Introduction

The subject of this issue of “Elementary Education in Theory and Practice” focuses on popularising the results of Polish and foreign research and programmes that develop children’s scientific competences. The authors of the articles explain what STEM/STEAM education is, and what its objective and effects are. They combine theory and practice in an effective manner, which is why the reader can get to know and evaluate its assumptions, as well as practical solutions. In the countries of the European Union, good practices that develop children’s scientific skills are promoted because the society can grow economically and culturally only if it is based on knowledge.
