This study aims to address the need to support the improvement of teaching practices of South African mathematics teachers. Both international and South African literature suggest that orchestrating whole class discussion by using the practice of revoicing, can support learner appropriation of mathematical discourse, and that it is particularly suited to multilingual environments. Given the staying power of traditional style teaching, this study explores revoicing as a feedback practice within this style of Initiate, Respond, Evaluate/ Feedback (IRE/F) format. Two grade 6 mathematics teachers in Johannesburg were interviewed and their lessons were observed, filmed and analysed using a detailed coding instrument. The teachers were found to be giving as much revoicing as non-revoicing feedback to their learners and that revoicing was used in limited ways, mostly different to those suggested in the literature and not always productively. Key categories of revoicing seen in this study were repeating to affirm learners as well as rephrasing into mathematical language and funnelling learners towards correct answers. The contribution of this research to the field has been to expose the different ways in which two South African teachers are already using the practice of revoicing, in order to see the potential for further research and improved practice.

Det undersökta området för denna studie behandlar klassrumsdiskussioner kring ett matematiskt innehåll utförda av elever i två klasser i år 6 som är nivågrupperade. Dessa två grupper består övervägande av lågpresterande respektive övervägande av högpresterande elever. Denna studie är ett undervisningsförsök med syfte att undersöka hur metoden som innefattar medvetna strategier i form av ”talk-moves” fungerar i dessa klassrumsdiskussioner. Skillnader och likheter under nämnda klassrumsdiskussioner jämförs mellan nämnda grupper. Studien är begränsad till att behandla samspelet mellan elevernas prat och tankar under berörda klassrumsdiskussioner. Till största delen består metoden som används för denna studie av videoinspelningar som sedan observerades. Dessa ”talk-moves” innebär att läraren får verktyg att bjuda in samtliga elever att delta i klassrumsdiskussioner.  Läraren kan också använda dessa verktyg till att möjliggöra för eleverna att bygga sin egen kunskap. Detta innebär i sin tur en möjlighet för eleverna att komma förbi utantillinlärning. / The area of subject of this study is classroom discussions in mathematics. The purpose of the study is to investigate how the method called “talk-moves” functions in two ability grouped classes of year six. Each group consists mainly of low-level ability students and high-level ability students. During these clasroom discussions differencies and similarities are compared between these two groups. The limitation of the study consists of the connections between the students´ talk and thoughts. The main part of the method of this study are videorecordings which were later observed. The teacher is able to use “talk-moves”  as tools which are used to invite all students of the class to participate in mentioned classroom discussions. It is also possible for the teacher to use these tools to enable the students to build their own knowledge. This means in turn a possibility for the students to overcome learning by heart.

Over 20,000 Swedish lower high school students are currently learning mathematics in English but little research has been conducted in this area. This study looks into the question of how much second language learner training teachers teaching mathematics in English to Swedish speaking students have acquired and how many of those teachers are using effective teaching practices for second language learners. The study confirms earlier findings that report few teachers receive training in second language learning but indicates that some of the teaching practices shown to be effective with second language learners are being used in some Swedish schools / Mer än 20 000 högstadiet elever i Sverige har valt att lära sig matematik på engelska, men det finns väldigt lite forskning inom området. Detta arbete granskar hur mycket utbildning i andraspråksinlärning har lärare som undervisar matematik på engelska till svensktalande elever och hur många av de undervisnings-strategier som tidigare forskning har visat att vara effektiva används numera under matematiklektionerna på engelska? Arbetet bekräftar tidigare forskning, som visar att få lärare som undervisar matematik på engelska till svensktalande elever har fått utbildning i andraspråksinlärning, men den här forskningen visar att några av de effektiva strategierna numera används under matematiklektioner i vissa skolor. / <p>Matematik</p>
