生物实验可以培养学生对常见的仪器、器具、药品的使用能力,还有对实验程序的理解能力,对实验现象的观察能力,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,是培养学生能力的基础教师要全面了解仪器的原理、药品的性能并熟练使用,否则实验中就会充满盲目性和危险性。如显微镜的使用,学生经常不能根据观察对象的特点和观察目的合理选择低倍镜和高倍镜,由于受好奇心的驱使和对低倍 Biological experiments can cultivate students’ ability to use common instruments, apparatus and drugs, as well as their ability to understand experimental procedures, their ability to observe experimental phenomena, their ability to analyze experimental results, their ability to handle abnormalities that occur during experiments Wait. First, to enable students to clear the principle of the instrument and the characteristics of medicines, is to train students’ ability to basic knowledge of the instructor to fully understand the principle of the drug’s performance and skilled use, otherwise the experiment will be full of blindness and danger. As the use of microscopes, students often can not reasonably choose low magnification and high magnification according to the characteristics of observation objects and observation purposes, due to curiosity and low magnification
