要培养学生的创新精神必须让学生自己学会学习、学会探究、形成终身学习的意识、动力和能力。从国内外的经验来看,＂探究性教学＂可以促进教师教学观念和教学行为的转变,使学生在参与探究中积极、主动的学习,并通过学习获得素质的全面发展。正因为如此,课堂中的探究性教学就显得十分重要了。而如何在课堂教学活动中设计好探究活动就是一个重大的课题。本文结合笔者多年来的教学实践就课堂＂探究性教学＂的实施,从有趣的教学情境,智力游戏,信息技术,构造＂陷阱＂,民主的气氛方面来设计探究活动,借以抛砖引玉。  相似文献

INTRODUCTION Fungi cause most plant diseases of all groups of microbes. During their infection cycles, fungal pathogens must undergo two key processes: first, penetration through cuticles into host plant cells; second, colonization in host cells utilizing nutrients from their hosts. To penetrate host cells, fungi de-velop a series of specialized infection structures such as appressorium, penetration peg, and infection hypha. The appressorium-mediated penetration is a process typical of s…  相似文献
