电和磁的概念调查（CSEM）涵盖了一个大的概念领域，并为比较电和磁的不同概念领域的困难提供了很多机会。 CSEM 中确定了六个概念领域，每个概念领域由四到六个问题组成。 CSEM 是对萨格勒布大学基于微积分的普通物理课程的 84 名克罗地亚学生进行的后测。将六个概念领域的平均难度与参加基于代数或基于微积分的普通物理课程的美国学生的相同概念领域的平均难度进行比较。三组学生在概念领域的困难表现出相似的趋势。最困难的领域是电磁感应，其次是电和磁中的牛顿定律，以及电势和能量。前测和后测结果的比较表明，...
The Conceptual Survey of Electricity and Magnetism (CSEM) covers a large conceptual domain and gives many opportunities for comparing the difficulties of different conceptual areas in electricity and magnetism. Six conceptual areas were identified in the CSEM that are represented by groups of four to six questions each. The CSEM was administered as a posttest to 84 Croatian students in a calculus-based general physics course at the University of Zagreb. The average difficulties in the six conceptual areas were compared to the average difficulties of the same conceptual areas of American students enrolled in algebra-based or calculus-based general physics courses. The difficulties of the conceptual areas show similar trends for the three groups of students. The most difficult area was found to be electromagnetic induction, followed by Newton’s laws in the context of electricity and magnetism, together with the electric potential and energy. The comparison of pretest and posttest results suggests that instr...
