Research

I am interested in helping people learn and reason better.

My research is in Interactive Learning and Reasoning.

That is, in the area of applied cognitive and learning sciences. It is about the design of external tools and environments that support human mental and knowledge-based activities.

 

One of the most important things that happened during the Industrial Revolution was the invention of machines that enhanced the physical capabilities of human beings. Whereas previously we needed to use our limbs to manipulate our environment and perform tasks, machines extended and enhanced our physical capabilities and transformed the nature of the physical tasks that were performed. They allow us to do much more, in a more efficient and speedy manner. Now, we live in the Knowledge Era. In this era, the ability to learn, produce knowledge, and think and reason effectively are crucial. In addition to tools that enhance physical capabilities, we now need tools that amplify and support our mental activities. The par excellence machine to do this is the computer.

 

Computers, due to their malleable, interactive nature, can act as powerful extensions and amplifiers of our mental activities. Since most of our learning and reasoning is through interaction with external representations of information and knowledge, I investigate how to design interactive software tools that enhance and support people’s exploration and understanding of these representations. My research is interdisciplinary, synthesizing models and theories of knowledge, computational, cognitive, mathematical, and learning sciences. The disciplines and a list of keywords describing different facets of my research are listed below.
