化学是一门以实验为基础的自然科学。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。因此国内外课程改革中都有一个共同趋势:走向实验。中学实验以验证性实验为主,验证性实验强调演示和证明,注重实验结果;虽有利于培养学生的实验操作、数据处理和计算能力却使他们探究物质世界的本能受到抑制。而探究性实验,能使学生真正成为
Chemistry is a natural science based on experimentation. Experimental teaching is conducive to inspiring students’ scientific thinking and revealing the nature of chemical phenomena. Therefore, there is a common trend in curriculum reform both at home and abroad: to experiment. The middle school experiment was based on confirmatory experiments, the confirmatory experiments emphasized demonstrations and proofs, and focused on the experimental results. Although it was beneficial to develop students’ experimental operations, data processing, and computational capabilities, their instincts to explore the material world were inhibited. And exploratory experiments can make students really become
