  1. 1. The Potential and Challenges of the Use of Dynamic Software in Upper Secondary Mathematics : Students’ and Teachers’ Work with Integrals in GeoGebra Based Environments

    Författare :Sanela Mehanovic; Per Jönsson; Morten Blomhøj; Per-Eskil Persson; Morten Misfeldt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : An introduction of computer software into mathematics classrooms makes the didactical situation more complex compared with previous learning environments (Blomhøj, 2005). A technological tool becoming a mathematic work tool in the hands of the students is a process that has turned up unexpectedly complex (Artigue, 2002). LÄS MER

    Författare :Tomas Bergqvist; Hans Wallin; Johan Lithner; Morten Blomhøj; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Explorations; mathematical reasoning; empirical investigations; graphing calculators; conjectures.; Subject didactics; Ämnesdidaktik; MATHEMATICS; MATEMATIK; didactics of mathematics; matematikdidaktik;

    Sammanfattning : 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. LÄS MER

  4. 3. Mathematical Reasoning : In physics and real-life context

    Sammanfattning : This thesis is a compilation of four papers in which mathematical reasoning is examined in various contexts, in which mathematics is an integral part. It is known from previous studies that a focus on rote learning and procedural mathematical reasoning hamper students’ learning of mathematics. LÄS MER

  5. 4. Representationer, visualisering och resonemang i geometri : Praktiknära studier i digitala lärmiljöer

    Författare :Peter Markkanen; Per Nilsson; Andreas Eckert; Constanta Olteanu; Morten Blomhøj; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geometry; visualization; representations; reasoning; digital tools; design research;

    Sammanfattning : The aim of this dissertation was to gain a deeper understanding of how teaching in digital environments can be designed to give students opportunities to develop knowledge in two- and three-dimensional geometry. The dissertation consists of two sub-studies, the first using an ethnographic approach in which the researcher followed a teacher's teaching in a digital environment, in a Grade 9 class for a period of five weeks.
