近几年的生物高考中,实验设计题基本上都有所涉及,题目大都是要求学生根据已知条件,设计实验步骤,并对实验结果进行预测和分析,每次考试其所占分值还不少,因而在生物教学中,教师在平时教学中要注意加强学生在这方面的训练,帮助学生掌握实验设计的解题方法,提高解题能力。一实验设计题的一般解题过程1.确立思路设计实验,首先得有清晰的思路。要确立好思路,必须明确实验目的、熟悉实验原理。设计实验以实验目的为方向,明确本实验验证或探究的生物学现象;实验目的的完成理论依据是实验原理。 In recent years, the biological college entrance examination, the experimental design questions are basically involved, the subject mostly require students to learn the known conditions, the design of experimental steps, and the experimental results of the prediction and analysis of each test its share also Therefore, in the teaching of biology, teachers should pay attention to strengthening students’ training in this field during normal teaching, help students to master the experimental design of the problem-solving methods and improve the ability of solving problems. A general problem-solving process of experimental design process 1. Establish ideas Design experiments, we must first have a clear idea. To establish a good idea, we must clear the purpose of the experiment, familiar with the experimental principle. Design experiments to the purpose of the experiment for the direction of a clear test of this experiment or explore the biological phenomenon; the purpose of the experiment to complete the theoretical basis for the experimental principle.
