  1. 11. Farm-based education : can farms and farm animals contribute to learning in accordance with the school curriculum and syllabi?

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Malin Larsson; [2022]
    Nyckelord :farm-based education; educational farms; experiential learning; embodiment; embodied learning; outdoor education; animal-assisted education;

    Sammanfattning : There seems to be something missing in the modern school. An increasing number of students face difficulties in the traditional classroom setting, some cannot attend school at all, and a worrying number of students fail to leave school with approved grades, with potentially detrimental effects on their future lives.

  3. 12. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects

    Master-uppsats, Lunds universitet/Matematisk fysik

    Författare :Josefin Reftlér; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. LÄS MER

  4. 13. Policy eller person? : En intervjustudie om varför vissa kommunala styren upplöses i förtid, medan andra lyckas hålla ihop.

    Sammanfattning : Why do some governing coalitions terminate during the term of office, while others manage to stick together until the next election? That is the question this essay tries to answer. According to previous research of coalition termination, the structural attributes of the coalition in terms of for example majority status, minimal winning status, and numbers of parties in the party system, matter for the stability of coalitions.

  5. 14. Prospective Life Cycle Assessment of an Electrochemical Hydrogenation Process Over a Nickel Foam Cathode

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hanson Appiah-Twum; [2022]
    Nyckelord :Scale-up; early process design; catalysis; environmental impact; hotspot analysis; green chemistry;

    Sammanfattning : The need for a safe and sustainable chemical industry has called for the development of emerging technologies with improved environmental performance. In this study, an emerging electrochemical hydrogenation process over Ni foam is being developed at the laboratory scale with an expectation of less environmental impacts than a conventional palladium on carbon hydrogenation process.

  7. 15. NATURVETENSKAPENS KARAKTÄR OCH EPISTEMOLOGISK LEGITIMERING - Möjligheter till undervisning utifrån styrdokument och läroböcker

    Master-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk profession

    Författare :Johan Espenberg; [2021-09-15]
    Nyckelord :upper secondary school; nature of science; justification of knowledge; textbook; curriculum; content analysis;

    Sammanfattning : Aim: The purpose of this master thesis is to examine the occurrence of nature of science (NOS), and the justification of scientific knowledge, in school science textbooks and curriculum documents for upper secondary school (year 10 – 12) in Sweden. There are a lot of research about science textbooks and NOS which tells us that the coverage and quality of NOS-content often are poor. LÄS MER
