在初中化学教学中,需要对学生加以培养的能力是多方面的,其中实验能力、观察能力和思维能力的培养显得更为重要。因为,实验是学生认识物质的性质和变化规律的依据,观察(重点是对实验的观察)是学生获得感性材料的基本方法,而思维则是使这些感性材料抽象概括为概念和理论知识的唯一途径。因此,对初中学 In junior high school chemistry teaching, students need to be cultivated in many aspects, including experimental ability, observation ability and thinking ability training is even more important. Because experiment is the basis for students to understand the nature and variation of matter, observation (focusing on the observation of experiment) is the basic method for students to acquire perceptual material, and thinking is the only way to abstract these perceptual materials into abstract and theoretical knowledge way. So for junior high school
