1问题的提出苏科版初中物理教科书强化了学生对图像方法的学习,第一章《声现象》通过仪器观察不用乐器发声的波形,首次给学生图像的感性认识;第二章《物态变化》第一节就通过对80℃热水每隔2min水温的测量,介绍从具体温度测量值到图像的转化过程,使学生认识到图像可以直观描述物理过程,体现物理变化规律,它是分析和解决物理问题常用的一种重要方法.随后在观察水的沸腾、探究冰和烛蜡熔化的实验
1 PROBLEM SUBMISSIONS Suke Edition junior high school physics textbook reinforces students ’learning of image methods. The first chapter of “Sound Phenomenon” observes the waveform without instrument sound for the first time and gives the perception of students’ images for the first time. The second chapter “ ”The first section through the 80 ℃ hot water every 2min water temperature measurements, from the specific temperature measurement to image conversion process, so that students realize that the image can be intuitive description of the physical process, reflecting the laws of physical change, which is the analysis and An important way to solve physical problems is to experiment with the observation of the boiling of water and the melting of ice and candle wax
