化学是一门以实验为基础的自然科学,化学实验是化学学科的基础和灵魂。近年来中考中对学生完成实验问题的能力要求有所提高。综合性实验题信息量大,渗透性强,比较好地考查了学生综合运用知识分析解决问题的能力,这就要求教师在实验教学中应注重对学生进行完成实验问题的能力的培养。完成实验问题必须注意“三性”:必须遵循科学性,了解 Chemistry is a natural science based on experiments. Chemical experiments are the foundation and soul of chemistry. In recent years, the ability of students to complete experimental problems has increased in the examinations. The comprehensive experimental items have a large amount of information and strong permeability, and they have examined the students’ ability to comprehensively use knowledge analysis to solve problems. This requires teachers to focus on cultivating students’ ability to complete experimental problems in experimental teaching. When completing the experiment, we must pay attention to the “three characteristics”: we must follow the scientific nature and understand
