Haptic-Based Virtual Reality Dental Simulator as an Educational Tool

This chapter describes the haptic dental simulator developed at the University of Illinois at Chicago. It explores its use and advantages as an educational tool in dentistry and examines the structure of the simulator, its hardware and software components, the simulator’s functionality, reality assessment, and the users’ experiences with this technology. The authors hope that the dental haptic simulation program should provide significant benefits over traditional dental training techniques. It should facilitate students’ development of necessary tactile skills, provide unlimited practice time and require less student/instructor interaction while helping students learn basic clinical skills more quickly and effectively.

Criterion Time

A debate is emerging regarding the efficacy of proficiency based versus duration based training of technical skills. It is not clear whether the performance level attained at the end of practice (i.e., proficiency criteria), or the overall amount of practice performed during learning will best predict the retention of a technical clinical skill. The skill learned was the single-handed double square-knot. Forty two trainees learned the skill through video-based instruction and were divided into three groups (14 participants per group) each with a specific criterion time to tie the knot (10, 15, and 20 seconds). Practice continued until participants completed the knot within their criterion time. The total number of trials, and the overall practice time required to obtain each respective criterion were recorded during practice. Participants returned one-week later for a timed retention test consisting of one trial of the knot tying skill with no video instruction. A multiple regression analysis tested whether the amount of practice, the total practice time, or the criterion reached at the end of practice was the best predictor of the time taken to perform the skill during retention. This analysis showed that the number of practice trials was highly correlated with total practice time (r = .82, p = .01), therefore total practice time was withdrawn as a predictor variable from the subsequent analysis. The regression showed that the only significant predictor of retention performance was the criterion reached at the end of practice (p = .03). The number of practice trials was not found to significantly predict the retention performance (p = .87). The results support the notion that proficiency based training results in better retention of a technical clinical skill in comparison to duration based approaches. This provides evidence for the introduction of proficiency based educational approaches in technical skills curricula. Jowett N, LeBlanc V, Xeroulis G, MacRae H, Dubrowski A.

AbstractThe CAVE, a walk-in virtual reality environment typically consisting of 4–6 3 m-by-3 m sides of a room made of rear-projected screens, was first conceived and built in 1991. In the nearly two decades since its conception, the supporting technology has improved so that current CAVEs are much brighter, at much higher resolution, and have dramatically improved graphics performance. However, rear-projection-based CAVEs typically must be housed in a 10 m-by-10 m-by-10 m room (allowing space behind the screen walls for the projectors), which limits their deployment to large spaces. The CAVE of the future will be made of tessellated panel displays, eliminating the projection distance, but the implementation of such displays is challenging. Early multi-tile, panel-based, virtual-reality displays have been designed, prototyped, and built for the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia by researchers at the University of California, San Diego, and the University of Illinois at Chicago. New means of image generation and control are considered key contributions to the future viability of the CAVE as a virtual-reality device.

This article details the process of self-reflection applied to the use of traditional performance indicator questionnaires. The study followed eight speech-language pathology graduate students enrolled in clinical practicum in the university, school, and healthcare settings over a period of two semesters. Results indicated when reflection was focused on students' own clinical skills, modifications to practice were implemented. Results further concluded self-assessment using performance indicators paired with written reflections can be a viable form of instruction in clinical education.

By examining folk music activities connecting students and local musicians during the early 1960s at the University of Illinois at Urbana-Champaign, this article demonstrates how university geographies and musical landscapes influence musical activities in college towns. The geography of the University of Illinois, a rural Midwestern location with a mostly urban, middle-class student population, created an unusual combination of privileged students in a primarily working-class area. This combination of geography and landscape framed interactions between students and local musicians in Urbana-Champaign, stimulating and complicating the traversal of sociocultural differences through traditional music. Members of the University of Illinois Campus Folksong Club considered traditional music as a high cultural form distinct from mass-culture artists, aligning their interests with then-dominant scholarly approaches in folklore and film studies departments. Yet students also interrogated the impropriety of folksong presentation on campus, and community folksingers projected their own discomfort with students’ liberal politics. In hosting concerts by rural musicians such as Frank Proffitt and producing a record of local Urbana-Champaign folksingers called Green Fields of Illinois (1963), the folksong club attempted to suture these differences by highlighting the aesthetic, domestic, historical, and educational aspects of local folk music, while avoiding contemporary socioeconomic, commercial, and political concerns. This depoliticized conception of folk music bridged students and local folksingers, but also represented local music via a nineteenth-century rural landscape that converted contemporaneous lived practice into a temporally distant object of aesthetic study. Students’ study of folk music thus reinforced the power structures of university culture—but engaging local folksinging as an educational subject remained for them the most ethical solution for questioning, and potentially traversing, larger problems of inequality and difference.

The Church

For over two centuries, the College was the characteristic form of higher education in the United States, and the College was closely allied to the church in a predominantly Protestant land. The university became the characteristic form of American higher education starting in the late nineteenth Century, and universities long continued to reflect the nation's Protestant culture. By about 1900, however, Catholics and Jews began to enter universities in increasing numbers. What was the experience of Jewish students in these institutions, and how did authorities respond to their appearance? These questions will be addressed in this article by focusing on the Jewish presence at the University of Illinois in the early twentieth Century. Religion, like a red thread, is interwoven throughout the entire fabric of this story.
