This article generalizes linear path analysis (PA) and simultaneous equations models (SiEM) to deal with mixed responses of different types in a recursive or triangular system. An efficient instrumental variable (IV) method for estimating the structural coefficients of a 2-equation partially recursive generalized path analysis (GPA) model and…

This paper describes a neural model of speech acquisition and production that accounts for a wide range of acoustic, kinematic, and neuroimaging data concerning the control of speech movements. The model is a neural network whose components correspond to regions of the cerebral cortex and cerebellum, including premotor, motor, auditory, and…

A socially optimized learning approach, which integrates diverse theoretical perspectives, places men who have sex with men (MSM) in an interactive virtual environment designed to simulate the emotional, interpersonal, and contextual narrative of an actual sexual encounter while challenging and changing MSM's more automatic patterns of risky…

Skill and risk taking are argued to be independent and to require different remedial programs. However, it is possible to contend that skill-based training could be associated with an increase, a decrease, or no change in risk-taking behavior. In 3 experiments, the authors examined the influence of a skill-based training program (hazard…

Business simulations provide a teaching method that typically yields (1) more hands-on experience, (2) a higher level of excitement, (3) a higher noise level (and yet a lower incidence of problems), and (4) more commitment than traditional methods of teaching (McLure 1997, 3). Business simulations are experiential learning opportunities that have…

When most academic technologists tackle computing, their time is occupied by laptops and servers--relatively small-scale stuff. A couple of blades here, a couple of blades there. Generally, even for network managers, the processing power rarely stacks up to anything awe-inspiring. Sometimes, however, computing can be bigger and broader than many…

This article explores the uses of a simulation model (the two bucket story)--implemented by a stand-alone computer program, or an Excel workbook (both on the web)--that can be used for deriving bootstrap confidence intervals, and simulating various probability distributions. The strengths of the model are its generality, the fact that it provides…

Anatomy curriculum has changed dramatically around the world since the 1960s. These changes include the reduction of course hours, the abandonment of cadaver dissection, the use of problem-based learning, application of other teaching modalities such as prosected specimens, models, radiographic images, computer simulations, and the introduction of…

In this article, the authors describe an e-mail-based simulation that helps students experience the fast-paced, complex world of the middle manager. In this electronic in-basket exercise, students assume the role of a district manager in a doughnut company as they respond to a rapid series of high- and low-priority e-mails ostensibly sent from…

A structure for learning the connections among standard deviations, z-scores, and normal distributions is presented. The components of this structure are classified into intuitive or previously learned conceptual knowledge, computational knowledge, and formalized conceptual knowledge. (Contains 1 figure.)

Videotape and computer simulation are sophisticated technological applications that have great potential to enhance group work practice. Computer simulation has been harnessed for entertainment and business purposes but has not been adequately utilized for teaching social skills. This article describes strategies for integrating video and computer…

The existing maximum likelihood theory and its computer software in structural equation modeling are established on the basis of linear relationships among latent variables with fully observed data. However, in social and behavioral sciences, nonlinear relationships among the latent variables are important for establishing more meaningful models…

Using task-based exercises that required web searches and online activities, this course introduced non-traditional students to the sights and sounds of the German culture and language and simultaneously to computer technology. Through partner work that required negotiation of the net as well as of the language, these adult beginning German…

This paper describes the use of interactive, Physlet[R]-based curricular material designed to help students learn concepts of thermodynamics with a particular focus on the use of kinetic theory models. These exercises help students visualize ideal gas particle dynamics and engine cycles, make concrete connections between mechanics and…

This study investigates use of computer simulation for teaching ATM use to adults with intellectual disabilities. ATM-SIM is a computer-based trainer used for teaching individuals with intellectual disabilities how to use an automated teller machine (ATM) to access their personal bank accounts. In the pilot evaluation, a prototype system was…
