Évolution du vivant et hasard : étude quantitative des conceptions d’élèves de collège dans le contexte français

Abstract : Evolution of living species is a major concept for the contemporary biological sciences, but also a complex object of teaching by the nature of the scientific concepts associated and the pupil’s conceptions. Teaching the evolution of living species is a challenge considering the complexity of the concepts involved, the particular reasoning process calling for a historical approach, and the strong beliefs held by students that may impede their learning of evolution. In France, the evolution of living species starts in primary school based on the idea of unity and diversity of living species and the biological classification. This teaching becomes well identified only at the end of compulsory schooling. This study aims a better understanding on the change of the conceptions of secondary school students along junior high school and how their conceptions of randomness can influence their acceptation and their understunding of the evolution of living species. Consequently, a questionnaire, UnRESt has been elaborated to study the mainstream conceptions of more than 1600 students about the evolution of living and randomness and to find potential links between these two types of conceptions. The UnRESt ingineering is based on exploratory studies (open-ended questions on the evolution of the living species and philosophical discussion). The study shows that a half of the students accept the evolution of living species and a third of them seems to have an understanding in opposition with an evolutionist understanding. According to the species studied, difficulties remain to explain evolution mechanisms. A ‘transformist’ vision of the evolution of living species is favoured by student. The study highlights also that the acceptation and the understanding of the evolution of living species are related to the students’ conceptions of randomness. More specifically, the results show an obstacle in the use of the word randomness with the meaning of contingency and an influence of their vision of ‘probabilist’ randomness on their understanding of the evolution mechanisms. The research concludes on the place to give to the scientific concept of randomness in the teaching in secondary school in order to create links between disciplines.
