Laborationsdesign för gymnasium och högskola
This thesis is about sustainability within chemistry, the so-called, green chemistry. With this work I seek to combine green chemistry with sustainable development and find methods for teaching green chemistry in a laboratory environement. I have designed and tested two labs …
Förberedelsens betydelse för gymnasieelevers lärande vid kemilaborationer
Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in …

Tema: Vitaminer och experiment
The aim of this study is to describe how a theme about vitamins and analytical chemistry can be planed and implemented in a summer research school managed by AstraZeneca. The description of the theme is intended to be used as an instructor’s guide to upcoming …
… aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus …
The aim of this study is to investigate how chemistry teachers at secondary school anduniversities work with learning strategies and models of perception. This thesis leans on theworks of Lev Vygotskij and his likes but also on the theory of conceptual metaphors by GeorgeLakoff …
