The purpose of this study is to explore the nature of complex adaptive systems (CAS) and network dynamics in international education (IE) programs in a U.S. higher education institution. I analyze the IE programs through a lens of complexity and network theories and ask how measures of engagement in complex networks affect performance in the IE…

Teaching and learning with simulations is widely used in today's classrooms. Therefore, it is important to examine the factors that potentially influence the effectiveness of simulation-based teaching environments. The aim of this research was to compare the effectiveness of teacher-centered and student-centered Physlet-based classes about…

This article reports how simulation strategy applied to improve student's speaking skill. The participants were 36 students of State Junior High School 1 Citeureup, Kranggan, West Java. For about two months they were taught speaking using simulation strategy. The instruments used were speaking test and observation. The data were analyzed using the…

This paper presents a comprehensive review and a specific example implementation of a minimally invasive technique that can be used to make quantitative measurements of a subject's Electro-Dermal Activity (EDA) in educational technology studies. The Q sensor is a low-cost wireless sensor that can be worn on the wrist to measure a subject's…

Previous work covers building a tower from a stack of homogeneous rectangular plates, each with a maximum shift in displacement. We suggest using plates shaped as curvilinear triangles bounded by segments of power-law functions. The masses of the plates and the position of their center of mass are calculated and measured experimentally after…

Measuring voltage-current and voltage-power curves of a photovoltaic module is a nice experiment for high school and undergraduate students. In labs where real sunlight is not available this experiment requires a solar simulator. A prototype of a simulator using LED lamps has been manufactured and tested, and a comparison with classical halogen…

Introduction: Malawi is one of the world's poorest countries with very limited healthcare spending and a lack of post-graduate training for healthcare workers, including in critical illness management. Critical illness simulation courses have been shown to be an effective training tool and form a key part of training for healthcare professionals…

Verbs often participate in more than 1 syntactic structure, but individual verbs can be biased in terms of whether they are used more often with 1 structure or the other. For instance, in a sentence such as "Bop the bunny with the flower," the phrase "with the flower" is more likely to indicate an instrument with which to…

The simulation technology is rapidly expanding and has been used in several nursing programs around the world and in Saudi Arabia too. The aim of this study was to evaluate the effect of using a simulation based scenarios on the pediatric nursing students' students' knowledge, self-efficacy, satisfaction, and confidence. This study used Bandura's…

This paper presents an example of an approach to teaching financial theory at the college and post-graduate levels that I call "teaching backwards". In the more traditional approach, instructors begin by explaining financial theory, then proceed to give examples of the way this theory can be applied to a business problem, structuring…

Recent studies have documented frequency effects for word n-grams, independently of word unigram frequency. Further studies have revealed constructional prototype effects, both at the word level as well as for phrases. The present speech production study investigates the time course of these effects for the production of prepositional phrases in…

A simulation study is presented to evaluate and compare three methods to estimate the variance of the estimates of the parameters d and "C" of the signal detection theory (SDT). Several methods have been proposed to calculate the variance of their estimators, "d'" and "c." Those methods have been mostly assessed by…

Purpose: The purpose of this article is to assess speech processing for listeners with simulated age-related hearing loss (ARHL) and to investigate whether the observed performance can be replicated using an automatic speech recognition (ASR) system. The long-term goal of this research is to develop a system that will assist…

Recent improvements in three-dimensional (3D) virtual modeling software allows anatomists to generate high-resolution, visually appealing, colored, anatomical 3D models from computed tomography (CT) images. In this study, high-resolution CT images of a cadaver were used to develop clinically relevant anatomic models including facial skull, nasal…

This article provides a brief introduction to the Rasch model. Motivation for using Rasch analyses is provided. Important Rasch model concepts and key aspects of result interpretation are introduced, with major points reinforced using a simulation demonstration. Concrete guidelines are provided regarding sample size and the evaluation of items.
