归纳总结、对比分析是化学学习中常用的科学方法。采用集合的形式将不同化学知识之间的联系或区别以图示的方式直观地反映出来,已成为中考化学考查的新趋势。这类试题题型新颖别致,把数学中集合的知识应用到化学中来,加大了学科间渗透的广度和深度,在一些综合性试题及开放型试题中得到充分体现。因这类试题能够考查答题人的阅图、析图能力及逻辑推理能力,故备受命题者的青睐。现以典型中考题为例汇总分析。
Inductive summarization and comparative analysis are commonly used scientific methods in chemistry learning. The use of sets in the form of visually reflecting the differences or differences between different chemical knowledge in a graphical manner has become a new trend in chemistry examinations in the middle school. These types of questions are novel and unique, applying the knowledge gathered in mathematics to chemistry, increasing the breadth and depth of inter-disciplinary infiltration, and being fully reflected in some comprehensive test questions and open-ended test questions. Because such questions can examine the examiner’s ability to read graphs, maps, and logical reasoning, they are highly favored by propositioners. Take the typical exam questions as an example to summarize and analyze.
