Fostering an intimate interplay between research and practice: Danish ”maths counsellors” for upper secondary school
Uffe Thomas Jankvist and Mogens Niss
Abstract
The gap between research and practice is a wellknown problem (and topic) in educational research, and not least in mathematics education research. This empirically based article discusses the effects of a particular attempt to foster a closer connection between research and practice by involving mathematics education research findings in the activities of selected Danish upper secondary school mathematics teachers, who (have) take(n) part in a researchbased socalled ”maths counsellors” inservice teacher programme. A key aspect of the programme is to make the activation of research findings a mere necessity for significant aspects of the maths counsellors’ practice. To illustrate the teachers’ researchbased work, the article presents six characteristic examples from the implementation of the programme, i.e. authentic examples of how prospective maths counsellors have identified students with mathematics specific learning difficulties, have diagnosed the nature of these difficulties, and how they have designed interventions to help the students overcome them. A discussion of how these activities draw upon and are grounded in mathematics education research findings serve as a basis for evaluating the ”model” behind this further education programme.Uffe Thomas Jankvist

Guidelines for utilizing affordances of dynamic geometry environments to support development of reasoning competency
Ingi Heinesen Højsted
Abstract
This article reports on guidelines developed based on an extensive research literature review investigating the potentials of dynamic geometry environments (DGEs) when the educational aim is to support students’ development of mathematical reasoning competency. Four types of potentials were identified – feedback, dragging, measuring, and tracing – and used in three dimensions of guidelines: students’ cognition, task design, and the role of the teacher. Using constructs from the Instrumental approach, the Theory of semiotic mediation, and the van Hiele model of levels, affordances and guidelines are elaborated upon and their potentials for reasoning competency are analyzed.Ingi Heinesen Højsted

Conservative and transformative changes in algebra in Swedish lower secondary textbooks 1995–2015
Kristina Palm Kaplan and Johan Prytz
Abstract
The present study examines textbook algebra tasks in an attempt to understand how textbooks change in a reform of lower secondary school algebra. Changes in 1557 textbook tasks for year 8 are described in terms of algebraic activities and school algebra discourses. The tasks were taken from textbooks published before and after a new syllabus was introduced in Sweden in 2011. The results show that the new syllabus’ focus on mathematical competences was not stressed in the textbooks and that the greatest change was an increase in word problems connected to everyday situations. It is suggested that, in this reform, textbooks have been conservative and transformative in relation to the syllabus.Kristina Palm Kaplan

Swedish primary teacher education students’ perspectives on linear equations
Paul Andrews
Abstract
Linear equations, connecting arithmetic to the symbolism of formal mathematics, represent a key topic of mathematics. However, the understanding primary teacher education students bring to their studies has been rarely examined. In this study, students were invited to explain in writing how an unannotated solution to x + 5 = 4x – 1 had been conceptualised by the hidden solver. Data, coded against an iteratively derived framework, showed that most students were familiar with linear equations, able to articulate an objective for equation solving and offer solution strategies, typically based on either doing the same to both sides, swapping the side swapping the sign or both.Paul Andrews
Paul Andrews is a Professor of Mathematics Education at Stockholm University. His research interests are typically focused on comparative analyses of mathematics didactics and participant, both teacher and student, beliefs. Currently he is the director of a Swedish Research Councilfunded project on the development of foundational number sense in year one children in England and Sweden. His methodological and theoretical standpoints are varied and determined by the research questions he is pursuing at the time.Skapad: 20200630 kl. 09:57

Potentialer og begrænsninger ved anvendelse af lærebøger i matematikundervisningen: resultater fra et systematisk review
Natasja Steen, Matilde Stenhøj Madsen and Tomas Højgaard
Sammendrag
Denne artikel sammenfatter et kvalitativt, systematisk review af hvilke potentialer og begrænsninger der kan identificeres ved anvendelse af lærebøger i matematikundervisningen. Første del af artiklen beskriver den metodiske tilgang og afsluttes med et geografisk og tidsmæssigt overblik over forskningsfeltet. I anden del af artiklen præsenteres anvendelsen af begrebskort som et analyseredskab til at afdække sammenhænge i temaerne i den udvalgte litteratur. Resultatet af reviewet præsenteres som et oversigtsskema over de 59 inkluderede kilder. Disse kilder fordeler sig indenfor ti temaer der overordnet kan placeres i fire kategorier: ”lærebogsbegrebet”, ”lærebogen og eleverne”, ”lærebogen og curriculum” samt ”lærebogen og lærerne”. Disse kategorier udtrykker relationer lærebogen indgår i. Tredje del af artiklen beskriver eksempler på fund indenfor de fire kategorier og går tættere på kvalitative analyser i tre af disse temaer herunder et bud på en definition af begrebet ”lærebog”.Abstract
In this article we present a qualitative systematic review guided by the question: Which potentials and limitations of using textbooks in mathematics teaching can we identify?
Firstly, we present the methological approach and provide an overview of the literature with regard to geographic origin and year of publication. Secondly, we describe how we used a concept map as an analytic tool to illustrate connections of the themes in the literature. In this part we also present a descriptive review of 59 included sources, resulting in ten themes sorted in four categories: ”the textbook”, ”the textbook and the students”, ”the textbook and the curriculum” and ”the textbook and the teacher”. These categories express relations that the textbooks are part of. Thirdly, we present some of the findings in the four themes and take a deeper look at the qualitative analysis of three of these themes including a suggested definition of the concept ”textbook”.Natasja Steen

Understanding the relationship between length and area when changing the size of a twodimensional geometric figure
Jenny Svanteson Wester and Angelika Kullberg
Abstract
When scaling up or down twodimensional geometric figures, students tend to believe that if the lengths are doubled, the area is doubled as well. Although a lot of effort has been made to study and overcome this illusion of linearity, previous research reports that the illusion often remains after teaching. We add to this research by studying students’ experiences of the relationship between change in length and change in area when enlarging or reducing twodimensional geometric figures, identified in a learning study aimed at finding powerful ways of teaching scale to 14yearold students. The aim of this study is to contribute to a deeper understanding of students’ experiences of the relationship and how it can be taught. Teaching the change in length and the change in area simultaneously was found to be one key to students’ learning.Jenny Svanteson Wester

Kystfiskermatematikk og skolematematikk: to ulike perspektiver på hva ei méd er
Anne Birgitte Fyhn og Håkon Robertsen
Sammendrag
Kystens begrep méd er sentralt for blant annet å finne frem på havet og for å lokalisere fiskeplasser. En tradisjonell euklidsk beskrivelse går ut på at ei méd er ei rett linje gitt ved to punkter. Kystens folk har imidlertid utviklet sitt eget funksjonelle språk knyttet til begrepet méd. Der skolematematikken refererer til begreper fra euklidsk geometri, har kystfiskerne utviklet egne begreper og egen terminologi. Artikkelen bidrar til å synliggjøre matematikk i denne delen av vår immaterielle kulturarv. Vi belyser hvordan forskjeller mellom nordnorske kystfiskeres matematikk og skolematematikk kommer til uttrykk gjennom språk og kulturell praksis. Kystfiskernes kontekstavhengige matematikk bruker få ord, men språket er like presist som skolematematikkens mere omstendelige formuleringer.Abstract
The coastal people’s concept med is central for finding one’s way at sea and for locating places to fish. A traditional Euclidean description is that a med is a straight line given by two points. The coastal people have developed their own functional language related the concept med. Where school mathematics refer to concepts from Euclidean geometry, the coastal people have developed their own concepts and their own terminology. The paper contributes to making visible some mathematics in this part of our intangible cultural heritage. We enlighten how differences between coastal fishermen’s mathematics and school mathematics is expressed by language and cultural practice. The fishermen’s mathematics is intertwined with context and use few words. Their language is as precise as the formulations in school mathematics.Anne Birgitte Fyhn

Exploring engineering students’ participation in flipped mathematics classroom: a discursive approach
Helge Fredriksen and Said Hadjerrouit
Abstract
This paper explores firstyear engineering students’ participation in flipped mathematics classroom. The work uses Sfard’s commognitive framework both as a lens for conceptualizing learning as participation in mathematical discourse and as a methodology for analysing the data generated by the activities that build the mathematical discourse. Data was collected mainly by video recording of classroom activities of firstyear engineering students enrolled in several mathematics courses at a Norwegian university in 2016/2017. The aim of the study is to add to the lack of research on participation in flipped mathematics classrooms at the university level. The paper argues that engagement in the videos outofclass enhances students’ participation in the mathematical discourse. The commognitive analysis comparing outofclass videos and inclass activities show that there are indications of student learning through expansion of the discourse in the videos and enhanced participation in mathematical activities.Helge Fredriksen

Meanings of decisionmaking in probability and statistics: comparing Chilean and Danish upper secondary school curricula
Raimundo Elicer
Abstract
In this article I investigate the roles given to decisionmaking in probability and statistics upper secondary school curriculum, in a comparative study between Chile and Denmark. Drawing upon Fairclough’s model for Critical discourse analysis, I analyse selected official curricular texts as examples of broader discursive practices. In particular, I focus on the positioning of social actors and legitimation strategies. Present discourses position students as active decision makers, though in the Chilean case this is only evident in more recent texts. The teaching and learning of probability and statistics are legitimised through the appeal to political, professional and educational authorities, and through narratives of necessity for rational, grounded, evidencebased decisions. In this aspect Danish texts are more open to complex social and political decision processes. The analysis illustrates a common search for linking mathematics education to democratic involvement in social and political decisionmaking, but failing to specify the relevance of probability and statistics beyond the individual psychological scope.Raimundo Elicer

Avtryck i problemlösnings undervisning – en fenomenografisk studie
Camilla Sjölander Nordin
Sammendrag
I denna artikel beskrivs hur nio lärare för åk 4–6 och 7–9 erfar sin problemlösningsundervisning och kollegiala lärande två år efter att de deltagit i Matematiklyftet, som var en nationell fortbildningssatsning i Sverige under 2012–2016. Studien tar en fenomenografisk ansats, och visar en variation i hur lärare erfar sin problemlösningsundervisning beroende på om de fortsatt att arbeta i en organiserad form av kollegialt lärande eller inte. Bilden studien ger är att det inte främst är lärarnas ämnesdidaktiska kunskaper, som påverkar hur de erfar problemlösningsundervisningen, utan att det istället är de organisatoriska faktorerna som spelar stor roll.Abstract
For teachers in Sweden an extensive continuing educational training in mathematics didactics has been conducted. 35 000 teachers participated in this Boost for mathematics (Matematiklyftet in Swedish) (Ramböll, 2016). This phenomenological study describes how teachers for grades 4–6 and 7–9 experience their own teaching in problem solving two years after attending a Boost for mathematics. The study is based on interviews with the teachers. The outcome of the study shows the teachers’ thoughts on teaching of problem solving education, the skills of problem solving and collegial learning.
Teachers’ learning is looked upon as a natural and expected part of the teachers (Clarce & Hollingworth, 2002). For teachers’ learning the result shows that those who no longer take part in collegial learning, today create their own forms of organization and that they to some extent take support of the five practices (Stein et al.,2008), but in that case mainly to support the structure of the lesson. Teachers who continue collegial learning also continue teaching based on the Boost for mathematics model, but in some cases there are elements with certain qualitative alterations. In their teaching of problem solving the result shows that these teachers have a critical attitude towards the contents of the education as well as the form of the teaching and the teachers use the five practices in their teaching. All teachers look upon it as a challenge to work with the skills of problem solving and the result shows that teachers to a very small extent allow the students to train their ability to formulate their own problems. Ellström (2005) believes that a continuing education initiative for a year cannot be perceived as a solution. The longterm effects are lacking and practice needs to be constantly maintained and developed.Camilla Sjölander Nordin

Algebra teachers’ questions and quandaries – Swedish and Finnish algebra teachers discussing practice
Cecilia Kilhamn and AnnSofi RöjLindberg
Abstract
Taking the teachers’ own practices as a point of departure, this study investigates what areas of mathematical knowledge algebra teachers brought up in collegial discussions and how they used their knowledge in acts of decompressing, trimming and bridging. The discussions centered around aspects of teaching and learning school algebra previously shown to be problematic, but gave rise to mathematical quandaries, revealing gaps in the teachers’ own understanding of the mathematical content. The study implies that the ability to unpack a mathematical concept is essential in algebra teaching and that teachers may need external input concerning mathematical knowledge to enable development in pedagogical content knowledge.Cecilia Kilhamn

Algebraic thinking and level of generalisation: students’ experiencing of comparisons of quantities
Helena Eriksson
Abstract
This article explores grade 1 students’ different ways of experiencing quantity comparisons after participating in teaching designed as a learning activity using tasks from the Davydov curriculum. A phenomenographic analysis generated three hierarchical ways of experiencing comparisons: counting numerically, relating quantities, and conserving relationships. The first category comprises arithmetic ways of thinking, whereas the second and third categories comprise algebraic ways of thinking. Algebraic thinking was identified as reflections on relationships between quantities at different levels of generalisation. The implications of these results in relation learning activity theory are discussed.Helena Eriksson
Helena Eriksson is a PhD student at the Department of Mathematics and Science Education, Stockholm university. Her PhDproject concerns learning activity as a framework for designing teaching as well as a framework for research.

Artikelns syfte är att beskriva och analysera vad i olika lektionssekvenser som skapar förutsättningar för att elever ska engageras i ett algebraiskt arbete och därmed urskiljer kritiska aspekter. Artikeln bygger på data från tre forskningslektioner i vilka lärandeverksamhet (learning activity) tillsammans med Radfords arbete om mönstergeneraliseringar har utgjort teoretiska utgångspunkter. I analysen har didaktiska principer från lärandeverksamhet samt kritiska aspekter gällande att uttrycka och argumentera för mönstergeneraliseringar fungerat som analysredskap. Resultatet kan bidra till att fördjupa förståelsen gällande på vilka sätt principerna från lärandeverksamhet kan stödja ett etablerande och upprätthållande av ett algebraiskt arbete och därmed möjliggöra för elevers urskiljande av kritiska aspekter.Abstract
The aim of the article is to describe and analyze what in different lesson sequences that creates the conditions for students to be involved in algebraic work and thereby distinguish critical aspects. The article is based on data from three research lessons in which Learning activity together with Radford’s work on pattern generalizations were theoretical starting points. In the analysis, didactic principles of Learning activity along with a few identified critical aspects regarding the ability to express and justify algebraic generalizations served as analytical tools. The result can contribute to deepened understanding of the ways the principles can support the establishment and maintenance of algebraic work enabling students to distinguish critical aspects.Jenny Fred

Developing a frame for analysing different meanings of the concept of variable mediated by tasks in elementaryschool mathematics textbooks
AnnaMaija Partanen and Pieti Tolvanen
Abstract
Pupils’ studies in arithmetic can support the development of their algebraic thinking if arithmetic is taken as a starting point for generalising in sensemaking discussions. One of the most prominent concepts in algebra is that of the variable, which can have many different meanings, depending on its context. In this paper, we develop a frame for content analysis of tasks in elementaryschool mathematics textbooks. New categories for the meaning of variable are added to previous summaries, based on the literature review and the analysis. The developed frame can be used for analysing curricular materials, especially at the elementaryschool level.AnnaMaija Partanen

Finnish students’ flexibility and its relation to speed and accuracy in equation solving
Peter Hästö and Riikka Palkki
Abstract
A total of 266 Finnish students participated in a flexible equation solving test. By flexibility we understand the knowledge of multiple strategies and ability to choose the most mathematically appropriate strategy for a given task. Here we focus on the first aspect, namely knowledge of appropriate alternative, socalled innovative strategies. The test measured students’ capacity and inclination for producing innovative strategies. We consider the relationship between these measures and students’ speed and accuracy in solving equations. We find that students with high capacity for innovation have high speed and accuracy. On the other hand, some low capacity students had high speed or accuracy whereas others had low. Inclination for innovation is not related to speed or accuracy.Peter Hästö

Tilgange til tidlig algebra
Thomas Kaas
Sammendrag
Undervisning af 6–12 årige i algebra og algebraisk tænkning har under betegnelsen ”tidlig algebra” gradvist etableret sig som forskningsområde og undervisningspraksis i et stigende antal lande. På basis af et hermeneutisk inspireret litteraturstudie karakteriserer denne artikel de indholdsmæssige tilgange til undervisning i tidlig algebra, som forskningslitteratur i perioden 1995–2017 giver. Analysen har resulteret i et rammeværk for tilgange til tidlig algebraundervisning, som præsenteres og diskuteres. Artiklen konkluderer bl.a., at undervisning i tidlig algebra typisk tager afsæt i elevers arbejde med tal, kvantiteter og/eller funktionelle sammenhænge, og at elevers algebraiske tænkning søges udviklet gennem aktiviteter, der enten har opdagelser af generelle egenskaber og egenskaber eller ræsonnementer vedrørende ukendte talstørrelser som fokus. Forskelle mellem de forskellige tilgange vedrører desuden den rolle, som repræsentationer og kontekster har i undervisningen.Abstract
Teaching of 6–12 year old students in algebra and algebraic thinking has gradually become established as a research area and teaching practice in an increasing number of countries, under the term early algebra. This article presents a hermeneutically inspired review that was conducted to characterize and discus content approaches to early algebra teaching provided by the research literature in the period 1995–2017. The analysis of the included literature has resulted in a framework for approaches to early algebra teaching, which is presented and discussed.
The article concludes that early algebra teaching typically takes its starting point in students’ work on numbers, quantities and / or functional contexts, and that students’ algebraic thinking is taught through activities that have either identification of general relations and properties or reasoning with unknown quantities as focus. Differences between the different approaches relate also to the role of representations and contexts in the teaching.Thomas Kaas

University students’ general and specific beliefs about infinity, division by zero and denseness of the number line
Kristina Juter
Abstract
A study of university students’ beliefs about infinity and related concepts, e.g. division by zero and denseness of the number line, was conducted. The concepts were chosen for the students’ proven cognitive challenge in coping with them, and part of the study was to analyze individual beliefs of the different concepts in relation to each other. A questionnaire was designed to discover relationships between pre service teachers’ and technology students’ beliefs. Particular foci in the study were general and specific perspectives of the concepts and admission requirements for the programs. The results show incoherence with respect to general and specific representations of aspects concerning denseness of the number line, and also show that admission requirements are significant when it comes to validity of beliefs about division by zero.Kristina Juter
Kristina Juter is Professor of Mathematics education at Kristianstad Uni versity in Sweden.

Engaging children in mathematical discourse: a kindergarten teacher’s multimodal participation
Svanhild Breive
Abstract
This article reports from a case study which investigates a kindergarten teacher’s multimodal participation in a teachinglearning activity involving addition and counting. By multimodal participation the kindergarten teacher engages nine children (age 4.9–5.9) in mathematical discourse and supports their opportunities for learning. Implications for practice are that kindergarten teachers (and school teachers) can benefit from being consciously aware of the affects their bodily actions have on children’s mathematical reasoning and how they can engage children in mathematical discourse without having to ”teach” (i.e., tell) children mathematical concepts and relations. The article also considers how kindergarten teachers can prepare for a smooth transition to school by introducing children to mathematics through semistructured activities.Svanhild Breive

Authority in students’ peer collaboration in statistics: an empirical study based on inferentialism
Abdel Seidouvy, Ola Helenius and Maike Schindler
Abstract
Students’ peer collaboration efforts in mathematics and statistics is a topic that has increasingly gained attention in research. In any collaboration, authority relations play a role for how meaning is constituted: Whenever things are discussed and decisions are made, authority is involved in a sense that some arguments or persons may be more convincing and powerful than others. In this article, we investigate how authority changes dynamically in type and in distribution as groups of fifth grade students collaborate in data generation processes. We identify and categorize authority using an epistemological framework, which is based on the philosophical theory of inferentialism. The results show that the three different types of authority described in inferentialism are all identifiable in students’ collaborative work. We also find and categorize further types of authority connected to the statistics group work, some of which are hardly addressed in previous research.Abdel Seidouvy

Investigating the fit of a model for students’ understanding of fractions in a Norwegian context
Trond Stølen Gustavsen and Olav Gravir Imenes
Abstract
To capture the complexity of students’ understanding of fractions, a model linking partwhole to the subconstructs ratio, operator, quotient and measure has been proposed. We ask if this model is compatible with students’ achievements in a Norwegian context. Responses from 638 students were analysed using structural equation modelling (SEM), and a good fit of the model was obtained after removing the ratio subconstruct. In particular, partwhole is seen to be important for operator, quotient and measure. Using qualitative analysis of interviews, we found reasoning associated with ratio, with a weak link to the partwhole subconstruct.Trond Stølen Gustavsen

Literature review of mathematics teaching design for problem solving and reasoning
Johan Sidenvall
Abstract
To characterize teaching designs intended to enhance students’ problem solving and reasoning skills or to develop other mathematical competencies via problem solving and reasoning, a literature review was conducted of 26 articles published in seven topranked journals on mathematics education from 2000 to 2016. Teaching designs were characterized by a) the educational goals of the designs, b) the claims about how to reach these goals, and c) the empirical and theoretical arguments underlying these claims. Thematic analysis was used to analyze the retrieved articles. All but two studies had goals concerned with developing students’ mathematical competencies. The overarching ideas of the identified emergent claims regarding the achievement of stipulated goals, concerned scaffolding students’ learning and letting students construct their own mathematics. Four recurring theoretical arguments were found to support emergent claims: hypothetical learning trajectories, realistic mathematics education, theory of didactical situations and zone of proximal development.Johan Sidenvall

Development of algebraic thinking: opportunities offered by the Swedish curriculum and elementary mathematics textbooks
Kajsa Bråting, Lars Madej and Kirsti Hemmi
Abstract
In search of the reasons for Swedish students’ low achievement in algebra in international and national evaluations, we investigate how the development of algebraic thinking is addressed in the Swedish national mathematics curriculum and two widely used mathematics textbook series for grades 1–6 in Sweden. The analytical tool used is based on the classification of ”big ideas” which research has shown as important for developing pupils’ algebraic understanding in early school grades. The results show that functional thinking, expressions, and equations are well represented topics both in the curriculum and the textbooks; however generalized arithmetic is a topic that is poorly developed in both the curriculum and the textbooks.Kajsa Bråting

Studying concept elements as a way to trace students’ conceptual understanding
Annika Pettersson, Yvonne Liljekvist and Jorryt van Bommel
Abstract
The understanding of mathematical concepts has been described in terms of concept definition and concept image. We suggest an elaboration of these constructs, the concept element, to find a way to theoretically describe students’ understanding. The concept element construct was tested in a setting with students working with linear functions at the secondary school level. Our empirical findings reveal traces of students’ concept elements regarding linear functions. Some concept elements appeared early in the process while others appeared after a cognitive conflict (e.g. evoked by the task construction and setting). The detailed grid on which concept elements are defined was a useful tool, yielding new insights into students’ knowledge and understanding.Annika Pettersson

Abstract
This Nomad special issue provides eleven highly interesting insights into current research and development projects in mathematics education on multilingual and multicultural issues. It shows the diversity of approaches currently adopted in the Nordic Countries with an impressing richness of perspectives and ideas. I am grateful to have had the opportunity to read and discuss the papers carefully as I learned a lot. In this commentary, I compare and connect the papers with each other and the international state of research and to suggest some directions for further research and development. The commentary is structured in the following steps: Di erent implicit and explicit conceptualization of languages are identi ed in the articles ( rst section); di erent research approaches are summarized with a need to strengthen Design research (second section); and di erent instructional approaches for activating multiple language resources for mathematics learning and further enhancing both languages (third section).Susanne Prediger

When does a difference make a difference? Teaching about language diversity in mathematics teacher education
Andrea Eikset and Tamsin Meaney
Abstract
There has been little attention in mathematics education research about how to include issues to do with language diversity in teacher education. This paper describes the process used by two teacher educators to examine their own practices of linking multilingual perspectives to mathematics education in their work with preservice teachers. By systematically analysing their discussion about a threehour, mathematicsteachereducation workshop on proportional thinking, the teacher educators were able to identify a series of Discourses. They considered that these Discourses underlay their decision making about how language diversity could be raised with preservice teachers. The results highlight the complexity connected to raising language diversity issues in mathematics teacher education. For example, deciding what challenging content should be provided to preservice teachers is a ected by the need to develop relationships with them as well as managing their learning. Joint re ection by the teacher educators was needed to ensure that the aim of challenging preservice teachers about how to deal with language diversity issues in mathematics classrooms could be achieved.Andrea Eikset

Talking about mathematics in two languages: Can parental views inform the development of digital games for young children?
Troels Lange and Tamsin Meaney
Abstract
In this article, the results are presented from a survey of parents’ views about the digital games that their young multilingual children play. Previous research has indicated that parents struggled to describe how their children were learning from playing digital games. The results from this study indicate that parents could provide information about the digital games and the mathematical language they invoked. This information could be useful in developing playful, digital games that support multilingual children to talk about mathematics. The survey also provides insights into the followup qualitative research studies that are needed to support the development of new digital games.Troels Lange

Polish parents’ views on mathematics activities at home and in Swedish preschools
Dorota Lembrér
Abstract
This article describes the results of a digital survey of 41 Polish immigrant parents’ views on mathematics activities at home and at preschool as parents’ views potentially provide a range of perspectives on mathematics activities for young children. Parents were asked to describe and justify their views about how children engage with mathematical ideas and nominate activities that children engage in at home and at preschool. When parents justi ed their views about young children and mathematics, they tended to align themselves with the norms and values of the Swedish preschool curriculum. The ndings suggest that parents, like children, are socialised into Swedish preschools. However, this alignment could limit possibilities for broadening perspectives about mathematics education in preschool, which could be available by incorporating input from immigrant parents’ di erent cultural and linguistic backgrounds.Dorota Lembrér

I artikkelen belyser vi kulturelle og språklige utfordringer som kan oppstå når teoretiske begreper fra matematikkdidaktisk forskning oversettes til et språk og en kultur som er ernt fra språket og kulturen der begrepene ble utviklet. I samarbeid med forskere oversatte lærere ved Guovdageainnu nuoraidskuvla/Kautokeino ungdomsskole et matematikkdidaktisk rammeverk fra engelsk til nordsamisk. Vi fokuserer på oversetting av aktiviteten locating som inngår i rammeverket. Locating omfatter grunnlaget for elevers utvikling av romlig forståelse. Vi bidrar også til diskusjonen om hvorvidt hovedområdene i matematikklæreplanen skal utformes som verb eller substantiver.Abstract
In this article we enlighten cultural and linguistic challenges that may occur when concepts from mathematics education are translated into a language and a culture that is far from the language and the culture where the concepts were developed. In cooperation with researchers, teachers at Guovdageainnu nuoraidskuvla/Kautokeino lower secondary school translated a mathematics education framework into North Sámi. We focus on translations of the activity locating, which is part of this framework. Locating constitutes the basis for students’ development of spatial understanding. We also contribute to the discussion about whether the national mathematics curriculum’s content areas should be verbs or nouns.Anne Birgitte Fyhn

En registeranalyse af centrale matematiske begreber i en grønlandsk kontekst
Mette Hjelmborg and Ane Fleischer
Sammenfatning
Denne artikel beskriver resultaterne af en registeranalyse af grønlandske matematiske begreber. Fokus for analysen er de karakteristiske træk, der opstår når man genererer et matematisk register i et polysyntetisk sprog. Vores teoretiske ramme er faglige registre og registerkontinuum i et systemisk funktionelt lingvistisk perspektiv. Metodisk foretages dokumentanalyser, der mættes af interviewsvar fra semistrukturerede interviews. Vores analyse indikerer, at der som oftest benyttes samtlige tre teknikker når grønlandske matematiktermer genereres: omskrivninger, nominaliseringer og metaforer. Det matematiske register knytter sig dermed i høj grad og på mange og varierede måder til det grønlandske dagligdagssprog.Abstract
This article describes the results of an analysis of the mathematical register in Greenland concerning the characteristics for developing terms for mathematical concepts in a polysynthetic language. The theoretical frame is registers, register continuum with respect to systemic functional linguistic. The analysis indicates that three techniques (gerunding, circumlocutions, and metaphors) are used simultaneously when generating new terms in Greenlandic. The mathematical concepts in Greenlandic thereby have a direct link to everyday meanings of similar concepts.Mette Hjelmborg

Culturally based mathematics tasks: a framework for designing tasks from traditional Kven artefacts and knowledge
Hilja L. Huru, AnnaKaisa Räisänen and Anita Movik Simensen
Abstract
This article discusses mathematical and cultural task design to support minority and endangered languages and cultures. More precisely, we propose a theoretical framework to design mathematical tasks for language immersion in mathematics for Kven students. Drawing on previous studies, we suggest that traditional tools have the potential to support the learning of mathematics, language, and culture. One challenge for endangered languages and cultures is that the younger generations may have lost connections with their traditional language and culture. We argue that the older generations can mediate authentic aspects of Kven culture to students, which then become historicalcultural authentic (HiCuA) aspects.Hilja L. Huru

Newly and earlyimmigrated secondlanguage students’ knowledge of arithmetic syntax
Jöran Petersson
Abstract
The present study investigated how 259 Swedish, grade 9 students, of whom 90 had an immigrant background, achieved on twelve written test items in the content area of number. Four of the twelve test items required good knowledge of arithmetic syntax, such as when it was appropriate to apply orderofoperation rules and the associative and distributive laws of arithmetic operations. On these four test items, the mostrecently arrived students showed on average signi cantly more knowledge than the students who had immigrated when they were younger and had participated in Swedish schools for longer periods of time. The outcome suggests that these two groups of immigrant students in later school years should be considered as separate subcategories of secondlanguage students when it comes to teaching, assessment and research.Jöran Petersson

The language factor – what exactly is it? Bilingual speakers of Russian and Finnish solving mathematical tasks
Maria Ahlholm and Päivi PortaankorvaKoivisto
Abstract
A lack of knowledge of the language of instruction is often believed to be the main reason for low achievement among students with an immigrant background. We regard language as a tripartite unit comprising aspects of concept formation, pragmatic language usage and the linguistic form. In this theoretical framework, we report two case studies of bilingual, Russian and Finnish speaking students’ explanations of their procedures while solving mathematical tasks. The students’ linguistic processing varied in terms of conceptualization, pragmatic meaningmaking and grammatical form. In a bilingual context, the labelling of concepts and meaningmaking through argumentation are simultaneously processed in two languages.Maria Ahlholm

Developing mathematical reasoning by using questions in a multilingual mathematics classroom
Marie Sjöblom
Abstract
In this paper, students’ questions while working in small groups on mathematical problemsolving tasks are investigated. In order to improve students’ reasoning and communication abilities in mathematics, an intervention study was designed in a multilingual upper secondary mathematics classroom in Sweden. In their discussions students used Swedish, which was their second language and also the language of instruction. The changes in students’ ways of using questions across the three cycles of the intervention were analysed. The results showed how students over the cycles changed their ways of framing questions from looking for the correct answer towards clarifying other students’ meaning in order to understand each other’s reasoning. The implication from the study is that it is important to promote interactions between students rather than focusing on students’ need to develop their second language competencies.Marie Sjöblom

Identity formations as mathematical learners in the context of transition
Petra Svensson Källberg
Abstract
This paper explores the relation between discourses and identity formations as mathematical learners in a context of transition. The data consists of an interview with two 16 yearold immigrant girls, who were relocated when their school, in a multicultural and socioeconomically disadvantaged area in Sweden, was closed. The girls showed dynamic and unstable identities by drawing on di erent discourses. Social relational discourses, more than mathematical pedagogical discourses, governed their actions as learners of mathematics; enabling identities as noisy, unengaged, but able students in the old school, and as engaged and accepted, but also as strangers, in the new school.Petra Svensson Källberg

Fabrication of newlyarrived students as mathematical learners
Eva Norén and Petra Svensson Källberg
Abstract
As a response to recent laws on how to support newlyarrived students’ schooling, new policy texts have been released in Sweden. By analyzing policy texts we show how a particular kind of human, ”the newlyarrived student as a mathematical learner” is fabricated through discursive processes. We show how the policy texts are framed within an including discourse that encourages multiculingualism and views students’ mother tongue and backgrounds as resources. However, simultaneously the newlyarrived student is thought of, in a more excluding discourse, as being in need of rescue and as lacking the most valuable asset, the Swedish language.Eva Norén

Scrutinizing teacherlearner interactions on volume
Anita Tyskerud and Reidar Mosvold
Abstract
This study adds to research on volume and spatial reasoning by investigating teacherlearner interactions in the context of Lesson study. Our analysis illustrates how the mathematical object of volume is realized, and what metarules of discourse that can be observed over two iterations of a research lesson. The study unpacks the mathematical work of teaching volume in terms of discourse, and shows how an undesirable and unexpected result from the first research lesson can be attributed to the communicational work of teaching rather than to lack of skills among students.Anita Tyskerud

Læreres utbytte av kunnskap om hjernen
Jan Roksvold
Sammandrag
Konkrete klasseromsanvendelser av hjerneforskning har latt vente på seg. I denne oversiktsartikkelen undersøkes det potensielle utbyttet for lærerstudenter ved å kjenne til ulike temaer knytta til hjernens befatning med tall og aritmetikk – uavhengig av hvorvidt slike entilenanvendelser eksisterer eller kan eksistere. Av potensiell verdi for lærere framheves blant annet kunnskap om hvilke vanskeligheter et assosiativt minne forårsaker i forbindelse med aritmetiske tabeller. Med bakgrunn i moderne hjerneforskning belyses ei tallbehandling som kan deles opp i en medfødt ”tallsans” og et kultur og utdanningsavhengig eksakt tallsystem, hvordan ulike binæroperasjoner behandles på grunnleggende forskjellig vis av hjernen, og hvordan innlæringsstrategi kan påvirke lagringa av aritmetisk kunnskap. Temaer som barnets ”logaritmiske indre tallinje” og dyskalkuli blir også belyst. Jeg konkluderer med at denne typen kunnskap om hjernen vil utvide lærerstudentenes forståelse av det lærende barnet, og dermed kunne påvirke deres praksis.Abstract
Concrete applications of neuroscience to the classroom are yet to be confirmed. The topic of this research article is the potential gains to be had for trainee teachers in knowing about various topics concerning the brain’s processing of numbers and arithmetic – regardless of whether onetoone applications exist or can exist. Highlighted as potentially valuable to teachers, is knowledge about: the dichotomy between an inborn ”number sense” and a culturally and educationally dependant exact number system; how different binary operations are processed; how learning strategy can affect the encoding of arithmetic facts; the difficulties caused by an associative memory in relation to arithmetic tables; the child’s ”logarithmic inner number line”; dyscalculia, and the neuromyth pertaining to it. I conclude that this type of knowledge will expand trainee teachers’ understanding of the learning child, and thereby possibly in uence their practice.Jan Roksvold

Disciplinary competence descriptions for external use
Jens Højgaard Jensen and Uffe Thomas Jankvist
Abstract
The article addresses the need for competence descriptions of disciplines as a means for fostering more productive communication between different disciplines and between the disciplines and their surroundings. It is argued that the usual competence descriptions devised for use within a discipline itself, e.g. in relation to teaching and learning of the discipline – socalled competence descriptions for internal use – are not the best means to achieve this. The same is true for the general, nondisciplinary competence descriptions. Instead, specially devised disciplinary competence descriptions for external use are called for. Our main illustration is a competence description of mathematics for external use devised so that it can support the dialogue about justi cation of mathematics education between the discipline’s practitioners and its recipients. This description for external use is counterposed with one for internal use i.e. that of the Danish KOM project. It is also counterposed with a competence description for external use for physics, taking into account the different justification problem of physics education. Together these two descriptions showcase how competence descriptions of disciplines for external use may support interdisciplinary collaboration and division of labor in the educational system.Jens Højgaard Jensen

The gap between school mathematics and university mathematics: prospective mathematics teachers’ conceptions and mathematical thinking
Jani Hannula
Abstract
In Finland, both prospective and inservice mathematics teachers report a discontinuity between universitylevel mathematics and mathematics taught at comprehensive and secondary school. In this study, ten prospective mathematics teachers (PMTs) were interviewed to examine their conceptions of the nature of this gap as well as their mathematical thinking. The study’s findings support research that has revealed difficulties experienced by PMTs in the secondary–tertiary transition and in connecting formal and informal components of mathematical thinking. Additionally, the study provides new insight into PMTs’ conceptions of teacher knowledge, such as the relationship between knowledge of advanced mathematics and the knowledge needed in teaching situations. The findings offer guidelines for further studies that could help the development of mathematics teacher education.Jani Hannula
