人教版高中历史必修1辛亥革命教案2篇
①从政府人员组成看，南京政府是一个以资产阶级革命派为主体的政府。②从政府颁发的法令和措施看，这些法令体现了资产阶级民主革命的要求，对于发展民族资本主义经济、资产阶级民主政治和文化教育以及改革社会风气，都起了积极作用。③从颁布的《中华民国临时约法》看，宪法体现了三权分立的政治体制，体现了资产阶级民主主义的要求，是中国历史上第一部资产阶级民主宪法，具有反封建专制制度的进步意义。（2）从南京临时政府的内外政策分析南京政府的根本弱点①未彻底地反封建。它没有采取比较彻底的反对封建主义的措施，特别是对封建统治的基础——地主阶级土地所有制没有触动，这样，南京临时政府也就不能真正地把广大人民群众动员起来，因而缺乏真正的群众基础。

【课后研讨】当互联网正大踏步走进人类生活的时候，人们对网络作用的认识似乎还是模糊不清。一种意见认为，作为中学生，他们上网的机会很多,互联网向他们展示了各类知识结构,网络为他们提供了大量信息，又给他们提供了一个接触社会的个性化和国际化的空间，给了他们一个展示自身能力的大舞台,所以他们对于知识选择的灵活性大大增加，学习的主动性也大大提高，学习的内容自然大大超出了狭隘的课本范围，这对于学生能力的提高应是大有裨益的。另一种意见认为，网络的出现无疑为推进素质教育提供了一块绿洲.但部分中学生上网更多的是为了消遣和娱乐，因为网络--这个完全虚拟的世界是他们放松自己的最佳场所。同时也许正基于这一点，家长和师长才会对中学生上网出现不同程度的抵制，因为他们认为网上娱乐分散了他们过多的精力，会对学业造成影响；更为重要的是，他们害怕网络上的不良信息对他们的身心不利。
