  In this paper we investigate how two teachers in upper secondary schools engaged with the process of implementing programming in mathematics after a new curriculum was introduced. Based on Bakhtin’s dialogism and his theory about tensions between voices as a potential for learning, we seek to explore the teachers’ struggle when introducing programming. We are also inspired by Brennan’s identified tensions, which describe what professional development designers must 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, authorities and between what their aspirations were when they started teaching programming and what they experienced. This provides insights that can be useful for educators and policymakers to better support programming integration into mathematics courses.

• Rangnes, Toril Eskeland; Jemai, Khaled Ben Latief & Maugesten, Marianne (2023). Lærerstudenters refleksjoner og posisjonering i arbeid med programmering . Show summary

  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.
