Anxiety refers to an unpleasant feeling, accompanied by a premonition that an unknown event is about to happen, and serious anxiety turns into fear.

According to the survey, at present, a large number of students in China have learning anxiety, which has greatly affected their learning and healthy growth. Students' anxiety about learning also comes from the feeling that the fisherman benefits from an ominous premonition. There are two kinds of learning anxiety.

The first is: anxiety in personality, children are prone to anxiety when they encounter things because of their natural innovation; The second type is: situational temporary anxiety, that is, the anxiety that students feel when something important is about to happen, such as anxiety before school, nervousness before exams and anxiety before homework check, are all manifestations of learning anxiety.

Most middle school students' learning anxiety belongs to the second kind. Students with learning anxiety will have different degrees of anxiety, absent-mindedness, palpitation, dizziness and other symptoms, and even feel headache and palpitation when they see books and enter the classroom. Learning anxiety is caused by learning, but at the same time it opens up students' learning process and academic performance.

Anxious students are afraid and hate learning, and it is easy for them to give up when they encounter difficulties in learning. Therefore, in the process of learning, the mastery of knowledge points will be very unstable, leading to a gradual decline in academic performance.

In this way, anxiety will snowball. For example, some children are extremely nervous before the exam, can't eat well, can't sleep well, and their brains are blank and sweaty during the exam, so they can't write what they can, which leads to a mess in the exam results.

Most students with learning anxiety are middle-level students and top students. For middle school students, on the one hand, they are afraid of being young and looked down upon, but they have a strong desire to learn, on the other hand, they are unable to complete better learning tasks because of anxiety.
