  1. 1. Learning in physics with simulation : Students’ needs & perceptions of the interaction with Algodoo, and learning in physics

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Seyma Ikra Koyuncu; [2023]
    Nyckelord :computational thinking; stem; simulations; physics; modelling; digital tools; digital content; computational thinking; stem; simulering; fysik; modellering; digitalt verktyg; digitalt innehåll;

    Sammanfattning : Initiatives to implement computational thinking and science, technology, engineering & modelling into learning processes have been taken by many authorities worldwide, and in Sweden as well. The Swedish government made changes in the high school curriculum in order to develop student’s digital competence including programming which has been in force since June 2018 (Skolverket, 2018).

  3. 2. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Klara Skoog; [2022]
    Nyckelord :Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

    Sammanfattning : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. LÄS MER
