From problem-solving to problem-solving to research and innovation

Inscription: No amount of dead knowledge is of much use.

Obviously, I have learned a lot of knowledge consciously, but when I actually started to do the questions, there was still the dilemma of "one pen, one hand, one Leetcode for one night"? Have you ever had such an experience, the question type is not too difficult, and you can figure it out by reading the solution, but when you do it yourself, you look at the question face to face and have no way to start. Is this dilemma bothering you now or has it been overcome by you? Come share your troubles and suggestions!

AI nonsense:

I understand the dilemma you're describing, it's really common when learning and problem solving. Here are some of my suggestions to help you overcome this dilemma:

1. Practice is the only criterion for testing truth: Although you have learned a lot of knowledge, practice is the way to better understand and master knowledge. Through continuous practice, you can develop a deeper understanding of knowledge and develop problem-solving skills.
2. Deliberate Practice: Improve your problem-solving and thinking skills through deliberate practice. You can choose targeted practice questions and practice repeatedly until you can solve similar problems proficiently.
3. Break down the problem: Faced with a complex problem, you can try to break it down into smaller parts. This can make the problem easier to solve, and it can also help you better understand the overall structure of the problem.
4. Seek Feedback: Seeking feedback from others is very important in the learning process. You can ask your teacher or classmates for advice and listen to their suggestions and opinions on your understanding and problem-solving methods, so as to better understand your own strengths and weaknesses.
5. Persistence: Learning is a long-term process that requires persistent efforts. When encountering difficulties, don't give up easily, but persist in learning and practicing, constantly overcome difficulties and accumulate experience.

In general, to overcome this dilemma requires continuous learning and practice, while maintaining a positive attitude and persistent efforts. I hope these suggestions can help you, and I wish you better results in the process of learning and solving problems!

personal opinion:

Due to time constraints, let me just briefly talk about it from the perspective of the mental model:

111 The thinking model of mechanical memory , as the saying goes, is rote memorization, which not only reduces the learning effect, but also makes people's thinking rigid and restricts their intellectual activities. For the text class, recite the content, and for the program class, forcefully memorize the thoughts of others instead of training your own thoughts. This is the aforementioned " one pen, one pair of hands, one Leetcode for one night ".

Solution: After completion, you must use your own way of thinking to change the solution to reproduce each question.

222 Understand the design thinking model , design includes logic, etc., with the help of active thinking activities, by understanding the meaning of things,..., through the nature of things and their internal connections, grasp the structure, level and thinking of things or programs, and design way of thinking. (Given a data, the proportion of people who master this kind of thinking is very low.)

If it is a 111 type of thinking, no matter how many questions you write, it is of little use. Unless you take the original question, it is of little use.

The title of this article is "From problem solving to problem solving to research innovation"

The ratio of solving problems to solving problems is 1:99;

Problem Solving to Research Innovation 1:99.

In practice, we use a ratio of about 1:9, and there are also 28 laws and so on.

This leads to a situation where the winner takes all and most people run with them.

1. Share your own experience

Tip: Summarize the reasons why it is difficult to brush simple questions, and elicit the importance and purpose of solving this problem

AI makes up stories:

I have also encountered similar problems. Although I have learned a lot of knowledge in the process of solving problems, I found that my ability is not enough to solve some seemingly simple problems in actual operation.

The main reason for this dilemma may be that our knowledge is not solid, or we lack a deep understanding of the topic. This may be because we do not fully understand the concept during the learning process, or lack of exploration of the rationale behind the problem. So even though we seem to have acquired knowledge, we have difficulties in practice.

Faced with this situation, we need to adopt some strategies to overcome it. First, we need to revisit our fundamentals to ensure we have a solid understanding of concepts and principles. This may require us to re-read the textbook, or attend additional tutorial sessions. Second, we need to develop problem-solving skills, which can be tackled through deliberate practice and thought. We can choose some practice questions, especially those that can exercise our thinking, and practice repeatedly until we can solve such problems proficiently.

Also, seeking feedback is very important. We can ask teachers or classmates for advice and listen to their suggestions and opinions on our understanding and problem-solving methods. This feedback can help us better understand our strengths and weaknesses, which can guide us to improve our problem-solving methods.

Finally, the spirit of perseverance is also essential. Learning is a long-term process, we need to maintain continuous efforts, continuous learning and practice. When we encounter difficulties, we should not give up easily, but should persist in learning and practicing, constantly overcome difficulties and accumulate experience.

Generally speaking, overcoming this predicament requires our efforts and persistence. By revisiting the basics, developing problem-solving skills, seeking feedback, and persevering, we can gradually improve our problem-solving abilities and better apply what we learn in practice.

2. Analyze possible problems

Tip: Check your own learning status and subject mastery, explore possible learning obstacles and confusion, and determine the root cause of the problem, such as learning methods, attitudes, knowledge reserves, etc.

AI：

When analyzing your own learning status and subject mastery, there may be the following problems:

1. Learning methods: Learning methods can affect how well we learn. If our learning method is not suitable, it may make it difficult for us to understand or master knowledge points in the learning process. For example, if we do not have a mindset or approach to learning that is appropriate to the subject, we may have difficulty learning.
2. Attitude and motivation: Attitude and motivation to learn may also affect how well we learn. If we lack motivation and enthusiasm, it may cause us to have difficulties in our studies. We may lack attention and attention to our own learning and lack of continuous learning motivation, which makes us unable to persist in learning or feel powerless when solving problems.
3. Knowledge reserve: Knowledge reserve is also an important factor affecting our ability to solve problems. If our knowledge reserves are insufficient, we may not be able to understand the background and requirements of the topic, making it difficult to solve the topic. For example, if we do not have the relevant basic knowledge or do not have a deep understanding of the concepts and principles of the subject, we may find it difficult to solve problems.

In order to solve these problems, we can take the following measures:

1. Adjust learning methods: We can try to find a learning method that suits us, such as reading, listening to lectures, practicing, etc. to improve our learning effect. We can also try to use some learning tools, such as notes, mind maps, etc., to help us better understand and remember knowledge points.
2. Stimulate learning motivation: We can try to find ways to motivate ourselves to learn, such as making study plans, setting goals, or rewarding ourselves. We can try to find the joy and motivation of learning, so that we can devote ourselves to learning more actively.
3. Consolidation of knowledge base: We can review our basic knowledge to ensure that we have a solid understanding of the basic concepts and principles of the subject. We can also expand our knowledge by reading related books, taking courses or communicating with others.

By identifying and addressing these problems, we can improve our own learning and thus better deal with the challenges of problem solving.
