IMPLEMENTING STEM-BASED CHEMISTRY PROJECTS

Abstract

The scientific-methodological article examines the theoretical foundations and practical aspects of subject integration within STEM education, particularly in chemistry lessons. It provides an analysis of the components of an integrated approach, highlighting interdisciplinarity, contextualization, cooperative learning, active learning, individualization, technological support, and the coherence of learning objectives. The significance of interdisciplinarity is emphasized, combining the knowledge from natural sciences, engineering, technology, and mathematics to encourage active cognitive engagement and critical thinking in students. The paper emphasizes the advantages of integrating the STEM approach, enabling the combination of chemistry with other sciences such as physics, biology, and mathematics. The author analyzes the effectiveness of implementing STEM projects in the chemistry curriculum. The specific STEM project example is presented as «Exploring the feasibility of using vegetable soaking as a method to reduce nitrate levels in vegetables» in the article, outlining an interdisciplinary approach to teaching chemistry and demonstrating the integration of chemistry with knowledge from physics, biology, and mathematics. The proposed use of artificial intelligence tools at the preparatory stage is noted, facilitating result prediction and method selection. The provided example illustrates that such an approach enables students not only to acquire theoretical knowledge, but also to apply it in practical situations, developing problem-solving skills in real-world contexts. The STEM approach is emphasized as a means of fostering systems of thinking and interdisciplinary connections among students. Through integrating chemistry with other disciplines, children can gain insights into the real-life applications of chemical knowledge, enhancing their understanding of fundamental chemical processes and principles. STEM education improves learning outcomes and prepares students for future challenges in a modern world where interdisciplinary skills are increasingly in demand. Implementing STEM projects supports not only scientific knowledge development, but also the formation of key competencies and essential skills necessary for further academic and professional success.

The author sequentially describes the stages of implementing the STEM project on «Investigation of the Feasibility of Using the Soaking Method to Reduce Nitrate Levels in Vegetables», as well as provides quantitative analysis methods for determining nitrate ions (NO3-), and presents an example of an instruction card. The article demonstrates the integration of chemistry with biology, physics, mathematics, and other sciences. Within chemistry, students study the chemical properties of salts and their impact on human health; biology examines the effect of nitrates on the body; mathematics is used for calculations; and computer science aids in data analysis and diagram creation.
