学生能正确地运用语言、文字、图表描述实验结果,是分析和解释实验现象、得出正确的实验结论的前提,也是学生应该具备的基本能力之一。因此,在生物实验教学中,我们必须加强对学生这种能力的培养。对实验中获得的信息资料,一般需要用分组归类、计算特征量和绘制图表等
Students can correctly use language, words, and graphs to describe the experimental results. This is a prerequisite for analyzing and interpreting experimental phenomena and obtaining correct experimental conclusions. It is also one of the basic abilities that students should possess. Therefore, in biological experiment teaching, we must strengthen the cultivation of this ability of students. For the information obtained in the experiment, it is generally necessary to use grouping, calculation of feature quantities, drawing of charts, etc.
