《全日制义务教育物理课程标准》(以下简称《课标》)中明确指出,初中物理课程的构建要以科学探究为主线。这就要求我们在教学过程中要注重科学思维的培养,使学生经历基本的科学探究过程,学习科学探究方法,发展初步的科学探究能力,形成尊重事实,探索真理的科学态度。探究活动的阶梯性科学探究要善于把一个复杂的、难度较大的课题分解成若干个相互联系的小情景、小问题。不同的班级,学生的知识水平和能力也是不同的,因此在进行科学探 Full-time compulsory education physics curriculum standard “(hereinafter referred to as” standard ") clearly pointed out that the construction of junior high school physics curriculum should be based on scientific inquiry. This requires us to pay attention to the cultivation of scientific thinking in the process of teaching so that students can go through the basic process of scientific inquiry, learn scientific inquiry methods, develop preliminary scientific inquiry ability, and form a scientific attitude of respecting facts and exploring truth. The step-by-step scientific inquiry into inquiry activities should be good at breaking down a complicated and difficult subject into a few interdependent small scenes and minor problems. Different classes, the level of knowledge and ability of students are different, so in the scientific exploration
