Since the implementation of the latest reform in the education programs of Quebec, the adaptation of teaching has taken on an important place in the concerns of all actors in education. However, this adjustment towards the adoption of teaching practices that require more participation on the part of the pupil is not accomplished so easily, particularly in the field of science and technology (ST). In order to gain a better understanding of these processes of adaptation, it is opportune to question ourselves on the factors and dynamics of interest at stake, especially in disadvantaged environments. Such environments are faced with situations where other difficulties coexist: integration of pupils, lack of interest, problems in classroom management, multi-ethnicity, etc. As a result, such difficulties give rise. to particular limitations, expressed in the form of needs, by pupils and teachers, likely to have a restrictive effect on the adaptation of teaching practices. Accordingly, our research focuses on the needs perceived by teachers in high school ST classrooms in disadvantaged school environments, since they present a privileged means to better understand the processes involved in the adaptation of practices. The adoption of an ecosystemic perspective, centered on these needs and their contribution towards the dynamics of decision-making, enabled us to better apprehend the complexity of these processes in ST classrooms. We were able to identify the needs perceived by teachers by following the methodology of conceptanalysis of needs, and by combining focus groups with the DRAP software. The results account for the large variety of needs to be considered in the equation of adaptation of teaching practices. These needs generally belong to the classroom system (microsystem). For pupils, they are mainly cognitive needs, but for teachers, they pertain to organization and structure. The influence of these needs on the adaptation processes depends on the interpretation by teachers of teaching situations, so much so that a same need can at times be assumed as negative pressure, generating obstacles, or at other times as a positive impulse, facilitating adaptation.

Learners in disadvantaged environments are less likely to do well at school. Yet some of the most successful schools operate in such environments. The purpose of this study was to establish the relative influence of various determinants of school success in disadvantaged environments. To this end literature study was done in two phases. The first resulted in a taxonomy of success factors, which was then used to guide the second in-depth phase. Thereafter an empirical study was done, involving qualitative field work at four successful schools in disadvantaged environments. Empirically it was discovered that there is no single most important success factor because all success factors are interrelated and interdependent. The over-arching success factor discovered in this study which was involvement of all stakeholders. / Education / M.Ed.
