and outlines research-based practices aimed at increasing…

This study presents a model for the early identification of students who are likely to fail in an academic course. To enhance predictive accuracy, sentiment analysis is used to identify affective information from text-based self-evaluated comments written by students. Experimental results demonstrated that adding extracted sentiment information…
