Dlamini, Betty; Rollnick, Marissa; Lotz, Sandra; Lubben, Fred – Research in Science Education, 2001
Reports on an investigation of the status of procedural knowledge in chemistry among students entering into bridging programs at two South African universities. Findings show that students overall tend to repeat in order to get a recurring reading. Very few students were able to use a line of best fit for a set of graphical data. Discusses…
