Teaching and Learning in Uncertainty

We investigate a simple model for social learning with two agents: a teacher and a student. The teacher's goal is to teach the student the state of the world; however, the teacher himself is not certain about the state of the world and needs to simultaneously learn this parameter and teach it to the student. We model the teacher's and student's uncertainties via noisy transmission channels, and employ two simple decoding strategies for the student. We focus on two teaching strategies: a “low-effort” strategy of simply forwarding information, and a “high-effort” strategy of communicating the teacher's current best estimate of the world at each time instant, based on his own cumulative learning. Using tools from large deviation theory, we calculate the exact learning rates for these strategies and demonstrate regimes where the low-effort strategy outperforms the high-effort strategy. Finally, we present a conjecture concerning the optimal learning rate for the student over all joint strategies between the student and the teacher.

Combined art and science as a communication pathway in a primary school setting: paper and ice

A hybrid combination of art and science is used to communicate science in a primary school setting. The purpose of the work is to enhance student awareness of the science behind understanding the global climate system with a focus on the cryosphere. An experiment in communicating science is conducted by taking the collaborative experiences of a professional artist and scientist, which are then combined and projected onto an ostensibly everyday primary school classroom project. The tangible end result is a stand-alone contemporary art work that then is the focal point of community-based promotion of the science and creativity involved. A range of qualitative evaluation elements suggest that the approach does improve student engagement with the scientific approach and reduces the student's uncertainty about ``what science is''.
