随着新课程改革的不断深入,近几年高考化学实验题更加突出对实验设计与探究能力的考查,还出现了一些将有机、无机、实验操作、化学反应原理等知识综合在一起的化工生产实验题。然而,该类试题往往得分率不高,令考生生畏。高三复习时惯用的做法是加大实验题训练的力度,但是复习的效果往往难尽如人意。笔者以为,实验复习观念的偏差是造成实验复习效果不佳的根本原因。下面以甲、乙两位教师对“测定1mol气体的体积”的复习过程为例说明。
With the continuous deepening of the reform of the new curriculum, in recent years, the Chemical Laboratory Experiment in the entrance exam has given more prominence to the ability of experimental design and inquiry, and some chemical production has emerged that combine organic, inorganic, experimental operation and chemical reaction theory together Experimental questions. However, such questions often score low, so that candidates fear. Senior high school review practice is to increase the intensity of experimental training, but the review of the results are often unsatisfactory. The author believes that the deviation of experimental review concept is the root cause of poor review results. The following to A, B two teachers on the “determination of 1mol gas volume ” review process as an example.
