化学实验在化学教学中具有非常重要的作用,学生在实验中能经受思维能力、分析能力和观察能力的锻炼。学生的学习情绪、意志、毅力等品质的形成,也能通过实验来实现。以往的化学实验,基本上是验证型实验,实验目标、仪器药品及操作方法,甚至实验现象,课本上均描述得很清楚,学生只要按其所述动手即可。高中化学新课程以提高学生的科学素养为宗旨,着眼于学生未来的发展,把转变学生的学习方式,帮助学生形成终身学习的意识和能力作为重要理念,创设出许多探究型化学实验,这对中学化学教学改革提出了全新的要求。探究型化学实验,是在一定情境下,学生通过各种实验活动,包括分类、交流、观察、测量、推断等活 Chemistry experiments play a very important role in chemistry teaching, and students are able to withstand the training of thinking ability, analyzing ability and observation ability in experiments. Students learn the formation of emotions, wills, perseverance and other qualities, but also through experiments to achieve. In the past, chemical experiments were basically proving experiments, experimental targets, instruments and operating methods, and even experimental phenomena. All the textbooks were clearly described, and students should follow the stated procedures. High school chemistry courses to improve the scientific literacy for the purpose of students, focusing on the future development of students, to change the way students learn to help students form lifelong learning awareness and ability as an important concept, to create a number of inquiry-based chemical experiments, which pairs High school chemistry teaching reform put forward new requirements. Inquiring-type chemistry experiments, under certain circumstances, students through various experimental activities, including classification, communication, observation, measurement, inference and other activities
