1. 1. The function concept and university mathematics teaching

   Författare :Olov Viirman; Iiris Attorps; Barbara Jaworski; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mathematics; university education; commognitive framework; function concept; discourse; teaching; Matematik; Mathematics;

   Sammanfattning : This thesis concerns the teaching of mathematics at university level, with a particular focus on the teaching of the function concept. The main aim of the thesis is describing and analysing the teaching practices of university mathematics teachers regarding the function concept, and how this concept is constituted through these practices.

3. 2. Generalized Vandermonde matrices and determinants in electromagnetic compatibility

   Författare :Karl Lundengård; Sergei Silvestrov; Dietrich von Rosen; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : Matrices whose rows (or columns) consists of monomials of sequential powers are called Vandermonde matrices and can be used to describe several useful concepts and have properties that can be helpful for solving many kinds of problems. In this thesis we will discuss this matrix and some of its properties as well as a generalization of it and how it can be applied to curve fitting discharge current for the purpose of ensuring electromagnetic compatibility.

4. 3. Models for capturing the penetration of a diffusant concentration into rubber : Numerical analysis and simulation

   Författare :Surendra Nepal; Adrian Muntean; Nadja Ray; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transport of diffusants; moving-boundary problem; finite element method; a priori and a posteriori error estimates; random walk method; two-scale coupled system; Matematik; Mathematics;

   Sammanfattning : Understanding the transport of diffusants into rubber plays an important role in forecasting the material's durability. In this regard, we study different models, conduct numerical analysis, and present simulation results that predict the evolution of the penetration front of diffusants. LÄS MER

5. 4. Syllogistic Analysis and Cunning of Reason in Mathematics Education

   Författare :Yang Liu; Arne Engström; Jiansheng Bao; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics education; mathematics teaching; syllogistic analysis; cunning of reason; change of perspective; didactic transposition; classroom instruction; textbook writing; Matematik; Mathematics;

   Sammanfattning : This essay explores the issue of organizing mathematics education by means of syllogism. Two aspects turn out to be particularly significant. One is the syllogistic analysis while the other is the cunning of reason. LÄS MER

7. 5. Difficult to read or difficult to solve? : The role of natural language and other semiotic resources in mathematics tasks

   Författare :Anneli Dyrvold; Magnus Österholm; Ewa Bergqvist; Johan Lithner; Candia Morgan; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; multisemiotics; task text; difficulty; mathematical reading ability; matematikdidaktik; didactics of mathematics; Mathematics; Pedagogik; Linguistics;

   Sammanfattning : 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. LÄS MER
