Primary school is the first step of high school, and is the foundation for students to continue studying at higher levels. Primary school students are all at an innocent age, as innocent and pure as a piece of white paper without a blemish. Teachers, in addition to their teaching duties, also shape students’ personalities every day and every hour. Teachers need to understand the thoughts, aspirations, interests, and talents of each child. Especially in the 4.0 digital age. Children who are given access to technology from a young age by their parents are very smart, active, and confident. Besides, children are also pampered by their parents and family and do not have to do anything, so their life skills are limited.
