人常说:良好的开端是成功一半,可见一堂新课的引入是何等的重要。它能激发学生兴趣和情感、启发和引导学生的思维,让学生很快进入教学最佳状态。好的引入如同桥梁,联系新课和旧课;如同序幕,预示后面高潮和结局;如同路标,引导学生思维方向;为整堂课打好基础,奠定整个课堂教学艺术成功的基调。但它没有固定的模式,方法是多种多样的。 People often say that a good start is half success, showing how important a new lesson is. It can stimulate students ’interests and emotions, inspire and guide students’ thinking, so that students can quickly enter teaching best. Good introduction as a bridge, contact the new class and the old class; as the prelude, predicting the climax and ending behind; like a signpost to guide students thinking direction; lay the foundation for the entire class, lay the tone of the classroom teaching art success. But it does not have a fixed pattern, the method is varied.
