生物学是一门实验性科学。对高中学生来说,生物实验教学主要包括常见的仪器、器具、药品的使用能力,还有对实验程序的理解能力,对实验结果的分析能力,对实验中出现的异常情况的处理能力等。一、让学生明确仪器的原理和药品的特性,是培养学生使用它们的能力的基础“知其然,应该知其所以然”。教师要善于把实验仪器及药品性质、使用原理讲清,这对 Biology is an experimental science. For high school students, biological experiment teaching mainly includes the common ability to use instruments, apparatus and drugs, the ability to understand experimental procedures, the ability to analyze experimental results, and the ability to deal with abnormal situations in experiments. First, to enable students to clear the principle of the instrument and the characteristics of medicines, is to develop students' ability to use them based on “know it, you should know why it is.” Teachers should be good at the nature of experimental equipment and medicines, use the principle of clarification, this right
