在初中物理教学中进行学法指导,教材是载体,教师是关键.教材中蕴藏有丰富的学法指导功能,一旦被挖掘出来,就会释放出巨大的能量.本文以“密度”的教学为例,谈谈在初中物理教学中如何利用教材对学生进行学法指导,培养认知能力.一、课题导入,对学生进行实践学习法指导,培养实践认知能力.课题的导入,可先让学生自己动手.用天平称出体积相同的铁块、铝块、木块的质量.然后,

In the physics teaching of junior middle school, the instruction of learning method is carried out. The teaching material is the carrier and the teacher is the key. The teaching material has rich instructional guidance function. Once it is excavated, it will release a huge amount of energy. This paper uses “density” Teaching as an example, talk about how to use textbooks in junior high school physics teaching for students to learn methodological guidance, to cultivate cognitive skills. First, the introduction of the subject, the practice of student learning guidance, training of practical cognitive ability. Introduction of the subject, can be Let students start with their own hands. Use scales to weigh the same mass of iron, aluminum, and wood. Then,
