It is a common phenomenon for middle school students to study partial subjects. There are mainly these situations: there are deviations in liberal arts or science; There are separate courses, and other courses are common; All other subjects are good, except one, such as foreign languages. This situation is becoming more and more common in high schools. As parents, we should carefully analyze the causes of children's partiality and find out the solutions. There are two reasons why science or liberal arts are biased; The first is to understand the problem. Some students are influenced by the concept that "if you learn math and physics well, you can find a job". They attach importance to science and are afraid of reciting liberal arts, so they can't master the methods well. Some students simply lost their liberal arts. Second, the teaching of arts and sciences in senior high schools has prompted some students to give up arts (science). In fact, the above and science complement each other. The main reason for autonomous learning is that some children are particularly interested in a certain subject. Interest is people's special cognitive tendency towards things. This is because, in addition to the persistence and stability of this cognitive tendency, this cognitive tendency is always accompanied by positive emotions such as joy, joy and satisfaction. So they are particularly interested in this subject. Doing homework is full of enthusiasm, and the main energy is spent here, which affects its subject. There are only one or two differences for three reasons: first, children may not be interested in this course. Second, the primary school foundation is poor. Third, if the students in a certain course are all poor, it may be the way for teachers to educate them. If it is a teacher's problem, parents should report it to the school. What should children do when they study partial subjects? First of all, we should find out the situation, analyze it carefully, find out the reasons and be aware of it. Then focus on education to make children realize the importance of comprehensive knowledge. Children have a poor foundation, so parents should help them make up lessons. If they don't have this knowledge, they can go to school to ask teachers for help, or ask tutors to make up lessons. Interest should be cultivated according to children's different learning interests. Those with poor interests should be taught, such as those with poor mathematics. Make it clear that mathematics is the foundation of all natural sciences and learn physical chemistry well. Raising awareness through education can not only cultivate children's positive interest and overcome negative interest, but also adjust the relationship between various interests, making it a favorable factor for children's learning activities. If the interest in a subject is too strong to control, it is necessary to guide children to develop in the direction of interest in other courses, so as to achieve a comprehensive balance and mutual promotion.
