化学是一门实验科学,化学的起源与发展均得益于科学实验。教材中设置了大量的实验供学生完成,目的是提升学生的实验能力。与此同时,实验综合题通常被视为考查学生实验能力的重要手段。本文通过分析实验教学与科学发现过程以及实验综合题考查过程的融合,发现实验教学中存在的问题与缺陷,提出相应的教学建议,为中学化学教学提供参考。一、学生实验能力发展情况分析1.该校学生实验综合题得分率分析高考(模拟)化学试题的大题基本包括四个部分:有机综合、
Chemistry is an experimental science, the origin and development of chemistry are benefited from scientific experiments. The teaching materials set a large number of experiments for students to complete, the purpose is to enhance the experimental ability of students. In the meantime, experimentally integrated questions are often considered as an important means of examining students’ ability to experiment. By analyzing the process of experimental teaching and scientific discovery and the integration of experimental comprehensive examination, this article finds the problems and defects in experimental teaching and puts forward corresponding teaching suggestions to provide reference for chemistry teaching in middle school. First, the analysis of the development of students ’experimental abilities 1. The school students’ comprehensive experimental questions score analysis The main topic of the college entrance examination (simulated) chemical tests basically includes four parts: organic synthesis,
