Introducing the Concept of Convergence of a Sequence in Secondary School

.
Educational Studies in Mathematics, 60 (1): 71--93 (September 2005)

Abstract

My purpose in this paper is to present a didactic tool – a set of specially designed problems and questions for discussion – that can help making students better aware of the various aspects of the formal notion of limit of a sequence. The didactic tool will be justified using results from my own and other authors' research on students' naïve or erroneous conceptions of limit of a sequence. ER -
