新的中学课程改革倡导以科学探究为主的自主合作式学习方式,强调发展学生的科学探究能力,培养学生的创新精神和实践能力。化学实验是进行科学探究的主要方式和途径,是化学教学中最常见最主要的探究活动。化学实验可以把观察、实验控制、收集事实、分析和统计结果等科学方法融于一体。让学生在感悟知识与过程和方法的相互作用中理解科学,理解化学。当学生学会怎样去学习,掌握正确的学习方法后,就会自觉地去探索问题、解决问题,这将让学生终身受益。 The new middle school curriculum reform advocates autonomous cooperative learning mode based on scientific inquiry, emphasizing the development of students ’ability of scientific inquiry and cultivating students’ innovative spirit and practical ability. Chemistry experiments are the main ways and means to carry out scientific inquiry, and are the most common and most important inquiry activities in chemistry teaching. Chemical experiments can combine scientific methods such as observation, experimental control, collection of facts, analysis and statistical results. Have students understand science and understand chemistry in understanding the interaction of knowledge and processes and methods. When students learn how to learn and master the correct learning methods, they will consciously explore and solve problems, which will benefit the students for life.
