Methodology of using digital measurement complexes in the process of forming students’ research competencies in chemistry, biology, natural science, and human health classes

Abstract

The article explores the theoretical and methodological foundations for implementing modern digital measurement complexes (DMC) into the educational process of higher and secondary schools. The relevance of the study is driven by the necessity to modernise natural science education in line with the New Ukrainian School (NUS) standards and the integration of STEM technologies into the professional training of future chemistry teachers. The purpose of the article is to provide scientific justification and experimental verification of the effectiveness of using DMCs (such as Vernier and PhET) in developing research competencies during chemistry, biology, and human health classes. The study was conducted at Bogdan Khmelnitsky Melitopol State Pedagogical University (MDPU) involving students from the «Spectrum» research group of the Department of Chemistry and Chemical Education (n=45). The methodology focused on research projects utilising digital sensors for: pH-metry of various media; thermodynamics of chemical reactions; monitoring physiological indicators (HR, oxygen saturation) and abiotic environmental factors. Experimental results demonstrated a significant advantage of DMCs over traditional methods: The coefficient of professional knowledge acquisition in the experimental group (EG) increased by 19,7%. Readiness for independent research activity and interpretation of complex graphical data rose by 26,4%. The motivation level for scientific inquiry among participants increased by 17,1%. The implementation of DMCs in university research groups helps overcome the abstract nature of science concepts and transforms the student's role from a passive recipient into an active researcher-analyst. Systematic work with digital sensors ensures a holistic scientific worldview and enhances the competitiveness of future teachers in a modern digital school.
