Mobile computing devices facilitate mobility and face-to-face interaction when compared with desktop computing, but lacks of the computing power of the latter. Therefore, a key aspect to ensure success of a learning supporting mobile application is whether mobility is really needed for the activity it supports and if mobile devices do really represent an added value compared with the same application implemented on non-mobile devices. In this work we first analyze the best known collaborative learning practices trying to find out which are the real need for mobility and faceto-face interaction and then design and develop an application called MC-Supporter implementing a, problem-based, collaborative learning application based on these requirements.
Abstract. This paper proposes a conceptual model standardizing the meeting information structures underlying several scenarios o PDA use in meetings. The paper characterizes the memory and process components necessary to support XML-based interoperability between meeting systems. The scenarios, information model and architecture were validated through their adoption in three applications, developed by different teams and covering quite different domains. The applications, encompassing several meeting scenarios and adopting multifaceted device combinations, demonstrate the high level of interoperability supported by the proposed conceptual model.
Knowledge Management (KM) is gaining more an more interest among high-ranked executives in organizations of diverse kind. Consequently, many systems have been developed claiming they are Knowledge Management Systems (KMS). In this work we present a KMS that tackles some problems most existing KMSs sit have not: Ubiquity, Collaborative Knowledge Management, Context-sensitivity. It also tackles the problem about privacy and fears people may have to reveal the knowledge they posses. The system supports its user in the processes of knowledge creation, validation, distribution and use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
