中文摘要：

当前我国工科院校的电气类专业课程都是采用理论和实验教学分开设置的模式,学生不能及时理解和体会专业理论知识的应用,这在一些实践性较强的电气类专业课中体现的尤为明显。针对这类问题,本文提出了一种理论和实践一体化的启发式案例教学法用于课堂教学。该方法根据现有的实验设备选择契合教学内容的工程应用案例。课堂上,先将案例相关的理论知识大致介绍一遍,然后马上在课堂上进行现场实验,结合实验再详细讲述相关理论,并在此过程中和学生进行启发式互动,实现理论和实践教学的无缝融合。教学实践表明,该方法可以活跃课堂气氛,提高教学效率,深化学生对专业理论知识的理解和应用。

英文摘要：

The theory and practical teaching is set respectively for electrical courses of engineering colleges, which makes the students unable to fully understand the theory and its applica-tion of electrical courses, especially for those practical electri-cal courses. To solve these problems, a heuristic case teaching method in which the theory teaching and practical teaching are integrated within classroom is proposed in this paper. The en-gineering application case which coincides with the teaching contents is selected according to the existing laboratory equip-ment. The related theory of cases is introduced firstly, then the in-situ experiment is presented immediately in classroom while the theory is explained again in detail. The heuristic interaction with students is done from beginning to end, which is helpful for seamless combination of theory teaching and practical teaching. Teaching practices demonstrated that this method can create active classroom atmosphere, improve the teaching effective-ness, and make the students understand the professional theory knowledge and its application better.
