进入高二,学生开始学习电、磁场以及光学和原子物理,有一很大台阶需要跨越。力学学习阶段,学生面对的小车、物块、小球等宏观物体是学生生活中常见的,学生对它们进行受力分析,会觉得比较自然。但一进入电场、磁场的学习,学生离开直观认识要去理解抽象的电场、磁场及分析微观带电粒子的受力,此时学生就有可能觉得茫然,无从着手,因为这部分知识常是生活中接触较少且又看不见、摸不着的,此时学生就会觉得难学,从而导致学生的差学进而厌学。 Into the sophomore, students begin to learn electricity, magnetic fields and optical and atomic physics, there is a big step need to cross. In the mechanics learning stage, the macroscopic objects such as the car, the block and the balllet that the students are faced with are common in the students’ life. It is more natural for the students to analyze them by force. However, as soon as they enter the electric field and learn the magnetic field, the students leave to intuitively understand the abstract electric field, the magnetic field and analyze the force of the microscopic charged particles. At this moment, students may feel dazed and unable to start because this part of knowledge is often in life Less contact and invisible, inadvertently, then the students will find it difficult to learn, leading to poor students learn and weariness.
