摘　　要：德识才学是科学人才的必备素养,其中“识”是指见识、见解、眼光,是一种高瞻远瞩、预见事物发展方向的能力.本文介绍电动力学教学中四个“识”的引导,一是善于大胆设想并小心求证,二是善于用实验检验科学设想,三是善于从矛盾中发现新事物,四是善于运用数学进行物理逻辑推理.这四个“识”基于科学史实,借助科学巨匠的榜样力量,有机融入麦克斯韦方程理解和应用的教学实践之中,旨在引导学生的科学观.在华中师范大学“国家基础科学研究与教学人才培养基地”(物理学)实施的情况表明,四个“识”的引导可以帮助学生增强电动力学学习的兴趣和毅力,提升未来综合发展的信心和潜力.Morality and principle,insight and idea,ability and competence,knowledge and experience constitute four requisite qualities for a scientific talent.Of them,insight and idea mean capability to look far ahead and to make a foresight.In this article four elements are described to be inspired for insight and idea in the teaching practice of Electrodynamics.The first is to be good at giving an idea daringly and proving it carefully;the second is to be good at testing and verifying an idea experimentally;the third is to be good at discovering something new from a contradictory;the forth is to be good at using mathematics for physical reasoning.The inspiration of these four elements is based on the historical facts in science.It depends on the great scientists as examples,it is blended with Maxwell equations’understanding and applications,and it is aimed at the scientific view guidance to the students.The teaching practice of it,which has been carried out at national base for training talents for research and teaching in fundamental science(physics)at Central China Normal University,has demonstrated that it helps students promote their interest and perseverance for the Electrodynamics learning and enhance their confidence and potential for their future comprehensive development.
