一、激发兴趣时巧妙出示著名特级教师于漪有一句名言:“课的第一锤要敲在学生的心灵上,激发起他们思维的火花,好像磁石一样把学生牢牢地记住”。新颖巧妙的开头是上好一堂课的关键,是教师与学生沟通的第一桥梁。紧扣教材合理利用电教设备,创造逼真的影视氛围,并加以恰当地质疑,引导学生在浓厚的兴趣中开展思维。这样学生就会在轻松愉快的气氛中进入学习状态,自觉地把注意力转向教学内容。例如:在讲解《细胞中的无机物》这节课时,我以视频(播放姚明拍摄的佳得乐饮料广告)导入, First, when inspiring interest, it is wise to show that a well-known special teacher has a famous saying: “The first hammer of the lesson is to knock on the students’ minds, inspiring the spark of their thoughts, as if the magnets had firmly remembered the students.” . The novel and clever beginning is the key to a good class and is the first bridge between teachers and students. The teaching materials are closely tied to the use of audio-visual equipment to create a realistic atmosphere of film and television. They are properly questioned and guide students to think in a strong interest. In this way, the students will enter the learning state in a relaxed and happy atmosphere and consciously turn their attention to the teaching content. For example, when I was explaining the inorganic substance in the cell, I imported it as a video (playing a Gatorade beverage advertisement shot by Yao Ming).
