Why am I always absent-minded or in a daze in class?

There are many factors that affect attention. First of all, physiological reasons are very common, such as physical discomfort, headache, stomachache, fatigue, the smell of the same table, the stimulation of light and so on. These are high risk factors for distraction. In addition, students dislike teachers, quarrel with classmates after class, etc. It's all the reasons why students can't get into the classroom quickly. And everyone's attention has a certain time limit. The younger you are, the shorter your attention span will be. According to my statistics, for primary school students, the time to keep their attention is often less than 5 minutes. Even for middle school students, the number of absences within 10 minute will be as high as 3-6 times, or even more. Even if adults attend classes, there is no guarantee that they will not be distracted from beginning to end! So in class, it is impossible to keep 100% concentration from beginning to end! Not to mention children. Therefore, the requirement for children's concentration in this respect is to hit their own mouths! To this end, parents should be concerned about whether their children can create the greatest learning results in a limited time.
