The logarithmic transformation is a commonly applied procedure in regression analysis when two or more variables have a nonlinear relationship. When the response variable is logarithmically transformed, confidence intervals for conditional means and predictions may actually be wider than their counterparts obtained from the model with the original…

This article talks about fulldome video, a new technology which has been adopted fairly extensively by the larger, well-funded planetariums. Fulldome video, also called immersive projection, can help teach subjects ranging from geology to history to chemistry. The rapidly advancing progress of projection technology has provided high-resolution…

Teaching and learning are highly social activities. Seminal psychologists such as Vygotsky, Piaget, and Bandura have theorized that social interaction is a key mechanism in the process of learning and development. In particular, the benefits of peer interaction for learning and motivation in classrooms have been broadly demonstrated through…

This snapshot introduces a computer-based representation and activity that enables students to simultaneously "see" the combinatorial space of a stochastic device (e.g., dice, spinner, coins) and its outcome distribution. The author argues that the "ambiguous" representation fosters student insight into probability. [Snapshots are subject to peer…

One of the simulation engines of an open-source program called the Molecular Workbench, which can simulate thermodynamics of chemical reactions, is described. This type of real-time, interactive simulation and visualization of chemical reactions at the atomic scale could help students understand the connections between chemical reaction equations…

Speech-language pathologists (SLPs) who work with adults with cognitive-linguistic impairments, including aphasia, have long needed an assessment tool that predicts ability to function in the real world. In this article, it is argued that virtual reality (VR)-supported approaches can address this need. Using models of disability such as the…

Virtual reality (VR) describes a set of technologies that allow users to explore and experience 3-dimensional computer-generated "worlds" or "environments." These virtual environments can contain representations of real or imaginary objects on a small or large scale (from modeling of molecular structures to buildings, streets, and scenery of a…

A three-dimensional pendulum, modelled after the Laser Interferometer Gravitational-Wave Observatory's suspended optics, was constructed to investigate the pendulum's dynamics due to suspension point motion. In particular, we were interested in studying the pendular-pitch energy coupling. Determination of the pendular's Q value (the quality factor…

This report examined whether Virtual Reality Exposure Therapy (VRET) could be used in the treatment of posttraumatic stress disorder (PTSD) symptoms in the aftermath of a serious motor vehicle accident. Six individuals reporting either full or severe subsyndromal PTSD completed 10 sessions of VRET, which was conducted using software designed to…

With the rapid development of the information communication and technology (ICT) infrastructure in the Caribbean, there is an increasing demand for skilled software developers to meet the ICT needs of the region. Consequently, the web-based applications course offered at the University of the West Indies, has been redeveloped. One major part of…

New capabilities in "TinkerPlots 2.0" supported the conceptual development of fifth- and sixth-grade students as they pursued several weeks of instruction that emphasized data modeling. The instruction highlighted links between data analysis, chance, and modeling in the context of describing and explaining the distributions of measures that result…

This paper focuses on the different ways in which students in lower secondary school (14-16 year olds) experience compound random events, presented to them in the form of combined junctions. A carefully designed ICT environment was developed enabling the students to interact with different representations of such structures. Data for the analysis…

Proficiency in English is a prerequisite for students to bag a place in the on/off campus interviews. Irrespective of the profession, vocation and background the students have to hone their LSRW skills in English. Selection procedures like group discussion and video conferencing are hurdles to students who lack language proficiency in English. All…

The Horizon Report series is the product of the New Media Consortium's Horizon Project, an ongoing research project that seeks to identify and describe emerging technologies likely to have a large impact on teaching, learning, research, or creative expression within education around the globe. This volume, the "Horizon Report: 2009 K-12…

Purpose: The purpose of this paper is to propose that the measurement of salivary amylase activity is an effective index to evaluate the stress of a ship navigator for safe navigation training and education. Design/methodology/approach: Evaluation comes from the simulator and actual on-board experiments. The subjects are real captains who have…
