Özet (Çeviri)

In recent years, a large amount of research in science education has investigatedstudents? alternative conceptions about various science topics. In physics education, themain focus of these investigations has been on mechanics and electricity. By contrast,relatively little research has been carried out on electromagnetism. The aim of thisstudy was to investigate students? understanding of electromagnetism at the levelcorresponding to upper secondary school courses (students aged 16-18) in Turkey andEngland.The study employed a written diagnostic test and interviews, to investigate around 100students? understanding and reasoning in each country. The study sought to identify theelectromagnetism topics that pose significant learning difficulties, evidence of`alternative frameworks? of understanding, and the relationship between success inelectromagnetism and students? ability in spatial and proportional reasoning. Studentresponses were analysed to reveal underlying patterns, and consistency betweenquestions testing the same idea. Correlation between performance onproportional/spatial reasoning questions and on the electromagnetism questions wasexplored. Interviews were conducted with about twenty Turkish students, to check thatstudents have understood the questions, that our interpretation of their responses isvalid, and to probe alternative responses in more depth.Findings suggest that many students do not have an integrated framework of ideas aboutelectromagnetism. Students in both samples showed similar misconceptions aboutmany ideas of electromagnetism. Main sources of difficulties in understandingelectromagnetism were: (1) inappropriate analogies with the effects of an electric fieldon charges, (2) flow interpretation of magnetic field, (3) the experiential gestalt ofcausation, (4) difficulty in handling the idea of rate of change of magnetic flux, and (5)the visualisation of 3D situations from their 2D representations. Explicit teaching ofthese points, or more emphasis (and time) on these during instruction, might help toimprove students? understanding and performance.
