Application of Biological Keys in Education: Methodological Frameworks and Case Studies

Abstract

This paper explores the application of simple biological keys in education, aimed at enhancing students' ability to identify plant species and understand basic botanical principles. The research was conducted in schools, where students used biological keys to identify various plant species through practical tasks. The results showed that the use of these keys significantly improved students' ability to correctly identify plants, while also fostering skills in critical thinking, analysis, and collaboration. Group work and hands-on experience enabled students to actively engage in the learning process, leading to better outcomes. Although the results were positive, the research also highlights the need for further development of botanical skills, as some students faced difficulties in accurate plant identification. This paper concludes that biological keys, with appropriate didactic support, can significantly improve botanical education and recommends their broader implementation in schools.
