化学是一门以实验为基础的学科,而实验的核心内容即是设计实验步骤,进行实验操作,并对实验现象进行描述与分析,进而推知结论。注重对实验细节的教学可以提高学生对实验的认知,并能引领学生更好地掌握知识的要点。以近三年的中考题来分析学生化学实验的掌握程度对中考答题的影响,进一步阐述注重初三实验细节教学的重要性。
Chemistry is an experiment-based discipline, and the core of the experiment is the design of experimental steps, the experimental operation, and the description and analysis of the experimental phenomena, and then infer the conclusion. Focus on the experimental details of teaching can improve students’ understanding of the experiment, and can lead students to better grasp the key points of knowledge. In the past three years, the senior high school entrance examination questions to analyze the degree of mastery of students’ chemistry experiment on the impact of the answer to the question, to further elaborate on the importance of teaching the third day of experiment details.
