化学高考实验题过重地突出了能力的考查,而轻视了对实验基本操作的考查。实验题的考查内容主要侧重于实验装置的连接顺序,操作顺序,误差分析等方面的知识,尽管每年都重视这方面的训练,但失分率仍然较大,考生对实验题望而生畏,结果难题做不来,能得分的题又没时间做,这也是失分率较高的原因之一。一、找规律,走捷径对于基本实验操作的复习并不需要从头开始,而是可以采取归纳总结比较法,把简洁的办法教给学生,让他们从纷乱的头绪中找出规律,
Chemical college entrance exam questions overly highlight the ability test, and contempt for the test of the basic operation of the experiment. Examine the content of the experimental questions mainly focused on the experimental device connection sequence, operation sequence, error analysis and other aspects of knowledge, despite each year emphasis on training in this area, but the fractional rate is still large, the candidates fear of the experimental problems, the results difficult to do Do not come, can not score the title and time to do, this is one of the reasons for the higher score. First, find the law, take a shortcut For the review of the basic experimental operation does not need to start from scratch, but can be summed up to summarize the comparative method, the simple way to teach students to allow them to find out the law from the chaotic clues,
