1问题提出逻辑思维是人们在认识过程中借助于概念、判断、推理等思维形式能动地反映客观现实的理性认识过程。对于数学而言,逻辑思维是指学生依据数学概念、命题做出判断以及运用判断进行推理、论证的思考过程。进入高中,数学内容以抽象内容为主,而高一是学生从形象思维过渡到抽象思维的重要阶段。学生的逻辑思维水平状况会直接影响数学学习。由于三角函数具有知识之间逻辑性和系统性强的特点,
1 PROBLEM PROBLEMS Logical thinking is a process of rational cognition that people can reflect the objective reality through thinking, judgment, reasoning and other forms of thinking in the process of cognition. For mathematics, logical thinking refers to the process of students’ thinking based on mathematical concepts, propositions to make judgments, and using reasoning to reason. Into high school, mathematics content to the abstract content-based, and the high one is the transition from the image of thinking students to an important stage of abstract thinking. The level of logical thinking of students will directly affect the mathematics learning. Because trigonometric functions have the characteristics of logical and systematic knowledge among knowledge,
