笛卡尔曾说过:“我所解决的每个问题都将成为一个范例,以用于解决其他问题。”例题教学作为数学课堂教学的主角之一,其重要性不言而喻。例题的示范与应用能使学生真正增长实战经验,是例题将知识与技能紧紧相连,是例题将思想与方法融会贯通,更是例题将学生的理论与实践和谐统一。对于内地新疆班的课堂,例题教学显得尤其重要。因为学生的汉语言能力十分有限,他们对概念的形成,公式的理解,往往需要比本地班的学生多付出一倍甚至几倍的努力。于是例题教学便成了学生理解概念、掌握公式的重要平台,重视例题 Descartes once said: “Every question I solve will serve as an example for solving other problems.” "The importance of the example teaching as one of the main characters in the classroom teaching of mathematics is self-evident. Demonstration and application of examples can enable students to really increase the actual combat experience, which is the example of the knowledge and skills are closely linked to the examples of ideas and methods will be integrated, but also an example of student theory and practice of harmonious unity. For the classes in the inland Xinjiang classes, the teaching of examples is of particular importance. Because students’ Chinese language ability is very limited, their understanding of the formation of the concept and the formula often requires twice or even more efforts than the local students. So the case teaching has become an important platform for students to understand the concept, master the formula, pay attention to examples
