Nandana Weliweriya, Assistant Professor-Limited Term

Research Interests

Research (Physics Education Research)

I am interested in understanding students' processes of problem-solving. In particular, how students construct and coordinate among (use) representations (diagrams, mathematics, gestures ...) while solving physics problems.
