A Method for Investigating Concept Understanding in Science

Abstract
English The authors report on an ‘Interview about instances’ technique for the investigation of students’ concept understanding in science. The potential and limitations of this technique has been explored in relation to the concepts ‘work’ and ‘electric current’ in 50 trial interviews involving students over the age range seven to 18 years. Some of the findings are reported here and suggestions made for further studies using the ‘Interview about instances’ technique.
