国内外关于教育教学的文献概括,主要是涉及你所写的方面的文献,他们的主要观点,发表时间,文章题目,(比如,<<文章题目>>（张三，2003）提出了那些观点，做了什么分析），进而引出你所做的研究与他们有什么不同,对他们的观点有哪些改进,比如,可能他们并没有进行量化研究(举个例子而已),这样既显得你为了写这篇文章阅读了大量资料,做到了知己知彼,又体现了你文章的过人之处最好参照你要投稿的杂志的格式，符合他们的要求。
文献综述是对论文选题研究现状的梳理，但并不仅仅是把文献进行简单的堆砌与罗列，而是需要在总结梳理别人研究的同时，对已有的研究做出评价，也就是说有述有评，这也是为什么文献综述也叫做文献述评的原因。
对于所查阅的文献建议以相应研究方向的参考书目为好，对于书写格式可以参考网上的综述。至于正文，给你一个参考写法吧，先把你构思好的提纲按主标题和分标题列好，然后再在各个标题下填充相关内容，这样显得逻辑清晰，写的时候也方便。综述还是比较好写的，一般都以写其理论及实践应用的进展为主~。。加油写吧
记得我刚入学写第一篇综述的时候连什么是综述都不清楚，so先跟你介绍一下。文献综述，是指就某一时间内，作者针对某一专题，对大量原始研究论文中的数据、资料和主要观点进行归纳整理、分析提炼而写成的论文。综述属三次文献，专题性强，涉及范围较小，具有一定的深度和时间性，能反映出这一专题的历史背景、研究现状和发展趋势，具有较高的情报学价值。所以写综述的基本步骤包括：选择主题、文献搜索、展开论证、文献研究、文献批评和综述撰写具体就是：1、先要确定你想写什么方面的，也就是主题2、检索和阅读文献，这也是撰写综述的重要前提工作，一定要对所属领域多了解，知道大概的研究趋势和方向及研究成果3、开始撰写综述，其实我个人觉得你可以边看文献边开始攥写，因为是第一次写所以速度不会很快，读了一部分后就可以开始写了，后面觉得不满意可以再改嘛文献综述的格式相对多样，但总的来说，一般都包含以下四部分：即前言、主题、总结和参考文献。撰写文献综述时可按这四部分拟写提纲，再根据提纲进行撰写工作。插入参考文献时建议你用endnote软件，以后再写就更方便了，我有安装包哦

这当然还得继续查找资料的。也就是说论文也不是着急必须马上完成的。如果需要哪方面的资料，那也要全方面的去寻找。如果你缺少这方面的资料那你的作文可能就会不完美。所以说还是努力去寻找比较好。
当然不能随便编页码，你必须查询好了标到参考文献的最后。
