2. 1. Designing for added pedagogical value : A design-based research study of teachers’ educational design with ICT

   Author : Jörgen Holmberg; Uno Fors; Göran Fransson; Jo Tondeur; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; added pedagogical value; design-based research; design framework; educational design; educational design research; EFL; ICT; teacher practice; TPACK; Information Society; informationssamhället; Innovative Learning;

   Abstract : In an increasingly digitized world teachers are expected to take on the role of educational designers and use ICT to design in ways that add pedagogical value to teaching and learning. This thesis adopts a design-based research (DBR) approach to: (a) explore and contribute to the educational design processes of teachers of English as a foreign language in their efforts to use ICT for added pedagogical value, (b) examine how ICT is used in educational designs to create/contribute to what the teachers and students describe as added value and (c) explore, problematize and refine DBR as a research approach.

5. 3. Wind Power - Added Value for Network Operation

   Author : Nayeem Ullah; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torsional oscillation; reactive power ancillary service; voltage stability; power system simulator.; STATCOM; non-minimum phase system; Variable speed wind turbine; frequency control; sensitivity analysis; transient stability; small-signal stability;

   Abstract : This dissertation deals with the investigation on different value added properties of variable speed wind turbines (VSWT) that stem from the flexible controllability of converter interfaced wind turbines (WT). Improvements in voltage and transient stability of a nearby grid, small-signal stability improvement on the power system, frequency control support for the network operation, as well as thetechnical and the economic issues related to the reactive power ancillary service provision, are among the issues covered.
