two modes of learning, take the pinball game as an example.
metaphor and analogy helps when you trying to learn something new.
Some scientists found that you can only be in one mode at a time. In the focused mode, it helps you get deeper understanding of the subject, but we you trying to think around, there're always lots of bounces there blocking you from getting to another thinking pattern. Then how do you get to know other patterns that you don't even know it exists before? That's how diffuse mode helps.
Question: I still don't understand how to get to know thinking patterns that you don't know(even its' existance) before.
How do you use the two different modes?
In order to learn things more effectively, your brain needs to be able to switch back and forth between the two different modes.
Question 1: Is diffuse mode efficient for more scientific courses?
Question 2: When are you feeling more relaxed/in a diffuse mode?
Question 3: How do you train your brain to switch back and forth between two different modes?
Question 4: 也即是说,只要能让你的大脑在合适的时间使用正确的模式,即能提高效率?那么,如何让大脑进入、转换到想要的模式去呢?如何对此切换进行刻意练习呢?有没有数据统计显示,每个人大脑在各个时间段的默认活跃模式和刻意练习后的活跃模式呢?难道,记录时间是提供此一数据的最有效途径?
One interesting thing is that on those things that we practiced so much to master computers are way faster and better than us, but on those things that we are mastering naturally since we're born, like walking, seeing, hearing, feeling, are way complex for computers. We don't know how we walk/see/hear but we just good at it. There're millions of neurons underlying working together as patterns to help us finish these tasks .
为何会产生?遇见不愉快的事情 cue -> 大脑(下意识地)转向更愉快的事情(比如刷网站等)reaction -> 获得愉快感 reward 。它有好有坏,也有中性,但有些拖延确实影响了你做更重要的事情。
如何克制:番茄工作法。但我突然顿悟:番茄工作法和 TDD 一样,都是理念看起来简单,实践看起来简单,但是实践好不简单。我实践番茄的时候还是原来怎么做就怎么做,除了物理上开启一个番茄钟,但是被打断了或者主动打断我都无所谓,按照原来的节奏做。做到25分钟也不停下,有时还要赖上一段。停下了也没好好休息,或者一休息就半个小时,又开始拖延起来。直到一切停止后,才发现原来番茄还没停下,然后才伸手把番茄钟关掉。
说没做番茄吧,我形式上也是做了。但其中的关节:专注、中断、休息,我是一个都没按照方式训练修行,还是依照原样。没意识、不愿意花时间学习、反省关键实践,还是依照大脑舒服的路径走,还自以为已经获得了精髓,不就是帮你专注嘛。然后就又得出结论:这东西你掌握思想就好了,实践照不照做一样的,感觉这技术也不过如此,没什么卵用,比我自然学习的时候还更不自在呢。
TDD 的关节技术:任务分解、设计、测试、最简实现、重构;核心思想:快速反馈、刚好合适完成。需要对照,理解,实践。有人说,我感觉还是得看人,看情况,看项目,看团队。掌握了核心思想就可以了,实践还是因人而异。啥事都因人而异,都具体情况具体分析。
只介绍两种类型的记忆:长时记忆 long term memory 和 工作记忆 working memory。
Spaced repetition 方法可以帮助你将工作记忆存储到长时记忆中
人清醒/活动时,会产生对大脑有害的物质 toxic, 而睡眠可以帮助你洗去这些毒素。除此以外,睡眠对于本课程中提到的很多过程也是有益的,比如:
当然,过多或过少的睡眠都是不好的,可能会有焦虑,精神不振等副作用。那么如何判断睡眠够了没有?有没有普通标准?睡眠过多过少会有什么副作用?
采访课程的另一位老师:你是如何高效学习的呢?你研究的结论是如何应用到自己学习中去的呢?
A chunk means a network of neurous that are used to firing together. Chunking is the mental leap that helps you unite bits of information together through meaning.
My understanding: chunks are groups of information that you access and use. The idea is about:
Forming a mental or physical chunk could be different in details but there're basic ideas:
context[step 4] is where bottom up and top down meets - what does that mean?
Having a book/google presenting in front of you doesn't mean that you HAVE those information/knowledge in you mind. You have to wire the information and even knowledge into your brain's circuity by recalling,
neuromodulators also impacts your unconscious mind:
introduction: this week we'll talk about two seemingly different topics: procrastination and memory, but are actually intimately related. why? because building good chunks that are easily accessed by your short term memory takes time. and we'll talk about how procrastination happens and simple ways that don't require much will power to tackle it.
procrastination shares the similar feature with addition:
Habits are developed to save energy. Habits can be good, harmless, or harmful. How habit works is in four key parts:
By focusing on product, your goal was the output and you could get nervous/anxiety about how far/close you are to the result. This makes your brain more likely to procrastinate.
By focusing on process rather than product, you allow yourself to back away from judging yourself, am I getting closer to finishing? And instead you allow yourself to relax into the flow of the work. The key is when a distraction arises, which it inevitably will, you want to train yourself to just let it flow by, and your brain would less likely to procrastinate, and thus productivity and positive moods coming.
Processes relate to simple habits, habits that coincidentally allow you to do the unpleasant tasks that need to be done.
Visualise system helps you memorise things, like where it's located, how does it looks like, etc. Images can pack lots of information to help you remember and retrieve the image and information compacted. There're some steps/guidelines to build and strengthen your memory from short-term memory to long-term memory:
There're two essential parts of your memories system:
这周课程是为了让你获得以下能力。不过开播前要知道一个前置理念:即学习不是知识线性增长的过程。有时你会遇到瓶颈,有时会觉得以前会的好像现在都不会了,觉得一片浆糊、知识体系崩塌,不知所以。这是因为你的大脑在努力消化知识,跨过了一般就有逆天提升:更坚固的基础,更完备的体系。所以遇到瓶颈了别虚。
建议:
一小时测试能学到的东西可能比一小时学习来得多,要享受测试这种方式。如何保证测试取得好的结果呢?有人做了一个清单,只要你做到了上面提到的所有条目,那就可以认为测试一定会成功:
厉害了。比如一个测试,或者拿到一份前端技术路线图,你会先挑容易的学,还是困难的学?理由?
此法关键在于,具备一遇到障碍马上抽离的意识和自制力。没有的话就要培养。
首先是给考试焦虑的同学的一些小建议。说这个焦虑的时候,身体会产生一些化学物质,这个不重要,重要的是你怎么解释这种现象。只要正能量,就可以改变身体的感知方式。
然后是一些来自其他领域有名学习人士的建议:
@JimmyLv 插楼删~
可喜可贺。
恭喜恭喜!
