以化学实验为基础是化学学科的重要特征之 一。化学实验对全面提高学生的科学素养有着极为 重要的作用。化学实验有助于启迪学生的科学思 维,训练学生的科学方法,培养学生的科学态度和 价值观。在教学中引导学生综合运用所学的化学知 识和技能,进行实验设计和实验操作,分析和解决 实际问题是新课程标准的目标和要求。我们通过以 下的例题及分析,演绎通过化学实验的设计,探究、 解决实际问题的过程。
Based on chemical experiments, it is one of the most important features of chemistry. Chemical experiments have an extremely important role in the overall improvement of students’ scientific literacy. Chemical experiments help inspire students’ scientific thinking, train students’ scientific methods, and cultivate students’ scientific attitudes and values. In teaching, students are guided to use the learned chemistry knowledge and skills comprehensively, carry out experimental design and experimental operations, and analyze and solve practical problems are the goals and requirements of the new curriculum standards. We use the following examples and analysis to deduce the process of exploring and solving practical problems through the design of chemical experiments.
