In this paper, we describe a pedagogical approach to elastic body movement based on measurements of the contact times between a metallic rod and small bodies colliding with it and on modelling of the experimental results by using a microcomputer-based laboratory and simulation tools. The experiments and modelling activities have been built in the…

An $11 million executive-training course for principals, modeled after best practices used in the corporate, medical, engineering, and military worlds, is starting to gain traction among states. Developed by the National Institute for School Leadership, or NISL, a for-profit company based in Washington, the program is now used widely in…

Consider test data, a specified set of dichotomous skills measured by the test, and an IRT cognitive diagnosis model (ICDM). Statistical estimation of the data set using the ICDM can provide examinee estimates of mastery for these skills, referred to generally as attributes. With such detailed information about each examinee, future instruction…

This article explores the benefits of the Internet to enhance history instruction for all learners. The authors describe a Web-based learning environment, the Virtual History Museum (VHM), that helps teachers create motivating, inquiry-based history units. VHM also allows teachers to build supports for learners with disabilities or other learning…

Taxometric procedures provide an empirical means of determining which psychiatric disorders are typologically distinct from normal behavioral functioning. Although most disorders reflect extremes along continuously distributed behavioral traits, identifying those that are discrete has important implications for accurate diagnosis, effective…

As computer-mediated communication becomes increasingly prevalent in the workplace, students need to apply effective writing principles to today's technologies. Email, in particular, requires interns and new hires to manage incoming messages, use an appropriate tone, and craft clear, concise messages. In addition, with instant messaging (IM)…

Students with disabilities are now more than ever being included in physical education classes. However, most physical educators feel they have not received adequate preparation in their undergraduate programs regarding teaching students with disabilities. There are many factors that go into providing a positive inclusive setting, such as using…

Electronic game technologies can prepare novice learners for future learning of complex concepts. This paper describes the underlying instructional design, learning science, cognitive science, and game theory. A structural, or syntactic mapping (structure mapping), approach to game design can produce a game world relationally isomorphic to a…

Similar to many property tax relief programs, New York State's School Tax Relief (STAR) program has been shown to exacerbate school resource inequities across urban, suburban, and rural schools. STAR's inherent conflict with the wealth equalization policies of New York State's school finance system are highlighted in a manner that effectively…

The National Institute of School Leadership's (NISL's) Executive Development Program (EDP) was established to provide professional development to school leaders to drive their schools to high performance. The program emphasizes the role of principals as strategic thinkers, instructional leaders, and creators of a just, fair, and caring culture in…

Purpose: The purpose of this paper is to report on a study into how a three-dimensional (3D) virtual world (Second Life) can facilitate socialisation and team working among students working on a team project at a distance. This models the situation in many commercial sectors where work is increasingly being conducted across time zones and between…

Eight teams of elementary and middle school teachers developed pilot online courses for the North Carolina Virtual Public School (NCVPS) in the USA. A qualitative case study with focus groups and a follow-up survey helped to identify common needs of these non-traditional course designers during course development efforts. Findings suggest virtual…

In this paper the online construction of disability is investigated and the implications for educators working in virtual worlds are considered. Based on the analysis of data collected through interviews with deaf residents of "Second Life", it is argued that research into online identity, disability and education needs to allow room for…

Research addressing the effectiveness of feedback for learning has focused on many dimensions of feedback, including the timing (Kulik & Kulik, 1988), type (Mory, 2004), and amount of available information (Dempsey et. al, 1993). Much of the feedback research in education has tacitly assumed that the available information is perceived, and any…

Alternative approaches to evaluating critical thinking skills are needed, as pencil and paper assessments may not accurately predict simulated or actual clinical performance. To ensure patient safety, it is imperative to determine how to best promote and measure critical thinking skills. Few studies have examined how these skills are related to…
