The middle school stage is a period in which teenagers grow physically, intellectually and intellectually, and their moral quality and world outlook are gradually formed. During this period, teenagers are faced with sharp changes in physiology and psychology, and with intense study, they are prone to psychological maladjustment and psychological contradictions. To sum up, there are probably the following aspects: 1. The contradiction between good wishes and psychological preparation. Almost every student has good wishes and is full of longing for the future. Many students fantasize about being a learned and respected person. In fact, many students don't study hard, and every day counts. Although the wish is beautiful, all they pursue is all kinds of honors and enjoyment after realizing the ideal. However, to realize the ideal, we need to start from now and pay hard work, but we don't think much and do enough, which forms the contradiction that the good wish is out of touch with psychological preparation. 2. The contradiction between a strong sense of enjoyment and a weak concept of labor. With the improvement of living standards, some students' consumption desire is increasing day by day. Many students buy snacks every day, and it is very serious to reciprocate and compare with each other. However, quite a few of these students have a weak concept of labor, despise labor, and hate the usual work of students on duty. It can be said that the idea of taking a negative attitude towards labor and hating labor is quite common. 3. The contradiction between psychological atresia and desire for understanding. Due to the development of self-awareness, students began to focus on their inner teachers and sisters, and at the same time, due to the gradual enrichment of social life experience, they realized that there are characteristics of mutual affinity and psychological incompatibility between people. Willing to talk with intimate friends, unwilling to reveal their hearts with their elders, and practicing self-isolation. These students hide their inner feelings, which often leads to loneliness. In fact, these students and others need to understand, but they only complain that their parents and teachers don't understand themselves. 4. The contradiction between independent consciousness and dependence psychology. With the increase of age and the emergence of adult consciousness, students' psychology is becoming more and more mature, and they are required to be liberated from the constraints of adults. Some students will also contradict their teachers and even have resistance to the school and society. It can be said that their sense of independence is very strong, but at the same time they lack the necessary knowledge and ability, and they are dependent on their economic life. Some students really live with their mouths open and their clothes stretched out, just studying regardless of other abnormal phenomena. 5. The contradiction between emotion and reason. Middle school students are full of enthusiasm and passion, but their emotions are easily influenced by the outside world. Emotion and emotion are always swinging at the poles, so it is difficult to control their emotions calmly and rationally in time. 6. The contradiction between strong enterprise and weak self-control. Most students are positive and enterprising, but because they don't think carefully, they often look at people and things around them with strong emotional color, so sometimes they stick to their own opinions unilaterally, can't control themselves, act on impulse, and regret it very much after the incident. The development of the quality of speaking will is still immature, and self-control and control are not strong. 7. The contradiction between the expansion of information vision and the lack of identification ability. Students are in an information-based society, and they are very enthusiastic and curious about all kinds of information and actively explore it. However, because the world outlook and outlook on life have not yet been fully formed, the discrimination between truth, goodness and beauty, falsehood, ugliness and ugliness is not strong, and their understanding of things is often narrow, and they are easily confused by superficial phenomena, resulting in cognitive errors. In this case, some unhealthy ideology will easily enter the hearts of classmates and affect the healthy growth of teenagers. 8. The contradiction between desire for success and weariness of learning. Most students hope to get excellent academic performance, but in the process of learning, they feel that the burden of learning is too heavy, learning is too hard and too tired to persevere, and their weariness of learning has increased sharply, forming a psychological contradiction between wanting to learn and being tired of learning. In a word, the psychological contradiction of middle school students is complicated, and its causes are physiological and psychological, social, family, self, and negligence in education. A correct understanding of these contradictions is not only conducive to our classmates' self-awareness and improvement, but also conducive to teachers' mental health education and the healthy growth of young students' body and mind.
