    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 three-hour, mathematics-teacher-education 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.

    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 follow-up qualitative research studies that are needed to support the development of new digital games.

    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.

    Bishop Sámegillii – utfordringer ved oversetting av matematikkdidaktisk fagterminologi

    Anne Birgitte Fyhn, Ellen J. Sara Eira, Ole Einar Hætta, Inga Anne Marit Juuso, Siv Ingrid Nordkild og Ellen Margrethe Skum

    Sammenfatning
    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.

    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.

    Culturally based mathematics tasks: a framework for designing tasks from traditional Kven artefacts and knowledge

    Hilja L. Huru, Anna-Kaisa 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 historical-cultural authentic (HiCuA) aspects.

    Newly- and early-immigrated second-language 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 order-of-operation rules and the associative and distributive laws of arithmetic operations. On these four test items, the most-recently 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 sub-categories of second-language students when it comes to teaching, assessment and research.

    The language factor – what exactly is it? Bilingual speakers of Russian and Finnish solving mathematical tasks

    Maria Ahlholm and Päivi Portaankorva-Koivisto

    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 meaning-making and grammatical form. In a bilingual context, the labelling of concepts and meaning-making through argumentation are simultaneously processed in two languages.

    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 problem-solving 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.

    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 year-old immigrant girls, who were relocated when their school, in a multicultural and socio-economically 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, un-engaged, but able students in the old school, and as engaged and accepted, but also as strangers, in the new school.

    Fabrication of newly-arrived students as mathematical learners

    Eva Norén and Petra Svensson Källberg

    Abstract
    As a response to recent laws on how to support newly-arrived students’ schooling, new policy texts have been released in Sweden. By analyzing policy texts we show how a particular kind of human, ”the newly-arrived 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 newly-arrived 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.

    Scrutinizing teacher-learner interactions on volume

    Anita Tyskerud and Reidar Mosvold

    Abstract
    This study adds to research on volume and spatial reasoning by investigating teacher-learner 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.

    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 en-til-en-anvendelser 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 one-to-one 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.

    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 – so-called competence descriptions for internal use – are not the best means to achieve this. The same is true for the general, non-disciplinary 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.

    The gap between school mathematics and university mathematics: prospective mathematics teachers’ conceptions and mathematical thinking

    Jani Hannula

    Abstract
    In Finland, both prospective and in-service mathematics teachers report a discontinuity between university-level 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.

    Discourses in school algebra: the textbooks’ different views on algebra and the positioning of students

    Kristina Palm Kaplan

    Abstract
    The purpose of this study is to understand the school algebra offered in Swedish mathematic textbooks for grade 8. Using a social semiotic perspective, textbook tasks are analysed with a method inspired by Systemic Functional Linguistics. Five school algebra discourses are identified: symbolic discourse, geometrical discourse, arithmetical discourse, (un)realistic discourse and the scientific discourse. It is argued that these offer different views on the nature of algebra and the positioning of students.

    Kristina Palm Kaplan
    Kristina Palm Kaplan is a doctoral student at Uppsala University since September 2014. The main research interests are mathematics and language, especially algebra and social semiotics.

    Preschoolers exercising mathematical competencies

    Anna Ida Säfström

    Abstract
    The mathematical ideas that emerge in children’s free and guided play can be both complex and sophisticated, and if they are linked to formal mathematics, they can be a powerful basis for mathematical development. To form such links, one needs knowledge of how children use and express these ideas. This is especially true in the intersection of arithmetic and geometry, where the intermingling of numerical and spatial concepts and skills is not yet fully understood. This study aims to gain understanding of children’s mathematical practices by describing the interplay of key mathematical ideas, and more specifically how young children exercise mathematical competencies in the intersection of early arithmetic and geometry. The results show that children can use spatial representations when reasoning about numbers, and that they are able to connect spatial and numerical structures. Furthermore, it is shown that children not only use and invent effective procedures, but also are able to explain, justify and evaluate such procedures.

    A model for the role of the physical environment in mathematics education

    Magnus Fahlström and Lovisa Sumpter

    Abstract
    In this paper, we develop an analytical tool for the role of the physical environment in mathematics education. We do this by extending the didactical triangle with the physical environment as a fourth actor and test it in a review of literature concerning the physical environment and mathematics education. We find that one role played by the physical environment, in relation to mathematical content, is to portray the content in focus, such as geometry and scale. When focusing on teachers, students, and the interaction between them, the role of the physical environment appears to be a precondition, either positive (enabling) or negative (hindering). Many of the findings are valid for education in general as well, such as the importance of building status.

    Stimulating critical mathematical discussions in teacher education: use of indices such as the BMI as entry points

    Suela Kacerja, Toril Eskeland Rangnes, Rune Herheim, Meinrad Pohl, Inger Elin Lilland and Ragnhild Hansen

    Abstract
    The main purpose of our research project is to gain insight into, and develop teaching on indices and their applications in society. In this paper, the focus is to present insights into teachers’ reflections when discussing the Body Mass Index (BMI). Skovsmose´s concept of mathemacy, and source criticism, are chosen as conceptual framework. The data analysed were collected in a numeracy across the curriculum class with practising teachers. The findings show that the practising teachers engaged in meaning making of the index formula, and they critically discussed how BMI is used in society and the role the BMI index can have in our lives. We gain insight into the potential of such an index for developing teachers’ awareness of the application of mathematics­ to the real world and the issues it raises, both for the teachers and for ourselves.

    Finnish entry-level students’ views of teacher knowledge and the characteristics of a good mathematics teacher

    Mervi A. Asikainen, Antti Viholainen, Mika Koponen and Pekka E. Hirvonen

    Abstract
    This paper reports a study of the views held by Finnish students at the start of their university studies concerning their understanding of the knowledge and characteristics of a good mathematics teacher. A total of 97 students following a basic university course responded to a questionnaire. The results showed that a knowledge of teaching mathematics was more often used to describe the good mathematics teacher than a knowledge of mathematics. According to the students’ views, mathematics teachers need to be able to take the level of understanding of individual students into account in their teaching. Good mathematics teachers were also considered to be skilled in explaining, simplifying and transforming mathematical contents for their students. A good mathematics teacher was often described by the respondents as a patient, clear, inspiring and consistent person. On the other hand, characteristics such as humorous, likeable, empathetic, or fair were seldom used in the students’ responses to describe a good mathematics teacher. Those respondents who planned to become teachers demonstrated a more learner-centred concept of a good mathematics teacher than did those who were aiming at some other subject specialist profession than that of teaching.

    A study of students’ concept images of inverse functions in Ireland and Sweden

    Sinéad Breen, Niclas Larson, Ann O’Shea and Kerstin Pettersson

    Abstract
    In this paper we focus on first-year university students’ conceptions of inverse function. We present results from two projects, conducted in Ireland and Sweden respectively. In both countries, data were collected through questionnaires, as well as through student interviews in Sweden. We draw on the notion of concept image and describe the components of students’ evoked concept images. The students’ responses involved e.g. ”reflection”, ”reverse”, and concrete ”examples”, while just a few students gave explanations relating to the definition of inverse functions. We found that the conceptions of inverses as reflections and reverse processes are important and relatively independent of local factors, and the data seemed to suggest that a ”reverse” conception is linked to an appreciation of injectivity more than a ”reflection” conception.

    Oral presentations as a tool for promoting metacognitive regulation in real analysis

    Margrethe Naalsund and Joakim Skogholt

    Abstract
    Real Analysis is for many students their first proof-based mathematics course, and many find it challenging. This paper studies how oral presentations of mathematical problems for peers can contribute to students’ metacognitive reflections. The paper discusses several aspects tied to preparing for, and carrying out, oral presentations, that seem to spur important sub-components of metacognitive regulation such as planning, monitoring, and evaluating. Thoughtful guidance from an expert encouraged the students to further monitor their cognition, and evaluate their arguments and cognitive processes when expressing their reasoning to their peers.

    Mathematics lecturers’ views on the teaching of mathematical modelling

    Stephanie Treffert-Thomas, Olov Viirman, Paul Hernandez-Martinez and Yuriy Rogovchenko

    Abstract
    The paper reports on the views and use of mathematical modelling (MM) in university mathematics courses in Norway from the perspective of lecturers. Our analysis includes a characterisation of MM views based on the modelling perspectives developed by Kaiser and Sriraman (2006). Through an online survey we aimed to identify the main perspectives held in higher education by mathematics lecturers and the underlying rationale for integrating (or not) MM in university courses. The results indicated that most respondents displayed a realistic perspective on MM when it came to their professional practice. There was a more varied response when it came to their views on MM in teaching. Regarding conditions influencing the use or non-use of MM in teaching, these mainly concerned the mathematical content and the institutional practices.

    Peer assessment of mathematical understanding using comparative judgement

    Ian Jones and David Sirl

    Abstract
    It is relatively straightforward to assess procedural knowledge and difficult to assess conceptual understanding in mathematics. One reason is that conceptual understanding is better assessed using open-ended test questions that invite an unpredictable variety of responses that are difficult to mark. Recently a technique, called comparative judgement, has been developed that enables the reliable and valid scoring of open-ended tests. We applied this technique to the peer assessment of calculus on a first-year mathematics module. We explored the reliability and criterion validity of the outcomes using psychometric methods and a survey of participants. We report evidence that the assessment activity was reliable and valid, and discuss the strengths and limitations, as well as the practical implications, of our findings.

    Characterising undergraduate mathematics teaching across settings and countries: an analytical framework

    Angeliki Mali and Georgia Petropoulou

    Abstract

    This paper explores the characteristics of teaching of a sample of university mathe-matics teachers in two countries, Greece and Great Britain, and in two settings, lectures and tutorials, seeking to identify a common ground for undergraduate mathe-matics teaching. Our observations of teaching and our sociocultural perspectives enabled us to develop a framework for a detailed description of the observed teaching. The description reveals categories of teaching actions, and the associated tools teachers use in selecting tasks for their students, providing comprehensive explanations, extending students’ mathematical thinking, or evaluating students’ mathematical meaning. The findings are across settings and countries in the direction of a profound understanding of undergraduate mathematics teaching.

    Developing practice through research into university mathematics education

    Simon Goodchild and Barbara Jaworski

    Abstract
    The paper provides a very brief outline review of research into some key issues that affect students’ performance in mathematics in higher education. Community of practice theory is used to frame and focus the discussion. Policies regarding the recruitment of students, institutional practices for grouping students and the cultures of teaching and learning mathematics are considered. The research reviewed provides a context for examining the contributions of the research reports included within this thematic issue of NOMAD. The reports address three themes: regular approaches adopted in teaching mathematics in higher education, innovative approaches to teaching and learning, with emphasis on student participation in the educational process, and the characteristics of mathematical knowledge students appropriate. The paper endorses calls for large scale studies, especially those which relate teaching approaches, both regular and innovative, to the qualities and characteristics of students’ learning. The absence of a single overarching theoretical framework that embraces all the studies is also perceived as an obstacle that interferes with scientific developments in the field of researching university mathematics education. However, the value of teachers researching their own practice and their students’ learning is argued to be crucial for developing knowledge ”in practice” and this underscores the value of the papers included in this issue of NOMAD, both for the authors and the inspiration of other higher education mathematics teachers who, it is hoped, will be inspired to engage in similar studies.

    Analysing genomgång: a Swedish mathematics teaching lesson event

    Paul Andrews and Niclas Larson

    Abstract
    In this paper, drawing on group interviews focused on Swedish upper secondary students’ perspectives on school mathematics, we analyse participants’ use of the noun genomgång. Loosely translated as a ”whole class event during which the teacher goes through something” and for which there is no English equivalent, the word was used by both interviewers and interviewees even when referring to di erent forms of whole class activity. Analyses identi ed four broad categories of genomgång based on their form and function. With respect to form, genomgångs were either transmissive or participative. With respect to function they were either instructional or problem solving.

    The development of pre-service teachers’ self-efficacy in teaching mathematics

    Annette Hessen Bjerke

    Abstract
    Teacher efficacy has received much attention in the general field of educational research, but applications in mathematics teacher education are few. In order to deepen the understanding of the nature and development of self-efficacy in teaching mathematics (SETM) during teacher education, the study presented here followed over a period of two years pre-service teachers (PSTs) preparing to teach primary school mathematics in Norway (grades 1–7, ages 6–13). Their developing SETM was investigated by means of an instrument designed to target the core activity of teaching mathematics: helping a generic child with mathematics tasks. A comparison of responses collected from 191 novice PSTs with those from the same cohort two years later (n = 103) shows a rise in SETM in the typical PST, and indicates the nature of the development of SETM during teacher education.

    Research as praxis, en route theory/practice teacher-researcher collaboration: a self-study

    Sharada Gade

    Abstract
    This paper relates to project related instructional interventions, conducted via teacher-researcher collaboration in a Grade Four mathematics classroom. Drawing upon cultural historical activity theory or CHAT perspectives, such conduct exemplies research as praxis. While CHAT perspectives argue for a theory/practice approach, enabling practitioners to act on their re exivity and address contradictions found in ongoing practice; research as praxis views practitioner re exivity as central to pursuing openly ideological work and practising in empirical inquiry what one preaches in theoretical formulations. Such pursuit led to our becoming stakeholders in each other’s professional practice and the conduct of interventions becoming the shared object of both teaching and research. In teacher-researcher collaboration realising expansive learning activity, it was possible to question modernist assumptions which view abstract theory as applicable to any concrete practice and take political action in dialectic with theory.

    A review of the impact of formative assessment on student achievement in mathematics

    Torulf Palm, Catarina Andersson, Erika Boström and Charlotta Vingsle

    Abstract
    Research reviews show that formative assessment has great potential for raising student achievement in general, but there is a need for reviews of formative assessment in individual subjects. This review examines its impact on student achievement in mathematics through an assessment of scientific journal articles published between 2005 and 2014 and indexed in Web of science. Through the use of search terms such as ”formative assessment”, ”assessment for learning” and ”self-regulated learning”, different approaches to formative assessment were included in the review. While varying in approach, they all share the defining characteristic of formative assessment: agents in the classroom collect evidence of student learning and, based on this information, adjust their teaching and/or learning. The results show positive relations between student achievement in mathematics and the ways of doing formative assessment included in the review.

    Theorizing the interactive nature of teaching mathematics: contributing to develop contributions as a metaphor for teaching

    Andreas Eckert

    Abstract
    The teachers’ role in teacher-student interaction in mathematics has received increased attention in recent years. One metaphor used to describe teaching in teacher-student interaction is to describe teaching as a learning process itself, in terms of learning to develop learning. The aim of the present study is to contribute to the conceptualization and understanding of this view of teaching mathematics. This is done by introducing and elaborating on a new conceptual framework, describing teaching as Contributing to Develop Contributions (CDC). The CDC framework is constructed by combining the theory of symbolic interactionism with a complementing metaphor for learning; learning as contribution. The CDC-framework is illustrated in the context of experimentation-based, interactive teaching of probability. The analysis shows how the CDC-framework helps in coming to understand how teachers develop their own contributions to manipulate the negotiation of meaning of mathematics in the classroom and thereby also develops the students’ contributions. In the presented case we can see how CDC particularly helps in giving account of how a teacher develops her way of using symbols and indications and adjust her own interpretations during a whole class discussion where the teacher and students interpret the empirical results of a random generator. In addition, the analysis also illustrates how the framework draws our attention to how a teacher can contribute to the negation of meaning, and so, to students’ opportunities to learn, by making her own interpretations and ways of ascribing meaning to objects transparent to the students in the interaction.

    A tool for understanding pupils’ mathematical thinking

    Hanna Viitala

    Abstract
    This article provides a tool for studying pupils’ mathematical thinking. Mathematical thinking is seen as a cognitive function that is highly influenced by affect and meta-level of mind. The situational problem solving behaviour is studied together with metacognition and affect which together with pupils’ view of mathematics form a dynamic construct that reveals pupils’ mathematical thinking. The case of Daniel is introduced to illustrate the dynamic nature of the framework.

    First and second language students’ achievement in mathematical content areas

    Jöran Petersson

    Abstract
    This study compares Swedish first (n = 2 253) and second language (n = 248) students’ achievement in mathematical content areas specified by the TIMSS-framework. Data on mathematics achievement from three national tests 2007–2009 in school year 9 are used. The present study found that the achievement difference between the mathematical content areas algebra and number was smaller for second language students than for first language students and this result holds with statistical significance (p = 0.016). The same holds for algebra versus data and chance (p = 0.00053). A hypothesis for further research is suggested; that students immigrating in late school years have contributed to the observed result by bringing experiences from other curricula into their new schooling.

    Studier av undervisningskunnskap i matematikk: internasjonale trender og nordiske bidrag

    Reidar Mosvold

    Sammandrag
    De siste tiårene har forskere vist stadig mer interesse for den matematiske kunnskapen som er spesifikt knyttet til matematikkundervisningen. I denne artikkelen diskuteres nordiske bidrag til forskningen på dette feltet i lys av internasjonale trender. Diskusjonene bygger på resultater fra en litteraturstudie av 190 empiriske artikler som ble publisert i perioden 2006–2013. I tillegg trekkes her inn nordiske artikler etter 2013. Noen av disse studiene fokuserte på kunnskapens innhold og natur, andre fokuserte på hvordan denne kunnskapen kan utvikles, mens en tredje gruppe studier undersøkte hvordan lærerkunnskapen påvirker elevenes resultater og kvaliteten på undervisningen. Videre nordisk forskning på feltet kan blant annet bidra til styrking av teori og praksistilknytning.

In this article, Nordic contributions to this field are discussed in light of international research trends. The discussions draw upon results from a literature review of 190 empirical articles that were published in 2006–2013. In addition, Nordic studies that have been published after this are included in the discussion. Some of the studies focus on the nature and composition of this knowledge, other studies focus on the development of this knowledge, whereas a third group of studies focus on how teachers’ knowledge contributes to student learning and the quality of instruction. Further Nordic research in this field might contribute to strengthening theoretical perspectives and connections to practice.

    Dependence between creative and non-creative mathematical reasoning in national physics tests

    Helena Johansson

    Abstract
    It is known from previous studies that a focus on rote learning and procedural mathematical reasoning hamper students’ learning of mathematics. Since mathematics is an integral part of physics, it is assumed that mathematical reasoning also influences students’ success in physics. This paper aims to study how students’ ability to reason mathematically affects their success on different kinds of physics tasks. A descriptive statistical approach is adopted, which compares the ratio between conditional and unconditional probability to solve physics tasks requiring different kinds of mathematical reasoning. Tasks from eight Swedish national physics tests for upper secondary school, serve as a basis for the analysis. The result shows that if students succeed on tasks requiring creative mathematical reasoning, the probability to solve the other tasks on the same test increases. This increase is higher than if the students succeed on tasks not requiring creative mathematical reasoning. This result suggests that if students can reason mathematically creatively, they have the ability to use their knowledge in other novel situations and thus become more successful on tests.

    Et miljø for algebraisk generalisering og dets innvirkning på studenters matematiske aktivitet

    Heidi Strømskag

    Sammandrag
    Denne artikkelen handler om hvordan egenskaper ved en didaktisk situasjon i matematikk påvirker studenters muligheter til å løse en algebraisk generaliseringsoppgave. Studien er gjennomført innenfor et lærerutdanningsprogram ved en høgskole, og datamaterialet består av matematikkoppgaven og et videoopptak av tre studenters samarbeid for å løse oppgaven. Transkripsjonen av videoopptaket er analysert ved den konstant komparative metoden, der teorien for didaktiske situasjoner i matematikk (TDS) er brukt for å forstå hvilke egenskaper ved den didaktiske situasjonen som begrenser studentenes muligheter for å løse oppgaven. Den observerte didaktiske situasjonen er en ordinær undervisningssituasjon i den forstand at den ikke er et resultat av didaktisk ingeniørvirksomhet basert på TDS. Resultatene fra analysen viser hvordan to faktorer skaper avstand mellom lærerens hensikt med den gitte matematikkoppgaven og studentenes aktivitet knyttet til oppgaven. Den ene faktoren handler om begrepet ”matematisk setning” som studentene tillegger en annen betydning enn den læreren legger til grunn; den andre faktoren handler om lærerens bruk av et generisk eksempel uten at de generelle egenskapene til eksemplet blir diskutert. Studien bidrar til innsikt i sammenhengen mellom et miljø for en adidaktisk situasjon og den matematikkunnskapen som studenter har mulighet for å utvikle i det aktuelle miljøet.

    Abstract
    This article is about how features of a didactical situation in mathematics at a university college a ect students’ opportunity to solve an algebraic generalisation task. The study is conducted within a teacher education programme for primary and lower secondary education. The empirical material contains the mathematical task and a video recorded episode of three students’ collaborative engagement with the task. The transcription of the episode is analysed by the constant comparative method, where the theory of didactical situations in mathematics (TDS) is used to conceptualise what features of the didactical situation that constrain the students’ opportunity to solve the task. The observed didactical situation is a regular teaching situation in the sense that it is not a result of didactic engineering based on TDS. Analysis of the data shows how two factors create a gap between the teacher’s intention with the mathematical task and the students’ engagement with the task. The first factor is about the concept of ”mathematical sentence” of which the students have a different conception than intended by the teacher. The second factor is about the teacher’s use of a generic example without a discussion of its general properties. The study provides insight into the relationship between a milieu for an adidactical situation and the mathematical knowledge that the milieu enables the students to develop.

    Formative assessment in Swedish mathematics classroom practice

    Catarina Andersson, Erika Boström and Torulf Palm

    Abstract
    Research shows that substantial learning gains are possible through the use of formation assessment. However, little is known about Swedish mathematics teachers’ use of formative assessment, and thus about the possible value of professional development programmes. This study uses teacher interviews and classroom observations to examine the classroom practice of 38 randomly selected primary and secondary school teachers in a mid-sized Swedish municipality. A framework of formative assessment comprising one big idea and five Key strategies structured the analysis. The study identifies characteristics of current formative assessment practices. The results show that the teachers do use a variety of formative assessment activities, but also that there is much room for development towards a more effective formative classroom practice.

    Matematikundervisning för begåvade elever – en forskningsöversikt

    Attila Szabo

    Sammanfattning
    Artikeln redovisar de huvudsakliga pedagogiska och organisatoriska metoder relaterade till begåvade elevers matematikundervisning som fokuseras i forskningslitteraturen – även könsskillnader, motivation och matematiskt begåvade elevers sociala situation i klassrummet diskuteras. Översikten visar att det finns åtgärder – t ex frivillig acceleration i ämnet där undervisningen är anpassad till elevens förkunskaper och kapacitet eller arbete med utmanande uppgifter i prestationshomogena grupper – som antas ha goda effekter på begåvade elevers kunskapsutveckling i matematik. Analysen visar också att det kan uppfattas som problematiskt att vara begåvad i matematik samt att begåvade flickor upplever vissa aspekter av matematikundervisningen annorlunda jämfört med motsvarande grupp pojkar.

    Abstract
    The present article offers an overview of those main methodological and pedagogical approaches associated with gifted pupils’ education in mathematics which are focused in the research literature. Furthermore, the article discusses gender differences, motivation and some central aspects of mathematically gifted pupils’ social situation in the classroom. The analysis shows that there are some pedagogical and organizational approaches, e.g. voluntary acceleration where the teaching is adapted to the knowledge and the capacity of the participants or working with challenging mathematical problems in performance-homogenous groups, which may have good effects on gifted pupils’ mathematical achievement. The overview also indicates that mathematically gifted adolescents are facing difficulties in their social interaction and that gifted female and male pupils are experiencing certain aspects of their mathematics education differently.

    The older the better? Are younger Norwegian adults losing ground on basic numeracy skills?

    Mary G. Billington and Egil Gabrielsen

    Abstract
    Results from the OECD survey of adult skills, 2012 brought good tidings for Norway. The average numeracy score for the Norwegian adult population lies well over the OECD average. However, a closer look at the age skill profile shows that while older Norwegians score well over the OECD average for their age group, younger Norwegians score around the OECD average. Comparing these results to results from an earlier study of adult skills, conducted in 2003, suggests a downward trend in numeracy proficiency for the younger generation. We discuss recent school reforms as a possible cohort effect influencing this trend.

    The teaching of mathematical problem-solving in Swedish classrooms: a case study of one grade five teacher’s practice

    Anna Pansell and Paul Andrews

    Abstract
    In this paper we examine the teaching of mathematical problem-solving to grade five students of one well-regarded and experienced Swedish teacher, whom we call Mary. Working within a decentralised curriculum in which problem-solving is centrally placed, Mary is offered little systemic support in her professional decision making with respect to problem-solving instruction. Drawing on Lester’s and Schroeder’s descriptions of teaching for, about and through problem-solving, we draw on multiple sources of data, derived from interviews and videotaped lessons, to examine how Mary’s problem-solving-related teaching is constituted in relation to the weakly framed curriculum and the unregulated textbooks that on which she draws. The analyses indicate that Mary’s emphases are on teaching for and about problem-solving rather than through, although the ambiguities that can be identified throughout her practice with respect to goals, curricular aims and the means of their achievement can also be identified in the curricular documents from which she draws.

    Convergences and influences of discourses in an online professional development course for mathematics teachers

    Eva-Lena Erixon

    Abstract
    Despite the ever-increasing number of online professional development (OPD) courses, few studies have examined online education for mathematics teachers. This article reports on a case study of discourses in an OPD course for mathematics teachers concerning the convergence and influence of discourses in course seminar discussions and in mathematics teaching in school when course participants are given the task of translating their insights into actual teaching, with a focus on the participants’ discussions of their own and one another’s video-recorded lessons. The analysis shows that there is a convergence of discourses in the seminars and in the school context related to a focus on concepts and everyday life connections. However, the study also suggests that there is a risk of students remaining outside in an ”everyday discourse”, in which knowledge of mathematics might be useful, but mathematics is discussed in imprecise and simplified terms.

    Measuring temperature within the didaktic space of preschool

    Ola Helenius, Maria L. Johansson, Troels Lange, Tamsin Meaney and Anna Wernberg

    Abstract

    The informal character of preschool mathematics, engaged in during children’s play, places complex requirements on preschool teachers. It also leads to challenges in developing appropriate analytical tools for researching teacher work. In this paper a framework, the ”didaktic space”, is described and used to analyse interactions between preschool teachers and children in relationship to mathematical learning situations. An interaction between a preschool teacher and a group of children about how to compare their temperatures is analysed, using this framework. The analysis focuses on how the teacher’s contributions as well as those of the children changed as the role of the mathematics changed. The paper discusses how the didaktic space offers a nuanced understanding of preschool mathematical situations, both to researchers and to teachers.

    What characterises mathematical conversations in a Norwegian kindergarten?

    Trude Fosse

    Abstract

    This paper presents a study of young children’s mathematical conversations in a Norwegian kindergarten and provides examples to illustrate some of their characteristics. Using points made in previous research about conversations and mathematics, an analysis of an interaction involving a group of children who are putting a toy together exemplifies what can and what cannot be considered a mathematical conversation. For a conversation to be considered mathematical, it is suggested that it must include not only references to mathematics, but also specific structural elements in the conversation, as well as valuing participants’ contributions and encouraging participants to reflect on the mathematical theme, thereby promoting learning.

    Trude Fosse

    Trude Fosse is assistant professor at the University of Bergen. Her research interests concern beginners education in mathematics, with a particular interest in mathematical conversations and how mathematics is handled in kindergartens and primary schools. Another interest concerns how the mathematics in teacher education programs can support students’ learning and teaching practices.
