My current master project works on the cognitive process involved in perceiving the magnitudes of varieties of quantities, especially the magnitude of relative quantities. One particular property of relative quantities is that their magnitudes are determined relationally. Previous research has shown that space and number are closed connected. One classical example is the spatial numerical association of response code effect, also named as SNARC effect. My master project aims to test whether the association exist between space and relative quantity, taking non-symbolic ratio as the example.

Besides, I am also working on a perceptual based educational intervention project which try to strengthen the links between symbolic and non-symbolic representations of fractions, and thereby improving knowledge of symbolic fraction magnitudes and symbolic fraction knowledge more generally. I also work on a longitudinal project investigating the development of fraction knowledge in children. This longitudinal project, which will follow children in second and fifth grade for four years, works to better understand how basic perceptual abilities rooted in the human brain support the learning of fractions.

I also work on a cross disciplinary project with people from psychology and computer science department. This project aims to develop optimal teaching or training problem set that can speed human learning. The project combines computational cognitive modeling method from psychology discipline with optimization techniques from machine teaching discipline. The approach is currently being tested with arithmetic problems, but can be used to boost human learning in any learning tasks or in important education domains. So, this is me, an educational psychology student who studies mathematical cognition, cognitive development, and learning optimization. If you would like to know more about me or the projects I work on, please see our OMELET project page and read this blog post on computational cognitive modeling.
