Abstract
The purpose of this study is to investigate primary teachers' understanding, and determine their awareness of students' ideas in the area of electric current. 315 primary teachers were asked to indicate their understanding and predict their students' answers in a questionnaire. Analysis of their responses reveal that most of the teachers understood the electric current of simple circuits in a 'scientifically acceptable' way, and identified all students' ideas. However, they were unable to predict with any accuracy the different types of students' ideas.
