良好的课前导语像戏剧的序幕,让学生心驰向往,像巨大的磁石,具有强大的作用力,让学生备受吸引,像投石于激浪之中,让学生启开思维的大门,点燃智慧的火炬。“良好的开端是成功的一半”。什么样的导语才算是好的导语呢?导语设计达到新奇性、达到艺术性、不乏知识性。导语设计的方法也是千姿百态、异彩纷呈的。选用哪一种方法,一般由教学内容所决定。 Good introductory precepts like a prelude to drama, so that students aspire to the heart, like a huge magnet, with a strong force, so that students are attracted, like throwing rocks in the waves, so that students open the door to thinking, light wisdom Torch. “Well begun is half done”. What kind of lead is regarded as a good lead? Lead design to achieve novelty, to artistic, there is no lack of knowledge. Lead language design methods are varied, colorful. Which method is used is generally determined by the teaching content.
