  1. 1. The Inefficient Loneliness : A Descriptive Study about the Complexity of Assessment for Learning in Primary Technology Education

    Författare :Eva Hartell; Inga-Britt Skogh; Edvard Norlander; Lena Gumaelius; Pernilla Nilsson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; technology education; assessment; formative assessment; assessment for learning; primary education; teknikundervisning; bedömning; formativ bedömning; bedömning för lärande; individuella utvecklingsplaner med skriftliga omdömen; iup; grundskola; vurdering for laring;

    Sammanfattning : This thesis provides findings from a qualitative study that explores the assessment process undertaken by teachers in Swedish primary technology education. The thesis aims to contribute to a deeper understanding of how teachers assess in technology education. LÄS MER

  3. 2. Mechanical and swelling properties of hydrogels

    Författare :Ting Yang; Anders Hult; Michael Malkoch; Jöns Hilborn; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Hydrogels have been used as one of the novel soft materials in many biomedical applications such as drug delivery and tissue engineering for recent decades.In the main part of this work, bi-functional poly(ethylene glycol) (PEG) precursors with either thiols (PEG-SH) or allyls (PEG-Al) , covering molecular weights from 3 kDa to 8 kDa were synthesized and thoroughly characterized by 1H NMR, 13C NMR, FT-Raman and MALDI-TOF techniques.

  5. 4. Flow measurements using combustion image velocimetry in diesel engines

    Författare :Henrik Dembinski; Hans-Erik Ångström; Paul Miles; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This work shows the in-cylinder airflow, and its effects on combustion and emissions, in a modern, heavy-duty diesel engine. The in-cylinder airflow is examined experimentally in an optical engine and the flow field inside the cylinder is quantified and shown during combustion, crank angle resolved. LÄS MER

  7. 5. Mold2012 : a new gravimetric quasigeoid model over Moldova

    Författare :Uliana Danila; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geoid; quasigeoid; KTH method; corrective surface;

    Sammanfattning : In order to be able to use the operational Moldavian GNSS Positioning System MOLDPOS efficiently for the determination of normal heights in surveying engineering, e.g. during the construction of a road, an accurate quasigeoid model is needed. LÄS MER
