生物学离不开实验,而实验往往是要通过推导和论证的,因此,学习生物学,就一定要研究生物实验,历年的高考更是注重对生物实验知识的考查,实验的考查试题已从了解实验原理、明确实验目的、掌握实验方法与步骤、分析实验现象、得出实验结果逐步过渡到让学生根据实验要求,自行设计实验方案,要求写出完整的实验步骤及实验注意事项,同时要求学生能够根据实验结果进行科学分析与预测。高考实验设计题,这类试题难度较大,在考试中学生的得分也很低,如何做好这类题呢?通过多年的教学经验,我认为要做好这类题目应注意以下几个方面:
Biology is inseparable from the experiment, and the experiment is often through the deduction and demonstration, therefore, to learn biology, it is necessary to study biological experiments, college entrance examination over the years is to pay more attention to the biological test knowledge test, test questions from the experiment Understand the principle of experiment, the purpose of a clear experiment, master the experimental methods and steps, analyze the experimental phenomena, and come to the gradual transition of the experimental results to enable students to design their own experimental program according to the experimental requirements, require writing complete experimental steps and experimental considerations, Students can conduct scientific analysis and prediction based on experimental results. College entrance examination experimental design questions, such a test more difficult, the test scores of students is also very low, how to do this kind of problem? Through years of teaching experience, I think we should do a good job of these topics should pay attention to the following aspects:
