Our approach to understanding mobile learning begins by describing a dialectical approach to the development and presentation of a task model using the socio-cognitive engineering design method. This analysis synthesises relevant theoretical approaches. We then examine two field studies which feed into the development of the task model.

Transitivity in trust is very often considered as a quite simple property, trivially inferable from the classical transitivity defined in mathematics, logic, or grammar. In fact the complexity of the trust notion suggests evaluating the relationships with the transitivity in a more adequate way. In this paper, starting from a socio-cognitive model of trust, we analyze the different aspects and ...

Research on concept learning in educational settings has traditionally been conducted in the Piaget-inspired cognitive conflict paradigm in which students’ naïve conceptualizations are confronted with anomalous data or contradicting views or are paired with peers who have different views (socio-cognitive conflict). Inducing conceptual change has been extensively shown to be a hard goal to achie...

The approaches to the trust study are various and very different each of other. In our view, just a socio-cognitive approach to trust would be able to analyze the sub-components (the basic beliefs) on which the final decision to trust or not is taken. In this paper we show a first implementation and advance of the socio-cognitive model of trust developed in [1, 2] using the so-called Fuzzy Cogn...

Research into the benefits of collaborative work on learning have shifted from questions regarding whether it promotes learning, to research into the conditions that promote learning and the identification of processes that make collaborative group settings particularly effective. In this symposium we will present findings from recent research into a number of socio-cognitive processes that hav...

Relevance has become a major area of research in the ®eld of Information Retrieval, despite the fact that the concept relevance is not well understood. This paper models manifestations of relevance within a system of relevance attributes to show that the attributes function in di€erent dimensions for the di€erent manifestations of relevance. It is shown that motivational relevance, as a manifes...

Empirical studies on design have emphasised the role of memory of past solutions. Design involves the use of generic knowledge as well as episodic knowledge about past designs for analogous problems : in this way, it involves the reuse of past designs. We analyse this mechanism of reuse from a socio-cognitive viewpoint. According to a purely cognitive approach, reuse involves cognitive mechanis...

This introductory paper explores how the use of information affects the effectiveness of early warning systems. By effectiveness, we refer to the capacity of the system to detect and decide on the existence of a threat. There are two aspects to effectiveness: being able to see the evidence that is indicative of a threat; and making the decision, based on the weight of the evidence, to warn that...
