密度是初中物理教学的一个重点,物质密度的测定也是初中物理的一个重要学生实验。因此,历年来有关物质密度测定的实验题也是各省市中考的热点。据不完全统计,仅2006年就有20多个省市的中考试题以不同方式考查了该问题,而此类题的考查尤以实验设计型为主,因为它既能体现新课改的精神,又能激发学生的探究兴趣。
Density is a key point in junior high school physics teaching. The determination of material density is also an important student experiment in junior high school physics. Therefore, the experimental questions related to the determination of the material density over the years are also hot topics in the provincial and municipal exams. According to incomplete statistics, in 2006 alone, there were more than 20 provinces and cities in the middle of the exam questions examined in different ways. The examination of such questions is mainly experimental design, because it can reflect the spirit of the new curriculum reform. , but also stimulate students’ interest in inquiry.
