Sažetak
We presented the results of the interviews with nine Croatian high school students concerning their reasoning about electromagnetism (magnetic fields, Lorentz's force, electromagnetic induction, Lenz's law) at the first SEEMPE meeting. This time we will show preliminary results of the second part of the same investigation. Using the results of the interviews, we designed a questionnaire and administered it to 537 high school students in Croatia (aged 16-17) after they had learned about electromagnetic induction in their physics class. The questionnaire consisted of 15 multiple-choice questions and 7 open-ended questions. In the first step of the analysis, we used Rasch modelling to analyse the functioning of the multiple-choice part of the questionnaire. Our analysis shows that the questionnaire is well centred on students’ abilities. Item reliability indicates well defined difficulties of test items. However, person reliability warns us about some inconsistencies in the questionnaire. We plan to discuss the functioning of the multiple choice part of the research instrument to verify whether this questionnaire was an appropriate tool for determining students’ difficulties with electromagnetic induction. We will also discuss student difficulties with electromagnetic induction that were identified using the questionnaire and compare them with the difficulties identified through preliminary interviews.
