This thesis initiates from the empirical researches findings which indicate that cognition-action gap exists in knowledge sharing practice. In order to have a deep insight, the researcher conducts a phenomenological qualitative research to explore the context behind this phenomenon. We adopt phenomenological interview technique to explore the lived experience concerning knowledge sharing in knowledge management systems (KMS) called SCTNet. We interview forty-nine teachers who register as the members on SCTNet and are located in different cities in Taiwan. Research findings show that the meaning of knowledge that teachers perceive are¡G the techniques and lived experiences accumulated from the interactions with children¡¦s parents and children, teaching professions and designs, and the beliefs in teaching. The teachers perceive knowledge sharing as the transit power in transforming oneself from alone to belong to the teacher¡¦s professional community and helps oneself expands his/her experience from limited into broader. We find that teachers¡¦ interaction happened in five different fields in the school. These are the places of workshop, demo, gossiping, apprenticeship learning, and ¡§the space between you and me¡¨. In each field, there exist different phenomena of interactions. In the fields of workshop, demo, gossiping and apprenticeship learning, most of the interactions are perceived as a ¡§form of play¡¨, and only little lived experience is shared in these places. Most of lived experience sharing and learning happen in ¡§the space between you and me¡¨. Research findings indicate that the constrains frame these teachers in speaking out of their lived experience are¡Gthe norms of teacher society, busyness, and loneness. These teachers show their desires in looking for ¡§others¡¨ as the learning and sharing partners in SCTNet. Yet, they show different participation phenomena while they present themselves in the virtual space and these phenomena outline two forums for interaction in SCTNet. One of them is ¡§Smart¡¨ platform and another is ¡§Outside¡¨. On the ¡§Smart¡¨ platform, teachers perceive themselves as smart teachers and show strong group identity to this platform, share their lived experience actively, and always give support while partners need. They defense against outsiders while others criticize their platform. However, the members and their behaviors in sharing on ¡§Smart¡¨ platform are through the security check and guaranteed the sharings are safe. The phenomena in ¡§Outside¡¨ show that most of the participants keep quiet or with few interactions to hide themselves from the ¡¨others¡¨ on SCTNet. In this area, a lot of teaching materials are stored and used by the novices or the travelers on the virtual space. Sometimes, ¡§Outside¡¨ serves as the communication channel of the educational administration for transfering the documentations. Yet, with the administration intervention, participants are encouraged to submit or post some materials upon the ¡§quantity¡¨ request. This makes the SCTNet under the risk of becoming an information junkyard (McDermot 1994). Research findings also indicate the factors which serve as obstructs, exits, and projections that teachers tour around the physical and virtual space. At the end, several reflections are proposed from the perspectives of educational contexts, teachers, and information technologies for constructing the knowledge management systems.

L'Approche Centrée Patient (ACP) permet sur le plan conceptuel la réalisation d'une démarche éducative vis-à-vis du patient diabétique de type 2. Mais la question de son fonctionnement se pose en pratique clinique de médecine générale. Dans le cadre d'une étude exploratoire qualitative phénoménologique, une Démarche Educative DEADIEM a été testée auprès de 10 patients diabétiques de type 2 inclus par 5 médecins généralistes pour en comprendre son fonctionnement. Cette démarche comprenait l'exploration de la perspective du patient, ce qui est VRAI (Vécu, Représentation, Attentes, Important) pour lui, une démarche explicative, des conseils hygiéno-diététiques adaptés et un objectif de compréhension commune avec le médecin avec évaluation à 3 mois de ses résultats. En confrontant les données du discours avec les modèles transthéorique et transactionnel par procédure de triangulation théorique, cette démarche a corroboré une dynamique d'adaptation « coping », des processus expérientiels et comportementaux favorisant ou pas des changements. Les médecins traitants ont été sollicités pour parler de leur perception de la relation. L'étude a illustré l'interaction symbolique qui existe entre des représentations « personnages » que chacun se fait de l'autre et qui peuvent bloquer ou faciliter la relation et la compréhension commune. Les médecins traitants ont pu exprimer de manière réaliste leurs limites et les difficultés de la relation transférentielle. A l'issu de cette étude, l'ACP, enrichi par d'autres modèles, est apparue comme un processus thérapeutique systémique qui peut être accessible à tout médecin généraliste, enseignable et faire l'objet de travaux de recherche complémentaires / The Patient Centered Approach (PCA) allows, on the conceptual level, to undertake an educative counseling program for type 2 diabetic patients. The question of its efficiency remains unclear in everyday general practice. In the setting of an exploratory phenomenological qualitative research DEADIEM, an experiential educative counseling based on a patient centered care model, was tested on a population of ten type 2 diabetic patients selected by five general practitioners to understand its functioning. This study investigated the patient’s perspective, their real experience, beliefs, expectations, references. An explanatory procedure and adapted hygieno-dietetic counseling was proposed together with an objective of common ground between patient and practitioner. The results were evaluated after three months. By triangulating data extracted from the patient’s transcript with other transtheoretical model and transactional models, the study revealed coping dynamic, experiential and behavioral processes which favoured or not changes. General practitioners were asked to express their perception of the physician patient relationship. The study illustrated the symbolic interaction existing between the “personal fronts” representations that anyone has about others that may block or facilitate relation and common understanding. GPs have been able to express in a realistic way their limits and the difficulties of transferential relationship. At the end of the study, PCA, enriched by other models appeared as a systemic therapeutic process that can be of ready access to any GP, can be taught and must be the subject of further research
