The assumption of the present study is that teachers should possess an adequate understanding of the nature of science and scientific method and hence this aspect was investigated. The empirical research carried out with Secondary School teacher trainees at Botswana colleges of education showed the following: Subjects possess an adequate understanding of some aspects of the nature of science and several aspects of the scientific method. They however do not have an adequate understanding on certain aspects of the nature of science. An association was found between the nature of science, type of educational institution attended, years of study and majoring in science. A positive association was found between scientific method and years spent studying. The present study recommended the inclusion of history, philosophy and sociology of science in the curriculum of teacher education. / Educational Studies / M. Ed.

Mémoire en recherche-création ; Aide financière octroyée : CIRMMT Student Award / Les conditions d'utilisation de théories scientifiques au cours du processus de composition musicale et plus généralement pour l'élaboration de théories esthétiques musicales sont au coeur du travail proposé. Une position critique est tout d'abord avancée relativement aux nombreux écueils historiques relevés. Elle permet d'en dégager quelques pistes d'exploration pour les processus compositionnels que je me suis proposé de suivre au fur et à mesure des pièces électroacoustiques et mixtes présentées. En particulier, des spécificités empruntées aux mécanismes vibratoires non-linéaires, aux modèles sociologiques déterministes ou prédictifs sont injectés au sein même des processus de création des mes oeuvres. Cinq pièces sont présentées. Les thématiques et les contraintes occasionnées par les modèles empruntés sont décrits ainsi que les réalisations techniques qui leur ont servi de support. Chaque pièce présente donc une démarche et des outils technologiques et informatiques particuliers. Ces pistes exploratoires feront intervenir contrainte formelle, limitation du contrôle du compositeur, improvisation, traitement et spatialisation en temps réel et développements originaux implémentés en Max/MSP et en Python. Par ailleurs, un outil d'aide à la composition spatiale proposant une perspective inédite de visualisation du champs de pression produit par les trajectoires et par le système de reproduction virtuel, et développé pendant ma maîtrise est présenté. / The use of science theories during the compositionnal process, especially in a purpose of esthetical properties abstraction is questionned. First, a criticist point-of-vue is adressed, on the basis of several historical examples. A personnal method dedicated to the development of original compositionnal process were deduced. In particular, the specific mecanisms related to nonlinear vibrations and deterministic sociological model could be inserted into the creative processes. Five electroacoustic and contemporay music pieces are presented. Themes and constraints provoked by the model insertion are detailed. They gather form-contraints, control limitations, improvisation, real-time processing and real-time spatialization implemented in Max/MSP and Python. Moreover, a refined sound-field rendering tool dedicated to computer-assisted composition is introduced.
