所谓思维品质是指个体思维活动特殊性的外部表现。从理论上讲包括思维的严谨性、思维的灵活性、思维的深刻性、思维的批判性和思维的敏捷性等品质。而函数作为高中数学的主线,贯穿于整个高中数学的始终。函数的定义域是构成函数的两大要素之一,函数的定义域似乎是非常简单的,然而在解决问题中不加以注意,常常会使人误入歧途。在解函数题中强调定义域对解题结论的作用与影响,对提高学生的数学思维品质是十分有益的。
The so-called thinking quality refers to the individual externalities of the particularity of thinking activities. In theory, including the rigor of thinking, flexibility of thinking, profound thinking, critical thinking and thinking of the agility and other qualities. The function of high school mathematics as the main line, throughout the high school mathematics has always been. The domain of a function is one of the two elements that make up a function. The domain of a function seems to be very simple. However, paying attention to the problem is often misleading. It is very beneficial to improve students’ thinking quality of mathematics by emphasizing the role and influence of domain definition in solving function problems.
