dc.description.abstractThis study addressed the inherent quandary of misconceptions that impacts on performance as reported in the National Diagnostic Report of the learner performance in the National Senior Certificate (NSC) 2011 examinations. In order to gain insights into learner performance, Sfard’s (2008) commognitive framework was used as a theoretical lens to examine learners’ mathematical thinking about functions. This study first described components of function concept from a constructivist perspective and further redescribed these in discursive terms i.e. from a focus on learners’ use of terminology to words/word use; from representations to visual mediators; from competencies to routines; and from concept definition to endorsed narratives. Data was collected through written tests and interviews of Grade 11 learners in one of the multilingual schools in one Province in South Africa. The research approach was first quantitative .Twenty six learners were given tasks involving functions that would highlight their errors. The study then moved to an interpretive qualitative approach based on Sfard’s commognitive theory. The qualitative study had five participants. A multiple methods strategy of data collection was employed during this stage: learners’ interview transcripts, written work and researcher’s field notes. The quantitative study confirms that learners were making errors on functions. The analysis of the qualitative study revealed that learners’ discourse included a combination of colloquial and mathematical discourse as expected. Interestingly, while all the features of mathematical discourse were present in learners’ mathematical discourse, their routines and words were linked to errors.en_ZA
