The secondary school stage is the transitional stage of a person’s maturity. A person’s character is basically formed at this stage, and various problems arise as they face too many changes. Physiological development The maturation of body organs, especially the rapid development of sexual physiology, causes them to develop a budding sexual consciousness. They start to pay attention to the opposite sex and have the desire for sex. Inevitably, they will encounter unanswered questions, and because they are too shy to talk about it, it is easy to have deviations in their sexual understanding or generate wrong concepts and behaviors. Common problems include excessive tension in heterosexual interactions, sexual anxiety, poor sexual identity, negative true guilt after masturbation, early love, etc. In terms of self-awareness development, middle school students gradually have a sense of “adulthood”. Due to the poor grasp of themselves, the development of self-awareness may lead to over-evaluation of themselves, self-centeredness, lack of opinion and independence due to excessive herd mentality, excessive self-rejection, excessive self-esteem, inferiority complex and vanity, and contradictions caused by the conflict between the ideal self and the real self. Psychology. Secondary school students gradually transition from dependence on their parents to independence and prefer to make decisions based on their own judgment. At this stage, parents and children are most likely to have conflicts and unhappiness. Learning aspect Every student wants to do well in their studies, but some have improper learning methods, no interest in learning, school phobia, depression or anorexia, jealousy, low self-esteem, declining self-confidence, etc.
