思维是一个多侧面、多形态、多水平、多联系的多维结构,它包括思维的目的、过程、材料、品质、环境和监控.其中,思维品质是区分一个人思维乃至智力层次、水平高低的指标,因而成为学生发展其智力与能力的突破口.函数是贯穿于整个高中数学的一根主线.函数的定义域是构成函数的要素之一,在解决问题中不加注意,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
Thinking is a multi-dimensional, multi-modal, multi-level and multi-dimensional structure that includes the purpose, process, material, quality, environment and monitoring of thinking, in which the quality of thinking is to distinguish one mind and even intellectual level Indicators, and thus become a breakthrough point for students to develop their intelligence and ability.Function is a main line throughout the mathematics in high school.Function definition domain is one of the elements that constitute a function, in the solution of the problem without attention, often make people mistake Lost and Found in the function of the problem stressed the domain of the problem solving effect and impact on improving the quality of students’ mathematical thinking is
