This article serves as a critical approach to both the emergence and the identity formation of Early Childhood Science Education (ECSE) as a new scientific field, consolidated within the association of certain research divisions of Early Childhood Education, various branches of Psychology dealing with learning, and of Science Education. Consequently, we present research trends, orientations, and currents in ECSE, such as the study of children’s mental representations, the development of teaching activities, teachers’ perspectives, the preparation of teaching materials, scientific skills, diversity and inclusive education, the influence of the family, etc. Finally, we formulate some concluding remarks on research perspectives and the epistemological formation of ECSE.

Children’s everyday activities enable them to learn some science even before entering preschool education and children bring these ideas with them when entering education settings. Some of these ideas, or else mental representations, may not be compatible with what is generally accepted by the scientific community. This paper presents the results of an empirical study, focusing on the construction of a precursor model that can support children’s scientific learning, in relation to the phenomenon of change of the state of water. The research included 91 children aged 5–6 which participated in a specifically designed teaching intervention. The intervention lasted approximately 55 min and was conducted at eight stages, during which children’s predictions and explanations for simple cases of change of the state of water were recorded. The analysis of children’s responses suggests that the specific teaching intervention can have a positive effect on children’s thinking in relation to the change of the state of water. A considerable number of pre-schoolers were able to take advantage of their involvement in the teaching intervention and construct a stable precursor model to support the development of their understanding, in relation to the water change of state phenomenon. It appears that precursor models can function in the minds of young children as intermediaries between mental representations of reality and scientific knowledge and prepare children’s thinking, forming the basis for a cognitive path towards cognitive processing and the formation of more complex models. The proposed intervention is compatible with the model used in science education and it is proposed to be used in moderation and should not replace children’s learning through play.

This paper refers to learning situations which take place within the framework of a constructivist pedagogy. We shall present the results of research relating to the construction of elementary magnetic properties in preschool children. Five years old children, in small groups, had at their disposal different types of magnets as well as diverse objects which could be attracted by them. We formed the hypothesis that by performing various activities (playing) with them, the children on the one hand would discover the attractive force exerted on certain metallic materials and on the other would distinguish the objects which were not thus attracted. We also formed the hypothesis that the children would discover the mutual forces of interaction by manipulating the magnets. The teachers observed the activities, encouraged and questioned each child and intervened in order to help the children to coordinate their activities which were becoming more and more complex. The content analysis of the protocols gave us results which seem to confirm our hypotheses.
