Revisited Van Hiele’s Model of Geometry in the Light of NEP-2020

Abstract

Geometry holds an important position within the mathematics curriculum, constituting a substantial segment of Indian school education across all levels. It is also relevant in everyday life and intersects with other mathematical disciplines. Individuals’ understanding of geometry differs, indicating different cognitive processes and interpretive frameworks. There are various ways in which geometry instruction might be approached from a pedagogical perspective. Van Hiele investigated and proposed a significant method for classifying and assessing individuals’ understanding of geometry. This model/theory involves five levels of geometrical understanding, particularly in understanding geometrical shapes and structures. Furthermore, through exploration, models offer a comprehensive framework for understanding spatial cognition. Consequently, educators gain valuable insights into students’ geometric understanding levels. This understanding enables the development of instructional methods that support cognitive growth and nurture geometric reasoning skills. NEP-2020 envisions an educational framework that focuses on conceptual understanding and nurtures creativity, innovation, and problem-solving abilities among students, aligning with the overarching goals of Van Hiele’s theory. In this study, Van Hiele’s model has been revisited in light of the National Education Policy (NEP) 2020; the study suggested to modernising educational practices and adapting them to contemporary needs. The model’s components, including its levels of understanding, characteristics, and instructional phases, are aligned with NEP-2020 principles to propose a comprehensive approach to geometry education. Furthermore, it is recommended that educators be provided with professional development opportunities to deepen their understanding of Van Hiele’s theory and efficaciously incorporate it into their pedagogical practices. By adopting these recommendations, educational institutions can establish a more robust foundation for geometry education, equipping students with the requisite skills to navigate an increasingly complex and dynamic world.
