《课程标准(2011年版)》中明确指出:“化学实验是学生进行探究性学习的重要手段和途径,是进行科学探究的主要方式,它的功能是其他教学手段无法替代的.实验教学有利于启迪学生的科学思维,揭示化学现象的本质.”因此,我们在平时的教学中,要以实验为切入口,将化学实验贯穿化学教学的始终.充分利用化学实验,引导学生主动发现和提出问题,锻炼学生的自主探究能力;充分利用化学实验,发展学生的思维能力,优化学生的思维品质;充分利用化学实验,使学生乐学、善思,促 “Curriculum Standard (2011 Edition)” clearly states: “Chemical experiments are important means and ways for students to engage in inquiry learning and are the main ways to conduct scientific inquiry. Their functions are irreplaceable by other teaching methods. Which is conducive to inspiring students’ scientific thinking and revealing the essence of chemical phenomena. ”Therefore, in our usual teaching, we should take experiments as an entrance point and carry out chemical experiments throughout chemistry teaching .We should make full use of chemical experiments to guide students to actively discover and Put forward questions and train students’ self-exploration ability; make full use of chemical experiments to develop students’ thinking ability and optimize students’ thinking qualities; make full use of chemical experiments to make students learn, think and urge
