高考化学实验题对中学化学实验教学的检测既有有效性,又有局限性,其局限性 在这里暂不讨论.其有效性是因为有这样一些试题(以下称为A类)能够把“平时做 实验与平时不做实验”的考生较好地区分开来;另一类试题(以下称为B类)则是那 些通过“听实验、画实验而不做实验”的考生也能得高分的.广大化学教师所称道的高 考试题也正是A类试题,再从各地历年高考之后对考生的答题情况分析来看,结果 也表明:考生对化学实验题的失分率最高的恰恰也是A类试题.这一情况应该引起 我们高度重视:一是说明中学化学实验教学仍然是薄弱环节;二是A类试题理应成 为高考命题的热点问题.
The examination of chemistry test in college entrance examination has both validity and limitation in the chemistry experiment teaching in middle schools. Its limitations are not discussed here. Its effectiveness is because there are some questions (hereinafter referred to as “A”) that can be used to Usually, the test is usually better separated from the test that is usually done without experiment; the other test questions (hereinafter referred to as B) are those who can pass “listen to experiment and draw experiment without experiment”. High scores. The majority of chemistry teachers said that the high exam questions are also A-type questions, and then from the analysis of the candidates after the calendar year after the college entrance examination, the results also show that: the examinees on the chemical experiment questions, the highest rate of loss It is also a Class A test question. This situation should cause us to attach great importance to: First, explain the chemistry experiment teaching in middle school is still a weak link; second, the A class test question should be a hot issue of the college entrance examination proposition.
