Impact des TIC sur le sentiment d'auto-efficacite des enseignants du secondaire au Niger et leur processus d'adoption d'une innovation

This study examines the development among high school teachers of feelings of professional competence and self-efficacy toward technical skills through ICT training. It follows a project to pedagogically integrate ICT into a lycee initiated by the Campus numerique de Niamey (Niamey digital campus). After lycee teachers participating in a computer literacy project were trained in ICT, we undertook a follow-up study to appraise the impact of this ICT training, via the Niamey digital campus, on teacher adoption of the technologies. The research objectives were the following: (1) assess the impact of ICT training provided to high school teachers on the adoption process for these technologies; (2) describe and analyze the learning paths of the teachers who experienced a positive ICT adoption process; (3) better understand the impact of ICT training on feelings of professional competence in teachers (self-confidence and overall confidence); (4) validate the Computer Self-Efficacy Scale (CSE) in French; (5) understand the impact of ICT training on teachers' feelings of self-efficacy in computer use.;The results reveal no relationship between the teachers' ICT training via the digital campus and their level of technological innovation at school, according to the typology proposed by Hall and Hord (1987). ICT usage disparities among the teachers testify to this lack of association.;Moreover, it appears that the ICT adoption process in education is barely nascent in Niger. Indeed, only a few participants attained the levels of awareness and professional use, the first two of the four stages in Raby's (2005) typology of professional use.;The results show that feelings of personal competence differ between the two groups (trained and untrained teachers), although their feelings of overall competence were similar.;To achieve these objectives, a survey questionnaire was administered to 69 teachers from three lycees in Niamey and semi-directed interviews were conducted with six teachers. The thesis is presented in the form of a series of articles, each one addressing one or two of the research objectives in the above-presented order.;The results also show a significant difference in technical skill levels in terms of computer use between teachers who did and did not receive ICT training via the Niamey digital campus. The research strengths and limitations are analyzed and some recommendations are proposed to educational authorities.;Keyword.
