Det kommer med tiden : Från lärarstudent till matematiklärare
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The main purpose of this thesis is to investigate how future pre- and primary school mathematics teachers change their approaches to mathematics and mathematics education during their subject studies, and also how this view has affected their teaching of mathematics after graduation. A qualitative interview method was used in combination with observations, notes, sound recordings, video recorded mathematics classes and materials produced by the teacher in order to answer the research questions. The research was carried out in two parts. The institutional theory has been used as theoretical framework throughout. This perspective was supplemented by a design theoretical perspective in part two. In the first investigation it became clear that the language used by the students is under change, and that they use terms from the national curriculum as well as the aims of the programme syllabus when they discuss mathematics teaching. The results from the observations later show that four out of five of the teachers have a clear connection to the sort of teaching they said they want to conduct, in that there is a clear relationship between the sort of teaching that they claim to perform and the sort of teaching they actually perform. From the overall results, it is apparent that teachers one year after graduation describe that they feel well prepared for teaching mathematics in preschool and primary school. This is interesting in the light of their dissatisfaction with the limited emphasis on concrete recommendations and "tips" directly after their graduation. In fact, the teachers said that in practice it turned out that their education provided a more stable and secure foundation than they described it to be shortly after having completed their mathematics studies. They say that during their education they developed knowledge and skills that enabled them to be better prepared for their future work roles than they believed themselves likely to become.

Prövningen av en skola för alla : nationella provet i matematik i det tredje skolåret
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis presents the contribution to research that my doctoral education led to. My starting point was a large scale qualitative research project (here after called the VR-project) which reviewed the implementation of national tests in the third grade on the subject of mathematics. The VR-project investigated how the test affected the pupils with a special focus on pupils in need of special support. An urge to look further into issues concerning the support, the pupil in need and the test was revealed in he initial VR-project. These issues therefore constitutes the problem area of this thesis. The VR-project studied a total of 22 classrooms in two different municipalities' during 2010- 2012. The methodology used for this project was inspired by ethnography and discourse analysis. The raw data consisted of test instructions, video observations of the actual test subjects, interviews from teachers and pupils about the test, the support that was given throughout the testing as well as the observations and interviews of the pupils requiring special assistance. Activated discourses and positions of the participants were demarcated. The results revealed that a traditional testing discourse, a caring discourse and a competitive discourse are activated during the tests. The testing discourse is stable and traditional. Much of what was shown and said in classrooms, routines and rules regarding the test were repeated in all the schools and in all the classrooms. The discourse on support is affected by ambiguity, which is revealed especially when issues of pupils’ equity is put against the tests equality. This is connected to the teachers restricted agency to give support due to the teacher position as a test taker. The positions in need that are available to students are not the same in pupils, teachers and steering documents. The situation is especially troublesome for pupils that do not manage Swedish good enough to take the test and for pupils in need of special support. Some of the conclusions from this thesis is that the national test format: Disciplines not only the pupil, but also the teacher, the classroom and the school at large. Results indicate that the test:Activates a focus on achievementLeads attention away from learning Activates issues of accountability Influences pupils and teachers with stakes involvedBesides evaluating knowledge, the test disciplines not only the pupil, but also the teacher, the classroom and the school at large. Discussing the national test as an arena for equity might be a way towards attaining equality in education for all pupils.

Mathematics and mathematics education - two sides of the same coin : creative reasoning in university exams in mathematics
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Avhandlingen består av två ganska olika delar som ändå har en del gemensamt. Del A är baserad på två artiklar i matematik och del B är baserad på två matematikdidaktiska artiklar. De matematiska artiklarna utgår från ett begrepp som heter polynomkonvexitet. Grundidén är att man skulle kunna se vissa ytor som en sorts ”tak” (tänk på taket till en carport). Alla punkter, eller positioner, ”under taket” (ungefär som de platser som skyddas från regn av carporttaket) ligger i något som kallas ”polynomkonvexa höljet.” Tidigare forskning har visat att för ett givet tak och en given punkt så finns det ett sätt att avgöra om punkten ligger ”under taket”. Det finns nämligen i så fall alltid en sorts matematisk funktion med vissa egenskaper. Finns det ingen sådan funktion så ligger inte punkten under taket och tvärt om; ligger punkten utanför taket så finns det heller ingen sådan funktion. Jag visar i min första artikel att det kan finnas flera olika sådana funktioner till en punkt som ligger under taket. I den andra artikeln visar jag några exempel på hur man kan konstruera sådana funktioner när man vet hur taket ser ut och var under taket punkten ligger. De matematikdidaktiska artiklarna i avhandlingen handlar om vad som krävs av studenterna när de gör universitetstentor i matematik. Vissa uppgifter kan gå att lösa genom att studenterna lär sig någonting utantill ur läroboken och sen skriver ner det på tentan. Andra går kanske att lösa med hjälp en algoritm, ett ”recept,” som studenterna har övat på att använda. Båda dessa sätt att resonera kallas imitativt resonemang. Om uppgiften kräver att studenterna ”tänker själva” och skapar en (för dem) ny lösning, så kallas det kreativt resonemang. Forskning visar att elever i stor utsträckning väljer att jobba med imitativt resonemang, även när uppgifterna inte går att lösa på det sättet. Mycket pekar också på att de svårigheter med att lära sig matematik som elever ofta har är nära kopplat till detta arbetssätt. Det är därför viktigt att undersöka i vilken utsträckning de möter olika typer av resonemang i undervisningen. Den första artikeln består av en genomgång av tentauppgifter där det noggrant avgörs vilken typ av resonemang som de kräver av studenterna. Resultatet visar att studenterna kunde bli godkända på nästan alla tentorna med hjälp av imitativt resonemang. Den andra artikeln baserades på intervjuer med sex av de lärare som konstruerat tentorna. Syftet var att ta reda på varför tentorna såg ut som de gjorde och varför det räckte med imitativt resonemang för att klara dem. Det visade sig att lärarna kopplade uppgifternas svårighetsgrad till resonemangstypen. De ansåg att om uppgiften krävde kreativt resonemang så var den svår och att de uppgifter som gick att lösa med imitativt resonemang var lättare. Lärarna menade att under rådande omständigheter, t.ex. studenternas försämrade förkunskaper, så är det inte rimligt att kräva mer kreativt resonemang vid tentamenstillfället.

To explore and verify in mathematics
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation consists of four articles and a summary. The main focus of the studies is students' explorations in upper secondary school mathematics. In the first study the central research question was to find out if the students could learn something difficult by using the graphing calculator. The students were working with questions connected to factorisation of quadratic polynomials, and the factor theorem. The results indicate that the students got a better understanding for the factor theorem, and for the connection between graphical and algebraical representations. The second study focused on a the last part of an investigation, the verification of an idea or a conjecture. Students were given three conjectures and asked to decide if they were true or false, and also to explain why the conjectures were true or false. In this study I found that the students wanted to use rather abstract mathematics in order to verify the conjectures. Since the results from the second study disagreed with other research in similar situations, I wanted to see what Swedish teachers had to say of the students' ways to verify the conjectures. The third study is an interview study where some teachers were asked what expectations they had on students who were supposed to verify the three conjectures from the second study. The teachers were also confronted with examples from my second study, and asked to comment on how the students performed. The results indicate that teachers tend to underestimate students' mathematical reasoning. A central focus to all my three studies is explorations in mathematics. My fourth study, a revised version of a pilot study performed 1998, concerns exactly that: how students in upper secondary school explore a mathematical concept. The results indicate that the students are able to perform explorations in mathematics, and that the graphing calculator has a potential as a pedagogical aid, it can be a support for the students' mathematical reasoning.

Assessing mathematical creativity : comparing national and teacher-made tests, explaining differences and examining impact
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Students’ use of superficial reasoning seems to be a main reason for learning difficulties in mathematics. It is therefore important to investigate the reasons for this use and the components that may affect students’ mathematical reasoning development. Assessments have been claimed to be a component that significantly may influence students’ learning. The purpose of the study in Paper 1 was to investigate the kind of mathematical reasoning that is required to successfully solve tasks in the written tests students encounter in their learning environment. This study showed that a majority of the tasks in teacher-made assessment could be solved successfully by using only imitative reasoning. The national tests however required creative mathematically founded reasoning to a much higher extent. The question about what kind of reasoning the students really use, regardless of what theoretically has been claimed to be required on these tests, still remains. This question is investigated in Paper 2. Here is also the relation between the theoretically established reasoning requirements, i.e. the kind of reasoning the students have to use in order to successfully solve included tasks, and the reasoning actually used by students studied. The results showed that the students to large extent did apply the same reasoning as were required, which means that the framework and analysis procedure can be valuable tools when developing tests. It also strengthens many of the results throughout this thesis. A consequence of this concordance is that as in the case with national tests with high demands regarding reasoning also resulted in a higher use of such reasoning, i.e. creative mathematically founded reasoning. Paper 2 can thus be seen to have validated the used framework and the analysis procedure for establishing these requirements. Paper 3 investigates the reasons for why the teacher-made tests emphasises low-quality reasoning found in paper I. In short the study showed that the high degree of tasks solvable by imitative reasoning in teacher-made tests seems explainable by amalgamating the following factors: (i) Limited awareness of differences in reasoning requirements, (ii) low expectations of students abilities and (iii) the desire to get students passing the tests, which was believed easier when excluding creative reasoning from the tests. Information about these reasons is decisive for the possibilities of changing this emphasis. Results from this study can also be used heuristically to explain some of the results found in paper 4, concerning those teachers that did not seem to be influenced by the national tests. There are many suggestions in the literature that high-stake tests affect practice in the classroom. Therefore, the national tests may influence teachers in their development of classroom tests. Findings from paper I suggests that this proposed impact seem to have had a limited effect, at least regarding the kind of reasoning required to solve included tasks. What about other competencies described in the policy documents? Paper 4 investigates if the Swedish national tests have had such an impact on teacher-made classroom assessment. Results showed that impact in terms of similar distribution of tested competences is very limited. The study however showed the existence of impact from the national tests on teachers test development and how this impact may operate.

Difficult to read or difficult to solve? : The role of natural language and other semiotic resources in mathematics tasks
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- When students solve mathematics tasks, the tasks are commonly given as written text, usually consisting of natural language, mathematical notation and different types of images. This is one reason why reading and interpreting such texts are important parts of being mathematically proficient, at least within the school context. The ability utilized when dealing with aspects of mathematical text is denoted in this thesis as a mathematical reading ability; this ability is useful when reading mathematical language, for example, in task text. There is, however, a lack of knowledge of what characterizes this mathematical language, what students need to learn regarding the mathematical language, and exactly which mathematical language that tests should preferably assess. Therefore, the purpose of this thesis is to contribute to the knowledge of aspects of difficulty related to textual features in mathematics tasks. In particular, one aim is to distinguish between a difficulty that has to do with a mathematical ability and another that has not. Different types of text analyses are utilized to capture textural features that might be demanding for the students when reading and solving mathematics tasks. Aspects regarding vocabulary are investigated both in a literature review and in a study where corpora are used to analyse word commonness. Other textual analyses focus on textual features that concern mathematical notation and images, besides natural language. Statistical methods are used to analyse potential relations between the textual features of interest and both task difficulty and task demand on reading ability. The results from the research review are sparse regarding difficult vocabulary, since few of the reviewed studies analyses word aspects separately. Several of the analysed textual features are related to aspects of difficulty. The results show that tasks with more words that are uncommon both in a mathematical context and in an everyday context, may favour students with good reading ability rather than students with good mathematical ability. Another textual feature that is likely to be demanding for students, is if the task texts contains many meaning relations, for example, when several words refer to the same or similar object. These results have implications for the school practice both regarding textual features that are important from an educational perspective and regarding the construction of tests. The research does also contribute to an understanding of what characterizes a mathematical language.

Med uppgift att lära : om matematikuppgifter som en resurs för lärande
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Elevers möjligheter att utveckla sin kunskap i matematik påverkas av de uppgifter de arbetar med. Det är möjligt att göra en distinktion mellan rutinuppgifter och matematiska problem. En rutinuppgift är en uppgift som en elev kan lösa genom att använda en välbekant metod, eller genom att imitera en förlaga. För att lösa ett matematiskt problem behöver däremot eleven konstruera en för henne ny lösningsmetod. För att utveckla sin matematiska kunskap behöver elever möta såväl rutinuppgifter som matematiska problem. Problemlösning kan skapa förutsättningar för en elev att utveckla såväl en kreativ problemlösningsförmåga, som en konceptuell, matematisk förståelse.Avhandlingen består av fem studier med ett fokus på matematikuppgifter, där studie 1-3 syftade till att undersöka vilka möjligheter att arbeta med matematisk problemlösning som elever i gymnasieskolan erbjuds. Detta undersöktes genom läroboksanalyser, studier av elevers arbete med uppgifter och av elevers uppfattningar om matematik. Uppgifter i läroböcker från 12 länder analyserades (studie 1) och ungefär 10 procent av dessa var matematiska problem. Eleverna arbetade (studie 2) nästan uteslutande med de uppgifter som av läroboksförfattarna kategoriserats som enkla och utan att arbeta problemlösande. Bland dessa uppgifter var andelen matematiska problem 4 procent. Inte heller bland uppgifter som kategoriserats som till exempel ’problemlösning’ eller ’utforska’ var matematiska problem i övervikt. Resultaten var relativt lika för de tolv ländernas läroböcker. Elevers uppfattningar om att rutinarbete är säkrare och något som är rimligt att förvänta sig i matematik (studie 3) kan ha en ytterligare påverkan på deras möjligheter att arbeta problemlösande. Med tanke på de positiva effekter som påvisats för elever som arbetar med problemlösning verkar elevers möjligheter att arbeta med problemlösning begränsade. Det finns potential i att såväl utveckla innehållet i läroböckerna för att öka andelen matematiska problem, som i ett medvetet uppgiftsurval från dessa läroböcker.Syftet med studie 4 och 5 var att fördjupa förståelsen för problemlösning. Ett analytiskt ramverk har utvecklats för att identifiera kreativa, konceptuella och andra utmaningar i elevers problemlösning. Respektive utmaning karaktäriserades för att ytterligare fördjupa förståelsen för dessa och för problemlösning. Elevers arbete med matematiska problem (studie 4) och lärares förväntningar på de utmaningar elever möter vid problemlösning (studie 5) studerades. Konceptuella och kreativa utmaningar visade sig vara de mest centrala vid elevers problemlösning. Genom den karaktäristik som knöts till respektive utmaning kan svårigheter med att identifiera, framför allt kreativa utmaningar, och relationen mellan uppgift och utmaning diskuteras.

Elevers möjligheter att ta ansvar för sitt lärande i matematik : En skolstudie i postmodern tid
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation examines the ‘individual perspective’ of the Swedish school system’s policy documents by studying compulsory schooling’s stated aim of developing students’ ability and opportunities to assume responsibility for, be actively involved in and influence their own learning. Its main objective is to investigate the opportunities of compulsory school students to assume responsibility for their learning with regard to mathematics. In order to understand these opportunities, I have initially investigated how the school system in general and instruction in mathematics, in particular, are organised and carried out. I have also examined what forms student responsibility for, influence on and participation in their learning take in the context of instruction in mathematics. This study also intends to highlight questions related to understanding the social circumstances that affect students’ opportunities for assuming responsibility for their learning. The empirical material used for this study was collected via interviews and observations. The study was conducted as a case study using students from early schoolyear classes to the ninth school year at a Swedish compulsory school, with the purpose of analysing education in mathematics throughout the course of the compulsory schoolyear one to nine education. In considering the question of how responsibility, influence and participation is presented in the Swedish school system, it was also important to study the way students, teachers and school heads express and implement the idea of students assuming responsibility for their education both in general and more specifically with regard to their learning in mathematics. An important theoretical starting point for the study has been the phenomenological lifeworld concept. The concept has contributed to the study’s design and has provided the tools with which to examine student circumstances in an individual perspective. The adoption of a design theory perspective has also been important, especially in carrying out and analysing classroom-based observations. The most common methods and forms of work used in the classroom involved individual work using a mathematics textbook. The textbook itself proved to greatly determine the course and nature of instruction in mathematics, with the teacher’s role being one of assisting and supporting the students to progress through the book. The study also reveals obvious changes taking place in schools at present – from having previously focused on group-based, collective activities, the trend is moving increasingly toward more individual forms of work, e.g. that which is labelled ‘individual study’. The challenges faced by mathematics education in compulsory schools relate to the school’s position vis-à-vis the individual in relation to the group; how the exchange of experience between teachers can be made possible both within and across year levels in compulsory schools; and how mathematics education can reduce its dependence on textbooks and perhaps thereby strengthen the didactic roles and duties of teachers.

Lärande i matematik : Om resonemang och matematikuppgifters egenskaper
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Since mathematical tasks are central to the teaching of mathematics, it is crucial to extend our knowledge of the characteristic features of tasks that are conducive to student development of problem-solving and reasoning abilities as well as conceptual understanding. The aim of the dissertation is to investigate how different types of mathematical tasks affect student learning and choice of learning strategies. This is done through a twofold approach: 1) to test the hypothesis that tasks affording students the opportunity and responsibility for constructing knowledge are more effective learning tools than tasks for which the solution is presented, and 2) to analyse the educational message embedded in the teacher’s formulation of the mathematical tasks on the Internet. The main conclusion is that the type of task students engage with is important for their learning of new things. The participants who were engaged in creating their own solutions were less successful during practice but performed better on the tests in comparison with the participants who were involved in solving the tasks with a given method. The results of the sub-studies indicate that in a learning situation consisting of repeated practice of a solution method, the results are closely related to the students’ cognitive ability. The investigation shows that tasks inviting the opportunity to be solved through creative reasoning, to a certain extent serve a compensatory function in relation to students’ cognitive resources. This means that the participants need not put in so much effort in the test situation if they have practiced creative reasoning. One conclusion to be drawn from the study of the educational message in Internet documents, when it comes to teachers’ formulation of tasks, is that there are many teachers who design tasks that encourage young students’ creative reasoning. However, the educational message in the documents shows that the teachers demand relatively little of the students in the majority of the tasks. The result indicates that there is some uncertainty about how to formulate and use tasks to support the older student’s mathematical development. The way the tasks are formulated indicates a lack of discursive tools to clarify the intended educational situation. Thus, the qualities in the tasks are hidden resources.

On Mathematical Reasoning : being told or finding out
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- School-mathematics has been shown to mainly comprise rote-learning of procedures where the considerations of intrinsic mathematical properties are scarce. At the same time theories and syllabi emphasize competencies like problem solving and reasoning. This thesis will therefore concern how task design can influence the reasoning that students apply when solving tasks, and how the reasoning during practice is associated to students’ results, cognitive capacity, and brain activity. In studies 1-3, we examine the efficiency of different types of reasoning (i.e., algorithmic reasoning (AR) or creative mathematically founded reasoning (CMR)) in between-groups designs. We use mathematics grade, gender, and cognitive capacity as matching variables to get similar groups. We let the groups practice 14 different solution methods with tasks designed to promote either AR or CMR, and after one week the students are tested on the practiced solution methods. In study 3 the students did the test in and fMRI-scanner to study if the differing practice would yield any lasting differences in brain activation. Study 4 had a different approach and focused details in students’ reasoning when working on teacher constructed tasks in an ordinary classroom environment. Here we utilized audio-recordings of students’ solving tasks, together with interviews with teachers and students to unravel the reasoning sequences that students embark on. The turning points where the students switch subtask and the reasoning between these points were characterized and visualized. The behavioral results suggest that CMR is more efficient than AR, and also less dependent on cognitive capacity during the test. The latter is confirmed by fMRI, which showed that AR had higher activation than CMR in areas connected to memory retrieval and working memory. The behavioral result also suggested that CMR is more beneficial for cognitively less proficient students than for the high achievers. Also, task design is essential for both students’ choice of reasoning and task progression. The findings suggest that: 1) since CMR is more efficient than AR, students need to encounter more CMR, both during task solving and in teacher presentation, 2) cognitive capacity is important but depending on task design, cognitive strain will be more or less high during test situations, 3) although AR-tasks does not prohibit the use of CMR they make it less likely to occur. Since CMR-tasks can emphasize important mathematical properties, are more efficient than AR- tasks, and more beneficial for less cognitively proficient students, promoting CMR can be essential if we want students to become mathematically literate.
