The people's daily and the Chinese English wechat of the Communist Youth League once published an article entitled "sleeping college students: you are not unemployed, it's natural that you are embarrassed". At the same time, with the picture, you fall asleep in the university classroom, which makes you feel very sad. So it's easy to criticize universities and college students' indulgence on the Internet, but it's the most difficult to change and do it. Otherwise, you will talk on paper and talk freely, It doesn't help.

Recently, the experimental course "preparation of special ceramics by high temperature synthesis" has a total of two class hours, one class hour lecture + one class hour experiment mode. The content of the lecture includes the history, development, theory and application of combustion synthesis. The experiment includes a demonstration experiment and an experiment operated by a student himself. Although only two class hours, the theory and application coexist, and the phenomenon and principle coexist, And it is closely connected with the professional knowledge of materials science and engineering that we have learned and are learning. The students observed the experimental phenomenon similar to rocket propellant combustion, showing excited and surprised eyes. But what about the experimental report?

More than 60 copies of the experimental reports were handed in and doubled, which reminds me not only of the experimental reports of previous years, but also of no progress. Most of the students copied the experimental instructions once, referring to the experimental objectives, principles, instruments and drugs, and steps in the experimental instructions, which has been copied to two pages, The better students describe the observed experimental phenomena, or think a little expansively from the perspective of society and environment, while the teacher needs and expects the most about the natural science principles of experiment, especially the analysis of specific experimental materials and technology. What does it mean? Students did not look up the data, on the phenomenon of phenomenology, on the phenomenon of writing phenomenon, through the language of a natural phenomenon of laboratory design were described, "I wave a sleeve, do not take away a little science." Therefore, this kind of experimental report writing method may not need college students, a high school student has the ability to complete, or even better.

What is the reason for this phenomenon? Unwilling to learn? Not interested in learning? No time to learn? In short, there is no extensive learning, no research learning, no thinking learning.

However, the University Libraries in our country are excellent, spacious and bright, and have a large collection of books. But how many students study in the library? How many students go to the library to look up materials and carry out research study? It is worthy of investigation and analysis.

Further thinking, what are the reasons for students' lack of expansibility and research-based learning? Based on my own thoughts and current situation when I went to university more than 20 years ago, I summarized the following aspects:

1. The confusion of University. The stage before high school is the only goal oriented learning. The baton of the college entrance examination is high, the learning goal is clear, the tutoring class is day reading, the topic is brushed, the junior high school, the senior high school, the university course is studied in advance, all kinds of chicks can't lose in the starting line, and so on. Its goal is "good" University, and it has become the public knowledge of the whole society, known to all ages, with the same idea. However, the ultimate goal of the university is to work. Where is the work? Where do you work? How much is the income? It looks like a bright future, but in fact, it's a misty landscape. So there is a sense of learning confusion, this phenomenon also appeared in my junior year, freshmen and sophomores with high school aftereffects and ways, junior suddenly confused, do not know why to learn?

2. The transformation of the way from the brush topic learning to the thinking learning. After all, the content of high school is limited, and most of the knowledge of freshmen and sophomores is established knowledge. For example, advanced mathematics, college physics and so on are the learning of classical knowledge. Although there are many contents and fast learning, there is almost no room for research-based learning to develop from brush topic learning to flexible application learning. However, the study of professional courses is different. Many of them are closely related to the scene, technology, etc., and there are many small uncertainties in the case of big certainty. Moreover, technology and methods are constantly developing and updating at any time. They need to be transformed into thinking learning, at least the developmental learning of consulting materials and literature argumentation. However, most students have not experienced such training, There is no one to teach the actual learning method, so we can only explore the detour by ourselves, so we don't know how to consult the literature, summarize the literature, and demonstrate the phenomenon. Although I had studied literature retrieval courses in my freshman year, I didn't feel that it was applied specifically. Later, I learned to search materials and research topics at the graduate stage; In addition, in the past, there was no library in primary school, junior high school and senior high school.

3. No time to learn. Some undergraduate professional training programs often take 190 or even 200 credits, and students are tired of learning all day long. After this class, they rush to that class, one after another, and a pile of homework after another. In addition to dealing with ordinary homework, they really can't afford time for thinking and expanding learning. In addition, extended learning does take time to consult, filter, summarize, summarize literature, and demonstrate phenomena. It's a brain burning activity. Maybe we once carried out extended learning with full enthusiasm. After practice, we found that the effect is not good, or it's better not to expand. Time is the best "medicine" to discuss the phenomenon on the basis of the matter. In addition, bad money may drive out good money, Simply do not carry out extended learning.

4. I'm not interested in learning. I'm not interested in a certain course, or assume that the interest in games takes up too much time. Although I know how to learn, I'm not interested in it. I'm not willing to carry out extensive learning. I can cope with it.

What should we do to solve these problems?

1. Strengthen the research and teaching of learning methodology. It seems that there is no special similar course in the University. Although there may be a course of philosophy of science, there is not much about integrating theory with practice. Therefore, the learning method mainly depends on the students' own exploration, imitation, influence, and the teacher's dribs and drabs. However, it is not systematic enough. I feel that learning is very easy. Who can't learn and who doesn't know how to learn? In fact, learning also has skills It is necessary to strengthen the research and teaching of learning methodology for students to improve their learning ability and efficiency.

2. Everyone's path is his own choice. Although the vast majority of students' experimental reports are copied from the experimental instructions, and they are porters, without much thinking and expansion, there are always a few students who have spared no effort to write more reading and thought-provoking reports, so they will get higher scores. Because of thinking and investment, I believe they will be better on the road of life.

3. Universities should be lenient in and strict out. In 2020, the gross enrollment rate of college entrance examination (including junior college) in China has reached 54%, and higher education has entered the stage of popularization. Looking at the history of our university, the examination of universities in the 1930s was very strict. Although many people became famous later, there are many failures in the university stage, so strict requirements are conducive to the cultivation of talents.

How to write the experiment report? Based on the literature review, the experimental principle is analyzed, the thermodynamic data is searched, the adiabatic temperature is calculated, and the microstructure, structure, performance and application of materials are predicted. Combined with the microscopic analysis method of materials being studied, the hypothetical identification of materials is carried out, and the results are predicted, and the possible problems and improvement and modification schemes are put forward.

Moving learning can not cultivate innovative talents, only constantly thinking, the brain will be better and better.

Think more and find out the scientific truth behind things. I believe that those who are good at thinking will always be favored by opportunities. Expanding from phenomenological phenomena to finding the essence of phenomena and principles of phenomena will certainly contribute to original innovation and contribute more to the development of individuals, families and society.
