Özet:

This paper addresses the ways that real objects are important for conceptual development and understanding of pi. While using real objects in teaching and learning pi with nine university pre-service teachers (PSTs), the teaching and learning processes were framed under the lens of social constructivist perspective (Vygotsky, 1978). Individual PSTs constructed mathematics and elaborated their understanding of mathematics through social interactions with more knowledgeable others. It was found that PSTs: learned mathematics by doing, interpreted a concept in multiple ways, learned mathematics relationally, learned how to develop the meaning of pi and its value, and real objects helped PSTs eliminate systematic errors.The findings have implications in teaching and learning mathematics, including PSTs can learn how to use real objects in teaching and learning mathematics in their own classrooms.
