根据教育部有关文件规定,今年高考化学试题的范围不超出中学教学大纲和基本要求,试题内容的要求不超过中学所用统编教材所能达到的程度。在考核的知识范围缩小的情况下,如何使今年化学命题工作既符合高校选拔新生的要求,又有利于中学教学?我们的做法是:强调基础,注重应用,在基本要求所限定的知识范围内,多方面考查学生的能力。 一、考查运用基本理论的推理能力 根据基本要求,中学化学的一些基础理论,从知识水平来看,一般都是较为浅显的,如果只从正面考查知识内容,很难拉开考分的距离,这不利于高校选拔新生,也容易助长死记硬背的不良风气。例如,周期表和原子结构部分就是如此,在要求学生掌握的前18个元素中,很难 According to the relevant regulations of the Ministry of Education, the scope of the chemical examination questions for the college entrance examination this year does not exceed the syllabus and basic requirements of the middle school. The requirements for the content of the questions do not exceed the degree that the textbooks used by the secondary schools can achieve. With the narrowing of the scope of assessment, how can this year’s chemical proposition work not only meet the requirements of freshmen in college selection, but also be beneficial to middle school teaching? Our approach is to emphasize basic and application-oriented, within the scope of knowledge defined by basic requirements. It examines students’ abilities in many aspects. First, examine the use of basic theory of reasoning ability According to the basic requirements, some of the basic theory of middle school chemistry, from the perspective of knowledge, are generally relatively simple, if only from the front to examine the content of knowledge, it is difficult to open the distance between the test scores, It is not conducive to the selection of freshmen in colleges and universities, but it also tends to foster bad morale. For example, the periodic table and the atomic structure are such that it is difficult to ask students to grasp the first 18 elements.
