This paper investigates smaller-scale transitions that are part of the longer-term processes of subjective transformation and adaptation to new professional competencies for learners in the field of vocational education. On the conceptual level, it proposes to view transitions as intermediate states in situated trajectories of learning. The notion of trajectory aims to capture that (a) learning occurs through situated and highly contextualized micro activities and (b) that these activities occur within historical sequences of events, which come to form over time dynamic trajectories. The ingredients constitutive of a trajectory of learning are first defined. The notions presented are next applied to the empirical analysis of one sequence of learning, in which we show the transitions undergone by one object of knowledge as it is being taught to different apprentices in a workshop. On the theoretical plane, the paper thus proposes to view transitions as microdynamics of change. On the methodological plane, it contributes to identifying possible empirical sources and methodological frames to study micro-transitional phenomena.

When trainers or teachers in the field of initial vocational education explain abstract notions, refer to technical objects or emphasize the specificities of technical skills, they often call forth concepts and practices different from those that are directly salient in the training situations in which they engage. The aim of this paper is to contribute to a better understanding of the empirical realities associated with such phenomena by promoting a discursive and interactional approach of what we propose to term "analogical discourse". Considering that analogies are performed and shared trough language and speech, we propose that concepts and methodological tools borrowed from the field of linguistics can be profitably applied to the analysis of analogical discourse. Not only can they reveal the dynamic and collective nature of analogies as they are performed, disseminated and sometimes negotiated amongst participants, but they can also help reflect about the complexities of vocational learning as it takes place in specific material, practical and socio-cultural environments. From that standpoint, the paper proposes to see analogies not only as related to conceptual development and cognitive dimensions of learning, but as a substantial contribution to the social, cultural and relational dimensions of it.

Personal Homepages (HPs) belong to an emerging genre. Confronted with a kind of text which is still rather undefined, whose form and content are not freed and to which they haven 't had exposure before, authors of HPs tend to take as their model other personal HPs, thus ultimately participating in the conventionalization of a genre. By examining the system of deictic elements that can be found in personal HPs, I study these emerging patterns and show rules of function and stylistic characteristics of these texts. This ultimately leads to a tentative definition of the genre ofpersonal HP.
