实验设计是高考考查的重点。面对高考生物实验题,考生最棘手的问题是全程实验设计,即提供材料信息、药品、用具、实验原理等,要求设计实验思路,写出实验步骤,验证或预测实验结果。实验设计题书写也是考生最容易失分的地方,许多考生在答题过程中,心里知道答案,但在答题时因语言表达不规范而导致失分。在高考备考复习中,教师如何强化学生的实验设计能力、规范实验设计的答题语言而使他们减少失分呢?本文主要从剖析实验设计思路和规范答题语言两方面来分析实验设计题的解答问题。
Experimental design is the focus of the college entrance examination. In the face of college entrance examination biology experiment questions, the most difficult problem for candidates is the full experimental design, that is, to provide material information, medicines, utensils, experimental principles, etc., to design experimental ideas, write experimental steps, and verify or predict experimental results. The writing of experimental design questions is also the place where candidates are most likely to lose points. Many candidates know the answers in the process of answering questions, but in the answer questions, they lose their points because of non-standard language expression. In the college entrance exam preparation review, how can teachers strengthen the students’ experimental design ability and standardize the answer design language of the experimental design so that they can reduce the loss points? This article mainly analyzes the experimental design questions and the standard answer language to analyze the answer of the experimental design questions. .
