生物学是一门以实验为基础的自然科学,实验与探究能力是高考要求的四项能力要求之一,有关实验探究的试题在高考试卷中所占的比例一直很大.高中生物实验要求学生要动手操作、动脑分析,掌握相关实验的原理、方法步骤、解释实验现象、分析实验结果、得出正确结论等内容.实验误差是做实验时经常面对的问题,实验误差有方法误差、仪器误差、人员误差、环境误差等,尽量避免或均衡实验误差,才能获得准确的实验结果,对实验误差进行分析也往往作为生物考试命题的内容.以
Biology is an experiment-based natural science, the ability of experiment and inquiry is one of the four competency requirements of the college entrance examination, the proportion of test questions in the college entrance examination papers has always been a high proportion of high school biology experiments require students To hands-on operation, dynamic brain analysis, master the relevant experimental principles, method steps, explain the experimental phenomena, analyze the experimental results, draw the correct conclusions, etc. Experimental error is often encountered in the experiment, the experimental error method error, Error, personnel error, environmental error, try to avoid or balance the experimental error in order to obtain accurate experimental results, the analysis of experimental error is often used as the contents of the biological examination proposition.
