生物学是一门实践性很强的学科。我们结合教学,理论联系实际,将生物学知识运用于社会生产实践,为振兴当地经济建设服务。1985年以来,我们开设了多个生物课外活动兴趣小组,进行了多项科学试验,并取得了一定成果。初中一年级的学生,年龄比较小,根据他们好动手的特点,我们在讲“种子”这一章时,进行了怎样贮藏种子与粮食、测定种子发芽率的实习,要求全班每个学生在家里做。实习前讲清长期保存种子与粮食的最佳人工条件是干燥、低温、通风、发芽率要在90%以上,种子方能作播种用,这些是关键性的知 Biology is a highly practical discipline. We combine teaching, theory with practice, biological knowledge applied to social production practices, to revitalize the local economic construction services. Since 1985, we have set up a number of biological interest groups for extra-curricular activities, conducted a number of scientific experiments, and achieved some results. According to the characteristics of their good hands, when we talk about “Seeds”, we conducted internships in how to store seeds and grain and determine the germination rate of seeds. We asked each student in the class Home to do. Prior to internship to clarify the long-term preservation of seeds and food is the best artificial conditions of dry, cold, ventilated, germination rate should be above 90%, the seeds can be used for sowing, these are the key to know
