Studies and diplomas : PhD on didactics of scientific disciplines and HDR (French post-doctoral degree allowing its holder to supervise PhD students). My first research themes in didactics concerned the motivation and students’ attitudes related to science, with a focus on the gender question. Today I focus my work on the following themes: relationship to (socioscientifc) knowledge in Contemporary world, commitment, scientific education of the citizen in connection with the recent changes that have upset the curricula of teaching at an international level. I thus cross questions of policies and practices in science education, curricular reconfigurations, globalization, international assessments.
