When I read this question I ask myself: Do they mean PECE infrastructure including TAF, DSTS, and STS Infrastructures? Or do they just mean this PECE instance? If the latter, I have not used this instance of PECE much at all, except as a very very seldom reference point. I’m hoping to use world pece for the PECE for Pedagogy project.
But if you mean the former. I have used STS Infrastructures for the STS Across Borders project. With Eliza Nobles (now a Drexel alum), we built Animating STS @ Drexel University in 2018. I have also used DSTS for the Writing Slow Disaster workshop which was held as part of the Society for Cultural Anthropology’s first virtual meeting. This workshop was designed with Tim Neale and facilitated at Drexel University with Scott Knowles. We used this space to post readings for workshop participants and artifacts in advance of the meeting. We were supposed to add material from the workshop after the event, and continue working with it, but we never did. Maybe that’s still possible.
I have used The Asthma Files the most out of all four platforms. I have used TAF for my research in Philadelphia, using the 6+Cities groups. I have used TAF to teach two classes, Philadelphia Civic Field School, which was a four week, 300-level special topics course taught at Drexel; and Philadelphia in a Changing Climate, which was a STS graduate lab course taught in spring 2017. I have had somewhere between 24-30 Drexel students work on the platform over the years, between these two classes and RA-ships. I have also set up four groups there that I don’t use that much 1) Knoxville, 2) Urban Climate Action and Research, 3) Housing Philadelphia, and 4) Mobile Asthma Apps. I have added artifacts to these groups over the years, but haven’t done much beyond that. I have created a number of analytics, such as the 'Data in Service' analytic and the profiling a climate policy analytic for Urban Climate Action and Research.
