In contrast to randomized experiments, the estimation of unbiased treatment effects from observational data requires an analysis that conditions on all confounding covariates. Conditioning on covariates can be done via standard parametric regression techniques or nonparametric matching like propensity score (PS) matching. The regression or…

Due to an increasing interest in the use of single-subject experimental designs (SSEDs), appropriate techniques are needed to analyze this type of data. The purpose of this paper proposal is to present four studies (Beretvas, Hembry, Van den Noortgate, & Ferron, 2013; Bunuan, Hembry & Beretvas, 2013; Moeyaert, Ugille, Ferron, Beretvas,…

Forensic nursing is an emerging nursing specialty recognized by the American Nursing Association. However, nurses often do not have the basic knowledge or practical competence to provide the appropriate level of forensic care. The purpose of this study was to determine if differences in knowledge or practical competence existed between students…

In this paper, the authors examine the state of the art in augmented reality (AR) for mobile learning. Previous work in the field of mobile learning has included AR as a component of a wider toolkit but little has been done to discuss the phenomenon in detail or to examine in a balanced fashion its potential for learning, identifying both positive…

Abstraction is a key concept in CS, one of the most fundamental ideas underlying CS and its practice. However, teaching this soft concept to novices is a very difficult task, as discussed by many CSE experts. This paper discusses this issue, and suggests a general framework for teaching abstraction in CS to novices, a framework that would fit into…

This paper explains the design of a graphics-based virtual environment for instructing computer hardware concepts to students, especially those at the beginner level. Photorealistic visualizations and simulations are designed and programmed with interactive features allowing students to practice, explore, and test themselves on computer hardware…

Understanding spoken words involves a rapid mapping from speech to conceptual representations. One distributed feature-based conceptual account assumes that the statistical characteristics of concepts' features--the number of concepts they occur in ("distinctiveness/sharedness") and likelihood of co-occurrence ("correlational…

Poor student engagement with academic readings has been frequently reported in college classrooms. As an effort to improve college students' reading engagement, researchers have developed a virtual environment in which students take on the role of tutor and teach a virtual tutee, the virtual tutee system (VTS). This research examined the…

American students graduate from college with tens of thousands of dollars in debt, leading to substantial repayment burdens and potentially inefficient shifts in spending patterns and career choices. A political trend towards austerity coupled with the rising student debt make the effective allocation of federal higher education resources and…

As state boards of education and other state policymakers consider the future of schools, sorting fad technology from technology that accelerates learning is key. Virtual reality (VR) is one such technology with promise that seems unlikely to fizzle. Hailed as potentially transformative for education and still in the early stages of application,…

Students frequently expressed difficulty in understanding the molecular mechanisms involved in chromosomal recombination. Therefore, we explored alternative methods for presenting the two concepts of the double-strand break model: Holliday junction and heteroduplex formation, and Holliday junction resolution. In addition to a lecture and…

Components of complex systems apply across multiple subject areas, and teaching these components may help students build unifying conceptual links. Students, however, often have difficulty learning these components, and limited research exists to understand what types of interventions may best help improve understanding. We investigated 32 high…

The study examined the effect of simulation technique and lecture method on students' academic performance in Mafoni Day Secondary School, Maiduguri. The study used both simulation technique and lecture methods of teaching at the basic level of education in the teaching/learning environment. The study aimed at determining the best predictor among…

As literature has reported, it is usual that university students in statistics courses, and even statistics teachers, interpret the confidence level associated with a confidence interval as the probability that the parameter value will be between the lower and upper interval limits. To confront this misconception, class activities have been…

The use of virtual simulations in Legal Education as a method for learning is relatively rare despite much theoretical support that exists for the benefits in learning. There is also some apprehension on the use of technology in legal education. Both of these are likely due to the lack of solid evaluations concerning the overall impact in…
