  1. 1. Microstructural Changes in Deactivated Noble Metal Catalysts

    Författare :Bertil Stenbom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The structural deactivation of supported noble metal catalysts has been investigated for treatments at different temperatures and in different atmospheres. The sintering rates of Pt/Al2O3, Rh/Al2O3, and Pt-Rh/Al2O3 catalysts were measured using temperature-programmed desorption of CO (CO-TPD) and transmission electron microscopy (TEM). LÄS MER

  4. 3. Online coaching as a Relationship of Inquiry : Exploring one-to-one online education

    Författare :Stefan Stenbom; Stefan Hrastinski; Martha Cleveland-Innes; Inga-Britt Skogh; Elizabeth Murphy; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; online learning; online coaching; one-to-one online education; Community of Inquiry; Relationship of Inquiry; Teknikvetenskapens lärande och kommunikation; Education and Communication in the Technological Sciences;

    Sammanfattning : In educational development, much focus is put on the use of computers and other digital tools to enhance teaching and learning. One of the most used digital communication forms is one-to-one communication using text, images, and video. One-to-one communication for educational purposes has, however, so far received only modest attention in research. LÄS MER

  5. 4. Peer feedback with support of digital technology in visual art education

    Författare :Eva-Lena Forslind; Stefan Hrastinski; Ingrid Forsler; Stefan Stenbom; Fredrik Enoksson; Patrik Hernvall; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Peer feedback; digital technology; visual idea process; visual art education; K-12 education; Kamratfeedback; digitala verktyg; visuell idéprocess; bildämnet; grundskolan; Teknik och lärande; Technology and Learning;

    Sammanfattning : This licentiate thesis focuses on the development of the idea process in art education using digital peer feedback. In the school subject visual art, the visual idea process, e.g., when students sketch their ideas, is an important phase in a project. LÄS MER

  7. 5. Spontaneous online tutoring : Students’ support of their own and other students’ process of inquiry in online text-based tutoring

    Författare :Malin Jansson; Stefan Hrastinski; Stefan Stenbom; Fredrik Enoksson; Jennifer Richardson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teknik och lärande; Technology and Learning;

    Sammanfattning : The use of online technologies has made education more accessible. In online education, there are increased expectations for students to be self-directed and take responsibility for their learning. Research has also shown that students can benefit from learning from each other. LÄS MER
