A type of awareness not previously known is presented. It concerns the understanding a group of people has about their shared knowledge. It is called Shared-Knowledge Awareness (SKA). It is introduced in the context of a collaborative learning scenario. The paper also presents a way of estimating the amount of shared knowledge a group has. A Shared Knowledge Indicator (SKI) is defined for this purpose. An awareness mechanism graphically presents the SKI on the user interfaces. The paper proposes to build the mechanism with an agent and two analyzer modules. A preliminary experiment was performed with collaborative learning groups. The SKI was manually computed. The numerical results show the groups did not care much about shared knowledge or its awareness.
