纵览近40年的高考物理试题发现,带电粒子在电磁场中的运动一直是考查重点,而以回旋加速器为试题情景更是高频发生.本文以2009、2011、2016高考物理江苏卷中三道回旋加速器计算题为例,赏析其在能力立意下传统模型的创新和物理原汁原味的体现,在此基础上探讨进一步提高高中物理教学与复习质量的建议.
An examination of the physical exam questions in the college entrance examination in the past 40 years found that the motion of charged particles in the electromagnetic field has always been the focus of examinations, while the scenario with cyclotron accelerators is occurring at high frequencies. This article takes the three rounds of swings in the physical examination of Jiangsu in the 2009, 2011 and 2016 college entrance examinations. Accelerator calculation example as an example, appreciation of the traditional model of innovation in its ability and concept of physical authenticity, and on this basis to explore ways to further improve the quality of physics teaching and review recommendations.
