Cette thèse propose un test empirique du modèle d’attribution du leadership basé sur l’observation de dyades leader-subordonné au Sénégal et en France. Ce modèle se concentre sur des construits essentiels comme la complexité attributionnelle et l’exactitude des attributions des leaders, les comportements qui en résultent, les variables médiatrices comme la satisfaction des subordonnés, les stratégies correctives de la performance et les variables de résultat comme les perceptions du leadership. Le modèle est testé à l’aide de régressions hiérarchiques des effets directs et des effets médiateurs des attributions biaisées. Notre intention est de tester les relations à partir d’un échantillon d’auditeurs en formation continue de l’enseignement supérieur (au Sénégal et en France) et de déterminer selon notre modèle et nos hypothèses de recherche, quels construits contribuent le plus à expliquer la complexité attributionnelle des leaders. Cequi nous amène à étudier l’influence directe de l’exactitude des attributions, l’effet des stratégies correctives et de la satisfaction des subordonnés sur la perception du leadership. Nous testerons aussi le rôle des attributions biaisées sur les deux variables médiatrices. Les hypothèses sont fortement corroborées. La complexité attributionnelle des leaders est liée à l’exactitude de leurs attributions, telle qu’elle est perçue par leurs subordonnés. Les stratégies de correction de la performance élaborées par les leaders se sont révélées liées à des attributions exactes, puis à des variables clés de résultats. Nous analysons les résultats ainsi que les limites et les orientations futures de la recherche. Les contributionsmanagériales sont doubles : d'une part, de prendre en compte dans le processus de recrutement des leaders leur aptitude à adopter une approche attributionnelle complexe et, d'autre part, les former afin de mieux accompagner leurs subordonnés. / This thesis proposes an empirical test of the leadership attribution model based on the observation of leader-subordinate dyads in Senegal and France. This model focuses on key constructs such as attributional complexity and leader attribution accuracy, resulting behaviors, mediating variables such as subordinate satisfaction, performance corrective strategies, and outcome variables such as leadership perceptions. The model is tested using hierarchical regressions of direct effects and mediating effects of biased allocations. Our intention is to test the relationships from a sample of auditors in continuingeducation of higher education (in Senegal and France) and to determine according to our model and our research hypotheses, which constructs contribute the most to explain the attributional complexity of the leaders. This leads us to study the direct influence of the accuracy of the attributions, the effect of the corrective strategies and the satisfaction of the subordinates on the perception of the leadership. We will also test the role of biased assignments on the two mediating variables. Hypotheses are strongly corroborated. The attributional complexity of leaders is linked to the accuracy of their attributions, as perceived by their subordinates. The performance correction strategies developed by leaders have beenlinked to accurate attribution and then to key outcome variables. We analyze the results as well as the limits and future directions of the research. The managerial contributions are twofold: on the one hand, to take into account in the process of recruiting leaders their ability to adopt a complex attributional approach and, on the other hand, to train them to better support their subordinates.

This study investigated how lesson study, a Japanese intervention tool, may be used as a management strategy to improve performance in space, shape and orientation in Mathematical Literacy at Technical and Vocational Education and Training colleges. In this study a qualitative approach was followed in both the pilot and the main study. Prior to the main study, a small-scale pilot study was conducted which consisted of two participant lecturers and lasted for about two months culminating in one complete lesson study cycle and a second partially completed cycle. Four lecturers participated in the main study which lasted about seven months from the last week of February 2019 to the last week of August 2019 at a campus of a TVET college where Mathematical Literacy is a subject in the NCV program. Data were collected from semi-structured interviews with lecturers and students, observations of students’ performance and behaviour while delivering the research lessons, including researchers’ journals and participant lecturers’ journals, students’ work and meeting notes which included debriefing notes. The LS - Participative Management model proposed in this study has shown to achieve the broad teaching and learning outcomes, personal and professional outcomes and managerial outcomes. Hence, it is possible that the model proposed in this study is an appropriate model which can be successfully implemented at TVET colleges in South Africa. With the application of the LS Participative Management model, findings revealed from this study showed that participant lecturers improved their teaching and learning by reflecting and engaging with the content of space, shape and orientation in Mathematical Literacy by highlighting the misconceptions students have around this topic. Participant lecturers were also brought out of isolation, giving them the opportunity to collaborate with other lecturers and the manager. Collaboration and participation in lesson study also brought about organisational effectiveness which was revealed through vigorous discussions, openness, trust and respect, positive relationships and sharing ideas. Lesson study also provided an enabling environment for lecturers to become personally and professionally empowered by increased confidence and motivation as they gained more experience in lesson study. The involvement of the manager as a participant observer showed that it can impact on curriculum management, sharing experience and expertise, influence the organisational culture and provide guidance and support. / Educational Management and Leadership / D.
