“…The Turkish curriculum suggests teachers use appropriate manipulatives and technology where applicable, leaving it as optional, as Erbilgin (2017) presumed, because those resources might not be available in all schools. Several studies from Turkey (Altinyelken, 2011;Altinyelken & Sozeri, 2017) have reported that a teacher's decision to incorporate particular curriculum aspects (in this case, the use of mathematical tools, including both representational and physical) into their classroom practice is influenced by several dimensions in education, including their beliefs, interpretations of the pedagogical approaches, and classroom realities (Altinyelken & Sozeri, 2017) as well as the prevalence of national high-stakes testing (Ozpolat, 2013).
