评论式笔记不单是摘录，而且要把自己对读物内容的主要观点、材料的看法写出来。其中还可表达出笔记作者的感情。评论式笔记有下列几种：
1．书头批注
书头批注是一种最简易的笔记作法。就是在读书时，把书中重要的地方或自己最深的地方，用笔在字句旁边的空白处打上个符号，或者在空白处加批注。如毛泽东在读<伦理学原理>一书时，用朱墨两种色笔在书中作了不少的圈圈点点，遇到他认为观点正确、文字优美的地方，就批上“此论颇精”、“此言甚合我意"，认为不对的地方就画‘‘×”，或批上“不通¨、“荒谬”之类词句。
这种笔记方法只能在自己的书上用，这是应当注意的。
2．评注
评注笔记，是读完读物后对它的得失加以评论，或对疑难之点加以注解。例如顾维桢(捕风提影说思维>中的一段文字：哥德尔的不完整定理。是数学史里的一个里程碑。原来在严谨的.数学堡垒之中，竞有一大漏洞，而且这漏洞是无可填的。本来严谨的数学架构，以少数的公理为基础，以明确的推演为方法，导出七层宝塔似备辉煌威果来，真是美不胜收。而且高妙的数学架构，严谨之外，兼具普及性：貌似不同的事物，透过抽象表达，往往可以归纳在同一种数学描述范围之内，看来真是放诸四海而皆；隹了。哥德尔却证明，凡是普及性高的正式逻辑系统，其中必有某些命题，是无法以这系统的逻辑去辨别其是非的。这毛病多半出在“只缘身在此山中”。

摘录式是阅读活动中收集资料日寸最常用的记录形式。主要是为了以后开展科研活动时用。它要求准确无误地摘录原文的语句段落，还要注明出处，便于引用和核实。摘录式笔记可分为：
1．索引
索引笔记只记录文章的题目、出处。如书刊篇目名、编著者、出版年月日。如果是书，要记册、章、节，出版社名称，出版年月及版次；如果是期刊，要记期号，报纸要记年月日和版面．以备查找方便。例如：钱仓水、郝树明主编：《教师职业技能全书．文科卷》，中国人民大学出版社，1992年9月第l版。孙晓远：(对容易混淆的数学概念的分析，<中学生数学报1990午6月7日第2版。
2．摘抄原文
摘抄原文就是照抄书刊文献中与自己学习、研究有关的精彩语句、段落，作为日后引用的原始材料。摘抄原文要按照原文的内容自己标上一个分类的题目，便于资料的归类和日后采用，在引文后面要注明出处。例如：中学物理实验教学
物理教学是以实验为基础的，中学物理教材的基础知识，都是以实验为先导，逐步总结出定理、定律等规律性的知识，这是中学物理教学的重要方法，不能忽视。今后中学物理实验教学应包括三方面的内容：一是基本仪器的使用，二是根据实验原理和选用实验器材来进行物理实验，三是正确分析和处理有关的实验数据，从中得出或验证相应的规律。 王泉根：<必须加强物理实验课教学，<山西教育>1 981年第10期。
3．观点摘要
观点摘要是在理解原文的基础上，将原文的主要观点、结论摘要或写出，报刊杂志上的“论点摘编"即属此种。它同样也要写明作者、刊物、出版等情况。例如：数学教学中培养学生解题能力
解题能力包括实际运算能力、空间想象能力、抽象概括能力、逻辑推理能力四个部分。 实际运算能力又可分为两部分：一是对具体数字进行运算的能力；二是对代数式和三角式进行恒等变形的能力。
空间想象能力主要通过几何题目和三角应用题得到锻炼。
抽象概括能力主要包括：1．将实际问题抽象成数学问题的能力；2．从具体的数字运算过渡到抽象的式的运算。逻辑推理能力大致可分为条理性和灵活性两个方面。其中以庆理性为关键，同时也要注意锻炼思维的灵活性。蒋明文：<数学函授研究>1 987年第2期。
