This document summarizes a study that examined academics' personal networks to understand how they support professional learning and teaching practice transformation. Interviews and surveys of 53 academics across different institutions and disciplines found they rely on two types of networks: interest-driven and task-specific. Their networks primarily consist of strong, local ties that provide socio-emotional support but limit exposure to new ideas. While networks facilitate knowledge acquisition, advice and encouragement, they may also reinforce existing practices. The study contributes a social network analysis approach to understanding academics' learning and offers insights into network composition.
