Abstract [sv]

Den här studien berör fotosyntesen som undervisningsmoment. Till studien har ett undervisningsmoment utvecklats som behandlar de kemiska processerna i fotosyntesen. Övningen är ett tillägg till skolprogrammet Regnskogsträd eller Ökenväxter i Edvard Andersons växthus. Ett skolprogram är en pedagogisk aktivitet och just det här programmet erbjuds av Naturens Hus till både grundskoleelever och gymnasieelever. Naturens Hus är en del av Vetenskapens Hus som håller i undervisning i de naturvetenskapliga ämnena med målet att inspirera elever till fortsatta studier i de naturvetenskapliga ämnena. I utvecklingsarbetet av övningen har målet varit att framställa ett tillägg till nämnda skolprogram som kan komplettera undervisningen av fotosyntesen i gymnasiekurserna Biologi 2 och Kemi 2. För att kunna utforma ett kompletterande pedagogiskt material har dessutom en studie gjorts kring olika didaktiska teorier. Dels har en undersökning kring hur Bernsteins teorier kring klassificering och inramning kan anas i undervisningen av fotosyntesen gjorts. Klassificering innebär hur gränsen är dragen mellan skolämnena och inramning innebär vem som har kontrollen i klassrummet. Dels har en undersökning av olika läromedel i de olika kurserna genomförts och diskuterats i samband med hur läromedelstyrning påverkar undervisningen. Resultatet från studien visar att det finns en stark klassificering mellan kemi och biologi som ämne men att i just detta område, som kan klassas som biokemi, så är gränsdragningen mindre stark. Vad gäller läromedel så är det ett antal begrepp som enbart omnämns i biologiläroböckerna och att de avsnitt som berör fotosyntesen i kemiläroböckerna har placerats i fördjupningsdelar eller fördjupningskapitel.

Abstract [en]

This is a study concerning photosynthesis as a school subject. A part of the study has been to develop an addition to a school program that regards the chemical processes in the photosynthesis. The school program’s name is Regnskogsträd eller Ökenväxter i Edvard Andersons växthus which translates to Rainforest trees or Desert plants in Edvard Andersons greenhouse. A school program is a pedagogic activity and this program in particular is offered by the House of Nature to students of all ages, from Primary School to Upper Secondary School. The House of Nature is a part of The House of Science that offers natural science teaching with the aim of inspiring students to continue their studies within the natural science field. The goal of the development process has been to create additional material that can complement the teaching of photosynthesis in the courses Biologi 2 and Kemi 2, translated to Biology 2 and Chemistry 2, studied by upper secondary school students. To be able to create a complementing addition a study regarding different didactical theories has been made. Partly a research regarding the theories from Bernstein, classification and framing, and their visibility in the teaching of photosynthesis has been investigated. Where classification stands for the degree of boundaries between the two school subjects and framing stands for who has the control in the classroom. Partly a research regarding the teaching material of the same courses has been made and the results have been discussed in connection with theories of how the teaching material can control what is taught in school. The result from the research shows that there is a strong classification between chemistry and biology as school subject but that concerning the subjects of biochemistry the demarcation is weaker. Regarding the teaching material, several concepts are only mentioned in the biology literature and the sections that concerns photosynthesis in the chemistry literature has been placed in the advanced knowledge chapters.
