  1. 11. Seeing the parts, understanding the whole : A technology education perspective on teaching and learning in processes of analysing and designing programmed technological solutions

    Författare :Anne-Marie Cederqvist; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; technology education; programmin; programmed technological solutions; programming materials; phenomenography; LeaDS - Learning in a Digitalised Society; LeaDS - Lärande i ett digitalt samhälle; technology education; programming; programmed technological solutions; programming materials; phenomenography;

    Sammanfattning : Analysing and designing Programmed Technological Solutions (PTS) has been introduced as a part of technology education in an effort to bring elements of programming into the curriculum for compulsory school, in order to develop pupils’ understanding of how PTS work and are controlled by programming. However, what an appropriate understanding entails at this level remains to be articulated, particularly how this understanding looks from a pupil’s perspective. LÄS MER

  3. 12. Models of Cooperation, Learning and Catastrophic Risk

    Författare :Vilhelm Verendel; Chalmers tekniska högskola; []

    Sammanfattning : Our world presents us with dangers and opportunities. Some of these dangers and opportunities are easier to handle if two or more individuals learn to cooperate. This thesis contributes five papers about cooperation, learning and catastrophic risk. LÄS MER

  4. 13. Communicating, Measuring and Preserving Knowledge in Software Development

    Författare :Conny Johansson; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Software Engineering is a rapidly changing area, especially in terms of its technological foundation. The computer and information technology changes both the kind of systems to be built and the methods and tools available with which to build them. LÄS MER

    Sammanfattning : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. LÄS MER

  7. 15. Low temperature CO oxidation: Effects of support, composition and structure

    Författare :Noemi Bosio; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Carbon monoxide is a tasteless, colorless and in-odorous toxic gas, which is formed during incomplete combustion. Due to its toxicity, efficient methods for CO oxidation to CO2 are required. LÄS MER
