高中化学层次性习题设计策略探析

A Brief Analysis on the Design Strategy of Senior Chemistry Exercises

在新课改中明确指出高中化学习题需要能够有利于学生发现与提出问题,让学生能够亲自进行实验与调查,以便于学生能够有效应用已经掌握的知识,并由多方对问题进行思考与解决。不仅如此,新课改还要求教师能够结合实际教学要求来合理设计不同难度的习题,确保各个层次的学生需求都能得到满足,并且能够培养出各种类型素质的人才。为此下文在充分结合笔者对相关文献研究以及自己多年工作实际经验情况下,首先分析了高中化学进行层次性习题设计的原因,然后提出一些较为有效的策略,以供其他教师参考。

In the new curriculum reform,it is clearly pointed out that senior high school chemistry exercises need to be able to help students find and put forward problems,so that students can conduct experiments and investigations in person,so that students can effectively apply the knowledge they have mastered,and from many sides to think about and solve problems.Not only that,the new curriculum reform also requires teachers to be able to combine actual teaching requirements to reasonably design exercises of different difficulty levels,to ensure that the needs of students at all levels can be met,and to cultivate talents of various types of quality.For this reason,the following part,in full combination with the author’s relevant literature research and years of practical experience,first analyzes the reasons for the hierarchical exercise design in high school chemistry,and then proposes some effective strategies for other teachers’reference.
