    1. 1. Analysis of Inter-action in a e-learning community M. Antonietta Impedovo Paola F. Spadaro M. Beatrice Ligorio University of Bari (IT) ISCAR Settembr 2011 - ROMA
    2. 2. Introduction Online learning environments are often used in University education as discussion spaces, to construct knowledge, to negotiate meanings. How to analyse on-line asynchrony interactions? There is a need for theories about interaction and methods of analysis to understand the complexity of online interactions
    3. 3. Background Pragmatics is an aspect of communication thanks to which phonetics is shaped in meaning, and meaning is shaped in social actions Speech Action Theory (SAT) conceptualizes how messages pragmatically act, as gestures, and then effect on social activities (Austin, 1962; Searle, 1969) Activity Theory (AT) highlights various levels of social activity (Engeström, 1987; Leontiev, 1940)
    4. 4. Aims Observe the dimensions of the Activity Theory (AT) in an online learning environment: •How the AT dimensions occur in a learning forum? •How they contribute to the construction of meaning? Particular focus on interactions between two dimensions: Subject dimension and Object dimension.
    5. 5. Data data: 72 messages posted in a discussion forum in Synergeia (Ligorio & Veermans, 2005). participants: 10 university students (7 males and 3 female) participating to a blended course
    6. 6. Inter-Actions Network Analysis Step I : Discourse Analysis Step II : Content Analysis to identify elements of the AT a) Build the system of categories b) Segment posts in unicategorial portions c) Identify the relationships between elicitation of segments Step III : Social Network Analysis to identify the structure of the discourse. Nodes of a network of segments eliciting and elicited by segments
    7. 7. Network density= 0,10 Every functions of communication concurs to develop the discussion. Some functions have a more central role in generating concatenation of communicative actions. Other functions, instead, are not at all connected.
    8. 8. Betweenness centrality defines the flow of actions passing through a node. Modality of Interaction has the role of mediator the inter-action. Community is also crucial in mediating the concatenation between actions.
    9. 9. Conclusions Messages posted on the forum are not simple communication units. They contain a variety of communicative actions. • This study indicates:  which dimensions are more important in a university blended context offers some information to improve discussions in e-learning environments.
