Phonological processing skills, including phonological awareness, phonological working memory and rapid automatised naming, are widely accepted as essential building blocks of early literacy development (Wagner and Torgesen 1987, 192). Despite this, no previous research has investigated the long-term contribution of phonological processing skills to literacy acquisition in Northern Sotho-English emergent bilingual children. Perhaps as a result of this knowledge gap, the South Africa curriculum provides no systematic guidance on how these foundational skills should be taught in Northern Sotho. There is also little understanding of how these skills might transfer between Northern Sotho and English. This longitudinal study investigated the contribution of various phonological processing abilities to literacy acquisition in Northern Sotho children and examined the cross-linguistic relationship between these skills. Using both standardised and self-made assessments, data was collected in both Northern Sotho and English from two groups of learners (134 in total) in the foundation phase. One group used Northern Sotho as Language of Learning and Teaching, while the other group used English as Language of Learning and Teaching. Data were collected at three points (beginning of Grade 2, end of Grade 2 and end of Grade 3). Statistical analysis of the data suggests that phonological awareness and rapid automatised naming are the strongest long-term predictors of literacy acquisition in Northern Sotho and in English in this population. Phonological awareness was also the strongest cross-linguistic predictor of literacy skills. Furthermore, the results provided evidence that learners were (over)using one linguistic grain size (syllables) to facilitate reading in both Northern Sotho and in English, but that phoneme awareness predicted literacy outcomes better than syllable awareness. Learners showed significant progress on most skills from the beginning of Grade 2 to the end of Grade 2. A few significant group differences were observed, but the findings did not suggest substantial mother tongue advantages in the overall development of learners' cognitive-linguistic and literacy skills. The study provides evidence of the importance of teaching phonological awareness at the phoneme level in both Northern Sotho and English. The implication is that language-specific phonological and orthographic features of Southern African Bantu languages must be considered in the South African curriculum and in African reading methodologies.

Fonologiese verwerkingsvaardighede, insluitende fonologiese bewussyn, fonologiese werkgeheue en snelle geoutomatiseerde benaming word algemeen beskou as noodsaaklike boustene in vroeë geletterdheidsontwikkeling. Ten spyte hiervan is daar tot dusvêr geen navorsing verrig om die longitudinale effek van fonologiese verwerkingsvaardighede op die ontwikkeling van geletterdheid in Noord-Sotho - Engels ontluikende tweetalige kinders te ondersoek nie. Moontlik as gevolg van hierdie kennisgaping is daar tans geen sistematiese riglyne in die Suid-Afrikaanse kurrikulum wat op die instruksie van hierdie fundamentele vaardighede in Noord-Sotho fokus nie. Daar is ook weining insig in hoe (indien enigsins) hierdie vaardighede van Noord-Sotho na Engels (en omgekeerd) oorgedra word. Hierdie longitudinale studie se hoofdoel is om die rol van verskeie fonologiese verwerkingsvaardighede in die verwerwing van geletterdheid in Noord-Sotho vas te stel. ’n Sekondêre doel is om die aard van die wedersydse verband tussen hierdie vaardighede in Noord-Sotho en in Engels vas te stel. Data vir hierdie studie is van twee groepe Noord-Sotho leerders (134 in totaal) in die grondslagfase gekollekteer deur middel van sowel gestandardiseerde as selfgemaakte toetse. Groep 1 se onderrigtaal was Noord-Sotho, terwyl Groep 2 se onderrigtaal Engels was. Data is op drie punte gekollekteer (aan die begin van Graad 2, aan die einde van Graad 2 en aan einde van Graad 3). Statistiese analise van die data suggereer dat fonologiese bewussyn en snelle geoutomatiseerde benaming die beste langtermyn voorspellers is van geletterdheidsverwerwing in sowel Noord-Sotho as in Engels in hierdie populasie. Fonologiese bewussyn was ook die beste kruislinguïstiese voorspeller van geletterdheidsvaardighede. Die resultate dui verder daarop dat leerders een spesifieke linguïstiese deeltjie (naamlik die lettergreep) oorgebruik om lees in sowel Noord-Sotho as Engels te fasiliteer – dit ondanks die feit dat foneembewussyn ‘n beter voorspeller van geletterdheidsuitkomste was as lettergreepbewussyn. Leerders in albei groepe het beduidende vordering getoon in meeste van die vaardighede wat getoets is, maar die oorkoepelende resultate het nie die idee van ‘n moerdertaalonderrigvoordeel ondersteun nie. Hierdie studie beklemtoon die belang van sistematiese instruksie van fonologiese bewussyn op die foneemvlak in sowel Noord-Sotho as Engels in die grondslagfase. Die implikasie is dat die taalspesifieke fonologiese en ortografiese kenmerke van Suidelike Bantoetale in ag geneem moet word in die Suid-Afrikaanse kurrikulum en in leesmetodologieë van Afrika-tale.
