寫筆記的方法

Daniel Lau 發佈於  收錄於 學習

今天看完了一本叫《知道做到：自學的科學》的書，我在書中學到挺多乾貨和受到不少的激勵。我在這書中最大的兩個得着是SQ3R法和康奈尔筆記法。

SQ3R法

  • S： 調查
  • Q： 提問
  • R： 閱讀
  • R：背誦
  • R：復習

康奈尔筆記法

提示栏（Cues） 笔记栏（Notes）
关键词、问题、主题 详细记录、讲解要点、例子等
例如： - 概念1：描述、例子
- 主要关键词1 - 概念2：说明
- 关键问题1 - 图表、数据、说明等

总结栏（Summary）

总结本页内容的核心概念与主要观点，简明扼要地整理重点。
