1现状分析去年,扬州市初中物理实验考察中安排了两个物理实验.一是用天平和量筒测量小石块的密度,二是用“伏安法”测量定值电阻的阻值.我正好在学校参加物理实验考察监考,在监考的全过程中,我目睹了学生的整个实验考察过程,发现学生在实验中确实存在一些问题,严重的表现在实验技能本领的缺失.1.1用天平和量筒测量小石块的密度,是八年级《物理》下

1 Situation Analysis Last year, two physical experiments were arranged in the investigation of physics experiment in junior middle school of Yangzhou City: one was to measure the density of small stones with balance and graduated cylinder; the other was to measure the resistance value of fixed resistance with “Voltammetry”. I happened to be attending physical examinations in the school. In the whole process of proctorning, I witnessed the students’ entire experimental investigation process and found that there were indeed some problems in the experiments of the students, which were seriously manifested in the lack of skills in experimental skills.1.1 With a balance And measuring the density of small stones, is the eighth grade “physics”
