数学新课程标准告诉我们,教师要充分关注学生的学习过程,遵循学生的认知规律,合理组织教学内容,建立科学的训练方法.使学生不仅获得数学知识、基本技能,更要获得数学思想和观念,形成良好的数学思维品质.每年的中考,函数题都是重中之重,题型千变万化.教师在函数教学中,通过对题目合理的转译与演变,能充分培养学生图像理解能力、数学建模能力和数学思维能力.1.题目呈现.
The new mathematics curriculum standard tells us that teachers should pay full attention to the students ’learning process, follow the students’ cognitive rules, organize the teaching content rationally, and establish a scientific training method so that students not only acquire math knowledge and basic skills but also acquire mathematical ideas and Concept, to form a good mathematical thinking quality.Every year in the test, the function of the question is the top priority, the subject ever-changing.Teacher in the function of teaching, through the translation and evolution of the subject reasonable to fully develop students’ ability to understand the image, mathematics Modeling ability and mathematical thinking ability.
