The existing problems of college students and the improvement measures are as follows: 1. Classroom scene Students sometimes sleep and play with their mobile phones in class, so they can't concentrate on class effectively and do something unrelated to class. The teacher's hard explanation in each class is actually a kind of labor achievement. A person who doesn't know how to respect the fruits of others' labor, what can he talk about learning? 2, students lack interest in learning, lack of motivation, we must clearly understand that students do not like to study, the most fundamental reason is that before they enter the university, their parents choose their majors according to the current social employment situation or personal views, without fully considering their personal interests and hobbies. This fixed choice or the development space paved by parents makes students mistakenly think that they don't need their own efforts as long as they can get their diplomas smoothly. 3. Students can't arrange and use their study time effectively and reasonably. After three years of hard work in high school, every student is full of yearning for his own university. He has just entered the university campus, and he is curious about everything here, thinking that he should relax and enjoy life when he goes to college. Can not give full play to the initiative and enthusiasm of learning, poor self-care ability, low self-control ability. 4. Without good learning methods, learning efficiency is naturally not high. Universities are places where students learn new knowledge. Teachers should combine their own courses and professional settings, teach scientific learning methods and develop good study habits. Because high school students have developed exam-oriented education for further study. Bad learning methods will only cause great psychological pressure to students, and low learning efficiency will lead to a vicious circle. Encouraging students to participate in various club activities, relax their brains, increase their knowledge, and make their body and mind grow up happily, which is also conducive to improving learning efficiency. What is the root of the problem and how to solve it: (1) Lack of sense of time and competition. After entering the university, they broke away from the "three-point-one-line" lifestyle of middle school. Most students are in a confused period in the first half of the semester, full of curiosity about the new things in the university. Just ask for "Long Live 60 Minutes", don't fail professional courses, and go to elective courses to see your mood. (2) Life pressure is too small to think urgently. As mentioned above, many students have completely abandoned the "five-to-nine" life learning mode in middle schools, thinking that colleges and universities are a platform to publicize their individuality, be completely free and relax themselves, and have no urgent thinking and clear understanding of time, so that they have entered the "time misunderstanding". Based on the above situation, to solve the root cause of the problem from the source, we must trace the source. Only in this way can we better point out the future path for contemporary college students and make them get out of blind spots and misunderstandings as soon as possible. As a teacher, we should deeply analyze the problems, go deep into the students, and understand what the students need and what their interests are.
