In recent years, there has been a growing effort to deepen our understanding of the complexities and mechanisms involved in integrating technology into mathematics education. This pursuit has led to the emergence of various theoretical frameworks, among which the Structuring Features of Classroom Practice (SFCP) (Ruthven, 2009) stands out. This paper presents a thorough review of the SFCP framework and its fundamental components, with a particular emphasis on its utilisation in examining teachers' domain-specific classroom practices involving digital technology. Drawing upon data from a recent multiple case study, this paper aims to illustrate the adoption and operationalisation of the SFCP in analysing how secondary mathematics teachers integrate dynamic digital tools into their practices as they teach the mathematical domain of geometric similarity. By contributing to the testing and refinement of the SFCP, this paper advances our comprehension of this innovative yet promising framework. Additionally, it provides a demonstration of its practical application and offers a critical reflection on its utility in exploring teachers' everyday classroom practices involving technology for teaching specific mathematical concepts.
