Abstract In order to obtain excellent students with plant protection knowledge and creative and synthetic abilities,it is necessary to reduce single,confirmatory and demonstrative experiments,and enhance comprehensive,independently designed and practicing experiments. According to the characteristics and course of the university students in the second grade,some comprehensive and independently designed experiments were designed based on culture and observation of Bombyx mori,so as to train the students to master preliminary scientific methods.
Key words general entomology;comprenensive and independenty designed experiments;example design
普通昆虫学是最先向植保专业学生开设的专业基础课之一,其理论性和实践性均强,具有2个特点:一是研究对象复杂。昆虫种类繁多,占动物界中种类数的70%～80%;个体数量庞大,如沙漠蝗的单个种群个体数可高达250亿个;分布范围广,在自然界中几乎无处不在。二是研究内容广[1] [2] [3] [4] [5] [6] 下一页 |
