人教版高中历史必修1甲午中日战争说课稿
3．甲午中日战争中国战败的原因 对于“中国战败的原因”这一难点的突破，主要通过设置问题“中国之败败在实力逊于日本吗？”通过幻灯片全方位分析其实中国的综合国力当时是强于日本的。并且在战前，日本毫无取胜的把握。让学生结合刚学习过的战争原因和经过进行讨论，从多方面分析中国战败的原因。经过讨论，学生可以得出以下结论：避战自保方针，没有积极备战，将领临阵脱逃，教师肯定并总结答案进行补充。中日对比：中国士兵出身农民，军事训练落后，散兵游勇；日本士兵出身武士，训练有素；中国将领大多临阵脱逃，并相互猜忌，受当时恶劣的官风影响；李鸿章深知北洋海军实情，缺乏军费，军备废弛。为政治资本奉行避战自保政策，慈禧太后挪用海军军费过寿，支持李鸿章。使中方处于被动的局面，一再贻误战机。而日本在天皇的带动下，全民备战，做了充分的战争准备。
