This document discusses the development of an Electronic Performance Support System (EPSS) to support the design of blended learning in higher education. It describes a collaboration between several European universities aimed at analyzing research on blended learning, developing blended learning models, and creating a community-based EPSS. The EPSS is being designed using a participatory approach, including scenarios, design sessions, user stories and use cases. It will provide templates, calendars, glossaries, handbooks, case studies, portfolios and search functions to support university staff in blended learning.
