1. 1. Top Quark Pair Production in ATLAS

   Författare :Karl Gellerstedt; Jörgen Sjölin; Kerstin Jon-And; Cecilia Gerber; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark; LHC; ATLAS; fysik; Physics;

   Sammanfattning : The Large Hadron Collider (LHC) at the international particle physics laboratory CERN in Switzerland is currently the most powerful particle accelerator on earth. This thesis presents analyses of proton-proton collisions at the energy √s = 7 TeV, recorded by ATLAS, one of the detectors at the LHC. LÄS MER

3. 2. Mathematical Reasoning in Physics Tests : Requirements, Relations, Dependence

   Författare :Helena Johansson; Mats Andersson; Jesper Boesen; Kerstin Pettersson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical reasoning; imitative reasoning; creative mathematical reasoning; physics tests; physics tasks; upper secondary school; Mantel-Haenszel procedure; Mathematical reasoning; imitative reasoning; creative mathematical reasoning; physics tests; physics tasks; upper secondary school; Mantel-Haenszel procedure.; Mantel-Haenszel procedure;

   Sammanfattning : By analysing and expanding upon mathematical reasoning requirements in physics tests, this licentiate thesis aims to contribute to the research studying how students’ knowledge in mathematics influence their learning of physics. A sample of physics tests from the Swedish National Test Bank in Physics was used as data, together with information of upper secondary students’ scores and grades on the tests. LÄS MER

4. 3. A classifying algebra for CFT boundary conditions

   Författare :Carl Stigner; Jürgen Fuchs; Alexei Semikhatov; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary conditions; Conformal field theory; Factorization constraints; Modular tensor categories; TFT-construction; Mathematical physics; Matematisk fysik; Physics; Fysik;

   Sammanfattning : Conformal field theories (CFT) constitute an interesting class of twodimensionalquantum field theories, with applications in string theoryas well as condensed matter physics. The symmetries of a CFT can beencoded in the mathematical structure of a conformal vertex algebra. LÄS MER

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

   Författare :Helena Johansson; Mats Andersson; Jesper Boesen; Morten Blomhøj; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Creative mathematical reasoning; Descriptive statistics; Differential item functioning; Figurative context; Imitative reasoning; Mathematical Reasoning Requirements; Mathematics tasks; National tests; Physics tasks; Real-life context; T-test; Upper secondary school; Creative mathematical reasoning; Descriptive statistics; Differential item functioning; Figurative context; Imitative reasoning; Mathematical Reasoning Requirements; Mathematics tasks; National tests; Physics tasks; Real-life context; T-test; Upper secondary school;

   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

7. 5. Fysik, lärande samtal och genus. : En studie av gymnasieelevers gruppdiskussioner i fysik

   Författare :Karin Due; Sylvia Benckert; Britt-Marie Berge; Svein Sjøberg; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; physics education; science education; gender; group discussions; upper secondary school; sociocultural theory; discourse analysis; images of physics; Fysikdidaktik; naturvetenskapernas didaktik; genus; gruppdiskussioner; gymnasieskolan; sociokulturell teori; diskursanalys; föreställningar om fysik; lärande; Subject didactics; Ämnesdidaktik;

   Sammanfattning : This thesis investigates how students in upper secondary school solve problems and discuss physics in small groups. The study examines how gender, knowledge in physics and the image of the subject physics are constructed in the students’ conversation and how these processes are related to each other. LÄS MER
