A little advice for students - how to build their own knowledge system?

See the students I took , Many people are at a loss about their current state , Want to work hard , I don't know how to do it , Here's how to build your own knowledge system .

1. What is knowledge system ？

A network knowledge structure composed of a large number of knowledge points and their relationships is a knowledge system （ My definition ）
Here are two key points ： Knowledge point （ Fragmented ）、 Relationship

2. Composition of knowledge system ？

2.1 There should be a lot of general knowledge as the foundation

Good general knowledge needs to have the following characteristics ：

1. normal form , This subject studies something ？ How to study ？ At present, there are generally accepted principles ？
2. Extensive , Looking for the latest , The most extensive results , Don't stick to the point of view of a certain school , Don't restrict your vision .
3. objective , Don't have content with positions and tendencies , General knowledge must be objective .

2.2 Know its application scenarios

All the knowledge , Essentially , All exist to achieve a certain purpose . The best way to learn is ： Problem driven ！ There are problems before you explore , So as to enrich and improve their knowledge system , In order to solve the problem . To know its application scenario, we need to understand three problems ：

1. mission , What does this field exist for ？
2. Big problem , What major problems exist in this field to promote the development of the field , How did predecessors think and answer ？
3. A small problem , What I'm interested in , What kind of questions can I ask ？
   Last , Keep abreast of industry information , General knowledge and Application , Together, they constitute the vast majority of the knowledge system , The rest is information , That is, small update packages , Knowledge system is a process of continuous iteration and improvement . Knowledge is not the end , But on the way .

3. How to establish knowledge system ？

3.1 Need a mentor

The role of a mentor is to provide you with an effective learning path . A good learning path must be from easy to difficult , from the shallower to the deeper , Extensive and professional . The best condition is to find the edge of the comfortable area of learning , The next step forward is the growth area , Don't get too far away from the comfort zone at once , Too far to learn .

3.2 Be able to output

Output is the best way to internalize . How to better remember a knowledge point ? That is to say it in your own words , Teach others .

3.3 There should be information channels

Source of fragmentation information , There are mainly the following channels ：

1. Google： No matter what field 、 Any time ,Google It's all the best 、 The most comprehensive source of information
2. The paper ： Domestic use HowNet , For foreign use Google academic +Sci-hub, You can get cutting-edge information in a certain field
3. The media ： Various blog platforms （ Such as CSDN、 You know ） etc. .
4. community ： Wechat groups in various industries 、QQ Group 、 Community, etc .

4 Learning mentality

4.1 contact

Try to find and build , The connection between this new knowledge point and the old knowledge point , It is meaningless to look at a knowledge point in isolation , Can't remember , Nor can it be incorporated into its own knowledge network .

4.2 System

Connection is centered on new knowledge points , Make divergent correlations , And the system is a higher level , Look at the whole network in front of you from a higher dimension .

4.3 to open up

Any field is constantly spiraling , Iterative , Embrace new and different perspectives , Face any field with an open and inclusive attitude , Can't stand on one's own feet .
