  1. 1. Statistical modeling in international large-scale assessments

    Författare :Inga Laukaityte; Marie Wiberg; Kenny Bränberg; Ewa Rolfsman; Bernard Veldkamp; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilevel model; plausible values; sampling weights; missing information; multiple imputation; non-monotone missing pattern; TIMSS; PISA; Statistics; statistik; pedagogik; Education;

    Sammanfattning : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.

  3. 2. Robust large-scale mapping and localization : Combining robust sensing and introspection

    Författare :Daniel Adolfsson; Henrik Andreasson; Martin Magnusson; Stephanie Lowry; Timothy Barfoot; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SLAM; Localization; Robustness; Radar;

    Sammanfattning : The presence of autonomous systems is rapidly increasing in society and industry. To achieve successful, efficient, and safe deployment of autonomous systems, they must be navigated by means of highly robust localization systems. LÄS MER

  4. 3. Kan man räkna med PISA och TIMSS? : Relevansen hos internationella storskaliga mätningar i matematik i en nationell kontext

    Författare :Samuel Sollerman; Astrid Pettersson; Lovisa Sumpter; Christian Lundahl; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International large-scale assessment; Mathematics; Validity; Validation; Relevance; Assessment; PISA; TIMSS; Mathematics education; matematikämnets didaktik; Mathematics Education;

    Sammanfattning : The overall purpose of the thesis is to contribute to the knowledge of relevance of international large-scale assessments (ILSAs) in mathematics, when these are to be used and interpreted in a national context. If a nation is to engage in ILSAs, draw conclusions from them and act on them, one should be aware of what they are measuring and how well it fits in with the national mathematics education and the mathematics they are trying to teach their students.

  5. 4. Sustainable Land and Water Management for a Greener Future : Large-scale insights in support of Agroecological Intensification

    Författare :Luigi Piemontese; Fernando Jaramillo; Maria Cristina Rulli; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : The challenge of producing more food in times of climate change, degraded land and scares water resources is calling for a radical transformation of agriculture. Sustainable agricultural intensification is the process of increasing the productivity of farms while preserving functional ecosystems. LÄS MER

  7. 5. International large-scale assessments and mathematics textbooks in a curriculum reform process : Changes in lower secondary school algebra in Sweden 1995–2015

    Författare :Kristina Palm Kaplan; Johan Prytz; Kajsa Bråting; Astrid Pettersson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; curriculum reform; algebra; textbooks; international assessment; TIMSS; secondary school; test validity; student achievement.; Curriculum Studies; Didaktik;

    Sammanfattning : Reforming a curriculum entails more than simply launching new steering documents: it includes the development of new materials, evaluation of reform and identification of needs for further action. Drawing from algebra material surrounding the 2011 Swedish curriculum reform, this thesis contributes to understanding the process of curriculum reform concerning mathematics textbooks and international large-scale assessments.
