１.做学问之前首先学会做人2.知识文化修养和思想道德修养的关系三.追求更高的思想道德目标㈤ 说教学评价和反思：1.这节课主要是以学生为主体，老师为主导，让学生充分发表自己的看法，把理论的知识结合在实际的日常生活中，鼓励学生充分发表自己的意见，能调动学生学习的积极性，达到教学目的。这节课学生讨论，发言的机会很多，但由于我校的学生的基础薄弱，在发言时难免偏离老师引导的方向，甚至出现毫不相干的说法，由于本人经验不够此时如何去引导他们可能做的还不够好。2.新课程的教学，如何突破书本知识的局限，延伸更深层次的内容是一个难题。本节课在知识的处理上，把道德的重要性与道德的层次两个知识点补充了进去，目的是让学生在学习之前有一个情感的铺垫，从而更好地达到教学目标。

人教版高中历史必修3文艺复兴和宗教改革教案
三、宗教改革：1、背景：（1）文艺复兴的影响。文艺复兴中，人文主义学者尽管对宗教保持较为温和的态度，但其以人为中心的思想极大地冲击了天主教的精神独裁，天主教的权威日益受到人们的怀疑。（2）天主教会对欧洲尤其是德意志的压榨。中世纪的天主教会对人民进行严密的精神统治，基督教信仰的核心是“原罪”和“灵魂救赎”，即人生下来就有罪，只有信仰上帝，跟随耶稣才能得救。就“灵魂救赎”而言，最初强调的是个人信仰的作用，后来，神学家们又加上了种种繁杂的宗教礼仪，而且必须得到神职人员的帮助，灵魂才能得救。在经济上，天主教会还是最大的封建主，占有大量的土地，并征收什一税，对各国人民大肆搜刮。罗马教廷每年从德意志搜刮的财富达30万古尔登（货币单位），相当于“神圣罗马帝国”皇帝每年税收额的20倍。德意志也成了被教会榨取最严重的地区，素有“教皇的乳牛”之称。

（1）巨额的赔款，是列强对中国空前的大规模勒索；为支付这笔巨额赔款，清政府加紧搜刮人民，使人民生活更加贫困，社会经济更加凋敝。（2）在北京设立的“使馆界”，实际上是“国中之国”，是帝国主义策划侵略中国的大本营。外国侵略者控制京津地区，使清政府完全处于外国军队的控制之下，便于侵略者直接派兵镇压中国人民的反帝斗争。（3）按照条约规定，清朝官吏严厉镇压中国人民的反帝斗争，进一步成为帝国主义的帮凶。（4）改设外务部的规定，便于清政府能够按照外国侵略者的意旨实行卖国的外交政策。《辛丑条约》是帝国主义强加给中国的一个严重的不平等条约，列强除了穷凶极恶地对中国敲诈勒索外，还重新确立了以慈禧太后为首的清政府继续充当它们在华的代理人。
