过去一提到数学课,学生就会联想到“枯燥”、“乏味”、“机械训练”这些词儿。自从信息技术进入课堂,我开始切身体验到它给课堂教学带来的革命。良好的开端是成功的一半。一节课是否能引起学生的学习兴趣,导入部分至关重要。生动有趣的导入可以使学生的注意力很快转移到课堂学 Mentioned in the past math class, students will think of “boring”, “boring”, “mechanical training” these words. Since information technology entered the classroom, I began to experience the revolution it has brought to classroom teaching. Well begun is half done. Whether a class can arouse students’ interest in learning, the import part is very important. A lively and intriguing introduction can quickly divert the student’s attention to classroom learning
