"Moneyball"…

This article analyzes the research of 205 doctoral dissertations and masters' theses in the domain of blended learning. A summary of trends regarding the growth and context of blended learning research is presented. Methodological trends are described in terms of qualitative, inferential statistics, descriptive statistics, and combined approaches…

There is extensive research on the benefits of making data-informed decisions, but research also contains evidence many educators incorrectly interpret student data. Meanwhile, the types of detailed labeling on over-the-counter medication have been shown to improve use of "non"-medication products, as well. However, data systems most…

In the last couple of years, a new aspect of online social networking has emerged, in which the strength of social network connections is based not on social ties but mutually shared interests. This dissertation studies these "curation-based" online social networks (CBN) and their suitability for the diffusion of electronic word-of-mouth…

Learning analytics can promote pedagogically informed use of learner data, which can steer the progress of technology mediated learning across several learning contexts. This paper presents the application of analytics to a mobile learning solution and demonstrates how a pedagogical sense was inferred from the data. Further, this inference was…

The current study evaluated the performance of traditional versus modern MDTs in the estimation of fixed-effects and variance components for data missing at the second level of an hierarchical linear model (HLM) model across 24 different study conditions. Variables manipulated in the analysis included, (a) number of Level-2 variables with missing…

A post-WWII assignment from the U.S. Navy analyzing data from a test of a harbor mine-detecting algorithm leads to a new construction of the symmedian point.

Model building or model selection with linear mixed models (LMMs) is complicated by the presence of both fixed effects and random effects. The fixed effects structure and random effects structure are codependent, so selection of one influences the other. Most presentations of LMM in psychology and education are based on a multilevel or…

The ever-increasing production of digital textual data in a wide variety of forms presents both opportunities and challenges to researchers. The opportunities derive from the rich availability of secondary data with which to work. The challenges are the familiar ones of lack of time and resources to undertake the analysis. The qualitative…

E. Abel and M. Kruger (2005) reported that the median life expectancy of Major League Baseball players after election to the Baseball Hall of Fame is 5 years shorter than that of players of the same age who are not elected to the Hall of Fame.

Though created to draw awareness to the unique needs of a particular group of students, the LTEL label has acquired…

Researchers use many different metrics for evaluation of performance of student models. The aim of this paper is to provide an overview of commonly used metrics, to discuss properties, advantages, and disadvantages of different metrics, to summarize current practice in educational data mining, and to provide guidance for evaluation of student…

This narrative inquiry seeks to advance the field of educational leadership preparation by exploring ways to interrupt personal, interpersonal, and institutional racism through the senses--ways in which people perceive their experiences and relation to others. Findings suggest that participants engage in actions aligned with revelations from their…
