与2013年北京物理高考实验题相似,2014年的实验题仍然考查了电学实验部分.该题以“测定干电池的电动势和内阻”为实验目的,将电路选择、仪器选取、数据分析和函数图像关系融合为一道考题,突出考查学生对物理实验中的实验操作的理解.此考题出题灵活、富有新意、综合性强,突出了对学生物理思想以及综合能力的考查,具有一定的区分度.本文对该题的最后一问的图像关系的确定进行分析,指出学生的易错点及3种不同思考方法,希望
Similar to the 2013 Beijing Physics Entrance Examination, the experimental questions in 2014 still test the electrical experiment part. The purpose of the experiment is to test the electromotive force and internal resistance of the dry battery. The circuit selection, equipment selection, data analysis and Function and image fusion as a test question, highlighting the students to understand the experimental operation of the physical experiment.This test questions flexible, innovative, comprehensive, highlighting the student’s physical thinking and comprehensive ability test, with a certain distinction Degree.This paper analyzes the determination of the image relationship of the last question of the question, pointing out that the students are easy to be wrong and three different ways of thinking, hope
