The use of the mother tongue (MT) as a medium of instruction in schools is still a problematic subject of debate in South Africa and the continent at large. In most African countries, English remains the medium of instruction (MoI). This structured research sought to highlight the pros and cons of using mother tongue instruction in schools, specifically Northern Sotho, which is spoken by one of the ethnic groups in South Africa. Currently, in South Africa, children receive mother tongue education from grade one to three. In this study, the researcher argues that mother tongue should be used from grade one to twelve. For this study, the researcher relied on extant literature on mother tongue education. The concept of Cognitive Academic Language Proficiency (CALP) by Cummins (2001) was used to guide this study. The argument for mother tongue education is premised on the fact that it is crucial for the success and progress of children at school. As an example, studies have shown that children who are taught in their mother tongue such as Afrikaans and English, which remain the defacto mediums of instruction in the schools in South Africa, and French, German, Mandarin, etc. in other countries, excel in school and understand subjects such as Maths and Science better.
Ngangišano ya tšhomišo ya polelo ya gae bjalo ka polelo yeo e šomišwago go ruta dikolong e sa le taba ye bothata dinageng tše ntši le mo Afrika Borwa. Dikolong tše ntši mo dinageng tše, Seisemane ke leleme leo le sa šomišwago bjalo ka leleme la go ruta. Tlhamo ya nyakišišo ye e nyaka go gateletša bohlokwa bja go šomiša polelo ya gae bjalo ka polelo yeo e ka šomišwago dikolong, kudukudu Northern Sotho yeo e bolelwago ke ye nngwe ya dihlopha tša MaAfrika Borwa. Gonabjale mo Afrika Borwa, bana ba rutwa ka leleme la gae go tloga go mphato wa 1-3. Mo thutong ye, monyakišiši o nganga gore polelo ya gae e swanetše go šomišwa go tloga go mphato wa pele go fihlela go wa masomepedi. Thutong ye, monyakišiši o ipotile ka dingwalo tšeo di ngwadilwego ka ga thuto ya polelo ya gae. Kakanyo ya “Cognitive Academic Language Proficiency (CALP)” yeo e tlilego ka Cummins (2001) e tla šomišwa go tlhahla thuto ye. Ngangišano ka ga thuto ya leleme la gae e theilwe godimo ga nnete ya gore le bohlokwa kudukudu go katlego le tšwelopele ya bana sekolong. Bjalo ka mohlala, dithuto di bontšhitše gore bana bao ba rutwago ka leleme la gae bjalo ka leleme la SeAfrikaanse le Seisemane, ao e sa lego maleme a thuto dikolong mo Afrika Borwa, SeForentšhe, Sejeremane, SeMandarini bjalobjalo kua dinageng tše dingwe, ba dira mošomo wo mobotse sekolong gomme ba kwešiša dithuto tša go swana le Thutadipalo le Saense bokaone.
