EPISTEMOLOGICAL OBSTACLES IN COMING TO UNDERSTAND THE LIMIT OF A FUNCTION AT UNDERGRADUATE LEVEL: A CASE FROM THE NATIONAL UNIVERSITY OF LESOTHO
- 198 Downloads
This article reports on part of a doctoral study in which epistemological obstacles that mathematics students at undergraduate level encounter in coming to understand the limit of functions in different modes of representation were investigated. A group of mathematics students at undergraduate level at the National University of Lesotho was the sample for the study. Empirical data were collected using questionnaires and interviews.
