I am a PhD student in Computer Science department, Worcester Polytechnic Institute. I am interested in designing and building multimedia-based tutoring systems. I am exploring different ways of integrating game-like elements in a computer tutor. I am experimenting with cognitive, metacognitive and affective modes of such game-like interventions. I am also exploring causal mechanisms of how different interventions lead to the desired learning outcomes.

Prof. Joseph E. Beck is my research advisor and mentor.

My first three years (2008-2011) was sponsored by International Fulbright Science and Technology Award.

Since fall 2011, I have been working together with Dr. Ivon Arroyo and Prof. Beverly Woolf from Umass Amherst. During my years as a graduate student, I have also worked closely with Prof. Neil Heffernan and Prof. Ryan Baker from WPI and Prof. Matthew Kam from CMU.


PROJECTS


Wayang Outpost: It is an intelligent electronic tutoring system developed at Umass Amherst that uses multimedia and animated adventures to help prepare middle and high-school students for standardized math tests. I have been working with Wayang Outpost since fall 2011. I am involved in the design and development of new game-like interventions within the tutoring system and maintaining the system.

 


 

Monkey's Revenge: It is a math learning environment with game-like elements. It consists of a series of coordinate geometry problems wrappped in a visual narrative.

This project was granted WPI Grad day 2012 departmental award and was nominated for WPI innovation competition for 2011, 2012.

Mily's World: It was my first attempt to create game-like math tutor. But it was a big flop among students (they thought that puppy is too cheesy). Replacing the puppy with mischievous monkey in the same story did wonders.

Besides learning how to design and create effective tutors and employing data mining techniques for analysis and evaluation, these projects have allowed me a chance to play with stories and graphics design.

ASSISTments : It is a free web-based platform, hosted by WPI, that allows teachers to write individual ASSISTments (composed of questions and associated hints, solutions, web-based videos, etc.) I was involved in datamining of the user data from Assistments and I use Assistments user base (teachers are very supportive) for running studies with game-like interventions.

 


 

Mosaic, a math Game

 “Mosaic” is a math game where players solve math problems to generate tiles that can be placed inside a mosaic. There are mosaics of different cities from different countries. Each city is associated with a math skill, for example: New York is associated with ‘calculating area and perimeter’, Baghdad with ‘circles and arcs’ and Beijing with ‘triangles’..
