化学是一门以实验为基础的自然科学,科学的实验方法和良好的实验技能既是中学化学学习的关键,也是高考考核的热点、重点。近几年来,随着高考改革的不断深入,全国各省市的高考化学逐步加大了对化学实验的考查力度,题型推陈出新,考查角度多样,更加注重于素质和能力的考查。另一方面,从学生的答题情况来看,实验题是学生的主要失分点,学生在化学实验题中遇到的困难成为提高学生高考化学成绩的一大瓶颈。在高三备考中如何突破瓶颈?如何
Chemistry is an experiment-based natural science, scientific experimental methods and good experimental skills are not only the key to high school chemistry learning, but also hot and key points for college entrance examination. In recent years, with the deepening of college entrance examination reform, college entrance examination in various provinces and cities nationwide gradually stepped up the test of chemical experiments. Questions were introduced in a fresh and varied manner, with more focus on quality and ability tests. On the other hand, from the perspective of the students’ answers, the experimental questions are the main points of the students’ failure. Students’ difficulties encountered in the chemistry experiment become a big bottleneck in improving the academic performance of the college entrance examination. How to break the bottleneck in the senior high school entrance examination?
