Talet om talen : Vuxenmatematikens retoriska vändning
This is an empirical study of how the mathematical talk of adult learners constructs/reconstructs different mathematical discourses. The study is to be regarded as an attempt to develop a discursive approach within the field of mathematics education and to complicate the status of mathematics in education and in society in general. My theoretical underpinnings consist of three possible mathematical discourses ? coercive, regulative and emancipative mathematics. From a discursive psychology perspective, I let these discourses function as analytical interpretive repertoires in relation to the adult learners? rhetorical use of mathematics and their claiming of mathematical subject-positions, named the coerced, the self-regulating and the responsible mathematician.
Elevers problemlösningsstrategier : En studie av gymnasieelevers val av strategier vid problemlösning
The purpose of this study is to examine senior high school students? strategies and reasoning when solving mathematical problems and make a review of the concept problem solving. The purpose is also to examine if the students? choice of strategies are influenced when their mathematical knowledge is improved.The study was conducted in two science classes at a senior high school. All the students were asked to individually solve two mathematical problems.
Simulerat kreativt resonemang i matematikföreläsningar
Empirical research shows that a possible reason why Swedish students mathematical knowledge deteriorates can be a too big focus on imitative reasoning, i.e. recalling solutions or follow algorithms, and a lack of creative mathematical reasoning, i.e. when a student construct his/her own solution and motivates its plausibility with mathematically well-founded arguments. The purpose of this study is therefore to examine if, and in what way, lecturers can provide students an opportunity to learn creative reasoning by simulating creativity in their presentations of examples. Six lectures were observed and 22 task situations were analyzed with respect to three aspects; reflection, plausibility and mathematical foundation, which are to be present in the situation if the reasoning will be seen as simulated creative.
Speciallärares kommunikation med matematiksvaga elever
Undersökningen beskriver den matematiska kommunikationen mellan speciallärare och matematiksvaga elever. Den empiriska datan består av två matematiklektioner från år 9 i grundskolan. Datan analyserades för att finna olika typer av kommunikation.Lärarna var i många delar medvetna i sitt sätt att kommunicera med eleverna och undervisningsmiljön kändes trygg. Under lektionerna observerades två parallella språk, ett vardagsanknutet och ett matematiskt språk. Det framkom att ett tydligt förhållningssätt beträffande matematiskt språk kan underlätta för elevens inlärning samt medvetandegöra läraren om den kommunikativa betydelsen i undervisningen med styrdokumentens mål i fokus. .
Självkänsla och motivation : En studie kring gymnasieelevers självkänsla och motivation inom ämnet matematik

The study had focus on role that the teachers play in these aspects. The study was done by using both a qualitative and quantitative approach. The qualitative method was interviews based on six interviews with two teachers and four students from two different classes. The quantitative method was a questionnaire study that was done in both classes.
Betong - Förvånansvärt lättflytande!
Concrete is a very common construction material. It´s characteristics are strength, durability and formablility. Superplasticizer is a common admixture, which changes the properties of concrete.
Today (spring 2007) there are no certian mathematical methods to calculate the required percentage of this admixture needed to give the necessary set slump flow in the overall concrete recipe.
Concrete batching companies must therefor experiment with different amount of superplasticizer in order to meet the specified slump and strength.
The purpose og this report is to investigate if any mathematical relation can be established between the amount of superplasticizer used and the slump flow achieved.
After carrying out some practical experiments using four different superplasticizers a direct relationship can be establish between the percentage of admixture used and the slump/flowability achieved. Unfortunatly at present due to the numerous variables, the calculation of mathematical formula can not be achieved..
Matematik i förskola : En studie av lek i undervisning
The purpose of my study is to examine how four preschool teachers go about using the term play in children's early mathematical development. In order to fulfill the purpose of this study, I have the following questions:How the preschool teachers visualize mathematics in children?s play?What reflections have the preschool teachers about the importance of play for children's mathematical learning in preschool?How do the preschool teachers see on their own role in the children's play?In this study, I have conducted a semi-structured qualitative interviews based on the interviews with four preschool teachers from various departments in a preschool. I have also conducted some observations to complete my study. Whereas in my analysis of the researched material, I have used Vygotsky's theory.The survey shows that the preschool teachers are aware of the use of mathematical language and concepts in children?s different activities which were conducted daily in the preschool.
Matematikverkstad : hur kan lärare och elever arbeta där?
The starting point of this work has been to get knowledge about teachers working in a mathematical workshop with the students. I also wanted to investigate what students think about math, both within the workshop and in traditional teaching.To achieve this I chose to interview a teacher in charge within the framework of a mathematical workshop, and six students in the 5th grade. I also did a lesson observation with the purpose to see how well the teacher?s tutoring agrees with the results of the interview.In this study I have discovered that the lessons in the mathematical workshop are planned after what the students are working with in the textbook. The teacher opens the lessons with the whole class and then splits it up in groups.
Undervisning för elever med särskilda matematiska förmågor : En studie om hur lärares undervisning i grundskolans tidigare år bedrivs och anpassas till elever med särskilda matematiska förmågor.
The purpose of this study is to see how some teachers in primary school creates and adapts their mathematics teaching for students with special mathematical abilities. It also aims to identify opportunities and challenges that teachers see in creating a teaching adapted to these students.In this study, qualitative interviews has been done to collect data. The interviews were conducted with five teachers who all are active in the primary school.The study results show that there is great variation in how the interviewed teachers create their mathematics teaching for students with special mathematical abilities. The use of mathematics book proved to be significant for how this adaptation took place. The result also shows that the teachers? explanations for the choice of the adaptations that they make in teaching vary.
Att lösa sudoku med SAT-lösare
Yahtzee is a popular dice game around the world. The complexity makes the game interesting to play and analyze. This report compares the effectiveness of the mathematically optimal strategy with a strategy that can be used for casual play. The rules used are those of the Nordic variant Yatzy, in which a few but important rules are different from the American Yahtzee. To evaluate the everyday strategy 100,000 games was simulated in a java program written specifically for this purpose.

Textinnehållets betydelse för läsförståelsen : En komparativ studie av flickor och pojkar i åk 7
Research reports as PISA and PIRLS show that reading comprehension among Swedish students have deteriorated in recent years and that girls have better reading comprehension than boys. The basis for this study is Maj-Gun Johansson's reading comprehension test done during the four years between the years 2005-2008 in the seventh grade in a municipality in Sweden. The main purpose of this study is to examine reading literacy in terms of the influence of content and form of texts viewed from a gender perspective. The study is divided into two parts. The first part is a survey on local reading comprehension compared with results from a similar national text.

Begreppsbubblor/Visuella representationer i matematikundervisningen : En studie om bemötandets och undervisningens betydelse och möjligheter för elever med koncentrationssvårigheter
The aim is to examine how students with attention difficulties may demonstrate their mathematical understanding through visual representations. A curiosity about how students think about mathematics, national tests and Concepts cartoons has also permeated the study. With help of observations combined with interviews and actively work for a week, the study shows an idea of how visual representations can help students with concentration difficulties to stay focused on their tasks. I chose a selection of pupils to do some mathematical tasks from the national tests which they had not been able to solve before. Now in the form of Concepts cartoons, which I designed, they managed to solve the same mathematics data. In my study treatment and interaction reveals as key pillars for a successful educational work with the students with concentration difficulties. Thus, all pupils who previously have been unable to solve these assignments on the National test were now able to show their mathematical understanding supported by visual representations..
?Men snöbollarna är ju mer än tio!? : en vetenskaplig essä om matematik, lek och lärande i förskolan
My aim with the experience-based essay is that I want to explore the implications of mathematics on children's development. I also want to examine my approach in relation to the various mathematical tasks. Why do we think that mathematics is important for pre-school children? What does the research say about how the teacher is thinking about mathematics? Can the teacher combine playing and learning and create meaningful moments and activities related to mathematics? I also want to explore our policies and the objectives that the teacher should relate to. What is required of me as a teacher in order to meet those goals?My essay is about mine and my boss?s view of the mathematical tasks that I usually perform in the preschool.
