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

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

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.Magnus Fahlström

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 openended 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 openended tests. We applied this technique to the peer assessment of calculus on a firstyear 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 mathematics teachers in two countries, Greece and Great Britain, and in two settings, lectures and tutorials, seeking to identify a common ground for undergraduate mathematics 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.

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 entrylevel 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 learnercentred 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 firstyear 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 proofbased 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 subcomponents 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 TreffertThomas, Olov Viirman, Paul HernandezMartinez 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 nonuse of MM in teaching, these mainly concerned the mathematical content and the institutional practices.

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 preservice teachers’ selfefficacy 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 selfefficacy in teaching mathematics (SETM) during teacher education, the study presented here followed over a period of two years preservice 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 teacherresearcher collaboration: a selfstudy
Sharada Gade
Abstract
This paper relates to project related instructional interventions, conducted via teacherresearcher 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 teacherresearcher 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 ”selfregulated 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 teacherstudent interaction in mathematics has received increased attention in recent years. One metaphor used to describe teaching in teacherstudent 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 CDCframework is illustrated in the context of experimentationbased, interactive teaching of probability. The analysis shows how the CDCframework 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 metalevel 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 TIMSSframework. 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.
Abstract
In recent decades, researchers have shown an increasing interest in the mathematical knowledge that is specific to the work of teaching mathematics. 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.

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.

Dependence between creative and noncreative 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.
