Draw a social network

Abstract

We investigate the effect of graph theory instruction on the representations of social networks by grade six students. In this quasi-experimental study, treatment groups participated in graph theory lessons as part of their mathematics class. In evaluating student responses to pre and posttests we observed that students shifted in their approach to representing a social network problem, from less to more abstract - starting with complex vertices (superfluous detail) and planar graphs (no crossed edges) toward simple vertices and non-planar graphs.
