    Students’ strategies of expanding fractions to a common denominator – a semiotic perspective

    Andreas Lorange and Reinert A. Rinvold

    Abstract

    The aim of this article is to identify students’ strategies while solving tasks which involve the expansion of fractions to a common denominator. In this case study we follow two groups of 11 year old students and their use of the artifact multilink cubes in the solution process. The analysis of the students’ strategies is based upon a semiotic-cultural framework. Five different types of strategies are reported: trial-and-error, factual, contextual, embodied-symbolic and symbolic. The concept of semiotic contraction is also used in the analysis.

    ”Just-in-time teaching” in undergraduate mathematics

    Kristina Juter and Jan-Fredrik Olsen

    Abstract

    We compared five groups of students to investigate the effects of ”Just-in-time teaching” (JiTT), a method designed to both help students keep up with the often fast pace of undergraduate calculus and to deepen their learning. In total, 137 students participated in the study. The outcome is discussed in terms of conceptual and procedural knowledge in relation to examination and other assessment tasks. We observed an improvement on the assessed items and a shift in study habits.

    Gender differences favouring females in Estonian university students’ views of mathematics

    Indrek Kaldo and Markku S. Hannula

    Abstract

    This study reports on first-year Estonian university students’ views of mathematics. The data were collected from 970 university students of different disciplines. The participants completed a Likert-type questionnaire that was compiled from previously published instruments. The results reveal the importance of Mastery Goal Orientation as central to the structure of their views of mathematics. In this study, in five of six dimensions, females hold a more positive view of mathematics than do male students. Performance-Approach Goal Orientation was the only dimension in which we found no statistically significant gender difference. In all the other dimensions, the female respondents expressed a more positive affect towards mathematics: They showed a more powerful mastery orientation, valued mathematics more, felt more competent, perceived their teacher more positively, and cheated less frequently.

    A comparison of three frameworks for measuring knowledge for teaching mathematics

    Hege Kaarstein

    Abstract

    This paper presents a comparison of three different frameworks used in research projects aimed at measuring knowledge for teaching mathematics. As the included cases all build on Shulman’s theoretical framework for teacher knowledge, in which the categories subject matter content knowledge (CK) and pedagogical content knowledge (PCK) are central, his framework was used as a reference. To enable comparison across the frameworks, each framework’s categories were analysed and organized taxonomically. The results indicate agreement on a superordinate level. However, important differences were found in the operationalisation of the basic level cat- egories mathematics CK and mathematics PCK. As the basic level normally represents clear communication of categories, this paper suggests that more attention to the operationalisation of basic level categories is needed.

    Muligheter og begrensninger for studenters læring i praksisopplæring – eksempel fra en førveiledningsdialog i matematikk

    Raymond Bjuland, Arne Jakobsen og Elaine Munthe

    Sammanfattning

    Denne artikkelen presenterer resultater fra en førveiledningsdialog mellom en grunnskolelærerstudent og hennes praksislærer fra en ordinær fjerde semesters praksisopplæringsperiode. Ved hjelp av en dialogisk tilnærming forsøker analysen å identifisere dialogsekvenser som inneholder ytringer som er støttende eller begrensende med tanke på å hjelpe studenten til å rette oppmerksomheten mot elevers læring av likeverdige brøker på 7. trinn. Inspirert av perspektiver som fremmer et positivt læringsmiljø i klasserommet (Bransford, Brown & Cocking, 2000) blir ytringer innenfor en dialogsekvens kategoriserte som elevsentrerte, kunnskapssentrerte og vurderingssentrerte med tanke på å planlegge en undervisningsøkt. Dette danner et grunnlag for å diskutere styrker og svakheter ved førveiledningsdialogen.

    Abstract

    This article presents results from analyses of a mentoring session between a student teacher and her mentor teacher which took place prior to instruction during a fourth semester field practice placement. Using a dialogic approach, the analyses identify utterances that are perceived as supportive or constraining in relation to enabling the student to direct attention towards pupils’ learning about fractions in grade 7. Bransford mfl.’s (2000) approaches to learning have inspired the development of analytical categories to assess the degree of learner centered, knowledge centered and assessment centered utterances, and thus to discuss strengths and weaknesses in the mentoring session.

    Prolifing Swedish teachers’ knowledge base in probability

    Per Nilsson and Torsten Lindström

    Abstract

    This paper aims at profiling Swedish teachers’ knowledge base in probability. 43 teachers in compulsory school answered a questionnaire on probability estimation tasks and concept tasks. In the concept tasks, they were challenged to explain their solutions and the content involved in the probability estimation tasks. We distin- guish five patterns in the teachers’ knowledge profile: 1) a basic understanding of the theoretical interpretation of probability, 2) problems with structuring compound events, 3) difficulty with conjunction and conditional probability, 4) a higher degree of common content knowledge than of specialized content knowledge and 5) limited understanding of random variation and principles of experimental probability.

    The first foci of elementary school students dealing with prognosis tasks in interviews

    Judith Stanja

    Abstract

    The nature of stochastics is not only characterized by its relationship as a model of the real phenomena described by it as well as by its usage to find hypotheses to be tested in reality, but also by its peculiar characteristic of modeling the relation between model and real phenomena. Stochastic prognoses can be one key concept for ele- mentary school stochastics to implement the fundamental idea of the specific nature of stochastics. Stochastic prognoses may be characterized as reflexive statements containing the structural components focus, evaluation and justification. Examples are given to illustrate these components. The paper outlines some a priori determined conceptional requirements for stochastic prognoses to give a first orientation of what can be expected from primary school children. It is assumed that the topics, ques- tions and problems stochastics is concerned with, are part of a culture that a child is just entering. To learn more about the ways in which primary school students under- stand and express stochastic prognoses, a series of half-structured interviews with 3rd graders (age 8-9) were videotaped and transcribed before and after a series of lessons. This contribution concentrates on the foci that children might adopt when dealing with prognosis tasks in interviews for the first time. An overview of the reconstructed types of foci is given and illustrated by examples. The stochastic foci reconstructed so far may be classified as simple foci that could be further described as sequential or aggregate foci. A case study of one child in a pre-interview shows what and how foci might be articulated when being confronted with the new semiotic means of a list.

    Judith Stanja

    Judith Stanja studied mathematics and history of science at the Georg- August University of Göttingen (Germany) and at Lund University (Sweden) with an emphasis on stochastics. Currently, she is working on her Phd in mathematics education at the University of Duisburg-Essen (Germany). Her research interests include early stochastic learning, con- straints for the development of stochastic knowledge, and representations.

    A modelling approach to probability – analysing students’ conceptual structures

    Theodosia Prodromou

    Abstract

    This research study investigates how middle school students use probability to model random behaviour in real-world contexts and how they articulated fundamental prob- abilistic concepts to show aspects of the mental models that they generated. This article is concerned with the conceptual structures that the students develop when exploring computer-based simulations. The results suggest that the students relied on their experience to provide a context reality from which to construct their mental model of the situation, from which they then defined the probability model. While the students attempted to build mental models, they checked the adequacy of the mapping between their probability models and reality by interrogating the context of their personal experiences. The results also suggest that the way students express this relationship between signal and noise seems to have a particular importance in building comprehensive models that link observed data to modelling distributions.

    Barns bruk av digitale verktøy i barnehagen: muligheter for å gjøre seg matematiske erfaringer

    Martin Carlsen

    Sammanfattning

    Denne artikkelen har som mål å studere hvordan barnehagebarn gjør seg matematiske erfaringer gjennom å bruke digitale verktøy. Ved å ta et sosiokulturelt perspektiv på læring og utvikling studeres den sosiale interaksjonen mellom barn og voksne når disse diskuterer og samhandler med ulike digitale verktøy. Analysene av transkriberte dialoger i to grupper, hver bestående av en voksen og to barn, gir innblikk i det matematiske læringspotensialet som oppstår når barna interagerer med de digitale verktøyene. Dette læringspotensialet knytter seg til de matematiske begrepene telling og tallsymbol, deriblant matematiskteoretiske komponenter som sortering, subitizing, parkobling og kardinalprinsipp. Samtidig viser analysen at interaksjonen med de digitale verktøyene har potensiale til å gi ytterligere næring til approprieringsprosessen av de implisitte matematiske begrepene som finnes i applikasjonene.

    Abstract

    This study aims at illuminating aspects of how kindergarten children make mathematical experience through the use of digital tools. By taking a sociocultural perspective on learning and development the social inter- action amongst children and adults is studied when these discuss and collaborate in using different digital tools. The analyses of transcribed dialogues in two groups comprising one adult and two children show the learning potential that unfolds when the children interact with the digital tools. This learning potential is relative to the mathematical con- cepts of counting and number digits, including mathematical theoretical components of sorting, subitizing, one-to-one correspondence and cardinality. Furthermore, the analyses show that interaction with the digital tools carries potentials regarding how to further nurture the appropriation process with respect to the implicit mathematical concepts inherent in the applications.

    Arithmetic textbooks in Estonia, Iceland and Norway – similarities and differences during the nineteenth century

    Kristín Bjarnadottír, Andreas Christiansen and Madis Lepik

    Abstract

    This paper identifies similarities and eventual differences in the development of public mathematics education in the nineteenth century in three Northern-European countries: Estonia, Iceland and Norway. Special attention is paid to how these developments were reflected in the first arithmetic textbooks written in the vernacular in these countries. By the end of the century, all three countries had taken serious steps to develop public education, and arithmetic textbooks, meant for self-instruction or for use in elementary schools, had been published. The content and style of presentation of these textbooks in Estonia, Iceland and Norway are described and compared in the paper, revealing their roots in Northern-European culture: Lutheran Protestantism, Enlightenment and pedagogical currents initiated by Comenius, Pestalozzi and Spencer, emphasizing meaningful learning. Their educational aims were important driving forces in growing national movements in the respective countries by contributing to capability to manage own resources and use of own vernacular, resulting in increased self-esteem.

    An analysis of mathematical modelling in Swedish textbooks in upper secondary school

    Peter Frejd

    Abstract

    A new national curriculum has recently been implemented in the Swedish upper secondary school where one of the goals to be taught is modelling ability. This paper presents a content analysis of 14 ”new” mathematical textbooks with the aim to investigate how the notion of mathematical modelling is presented. An analytic scheme is developed to identify mathematical modelling in the textbooks and to analyse modelling tasks and instructions. Results of the analysis show that there exist a variety of both explicit and implicit descriptions, which imply for teachers to be attentive to complement the textbooks with other material.

    Preparing future teachers for interdisciplinarity: designing and implementing a course for pre-service upper secondary teachers

    Uffe Thomas Jankvist, Jan Alexis Nielsen and Claus Michelsen

    Abstract

    Educational researchers and policy-makers have for some time touted the need for interdisciplinary teaching. But while there are many educational, democratic, and economic arguments for bringing an increased attention to interdisciplinary teaching, there has been a striking lack of exposure of the question of how future teachers, who are largely educated in a mono-disciplinary fashion, can best become equipped to introduce genuinely interdisciplinary teaching activities to their future students. This article presents some preliminary reflections upon a graduate course at the University of Southern Denmark, which aims to prepare future science and mathematics teachers for interdisciplinary teaching, and which has been designed on the basis of influential theoretical expositions of the concept of interdisciplinarity.

    Uffe Thomas Jankvist is associate professor of mathematics education at Aarhus University, Department of Education, Campus Emdrup, Denmark. In addition to the topic of interdisciplinarity, his research interests include the use of history of mathematics, applications of mathematics, and philosophy of mathematics in mathematics education, both from a theoretical and an empirical point of view, including also students’ beliefs about and images of mathematics as a (scientific) discipline. Besides being an editor of Nomad, he is currently involved in a new initiative at Roskilde University to design and implement an educational program for in-service upper secondary school mathematics teachers to become ”math counselors”.

    Teacher-assisted open problem solving

    Markus Hähkiöniemi, Henry Leppäaho and John Francisco

    Abstract

    Previous research has developed several problem-solving models and suggested that the teacher plays a crucial role in guiding students’ problem solving. However, less is known about the particularities of problem solving and teacher guidance when dealing with open problems which include multiple possible solution pathways. The aim of this study is to understand students’ open problem-solving processes and teachers’ ways of supporting them. Data collection involved videotaping one 9th grade mathematics lesson with two video cameras and capturing the screens of the students’ computers. Seven student pairs worked on an open problem using GeoGe- bra under the guidance of a teacher trainee. We found that students had various kinds of problem-solving processes and that the teacher had a crucial role in guiding them. We elaborate on 9 ways how the teacher guided students to change between phases in open problem solving.

    Att ändra arbetssätt och kultur inom den inledande aritmetikundervisningen

    Dagmar Neuman

    Sammanfattning

    Utgående från den holistiska kunskapssyn som representerar fenomenologin och den fenomenografiska forskningsansatsen diskuterar jag i den här artikeln observationer redovisade i min nu drygt tjugosex år gamla avhandling, i boken Räknefärdighetens rötter samt i en senare studie av hur barn dividerar. Observationerna gäller dels elever som deltar i specialundervisning i matematik i grundskolan, samt elever i gymnasieskolan som anser sig lida av matematiksvårigheter, och dels skolnybörjare som ännu inte har undervisats i matematik. De visar

    – att det som främst tycks förorsaka grava eller specifika matematiksvårigheter är att eleverna saknar talföreställningar samt förståelse för sambandet mellan de fyra räknesätten

    – att sådana begrepp och föreställningar knappast utvecklas genom skolans tabellträning

    – att många barn intuitivt börjar utveckla talföreställningar före skolstarten, samtidigt med att de formar konkreta representationer som blir till abstrakta föreställningar om tal.

    Avslutningsvis ställer jag frågan: skulle den stora andel elever som nu lämnar grundskolan utan godkänt betyg i matematik möjligen kunna reduceras genom ett paradigmskifte inom den kultur som styr hur den grundläggande aritmetiken behandlas under de första skolåren?

    Abstract

    Setting out from the holistic view of knowledge representing pheno- menology and the phenomenographic research approach, I have in this article revisited the observations presented in my now twenty-six year old dissertation The origin of arithmetic skills, the Swedish book Räknefärdighetens rötter and a later study of how children divide. One side of the observations concerns elementary and middle school pupils who take part in special education as well as high school pupils who believe they suffer from severe math difficulties; the other concerns seven year old first year pupils without any formal education in the field of mathematics. These observations show

    – that the primary cause of severe or specific math difficulties seems to be the absence of numerical representations and of the concep- tual understanding of the inverse relation between addition and subtraction

    – that those concepts and representations are probably not developed through the table-training usually used at school; but

    – that many children intuitively begin to use those concepts or arith- metic laws before they enter school, whilst simultaneously crea- ting numerical representations, which in due time become tools for thinking in numerical terms.

    Finally, the question is posed: would a shift of paradigm within the culture now ruling the ways in which arithmetic is introduced to first year pupils possibly reduce the great number of pupils who now fail mathematics when leaving school at the end of grade nine?

    Affective pathways and interactive visualization in the context of technological and professional mathematical knowledge

    Inés Mª Gómez-Chacón

    Abstract

    This article reports the findings for a qualitative study on the use of dynamic geometry systems (DGS) and their impact on students’ affective pathways. The approach adopted is to view affect through the lens of a representational system. The participants, mathematics teacher trainees, were asked to solve geometric locus exercises using GeoGebra software. The results reveal a number of features that characterize subjects’ local and global affect. Future teachers’ local affect when using imagery in computerized environments was found to be impacted by the balance between their analytical-algebraic and graphic reasoning and their understanding of the tools at their avail and their use in the instrumental deconstruction of geometric figures. Evidence was observed that linked student teachers’ global affect, in turn, to their motivation as defined by their goals and self-concept.

    Emotional atmosphere in third-graders’ mathematics classroom – an analysis of pupils’ drawings

    Anu Laine, Liisa Näveri, Maija Ahtee, Markku S. Hannula and Erkki Pehkonen

    Abstract

    The aim of this study is to find out what kind of emotional atmosphere dominates in third-graders’ mathematics lessons. The analysis is based on pupils’ drawings. In total 133 drawings were analyzed by looking for content categories related to a holistic evaluation of emotional atmosphere during mathematics lesson. As a summary we can conclude that the emotional atmospheres in the mathematics lessons are mainly positive even though the differences between the classes are large. Furthermore, it can be said that asking pupils to do drawings is a good and many-sided method to collect data about the emotional atmosphere of a class.

    Stability of beliefs in mathematics education: a critical analysis

    Peter Liljedahl, Susan Oesterle and Christian Bernèche

    Abstract

    The field of mathematics education has assumed for too long that stability is an inherent and definable characteristic of beliefs. In this article we explore the validity of this claim through the critical analysis of 92 journal articles, conference papers, and book chapters. Using a stringent definition of what it means for a belief to be stable, we conclude that the body of research on mathematical beliefs is inconsistent in its use of this construct. The aggregated results of our analysis also indicate that stability and instability are not mutually exclusive characteristics of beliefs.

    Abstract

    In the 1980s the meaning of beliefs for teaching and learning aroused also to the con- sciousness of mathematics educators. Therefore, here it is firstly sketched the research field of mathematical beliefs, in order to understand why belief research has been a topic for an international research group for more than 30 years. The aim of the paper is to have a look at the history of MAVI and to describe its development within the years 1995–2012. A special look is given at the birth of the MAVI group in the middle of the 1990s and then its development through the last 18 years will be described. Also some statistics on the MAVI meetings and their participants are presented. And in the appendix the total list of the MAVI proceedings is documented.

    Interplay of cognition and affect in undergraduate math students’ careers: insights from recursive partitioning

    Chiara Andrà and Guido Magnano

    Abstract

    Data collected in entrance tests for undergraduate curricula in mathematics at the University of Turin are analysed using the recursive partition method, to obtain classification trees for different ”response variables” describing academic achievement or drop-out. The input factors include both math abilities and several affective and motivational factors, the latter having being assessed using internationally validated questionnaires. We argue that classification trees can provide unexpected insight into the interplay of such factors for academic success or failure, specifically for math students.

    Primary teachers’ affect: a crucial variable in the teaching of mathematics

    Cristina Coppola, Pietro Di Martino, Tiziana Pacelli and Cristina Sabena

    Abstract

    Mathematics education is strongly interested in defining ”what is necessary for teaching mathematics effectively”. The main directions of research emphasize the cognitive side of the answer to this question, trying to describe what kind of knowledge is needed in order to teach mathematics effectively. Starting from the point that teachers’ affect plays a crucial role in determining the quality of teaching, we discuss this issue from a theoretical point of view, introducing the construct of ”attitude towards mathematics teaching”. Within this theoretical framework we conducted a study with 189 primary school pre-service teachers, investigating teachers’ emotions, beliefs and attitudes. In this paper, we analyze and discuss the relationship among the participants’ emotional disposition towards mathematics and towards the idea of having to teach it, their past experiences as math-students and the current perceived competence in mathematics.

    Dialogue between past and future mathematical identities

    Sonja Lutovac and Raimo Kaasila

    Abstract

    Pre-service teachers’ school-time experiences have been addressed much in mathematics

    education research. These experiences have been shown to have a central meaning for pre-service teachers’ views of mathematics and their present mathematical identities. However, the identity is not only bound to the past and present, but it also extends to the future. Further, pre-service teachers’ anticipations of the future have been overlooked in the research on identity in a mathematics education context. We focus here on the mathematical identity work of two pre-service teachers and its dialogue between the past and the future. We compare the cases of one Finnish and one Slovenian pre-service teacher, who reported having had negative experiences with mathematics during their school years. Based on the results, two different types of mathematical identity work were identified; resulting from the different facilitators used in mathematics education courses.

    (In)consistent? The mathematics teaching of a novice primary school teacher

    Hanna Palmér

    Abstract

    This article focuses on the mathematics teaching of Helena, a Swedish novice teacher. Helena is one of seven teachers in a case study of primary school mathematics teachers’ professional identity development. She is also an example of a teacher whose mathematics teaching, from an observer’s perspective, may appear inconsistent with her talk about mathematics teaching. However, in this article a conceptual framework aimed at analysing professional identity development will be used making the process of her mathematics teaching visible and then her mathematics teaching appear as consistent.

    Prospective mathematics teachers’ metaphors for mathematics, teaching, and the teacher’s role

    Päivi Portaankorva-Koivisto

    Abstract

    This study sheds light on Finnish preservice mathematics teachers’ (n = 16) views of mathematics, teaching, and the teacher’s role. Data was gathered via metaphors at three time points during teacher students’ pedagogical studies, in academic year 2011–2012. The analysis was conducted inductively, but based on categories found in previous studies. The results indicated that prospective mathematics teachers’ metaphors for mathematics mostly involved picturing the self-existent quality of mathematics. Their metaphors for teaching referred to the ups and downs in teaching, and their metaphors for the teacher’s role were involved with the characteristics of the teacher’s personality. One possible explanation for these results centres round mathematics student teachers’ life situations. They have studied mathematics as their major at the department of mathematics for 2–3 years just before they started their pedagogical studies, and they have just experienced their very first and overwhelming lessons as teachers.

    Comparing mathematics teachers’ beliefs about good teaching: the cases of Estonia, Latvia and Finland

    Madis Lepik, Anita Pipere and Markku S. Hannula

    Abstract

    The article presents results from a cross-cultural NorBa project Mathematics teachers’ educational beliefs. We report on Estonian, Latvian and Finnish lower secondary mathematics teachers’ espoused beliefs about good teaching. A principal component analyses identified a two-component structure of teachers’ beliefs about good teaching: (1) Reasoning and conceptual understanding and (2) Mastery of skills and facts. Cross-cultural differences were identified in both of these dimensions. Latvian teachers indicated the strongest agreement with reasoning and conceptual understanding, Estonian teachers with mastery of skills and facts, while Finnish teachers scored lowest on both dimensions. Moreover, we analysed the amount of teachers with different profiles with regard to these two dimensions. The results suggest both common conceptual core of teachers’ beliefs on mathematics teaching and certain cultural influence on the profile of these beliefs.

    Feeling of innovation in expert problem posing

    Igor’ Kontorovich and Boris Koichu

    Abstract

    This paper is one of the reports on a multiple-case study concerned with the intertwining between affect and cognition in the mechanisms governing experts when posing new mathematical problems. Based on inductive analysis of a single case of an expert poser for mathematics competitions, we suggest that the desire to experience the feeling of innovation may be one of such mechanisms. In the case of interest, the feeling was realized through expert’s reflections on the problems he created in the past, by systematically emphasizing how a new problem was innovative in comparison with other familiar problems based on the same nesting idea. The findings are discussed in light of past research on expert problem posers and expert problem solvers.

    Making sense of a ”misleading” graph

    Oduor Olande

    Abstract

    Given the importance of a critical-analytical disposition in the case of graphical artefacts, this paper explores graphicacy based on students’ answers to an item from PISA survey test. Primarily, results from the written test were analyzed using PISA’s doubledigit rubrics or coding. In evaluating these categories, it is observed that just a small percentage of students are able to produce answers that reflect a critical-analytical approach with respect to the use of statistical/mathematical operators and forms of expressions. Secondly, video observation shows that students tend to employ what is perceived as an ”identification approach” while discussing the task. Whereas elements of mathematical and statistical ideas can be identified in the students’ discussion, these are not explicitly stated and are largely submerged in everyday concerns and forms of expression.

    Student teachers’ work on instructional explanations in multiplication – representations and conversions between them

    Anita Valenta and Ole Enge

    Abstract

    In this study we are analysing student teachers’ instructional explanations. The study is based on student teachers’ written work on two different tasks about different strategies and properties in multiplication and explaining these. Our research questions concern the type of representation registers student teachers use in their explanations. In explanations where several representation registers are used, we analyse what can be challenges in conversions between representations. Data is analysed using the framework of Duval’s cognitive analysis, and analyses and discussions are related to development of mathematical knowledge for teaching.

    I need advanced mathematics to pursue the career of my choice”. Norwegian students’ motivations for enrolling in mathematics and plans for post-secondary studies

    Ida Friestad Pedersen

    Abstract

    Participation in advanced science and mathematics courses in upper secondary school is a gateway to tertiary education and career opportunities in the STEM fields (Science, Technology, Engineering, and Mathematics). The purpose of this study is to investigate Norwegian final-year upper secondary school students’ motivations for choosing to enroll in the most advanced mathematics course offered (3MX), as well as to ascertain their plans for post-secondary education. Since females are underrepresented in mathematics and mathematics-related fields of study, special attention is paid to the gender perspective. The analyses are based on questionnaire data from the large-scale international achievement study TIMSS Advanced, and are framed by the expectancy-value model developed by Eccles and her colleagues (1985). Results show that the subject’s utility value was the primary reason for students’ enrollment in mathematics; that interest in mathematics as a school subject is somewhat more important to the girls than to the boys; and that there are some gender differences in students’ plans for post-secondary studies in the STEM fields.

    Ida Friestad Pedersen

    Ida Friestad Pedersen is a PhD-student in the doctoral program at the University of Oslo, and works as a lecturer at the University of Tromsø.

    Innovative approaches to teaching mathematics in higher education: a review and critique

    Mahmoud Abdulwahed, Barbara Jaworski and Adam R. Crawford

    Abstract

    This paper provides a snapshot of emerging trends in mathematics teaching in higher education for STEM subjects (Science, Technology, Engineering and Mathematics). Overwhelmingly, papers identify a focus on conceptual understandings of mathematics in comparison to understanding that is instrumental or procedural. Calls for reform of mathematics teaching have been the basis for a range of studies; responses to these calls have embraced innovative methods for implementing changes in learning and teaching of mathematics, sometimes rooted in constructivist ideology. Observed trends have been categorised in six groups. In many studies, technology is being used as an enabler of reforms. Constraints to implementing new approaches in mathematics teaching are indicated. Discussion of contemporary research questions that could be asked as a result of the shift towards teaching mathematics in innovative ways is provided and is followed by a critique of the underlying theoretical positions, essentially that of constructivism.

    Upper secondary school students’ gendered conceptions about affect in mathematics

    Lovisa Sumpter

    Abstract

    This study explores upper secondary school students’ conceptions about gender and affect in mathematics. Two groups of students from Swedish Natural Science Programme each answered a questionnaire; the first with a focus on boys and girls in general and the other with a focus on individuals themselves. The results from two questionnaires were compared. The first questionnaire revealed a view of rather traditional femininities and masculinities, a result that did not repeat itself in the second questionnaire. There was a discrepancy between traits students ascribed as gender different and traits students ascribed to themselves.

    Structure of university students’ view of mathematics in Estonia

    Indrek Kaldo and Markku S. Hannula

    Abstract

    This study reports on first-year Estonian university students’ view of mathematics. The data was collected from 970 university students of different disciplines. The participants filled out a Likert-type questionnaire that was developed using previously published instruments. The study confirmed that several different attitudes, beliefs, and motivational orientations can be identified and validly measured as separate components of Estonian university students’ view of mathematics. However, the low reliability of some scales highlights the necessity for careful testing of instruments in any new population.

    Methodological issues when studying the relationship between reading and solving mathematical tasks

    Magnus Österholm and Ewa Bergqvist

    Abstract

    In this paper we examine four statistical methods used for characterizing mathematical test items regarding their demands of reading ability. These methods rely on data of students’ performance on test items regarding mathematics and reading and include the use of regression analysis, principal component analysis, and different uses of correlation coefficients. Our investigation of these methods focuses on aspects of validity and reliability, using data from PISA 2003 and 2006. The results show that the method using principal component analysis has the best properties when taking into account aspects of both validity and reliability.

    Using strands of tasks to promote growth of students’ mathematical understanding

    John Francisco and Gunnar Gjone

    Abstract

    This article reports on the mathematical activity of a group of five high school students (15–16 year olds) who worked together on a series of challenging task in combinatorics and probability. The students were participants in an after-school, classroom-based, longitudinal research on students’ development of mathematical ideas and different forms of reasoning in several mathematical content strands. The purpose of the article is to contribute insights into how to promote growth of students’ mathematical understanding through problem-solving activities. In particular, the article shows that problem-solving activities involving strands of challenging tasks have the potential to promote growth of students’ mathematical understanding by providing opportunities for students to engage in reasoning by isomorphism. This is a type of reasoning whereby students rely on structural similarities, i.e., isomorphism among mathematical tasks to solve or deepen their understanding of the tasks. Implications for classroom teaching, and environmental conditions that promote reasoning by isomorphism are also discussed.

    Interference of subtraction strategies

    Per-Olof Bentley

    Abstract

    This study concerns a particular kind of mistake that a number of pupils made when subtracting two positive whole numbers. The aim was to analyse the cause behind this particular mistake. According to the pupils, the difference was equal to the subtrahend. It was found that the pupils counted down to the subtrahend. But instead of finding the answer as the number of steps between the two terms, the pupils applied the last-number-word rule and gave the subtrahend, which was the last mentioned number word, as the result. When seeing subtraction as a concept, it could be assumed that the lack of experience of subtraction as a comparison and as equalization played a decisive role for this mistake. A comparable mistake described in previous research is also analysed.

    Comparing perceptions of mathematics: Norwegian and Finnish university students‘ definitions of mathematics

    Miika Vähämaa and Kennet Härmälä

    Abstract

    The article presents a comparison between Norwegian and Finnish university students’ perceptions of what mathematics is. To carry out the comparison, a mix of qualitative – the creation of abstract and concrete categories for mathematics representations – and quantitative (regression modeling) methods was used in the study. The main result of the study is that Norwegian students were more homogenous in their responses and the vast majority perceived mathematics in concrete terms. The Finnish students, on the contrary, showed greater variety in their responses. There are not many comparative studies among Nordic countries regarding students’ perceptions of mathematics. Therefore this study contributes to improving our knowledge about the possible differences and similarities on students’ perceptions of mathematics among Nordic students. A total of 239 students were asked how they perceive mathematics, numbers and personal applicability of mathematics via an open questionnaire. We propose that the divergent perceptions of mathematics stem from different types of communication cultures that surround mathematics. The argument is made that perceptions of mathematics should be treated as a type of mathematical knowledge that is valuable whenever mathematics is communicated.

    Abstract

    In order to design appropriate professional development programs for teachers, an instrument has been developed in the U.S. to measure teachers’ mathematical knowledge for teaching. The process of translating and adapting these measures for use in other countries involves several challenges. This article focuses on issues related to the multiple-choice format of the items. Analyses of focus-group interviews reveal that the multiple-choice format may complicate the items. The teachers’ reflections about the format in this Norwegian case contribute to the understanding of this important challenge.

    What characterises the heuristic approaches in mathematics textbooks used in lower secondary schools in Norway?

    Tom Rune Kongelf

    Abstract

    In this paper I present findings of an analysis of how mathematics textbooks treat heuristic approaches. The aim of this analysis is to give a characterisation of the occurrence of nine well-known heuristic approaches by analysing 740 examples presented in six ninth grade textbook series. The findings show that many of the problems in the examples are being solved by using one or more heuristic approaches, but the characteristics of the examples and the textbooks’ lack of discussion of the approaches themselves make it challenging to teach and learn these in school. The heuristic approaches seem to be used rather incidentally, which is supported by the fact that none of the textbooks explicitly treat or mention problem solving.
