化学是一门以实验为基础的自然科学,化学实验在化学教学中发挥着无可替代的作用。新的化学课程标准强调:“通过以化学实验为主的多种教学活动,使学生体验科学研究的过程,激发学生学习化学的兴趣,强化科学探究的意识,促进学习方式的转变,培养学生的创新精神和实践能力。”一、开展探究性实验教学的意义实验是一种探究性活动,积极开展以实验为基础的教学活动,实施探究的化学实验教学,具有重要意义。它不仅能够为学生充分发挥实验能动性提供重要途径,而且还是有效实施中学化学实验教学目的,落实培养科学素质目标的重要且必要的前提条件。探究性化学实验教学,是同注入式的化学 Chemistry is an experiment-based natural science, chemical experiments play an irreplaceable role in chemistry teaching. The new chemistry curriculum standard emphasizes: “To enable students to experience scientific research through a variety of teaching activities based on chemical experiments, to stimulate students’ interest in learning chemistry, to enhance the awareness of scientific inquiry, to promote the transformation of learning styles, and to train students Innovation and practical ability. ”First, to carry out the significance of experimental teaching of inquiry is an inquiry activity, and actively carry out experimental teaching activities based on the implementation of inquiry chemistry experiment teaching, of great significance. It can not only provide an important way for students to give full play to the experimental initiative, but also effectively implement the purpose of chemistry experiment teaching in middle schools and implement the important and necessary preconditions for training scientific quality objectives. Inquiry chemistry experiment teaching, is the same with injection chemistry
