Partikelmodell som utgångspunkt för elevers förklaringar av avdunstning

Abstract [en]

This paper presents results from a longitudinell study of students in compulsary school in Sweden. The project started in 1997 when the students were about six years old, and finished in 2006 when they left compulsary school. The aim of the study is to follow individual students’ development of conceptions about evaporation during their years in school. Teaching episodes focused on water, and it´s changes of state connected to everyday phenomena have been taught. Early in the study a simplified particle model was introduced in order to see if this would help the students in their explanations. The students were interviewed before and after the teaching interventions and the explanations were analysed in order to find a comprehensive description of each student. Here we describe the use of the early introduced particle concept and how it effects the students’ explanations of evaporation and their uses of explanatory models.

Abstract [en]

This thesis presents results from a longitudinal study of students in compulsory school. The project started in spring 1997 when the students were about six years old, and finished in spring 2006 when they left compulsory school. One aim of the study was to follow individual students' development of conceptions about evaporation during their year in scool. Another aim has been to study how the students used a simplified particle model in their explanations of evaporation. The particle model was introduced early, in their first year. Teaching episodes focused on water, and its changes of state connected to everyday phenomena was taught. The students were interviewed before and after the teaching interventions and the explanations were analysed in order to find a comprehensive description of each student. In my analysis I have among other things found that heat is an important factor for evaporation when students are young but its importance seems to decrease when they get older. I have also seen that particle model has been helpful for the students in their explanations of evaporation.

Abstract [sv]

Denna avhandling presenterar resultat från en longitudinell studie i grundskolan. Projektet startade våren 1997 då eleverna var omkring sex år och avslutades våren 2006 då eleverna lämnade grundskolan. Ett mål med studien var att följa individuella elevers begreppsutveckling kring avdunstning under deras år i skolan. Ett annat mål har varit att studera hur eleverna har använt en tidigt introducerad förenklad partikelmodell i sina förklaringar av avdunstning. Undervisningsinsatser som fokuseras på vatten och dess fasändringar kopplat till vardagsfenomen har genomförts. Eleverna har intervjuats före och efter varje insats och förklaringarna har analyserats för att få en heltäckande beskrivning vad gäller begreppsutvecklingen hos varje elev. I min analys har jag bl.a. funnit att värme är av stor betydelse för de yngre eleverna i deras förklaringar av avdunstning men att denna betydelse minskar då eleverna blir äldre. Jag har också sett att den tidigt introducerade partikelmodellen har varit ett bra hjälpmedel för eleverna i deras förklaringar av avdunstning.
