1内容分析对于尺规作图,《义务教育数学课程标准》(2011年版)(以下简称《课标》(2011年版))要求:能够运用尺规作图完成基本作图;能用基本作图完成部分与三角形、圆有关的复杂作图;了解作图的道理等内容。涉及内容不多,但在实际教学过程中却是考查学生拼割图形、图案设计、建立数学模型进而解决实际问题能力的重要手段,是评价学生动手操作能力的重要指标,所以本课例进行适度挖掘,设计基本作图、复杂作
1 Content Analysis For the rules and regulations of compulsory education, the Standard of Compulsory Education Mathematics Curriculum (2011 Edition) (hereinafter referred to as “Curriculum Standard” (2011 Edition)) requires that the basic drawing can be completed by using the rule drawing; Completed part of the triangle, the circle of complex mapping; Understanding of the truth and other content. However, in the process of practical teaching, it is an important means to check the ability of students to cut patterns, design patterns and establish mathematical models to solve practical problems. It is an important indicator to evaluate students’ abilities of hands-on operation. Therefore, Mining, design basic drawing, complex for
