Dichotomous Keys and Collections in Pre primary Education
This study aims to provide the necessary resources and motivation to develop the scientific competence in the second cycle of pre primary education in Spain. The aim of this paper is to contribute with proposals, such as the development of collections and dichotomous keys to study with children from three to six years old, taking into account the mathematical competence, the learning to learn competence, and the competence of interaction with the natural environment, so that scientific literacy can begin from the early stages of education. Undergraduate students of Pre primary Education Degree in Centro Universitario Cardenal Cisneros are used to studying with these procedures, which not only involve knowing the basic characteristics of the natural elements collected (organisms or inert matter) but also require the development of skills and abilities characteristic of scientific study.
