Introduction: This study aimed to develop a cost-effective suturing and knot typing simulator that aligns with the expectations of experts, addressing the need for affordable yet high-quality medical training tools. The focus was on assessing the efficacy of a silicone skin suture task trainer, created through a 3D printed mold, for use in mobile…

This paper presents a concept for designing low-cost therapeutic training with biofeedback and virtual reality. We completed the first evaluation of a prototype--a mobile learning application for relaxation training, primarily for adolescents suffering from tension-type headaches. The system delivers visual experience on a head-mounted display. A…

This article elaborates on how the technical capabilities of virtual reality support the constructivist learning principles. It introduces VRID, a model for instructional design and development that offers explicit guidance on how to produce an educational virtual environment. The define phase of VRID consists of three main tasks: forming a…

The results of computer simulations of each of 17 variations on 4 prototypical desegregation plans applied to the Los Angeles Unified School District (LAUSD) are reported in this document. The prototypes, each representing a category of proposals offered at one point or another during the litigation of the desegregation issues are: (1) an…

This document reports the results of computer simulations of each of 19 variations on 4 prototypical desegregation plans applied to the Los Angeles Unified School District (LAUSD). Each prototype represents one of the following categories of proposals offered during the litigation of the desegregation issue in the California courts: (1) an…
