The GRAPPLE project (EU FP7) aims at delivering to learners an adaptive technology-enhanced learning (TEL) environment that guides them through a life-long learning experience. To this end a general-purpose adaptive learning environment is integrated with a variety of learning management systems (LMSs), offering access to both learning material and to user model information from any LMS. This demonstration will show that within GRAPPLE (and its adaptive learning environment GALE), authors can develop\nadaptive learning material in different styles ranging from fully hand-crafted to completely automatically generated.
