随着新课程标准的颁布与实施,对高中化学习题提出更高的要求,要求教师设置的习题需有利于学生发现与提出问题,让他们以实验活动与调查为基础,灵活运用所学知识从不同角度分析与解决问题。教师可利用层次性习题来实现这一教学目标,帮助学生学习化学知识。笔者主要对高中化学层次性习题进行着重解析,然后制定部分科学的设计策略。 With the promulgation and implementation of the new curriculum standards, higher requirements for high school chemistry exercises are put forward. Teachers should be encouraged to find out and ask questions so that they can use the knowledge gained from experiments and surveys Analyze and solve problems from different perspectives. Teachers can use the hierarchical exercises to achieve this teaching goal, to help students learn chemical knowledge. The author mainly analyzes the high school chemistry gradation exercises and then formulates some scientific design strategies.
