高考化学命题指向明确:具有较高的信度、效度,必要的区分度和适当的难度,有利于高校对人才的选拔,全面检测考生的化学科学素养。连续反应由于存在的广泛性及其本身蕴含学科素养的丰富性被普遍用于对学生学科素养的考查。本研究在对连续反应进行界定的基础上,对常见连续反应进行举例,尝试在归纳基础上研究连续反应发生的一般条件,然后结合北京高考对连续反应在考试中的应用进行分析,最后对连续反应在教学中如何开展这一问题进行简单探讨。
College entrance chemistry proposition point clear: with high reliability, validity, the necessary degree of differentiation and the appropriate degree of difficulty is conducive to the selection of qualified personnel in colleges and universities, a comprehensive test of candidates chemical and scientific literacy. Continuous response due to the existence of extensive and its inherent richness of academic quality is widely used for the examination of the academic quality of students. Based on the definition of continuous reaction, this study gives an example of common continuous reaction, attempts to study the general conditions of continuous reaction on the basis of induction, and then analyzes the application of continuous reaction in the examination in combination with Beijing college entrance examination. Finally, Response to teaching how to carry out this issue for a simple discussion.
