Abstract
Abstract : This study explored students’ usage of an online interactive program which was designed to improve their mastery of mathematical procedures. The aim was to examine students’ mastery of mathematical procedures through repetitive practice of procedures relating to simplification of exponents. A purposive sample of 42 first - year extended engineering students was selected. This quantitative and qualitative study was conducted in one of South Africa’s public universities located in the Gauteng province. Sources of data for the study included students’ online reports and an open-ended questionnaire. The findings indicated that some students made use of the program successfully by showing mastery of mathematical procedures. However, other students only attempted exercises requiring skills with which they were already familiar and comfortable.
