From Electronic Documents to Problem-based Learning Environments: an ongoing Challenge for Educational Modeling Languages

This work reports an evaluation of two educational modeling languages for the design of environments dedicated to problem-based learning (PBL) situations. Firstly, we assess the expressivity of the IMS-LD language against the requirements of the Smash case-study. Considering the limits of the IMS-LD language, we present some capabilities of the CPM language to describe other views representing contextual didactic choices (actions and events) that IMS-LD cannot afford. An analysis of the details of these CPM views has shown that they refer to learning/tutoring actions to be performed from the semantics of the electronic documents exploited in the Smash situation. Since it is a widely shared tendency to specify learning activities that take advantage of the information embedded in documents, we present some techniques, methods and tools to engineer together the educational capabilities of a corpus of electronic documents and the dynamics of learning activities enhancing the value of such a corpus. The only documents addressed by these research works are those embedding spatial and temporal information

Pattern-Based Guidelines for Coordination Engineering

This paper focuses on coordination engineering. We state that coordination engineering can be approached through a double point of view. On the one hand, coordination problems are recurrent and on the other hand, tested forms of coordination exist. We define a typology of coordination problems that can be solved by the enforcement of well known coordination forms. We highlight a correlation between our approach and the context-problem-solution formulation of patterns. We present a catalogue of coordination patterns that makes an inventory of a set of coordination problems, and a set of solutions that describe how these problems can be solved. After describing an example of coordination pattern, we finally present guidelines that use the catalogue in a framework of process coordination engineering.

Genre potentialities for interactive applications design and acceptation

In this paper, we propose to provide interactive applications designers with an approach that enhances the notion of Genre through design process, evaluation and acceptation of interactive applications. We firstly present a brief introduction of the Genre dimension. Then, we propose a Genre-based taxonomy of interactive applications, a model of Genre, a catalogue of patterns and a Genre-based chart as potential artefacts that enable consideration of Genre through design process. Finally, we expose the contribution of Genre in evaluation and acceptation processes.

Specifying Contexts for Coordination Patterns

This paper focuses on coordination problems resolution. We state that contexts delimit environments where coordination problems are recurrent. Thus, identification of coordination contexts is necessary to propose solutions that solve coordination problems. We propose a pattern catalogue where each pattern describes how to apply a coordination form to manage a given coordination context. Contexts and problems are described using the terminology of the concerned area; patterns describe how to apply a solution to a specific problem.

Prise en compte du genre pour la conception d'applications interactives : Propositions et expériences

This paper, which leans upon literary aspects of genre and belongs to Human-Computer Interactions domain, aims to present genre dimensions enhancement within interactive applications design process. We explain how genre contributes to mental picturing of interactive applications and participates to improve their acceptability. We propose some genre centred guidelines for interactive applications design which derive from verbal interactions. We define a set of steps in design process, a graphical notation which helps specification of interaction scenarios, and some genre centred evaluation criterions. Then, we introduce an experimental development process of two interactive applications carried out according to our approach. Finally, we evaluate the produced applications utility, usability and acceptability, and the design resources provided to development teams.

Valoriser la dimension genre dans le processus de conception d'applications interactives

Traditionally belonging to the Literary field, the Genre concept is the subject of an evolution from its Literary acceptance towards its Computer Science appearance. In this paper, we highlight these dimension potentialities in relation to the design process of interactive applications.
