This study explores the effects of ignoring item interaction on item parameter estimation and the efficiency of using the local dependence index Q[subscript 3] and the SAS NLMIXED procedure to detect item interaction under the three-parameter logistic model and the generalized partial credit model. Through simulations, it was found that ignoring…

Short term synaptic plasticity is a phenomenon which is commonly found in the central nervous system. It could contribute to functions of signal processing namely, temporal integration and coincidence detection by modulating the input synaptic strength. This dissertation has two parts. First, we study the effects of short term synaptic plasticity…

For the past few years, virtual environments (VEs) have gained broad attention from both scholarly and practitioner communities. However, in spite of intense and widespread efforts, most VE-related research has focused on the technical aspects of applications, and the necessary theoretical framework to assess the quality of interfaces and designs…

Radical behaviorism considers private events to be a part of ongoing observable behavior and to share the properties of public events. Although private events cannot be measured directly, their roles in overt action can be inferred from mathematical models that relate private responses to external stimuli and reinforcers according to the same…

Analogies are an integral feature of scientific theories, like evolution. They are developed to support explanations, proposed on the basis of evidence collected from experimental studies, field studies, and other observational studies. They map a known source or process to an unknown or target with the goal of helping educators understand the…

Structural equation models are widely appreciated in behavioral, social, and psychological research to model relations between latent constructs and manifest variables, and to control for measurement errors. Most applications of structural equation models are based on fully observed data that are independently distributed. However, hierarchical…

Integrity[TM], an online application for testing both the statistical integrity of the test and the academic integrity of the examinees, was evaluated for this review. Program features and the program output are described. An overview of the statistics in Integrity[TM] is provided, and the application is illustrated with a small simulation study.…

This essay investigates performance events that feature actual refugees, asylum seekers and immigrants, but in instances where presence and embodiment are mediated and made ambiguous. My focus is a fashion show by Catalan designer Antonio Miro, who uses refugees from Senegal as models, and Christoph Schlingensief's public art project…

Structure-Behavior-Function (SBF) thinking considers the different levels of a system in terms of structures, behaviors, and functions, and how these are interconnected (Goel et al. 1996). This article presents an example of helping middle school students use SBF thinking to learn about ecosystems using an aquarium. Students can use an aquarium as…

This article reports MyCaseSpace, a Web-based program used to present clinical cases to students in health-related professions to test their critical thinking skills. The creator of MyCaseSpace, David Segal, an assistant professor in the College of Health and Public Affairs at the University of Central Florida, has created various characters to…

This study examines how conversing with passengers in a vehicle differs from conversing on a cell phone while driving. We compared how well drivers were able to deal with the demands of driving when conversing on a cell phone, conversing with a passenger, and when driving without any distraction. In the conversation conditions, participants were…

Parliamentary procedure is an integral part of the business of many recreation organizations, but students often perceive it to be difficult and irrelevant to their professional preparation. The activity uses the creation of a cookie recipe to practice the basic meeting business functions in parliamentary procedure. The cookie meeting is an active…

Virtual worlds enable students to learn through seeing, knowing, and doing within visually rich and mentally engaging spaces. Rather than reading about events, students become part of the events through the adoption of a pre-set persona. Along with visual feedback that guides the players' activities and the development of visual skills, visual…

In this study, prospective science teachers' misconceptions about the seasons and the phases of the Moon were determined, and then the effects of 3D computer modelling on their conceptual changes were investigated. The topics were covered in two classes with a total of 76 students using a predict-observe-explain strategy supported by 3D computer…

Optimization of a chromatographic separation within the time constraints of a laboratory session is practically impossible. However, by employing a HPLC simulator, experiments can be designed that allow students to develop an appreciation of the complexities involved in optimization procedures. In the present exercise, a HPLC simulator from "JCE…
