一、计算机多媒体网络辅助教学突出了生物教学的直观性,并且能使微观世界宏观化直观性原则是教学中一个重要原则。利用现代化教学手段能够真实、生动、形象地展示生物的各种生理活动,显示生物的宏观世界和微观世界,把抽象的内容形象化,如讲葫芦藓的生殖特点。葫芦藓个体小,生殖过程必须借助于水的条件才能完成。采用现代化的教学手段,显示器上首先出现葫芦藓的完整植株,再把各个部分用分解的形式描述:其蒴帽和蒴盖脱落后,由孢蒴中放散出大量的孢子,孢子萌发形成原丝体、长出假根和芽体,由芽发育成葫芦藓植株(配子体)。配子体中的精子 First, computer multimedia network assisted teaching highlights the intuitive teaching of biology, and can make the microscopic world of macro-intuitive principle is an important principle in teaching. The use of modern teaching methods can be true, vivid, vivid display of various biological biological activities, showing the biological macroscopical and micro-world, the abstract content visualization, such as gourd moss reproductive characteristics. Gourd moss individual small reproductive process must be based on the conditions of water to complete. The use of modern teaching methods, the monitor first appeared gourd mulberry complete plant, and then all the parts in the form of decomposition: the capsule cap and capsule cover off, spore from the spore release a large number of spores, spores germination to form the original silk Body, grow fake roots and buds, buds developed into gourd plant (gametophyte). Sperm in the gametophyte
