化学是以实验为基础的一门科学。化学实验能够帮助学生形成化学概念,理解和巩固化学知识,培养学生观察现象、分析问题和解决问题的能力,是培养学生实事求是、严肃认真的科学态度和科学方法的重要手段。因此,加强和改革化学实验教学对提高化学教学质量至关重要。传统的实验教学方法是教师做,学生看;教师讲,学生听;教师写,学生记,这既不利于培养学生的思维能力和智力开发,又不利于提高学生的独立思考和动手操作能力。现代教学理论认为:学生在一定条件下,完全可以通过自己的观察、实验、思考、分析、概括等方法,独立地发现问题、解决问题或得出结论,自己成为知识的再发现者。实验探究法就是这样一种行之有效的教学模式。这种方法就是学生在教师的指导下,教师与学 Chemistry is an experiment-based science. Chemistry experiments can help students form chemical concepts, understand and consolidate chemical knowledge, cultivate students' ability to observe phenomena, analyze problems and solve problems. It is an important means to train students to seek truth from facts, serious and serious scientific attitudes and scientific methods. Therefore, to strengthen and reform the chemistry experiment teaching is very important to improve the chemistry teaching quality. The traditional method of experimental teaching is done by teachers and students; teachers say that students listen; teachers write and students remember that it is not conducive to cultivating students 'thinking ability and intellectual development, but also not conducive to improving students' independent thinking and hands-on ability. According to modern teaching theory, under certain conditions, students can find problems independently, solve problems or conclude their own by discovering, experimenting, thinking, analyzing and summarizing. Experimental inquiry method is such an effective teaching mode. This method is the students under the guidance of teachers, teachers and learning
