09/07/2017	David Weintrop, University of Maryland, College Park	To block or not to block: Understanding the effects of programming language representation in high school computer science classrooms. Abstract: In the last few years, Chicago, New York City, and San Francisco have all announced major initiatives to bring computer science classes and computational thinking into every high school in their cities - with countless other smaller school districts following suit. Having made these commitments, attention now shifts towards how best to teach computer science to diverse populations of high school students who grew up in the age of smart phones, iPads, and Facebook. An increasingly popular strategy being employed is the use of graphical, block-based programming environments like Scratch, Blockly, and Alice. While these environments have been found to be effective at broadening participation with younger learners, open questions remain about their suitability in high school contexts. In this talk, I will present findings from a two-year classroom study looking at how the design of introductory programming environments affects learners' emerging understandings of computer science concepts and their perceptions of the field of computer science. I will also discuss the affordances of block-based programming environments relative to more conventional text-based alternatives. Bio:David Weintrop is an Assistant Professor in the Department of Teaching & Learning, Policy & Leadership in the College of Education with a joint appointment in the College of Information Studies at the University of Maryland.

09/14/2017	Stacy Branham, University of Maryland Baltimore-County	From Independence to Interdependence: A Social Narrative of Assistive Technology Abstract: In the Assistive Technology and greater disabilities community, “independence” has been a core goal and frame for making progress toward equality. This dominant narrative is often interpreted to mean that disabled people can and should live independently without help from others, and that assistive devices exist to displace reliance on helpers. For example, a wearable device that gives a blind person turn-by-turn directions through an airport displaces a sighted human guide. However, my work with people with disabilities in the home, in the workplace, and in public spaces has demonstrated that collaboration is a significant tool and goal of people with disabilities in their everyday lives. Further, social setting and human-human interactions significantly impact whether and how assistive devices are used. In this talk, I will share and unpack stories from people with various abilities to argue that assistive technology design through the lens of “interdependence” provides a more honest, respectful, and empowering alternative for assistive technology design. Bio: Stacy Branham is a Lecturer in Information Systems at the University of Maryland, Baltimore County (UMBC). Her research in Human-Centered Computing contributes to the subfields of Social Computing and Assistive Technology by investigating how technologies mediate interpersonal relationships, often with people who are blind. Her recent and ongoing studies explore how technology can engender safety as people with disabilities encounter law enforcement at protests, as blind parents care for their children at home, and as transgender people navigate violence in online and offline spaces. Themes she investigates include agency, empowerment, disability, gender, social justice, intimacy, interdependence, personal safety, and ethics in design research. Her research has been recognized with best paper awards at CHI and DIS. Dr. Branham has organized multiple workshops at CSCW and CHI on ethics in design research, culminating in a Special Issue of Interacting with Computers. She is currently a papers AC for CHI 2018 and the Chair of the Student Research Competition for ASSETS 2017. Dr. Branham received her BS and PhD in Computer Science from Virginia Tech, with a specialization in Human-Computer Interaction.
09/21/2017	Gabriela Marcu, Drexel University Cody Buntain, University of Maryland, College Park	Gabriela: Addressing health inequities through human-centered design Cody: Gaining Insight into Real-World Societal Response Using Social Media Talk 1 - Abstract: When we use empathy and human-centered approaches in developing health interventions, we have the capacity to affect social change. We can direct human-centered computing toward underserved populations. We can target marginalization, stigma, and inequity with human- centered methods. In this talk, I will share projects that have focused on addressing inequities within children’s behavioral health services, treatment for youth living with HIV, and opioid overdose prevention. I will present methodological approaches to designing for and with underserved populations, and show how to practice inclusion and equity in the design process. Based on the results of my projects, I will also outline design principles for health information technologies that do not sacrifice humanity for standardization. Finally, I will discuss the importance of broadening participation in computing, for more equitable research participation, methods, and output. Talk 2 - Abstract: Online social networking platforms (OSNs) like Facebook, Twitter, and Reddit have become valuable data sources in studying societal response to high-impact events (terror attacks, natural disasters, mass demonstrations, etc.). These events unfold rapidly, with users posting their responses and new developments to OSNs as they happen. Rapidly understanding these responses can be critical to providing assistance or reducing conflict. This talk discusses three main areas in this research: 1) How well does OSN data reflect real-world population data, 2) What are the patterns in response behavior to these events, and 3) How can low-quality information be filtered out from these data sources? I will present findings across these questions, showing social media data mirrors certain geographic populations, discussing event-detection algorithms, and outlining some current research in cross-platform information quality. I will then open discussion on future work in: OSN data for qualitative study, crisis informatics, and studies of population/platform differences in online information quality. Bio: Gabriela Marcu is an Assistant Professor in the College of Computing and Informatics and a Research Fellow with the A.J. Drexel Autism Institute at Drexel University. Her research applies participatory design, action research, and ubiquitous computing to promote behavioral health and social justice. Dr. Marcu directs the Empathic Research Group, a highly diverse and interdisciplinary team passionate about user experience and social change. She holds a Ph.D. in Human-Computer Interaction from Carnegie Mellon University, and a B.S. in Informatics from the University of California, Irvine. She has been named a Siebel Scholar, NSF Graduate Research Fellow, Microsoft Research Graduate Women Scholar, and Google Anita Borg Scholar. Bio: Dr. Cody Buntain is a postdoctoral research fellow at the University of Maryland’s Human-Computer Interaction Lab and is funded by the Intelligence Community Postdoctoral Fellowship. His current areas of research include studying complex social systems and how society leverages social media in the aftermath of crises and social unrest. This research includes evaluating information credibility across social media platforms, real-time information retrieval and event detection in response to crises, social media reflections of real-world phenomena, and the intersection of machine learning and computational social science.
09/28/2017	Mark Fuge, University of Maryland, College Park	Designing with Data: How machine learning is morphing human, product, and system design Abstract: The nature of product design has increased in scale, both inside corporations and in self-organized online communities (e.g., OpenIDEO, Local Motors). This is thanks to unprecedented amounts of digital design information made possible by globally distributed groups of thousands of people who collaborate together on design projects over the Internet. However, this increased scale and diversity comes with a price: 1) these groups generate more data than they can effectively use, 2) it becomes difficult to leverage their diverse expertise, and 3) involving non-experts meaningfully the design process, particularly for complex mechanical systems, requires rethinking how people interact with design tools and what kind of intelligent support we need to provide. In this talk I'll address how advances in machine learning can ameliorate these issues. Specifically, my students and I will introduce ongoing work on three problems: 1) how to use data to understand and simplify complex, high-dimensional, design spaces (to aid in techniques like optimization, design synthesis, and design exploration), 2) how to filter high-quality, diverse submissions out of large pools of design ideas generated by online communities (to aid in design generation and selection), and 3) how to enable non-experts to design complex mechanical parts (such as 3D printable robots) by using AI to automate various mechanical design tasks. Each problem highlights how building probabilistic models of designs via data can often produce a whole that is greater than the sum of its parts and make design (even of complex, physical systems) more inclusive. Bio: Mark Fuge is an Assistant Professor of Mechanical Engineering at the University of Maryland, College Park, and recently joined the HCIL as a faculty member.

10/26/2017	Janet Walkoe, University of Maryland, College Park	Technologically Mediated Teacher Noticing Abstract: We introduce technology-mediated teacher noticing (TMTN): a vision for the design and use of technology-mediated tools that takes seriously the need for teachers to attend to, interpret, and respond to their students’ thinking. This vision is situated at the intersection of research on teacher noticing, and on technology to support student thinking. We synthesize that work to highlight specific ways that technology-mediated classroom tools can focus and stabilize teachers’ attention on valuable aspects of student thinking emphasized by current reform efforts. We then illustrate TMTN with classroom examples in which technology supported or obstructed teachers' attention to student thinking, and consider implications for research on technology in teacher practice, professional development, and the design of technological tools for K-12 classrooms. Bio: Janet is a Learning Scientist and Mathematics Educator. She earned her Doctorate from Northwestern University in the Learning Sciences in 2012. She also holds an MS in Mathematics from the University of Illinois at Chicago and a BA in Mathematics from the University of Chicago.
