“对话教学”的核心是对话。它是指师生基于相互尊重、信任和平等的立场,通过言谈和倾听而进行双向沟通、共同学习的方式。《数学课程标准》明确指出:动手实践、自主探索、合作交流是学习数学的重要方式。对话教学正是合作交流的主要手段。“沟通和合作是对话教学的生态条件”。在教与学双方的沟通与合作中,对话的精神才得以体现。如何在数学课堂中有效地实施对话教学?本人就以《统计》一课的教学谈谈对话教学的体会。一、精心预设教学情境,激发学生的对话欲望和谐的师生关系是师生进行对话的前提。只有精心预设教学情境,有效构建和谐的师生关系,学生才能愿意同老师对话、乐于同老师对话,才能将自己的所思所想主动表达出来,与老师进行交流。教学《统计》这一课的开始,师出示课件,创设小猪乐乐过生日的情境,激发学生参与活动的兴趣: “Dialogue teaching ” is the core of dialogue. It refers to the teachers and students based on mutual respect, trust and equality, through dialogue and listening to two-way communication, learning together. “Mathematical Curriculum Standards” clearly pointed out: hands-on practice, independent exploration, cooperation and exchange is an important way to learn mathematics. Dialogue teaching is the main means of cooperation and exchange. “Communication and cooperation are the ecological conditions of dialogue teaching ”. In the communication and cooperation between teaching and learning, the spirit of dialogue can be reflected. How to effectively carry out dialogue teaching in math class? I will talk about the teaching of dialogue with the teaching of “statistics”. First, carefully pre-teaching situation, stimulate students desire for dialogue and harmonious relationship between teachers and students is the premise of dialogue. Only by carefully presetting the teaching situation and effectively constructing a harmonious relationship between teachers and students, students are willing to talk with the teacher and are willing to talk with the teacher so that they can express their thoughts and communicate with the teachers proactively. At the beginning of teaching “Statistics”, teachers show their courseware, set up the situation of piggy lex birthday, and arouse students’ interest in participating in activities:
