  1. 1. 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

  3. 2. Steg för steg. Naturvetenskapligt ämnesspråk som räknas

    Författare :Judy Ribeck; Lars Borin; Emma Sköldberg; Mats Wirén; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; academic language; computational linguistics; corpus linguistics; language technology; natural language processing; scientific language; subject-specific language; Swedish textbooks; quantitative stylistics; Svenska språket; Swedish;

    Sammanfattning : In this work, I present a linguistic investigation of the language of Swedish textbooks in the natural sciences, i.e., biology, physics and chemistry. The textbooks, which are used in secondary and upper secondary school, are examined with respect to traditional readability measures, e. LÄS MER

  4. 3. Does language matter? : sources of inequivalence and demand of reading ability of mathematics tasks in different languages

    Författare :Frithjof Theens; Ewa Bergqvist; Magnus Österholm; Lotta Vingsle; Andreas Ryve; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mathematics tasks; reading; equivalence; DIF; multilingual assessments; PISA; matematikdidaktik; didactics of mathematics; pedagogiskt arbete; educational work;

    Sammanfattning : Practicing mathematics is not possible without the use of language. To communicate mathematical content, not only words in natural language are used but also non-verbal forms of communication such as mathematical symbols, graphs, and diagrams. All these forms of communication can be seen as part of the language used when doing mathematics. LÄS MER

  5. 4. Modeling of bacterial DNA patterns important in horizontal gene transfer using stochastic grammars

    Författare :Mariana Buongermino Pereira; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Stochastic context-free grammars; hidden Markov model; conditional random fields; integrons; attC sites; secondary structure.; secondary structure.;

    Sammanfattning : DNA contains genes which carry the blueprints for all processes necessary to maintain life. In addition to genes, DNA also contains a wide range of functional patterns, which governs many of these processes. These functional patterns have typically a high variability, both within and between species, which makes them hard to detect. LÄS MER

  7. 5. On relations between classical and quantum theories of information and probability

    Författare :Peter Nyman; Andrei Khrennikov; Sergei Kozyrev; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Born’s rule; Clifford algebra; Deutsch-Josza algorithm; Grover’s algorithm; Hyperbolic interferences; Inverse Born’s rule problem; Probabilistic data; Quantum computing; Quantum error-correcting; Quantum-like representation algorithm; Shor’s algorithm; Simon’s algorithm; Simulation of quantum algorithms; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Sammanfattning : In this thesis we study quantum-like representation and simulation of quantum algorithms by using classical computers.The quantum--like representation algorithm (QLRA) was  introduced by A. Khrennikov (1997) to solve the ``inverse Born's rule problem'', i.e. LÄS MER
