Quarante ans après l’apparition des ateliers philosophiques en classe (DVP), se pose toujours la question de la valeur effective et des retombées de ces pratiques sur les apprentissages et la socialisation. Le repérage et la caractérisation des mouvements de pensée réflexive est une question clé lorsqu’on s’intéresse à mesurer l’efficience de ces pratiques. La thèse contribue à étendre et approfondir l’étude des données langagières pour mettre à disposition de la communauté scientifique des résultats inédits concernant ces dialogues d’un genre nouveau. Le travail s’appuie sur une double collecte de données : au primaire et au collège. Les résultats de thèse sont disposés sur un triple niveau. Premièrement, nous avons pu caractériser les phénomènes de réflexivité en décrivant les philosophèmes, en prenant appui sur des marques formelles en langue pour rendre compte du processus dynamique de la pensée collective. Ce travail effectué à l’aide du logiciel de transcription et d’annotation linguistique ELAN a été possible grâce à l’élaboration d’une méthodologie inédite. Deuxièmement, nous avons élaboré des résultats didactiques ou nous avons dégagé quelques facteurs (niveau scolaire, âge, etc.) qui favorisent la réflexivité en classe et son développement chez l’enfant et qui sont particulièrement actifs et/ ou significatifs au sein de ces discussions. Finalement, dans la troisième partie, nous décrivons la mise en ligne du corpus du genre « discussion à visée philosophique » pour qu’ils servent de corpus de référence pour la communauté en sciences humaines, sur une plateforme spécialement conçue à cet effet : Philosophèmes. / Forty years after invention of philosophy for children (P4) by Mathiew Lipman, the question of effects of those workshops on children still remains present. Characterising of reflexive thought’s movements is a key factor while we are interested about measuring the efficiency of P4C on children. This dissertation has a part in extending the study of linguistics data issued from P4C workshops and makes available a quantity of results issued from this analysis. The work is grounded on double set of data issued from primary schools and secondary schools in France. The results are on triple level. Firstly, we characterised the reflexive phenomenon during P4C that we called philosophemes. We leaned on the formal language marks to highlight the dynamic process of collective thinking. This work, conducted with linguistic annotator ELAN, was possible by elaboration of specific and unique methodology. Secondly, we elaborated the results for a possible use by teachers, which concern the factors (pupils’ school level, age, etc.) that influence the thinking during P4C workshops. Finally, in the third part of work, we described the elaboration of internet platform Philosophemes when our results and corpora are available for the scientific and scholar communities.

This study provides a critical interrogation of the perceptions held by the undergraduate Philosophy of Education students at an open and distance learning institution, towards African philosophy. The study is premised on famed Kenyan philosopher, Odera Henry Oruka‟s classification of African philosophy into four trends: ethno-philosophy, philosophic sagacity, nationalist-ideological philosophy and professional philosophy. These trends confirm that African philosophy is more than traditions, culture or ubuntu, and more complex than the students make it to be. The study makes a link between the students‟ flawed perceptions of African philosophy with their lack of critical thinking skills. The study has attempted to answer questions such as why students have flawed perceptions of African philosophy; how critical thinking assists in changing their perceptions of African philosophy, and what role can the education system play in equipping students with critical thinking skills. The study‟s findings show that undergraduate Philosophy of Education students conflate African philosophy with African people‟s traditions and cultures, and with ubuntu. Students perceive that African philosophy lacks reason and rationality - key elements of critical thinking. The study‟s findings show that students lack critical thinking skills. The study notes that the way students are taught makes a large contribution to their perceptions and lack of critical thinking skills. The study makes the following recommendations. Firstly, to deal with the problem of students‟ conflations, the study recommends the introduction of the principles of African philosophy, namely, ubuntu, communalism and indigenous knowledge systems (IKS) in the school curriculum, and to emphasise these principles in the curricula of higher education institutions. Secondly, the study recommends the introduction of philosophy for children (P4C) in schools. It is envisaged that P4C will assist learners to acquire critical thinking skills at an early stage of learning. Thirdly, the study recommends the teaching of critical thinking skills at universities. Finally, the study recommends that in- service training be made an integral part of teachers‟ and lecturers‟ professional training, to bring them up-to-date with new ideas and methods of teaching. / Educational Studies / D.

This dissertation offers a philosophical analysis of the ecological crisis through the lens of Hannah Arendt. It frames the ecological crisis as a struggle for situated cohabitation. By analyzing the work of Arendt, this dissertation shows the ways in which the ecological crisis is entwined with the political crisis of plurality. I suggest that these two issues are interconnected and that we need to address both for situated cohabitation. This dissertation is an interdisciplinary work, drawing from environmental philosophy, feminist philosophy, and educational practice. The work is intended to provide novel insight into the current ecological crisis in three ways. First, it grounds its theory in the work of Arendt, a thinker not usually situated in the prevue of environmental scholarship. Second, by synthesizing Arendt's account of plurality with the work of Judith Butler and Ricardo Rozzi, this dissertation explores a politics of plurality that can take account of social and ecological conditions of plurality. Third and finally, the dissertation merges theory with praxis by offering a practical program for doing environmental philosophy with children, a program derived from my sustained experiences working as a facilitator of a philosophy for children (P4C) program. This dissertation does not seek just a theoretical understanding of the ecological crisis, but also a practice of situated cohabitation in the crisis.

Syftet med studien är att presentera ett designkoncept för publika diskussioner på nätet med målet att uppnå djupare diskussioner och minska mängden information overload. Arbetet använder metoden Concept Driven Interaction Design (CDID) som går ut på att skapa ett designkoncept utifrån flera olika teorier som appliceras genom interaktionsdesign. Ett designkoncept innehåller tre delar: ett namn, ett syfte och huvudprinciper. CDID innehåller sju steg som arbetet är utformat efter: 1.      Concept Generation – Summeras i en tabell som jämför diskussioner i forum (med flera antagande) och diskussioner med hjälp av metoden Philosophy for Children (P4C), samt annan teori. 2.      Concept Exploration – Åtta olika designaspekter identifieras utifrån jämförelsetabellen. 3.      Internal Concept Critique – Designaspekterna jämförs med två snarlika diskussionsformat. 4.      Design of Artifacts – Designkoncept version 1 skapas. 5.      External Design Critique – Intervjuer utförs för att undersöka intervjupersonerna generella erfarenheter av online diskussioner, testar antagandena från jämförelsetabellen och ge direkt feedback på första versionen av designkonceptet. 6.      Concept Revisited – Ändringar görs baserat på intervjumaterial och direkt feedback. 7.      Concept Contextualization – Designkonceptet kopplas tillbaka till litteraturen. Studien resulterar i ett designkoncept kallat CoFramer och stödjer dessa huvudprinciper som ställs i kontrast till material som identifierats genom intervjuerna: Tabell 1: CoFramers huvudprinciper och faktorer från intervjuer om diskussioner på forum. CoFramers huvudprinciper | Från intervjuer om diskussioner på forum Strukturerad början och slut | Diskussion utan tydligt slut Begränsat antal deltagare | Stor mängd deltagare Minimum antal deltagare | Många inaktiva åskådare Explicita deltagare | Lite information om deltagare Gemensamma förutsättningar | Otydlighet kring deltagares förutsättningar Begränsad informationstäthet per inlägg | Långa inlägg och/eller snabba inlägg Den röda tråden och parallella trådar | Oftast parallella trådar Aktiv samtalsledare | Outredda missförstånd Studien indikerar på att CoFramer bör resultera i mer strukturerade diskussioner och som utsätter användaren för en lägre mängd information overload och mindre grounding cost jämfört med vad som vanligtvis uppstår i publika diskussioner online. / The focus of this essay is to develop a design concept for online public discussions with deep discussions and low information overload. The method used is Concept Driven Interaction Design (CDID) which involves constructing a design concept by applying a variety of theories in tangible interaction design. A design concept has three basic parts: a name, high-level goals and outlines generic principles. CDID includes seven steps which is used in this work: 1.      Concept Generation – Formatted into a table that compare forum discussion (with several hypothesis) compared to discussions with the method Philosophy for Children (P4C) and other theories. 2.      Concept Exploration – Eight distinct design aspects are identified from the comparison table. 3.      Internal Concept Critique – The design aspects are compared to three similar discussion formats. 4.      Design of Artifacts – Design concept version 1 is created. 5.      External Design Critique – Interviews are conducted to explore their general experience of online discussions, investigate the hypothesis from the comparison table and to seek direct feedback on the first draft of the design concept. 6.      Concept Revisited – Changes are made to the design concept based on the interview material and the direct feedback. 7.      Concept Contextualization – The design concept is related to the original literature. The result of the study is a design concept named CoFramer. CoFramer’s generic principles are summarized and contrasted against factors identified from the interview material in this table: Tabell 2: CoFramer’s generic principles and interviews about online discussions. CoFramer’s generic principles | From interview material on forum discussion Organized start and ending | Discussions without clear ending Limited number of participants | Large number of participants Minimum number of participants | Large number of inactive spectators Explicit participants | Low information about participants Common conditions | Vagueness in participants conditions Limited information density per post | Long posts and/or fast posts The red thread and parallel threads | Often parallel threads Active facilitator | Unresolved misunderstandings The study indicates that CoFramer would create more structured discussions with a lower amount of information overload and less grounding cost compared what normally arise in public online discussions.
