    Abstract : Despite considerable expansion in the scope and function of the state with respect to environmental protection, the world’s biological diversity and ecosystem services continue to deteriorate. Finding ways to better govern human-nature relations in cities is an important part of addressing this decline. READ MORE

  6. 4. Bilingual students' learning in science : Language, gestures and phyiscal artefacts

    Author : Zeynep Ünsal; Britt Jakobson; Per-Olof Wickman; Bengt-Olov Molander; Erik Knain; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; science education; bilingual students; mediating means; language; gestures; physical artefacts; learning; meaning-making; practical epistemological analysis; translanguaging; continuity; naturvetenskapsämnenas didaktik; Science Education;

    Abstract : The objective of this thesis is to examine how language, gestures and physical artefacts are used in science classes with emergent bilingual students who do not share the same minority language as their classmates or teachers. The purpose is to contribute to findings that can enhance emergent bilingual students’ learning in science. READ MORE

  7. 5. Computer Science Project Courses : Contrasting Students’ Experiences with Teachers’ Expectations

    Author : Mattias Wiggberg; Mats Daniels; Lecia J. Barker; Tony Clear; Uppsala universitet; []
