化学中考考查计算知识的能力与方法在不断地创新,一题两解和自编题便是出现在中考试卷中的两种新题型。这些题目不是简单地考查同学们化学计算的基本功,而是更注重考查对化学知识的灵活应用及数据信息处理等能力。一、一题两解这类考题一般是给出相关的数据信息,要求同学们用两种不同的方法求解,引导同学们发散思维,在比较中训练一题多解、优化解题方法的能力。同学
In the field of chemistry, the ability and method of calculating knowledge are continuously innovating. The two questions and two solutions and the self-made questions are two new kinds of questions that appear in the middle school examination paper. Instead of simply examining students’ basic skills in chemical calculations, these topics focus more on examining the flexible application of chemical knowledge and data processing capabilities. First, a question and two exams These exam questions are generally given the relevant data and information, require students to use two different methods to solve, guide students to divergent thinking, training more than one problem in the comparison, the ability to optimize the problem-solving method .
