1. 1. Discovery-Oriented Screening of Dynamic Systems: Combinatorial and Synthetic Applications

   Författare :Marcus Angelin; Olof Ramström; Stefan Kubik; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical education; crystallization; dynamic combinatorial chemistry; dynamic combinatorial resolution; dynamic system; enzyme catalysis; isoindolinone; lipase; nitroalcohol; nitroaldol reaction; phthalide; reversible; secondary alcohol; systems chemistry; tandem reaction; Organic chemistry; Organisk kemi; Bioorganic chemistry; Bioorganisk kemi;

   Sammanfattning : This thesis is divided into six parts, all centered around the development of dynamic (i.e., reversibly interacting) systems of molecules and their applications in dynamic combinatorial chemistry (DCC) and organic synthesis. LÄS MER

3. 2. Kemistudenters föreställningar om entalpi och relaterade begrepp

   Författare :Tor Nilsson; Hans Niedderer; Kjell Waltersson; Roland Kjellander; Mälardalens högskola; []
   Nyckelord :enthalpy; thermodynamics; chemistry; chemistry education; conceptions; higher education; entalpi; termodynamik; kemi; kemididaktik; ämnesdidaktik; föreställningar; begrepp; begreppsbildning; högre utbildning; naturvetenskapernas och teknikens didaktik; naturvetenskapernas och teknikens didaktik;

   Sammanfattning : The aim of this thesis was to construct undergraduate chemistry students’ conceptions of enthalpy and its change, internal energy and its change, heat and work. Conceptions make it possible to identify students’ problems with the taught content. How students’ exam results are affected by qualitative/conceptual questions was also investigated. LÄS MER

4. 3. Supporting Learning and Teaching of Chemistry in the Undergraduate Classroom

   Författare :Ilana A. Manneh; Karim Hamza; Carl-Johan Rundgren; Lars Eriksson; Ingo Eilks; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; undergraduate chemistry education; learning and teaching processes; didactic triangle; chemical bonding; tutor-student interaction; practical epistemology analysis; continuity; progression; purposes; naturvetenskapsämnenas didaktik; Science Education;

   Sammanfattning : There is agreement in research about the need to find better ways of teaching chemistry to enhance students’ understanding. This thesis aims to contribute to the understanding of how we better support teaching and learning of undergraduate chemistry to make it meaningful and intelligible for students from the outset.
