在新课标试卷中,物理计算题分为一力一电两题,共计32分,从2016年全国卷Ⅰ的两道计算题来看,第24题考查电磁感应现象中的双金属棒问题,实考难度为0.507,区分度为0.72,这是一道比较基础的试题。25题为斜面上的多过程问题,实考难度为0.220,区分度为0.71,难度较大。近几年高考也是如此,两道计算题的难度虽有波动,但就两题而言,难度相差较大,区分度高。在高考复习中,同学们要针对计算题常见问题以及解题方法进行突破,提高复习的效果。
In the new curricular examination papers, the physical calculation is divided into one power and two power problems, a total of 32 points, from the 2016 National Volume I calculation of the two questions, the first 24 questions examines the electromagnetic induction phenomenon bimetallic stick problem , The actual test difficulty is 0.507, the discrimination is 0.72, which is a more basic test questions. 25 entitled multi-process problems on the slope, the actual test difficulty of 0.220, the discrimination is 0.71, more difficult. In recent years, the same is true of the college entrance examination, although the difficulty of two calculation problems fluctuate, but the two questions, the difficulty of a larger difference between the high degree of differentiation. In the college entrance examination review, students should make a breakthrough for the calculation of common problems and problem solving methods to improve the review results.
