The electric circuit : An explonary study with students in the age of eleven and fifteen and students who have studied the first course in physics (Fysik A), focusing on the electric circuit and its components (English)
Abstract [sv]

Studien har utvecklats som en del av ett samarbete mellan Taiwan, Finland och Sverige där avsikten är att jämföra elever i olika åldrars uppfattningar angående elektriska kretsar. Syftet med den här kvalitativa studien är att ta reda på vilka uppfattningar svenska elever i olika åldrar har angående den elektriska kretsen. Studien har genomförts med hjälp av semi-strukturerade intervjuer. Totalt har nio elever i år 5, i år 9 och på gymnasiets 3:e år intervjuats. Intervjuerna har analyserats dels utifrån Kärrqvists (1985) förklaringsmodeller som elever har uppvisat angående elektriska kretsar och dels med hjälp av en fenomenografisk metod. Resultatet visar bland annat att tre modeller återfinns bland respondenterna. En respondent uppvisade en ny modell som inte överensstämmer med Kärrqvists (1985) förklaringsmodeller. Den nya modellen har fått namnet kopplingsberoende modell. Analysen visar också att elever kan tillämpa konceptet sluten krets samt att elever beskriver elektriska kretsar genom att prata om sladdarna i kretsen. Eleverna försökte motivera svaren på frågorna genom att föra ett resonemang om sladdar. Studien visar även att eleverna inte kan ge fullständiga förklaringar om elektriska komponenters funktion.

Abstract [en]

This study has developed as a part of an ongoing co-operation between Taiwan, Finland and Sweden with the purpose of examining and comparing the conceptions of students of different ages concerning electric circuits. The purpose of this qualitative study is to find out what conceptions Swedish students of different ages have concerning the electric circuit. The study has been accomplished by means of semi-structured interviews. Altogether nine students in the age of eleven, fifteen, seventeen and eighteen have been interviewed. The interviews have been analyzed partly from Kärrqvist’s (1985) models that students have shown regarding electric circuits and partly by means of a phenomenographic method. The result inter alia demonstrates that three models are to be found among the respondents. One respondent showed a new model, which does not correspond to Kärrqvist’s (1985) models. The new model has been named “kopplingsberoende modell” (connection-dependent model). The analysis also shows that students know how to apply the concept of a closed circuit and that students describe electric circuits by discussing the wires of the circuit. The students tried to confirm the answers to the questions by discussing the wires. The study further shows that the students cannot give complete explanations to the function of electric components.
