丁肇中教授说过,自然科学不能离开实验的基础,特别是物理学,是从实验中产生的。我市初中自然科学实验操作抽查活动每年12月进行,已有五年。此项抽查活动与竞赛性质不同,是检查和促进实验教学的一个重要措施。抽查对象为初三年级学生,每校三名学生,抽查方法采用按各校自然科学(理、化、生)期中考试总平均来确定中等生,平均分加上和减去若干个标准差确定上等生和下等生,在三个等级中各抽一名学生应试。抽查名单仅提前半天通知学校,组织到县集中抽查,每名学生分别做物理、化学、生物实验各20分钟,由学科教研员、高中教师组成学科评分组对学生的操作逐项评分。本文仅分析物理实验操作中反映的问题,并谈谈对实验教学的若干启示。
Professor Ding Yizhong said that the natural sciences cannot leave the foundation of the experiment, especially the physics, which was generated from the experiment. The examination of natural science experimental operation in junior high school in our city is conducted every December, and it has been five years. This spot-checking activity is different from the nature of the competition and is an important measure for examining and promoting experimental teaching. The target students for the third grade students and three students in each school were selected for the middle school students according to the average of the middle school examinations for natural sciences (physics, chemistry, students) in each school. The average score was determined by adding and subtracting several standard deviations. For upper class students and lower class students, one student from each of the three grades should take the test. The spot check list is only notified half a day in advance and organized to collect counties in counties. Each student is to perform physical, chemical, and biological experiments for 20 minutes each. Subjects’ teachers and senior high school teachers form a subject scoring group to score each student’s operations item by item. This article only analyzes the problems reflected in the operation of physics experiments and talks about some inspirations for experimental teaching.
