Abstract
Across all levels of education, Natural Sciences is a scientific field that is gaining considerable research interest. However, in recent years a growing interest in the introduction of Science in Preschool Education can be seen among scientists, as they realize that the children’s first experiences will be the cornerstone of the relationship they are going to develop with this scientific field in the future. It is accepted that children approach and understand the new knowledge taught in the classroom in the context of what they already know. Their pre-existing beliefs and experiential knowledge are the foundations upon which the new concepts will be merged. Based on these perceptions, children approach, "decode," and understand new knowledge through the interaction of the two cognitive systems, the pre-existing and the taught new enriched cognitive patterns. The kindergarten environment cannot remain isolated and uninfluenced by the developments in a constantly changing world. The goal of Kindergarten is to properly prepare its students to become active citizens of their country by helping them get all the necessary skills. In this way, the STEM and STEAM approach seems to be progressively gaining ground in Preschool Education. Various researchers emphasize the importance and positive outcomes of implementing a STEM education program in Kindergarten, as children can acquire at an early age all the necessary resources that will play a decisive role in their later life. According to the above, this study is a literature and article review with its primary purpose to verify the above assumptions. More specifically, this article showcases the importance of teaching Science in Preschool Education and its practicability at this age group. There is also a presentation of the holistic educational STEAM approach. The main goal of this presentation is to emphasize the contribution of this educational approach towards a more effective teaching of Science in Kindergarten and in-depth learning and understanding of natural concepts by preschoolers.
