函数图象具有“直观、简便、准确”等其他数学手段所无法比拟的优点。正因如此,在每年高考物理试卷中,都会出现众多让人耳目一新的图象试题。为此,教师应高度重视物理图象的教学,要使学生不仅能正确识别、深入理解和全面掌握物理图象,而且能善于灵活利用图象处理各种疑难问题。笔者认为教师对物理图象的教学应当关注以下四个方面。一、使学生明确物理图象的多重内涵
The function image has the advantages of “intuitive, easy and accurate” and other mathematical methods. Because of this, in the annual college entrance examination physical examination, there will be many refreshing image test questions. To this end, teachers should attach great importance to the teaching of physical images, to enable students not only correctly identify, in-depth understanding and comprehensive control of physical images, but also be good at flexible use of image processing various difficult problems. I believe that teachers should pay attention to the following four aspects of the teaching of physical images. First, to enable students to clear the multiple images of physical content
