高考理科综合测试题中化学实验题的形式与难易一直是教师和学生最关注的 ,因为实验题赋分高且往往是学生最没有把握的题型 ,它的得分率的高低将直接影响化学的总体成绩。因此 ,我认为对近几年高考实验题 (已渐趋成熟 )的特点、潜在的导向作一些研究和总结 ,对促进教师教学观念 The form and difficulty of chemistry experiment questions in the science test of college entrance exams have always been of the highest concern of teachers and students, because the high scores of the test questions are often the most unsure questions of the students, and its score rate will directly affect the chemistry. The overall result. Therefore, I think that I have done some research and summary on the characteristics and potential guidance of the college entrance examination experiment in recent years.
