A model graduate training curriculum that emphasizes the counselor's role in assisting clients in the effective use of computer-assisted career guidance (CACG) systems is described in this article. This 4-module graduate training program emphasizes client readiness and exploration using CACG systems, skill building and simulation exercises, and…

Older and younger adults' abilities to use context information rapidly during ambiguity resolution were investigated. In Experiments 1 and 2, younger and older adults heard ambiguous words (e.g., fires) in sentences where the preceding context supported either the less frequent or more frequent meaning of the word. Both age groups showed good…

Students analyze a contemporary geopolitical event from a comprehensive geographic perspective using role play simulation, discussion, and decision-making. The three-day activity provides teachers with a realistic, ready-made classroom lesson that combines powerful conceptual learning with drama and surprise. The task of the teacher is to…

The increased availability of computational modeling software has created opportunities for students to engage in scientific inquiry through constructing computer-based models of scientific phenomena. However, despite the growing trend of integrating technology into science curricula, educators need to understand what aspects of these technologies…

Despite a century of research, the mechanisms underlying short-term or working memory for serial order remain uncertain. Recent theoretical models have converged on a particular account, based on transient associations between independent item and context representations. In the present article, the authors present an alternative model, according…

In this paper it is presented a virtual organizational environment, conceived with the integration of three computer programs: a manufacturing simulation package, an automation of businesses processes (workflows), and business intelligence (Balanced Scorecard) software. It was created as a supporting tool for teaching IE, its purpose is to give…

The article presents an approach to emergency response training that combines simulation of hazardous environmental factors with extensive registration of the activities in a training scenario. Simulation enhances realism by exposing the trainees to representations of hazards without putting them at risk. Registration generates data that describe…

The new representations enabled by the educational computer game the "Juggler" can place vectors in a central role both for controlling and measuring the behaviours of objects in a virtual environment simulating motion in three-dimensional spaces. The mathematical meanings constructed by 13 year-old students in relation to vectors as…

Previous research has shown that computer-based tasks can motivate people with autism and encourage learning. As a computer-based medium, Virtual Environments (VEs) offer a potentially useful tool for social skills training for people with autistic spectrum disorders (ASDs). However, there are some concerns over whether people with ASDs can…

Many students enter mathematics courses with a poor attitude toward mathematics (Gal & Ginsburg, 1994), making attitude as important a consideration as achievement in mathematics (Cognition and Technology Group at Vanderbilt (CTGV), 1992; Marsh, Cairns, Relich, Barnes, & Debus, 1984; Sedighian & Sedighian, 1996). Pedagogical agents are often…

Energy production is an essential part of American society and the economy. In the best tradition of community colleges, Bismarck State College (BSC) in North Dakota has responded to the specialized training needs of industry for over 25 years by forming various collaborative efforts with the energy industry. This article presents an example of…

One principle of applied research is to design intervention programs targeted to teach useful skills to the participants (Baer, Wolf, & Risley, 1968), while structuring the program to promote generalization of the skills to the natural environment (Stokes & Baer, 1977). Proficiency in community skills (e.g., community navigation and…

There have been few attempts to introduce frameworks that can help support tutors evaluate educational games and simulations that can be most effective in their particular learning context and subject area. The lack of a dedicated framework has produced a significant impediment for the uptake of games and simulations particularly in formal…

Finite mixture models are well known to have poorly behaved likelihood functions featuring singularities and multiple optima. Growth mixture models may suffer from fewer of these problems, potentially benefiting from the structure imposed on the estimated class means and covariances by the specified growth model. As demonstrated here, however,…

Eight independent variables (differential item functioning [DIF] detection method, purification procedure, item response model, mean latent trait difference between groups, test length, DIF pattern, magnitude of DIF, and percentage of DIF items) were manipulated, and two dependent variables (Type I error and power) were assessed through…
