Computers have been used in education in a variety of roles, some of which try to replace teachers and/or lead students down pre-determined paths. In contrast, the INK-12 project has studied how tablet computers with digital pens can be used to expand students’ repertoire of mathematical representations and support the growth of their mathematical reasoning with visualizations, particularly around multiplicative structures. The projects have also considered the ways in which computers can help teachers adopt more effective pedagogical strategies by providing them with timely information on their students’ work. Andee Rubin will describe the software the project created, the ways in which it has been used in elementary school classrooms, and what we’ve learned from automatic analysis of students’ representational work.


Andee Rubin is a mathematician and computer scientist who has been combining expertise in technology design, math education, and artificial intelligence to improve math and science education both in and out of school for over 30 years. She has led projects to build and study software for elementary math education (MIT ink-12), support high school teachers in having students construct infographics (Science Infographics), use log data to support learning in museums (NYSCI Connected Worlds), consider how mathematics is used in making (TERC Math in the Making) and study how students and teachers use software tools to visualize data. She was a graduate student in the MIT Artificial Intelligence Laboratory and worked at Bolt Beranek and Newman before coming to TERC in 1990.

Can a Free Wearable Activity Tracker Change Behavior?

Innovations in digital health have led to expensive toys, but have they improved health outcomes? Lisa Gualtieri will discuss the current landscape of wearable digital technology, and report on a series of studies on wearable activity tracker use in older adult populations; most notably, what was learned about acceptance and use of trackers that were provided free with training, and their impact on behavior change. She will also present on future directions her research is taking to potentially expand the usefulness of these devices as part of clinical care, to lower the prevalence of chronic disease within the US. Finally, she will showcase her non-profit, RecycleHealth, which she founded two years ago to collect trackers for underserved populations who need help improving on health behaviors. One such population includes veterans, a group of which will receive trackers as part of a wellness program through HutsForVets, with the aim to increase physical activity and improve mental health outcomes.

Soft interactive surfaces for tangible and wearable user interfaces

Unfortunately, “Soft interactive surfaces for tangible and wearable user interfaces” has been canceled. Stay tuned for an announcement about our September talk.

Central aspects of Mark Weiser’s vision of Ubiquitous Computing have become reality. However, the rigid nature of today’s interactive surfaces is limiting in several ways: it not only restricts the embedding of user interfaces in the physical environment, but also limits mobile use, interaction, and customization. These problems can be addressed through a research focus on future forms of interactive surfaces which are deformable, stretchable, and support multi-modal interactions.

This talk will give an overview of recent work on deformable sensor and output surfaces. Starting from sensors and displays on paper-like surfaces, it will introduce techniques for realizing interactive temporary tattoos. These conform to fine wrinkles and highly curved body locations, and turn the human skin into an input and output surface. Lastly, the talk will present approaches for making 3D printed objects interactive, by embedding conductive structures.

Together, these approaches demonstrate the potential of digital fabrication and printed electronics for realizing sensors and output in new form factors, which are compatible with highly individual geometries and custom user preferences.
