The processes of assessment have begun to take pride of place in considerations of online teaching and learning. As the technological means become more robust for bringing students together online, designs of various kinds of assessment tasks reflect greater reliance on the strategies of interaction, collaboration, cultural exchange and the use and creation of Web resources. Where students living in different countries study online, their sharing of culture and perspective and their development of communication skills can be considered as elements of global learning. Best practice in assessment of global learning outcomes is still emerging from action research, as described in the case studies that are presented in this paper. The three case studies deal with consumer behavior, women 's studies and elementary mathematics/science teacher education.
