  Preservice teachers’ and teacher educators’ views on multilingual school students’ mathematical learning possibilities have been researched in the last decade. However, there are limited studies on how language and cultural differences in mathematical argumentation can broaden mathematics education learning possibilities in teacher education. Using multilingual preservice teachers’ evaluations of examples of Grade 4 students’ multimodal mathematical argumentation, the influence of different cultures and languages is explored. In a teacher education workshop, preservice teachers seemed to use different evaluation criteria for Grade 4 students’ mathematical argumentation, depending on their home language and culture. Nevertheless, the teacher educator only made use of some differences in evaluation criteria to broaden understandings about how young students’ mathematical argumentation can be affected by language and cultural expectations. Consequently, there are implications for multilingual mathematics teacher education courses.

  In discussions about supporting students with language-diverse backgrounds, the use of different resources has been highlighted as important. Nevertheless, very little attention has focused on digital resources, even though these are often touted as valuable for all mathematics learners. By analysing interactions between students in grade 7 about measurement problems, it is possible to identify the kinds of support that Minecraft made available for students’ mathematical argumentation. The results show that experiences of using digital games at home and learning mathematics at school affected the possibilities that Minecraft made available, including what languages were supported.

  In this paper, interviews with teachers and preservice teachers are analysed to understand their views about using digital tools in mathematics classrooms, connected to language-diverse students': communication; potential for learning; and available identities. When digital tools were seen only as providing ways to utilise the home language so that existing mathematical knowledge could be used to complete tasks in the language of instruction, then language-diverse students' available identities were reduced to becoming like their non-immigrant peers. In contrast, when digital tools were considered as providing opportunities for utilising a wider range of their language resources, then preservice teachers broadened their views about language-diverse students' potentials for learning and available identities.

  Etter innføring av programmering i LK20 fikk matematikk som ett av flere fag, et særlig ansvar for opplæring i programmering. Det er behov for mer kunnskap om lærerstudenters tilnærming når de nå må lære programmering i matematikk. Utgangspunktet for studien er et arbeidskrav der studenter på 5. året (masterstudenter i matematikk, GLU1-7 og 5-10) skal løse et selvvalgt matematikkproblem med bruk av programmering og algoritmisk tenking. De blir bedt om å reflektere over arbeidsprosessen og over hva de lærte i prosessen om seg selv som problemløsere. Data er 15 skriftlige innleveringer som studentene har tillatt at vi brukersom data. Som teoretisk rammeverk tar vi utgangspunkt i posisjoneringsteori (Van Langenhove og Harré, 1998; Harré et al., 2009). I vår begynnende analyse finner vi at de fleste studentene beskriver seg som nybegynnere i programmering. Disse deler seg i to grupper; de som posisjonerer seg som nysgjerrige og utholdende, og de som posisjonerer seg som frustrerte og utålmodige i aktiviteten. Selv om oppdraget var å løse et matematisk problem med programmering der målet var deres egen læring, posisjonerer de fleste studentene seg som framtidige lærere og bruker dette både til å begrunne valg av oppgaver, vanskegrad de velger, og når de reflekterer over «nytteverdien» av aktiviteten. Resultatene vil bli brukt for å videreutvikle undervisningen i programmering i matematikk for lærerstudenter.

  Abstract. This paper aims to explore how two teachers in upper secondary schools engaged with the process of implementing programming in mathematics after a new curriculum was introduced. Bakhtin´s dialogism with tensions between voices is used to understand the tension as a potential for learning. We are also inspired by Brennan’s tensions, which describe what professional development designers have to balance when designing teacher courses in programming. The data are interviews with two teachers after their first year of teaching programming in mathematics. The results demonstrate contradictions and tensions between voices from teachers, learners, and authorities and between actual and aspirational. This can provide insights that can be useful for educators and policy-makers to better support programming integration into mathematics courses.

  The study presented in this paper focuses on primary school teachers engaging with the Body Mass Index (BMI) as part of a university course. The BMI is seen as an example of prescriptive modelling where mathematics is used to keep track of the obesity phenomenon. Four categories are developed to characterize the teachers’ discussions: the mathematical aspects of the BMI formula, meta-validation, the consequences of the use of the BMI and other indices in society, as well as on their teachability in the classroom. The results can contribute to developing an understanding of prescriptive modelling processes from a critical perspective.
