SCC Lab member and CSE PhD student Katie Kuksenok and SCC Lab director Cecilia Aragon were co-authors on a recent article accepted to the Journal of Surgical Research. The article titled “Crowd-Sourced Assessment of Technical Skills (C-SATS): A Novel Method to Evaluate Surgical Performance” marks the first use of crowdsourcing for surgical skills assessment. The article was co-authored by Carolyn Chen, Lee White, Timothy Kowalewski, Rajesh Aggarwal, Chris Lintott, Bryan Comstock, Katie Kuksenok, Cecilia Aragon, Daniel Holst, and Thomas Lendvay.

The article explores the effectiveness of large crowds sampled from two on-line crowdsourcing venues, Amazon.com’s Mechanical Turk and Facebook, testing the hypothesis that crowdsourcing of technical skills using validated surgical assessment tools is equivalent to assessment by experienced surgeon educators. Their results show that not only could crowds, presumably unfamiliar with surgical education, rate a common robotic surgery suturing task equivalent to experienced surgeons’ ratings, but that the crowds could also be honed to identify crowd workers who demonstrated markers of critical thinking making the workers more accurate. While this research finding does not presume that such a rating can assess surgical judgement, they note that this observation is not unlike being able to identify good from bad athletic performances in a sport one may have no ability to play.

This research represents a departure from conventional wisdom and practice in the area of procedural skills education. CSATS may provide a potential opportunity to disseminate basic technical skills assessment rapidly and globally while preserving educator resources ‘on the ground’ for refined, tailored advanced technical skills curricula to accelerate individual learning curves.

SCC lab member and HCDE PhD student Daniel Perry has received two best paper awards at the Extreme Science and Engineering (XSEDE) 2013 Conference in San Diego. Perry received Best Student Paper and Best Training, Education, & Outreach Paper Awards for the paper, “Human Centered Game Design for Bioinformatics and Cyberinfrastructure Learning,” which he presented at XSEDE on July 24.

The paper was co-authored by HCDE Professor and SCC lab director Cecilia Aragon, Stephanie Cruz (PhD student in Medical Anthropology), Mette Peters (Sage Bionetworks), and Jeanne Chowning (Northwest Association for Biomedical Research). It provides a human centered game design methodology for science educators and science game designers, as well as design implications for integrating collaborative learning experiences into the usage of large-scale shared computing resources and services. In the talk, Perry detailed their ongoing design process with high school students, undergraduate and graduate students, scientists, and educators in the development of the bioinformatics and cyberinfrastructure learning game Max5.

A paper titled “Perceptions of Interfaces for Eye Movement Biometrics” by lab member Michael Brooks, lab director Cecilia Aragon, and Oleg Komogortsev (Texas State University San Marcos) has been accepted for publication at the 2013 International Conference on Biometrics. The conference will take place June 4-7 in Madrid, Spain. Through user studies of emerging technology for biometric identification via eye movement patterns, the paper argues for the increased use of human centered design practices in biometric systems research and development.

Lab member Daniel Perry presented at the 2013 iConference (February 12 – 15) in Fort Worth, Texas. His presentation was titled “VizDeck: Streamlining exploratory visual analytics of scientific data,” and described the design and evaluation of VizDeck, a web-based visual analytics tool that automatically recommends a set of appropriate visualizations based on the statistical properties of the data and adopts a card game metaphor to present the results to the user. The talk was well received, and one of three visualization long papers presented this year. Daniel commented that “the iConference is just getting better and better each year. I was really impressed with some of the social media and other visualization presentations this year.”
