Mobile language learning in India - we are winding down an academic-year long comparative pilot study with 250 children in 4 low-income schools in India. Here, disadvantaged children learn English as a Second Language -- an important gateway to economic opportunities -- using the educational games that we have designed for low-cost cellphones.

Culturally congruent curriculum design - the above games incorporate a curriculum framework that we designed for one entire academic year of ESL lessons. It draws from pertinent theories of monolingual and multilingual reading development (>50% of the world's population is multilingual!). It targets the local state government's ESL curriculum, and bridges the gap between this standard and the limited ESL proficiency that disadvantaged rural children currently have.

Productive vocabulary practice supported by speech recognition - while computer-aided learning has mostly targeted passive vocabulary knowledge, speech recognition enables us to target active vocabulary. We have shown improvements on word reading scores among rural children in India, and are extending this line of research to smartphones in the US (recall Google Voice and Siri).

Kinesthetic learning via motion-sensing game scenes - based on the adolescent fiction for US middle school students, we are designing motion-sensing game scenes for the Kinect to understand how physical actions in videogames relate to learning and reading comprehension processes.

Physics learning videogames - this is part of a large DARPA funded project, in which we are designing and evaluating physics learning games for pre-K to 3rd-grade children in the US. I am working with Sesame Workshop to study learning and adoption in a national network of after-school programs.

Cross-cultural game design in India and China - we examined the game mechanics in 28 traditional village games from India, and contrasted these elements against those in contemporary Western videogames. This analysis enabled us to identify guidelines for designing culturally appropriate games for rural Indian children. This approach was replicated with traditional Chinese village games for rural children in China with promising early outcomes.

Gender empowerment - building on previous in-situ studies of mobile learning in Indian villages, where we discovered how caste and gender act as social fault-lines that affect learning and technology adoption, we have explored the space of technological possibilities for non-government organizations to impact girls and marginalized women in the developing world using mobile technology.

$10, 8-bit television computers - we studied how videogames on this low-cost device was used in peri-urban households in India, and identified implications for designing educational games for this setting. An open community associated with this project has designed and developed games for this platform for health, computer literacy, language literacy and STEM (science, technology, engineering and math).

Multiple-mice computer - this is another low-cost computing platform, in which a regular computer was adapted such that multiple mice input devices could be connected to it, thus enabling it to be shared by several children. I mentored a team of Master's students who designed and field-tested a collaborative learning game on this platform for their capstone project; they received the top prize from their department.

Microfinance in Uganda - I was part of a team of third-party evaluators who studied the Remote Transaction System, which was spearheaded by a consortium convened by Hewlett-Packard to improve the tracking of micro-loans to low-collateral borrowers.

Educational tablets - back in 2000 (way before the iPad!), we studied how wirelessly connected tablets could be used to promote small-group collaborative learning in large lecture classes.
