Research

My research interests broadly center around educational technology, classroom learning, engagement, and culture. As such, my collaborations result from the interaction of these areas.

Educational Technology Across Cultures
Educational technology is typically designed in western, industrialized countries and exported to other countries around the world. However, some of the design choices may not fully consider the cultural values or norms of users in all contexts. We investigate how some educational technologies are deployed around the world, understand ways that users in a variety of countries may interact with the systems, and provide recommendations to designers. These recommendations allow us to work towards promoting for all users the ability to have richer interactive experiences with technology.

Improving MOOC experiences for non-native English speakers
Many MOOC (Massive Open Online Courses – eg Coursera, edX, etc) learners are not native English speakers, yet most MOOC content is created and deployed in English. One widely assumed adaptation for these students is to translate all of the content into their mother tongue. However, we have found through interviews and observations that learners do not necessarily want this – some learners prefer to take a course in English to learn the content in English. We explore the social, economic, and geographical motivations of MOOC learners, especially those who are non-native English speakers, to discover appropriate adaptations that courses can consider for each of these learners.

Global Learning Council
In collaboration with the Global Learning Council, I am part of a team writing a white paper that will review existing research on educational technology, its design and effectiveness – at this point, about 400 papers and counting – and write our recommendations for how educational technology should move forward as a field for the next five to ten years.

Past research collaborations:

The ArticuLab
The ArticuLab studies how people communicate with and through technology, particularly in areas of minority dialects and rapport-building. During my time in this lab as the Lab Manager, I also had the opportunity to contribute to some of its research projects.

SimStudent
The practice of learning by teaching – which says that teaching something to someone else helps solidify it in your own mind – underlies SimStudent. In this program, students work on algebra problems with SimStudent, the student’s virtual peer, and answer its questions along the way. The papers below cover many different classroom interventions, with a variety of experimental and control conditions.
