(Menntavísindasvið Háskóli Íslands, 2016)Athugun á niðurstöðum í stærðfræði í PISA-rannsókninni 2003 sýndi að árangur nemenda í tveimur stærstu skólunum var marktækt betri en í minni skólum. Sérstaklega var árangurinn slakur í skólum með 11–25 þátttakendur. Athugun á árangri í dönskum skólum ... -
(Menntavísindasvið Háskóli Íslands, 2016-12-31)Landspróf miðskóla sem inntökupróf í menntaskóla og kennaraskóla og síðar fleiri skóla var haldið á árunum 1946–1976. Prófað var í átta námsgreinum þar sem íslenska vó tvöfalt. Landsprófið var upphaflega grundvallað á reglugerð nr. 3/1937 um námsefni ...

(American Physical Society (APS), 2018-08-27)We show that stable skyrmions with diameters of a few nanometers can emerge in atomic Pd/Fe bilayers on the Rh(111) surface. Based on density functional theory we calculate the exchange and the Dzyaloshinskii-Moriya interaction as well as the ...
-
(American Physical Society (APS), 2018-11-06)Various transitions that a magnetic Skyrmion can undergo are found in calculations using a method for climbing up the energy surface and converging onto first order saddle points. In addition to collapse and escape through a boundary, the method ...

(University of Iceland, School of Humanities, Faculty of History and Philosophy, 2018-05)In this thesis the ritual killing and burial of animals on grave-fields in Viking Age Iceland is critically re-evaluated, on a site-by-site basis, in order to characterize these customs and place them in a social and historical context. The foundation ...

(The Educational Research Institute, 2018-12-21)Í greininni er fjallað um sameiginlega hópleiðsögn þriggja leiðbeinenda meistaranema. Tilgangur rannsóknarinnar var að sýna fram á gildi þess að búa til námssamfélag nemenda og kennara um vinnu að meistaraprófsverkefni. Markmið rannsóknarinnar var að ...
-
(The Educational Research Institute, 2018-12-21)Rannsóknir sýna að lestraráhugahvöt hefur áhrif á ýmsar hliðar lestrarfærni, svo sem umskráningu, lesskilning og orðaforða. Börn með litla lestraráhugahvöt lesa minna en jafnaldrar með meiri lestraráhuga og sterk tengsl eru á milli slakrar lestraráhugahvatar, ...
